ATTORNEY.
u xgl Patented Mar. 23, 1943 UNITED STATES PATENT OFFICE Original application October 17, 1936, Serial No.
106,243, now Patent No. 2,224,512, dated Decem- Divided and this application September 11, 1940, Serial No. 356,275 7 Claims. 01. 292-213) This application is a division of my Patent No. 2,224,512, issued December 10, 1940, for Door latch.
'This invention relates to a Wedge type keeper for rotary latches, whereby the closure on which the latch is mounted is held in a number of directions, namely in a closing direction; an opening direction, and in a direction substantially in the plane of the closure and the frame in which it is mounted.
An object of my invention is to provide a novel keeper which is adapted to be clamped between a rotary bolt and a stationary guiding surface, this guiding surface and the keeper having coacting, inclined surfaces which tend to pull the closure towards the frame;
A feature of my invention resides in the novel wedging keeper of the character stated, which holds the door against both horizontal and vertical movement.
Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.
In the. drawing:
Figure l is a fragmentary, sectional view taken on line il of Figure 2.
Figure 2 is a fragmentary, sectional View taken on line 22 of Figure 1.
Referring more particularly to the drawing, my wedge keeper for rotary latches includes a latch frame I, which is suitably attached to or mounted in a door or similar closure. A rotary bolt 2 is rotatably mounted in the frame I on a horizontal pin 3. The rotary bolt 2 may consist of a plurality of latching heads 4, any one of which may engage the keeper 5. One or more cam dogs 5 engage the various heads or surfaces of the rotary bolt 2 for the purpose of camming the heads 4 of the bolt against the keeper 5, as will be subsequently described. The cam dogs 6 may be of the type shown in my copending application, Serial No. 106,243, which has matured into the patent above mentioned.
A stationary lug l is mounted opposite to the rotary bolt 2 and spaced therefrom substantially as shown. The keeper 5 cooperates with the stationary lug l for the purpose of holding the door securely in position and against horizontal movement, as will be further described. The upper surface 8 of the lug l is inclined inwardly substantially as shownthat is, the surface 8 is arranged at an acute angle to a horizontal plane.
The lower surface 9 of the keeper 5 engages the surface 8, substantially as shown in Figure 2- that is, these surfaces engage and co-act when the closure is in latched position. I thus provide a wedge or dovetail connection between the lug I and the keeper 5 which holds the door against spreading away from its frame.
The keeper 5 is provided with an inclined surface l0 against which the heads 4 of the rotary bolt bear when the closure is in latched position. The rotary bolt thus presses the keeper inwardly to hold the door against swinging movement, and also presses the keeper against the stationary lug l and holds the inclined or wedged surfaces 8 and 9 in close engagement. When the closure is completely closed, the keeper 5 bears againstthe stop II and is pressed against this .stop by the rotary bolt 2.
