Patented Feb. 27, 1934 UNITED STATES PATE= oF c 1,948,908 DOOR PULL AND LATCH Carol L. Evans, Tipton, Calif. Application August 15, 1932. Serial No. 628,924

5 Claims. (01. 292-202) I My invention relates to improvements in door pulls and latches, and it consists of the combinations, constructions and arrangements hereinafter described and claimed.

6 An object of my invention is to provide a door pull and latch designed primarily to be used in cupboard doors. The handle is pivoted to a trigger which in turn carries the latch or hook and the weight of the handle aids in holding the hook 10 in engagement with a catch. The hook is in the shape of a cone and this permits the hook to be rotated and still engage with the catch. The hook has a threaded stem received in the trigger and a rotation of the hook will adjust it with respect to the trigger and to the catch.

A further object of my invention is to provide a device of the type described which is simple in construction and in which a horizontal outward movement of the weighted handle will first free the hook from the catch, and then will swing the cupboard door into open position. The handle need not be engaged during the closing movement because the cone-shaped hook will automatically engage with the catch and the weighted handle will hold the hook in engagement.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.

0 My invention is illustrated in the accompanying drawing forming a part of this application, in which Figure 1 is a vertical section through the device, portions being shown in elevation;

Figure 2 is a section along the line 2-2 of Figure 1;

Figures 3 and 4 are front and rear views of a part of the device; and

Figure 5 is a front elevation of another part 0 of the device.

In carrying out my invention I make use of a cupboard shelf 1 and a cupboard door 2. A catch 3, L-shaped in cross section, is secured to the shelf 1 by any suitable fastening means such as screws 4.

The door 2 has a bore 5 for receiving a cylindrical portion 6 of a casing 7. The casing 7 has a trigger plate 8 and the plate has projections 9 designed to be imbedded in the front of the door. The cylindrical portion 6 is snugly received in the bore or passage 5 and has a slot 10 extending therethrough. The plate 8 has an opening 11 registering with the slot.

A trigger 12 of the shape shown in Figures 1 and 2 is pivotally mounted in the slot 10 and opening 11, and is fulcrumed on a pin 13 that extends transversely through the slot and is carried by the portions 6, see Figure 4. The trigger 12 is provided with a notch 14 for receiving the pin 13. The trigger 12 also has a projection 15 that is square in cross section, and this projection has a threaded bore 16 for receiving the threaded shank 17 of the conical shaped latch or hook 18. The shank 17 is slightly larger in diameter than the bore 16 and the projection 15 has a slit 19 extending throughout its entire length. When the shank 17 is screwed into the bore 16 the slot 19 will permit a slight expansion of the member 15, and the member 15 will therefore frictionally engage with the shank and hold it in adjusted position.

A disc-shaped plate 20, see Figure 5, has a rectangular opening 21 for slidably receiving the shank 17 and has two openings 22 for receiving screws 23, see Figure 2. The plate 20 has a flange 24 that bears against the inner surface of the door and the plate is secured in place and to the cylinder 6 by the screws 23. Figures 2 and 4 show the cylinder 6 as being provided with threaded portions 25 for receiving the screws 23.

A weighted handle 26 is secured to the trigger 12 by a link 27. The handle 26 may be secured to the trigger in different ways. For example, the link 27 can be rigidly secured to the handle 26 and pivotally secured to the trigger, or a link may be pivotally secured to the handle 26, a second link pivotally secured to the trigger 12, and both the links connected to each other by a third link not shown.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

The conical shaped hook 18 is adjusted in the bore 16 so that it will engage with the catch 3 when the door is closed. The hook can be quick ly adjusted and will engage the catch in all positions because the hook is in the shape of a cone. In opening the door the person grasps the handle 26 and pulls outward. This movement will swing the trigger 12 in a clock-wise 100 direction about the pin 13. The shank 17 will be moved downwardly in the slot 21 and the latch or hook will be freed from the catch 3. Further outward movement on the handle 26 will open the door.

The door can be closed by merely swinging into closed position. The force of the moving door will be suiiicient to cause the hook 18 to move beneath the catch 3 whereupon the Weighted handle 26 will swing the trigger 12 in a counter- 1m.

clock-wise direction in Figure l, and will cause the hook to engage the catch.

While I have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

I claim:

1. In a door pull and latch, a casing having a trigger guide, atrigger fulcrumed in the guide and having a slit post with a threaded bore, and a latch having a conical-shaped head and a threaded shank adjustably received in the bore.

2. In a door pull and latch, a casing having a plate for engaging with the outer surface of the door, said casing also having a projection insertable into the door, a plate bearing against the inner surface of the door, fastening members securing the plate and casing together, said cas ing and plate having guides, a trigger received in the casing guide and latch received in the plate guide and being secured to the trigger with freedom of removability while the parts are in assembled position.

3. A door pull and latch comprising a catch having a downwardly extending stop, a trigger swingable in a vertical plane, a latch threadedly and extensibly engaging the trigger and having a cone-shaped head engageable with the stop, and a weighted handle pivoted to the trigger.

4. A door pull and latch comprising an L- shaped trigger swingable in a vertical plane, a handle pivoted to the trigger below the pivot point of the trigger, a latch threaded into the trigger and having a conical-shaped head, and a catch having a downwardly extending stop placed in the path of the latch.

5. A door lock comprising a casing adapted for introduction into a door opening and having a slot therein, a pin extending transversely through the slot, a trigger having a notch adapted to take bearing on the pin when inserted in the casing and a latch secured to the trigger, the latch being removable to facilitate insertion and withdrawal of the trigger.
