BASIL R. CRAMPTON, OF CHICAGO, ILLINOIS.

LATCH FOR DOORS AND OTHER PLACES.

Specification of Letters Patent Patented Apr. 4, 1911.

Application filed July 29, 1910. Serial No. 574,474.

To all whom it may concern:

Be it known that I, BASIL R. CRAMP'roN,- a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Lateh'for Doors and other Places, of which the following is a specification.

My invent on relates to improvements in latches in which a keeper and a pin or bolt .are alternately engaged and disengaged as the door or doors on which they are placed are closed or opened. And this invention is an improvement of the, device set out, de-

- scribed and claimed in Letters Patent of the United States issued to me July 13, 1909, No. 928,030; and the object of the invention is to obtain a device which can be made cheaplv, which is durable, not liable to get order, is easily operated, readily mounted in place on doors. or other objects,

and which will continuously hold the doors or other articles on which the device is mounted tightly closed.

' The latch comprises two members, one of which has a holding member, adapted to be placed in a holding and in a releasing position, which member corresponds with the member called the keeper in the patent res, ferred to, and which is herein called a keeper; and the other of which consists of a pin or bolt which is adapted to be held by the keeper when said keeper is in a holding position, and to be released from said keeper when it is in what I have termed above a releasing position.

The member termed the bolt or pin in.- cludes a handle, which may be integral with said bolt or pin, or movable thereon.

In the accompanying drawings;-Figure 1 is an elevation of the movable members of the keeper of the device; Fig. 2 is a side elevation of the device with the several parts illustrated in full lines'in the engaging position, and with the keeper indicated by broken lines in the releasing position; Fig. 3 is a front view of the device, with the several parts in the engaging position; Fig. 4 is a rear side elevation of a movable handle which forms a part of the pinor bolt member: Fig. 5 is a sideelevation of the device,

with the several members in an engaging position, and attached to the doors of a re- 1 frigerator, showing a small'portion of said doors; Fig. 6 is a' front view of the device, with the several members in an engaging posit1on-,,an"d attached to the doors of. a refrigerator, showing a small' portion of said doors; Fig. 7 1s a side elevation of a button forming an element of the device; Fig. 8 is a front elevation of the button illustrated in Fig. 7; Fig. 9 is a perspective of a collar which forms an element of the device which is illustrated in Figs. 2, 3, 5 and 6; Fig. 10 is a front elevation of a pin or bolt member having a handle rigidly attached thereto by being made integral therewith; and Fig. 11 is a side elevation of the pin or bolt member which is shown in front elevation in Fig. 10.

Similar letters refer to similar parts throughout the several views.

. The levers A, B, provided with projecting ends a, b,recessed ends C, C, button D and springE constitute the keeper member of the device. Lever A is provided with finger a. Spring E is attached to the door or other thing on which the keeper member of the device is to be mounted, by the screws F. F,

and forms the base, as well as the yielding member, of thekeeper. I

G, G, are recesses in recessed ends C, C, of levers A and .B, respectively. When the keeper is in an engaging posit-ion the parts 0 of the recessed ends C, C are near to contact; and when said keeper is in a releasing position the parts 0 of said ends are in contact, or nearly so. The projecting ends a, 1), limit the outward movement and posi tion of the levers A. B. when the keeper is in a releasing position, by said ends coming into contact with the spring E, as is indi cated by the broken lines in Fig. 2.

When the several parts of the keeper memher are assembled. the shank d of button D is in the recesses G. and is maintained in place by the flanges (l. (l. and theaction of the spring E. and the levers A, B. are attached to the spring by the'pins H, H,- which extend through the holes or apertures It, 72-, (see Fig. 1) in said levers. The spring E is turned around the pins H, H, at its ends 6, a, (see Figs. 3 and 6).

f. are apertures in spring E. through which the screws F extend when said spring is attached to a door or other object.

I is a pin or bolt. mounted on base J. Base J is provided with apertures or holes 7'. through which the screws F extend when said base 'is attached to a door or other object.

J is a projection on base .T. (Figs. 2 and 3).

K is a door on which the keeper of the descrews F.

. with spring E when said lever is used to break the'engagement of pin or bolt I with the keeper member.

FM is a'coll'ar which fits loosely over the pinor bolt I. Collar M is held in place on the pin or bolt I by slightly enlarging the end of said pin orboltwith a hammer, or

by pressure. Collar M holds the lever L inplace, and said collar comes in contact with the levers A, B, when doors K K are closed and the'keeper engages the bolt. Then the I keeper is brought into a releasing 'position the collar M passes out from engagement with the finger a and when the keeper is in an engaging position said finger a is over and 1n contact with sald' collar. To provide for the contact of the finger a with the collar when the keeper is in the engaging position, the base J is'made of a height, relative to the position of the keeper levers A, vB, so

- that when the doors on which the device is placed'are closed, the bolt or pin I will permit the levers A, B, to be forced into substantially the position illustrated in Fig. 5, with the button ,D not in'contact with the spring E, but near to contact therewith, as

is illustrated at X. As said spring E tends to move the levers A, B, into the position illustrated in Fig. 2, with the button D in contact with spring E, as is illustrated at X in said Fig. 2, there is a constant pressure of finger a on collar -M, when the device is mounted on doors and said doors closed, and thereby said doors are maintained tightly closed by the device. Of course the device may be mounted with the keeper on the casing bfla door, and the pin or bolt mounted on the door, if there is but one door to the refrige rator-,in which case K represents the casing of a door and K the doer; I The pro ection J, (Fig. 4= ),'"is to prevent the-lever L getting into. position to prevent the shutting oi the door on :which the base J and pin or bolt I are mounted. All that is required to effect this result is to place the projection J in the path of movement of the lever L, so that said lever cannotturn on pin or bolt I so as to present the end thereof to spring E asthe door is closed.

(In Figs. 10 and 11 the handle L is intogral with base J and bolt I, and may be grasped -to'open the door on which said pin or bolt is mounted, (by means of base J).

The end Z of'lever L is made of such length from the pivotal point of said lever, that said end will pass by the turned end 6 of the spring when levers A, B are in subsaid end will hit the door or other object on which thefbase J is attached at or just before. the time when the pin or bolt I has forced the levers A, B, into the same plane, or substantially so, and so move the end Z by the end 6 forces the levels A, B through and beyond the same horizontal plane the end Z assumes substantially the position illustrated in Fig.

.of spring E, which is adjacent to said end Z. Bythis construction, as thepi'n or bolt I 5, and to open the door easily the end Z of 89 lever L'is grasped and said lever is turned on its pivot, whereupon the end Z forces said door open.
