LOCK.
SPECIFICATION forming' ence beiughad to the accompanying drawings,
which form a part of this specication.
Figure 1 is a perspective view, showing my improved lock open, the covering-plate having been removed so asto expose the working parts. Fig. 2 is a 4plan view, showing the lock closed; and Fig. 3 is a similar view, showing the key in position for opening the lock.
Corresponding parts in the several figures are denoted by like lettersof reference.
This invention relates to locks; and it consists in certain improvements in the construction of the same, which will `be hereinafter fully described, and particularly pointed out in the claim.
In the drawings hereto annexed, A represents the frame or casing of the lock, of which B is the main or base plate.
O is the tumbler, which is provided at its lower or inner end with a slot, D, tting over a guide-stud, E. Its upper or outer end forms the bolt F, which projects in the usual manner through a slot in the rim of the casing. The tumbler O has at its upper or outer enda shoulder, Gr, which receives the pressure of a spring, H, by which the tumbler is forced outward to close the lock. Near its inner end it has a notehor shoulder, I, to engage a spring detent, J, by which the tumbler may be held retracted, thus leaving the lock open.
Pivoted upon the tumblerplate O is a cam, K, one side of which is curved 0r rounded, as at L, its other side being` provided Vwith an arm, M, having a notch, N. lIhe cam K is retained in its normal position' by a suitablypart of Letters 4Patent No. 257,995, dated May 16, 1882. Application filed March 15, 1882. (Model.)
shaped spring, O, secured to the tumbler and bearing against the curved side of the cam.
The operation is as follows: To close the lock the key is inserted and turned from right to left. The bit will thus bear against the under side of the cam-arm M, and turn the cam against the tension of spring O, forcing the latteroutward until it bears againstthe springdetent J, throwing the latter out of engagement with the shoulder I ofthe tumbler,which,
being thus released, is forced outward by the action of the spring H, thus closing the lock. To open the lock the key must be turned from right to left until the bit engages the notch N in arm M of the cam, care being taken not to turnlthe key too far, in which event the cam- 6o arm will be entirely passed, making it necessary to turn the key back to the starting-point. When the bit of the key engages the notch N the key is to be turned to the right, thus forcing the tumbler back until it is retained by the detent lJ.
My improved lock is simpleinexpensive, and durable, and it cannot readilybe opened by those not familiar with the secret of its manipulation.
7o I am aware of the patent to Spathelf, No.
80,369, July 28,1868, and I do not claim the construction therein shown.
Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesy The combination of the tumbler having shoulders Gr I, cam K, having curved side L, and arm M, provided with notch N and spring O, the spring H, and the detent J, all arranged 8o and operating substantially as set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
ELI ANDERSON.
