Six electrical outlets are disposed within the side panels of the clock casing, electrical power to each of the outlets being controlled either by the main face clock or one of the three associative clocks, singly or in combination and in a simultaneous or alternative fashion. The clock movements include appropriate gearing for indicating the time appearing upon the respective clock faces as well as means for actuating electrical switches associated with the electrical outlets whereby electrical power to the outlets may be automatically supplied or terminated. In addition, additional electronic circuitry and switching means are provided whereby electrical power to all the electrical outlets may be manually supplied or terminated, as well as for facilitating the automatic control of electricalpower to particular outlets by several of the clocks.

20 Claims, 8 Drawing Figures PATENTEB FEB! 8 I975 SHEET 2 BF 3 will I a m V W U 8 w 0% l M l l l El W flmmm/im 5 FIGB MULTIPLE-SWITCH CLOCK BACKGROUND OF THE INVENTION The present invention relates generally to clocks and more particularly to an improved multiple-switch clock for controlling the supply or termination of electrical power to a plurality of electrical outlets housed within the clock casing.

Clocks and timing devices are of course well known, the entire gamut extending from a clock having a simple movement which merely facilitates the indication of the particular hour of the day to those clocks having complex movements which include various mechanisms for controlling the actuation or cessation of other devices or systems.

For example, kitchen appliances, particularly ovens, often have timer mechanisms associated therewith whereby the oven may be automatically activated at a particular time, or having already been manually placed in operation may be automatically de-activated. In addition, such conventional ovens may also have electrical outlets associated therewith such that other kitchen appliances may be plugged into the outlet receptacles whereupon the appropriate setting of the timer mechanisms, actuation of electrical switches associated with the electrical outlets will occur at the particular times set, the appliances thereby being activated or de-activated.

Similarly, other conventional timer mechanisms have been utilized to automatically activate or de-activate residential lighting systems, lawn water-sprinkling systems, or the like. In this manner for example, the lighting system may be automatically actuated at dusk or de-activated at dawn, or in connection with the lawn sprinkling system, such may be automatically actuated while the owner will be away from the home so that the lawn may nevertheless be watered at a particular time of the day, or having been manually actuated by the owner, the sprinkling system may be automatically deactivated at a particular time of the day when the home-owner is not at home.

These conventional timing devices however, are solely unidirectional, that is, they are only capable of being automatically actuated, necessitating manual deactivation, or having been manually actuated, may be automatically de-activated. It is often desired however that particular individual timing devices be capable of automatic actuation and de-activation in order to be able to perform a plurality of interrelated operations simultaneously, sequentially, or cyclically.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an improved multiple-switch clock which can be adapted to a conventional alarm clock.

Another object of the present invention is to provide an improved multiple-switch clock which has associated therewith a plurality of electrical outlets with which a plurality of electrical devices may be electrically connected so as to be time-controlled.

Still another object of the present invention is to provide an improved multiple-switch clock which has associated therewith a plurality of electrical outlets and which is capable of automatically supplying and/or terminating electrical power to the outlets whereby a multitude of electrical devices connected with the electrical outlets may be automatically activated and/or deactivated.

Yet another object of the present invention is to provide an improved multiple-switch clock which has associated therewith a plurality of electrical outlets and which is capable of automatically supplying and/or terminating electrical power to some of the outlets simul taneously while automatically supplying and/or terminating electrical power to the remainder of the outlets in an alternative fashion.

It is a further object of the present invention to provide an improved multiple-switch clock which has associated therewith a plurality of electrical outlets and which is capable of automatically supplying electrical power to the electrical outlets for periods of time of different duration.

A yet further object of the present invention is to provide an improved multiple-switch clock which has associated therewith a plurality of electrical outlets and which is capable of automatically supplying electrical power to a particular outlet only when electrical power to other particular outlets has been terminated.

A still further object of the present invention is to provide an improved multiple-switch clock which has associated therewith a plurality of electrical outlets and which also includes control mechanisms which are capable of controlling the supply of electrical power to the outlets either singly or collectively.

Yet another object of the present invention is to provide an improved multiple-switch clock which has associated therewith a plurality of electrical outlets and a multitude of corresponding indicator lamps which provide a visual indication of those outlets receiving electrical power which is being utilized to operate electrical devices connected to the particular outlets.

