. l l SEQUENTIAL SIGNAL PRODUCING MEANS I BACKGROUND OF THE INVENTION There has longbeen a need for an easily operated actuator for. controlling electrically operated locks used with'safes, doors, and the like. An example of such a need would be in high security office buildings, wherein the doors to high security areas are kept locked by elec- I trical sequential signal controlled locks, except when the doors are opened to permit passage of personnel, and then upon closing, the doors are relockecl. The personnel who have access to these high security areas, will pass through these door's many times a day-and each time must unlock the door; To ease the burden of unlocking such doors, key or card actuators are used, but-these actuators are not particularly secure as the key or card can be forcibly or otherwise taken from an authorized person. f I I A combination actuator is not subject to such a theft,
for the key is kept in the mind of the authorized personnel. However, the heretofore'used mechanical combination actuators have been subject to being picked by feeling the tumblers drop, hearing the tumblers drop or by disassembling the lock to observe the wear pattern or tumbler opening locations. A combination actuator for use in a high security area should not be able to be picked by any of the above techniques.
' BRIEF DESCRIPTION OF THE INVENTION It is therefore the primary object of this invention to disclose and provide anovel actuator imeans for producing a sequential electronic signal which can not be picked by heretofore known method s, which cannot be discovered by merely disassembling the lock and which can be operated only on a preselected number Other and additional objects of this invention are to provide such a means which can be opened by combination but which gives no indication of what the combination is, and which will, upon being manipulated to other than the proper combinatiomprovide a warning that the means is been tampered with, to provide such a means which can be operated by a patterned member such as a card, to provide such a meanswhich can be completely removed and yet will not indicate the com bination or produce the sequential signal, to provide such a means which is economical to produce, easy to install, easy to operate and virtually impossible foran unauthorized person to open. I
Generally the means for generating a preselected sequential signal to be sentto a means for discriminately receiving a sequential signal includes a. manually movable actuator control means for movement between distinctive positions and for association with a housing having sensing means mounted thereto for sensing respective distinct positions of the actuator moving in one mode between distinct positions and in the other mode between a non-aligned position outof may include meansfor sensing the presence of a properly patterned member and for producing the preselected sequential signal in response thereto.
The housing may include a cover and a two portion back wall. The sensing means may include a source of energy, such as a light, and receivers of energy, such as photoelectric cells, with the actuator control means including a dialmember witha single energy path such as a port therethrough. A guide means may be provided to insure the location of the control means in one of the distinct positions, to prevent movement of the control means in the aligned position in the one mode, and to cammingly move the control means to the non-aligned position upon attempted movement thereof in the one mode in the aligned position. Biasing means may be provided for biasing the control means to the nonaligned position. Illuminating means may be provided for illuminating the indicia on the control means.

The guide means is completed ,by the provision of a skirt 68 on the knob 57 which extends into an annular groove 69 around the aperture 61 to hide the ratchet teeth 66 67 and thereby prevent dirt or other contaminants fromiodging therebetween.
As best seen by comparing FIGSQI! and 5, upon movement of the dial member 51 from the non-aligned position to the aligned position, the ratchet teeth 67 will move rearwardly with the knob .57 into engagemerit with the ratchet teeth 66, to rotate the dial member 51, if required, slightly, until the ratchet teeth mate, as shown as in FIG. 6.

All other persons who are permitted to enter the area, would use the combination portion 29, thereby keeping the possibility of theft of the card to a minimum. I I
As-best seen in FIGS. 1 and 3, the sensing means85 includes a slot 86 in the lower portion of a front wall 21 suitable for the passage of a properly patterned card to the interior of the housing 15. The member presence sensing means 85 includes'a source 87 of energy which in the preferred embodiment is a light 88 mounted in a reflector member 89 having reflective surfaces 90 f .whichreflect the lightrays from the light87, in a multiplicity of distinct vertical paths. The reflector member of the back wall l6 be'low theilocation of the slot 86. I As bestseen in FIGS. 3 and 7, the receiver 91 of the sensing means 85 for receiving energy from the source '87 includes a plurality of photo-electric cells 92 mounted in holes 93 in a forwardly protruding ledge 94 of the lowerportion 18 of the back wall 16. A card receiving space 95 separates the receiver 91 from the either'be operated by rotating of the dial member 51 to preselected distinct positions and sliding the dial member 51 'to the aligned position in the proper combination of steps or can be operated by the insertion of a properly patterned card. In either event, some or all of the photoelectric cells, not in the preselected positions, .could be attached toan alarm system, so that anyone not knowing thecombinationor not having the proper card, will sound an alarm. This will help prevent random discovery of the patter required to operate the means 10.
Another advantage of the construction accordingto this invention, is shown in FIGS. 8 and 9. If extreme security requirements dictate the provision of the means 10 with only the combination portion 29, a cover 20 is provided which mounts only the upper portion 17 of the back wall 16 utilizing the sensing means 30, actuator control means 50, mounting means 60, guide means 65, biasing means 70, illuminating means 75, and energizing means 80 without any changes in the construction of these means.
Likewise, the means 10 may be provided only with the member presence sensing means 85 only. In such a construction, the lower portion 18 of the back wall 16 is combined with a cover 20 of a slightly smallersize and which has a slot 86 in the front wall 21 thereof with the energizing means 80, the source 87, and the receivers- 91 all being of identical construction to that used in the combined means 10;
In the preferred'embodiment, the sensing means 30 include a light32- and photo-electric cells 41 with the dial member 51 of the control means 50 selectively passing light rays therebetween to generate the preselectedsequential signal. It is certainly within the contemplation of this invention to use other types of sensing means 30 and control means 50 such as, for example, mechanical elements or electrical switches closed or opened by" the two mode suitable control means 30.
