REINFORQEMENT Filed Oct. 13, 1955 IN VEN TOR.

zjhm/z/ fw States REINFORCEMENT Alexander L. Clement, Holyoke, Mass.

Application October 13, 1955, Serial No. 540,258 1 Claim. (Cl. 20-92) and bottom rails of a wood window sash frequently become loose due to the failure of the connections therebetween. To reinforce the connection, a novel reinforcing bracket is provided which strengthens and makes the sash rigid.

The novel bracket is formed from sheet metal to have a flat leg for lying against the face of the end portion of the transverse horizontal member of a sash or the like and a leg for lying against the face of an end portion of the vertical side member thereof with means for securing the legs to their respective members.

All of the above cited objects, I accomplish by means of such structure and relative arrangement of parts thereof, as will fully appear by a perusal of the description below and by various specific features which will be hereinafter set forth.

To these above and other ends and with the foregoing and various ancillary features and advantages and objects of my invention as will become more readily apparent as the description proceeds, my invention consists in certain features of novelty, and arrangement of parts as will be hereinafter more particularly pointed out in the claim hereunto annexed and more fully described and referred to in conjunction with the accompanying drawings wherein:

Fig. 1 is an isometric view showing the reinforcing bracket of the invention;

Fig. 2 is an isometric view of the bracket shown in Fig. l, secured to the corner of a sash or the like; and

Fig. 3 is an elevational view of the sash portion shown in Fig. 2.

Referring to the drawings more in detail, the novel features of the invention will now be fully described. In describing the invention, reference will be made to a window sash but it will be understood that the bracket is adapted for window screens, storm sash, or the like.

A bracket 2, shown in Fig. 1, which embodies the novel features of the invention, is formed from sheet metal to have a vertical leg 4 and a horizontal leg 6 disposed in right angular relation.

The leg 4 is located at one end of the horizontal leg 6 which is necessary, as will appear. Adjacent edges of the legs are joined by a curve 8, as shown, for strength. The leg 4 is provided with a plurality of openings 10 for screws and a plurality of pointed prongs 12 are struck up from the leg 6 for impinging the wood of a sash.

As shown in Figs. 2 and 3, the vertical side member of a sash is represented by 14 andthe top or bottom aterit:

horizontal or transverse member of said sash is represented by 16. A portion of a light of glass is represented by 18. The sash, as is usual, is made from wood members.

The outside surfaces of the members 14 and 16 are recessed or formed to receive the legs 4 and 6 of the bracket in such a way that the outer surfaces of said legs are flush with the surface of said members, as shown.

The prongs 12 of the bracket are driven into the member 16 so that the said leg is secured thereto. Screws 20 extend through the openings 10 of leg 4 of the bracket for securing said leg to the member 14.

Thus, the member 14 is held to the member 16 against outward movement relative thereto and against longitudinal movement away therefrom.

Reinforcing brackets may be secured to all four corners of a sash or the like so as to strengthen the sash at its corners, where looseness of joints commonly develops.

The reinforcing bracket is easily applied to a window sash or the like, and functions to strengthen the sash where the connections between the members has become weakened or may be applied to sash as they are manufactured.

While I have illustrated and described the invention as embodied in a specific arrangement, I do not intend to be limited to the details shown since various modifications and structural changes may be made without departing in any way from the spirit of the invention.

Without further analysis, the foregoing will so fully reveal the gist of my invention that others can by applying current knowledge readily adapt it for various applications without omittingfeatures that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the claim below.

What it is desired to claim and secure by Letters Patent of the United States is:

A unitary reinforcing bracket for the jointure of the vertical side and horizontal end members at the corner of a window sash having coplanar outer surfaces and adapted for overlying the horizontal face of the horizontal member at the end of the sash and the coplanar related faces at the outer sides of said members comprising, a member having an elongated horizontal leg and an elongated vertical leg extending at right angles from said horizontal leg adjacent one end portion of one 1ongitudinal side edge thereof, said vertical leg having a transverse width relatively less than the length of the horizontal leg, and a portion of the inner longitudinal side edge of said vertical leg adjacent said one longitudinal edge of the horizontal leg curving into said one edge, the face of the horizontal leg being provided with a plurality of sharp prongs struck up therefrom and being adapted for overlying the horizontal end face of the end member of a sash with said prongs impinging said member, and the vertical leg adapted to overlie the coplanar related faces of the horizontal and vertical members and. being provided with openings for screws extending into said members.