The foregoing objectives are achieved according to this invention through the provision of a multipleswitch clock having a conventional main face clock and three other clocks the faces for which are disposed upon the main clock face at locations corresponding to the 10 oclock, 2 oclock, and 4 oclock positions of the main face. The clock of the present invention also includes six electrical outlets disposed within the side panels of the clock casing, electrical power to each of the outlets being controlled either by the main face clock or one of the three associative clocks, singly or in combination and in a simultaneous or alternative fashion. The clock movements include appropriate gearing for indicating the time appearing upon the respective clock faces as well as means for actuating electrical switches associated with the electrical outlets whereby electrical power to the outlets may be automatically supplied or terminated. In addition, appropriate electronic circuitry and switching means are provided whereby electrical power to all the electrical outlets may be manually supplied or terminated, as well as for facilitating the automatic control of electrical power to particular outlets by several of the clocks.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to the drawings, and more particularly to FIGS. 1, 2 and 4 thereof, a front plate 10 serves as an anchoring base for the clock movement, three switch gears 12, 14, and 16 being mounted therein by means of forwardly projecting, axially extending, tubular sleeve members 18, 20 and 22, respectively. The gears 12, 14 and 16 are disposed rearwardly of front plate 10 while the respective sleeve members project forwardly of plate 10 through respective apertures 24, 26, and 28 provided therein, U-shaped lock washers surroundingly engaging the projecting sleeve members so as to secure the gears relative to plate 10.

The gears 12, 14 and 16 are utilized for manually setting the time at which appropriate electrical switches associated with respective electrical outlets 4, 5, and 3 of the clock, as shown in FIG. 5, will be actuated to their open positions whereby electrical power being supplied to such outlets will be terminated. The electrical outlets are located upon the side panels 21 and 23 of the clock casing 25 which encloses the plate 10 and the associative clock movement, and the respective time periods for actuation of the switches are indicated by respective hands 27, 29 and 31 which being similar to conventional alarm-setting hands provided upon conventional alarm clocks, are respectively secured to the forward portions of sleeve members 18, 20 and 22, and are located upon a clock 33 which is disposed within, and located at the two oclock position of the main face clock of the present invention, a clock which is disposed within and located at the four oclock position of the main face clock, and the main face clock 37 respectively. It will be noted that the clock 33 is a 24-hour clock whose face is divided into two sections of 12 hours each which of course correspond to the A.M. and RM. portions of the day, while the clock 35 is a 24-hour clock having a 24-hour face. The main clock 37 is a conventional l2-hour clock having a 12- hour face, and is disposed within the forward portion of casing 25.

A transmission gear 32, mounted within front plate 10 by means of an axial staff 34, is disposed rearwardly of plate 10 while staff 34 projects forwardly thereof through a hole, not numbered, provided therein. C0- axial with gear 32, there is mounted upon the forwardly projecting portion of staff 34 another transmission gear 36 which intermeshes with still another transmission gear 38 which may be secured forwardly of but within front plate 10 by means of a dowel and washer, both of which are not shown. Transmission gear 38 in turn intermeshes with still another transmission gear 411 which is also disposed forwardly of and mounted within plate 10 by means ofa staff 42, that portion of staff 42 which projects rearwardly of plate 10 serving to co-axially mount a pair of transmission gears 44 and 46. All of the transmission gears 36, 40, 44 and 46 are identical to one another in size, while transmission gear 32 is twice as large as such gears.

Transmission gear 44 is interposed between and interengages with a pair of trip switch gears 48 and 50 which are respectively disposed rearwardly of and coaxially mounted with switch gears 12 and 14 by means of forwardly projecting, axial, tubular sleeve members 52 and 54 which are of such diameter as to facilitate their insertion within the respective sleeve members 18 and 20 of gears 12 and 14. Similarly, transmission gear 46 is interposed between and intermeshes with another pair of trip switch gears 56 and 58 which are respectively disposed forwardly of and co-axially mounted with a pair of switch gears 60 and 62 by means of rearwardly projecting, axially extending tubular sleeve members 64 and 66 which are adapted to be slidably positioned over the respective, forwardly projecting axial staff members 68 and 70 of gears 60 and 62. Switch gears 60 and 62 are similar to switch gears 12 and 14 and are utilized for manually setting the time at which the appropriate electrical switches associated with respective electrical outlets 4 and 5 will be actuated to their closed positions whereby electrical power may be supplied to such outlets, the respective time periods being indicated by respective conventional alarmtype setting hands 61 and 63 which are secured to the front portions of staffs 68 and 70 and are located upon the clocks 33 and 35 respectively. In order to differentiate between setting-hands 27, 29 and 31, and settinghands 61 and 63, the former set of hands may be colored green while the latter set of hands may be colored red.

