DOOR-CATCH.

Specification of Letters Patent. Pat t Ma 7 ,191

Application filed 1111723,.1917. Seria1No'.182,998.

To all whom it may concern L Be it known that I, CHARLES J. DAVIDSON,

a citizen of the United States, residing at Grand Rapids, in the county of Kentand" State of Michigan, have invented certain" new and useful Improvements in Door- Catches, of which the following is a specification.

My invention relates to improvements in door fastenings for use upon commodes, buffets, etc, and its objects are: first, .to dispense with the use of pivot pins for adjustably securing the handle and catch to its supporting element; second, to provide a door fastening in which the handle and fastening are integral; third, to provide a door catch that may be made of the fewest possible number of pieces and be absolutely effective in its operations.

I attain these objects by the peculiar construction shown in the accompanying drawing, in which Figure 1 is a plan of the blank from which the latch support is made. Fig. 2 is an elevation of the latch support complete. Fig. 3 is an elevation of the latch securing element shown as mounted on a commode side. Fig. 4 is a plan of the blank from which the latch and handle is made.

Fig. 5 is a. bottom plan of the handle- Fig. 6 is a side elevation of the same. Fig. 7 is a plan of a piece of cupboard door with my fastening complete and in place. Fig. 8 is a side elevation of the same.

Similar reference characters indicate similar parts tlu-oughout the several views.

I make this fastening of thin sheet metal. The supporting element 1 is made from a blank of practically the form in Fig. 1, which is bent at right angles upon the dotted lines and so formed that the hole 0 will come directly back of the hole 6, for the free passage of the screw 2 through both holes, and the point (Z passed into the wood, all as indicated in Fig. 2, so that with but the one screw, 2, the support will be held very rigidly upon the stile of the door 10.

The latch and handle are made of a single piece of sheet metal practically of the form shown in Fig. 4. The handle proper is curved, practically as more plainly shown in Fig. 5, with the wings 5, 5 inclining, relatively backward and upward to form the latch proper shown at h in Figs. 7 and 8, .or at h in Fig. 6. From 72 the blank is forced relatively outward forming the arms 6, 6 terminating in the plate 4 which is provided with a slot f for the free passage of the screw 2. At the relatively lower edge of theplate 4, andcontinuing from the arms 6, 61 form two lugs, e, e that are designed to rest in the notches a, a in the support to form the substitute for a pivotal bearing in the support for the handle andlatch. After the handle and latch have been formed the plate 4 is placed inside of the support 1 with the lugs e, e resting in the notches a, a, as hereinbefore intimated, ,and the spring 8 is placed between the plate 4 and bottom or base plate of the support, and the screw 2 is passed through the hole I), the slot 7, the spring 8 and the hole a and screwed into the door stile 11, practically as shown in Figs. 7 and 8.

The catch for use with this latch consists of a thin piece of sheet metal cut and formed practically as indicated in Figs. 3, 7 and 8. This catch is bent to practically the form shown at i, j, and 7. The part jforms the base and rests upon the edge of the door casing, where it is firmly secured by means of the point Z and the screw g, properly screwed into the wood, as shown in Fig. 2. The wing i is made short enough to form an opening is between it and the surface of the wood for the free passage ofthe latch 71., as shown in Fig. 8, where the latch is held, normally, by the spring 8, assisted, of course, by the influence of gravity upon the handle 3. In Fig. 6 I have shownthe latch, h, bent double. This is to form a round edge to come in contact with the wing 11 on the catch to avert the danger of unduly marring the wing, if desired.

It will be readily seen that with this construction the handle and latch may be used either as a right handed, or as a left handed fastening for doors without any change whatever in any part of the appliance.

What I claim as new, and desire to secure by Letters Patent of the United States, 1s:

1. In a door fastening, a supporting element made of a single piece of sheet metal bent to form a hollow cube and having screw holes set in direct alinement, and having notches at the corners of one edge, a handle,

a latch and an actuating body made of a single piece of sheet metal, the body having a slot for the passage of the supporting screw lugs formed on the handle to engage the notches in the support to form pivotal bearings for the handle, a spring in the sup- 2. In a door fastening, a supporting'element made of a single piece of sheet metal f'bent to form a hollow cube having two screw holes in direct alinernent,also having notches at the two corners of one of the edges of lo the cube, two latches, a handle and a plate Inade of a single. piece of sheet metal, lugs on the handle to engage the notches in the supporting element, the plate having a slot through it, aspring acting upon the plate,

and a point on one Wing of the supporting element, all arranged to be firmly secured to a door stile With a single screw, and a catch arranged to engage the latch to hold a door securely closed.

Signed at Grand Rapids, Michigan, July 21, 1917. t CHARLES J. DAVIDSON.
