Recesses are thus formed to My invention will be better understood by refreceive the opposite ends of the headrail which Fig. 1 is a front elevational view-of a Venetian be presently described. As shown in Fig. 1 of the blind showing the opposite endsof the head rail drawing, brackets v i l. and I2 are similar, that is, extending into recesses in brackets fastened to they are complementary to each other and conative position; of any desirable number. of parts or of any de- Fig. 3 is a cross sectional view on the line 3-3 siredinaterial, for purposes of illustration, asinof Fig. showing the end of the head rail in podicated more clearly in Figs. 2 and 3, it con- 0 sition in the recess formed in the bracket, the sistsof a sheet metal stamping of a ngular form, securing device being in its operative position; one leg of .which'is formed toprovide an interand "mediate body portion, I3, laterally extending Fig. 4 is a cross sectional view on the line flanges l4 and i5, and an endflange IS, the 4+5 of Fig. 3, showing one means of attaching flanges forming a recess to receive the end por- 5 5 the securing device to the bracket. tion of the head rail. From'the structure thus described it will be noted that the end portion of the head rail may be inserted between flanges I l and Iii and is limited in its inner movement by the flange IS. The body portion l3 may be of such a length that head rails of various widths may be inserted in the recess.

For the purpose of securing the end of the head rail firmly in position, the body portion is provided with a downwardly extending leg or arm I! having an inwardly extending lug is which is parallel to the flange l5 and perpendicular to a plane passing through flange l5. As shown in the drawing, the lug I 8 is spaced from one end of the flange l5 and the intermediate body portion I3 is provided with a notched opening IQ for permitting one arm of the securing device Zil to be forced into the portion of the wooden head rail extending into the recess.

While securing device 20 may be movably mounted upon the leg portion l! or upon-the lug IS in any desired manner to secure the end of the wooden head rail firmly in place, such as by means of a rivet or the like, as illustrated in Fig. 4 of the drawing, an annular flange is punched from securing device 2!] a short distance from one end thereof as indicated by the numeral 2!, which is inserted through an opening in lug I8, the outer end of the flange having a curled edge to pro Vide a pivotal connection between securing device 20 and lug l 8. A cutting portion 22 and a handle portion 25; are thus provided, the handle portion having a lug 24 by means of which it may be conveniently operated. As shown in the drawing, when the handle portion of the device is raised sufiiciently to permit theend portion of the head rail to be inserted in the recess formed by flanges l l, l5 and Hi, the end of the cutting portion is substantially flush with the outer side of the body portion l3. After the end portion of the head rail has been inserted in place, the handle 23 is moved downwardly, forcing the cutting portion 22 through the opening l9 and into the wood, cutting a groove in the portion of the head rail extending into the recess, and the weight of the handle will have the tendency to maintain the end portion of the head rail firmly in the groove which has been cut. The fastening device may be released from the head rail when desired, by raising the handle portionof the device attached to each bracket.

My improved bracket may be attached either to the side wall of the window frame as shown, or may be attached to the front wall of the frame. For this purpose the body portion I3 is provided with apertures 25 through which screws may be inserted to attach the bracket to the side wall of the window frame, and flange It is also provided with apertures 26 through which screws may be inserted to attach the brackets to the front wall of the window frame.