In a similar manner, trip switch gears 48 and 50 are provided so as to enable the automatic actuation of the appropriate electrical switches associated with respective electrical outlets 4 and 5 whereby in accordance with the time set by the switch gears 12 and 14, and indicated by hands 27 and 29, respectively, electrical power to the respective outlets will in fact be terminated at the time indicated by hands 47 and 49 which are set with the time indicated upon the main clock 37. Likewise, trip switch gears 56 and 58 provide for the automatic actuation of the appropriate switches associated with the respective outlets 4 and 5 whereby in accordance with the time set by the switch gears 60 and 62 and indicated by the hands 61 and 63, respectively, electrical power to the respective outlets will in fact be supplied at the time indicated by hands 47 and 49. To accomplish these switching operations, each of the switch gears 12, 14, 60 and 62 includes a pair of rigid, arcuate-shaped, leaf-type cam surfaces 72, 74, 76 and 78, respectively, mounted in diametrically opposed fashion upon those surfaces of gears 12, 14, 6th and 62 which respectively face trip switch gears 48, 5t), 56 and 58, so that the cam surfaces may mate with arcuateshaped slots 80, 82, 84 and 86 which are provided within the trip switch gears.

disposed about staff 68. In a similar manner, a second L-shaped switch finger holder 96 for mounting another pair of elongate finger switches 98 and 100 is also secured to front plate 10 such that the switches 98 and 100 may be interposed between trip switch gears 50 and 58, the switches being provided with switch actuating portions 99 and 101. Staff 70 of switch gear 62 is inserted through apertures respectively provided within switches 98 and 100, and a coil spring 102 is interposed between, and concentrically disposed about, switches 98 and 100, and staff 70, respectively.

In this manner, coil springs 94 and 102 respectively bias the finger switches 90, 92,98 and 100 into abutting relationship with the trip switch gears 48, 50, 56 and 58, which are in turn respectively biased into abutting relationship with switch gears 12, 14, 60, and 62, contact between the gears being made through means of the cams 72, 74, 76, and 78. Consequently, in operation, when trip switch gears 48, 50, 56 and 58 are rotated in accordance with the clocks movement, the respective slots 80, 82, 84 and 86 provided therein will be aligned with the respective cam surfaces 72, 74, 76, and 78 at those time periods respectively set by switch gears 12, 14, 60, and 62, whereupon the trip switch gears will, under the influence of springs 94 and 102, be moved axially relative to the respective switch gears, such movement in turn permitting the axial movement of finger switches 90, 92, 98 and 100, whereby actuation of the appropriate electrical switches will occur which will terminate or supply electrical power to the outlets 4 and 5, respectively.

Still referring to FIGS. 1, 2 and 4, the switch gears 60 and 62 are respectively provided with rearwardly projecting, axially extending stud portions 104 and 106 which may be inserted through respective apertures 108 and 110 provided within a rear clock movement housing plate 112 for securingly mounting the respective gear assemblies within plate 112, rear plate 112 in turn being secured relative to front plate 10 by means ofa plurality of studs 107 and nuts 109 which also have associated therewith a plurality of Z-arms 111 which serve to secure the entire clock movement within the clock casing 25. Furthermore, in order to facilitate the manual setting of hands 27 and 61, a set stem 114 is inserted through an appropriate aperture provided within rear plate 112 and a set wheel 116, slidably positioned upon the shaft 118 of stem 114, is rotatably. secured to the front surface of rear plate 112 so as to intermesh with switch gear 12. One end ofa sleeve 120 is disposed upon a forwardly projecting slotted tubular portion 122 of set wheel 116 while the other end of sleeve 120 is disposed upon a rearwardly projecting slotted tubular portion 124 of another set wheel 126 which is rotatably mounted to the rear surface of front plate 10 so as to intermesh with switch gear 12.

Set stem shaft 118 further includes a double keyed portion 128 at the front portion thereof which is of less diameter than the internal diameter of the sleeve and in this manner, set stem 114 may be pushed in or retracted through sleeve 120 such that the keyed portion 128 thereof may selectively engage, in a wellknown manner, the slots provided within the slotted portions 124 and 122, respectively, so as to rotatably actuate gears 12 and 60. A similar actuating mechanism, including a set stem 130, a first set wheel 132 for interengaging switch gear 62, connecting sleeve 134, and a second set wheel 136 for intermeshing with switch gear 14, is of course provided for facilitating the manual setting of clock hands 29 and 63.

