Patented Oct. 22, 1929 UNITED STATES PATENT OFF IVAR C. LARSON, OF PROVIDENCE, RHODE ISLAND noon crime 7 Application filed May 20,

This invention relates to an improved construction of spring door catch or holder; and

has for its object to provide in such a catch 2 or holder a male member having a fastening 5 base and an enlarged engaging stud portion also having a gripping member with a base portion and a separate spring tongue secured to the base for gripping the enlargement of the stud member.

A further object of the invention is the folding of the end of the male or stud memher to provide a yielding engaging stud portion to cooperate with the spring tongue of the gripping member to releasably secure the two members together.

A further object of the invention is the v forming of the spring tongue of the gripping member separate and independent of its base portion whereby the spring tongue may be hardened independently of the base portion and so retain its gripping effect throughout a long period of use.

The invention further consists in the forming of a flange on the base portion of the gripping member against which one end of the tongue may rest, whereby it is only necessary to provlde a single rivet cooperating w t the flange for retaining the spring tongue in proper operatlve aligned positlon and pre- J vent it from swivelling.

With these and other objects invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings:

Figure 1 is a perspective view showing the stud member as being and the gripping member as 40 under side of a closet shelf.

in view, the? tongue riveted to its base. Also to provide an upturned lip or flange on the edge of the base member against which the riveted end of the spring tongue may abut to hold the tongue in 85 proper alignment and secure the same in that fastened to the door' fastened to the single rivet and hold the i927. sen-a1 No. 192,895.

Figure 5 is a perspective view of the stud member before itis folded.

Figure 6'shows the stud member formed from'a strip of sheet stock and having rightangularly disposed portions, one of the por- 155 tions having its end portion folded back upon 'itself to form a resilient enlargement.

resilient to cooperatewith the spring of the gripping member which resiliency is obtained by folding the operating end of the stud member back upon itself with the part-s slightly spaced from each other so as to permit ayielding action under the pressure tens'ion of the spring tongue also to provide a gripping'member which is provided with a base formed of ordinary untempered sheet/ stock and to. provide a separate tempered position by the use of but a single rivet; and the following is adetailed description of the present embodiment of my invention and showing one means by which these advantageous' results maybe accomplished?- VVith referenceto the drawings, 10 designates the strip of metal from which the stud member may be formed,v the same being first punched with holes 11 therein to receive the fastenings screws'12.-' i

This strip is then folded preferably adja cent its middle section and the stud end 12 is then folded' back" upon itself as at 13, see

' Figure 6," the parts being spaced from each door to which it is attached;

The gripping member comprises essentially,

a base plate 15 having laterally-extending cars 16 pierced as at 17 to receive the fasten. ing screws 18 and the rear edge ofthis base plate -is turnedup as at: 19 providing an abutting flange against which the end of the spring tongue. 20 rests. This spring tongue is formed-eta hardened strip of steelpunched at121 and squared at. its-secured end. at 22 to abut against. this upturned flan e and is punched-asat. 21 to provide a 110 e for. the rivet. 22- and is. secured in position by. simply passing thesr-ivet therethrough andheading it on the under side of the plate.

By this construction it willbe seenthat the base-platemay be made of ordinar soft metal easily stamped out andpunche whilethe spring tongue may bermade of tempered steel which will maintain, its grippingefficiency throughout the ,life of. the. device.

In some instances instead of usingaspring tongue: of single thickness I. may superimpose-one or. more tempered spring leaves 23 .uponthe base-leaf 20 and secure the same in position-by theuse of but. a-single rivet 24, as

- illustrated in Figure 9.. In this way the gripping: action. of. the spring. may be. made as strong; asis desired.

My improved stud member. 25 may, be secured to a. closet door 26. or other support while'the gripping member 27may besecured to the under side of a closet shelf or other support sothat when the-door. is swung closed the'gripping member will releasably engage the. stud member and soxreleasably retain the door in. closed osition until it is desired to openthesame a simpleopening pull. and by forming the spring tongueof a tempered material the same will retain its gripping effect throughout the working life of the de- V106.

The, foregoing description .is directed so1e-. ly towards the-construcation-illustrated, but. I I vdesire itto; be understoodthat I. reserve the privilege. of resorting to all the. mechanical changes to which the device. is susceptible, the invention being; defined. and limited only, by the terms of the appended: claim.

I claim:

A spring door catch or holder com rising a. stud member formed of; a strip 0 sheet stockhaving asupporting element anda right v angularly. disposed, enlargement formed thereon. with atapering entering edge,.and a IVAR C. LARSON.
