Dec. 16, 1930. A. w. KIMBELL SPRING CATCH AND LIKE DEVICE Filed Nov. 30. 1928 fiwenton' Art/ear WKL'mbeZZ Patented Dec. 16, 1930 UNITED STAT rarer orr cs ARTHUR W. KIMBELL, or CHICAGO, ILLINOIS, AssrGNoR To onion MANUFACTURIN CORPORATION, OF CHICAGO, ILLINOIS, A. CORPORATION OFIIQLINOIS SPRING CATCH AND LIKE nnvIoE Application filed November 30, 19 28. -Seria1 No. 322,844.

My invention is directed to improvements in catch and like devices having an axially movable strike or catch member presented at one face thereof.

In the drawings accompany and forming a part of this specification, Figure 1 is a vertical section through one form of the device embodying my invention as it appears when it is in position for attachment to a relatively thin supporting structure; Fig. 2 is a section of the same elements shown in Figure 1, but with the annular wall of the casing part expanded; Fig. 3 is a side elevation of the device shown in Figure 1 and Fig. 4: shows views of each end of the device shown in Fig. 3.

The device which I have illustrated is adapted for use as a catch member such as is used in securing the doors of a cabinet or the like. However, a similar device may be used as an anti-rattle device. In fact, my invention is directed to devices having axially movable bolt, catch or bumper members normally urged forward by a spring. My invention is particularly .adapted for devices of the type mentioned having casing parts which must be flush or substantially flush with a supporting structure.

As best shown in Figs. 1, 3 and 4, the de* vice, which I have selected to illustrate my invention, comprises a casing part 2, an axially movable member 3 and means for attachment of the device to the structure 1. The casing part is formed from two separate pieces, one of which is in form of a cup and the other of which provides a front face portion l secured to the open end of the cup. This front face portion 4; has its edge rolled over the outwardly flared portion 5 of the cup and provides a flange 6 at one end of the casing part 2, as shown in Figs. 1 and 3. The bottom wall of the cup is upset or pressed inwardly to form a hump 7 which extends toward the mouth of the cup. The wall of the cup is divided longitudinally by a number of slits 8 terminating somewhat short of the flared portion 5. The other ends of the slits extend into the hump 7 but terminate somewhat short of the central point.

The front face portion l is provided with anaperture 5 through which a rounded end portion 9 of the axially movable; member 8 extends, as shown inFig. 1..v This member 3 has aflange 10 which. is normally pressed against the inner face of the front face porr tion bya coil springll contained: within the casing.

In applying the deviceto a relatively thin support 1 (Figs. 1 and 2) the cup ofthe casing part is thrust into a hole formed. in the support until the flange 6 seats against the front face of the support, as shown in Fig. 1.

Then a suitable tool is pressed against the rounded end 9 of the element 3 with sufficient force to pressthe element 3 against the end of the hump 7 and press it out, as shownin Fig. 2 (the element 3 being shown in dotted line position). Thus the annular wall of the cup is expanded laterally into the position shown in Fig. 2and the device is thereby held against accidental removal.

The sl'ts 8 aid' materially in the annular wall to be expanded laterally to a large degree.

I do not wish to be limited to the exact permitting I details of construction which I have shown and described because I am aware that the same general means of attachment may be had by slight changes of construction. Furthermore, my device may be attached to wood or like materials which will yield to permit the desired attachment when the cup is entered into a recess in such a support, 1

the casing may be attached to a supporting structure by flattening the boss to expand a portion of the said peripheral wall of the attaching portion.

2. A device of the class described comprising a casing part having a front face portion provided with an aperture, an axialopen end of the cup shaped part and having 1y movable spring pressed member projecting through said aperture and beyond the front face portion, and a cup shaped attach ing portion having a hump formed in the bottom of said attaching portion whereby the casing may be attached to a supporting structure by flatteningthe boss to expand a portion of the peripheral Wall of the casing part and said Wall and hump being split to permit ease of expansion of the said all.

3. A device of the class described comprising a casing having a laterally expansible cup shaped part, a cap secured to the an aperture therethrough, an axially movable spring pressed element having a rounded portion projecting through said aperture, and hump formed in the bottom of said cup shaped portion and extending toward said axially movable element and adapted to be pressed out by said axially movable element to expand the annular'wall of the cup shaped part when attaching the device to a support. 7

4. A device of the class described com- I prising a casing part having a frontface portion provided 'Wlbll an aperture, an axially movable spring pressed-member projecting through said aperture and beyond the front face portion, and easing expanding means provided as a part of the device whereby the peripheral Wall of the casing may be expanded laterally to secure the dename to this vice to a support. t

In testimony whereof, I have signed my specification. v ARTHUR W. 'KIMBELL.