Co-axially disposed with and mounted rearwardly of switch gear 16 is an hour wheel 138 which has a forwardly projecting, axial, tubular sleeve member 140, the external diameter of which is less than the internal diameter of sleeve 22 of gear 16 whereby sleeve 140 may be inserted through sleeve 22 so as to project therefrom and thereby serve to rotatably mount an hour hand 142 upon the main clock 37, as seen in FIG. 5, hour wheel 138 itself being engaged with transmission gear pin 190. Furthermore, a minute wheel 144 is coaxially disposed with and mounted rearwardly of hour wheel 138, a forwardly projecting, axially extending, tubular sleeve member 146 thereof being of such diameter as to be capable of insertion through and projection from sleeve member 140 so as to rotatably mount a minute hand 148 upon clock 37. Still further, a second wheel 150 is likewise mounted coaxially with and rearwardly of gear wheels 16, 138, and 144, a forwardly projecting axial staff 152 thereof being of such diameter as to be able to be inserted through and project-from sleeve member 146 whereupon a second hand 154 may be rotatably mounted thereon.

Laterally offset from the time gear assembly comprising gear wheels 16, 138, 144, and 150, is a time set wheel 156 which is freely mounted within front plate 10 by means of an axial staff member 158. A co-axial pinion 160 is secured to the forward portion of staff 158 in front of set wheel 156 for engagement with minute wheel 144, while a rotor-type clamp 162 is disposed upon a rearwardly extending portion of staff 158 and positioned rearwardly of wheel 156, the set wheel 156 itself interengaging a co-axially mounted pinion 164 of second wheel 150. Disposed rearwardly of clamp 162 upon the rearwardly extending portion of axial staff 158 is still another set wheel 166 which is of the same size as set wheel 156. In this manner, then, a set wheel pinion 168 rotatably mounted within rear plate 112 may be actuated by a set stem 170 in a manner similar to that discussed heretofore in connection with set stem mechanisms 114 and 130, whereby minute hand 148, as well as hour hand 142 in conjunction therewith, may be rotated so as to properly set the time indicated upon the main clock 37, through gearing 166, 160 and 144, the forward portion of set stem 170 being mounted within front plate 10 while the rearward portion thereof projects from rear plate 112 as well as rear panel 113 of casing 25, as seen in FIG. 6. Similarly, in order to transmit power from the electric driving motor 172, which is secured to the rear surface of rear plate 112, to the time gear assembly, motor 172 includes an axially disposed pinion 174 which engages an extension gear 176 mounted within rear plate 112 and which includes an elongate pinion gear 178. Gear 178 in turn intermeshes with another extension gear 180 mounted within front plate 10 and which includes a coaxially pinion 182 for intermeshing with second wheel 150.

To complete the manual actuation of the appropriate hands included within the main clock assembly 37, still another set wheel 184, containing a rearwardly projecting coaxial slotted portion 186, is rotatably mounted within front plate 10 so as to intermesh with switch gear 16. A gear 188 is disposed rearwardly of set wheel 184 and includes a forwardly projecting, axial, tubular pinion gear 190 the forward end of which is concentrically disposed about the slotted portion 186 and abuts wheel 184. A sleeve member 192 inserted within pinion 190 so that the forward end thereof is also disposed about slotted portion 186 serves as a guide means for another set stem 194 which projects rearwardly of rear plate 112 and which includes a double-keyed portion 196 for interlocking with slotted portion 186 in a well-known manner, so as to actuate set wheel 184 and consequently, switch gear 16. In a similar manner, gear 188 intermeshes with a pinion 198 coaxially disposed upon minute wheel 144, while the pinion 190 thereof interengages hour wheel 138.

