SHADE-ADJUSTM ENT.

. SPECIFICATION forming part of Letters Patent No. 668,800, dated February 26, 1901.

Application filed July 2, 1900 Serial No- 22342. kNo model.)

To all whom, it may concern:

Be it known that I, FRED H. KNAPP, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Shade-Adjustments, of which the following is a specification.

My invention relates particularly to shadeadjustments wherein are employed fixed vertically disposed guide rods, fixed pulleybrackets, and adjustable shade-roller brackets movable on said guide-rods.

My primary object is to provide improved interlocking guid e-rod brackets, pulley-brackets,and guide-rods, producing a cheap and simple construction wherein the guide-rods and pulley-brackets are more firmly held than heretofore.

In the accompanyingdrawings, Figure 1 is broken viewof a Window-frame, showing the guide-rods supported in an improved manner with the interlocking brackets in a given position; Fig. 2, a view at right angles to the view in Fig. l, but showing only one guiderod and the connected brackets; Fig. 3, a broken view showing the interlocking brackets supported in a different position; Fig. 4, a view at right angles to the view in Fig.3; Fig. 5, a perspective view illustrating the manner in which the rod, rod-bracket, and pulley-bracket interlock; and Fig. 6, a transverse section through one end of the guiderod, taken, as indicated, at line 6 of Fig. 5.

Fig. 1 shows the guide-rods supported from the opposed or inner faces of the jamb, while Fig. 3 shows the manner of supporting them from the outer faces or reveals thereof.

A A represent window-jambs; B B, upper guide rod brackets secured thereto; C C, pulley-brackets supported bythe brackets B B; D D, guide-rods interlockingly connected at their upper ends with said brackets, and E, one of the lower guide-rod brackets employed.

Each bracket B and B comprises a vertical part Cb, provided with screw perforations a, and a projecting horizontal part 0. provided with a rod-receiving perforation a and with lug or hook receiving recesses a a a. The bracket is preferably stamped from sheet metal, and the partais provided with lugs a which when bent at right angles to said part are in position to support or brace the part a Each bracket C and C comprises, preferably, a sheet-metal piece I), having stamped therefrom lugs 19, receiving the shaft of a cord pulley or roller b and provided also with a rod-receiving perforation b and a hook or lug b The metal is cut away between the lugs b to accommodate the pulley, as shown. The perforation b is preferably partially circular, as shown.

Each rod is recessed at its upper end to afford a flat vertical surface 0, the cut-away The lower end of the rod D is shown re-' duced in diameter where it enters the bracket E. Obviously, however, the rod is supported from the top brackets after the parts are interlockingly joined thereat, so that the reduc tion in size at E may be omitted, if desired.

In Fig. 2 the parts are shown so adjusted that the lug b engages the recess 0, The brackets are held in this relation by the rod being inserted from below into the perforation a then turned to register accurately with the perforation 19 then inserted through said perforation, and finally turned out of registration with said last-named perforation to lock the parts together. In the position of Figs. 1 and 2 the pulley-brackets project from the window-sash, forming outturned lateral projections from the guide-rod brackets. The pulley-brackets may be caused, however, to project toward the sash by causing the lugs 17 to engage the recesses a in which case the pulley-brackets form virtually-inturned lateral projections on the guide-rod brackets.

In the position of Figs. 3 and l the lugs 19 engage the recesses 006, and the pulleybrackets project in the same direction as the horizontal parts a thereby forming virtual elongations or extensions of the guide-rod brackets.

In use the curtain-roller brackets slide up and down on the guide-rods, being adjusted by cords passing over the pulleys b in a well understood manner.

Minor changes in details of construction within the spirit of my invention may be made. Hence no limitation is intended by the detailed description given, except as appears from the appended claims.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a shade-adjustment, the combination of a guide-rod bracket provided with a horizontal projection, a pulley-bracket supported on said projection, a guide-rod, and interlocking connection between said projection, pulley-bracket and rod, substantially as described.

2. In a shade-adjustment, the combination of a guide-rod bracket provided with a horizontal projection, having a vertical perforation, a pulley-bracket supported on said projection and having a perforation, and a guiderod having a head entering said perforations and serving to lock the parts together, substantially as described.

3. In a shade-adjustment, the combination of a guide-rod bracket having a horizontal projection, a pulley-bracket adj ustably supported on said projection, and a guide-rod interlockingly joined to said brackets and serving to hold the same in correct relationship, substantially as described.

4. In a shade-adjustment, the combination of a guide-rod bracket having a horizontal projection provided with a guide-rod-receiving perforation, a pulley-bracket supported thereon having a non-circular perforation, a lug and recesses on said brackets permitting adjustability, and a guide-rod having a head shaped to enter said non-circular perforation and provided with a shoulder, which serves after insertion and partial rotation to lock the brackets together, substantially as described.

5. In a shade-adjustment, the combination of a guide-rod bracket having a horizontal projection provided with a perforation, a flat sheet-metal pulley-bracket supported thereon and provided with a perforation, a guiderod provided with a head adapted to enter said perforations, said head and perforations being suitably shaped to permit insertion and partial rotation producing interlocking, substantially as described.

6. The combination of a guide-rod bracket provided with a circular perforation, a pulley-bracket supported thereon and provided with a non-circular perforation, and a guiderod having a head corresponding in shape to said non-circular perforation and provided with a shoulder which serves, after partial rotation of the rod, to lock the brackets toget-her and support the rod, substantially as described.

7. The combination of a sheet-metal guiderod bracket having a vertical attaching part and a horizontal projection, brace-lugs being stamped on one of said parts and bent to engage the other part, a pulley-bracket supported on said horizontal part, and a guiderod connected with said brackets, substantially as described.
