IMPROVEMENT IN LOCKS FOR DOORS, &c.
Specification forming part of Letters Patent No. 183,738, dated October 24, 1876; application tiled June 20, 1876.
specification Figure l 1s a sectional elevation of our improved lock, and the door to which it is applied. Fig. 2 is a front elevation of the lock. Fig'. 3 is a perspective view of the tumbler. Fig. 4 is a view of the key, and Fig. 5 is a rear elevation ot' the bolt.
Similar letters of reference indicate corresponding` parts.
Our invention relates to improvements in locks which are particularly applicable to letter-boxes; and it consists in the combination of the several parts of the lock, as will be hereinafter more fully set forth.
In the accompanying drawings, K is the door of a letter-box, to which our improved lock is shown attached. J is the recess in the door for receiving the lock-case P, provided with an openin gat its upper end for the passage ofthe end of the bolt. Ais the bolt, provided with the yoke A', having an opening, d, and inwardly-projecting ends b b, recessed on their rear faces at a c. a is a recess near the lower end of the yoke, on its rear face, which receives the spring Fin the downward movement of the bolt. vo o are horizontal lugs,se curely attached to the inner face of the lockcase, which embrace the rounded upper portion of the bolt, and guide it in its reciproca tions. n is a plate, securely attached to the upper faces ot the lugs o o, and bridging the space between them. The plate n serves as a seat for vthe coiled spring B, surrounding the upper end of the bolt, the tension of the sprin g being exerted to lock the bolt. C is the tumbler, the projecting rear end of which passes into a perforation in the back plate of the lock-case, the tumbler operating in the opening d in the yoke A of the bolt. I is a keybarrel, provided with a slot, G, which is prolonged through the lower front part of the tumbler, to receive the projecting end of the spring AF, which prevents the tumbler from turning. D is a follower in the lower part of the key-barrel 1, and E represents a coiled spring for throwing out the key. The upper part of the tumbler is curved, and provided with recesses m m and flanges c c, the recesses receiving the inwardly-projecting ends b b of the yoke A ofthe bolt. H (see Fig. 4) is the key by means of which the projecting end of the spring F is pressed down and out ot' the slot G in the tumbler, when the latter may be turned and the bolt operated. S is a spring, attached to the lower partof the lock-case, and pressing against the lower face ofthe yoke A', so that when the downward pressure of the tumbler on the bolt is removed the bolt will be sprung into a locked position.
What we claim as new, and desire to secure by Letters Patent, is
The bolt A, provided with the yoke A', having opening d and inwardly-proiecting ends b b, recessed at a c, in combination with the tumbler O, having the recesses ml m, flanges c c, slot G, and key-barrel I, and the springs B S F, substantially as described, and for the purpose set fortn.