Switch gear 16 is similar to switch gears 12 and 14 for example, in that gear 16 also contains leaf-type cam elements 171 which interengage with arcuate slots 173 provided within hour wheel 138 in a manner similar to the engagement, for example, between cam elements 72 and slot elements 80 of gears 12 and 48, respectively. Hence, in order to control the appropriate switch associated with electrical outlet 3, as seen in FIG. 5, which is controlled by switch gear 16 of main clock 37, there is provided still another finger switch 175 which is pivotably secured to plate 10, by means of a finger switch holder 177 fixedly secured to plate 10, about an axis which extends through the head portion 179 of holder 177 and is parallel to plates 10 and 112. The switch actuating end 181 of switch 175 is spring biased, while the other end 183 thereof is forked so as to encompass the edge portion of hour wheel 138. In this manner, the reciprocal axial movement of hour wheel 138, under the influence of cam elements 171 of gear 16 and the spring biasing means of switch 175 will cause switch 175 to pivot and consequently appropriately actuate the switch associated with electrical outlet 3.

In addition, there is also provided in association with switch gear assembly 16 and main clock 37 a conventional alarm assembly comp-rising a substantially Z- shaped alarm holder and base 185 affixed to front plate 10 which serves to anchor one end of an alarm base 187 by well-known tongue and slot means while the other forked end 189 thereof surroundingly engages sleeve 146 of gear 144. The base 187 is spring biased by means of a coil spring 191, which has one end thereof attached to base 187 while the other end thereof is secured to a stud mounted within front plate 10, such that forked end 189 of base 187 is constantly in contact with hour wheel 138. An elongate, longitudinally reciprocable alarm stop 193 is frictionally mounted within rear plate 112 and contains a pointed tip portion 195 which is also frictionally engaged within an aperture 197 of base 187 whereby base 187 may consequently be actuated by stop 193. Stop 193 also passes through an enlarged aperture 199 which is provided within base 185 for freely securing the forward eend of stop 193. An alarm ring 201, coaxially disposed with motor 172, is interposed between, and in abutting relationship with, the rear surface of rear plate 112 and motor 172 and includes a tongue portion 203 which is inserted within a slot 205 provided within plate 112 so as to secure the ring therein, the end portion of tongue 203 contacting a transversely raised portion 207 of alarm base 187. The time at which the alarm is actuated is of course set by alarm hand 31, the alarm of course being controlled by means of alarm stop 193 in the conventional manner.

Referring now to FIGS. 1 and 3, in order to accomplish the actuation of the hour hand 200 of the clock 202 which is disposed within, and located at the 10 oclock position of the main clock face, as seen in FIG. 5, a gear 204 is rotatably mounted upon a stud 206 of a jump base 208 which is secured to the front plate 10 by means of a dowel 210 at a position such that gear 204 meshes with hour wheel 138. A substantially L- shaped spring member 212 has one end fixedly secured to plate 10 while the other end thereof is fixedly secured to base 208, a dowel 214 serving to also rotatably secure the central portion of the spring to plate 10. Furthermore, ajump switch 216 is rotatably secured within front plate 10 by means of a staff 218 the forward portion of which serves to mount the hour hand 200 while the rear portion of the staff 218 serves to mount a set stem 220 which projects from the rear plate 212 as well as rear panel 113 of clock casing 25 as seen in FIG. 6.

A gear 222 coaxially secured upon staff 218 by means of a lock washer 224 at a position forward of switch 216 but rearward of plate 10, is provided for also engaging gear 204, and a clamp 226 is interposed between gear 222 and switch 216. Switch 216 further includes a'slotted portion, generally indicated by the reference character 228, which comprises a substantially planar portion 230 and an arcuate, camming portion 232, and a spring 234 which is disposed about staff 218 at a position rearwardly of switch 216. In addition, switch 216 also has associated therewith a finger switch assembly comprising a finger jump switch 236 which, along with a substantially L-shaped time cam follower 238, is rotatably mounted within front plate 10 by means of a dowel 240, a sleeve 242 serving to rigidly interconnect switch 236 with follower 238, and a spring 239 connected at one end to switch 236 and at its other end to one of the studs 107 interconnecting plates 10 and 112 serving to bias switch 236 in a direction opposite to that direction which follower 238 normally urges switch 236 when actuated.

