A further object of the invention is to.
l provide an auxiliary switch in said electriccircuit for opening and closing the circuit in an open position of the main-switch.
A stillsfurther object of the inventlon 1s to lprovide an auxiliary switch of such a 2 character as to permit of its actuation, either designedly or accidentally, to close the electric circuit from a point remote from the switch.
Other and more specific objects of the invention will be apparent from the following description and claims.
In a preferred embodiment of the present invention, an ordinary type of alarm-clock is emploved to at a predetermined time actuate a switch to successively close and open an electric-lamp circuit whereby to first intermittently flash a light a plurality of times and thereafter. provide a constant light.
The alarm-clock is preferably sustained by an insulated base provided with two pairs of spaced contact-members constituting the stationary elements of main and auxiliary electric-circuit controlling switches. Projecting upwardly above the base and d1sposed between each pair of the stationary f contact-members is a guide-post for a vertically shiftable tube of some insulating ma- Vterial such as porcelain, eachtube 'carrying at its lower end an electric-current conduct ing element adapted in the lowered position ofthe tube' to bridge the stationary conta'ctlowered or circuit-closing position. The two palrs of statlonary contact-members are so connected with an electric-lamp circuit that t either switch may be employed to close the circuit in an open position Aof the other switch. Consequently the auxiliary switch may be employed to close the circuit to light the lamp While the clock alarm-stem is set to hold the main-switch open. The tube of the auxiliary'switch carries a lateral arm which in'an open positon of said switch overlies an angular rest-rod projecting upwardly from the supporting-base. Surrounding said lateral arm is a ring connected to a cord which may obviously be manipulated from a point remote from the switch toclose the circuit and light the lamp, said ring being free to slide off the lateral arm upon manipulation of the cord.
In the-accompanying drawings, Fig. 1 is a rear elevation, with the supporting-base in longitudinal section, of the present improved light-controlling,device. Fig. 2 is a top plan view of thel same, with the alarm-clock casing partly in section. Fig. 3 is a sectional view substantially on the line 1-1 of Fig. 1. Fig. 4 is a detail sectional view of a modified supporting base and showing a diierent form of construction of stationary cont-actmefmbers. Fig. 5 is a top plan view of the modification, showing the supporting-post in section.
Referring to the drawings, a supporting base 1 of some suitable insulating material constitutes the upper plate of a casing of any desired form or outline, being in the present instance shown as rectangular. Preferably rigidly secured upon the base 1 is an electric-lamp 2 having two current-lead connections, as 3 andV 4, of which the current-lead 3 extends from a suitable current- Asupply source through a casing-bushing 5.
The supporting-base 1 is provided with spaced apertures, as 6 and 7 underlying which is a stationary contact-member carrying plate 8 of insulating material secured to the under side of the base 1 by screws as 9;
Secured upon the upper face ofthe plate 8 by current-transmitting screw-bolts, as 10, are the Shanks of vstationary contact-members 11, 12l and 13 bent upwardlyand partly backwardl to form spaced inclined projections within the apertures 6 and 7, the contact-member 12 being common to both apentures. The lamp current-lead 4 is connected to the bolt of contact-member 11 which is'in evident that the descri mit a transmission of current to the lamp 2 28 surroundin turn connected b means of a current-lead 14 to the bolt ot contact-member 13. The contact-member 12 is similarly connected to a return lead 15 which passes through the bushing 5 to the supply source. It will be ed connections per- .17, slidingly and rotatively guiding the tubes 18 and 19 of porcelain or othersuitable. material, the lower ends of which tubes are' provided with the shiftable contactmembers 2O and 21. Adjustably clamped l .upon the tube 18 is a laterally extending arm 22 havin a downwardly curved free end and whlc arm is connected by means of a lring 23 with the offset free end of a lever 24 pivotally supported upon the usual alarmsetting stem 25 provided on the rear face of an ordinary type of alarm-clock 26. The
alarm-clock 26 is sustained by the base 1 and is preferably held clamped in operative positron by means of a. cleat 27 engaging the 'i vflanged rear end of the clock-casing.
The lever 24 is provided with a' cam-slot the alarm-winding stem 29 which rotates 1n a direction reversely of the winding direction upon being released at a gredetermined time by the clock-mechanism. ecured upon said stem 29' for rotation i therewith is adisk 30 carrying -a radially o'set. stud-screw 31 comprising a crankmember adapted to engage the upper wall of the cam-slot 28. In operation, the clockalarm. is wound and set as usual, but the winding of the alarm is preferably terminated at a point wherein the screw 31 occu- Q pies its limit of upper movement. whereby the engagement of said screw with. the lever y24-causes the shiftable contact-member 20 to raise the tube whereu 'A as beheld in raised or switch-open position.
AtV the predetermined time, the stem 29 com- `mences to rotate causing the lever 24 to vibrate and permitting the tube 18 to gravita.- tionally descend to close the electric-circuit connections with the lamp 2. In the continued rotation of the stem 29, the tube 18 is again lifted, which o eration is repeated urality of times t ereby causing the a ligiit to flash intermittently. The weight of the tube 18 is such that as the alarm-spring becomes unwound it is finally too weak to n the actuating mechanism comes,to rest 1n switch-closed position.
The `tube 19 and its contact-member 21 comprise a shiftable switch-member auxiliary to l,the main switch 2O and has for its prime function to provide for closing the -the raised or switch-open llamp-circuit in the open position of the switch 20, so that the light of the lamp 2 may be employed to set the device for operating the switch-element 20. The tube 19 adjustably carries alateral arm 32 which in osition of said tube may be caused to overlie the horizontal portion 33 of a bent rest-rod 34 suitably secured upon the-base 1. In order to provide for releasingthe arm 32 from the rod 34 from a point remote from the device, the arm 32 is loosely surrounded by a ring 35 connected to a cord 36. The cord 36 may also, if desired, be so positioned as to cause detection of an unauthorized intrusion upon the premises, as willibe self-evident.
In Figs. 4 and 5 is shown a modified form of 'constructiomfor the stationary contactmembers. A supporting base 37 is dished on its under surface and 'is provided on its upper side with a circular recess 38 which at diametrically opposite points merges into small segmental recesses, as 39 in each of which is dispo:ed a portlon of a rounded head 4() of a bolt 41 suitably secured upon the base 37 to connect current. leads therewith. The bolt-heads 40 in this instance constitute a pair -of spaced stationary contact-members adapted to be bridged by a movable contact-member guided by a post 42 also secured upon the base 37 medially of said bolt-heads.
