ALPHONS LEMKE, ()F ASOHAFFENBURG, BAVARIA.
LOCK.
SPECIFICATION forming part of Letters Patent No. 234,592, dated November 16, 1880.
Application filed November 20, 1877. Patented in France September 11, 1877, in Italy October 25, 1877, in England September 17, 1877, and in Germany August 26, 1877.
To all whom it may concern:
Be it known that I, ALPnoNs LEMKE, of Aschaffenburg, in the Kingdom of Bavaria, German Empire, have invented certain Improvements in Door-Locks, of which the following is a specification.
The present invention has reference to that class of locks in which the opening operation is effected by electromagnetism or air-pressure; and the invention consists in the construction and combination of parts which will be hereinafter more fully explained and claimed, so as to enable others skilled in the art to make and use the same.
In the accompanying drawings, forming part of this specification, Figures 1 and 2 are face views of a lock having electro magnets and armature, and representing the latchbolt, respectively, in a projected and retracted position. Figs. 3 and 4 are similar views, showing a modification in which a flexible air bulb or sack is used for opening the lock.
As shown in Figs. 1 to 4, inclusive, the sliding latch-bolt A is retracted or drawn back into the lock -casing by means of a doublearmed or centrally-pivoted lever, B, having its lower arm connected with a coiled spring, 0, which serves to throw the lower arm of the lever to the left and the upper arm to the right for projecting the latch-bolt into the door-frame or lock-strike.
When the bolt A is in a projected position the lower arm of the lever B engages with the hub D of a trigger, at, said hub being provided with a locking shoulder or projection, I), for this purpose. The upper end of the lever is retained by means of a doublearmed lever, F F, the arm F of :which serves as an armature, which is attracted by the electro-magnets when the electric current is passing through the same.
The movement of the armature-lever is regulated or defined by means of a set-screw, f, and a spring, g, serves to withdraw it from the magnets.
As shown in Fig. l, the lock is represented in a locked position. In order t retract the bolt a current of electricity is made to p through the magnets, which then attract the armature F, and the arm F is released from engagement with the trigger-arm d. Consequently the spring 0 operates the lever B and throws the latch bolt back, also throwing forward at the same time a second bolt, K, having an inclined nose or front face, said bolt serving to open the door. This result is effected by causing the said bolt K, as it is thrown forward, to engage with an inclined projection, is, of the lockstrike, or a plate applied to the door-frame.
The bolt-K also has for its object to set the mechanism when the door is shut. As the bolt K strikes the door-frame or look strike the spring-tongue t of-said bolt bears against the projection 'i of the lever B and presses the same back, so as to cause its lower end to engage with the shouldered hub D of the trigger-arm d. This operation will cause said trigger to engage with the armature or looking-lever F F, for maintaining the latch-bolt A in a projected position. A coiled spring, K having an arm, serves to throw the bolt K forward when it is released from the lever mechanism.
The latch-bolt can also be operated independently of the mechanism heretofore described by means of a lever, M, and an elbowarm, L. The former is moved by the key, which serves to operate the ordinary lock-bolt, and the elbow-arm is connected with the ordinary knob-spindle.
Instead of the electro magnets and armature, 1 also propose to use a flexible a-ir bulb or bag, H, which is applied to a supportingplate carrying a spring-pressed lever, F The latter engages with the trigger-arm in the same manner and for the same purpose as the armature-lever.
The air-bag, when inflated by means of a suitable air-tube, will serve to turn the lever F thus releasing the trigger and the lever mechanism from the latch-bolt and throwing the same back.
Having thus described my invention, what I claim as new, and desire to secure by Lette Patent, is-- The pivoted lever B, having projection i, spring 0, trigger (I, provided with hub D and shoulder I), and double-armed lever for locking and releasing the trigger, in combination with electro-magnets or an equivalent releasin g device, latch-bolt A, and bolt K, substantially as herein set forth.
i In testimony whereof I have signed my nznne to this specification in the presence of two subscribing witnesses.