Therefore, since clock 202 controls finger switch 236 which in turn controls the appropriate switch connected with electrical outlets 1 and 2 as seen in FIG. 5,

when it is desired to control the electrical power supplied to such outlets, such as for example, outlet 1, set stem 220 is rotated whereby switch 216 and hour hand 200 are rotated'to their respective positions so as to commence a timing cycle. Upon rotation of switch 216, the tip portion 244 of follower 238, which is normally positioned within slotted portion 228 of switch 216 when a previous operative supply cycle of power to outlet 1 has been completed and therefore power to outlet 1 is terminated while power is subsequently supplied to outlet 2, will be forced out of portion 228 by means of cam portion 232. Since finger switch 236 is rigidly connected to follower 238 it will also be moved against the biasing action of spring 239 so as to appropriately operate the switch associated with outlet 1. When however the timing cycle is completed by the passage of time according to the clock movement, follower 238 will have come within the vicinity of slotted portion 228 whereupon it may enter portion 228 under the influence of spring 239 which will'allow finger switch 236 to move to its original position thus again activating the appropriate outlet switch whereby outlet 2 now receives electrical power while power is simultaneously terminated with respect to outlet 1.

Still referring to FIG. 1, the particular electrical switches which are actuated by the numerous finger switches of the present invention for controlling the supply of electrical power to the electrical outlets will now be described in detail. Turning first to those switches associated with electrical outlets 4 and 5, as these switches are identical, only one will be described in detail. The switch includes a substantially L-shaped base plate 246 which is secured to front plate and upon which two dowels 248 and 250 are secured for respectively mounting a gear'252 and a finger gear 254, the forward portion 256 of gear 252 overlapping the rearward portion 258 of gear 254 so as to permit interengagement of the gears, the forked portion 260 surroundingly engaging finger switches 90 and 92, or 98 and 100, as the case may be, so as to be actuated thereby.

Another dowel 262 is mounted withhin gear 252 while still another dowel 264 is mounted within one end of a bucket installation plate 266, the one end of plate 266 being secured to gear 252 by means of dowel 248 while the other end therof is secured to a switch connector, generally indicated by the reference character 268, by means of another dowel 270. While connector 268 is shown as being a one-piece component, it is actually formed from six separate contact elements 261, 263, 265, 267, 269 and 271 secured to a plastic backing member or plate base. A spring 272 is interposed between dowels 262 and 264, while a contact switch 274 is secured to bucket installation plate 266 by means of dowel 270, switch 274 being of such a width for example, so as to be able to bridge or interconnect contact elements 263 and 265, or 267 and 269.

In operation, movement of the appropriate finger switches 90, 92, 98, or 100, will actuate finger gear 254 which will intermesh with gear 252, rotation of which will, by means of spring 272, actuate bucket plate 266 with its switch 274 so as to make electrical contact with the appropriate switch elements 263, 265, 267, and 269, whereby selective control over electrical outlet 4 is achieved. It is of course understood that a similar gear switching mechanism, including another contact switch 275, is also provided so as to control electrical outlet 5, switch 275 also being of such a width as to be able to interconnect contact elements 263 and 261, or 269 and 271.

Turning now to the particular switch associated with electrical outlet 3, an elongate substantially L-shaped base plate 276 is fixedly secured to rear plate 112 while a switch connector 278, which is similar to connector 268 and which comprises separate contact elements 273, 277, and 279, the latter having two contact prongs integrally connected so as to form one contact element, is fixedly secured to plate 276 by means ofa dowel 280. A finger plate 282 includes an elongated portion 284 which is rotatably secured over dowel 280, and a base portion 286 having mounted thereon a spring member 288 for pivotally biasing a click arm 290 relative to base portion 286, arm 290 being mounted upon base portion 286 by means of another dowel 292, and including a camming portion 293. At one end of a bucket installation plate 294 which is rotatably secured by means of dowel 280, there is a small dowel, not shown, which cooperates with click arm camming portion 293 such that when finger switch 175, which is activated under the influence of gears 16 and 138 as noted heretofore and which is inserted through a square-shaped hole 296 within base portion 286, actuates finger plate 282, camming portion 293 of click arm 290 is forced to contact the dowel, now shown, whereupon the apex of portion 293 passes the dowel, not shown, in a first direction.

In this manner, the plate 294, which also has secured thereto, by means of a dowel 297 at the end opposite that end upon which the cooperating dowel is located,

a contact switch 298 for selectively connecting appropriate electronic circuitry associated with switch connector elements 273, 277, and 279, may be actuated about dowel 280 by spring biasing means not shown, so that electric power to outlet 3 is terminated. Under continuing influence of gears 16 and 138, and the respective cam and slot elements, thereof, camming portion 293 will be forced passed the cooperating dowel in a direction opposite to the first direction, whereby plate 294 and its associative contactor 298 will be spring biased in an opposite direction to the initial movement, electrical power to outlet 3 thus being supplied. The entire cyclic operation has a duration of only 1 hour, and therefore when main alarm hand 31 is set at the desired time at which power to outlet 3 is to be terminated, the power will in fact be terminated therefrom for a duration of one hour only, power being automatically supplied in accordance with the operative mode set forth hereinbefore.

