1 claim. (cl. asa- 76) w This invention relates to new and useful improvements in door catches generally, although more` particularly to `those `embodying a spring drawing. c

Referring to the drawing in detail, my inventionis embodied in a door catch A for a door casing installation with single doors, a door catch B for door casing installation for double doors,

a door catch C for door jamb installation for single doors, anda door catch D for door jamb installation for double doors.

The door catch A, as shown in Figs. 1, 4, 6, 7 `The principal object of my invention is to proand 8, is formed from a piece of resilient sheet t5 i vide a door catch having a spring tongue adapted metal which is bent transversely intermediate i `to be yieldably engaged `by a door to hold the its ends to form an upstanding attaching ange latter ,aieosed position, t 5 and laterally extending yieldable dooreenc Ano ero ject of my inven ion is to provide gaging ongue the Ilange and the `tongue being lo asingle device of the above: character which is 1disposed in substantially right angular relation "10 adapted for use with a pair of doors whereby o each other.

a door and casing showing the application of a In Figs. 1 and 4, I have shown a door casing I3 door catch constructed in accordance with my having a transverse bar I4, and a door I5 hingedinvention, 1y mounted in the casing. The door catch A Figure?1 is a Simlilar lit-131il etept thallgmy 1001' is mounted on the bar I4 with the attaching 25 Catch iss 0WD appied o e oor jam fiange 5 on the exterior surface of the bar I4 Figure 3is afragmentary front elevation showand the age lzldisposed against the under ing mitfhdoor catchdapplied t0 a dOOr lamb fOI surface of the bar.

i9. Each tongue Il is bent to the same configuration as the tongue 6 of the catch A.

In Fig, 3, l'. have shown the top bar 20 of a door casing and a pair of cooperating doors 2l, 2| mounted in the casing. The doorcatch B is mounted on the bar 2i! and is symmetrically Idisposed relative to the meeting edges of the The attaching flange I6 is` located on the exterior surface of the bar V20 and the tongues Il, il are disposed against the under surface of the barand respectively over the doors. Thus it will be seen that either door may be opened or closed independently of the other, and that in so doing the action of the top of each door upon its cooperating tongue Il is the same as the tongue of the catch A.

The door catch C, as shown in Figs. 2 and 5,

is similar to the door catch A, but the upstanding attaching flange of the catch C is of lesser height than that of the catch A, whereby the catch C is adapted to be installed on the door jamb of a single door. v

The door catch D, as shown in Figs. 10 vand 11, is similar to the door catch B but the upstanding attaching flange of the catch D is of lesser height `than that .of the catch B, whereby the catch D is adapted to be installed on the door jarnb of double doors.

In Figs. 12, 13, and 14, I have shown several modied catches E, F and G respectively.

In Fig. 12, I have shown a door catch E formed from a piece of sheet metal bent transversely intermediate its ends to form an upstanding'attaching flange 22 and a laterally extending tongue 23 which is bent transversely to a nat V- shape as seen in side elevation. In Fig, 13, I have shown a door catch F similar to the door catch E and including an attaching flange 24 and a tongue 25 similar to the tongue (i of the catch A but having its free end extending upwardly. In Fig. 14, I have shown a door catch F similar to the door. catch E and including an attaching flange 26 and a downwardly extending curved tongue 2l as seen inside elevation.

Thus it will be seen that I have formed a door catch which is operable with a single door whereby the door will be frictionally held in a closed position, or with double doors whereby both doors will be frictionally held independently in closed positions. k Y

It is of y'course to be understood that the details of structure and arrangement of parts may be variously changed and modified without departing from the spirit and scope of my invention.

I claim:

A door catch of resilient sheet metal bent intermediate its ends to form an upstanding attaching flange and a laterally extending yieldable door-engaging tongue, said tongue being bowed Vdownwardly to form a downwardly infclined front end portion, a centrally disposed nat door-engaging portion, and anupwardly inclined rear end portion, said front end portion joining said attaching ange to conjointly form a right angled structure, wherebythe attaching flange is .secured exteriorly of the door casing and with the said door-engaging tongue interposed between thle inner edge oi the door casing andthe said door ina manner whereby no parts `project beyond the outer plane of the said vdoor casing, and wherein the downwardly inclined i'ront end portieri and the upwardly inclined rear end portion of the .door engaging tongue `are adapted to bear against the door casing at spaced points to hold the said door engaging portion in resilient frictional engagement with the said door.
