DOOR OR WINDOW CASEMENT-CATCH u Filed March so, i951 L W.C.'Marsha// ATTORNEY Patented Nov. 29, 1932 lbeendetrarnr `SPICE( Application led March 30, 1931. Serial No. 526,52.

The invention relates to a door or window Casement holder, and more especially to a door or window easement catch.

lllhe primary object of` the invention is the provision of a holder or catch of this chan actor, wherein a swingng door or window Casement can be latched or held caught in open position, the holder or catch being of novel form -so that on the swinging of either the door or Casement, the latter will not become damaged or marred by impact or otherwise.

Another object of the invention is the provision of a holder or catch of this character, which is extremely simple in construction, thoroughly reliabln and eflicient in its purpose, Vreadily and easily Vapplied to a support or removed therefrom, neat and attractive in appearance, strong and durable, and inexpensive to manufacture.

lVith the above and other objects in view, the invention consists in the features of conw struction, combination and arrangement of r parts, as will be hereinafter more fully de scribed in detail, illustrated in the accompanying drawing which discloses the pre ferred embodiment of the invention, and

pointed outin the claim hereunto appended.

ln the accompanying drawing Figure l is a vertical sectional elevation through a door or window easement holder or catch constructed in accordance with the invention, showing by dotted lines the knob of the door or caseinent engaged therewith, the door being fragmentarily shown in dotted lines. i Y

Figure 2 is an elevationof the'holderor catch.

Figure 3 is a detail plan view of the buffer associated with the holder or catch.

Similar reference characters indicate cor-- responding parts throughout the several views in the drawing.

Referring to the drawing` in detail, the

c; catch or holder comprises preferably a face made fast to the plate 5 through the medium right in any suitable manner, to confront the knob of a door for window easementl when either the door or window Casement is swung to open position and in this instance, said plateis secured by screws 6, as is `clearly shown in Figure 1 of the drawing. Superirnposed eentrallv of this plate 5 is a resilient disk 2' having a raised convex buii'er center 8, which is adapted to protrude through the catch or holder proper hereinafter fully described. Y The catch or holder prop-er'comprises a pair of spaced opposed resilient jaws 9, these forming the end portions of a substantially U-shap-ed frame 10, the medial portion of which is straight and provided with a Ceni tral aperture or hole 11 for accommodatingthebuferS, said straight media-l portion being superimposed upon the disk '.7 c and is ofV fasteners 12 passed through said medial straight portion 11, the disk 7 and securedinV the plate 5. rlhe jaws 9 have outwardly flared free end portions 13 with outwardly curled extensions 14, while said jaws between th-e portions 13 and the medial straight portion 10 are outwardly bowed, as at 15, to constitute a seat therebetween for the knob 16 ofa swinging door or window casing, a portion'of the door being indicated at 17 in Figure 1 ofthe drawing. 1

In the use of the holder or catch, when the door or window casing is swung to open position, the knob16 will be forced between the portions 13, causing the automatic spreading of the jaws 9, whereby the latter will be snapped into engagement with the knob on the contact thereof with the buffer 8 andbecome seated in the outwardly bowed portions 15 of said jaws, thus holding the door or window Casement inV open position. On'k swinging the door to closed position, the knob 1,6 willl ride out from betweenthe resilient jaws Q of the catch or holder proper, kthe buffer 8 being designed to prevent damage to the knob when forced into the catch or holder proper, as will be clearly apparent.

What is claimed is 4 A door or' window easement catch comprising a flat base plate having a central substantially circular-shaped seat in the outer face thereof, a resilient buffer engaged in said seat and having a conveXed exposed outer face, an open resilient clip having a medial portion provided With an openingof less diameter than the seat and accommodating a major portion of the oonvexed outer surface of said buffer and also superimposed upon the hase plate With the opening matching the seat to retain the buffer therein,

means detaehably seouring the clip to thel base plate and disposed at opposite sides of the seat therein, and outwardly flared terminals on the clip at the open side thereof and l having outwardly and inwardly curled free ends.

In testimony whereof We aflix our signatures.