In a similar manner, the electrical switch for outlets l and 2 includes a finger plate 300 rotatably secured to base plate 276 by means of still another dowel 302, and another bucket installation plate 304 pivotally secured to plate 300 by a dowel 306 which is mounted within an end portion of plate 300. A spring 308 is interposed between plates 300 and 304, and plate 300 further includes a square-shaped aperture 310 for permitting in sertion therethrough'of finger switch 236, while plate 304 further includes a contact switch 312 which is secured thereon by means of a dowel 314. Switch 312 of course cooperates with a switch connector 316 which is similar to connector 278 and includes contact elements 318, 320, and 322, as shown in FIG. 8, the latter having two prongs integrally connected so as to form one contact element. In operation then, actuation of finger switch 236 serves to actuate finger plate 300 which inturn activates installation plate 304 and its attendant switch 312 whereupon the appropriate switch ing operations take place so as to supply or terminate electrical power to outlets 1 and 2.

Referring now to FIG. 7, the electronic circuitry embodied within the clock of the present invention will now be described. The rear panel 113 is provided with an outlet aperture 324 (See FIG. 6) through which a conventional two-conductor wire 325 leading from a household wall receptacle may be passed so as to be connected to the clock motor 172, and thereby supply electrical power to the clock movement. Associated with the electrical outlets l6 are a plurality of indicator lamps l-6 which are housed within a lamp compartment 326 (See FIG. 6) formed within the bottom portion of the clock housing, the lamps corresponding to the outlets respectively, the particular lamp being lit when the particular outlet is in use. An electrical power line 328, which interconnects the lamps 1-6 as well as the outlets 1-6, is junctioned to main power line 325, while another electrical power line 330, also junctioned to main power line 325 at the clock outlet 324, leads to one terminal of a main outlet power switch 332 which is located atop the clock housing as shown in FIG. 6 and which must be in the closed position for power to be conveyed to any of the outlets. To complete the circuitry between the outlets and indicator lamps, additional electrical lines 334, 336, 338, 340, 342 and 344 are respectively provided.

Still referring to FIG. 7, still another circuit line 346 extends from the other terminal of main power switch 332 to contact element 263 of switch connector 268, as well as contact element 279 of switch connector 278 and contact element 322 of switch connector 316. An additional electrical line 348 is then connected between contact element 265 of connector 268 and line 340 which interconnects outlet 4 and lamp 4, while yet another line 350 interconnects contact element 261 of connector 268 with line 342 which interconnects outlet 5 and lamp 5. Similarly, an electrical line 352 interconnects contact element 271 of connector 268 with line 344 associated with outlet 6 and lamp 6, while electrical line 354 interconnects contact element 267 of connector 268 with contact element 277 of connector 278. Contact element 269 of connector 268 does not have an electrical line associated therewith for a purpose to become apparent hereinafter. An electrical line 356 interconnects contact element 273 of connector 278 with line 338 associated with outlet 3 and lamp 3, while electrical lines 358 and 360 interconnect contact elements 318 and 320 of connector 316, with lines 334 and 336, associated with outlets and lamps 1 and 2, respectively.

In operation then, upon closing switch 332, power is supplied to each of the connectors 268, 278, and 316 by means of contact elements 263, 279, and 322, respectively, and each of the connectors have associated therewith contact switches 274 and 275, 298 and 312, respectively. Hence, when, for example, switch 312 is actuated so as to bridge contact elements 322 and 318, power may be transmitted to outlet 1 and the appliance or device assocaited therewith. In a similar manner, when switch 312 is actuated so as to bridge contact elements 322 and 320, power is transmitted to outlet 2. In this manner, it may thus be seen that outlets 1 and 2 operate alternatively with a duration of 5 minutes to 12 hours, as indicated by hand 200 of clock 202which is of course set with the main clock 37, although such could also be adapted to have a duration of 24 hours. Outlet 1 is thus supplied with power by manually setting a time upon clock 202, during which time preceding the set time outlet 1 will be supplied with power and at which time power to outlet 1 will be automatically terminated and power to outlet 2 automatically supplied. Power to outlet 2 continues to be supplied until a new cycle for power to outlet 1 is commenced by setting hand 200.

