LATCH.

Specification of Letters Patent.

Patented Mar. 14, 1916.

To all whom it may concern 1 Be it known that I, MINER S. KEELER, a citizen of the United States, residing at Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Latches, of which the following is a specification.

This invention relates to improvements in latches.

My improvements are especially designed by me for embodiment in latches for doors, such as the doors of kitchen cabinets, cupboards and the like, although they may be readily adapted and are desirable for use in latches for heavier doors, such as refrigaccompanying drawings as I have embodied them for use on light doors, such as kitchen cabinets, cupboards and the like.

The main objects of my invention are: first, to provide an improved latch in which the parts may be formed of sheet metal stampings and are simple and economical to produce and easily assembled; second, to provide an improved latch which is effective and at the same time compact and attractive in appearance.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a front elevation of a structure embodying the features of my invention with the latch mounted upon a door and a coacting keeper mounted upon the door casing, the latch being shown in its keeper engaging position. Fig. II is a detail section on .a line corresponding to line 22 of Fig. I, the catch being shown in its disengaged position by dotted lines. Fig. III is a detail vertical section through the latch on a line corresponding to line 3-3 of Fig. I. Fig. IV is a plan View of the blank from which the latch housing or casing is formed. Fig. V is a plan view of the blank from which the keeper is formed. Fig. VI is a plan view of the blank from which the catch and its lever are formed. Fig. VII is a perspective View of the catch and its lever removed from the housing. In the drawings similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawings, 1 represents a door and 2 a door casing on which the parts are shown. The latch housing or casing is formed integrally of sheet metal and comprises a top wall 3, side walls 4 and end walls 5, the side and end walls being turned rearwardly from the top wall. The blank from which the housing is formed is shown in Fig. IV. The end walls 5 terminate in laterally turned lugs 6 perforated at 7 to receive the attaching screws 8. The top 'wall is provided with an opening 9, while one side wall hasan opening 10 therein. The catch and its lever is also an integral sheet metal stamping. The catch lever 11 -.is provided with rearwardly turned side members 12 and 13 at its inner end adapted to be disposed in the opening 9 of the housing and constituting pivot ears or members. These side members have holes 14: therein for the. pivot 15 which is arranged through the side walls of the housing and through these lever side members. The lever side member 13 terminates in a laterally turned extension 16 constituting the catch or keeper engaging member. This catch projects through the opening 10 in the side wall, the ends of the opening being preferably adapted to serve as stops for limiting the swing of the lever. At the inner end of the lever 11 is a rearwardly turned arm 17 disposed between the lever side members 12 and 13.

A coiled spring 18 is arranged in the housing with one end supported by one end wall and the other engaging this arm 17 to hold the lever with its catch yieldingly in its keeper engaging position. The end wall and the arm are provided with spring re taining lugs 19 formed by punching or striking up portions thereof. (See Fig. III). These lugs effectively hold the spring in place.

The keeper 20 is provided with an attaching plate or base '21 perforated at 22 to receive the attaching screws 23. This is also preferably a sheet metal stamping.

The keeper has oppositely inclined edge 24 with which the catch engages, the keeper being positioned so that the catch will strike the outwardly facing inclined edge'of the keeper and slide over it into engagement. with the inwardly inclined edge thereof. The spring pressing on the lever serves to press the door toward the jamb or casing. The stops for the lever are preferably disposed so that the lever normally lies close to and substantially parallel with thetop of the housing. I

By supporting the catch lever by pivots arranged through the side members the transverse or twisting strains thereon are effectively withstood although the parts may be of comparatively small size and of light material. V

I have illustrated and described my improvements in detail in a simple and prac tical embodiment as I have placed the same on the market. I have not attempted to illustrate or describe various embodiments or modifications which I contemplate to adapt the latch to special or particular purposes, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embodyor adapt the same as conditions may require or taste dictate. I desire, however, to be understood as claiming my improvements specifically in the-form illustrated as well as broadly within the scope of the appended claims.

Having thus described my invention, what 1 I claim as new and desire to secure by Letters Patent, is:
