T0 aZZ whom it may concern:

Be it known that I, THEODORE THISTLE- woon, a citizen of the United States, residing at Houston, in the county of Kentand State of Delaware, have invented certain new and useful Improvements in Adjustable Shade- Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

For window-shade rollers I have produced an improved sheet-metal bracket having a pair of longitudinal slots in alinement, each slot having its edge formed with teeth, the teeth of one slot being on its upper edge and the teeth of the other slot on its lower edge and the inner end of the outer slot terminating in a recess below its lower edge and the inner end of the inner slot terminating in a recess above its upper edge, whereby the fastening nails or screws in the slots are caused to be engaged by the upper and lower teeth of each slot to hold the bracket to its fixed adjustment and allow it to be tilted upward at its outer end to free the teeth to allow the bracket to slide to bring its recesses to register with the screw-heads to allow the bracket to be removed without removing the screws. This construction renders it convenient to adjust the bracket to suit the length of the' shade-roller without trouble with the fastening-nails, and the arrangement of the teeth is such as to cause them to bite into the upper and the lower sides of the fastening-screws under the weight of the roller and curtain.

The accompanying drawings illustrate my improved roller-bracket in perspective in Figure 1. Fig. 2 shows the bracket with the teeth of each slot in engagement with the shanks of the fasteningscrews. Fig. 3 shows the bracket tilted on its fastening-screws. to allow it to be moved in either direction to adjust it or to remove it when the slot-recesses register with the heads of the fasteningscrews. Fig. 4 is a view showing the bracket in the position to allow it to be removed from its fastening-screws.

The bracket is formed of a single piece of sheet metal having the angle end provided with a hole to receive the bearing-pin of the shade-roller in the usual way. The bracket has a pair of slots 1 1 in alinement, the upper edge of one and the lower edge of the other slot formed with teeth 2 2, the inner end of the slot at the outer end of the bracket terminating in a recess 3 below the lower edge of the slot, while the inner end of the slot at the inner end of the bracket terminates in a recess 4 above the lower edge of said slot. A screw or nail 5 fastens the bracket in each slot, the width of the slots being a little greater than the screw or nail shanks to allow the bracket to be freely slid on and over them in adjusting and setting them to the length of the shade-roller, while the recess at the end of each slot so enlarges it that it allows'the bracket to be removed over the heads of the fastening-screws when the bracket has been moved outward to its limit to cause the recesses to register with the screw-heads, as in Fig. 4. In the upward tilting of the bracket it will be noted that its fastening-screw of the outer slot will serve as the fulcrum on which the bracket is rocked to depress its inner end, as in Fig. 3, to allow it to be slid.

Another feature of novelty is the placing of the teeth on the lower edge of the inner slot so that they will be caused to bite into the screw-shank, and thus effect a double security of the bracket against endwise movement when set. It will be understood that the bracket for the other end of the roller is of identical construction and fastened in the same way, and that the teeth are made sharp to bite into the metal shanks of the fastening nails or screws, and that the weight on the bearing end of the bracket has the effect of constantly tending to lift the inner end of the bracket, and thereby maintains the en gagement of the teeth on the lower edge of the inner slot with the under side of the fastening-screw and the upper teeth of the outer slot in engagement with the upper side of the fastening-screw.

I claim- 1. As a new article of manufacture, a shade-roller bracket, formed of a single piece of sheet metal having an angle end for the roller-bearing, a pair of slots in alinement, the slot at the angle end terminating at its inner end in a recess at its lower edge, and having its upper edge formed with teeth, the other slot terminating at its'inner end in a recess at its upper edge and having its lower edge formed with teeth.

2. As" anew article of manufacture; a In testimony whereof I have signed my shade-roller bracket formed of a single piece name to this specification in the presence of 1 of sheet metal having an angle end for the two subscribing Witnesses.
