Specification of Letters Patent. Patented lVIay 13, 1919.

Application filed April 6, 1915. Serial No. 19,428.

To all whom it may concern Be it known that I, CARL JOSEPH, a citizen of the United States, and a resident of Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Hollow Slats for Window-Shades, of which the following is a specification.

This invention relates to a hollow slat for window shades. It is characterized by a main central portion with adjustable pulley supports, which latter have j ournaled therein pulleys for the shade adjusting cord. The invention in this instance is shown with a window frame and shade retainer. The lat ter is the subject matter of an accompanying patent application for adjustable shade or curtain retainer filed April 6, 1915, Serial Number 19,429.

In the accompanying drawings, Figure 1 represents a front elevation of the invention with a window frame and shade with its appurtenances; Fig. 2 shows a left hand side view of Fig. 1; Fig. 3 is a top plan view of Fig. 1; Fig. 4 represents an enlarged fragmentary portion of Fig. 1 partly in section; Fig. 5 shows a left handview of Fig. 4 with the latter not sectioned; Fig. 6 shows a section as on the line 6, 6 of Fig. 4; Fig. 7 shows a side view of a modification partly in section; Fig. 8 shows an end view of Fig. 7 when not sectioned; Fig. 9 shows a side view of a further modification partly in section and Fig. 10 shows an end view of Fig. 9 when not sectioned. A window frame is indicated with the vertical members 20, 21, the top cross piece 22 and the window sill 25. A pair of brackets 26, 27 are fastened to the top cross piece 22. a A single pulley 28 with the sheave 29 is suspended from the bracket 26 anda double pulley 30 with the sheaves 31 and 32 is suspended from the bracket 27. A shade or curtain retainer 1s shown to comprise a U shaped hood 35 with the end covers 36, 37.

The end cover 36 has a central opening for a flanged roller 40, and a vertical slot 41. is formed in said end cover. The flanged roller 40 has formed therein the slot 42 which extends from its axial center to the periphery thereof. A U shaped wire 45 is pivoted in lugs 46 extendmg from the flanged roller 40. A shade roller is indicated at 50 with the rectangular pin 51 and the pivot 52. The pin 51 is located in the slot 42 of the roller 40 and the pivot 52 is has one end fastened to the roller 50 and is indicated as partly wound around the said roller. A hem pocket 56 is formed at the other end of the shade 55.

Within the pocket 56 is located a hollow slat having the main hollow U shaped central portion 60 with the vertical legs 6l.and 62. A guide hook end 63 is formed with the leg 61. At the opposite ends of the central portion 60 is adjustably telescopically carried the adjustable hollow U shaped pulley supports or portions 68. with the legs 69 and 70. A pulley 71 is journaled at the outer end of each pulley support 68.

A bracket72 with the clamping rollers 73 and 74 is fastened to the vertical member 21, and the sill 25. An adjusting cord 7 5 has one end fastened to the sill 25, leads over one of the pulleys 71, extends through the hollow slat and then leads over the second pulley 71, after which it is engaged by the clamping roller 7 3.

A chain 80 has one end fastened to the end cover 36, leads over the sheave 29 of the single pulley 28, then leads over the sheave 32 of the double pulley 30. The chain 80 forms a loop 81 and returns over the sheave 31, and is then fastened to the end cover 37. A cord 82 has one end fastened to the loop 81 and leads under the clamping roller 74.

The U shaped hood 35 can be located in different levels by clamping the cord 82 in different positions with the clamping roller 74. By means of the adjusting cord 75 the shade 55 can be located in different positions with respect to the U shaped hood 35.

By means of the hollow slat, the shade when in its lowest position can be brought adjacent to sill 25. In Figs. 7 and 8 the invention is modified by eliminating the hollow adjustable U shaped pulley supports 68. The modification comprises a hollow U shaped portion 85 which issupported in the pocket 56. Pulleys like 86 are j ouirnaled in opposite ends of said portion 85, and the adjusting cord 75 extends through the portion 85 and contacts with the pulleys 86. In Figs. 9 and 10 the invention is further modified by using a hollow slat 88 supported in the pocket 56, and supporting in the slat 88 the adjusting cord 75.

Having described my invention what I desire to secure by Letters Patent and claim is:
