CATCH FOR DOORS AND THE LIKE.

Application filed March 7, 1922.

To all whom it may concern:

Be it known that I, WILLIAM a citizen of the United States, residing at the city of Bridgeport. in the county of Fairfield and'State of Connecticut, have invented certain new and useful Improvements in Catches for Doors and the like; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in catches, and while it pertains more particularly to catches used for G. WILSON,

doors or the like, still the invention is susceptible of other uses.

The primary object of the invention is to provide a catch of extremely simple construction, and one in which there are no parts likely to become deranged or otherwise cause inoperativeness.

A still further object of the invention is to provide a catch which is devoid of moving parts, except as to the latch, which latter may or may not be employed, and to further provide a catch which is of simple construction and which can be economically produced.

A still further object of the invention is to provide a latch which cooperates with the male and female members so as to efleotively prevent movement of the male member out of the female or keeper member.

The invention has still further and other objects, which will be later set forth and manifested in the course of the following description.

In the drawings:

Figure 1, is a top plan view, parts being broken away and in section showing the invention applied to a door and its frame;

Figure 2, is an enlarged sect-ion on line 2-2 of Figure 1, and

Figure 3, is a View similar to Figure 2, of a modified form of the invention.

In proceeding in accordance with the present invention, a male member is employed having a plate-like base 1 which latter is affixed in position by suitable fastenings such as screws 2. The base is provided with an integral shank 3 having a head 4:, the shank being shown inclined with relation to the plane of the base 1 and extending toward the frame F of the door D. The shank 3 Serial No. 541,720.

is possessed of considerable resiliency, being formed of material having sufficient spring or resilient property for the purpose, and preferably is of circular cross section depicted in Figure 2. The head 4: of the shank is generally of ball-like conformation, and has its dome preferably of wedge shape, so as to more readily find its way through the aperture 5 of the This member 6 is of plate for-inland has a suitable supporting or attaching base 7, the latter being secured by suitable fastenings, such as screws 8 to the door frame F. The aperture 5 of the keeper 6 is of preferably circular form and its circumferential wall rounded as illustrated in Figure 1, to thus cooperate with the head 4: in the entry of the latter through the keeper.

In operation, as the door is closed, the side a of the head l will strike against the wall 5 which defines the aperture 5, and will cause the shank 3 to spring in an outward direction until the head has completely passed through the opening, whereupon, due to the resilient nature of the shank 3, the base of the head will snap into engagement with the inner side face of the keeper 6 and hold the door in latched position. In opening the door, the base of the head t will ride over the keeper wall 5 and out of the latter.

9 is a latch pivoted at 10 to the keeper 6 and being of are or curved form so as to engage about the shank 3 and beneath the portion 4: of the head 4, so as to prevent movement of the head 4 out ofthe keeper aperture.

In Figure 3 of the drawings a modified form of the invention is disclosed and in which the shank and head of the male member 11 are formed of flat stock, the aperture 12 of the keeper being of rectangular shape as distinguished from the circular shape of Figures 1 and 2. In this form of the invention a substantially l -shaped latch 13 is employed which is pivoted to the keeper at 14. This form of the invention operates precisely as in the instance of the preferred form, the only differencebeing that the shank and head are formed of flat stock, the head having the same shape as that shown in Figure 1.

It is particularly to be noted that the entire inventionconsists of but two parts, excepting the latch, which may or may not be used, the sole spring feature being that keeper or female member 6.

of the shank 3. The parts may be drop "forged and with the exception of the pivoted latch, there are no movable parts whatsoever, the invention expressly avoiding the use of separate spring elements.

While the invention as illustrated includes an inclined shank 3, this shank may, of course, be straight and extend at right angles from the base 1, and the invention is not limited in this respect.

What is claimed is:

1. A catch including a male element having an attaching base, a resilient shank carried by the base, a wedge-shaped ball-like head on the shank, a keeper having an aperture to receive the headand having the wall defining the aperture rounded, the shank being relatively thick and stout so as to cause one side of the base oi the head to snap over and. into engagement with the keeper and the opposite side of the base of the head being spaced from the keeper, and a latch interposed between the keeper and head and pivoted to the keeper and movable into said space so as to engage the base of the head to prevent the latter from moving out of the keeper.

2'. it catch composed of a male member having a resilient shank and a rigid head, a keeper having a part apertured to receive the head, said part oi the keeper being rigid and engageable with the head to allow the latter to resiliently snap over the rigid wall defining the aperture of the keeper, anda latch interposed between the keeper and head and movable to lie between the head and keeper to prevent movement of the head out of the keeper.

3. A catch composed of a male member having a resilient shank and a head, a keeper apertured to receive the head, and a latch interposed between the head and keeper and pivoted to the latter to swing into and out o'l engagement with the shank and by engagement with the head to prevent move-' ment of the head out ot' the keeper.

In testimony whereoi I aflix my signature hereto.

-WllLLIAlil G. WILSON.
