Claims.
This invention relates to electric locks of the type having a central control system.
It is the object of my invention to devise a lock having a bolt, the retraction of which is elec- 5 trically controlled, so that the bolts of a series of locks may be operated or prevented from operation by some central system. In general, my lock is intended for use in the system disclosed in an application filed by W. E. Goehring on January 9, 1930, No. 419,652.
For one modification of my invention, I refer to the drawings, wherein Fig. 1 is a front view of my invention. Fig. 2 is a front view of my lock showing the cover plate removed. Fig. 3 is a view along the line 3-3 of Fig. 2. Fig. 4 is a view along the line 44 of Fig. 2. Fig. 5 is a view along the line 5-5 of Fig. 4. Fig. 6 is a view of a portion of Fig. 5, showing the armature in one of its positions. Figs. 7 and 8 are 20 views showing the adaptation of my invention to a combination lock.
Referring now more particularly to the drawings, Fig. 1 shows a lock 10 having a bolt 11 operable by a handle 12 in the usual way. It should be understood that the handle 12 may instead be a key operated cam or other bolt retracting means. The bolt 11 is spring pressed in an outward looking direction by the springs 12a and has a suitable cam section 13 which may be actuated by a roll-back 14 to retract the bolt. This roll-back is of course operable by the handle 12 or any other means desired.
As shown in Fig. 2, the bolt 11 has a rearward extension 15 behind which is adapted to rest a dog 16. This dog 16 constitutes the armature for an electro-magnet 1'7, and it will be readily understood that when this electro-magnet 17 is actuated by the closing of its circuit, it will attract the armature 16 and hold the same in the positon of Fig. 6, wherein it will be out of interfering position as regards the extension 15 of the bolt 11, and will permit the withdrawal of that bolt.
The circuit for the electromagnet 17 is located partially within the lock, and partially outside of the lock. For the purposes of explaining this invention, it is needless to go into the external circuit, which may be controlled by various means not constituting part of this invention. The internal portion of the circuit is controlled by series of switch contacts 18 which are adapted to be moved into closed relation so as to close the circuit through the electro-magnet 17. This bringing of the contacts into closed relation is accomplished by means of the exten- 1930, Serial No. 475,657
It will be readily understood that attempted retraction of the bolt 11 by the cam 14 will permit rearward movement of the bolt and its extension 15 until stopped by the dog or armature detent 16. If the external circuit through the electro-magnet 17 is closed, then attempted retraction of the bolt 11, acts through the extention 15 to tilt the lever 19 about its pivot 20, so as to close the circuit through the switch 18. This action takes place before the extension 15 is stopped by the dog 16. As will be readily understood, the closing of the circuit through the electro-magnet 17 will act to remove the dog 16 from obstructing position relative to the extension 1.5 and further retraction of the bolt will be possible.
Referring now to Figs. 7 and 8, I show a modification of my invention as applied to a combination lock, employing the usual type of rotary tumblers 22. As is quite evident, I use a bolt 11, a magnet 17, and a dog 16 operating in the same relation as in the previous modification.
For retracting the bolt 11, I employ a retracting lever 21 and a series of rotary combination tumblers 22 of the usual type operable on a shaft 23. For controlling the bolt retracting member 21, and operating the same in a retracting direction, I utilize a cam 24, also mounted on the shaft 23. As will be obvious to one skilled in the art, the setting of the tumblers 22 acts to drop the lever 21 into the notch 24 of the retracting device 24. This is only possible, however, if the dog 16 is removed from its position of Fig. '7 to its position of Fig. 8, since otherwise the dog 16 will support the lever 21 in its position of Fig. 7. This removal of the dog 16 is accomplished, as is readily understood, by the closing of the circuit of the electromagnet 17. The closing of this circuit is accomplished by the retracting device 24 which, as soon as it is rotated from its position of Fig. 7, acts upon a cam 26 to close the series of switching devices of the circuit through the magnet 17, as will be readily understood.
While I have shown two modifications of my invention, it should be understood that variations of the same within the scope of the appended claims will be apparent to one skilled in the art.
I claim:
1. In a look, a series of rotary combination tumblers, a bolt adapted to be withdrawn when said tumblers are properly operated, a detent for preventing retraction of said bolt, an electrotric magnet controlling said detent, and meanson said bolt adapted to close the circuit at one point upon slight retraction of the bolt whereby to actuate said detent out of obstructing position to allow full retraction of said bolt.
3. In a lock, a series of rotatable combination tumblers having gatings, a lever member adapted to drop into said gatings when the tumblers are properly positioned with the gatings aligned, a detent adapted to obstruct movement of the lever member into the gatings, and electro-magnetic means operable to withdraw said detent from obstructing position.
4. In a lock, a series of rotary combination tumblers having gatings, a lever member adapted to drop into said gatings when the tumblers are properly positioned with the gatings aligned, a detent for preventing movement of said lever member into the gatings, an electro-magnet for moving said detent out of obstructing position, a circuit through said magnet and a switch for said circuit, and means for closing said switch operable upon rotation of said tumblers.
5. In a look, a series of rotatable combination tumblers having gatings, a lever member adapted to drop into said gatings when the tumblers are properly positioned with the gatings aligned, a detent adapted to obstruct movement of the lever member into the gatings, electro-magnetic means operable to withdraw said detent from obstructing position, and means for closing a circuit through said electro-magnetic means when said tumblers are rotated.
