LOCK.
SPECIFICATION forming part of Letters Patent No. 416,467, dated December 3, 1889.
Application led April 19, 1889.
To all whom it may concern:
Be it known that I, CHARLES L. LINCOLN, of Stamford, county of Fairiield, and State of Connecticut, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had to the accompanying drawings.
My invention relates to that class of locks in which the bolt is actuated by the cam on the inside of the plug of an ordinary pin-turnbler lock.
The object of myinvent-ion is to provide in such a lock an improved connection between the cam of the pin-tumbler lock and the bolt and improved means for dead-locking the bolt in the cast and retracted positions, respectively. Heretofore in locks of this description the connection between the cam and the bolt has been direct-as, for instance, in the lock shown in the patent to Taylor, No. 381,293. In this lock, for example, the bolt is held in the locked or unlocked position by a spring-lever, and the cam has to pass the bolt, depress the lever, and then strike the bolt to cast or retract it. rIhis requires exceedingly close adjustment between the cam and the bolt, for if the former should be too long it would altogether fail to operate the latter. If it were too short, and an attempt should be made to retract the bolt when it was binding, the end of the cam would jump over the tail of the bolt, and the bolt would be effectually locked out, because the cam could not be turned around again. To obviate this difficulty I provide upon the bolta pivotally-movable arm, against which the cam impinges, and which enables it to move the bolt, but slips aside to allow it to pass clear as soon as the bolt has been completely cast or retracted.
In the accompanying drawings, Figure 1 is a plan view of my improved lock, showing the bolt in the unlocked position. Fig. 2 is a similar view showing the bolt in the locked po-l sition, and Fig. 3 is a section on the line 3 3 of Fig. 2.
The lock is generally applied in practice in the reversed position from that shown in the drawings-that `is to say, the main bolt is commonly at the bottom and the pin-tumbler lock at the top; but of course it will work equally Well in either position.
serial No. 307,673. (No model.)
Referring to the letters on the drawings, A indicates the lock-case, and B its cap. Upon one side of the case is an ordinary pin-tunibler lock C, which is provided with tumblers and key-plug of Well-known construction. (Not illustrated.) Upon the inner end of the said key-plug is secured in the ordinary way a cam F.
G indicates a bolt provided with a guiderecess II, adapted to receive the guide-pin I, which projects from the case.
.I indicates a double detent or catch, and K an arm secured by the pivot-pin L to the tail of the bolt. The arm K is provided with the rounded projection M, which in use bears against the detent J to operate it.
N indicates a springsecured to the bolt by the pins O, which, passing through the slot P of the arm K, bears against the pin Q therein.
R indicates a spring secured at one end to the bolt by the pins O, and Which at the other bears against the. detent .I to somewhat restrain its Vibratory motion.
S indicates an oblong projection extending from the case A, and provided with beveled ends, one of which one or the other end of the detent J embraces, according as the bolt is cast or retracted.
The operation of my look is as follows: The bolt being cast, the cam F, being rotated toward the right by means of its key and keyplug, strikes against the arm K. It in turn advances the projection M against the rearward end of the detent and releases its forward end from the projection S. Continuing to push against the arm, the cam retracts the bolt. As soon as the bolt has been fully re` tracted the continued rotation of the cam pushes the arm K aside and causes the rearward catch of the detent to embrace the projection S, allowingthe cam to pass clear. At the same time the spring N causes the arm K to assume a perpendicular position, so that it is ready to be operated by the rotation in the opposite direction of the cam, upon which the bolt is again released, cast, and locked in a manner corresponding to that of retracting it just described.
From the foregoing it will appear that the length of the cam may vary considerably, and yet an operative connection between it and IOO the bolt With certainty be maintained. I therefore avoid the expense of manufacture which the nice adjustment heretofore required necessitated. I also produce a lock which is absolutely free from possibilit-y of locking` out, which is a serious difficulty in other locks of this description.
What I claim, and desire to secure by Letters Patent of the United Sta-tes, is-
l. In a lock, the combination, with the case, of the bolt, an arm and a catch pivotally secured thereto, and means adapted to simultaneously operate Jthe catch and communicate motion through the arm to the bolt, substantially as described.
2. In a lock, the combination, with the case,