Likewise, actuation of switch 298 such that contact elements 279 and 273 are bridged permits power to be supplied to outlet 3 while actuation of switch 298 to a position wherein contact elements 279 and 277 are bridged results in outlet 3 being by-passed with respect to reception of electrical power. With respect to supplying electrical power to outlets 4, 5, and 6, actuation of switch 274 to a position wherein contact elements 263 and 265 are interconnected results in electrical power being supplied to outlet 4, while positioning switch 275 so as to interconnect contact elements 263 and 261 permits power to be supplied to outlet 5. As discussed heretofore, power to outlets 4 and 5 is controlled automatically both for the ON and OFF modes, the green hands 27 and 29 indicating the respective times at which power will be terminated to the particular outlet, while the red hands 61 and 63 respectively indicate the times at which power will be supplied to the outlets. The time hands 47 and 49 are of course set with the main clock 37, and as each of the clocks 33 and 35 are 24, clocks, any one of the hands 27, 29, 61 and 63 can be set for any one of the 24 hours, the ON hands 61 and 63 being capable of being set to a time which differs from the current time, as indicated by hands 47 and 49 or hands 142, and 148, by as little as fifteen minutes, in which case the respective OFF hands 27 and 29 must be set for a time at least 1 hour later.

Appreciation of the circuitry discussed heretofore will make it apparent that to supply power to outlet 6, power cannot be supplied to any one of the outlets 3, 4, and 5. This is seen to be the case because in the instance power is supplied to outlet 3 while not being supplied to outlets 4 and 5, power transmitted to contact element 263 cannot reach contact element 271 to which outlet 6 is connected, due to the fact that neither switch 274 not switch 275 is interconnected to element 263, but are in fact interconnected between elements 267 and 269, and 269 and 271, respectively. It is true that element 267 is interconnected with element 277 of connector 278, but since outlet 3 is being supplied with power, switch 298 interconnects elements 279 and 273, thus not permitting power to be transmitted to element 277 and consequently no power is trans mitted to element 267.

In the instance that power is supplied to outlet 4 only, power is able to be transmitted to element 267 via elements 279 and 277, however element 267 is in no way connected to element 271 associated with outlet 6 for switch 274 interconnects elements 263 and 265, while switch 275 interconnects elements 269 and 271. The reverse situation would also be relatively the same, for when power is supplied to outlet 5 only, power is conducted through elements 263 and 261 by means of switch 275, but the power transmitted to element 267 is still not able to be transmitted to element 271 as switch 274 connects 267 and 269, the latter not being connected to any other contact or line.

When however, power is not supplied to any one or more of the outlets 3, 4, and 5, power transmitted to element 279 is conducted through switch 298 and element 277, transmitted through line 354 to element 267, and since switch 274 and 275 interconnect elements 267 and 269, and 269 and 271, respectively, power is able to be supplied to element 271 and consequently to outlet 6 which similar to outlet 2, is thus automatically supplied with power. It will be appreciated further that power to outlet 6 is thus time-controlled not by any one clock directly as is the case with the other electrical outlets, but to the contrary, is controlled indirectly through direct time-control of power to outlets 3, 4, or 5.

Furthermore, in order to provide for still other electrical interconnections and switching operations, additional toggle-type switches 362 and 364 may be respectively provided so as to interconnect outlets 3 and 4, by means of electrical line 363 being interposed between lines 338 and 348, and outlets 4 and 5 by means of electrical line 365 interposed between lines 363 and 350, switches 362 and 364 being conveniently located upon the right and left sides of rear panel 113, as seen in FIG. 6. Consequently, if switch 362 is in its closed position, any appliance or device connected to outlets 3 and 4 can be automatically turned ON and OFF twice by setting the proper times upon clocks 37 and 33 just once, because although the particular individual switch, such as for example, 298 and 274, associated respectively with outlets 3 and 4, may be in the position whereby power is not supplied to one of these outlets, power may nevertheless be supplied thereto through the bypass created by switch 362 and line 354, and the other switch associated with the other outlet. As can be seen still further, if switch 364 is also in its closed position, any appliance connected to outlets 3, 4, and 5 can be automatically turned ON and OFF three times by setting the proper times upon clocks 37, 33 and 35 just once because an additional power by-pass has been created.

Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is to be understood therefore that within the scope of the appended claims the present invention may be practiced otherwise than as specifically described herein.
