3 Claims.

This invention relates to door latches and particularly to a door latch embodying a member with a recessed portion having a transverse abutment and a cooperating member provided with a projecting portion which abutment and portion are adapted for resilient engagement with each other for holding the door in its closed position. One of the principal objects of the invention is to provide a latch of this type which will not become clogged by paint or varnish in its working parts and another object is to provide an article in which the outer finish of the exposed part is not produced by painting, varnishing or the usual forms of enamel. Still another object is to pro-- vide a device of this type having improved and novel means for assembling or applying the parts and alining the same. And a further object is the production of an improved latch of the above type which is more simple and of lower cost of 0 manufacture than those now lnuown to us.

With the foregoing and other advantageous features in View which will appear as the description progresses, we have illustrated our improvements in the drawings accompanying and forming part of this specification, and in which- Figure 1 is a front elevation showing one form of our invention applied to a door.

Fig. 11 is a front elevation of the stationary portion of this form.

Fig. 12 is a front elevation of another form of our improvements.

Fig. 13 is a vertical section of a part of the same taken on the line 13-13 of Fig. 12.

Fig. 14 is a vertical section of the same taken on the line 14-14 of Fig. 12.

Like characters of reference refer to like parts in the several figures of the drawings.

Referring first to Figs. 1 to 6 of the drawings, the numeral 2 indicates a member which is secured to the movable portion such as the door D which is to be latched. This form of the member is formed with a raised middle portion 3, side 0 portions 4 through which suitable screws 5 are passed to secure it to the door D, and beveled portions 6 along the edges of the side portions.

If desired a knob 7 may be provided for opening and closing the door or other article to which 5 the device may be applied, said knob being held by a screw 8 passed through the knob and a suitable aperture in the member 2 into the door D. The raised middle portion 3 is grooved at 9 on the inner side of said member and has two oppositely disposed abutments 10 formed by the inner surfaces of the side walls of said groove 9. The said abutment-,5 are preferably provided with indented or beveled parts or notches 10 for the engagement of parts presently to be described.

The member 2 may be formed in any suitable manner but is preferably made of sheet metal in the form of a stamping l1 and a covering element 12 of suitable material such as glazed celluloid of any desired color is secured to the 80 stamping 11. This may be eifected in any suitable way as by turning under the edge portions 13 as shown in Figs. 3 and 4.

' There is a member 14 provided to be engaged by the member 2 to hold the door or other article fitted with it in its closed position as in the doorway of the doorway frame F and said member 14 is provided with a portion 15 transverse to the door front surface to engage the transverse abutment in the member 2. In the form 9 shown in the figures two such portions 15 are provided and each may be furnished with a rounded or curled part 16 so that the abutments 10 may readily pass on and off them and to engage in and hold by the notches 10 when these 9 are provided. There is also a base portion 18 joining said portions 15 said portion being provided with a perforation 19 through which is passed the screw 20 for securing the member 14 to the frame F of the doorway. There is an alining element 17 preferably placed at the upper end of the member 14 and formed by bending over a portion of the same transverse to the base portion 18. The door is fastened by the foregoing device by merely pushing it firmly to its place in the doorway and the curled parts 16 then immediately engage with the indented parts or notches 10' and hold the door in place and it is opened by firmly pulling it outward.

When it is desired to apply this form of latch to a door or other article, the member 14 is first placed in position on the frame of the doorway as shown in Figs. 5 and 6 with the portion 17 alined on the edge of the frame F. The screw 20 is then applied and the member secured in place. Next the door D is closed and the member 2 is placed on the front of it, placing the recess or groove 9 over the portions 15 and alining the raised middle part 3 to the edges of the door D. The screws 5 are then applied and the handle or knob '7 if there be one is secured in position.

In the form of our invention shown in Figs. '7 to 11 inclusive, the member 2 is in the form of a heart-shaped metal plate or stamping 21 and has a cover element 22 similar in form but preferably furnished with a raised part 23 having a recess 24 in its inner surface and immediately over a pair of perforations 25 in the plate 21. At the adjacent edges of the perforations are placed the abutments 9, which are here formed by the struck up flanges 26 on said plate 21.

There is a member 1a to be engaged by the abutments 10" and said member is similar to the member 14 of Figs. 2, 3, 5 and 6. Said member 14 has two transverse portions 15 and 2'7, the former provided with a rounded or curled part 16' and the latter being without such part. These two portions resiliently engage the abutment surfaces 10 on the outer sides of the struck-up flanges 26. The member 14' is secured on the doorway frame F or other suitable member and instead of the arrangement shown in Figs. 1 and 3, the inner portions of 15 and 27 engage the outer surfaces 10 and the curled part 17 engages the top of the right hand flange 26. A suitable screw 20' passed through the aperture 19 secures the member 14 to the frame F. The method of fastening and unfastening the door is similar to that for the first form of the invention.

In the form of our invention shown in Figs. 12, 13 and 14. there is a heart-shaped plate or stamping 30 held by the screws 31 on the door D2 and also a knob 32 held by a screw 33.

- Fastened to the plate 30 is an element 34 having portions 35 and 36 transverse to the door surface and preferably resilient and joined toeach other by the top portion 3'7. The portion 35 is preferably more resilient than the portion 34 and has a struck-in portion 38 preferably circular in form. There is a ring 39 preferably of round wire and provided with a screw threaded stem 40 by which it is fastened to the doorway frame F2. When the door D2 is closed the portions 35 and 36 resiliently clasp the ring 39 as seen in Fig. 14. On giving the knob 32 a strong pull the door is opened and it is shut by pushing it firmly to place in the doorway.

What we claim is:-

1. In combination, a member secured to a door having a portion overhanging the frame of the doorway and provided with a pair of oppositely disposed, relatively fixed, spaced abutments, and a device secured to said doorway frame and alined to said member, provided with two relatively movable elements each having a free end portion adapted to engage one of said abutments for holding the door closed.

2. In combination, in a door latch, a member secured to a door having a portion overhanging the frame of the doorway and provided with a pair of oppositely disposed, relatively fixed, spaced notches, and a device secured to said doorway frame which includes a flat portion by which it is secured to said frame and two outwardly extending elements one at each end of said flat portion and whose free end portions are movable relatively to each other and adapted to engage said notches for holding the door closed.

3. In combination, a door member embodying an outwardly covered recess having two opposed notches, and a door jamb device including a stamped metal member and a single holding screw therefor having a head, said stamped metal member provided with a flat base having a perforation for said screw, a rearwardly turned alining element and two forwardly turned resilient holding elements each of the latter having a free end to engage in one of said notches when the door is closed, said holding elements spaced apart a distance not less than the diameter of said screw said perforation being between said elements and said notches in working alinement with said holding elements, and said alining element being in alining engagement with the edge of the door jamb.
