IMPROVEMENT IN CARRIAGE-DOOR LOCKS.

Specification forming part of Letters Patent No. 197,215, dated November 20, 1877 application filed September 28, 1877.

To all whom 'it may concern Be it known that I, ,TosIAs D. Goon, of Mount Joy, inthe county of Lancaster and I State of Pennsylvania, have invented certain ters of reference marked thereon, and a brief 1 description, will enable those skilled in the art In the drawings, Figure 1 is a perspective view of the, several parts detached. Fig. 2 shows the plan of the interior and arrangement of the parts. i

This lock or latch is to be set into a mortise so asto bring the selvage or edge plate at flush with the wood on the edge of the oor.

The'bolt and its operation are as in other locks and latches. It is operated withaturning knob or handle inserted into the tumbler F, so that its lever-arm f, prolonged on one side of the circular central enlargement, forms shoulders, against which the upper and lower plates 0 D set and confine it. in its turning motion. This lever-arm f strikes the pendent arm eof the bolt E, in order to press it back against the spring K to release it from the catch-plate H, ioopen the door in the ordinary manner.

The novelty of my invention consists in the combined casting of the edge-plate A with the end flanges B B, pins z, and bottom plate so as to contract the parts, I use a simple flat or steel wire spring, K, so set down between the oblique flanges G and bent as to have its upper end directly bearing, against the back part of the bolt E, which has a groove on its under side, that fits over the, guide-ledge N, to hold it direct in its movement back and forth. I

This is an arrangement that results in a much narrower case, so simple as to be much cheaper than, and equally as good and durable as, those now in use, while it supplies an article much wanted in panel carriage-doors having narrow frames.

The catch-plate H is also improved by be-.

ing boxed out centrally at h, so as to form an inclined plane, J, for the beveled end of the bolt, which inclined plane is terminated by an open oblong slot, I, into which the bolt is shot by the spring 0, and sustains the front of the door. Thus it relieves the strain on the hinges, so injurious when the ordinary inclined catch is used, without any support to the vertical action or play of the bolt.

The tumbler F may have a square opening for any kind of a handle, L, or knob, to turn the bolt in order to open the door; or it may be adapted for a key, M, if desirable.

This combination can be applied to a right or left hand door.

I am not aware that there is an article of the kind to be had that supplies the carriagemakers wants as does this compact, narrow, and cheap combination, arranged as shown and specified.

I claim it as a new article of manufacture, resulting from the specific arrangement in the design of its parts, taken as a whole. In other words,

I claim- The combination of the faceplate A, and back and side plates, when cast in a single piece, and furnished with guide ledges N, oblique flanges G G, single bent spring K, working at one end against the depending portion of latch E, the whole; arranged and operating substantially as and for the purpose specified.

JosIAs 1). GOOD.
