WINDOW-SHADE HANGER.

Specification of Letters Patent.

Patented Sept. 24:, 1907.

Application filed January 11, 1907. Serial No.- 351,877.

To all whom it may concern:

Be it known that I, FRED S. HAZELTON, a citizen of the United States, residing at Norton, in the county of Norton and State of Kansas, have invented certain new and useful Improvements in Window- Shade Hangers, of which the following is a specification.

This invention relates to window shades and fixtures therefor, whereby the shade roller may be adjusted to the window opening and the shade, or curtain, may be automatically wound upon, or unwound, from the roller while the latter is firmly and securely held in the adjusted position.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

While the invention may be. adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which: I

Figure l is a perspective View of a window and shade, or curtain, therefor embodying the invention. Fig. 2 is a horizontal section on the line of Fig. 1. Fig: 3 is an end view of the shade roller and mountings therefor. Fig. 4 is a view similar to Fig. 3 of the opposite end of the shade, roller and cooperating fixtures. Fig. 5 is a horizontal section of the righthand portion of the window frame on the line :r-rc of Fig. 1 showing the parts on a larger scale, the two positions of the toothed lock bar being shown by full and dotted lines.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The window shade and shade roller may be of any structural. type, the shade roller being of the variety actuated by a spring to automatically wind up the shade thereof.

A pulley 1 is provided at one end of the shade roller and is flanged and toothed in the groove formed between the flanges, the latter embracing opposite sides of a toothed bar 2 secured to a side of the window frame, or casement, thereby preventing longitudinal displacement of the shade roller. The toothed portion of the pulley 1 meshes with the teeth of the bar 2. A second bar 3 is arranged parallel with the bar 2 and is spaced therefrom a distance to receive the toothed portion of the pulley 1 between the two bars 2 and 3, the latter acting in the capacity of a keeper to hold the toothed portions of the bar 2 and pulley l in engagement at all times.

The bars 2 and 3 are secured to the window frame in any convenient and substantial way. A pulley 4 is fitted to the opposite end of the shade roller and is flanged at one side only, preferably the outer side, so as to engage with the upper side of a toothed bar 5 and assist materially in preventing longitudinal displacement of the roller.

The pulley 4 has a toothed portion 6 and a plain portion 7, the toothed portion 6 being adjacent to the flange and adapted to mesh with the teeth of the bar 5. A bar 8 is provided for cooperation with the pulley 4 and bar 5 and is mounted so as to receive a one-quarter turn. The bar 8 has a toothed edge, or face 9, and a plain face, or edge, 10, the two faces, or edges, being arranged approximately at a right angle to each other. In one position of the bar 8, its toothed portion 9 is in engagement with the toothed portion 6 of the pulley 4, whereas in the other position of said bar, its plain edge, or face 10, is in contact with the plain portion 7 of the pulley 4. A spring 11 cooperates with the bar 8 to hold the same in either one of its two extreme positions. The bar 8 acts in the dual capacity of a lock and a keeper, as a lock to hold the shade roller at the required elevation, and as a keeper to hold the toothed portion 6 of the pulley 4 in engagement with the teeth of the bar 5. When the plain portion 10 of the bar 8 is in engagement with the plain portion 7 of the pulley 4, the shade roller is free to move either up or down according to its direction of rotation which is governed by proper manipulation of the shade, or curtain, 12.

Upon pulling of the curtain, or shade 12, to unwind the same from the shade roller, the latter moves upward, provided it occupies a position at a point below its normal, or topmost position with reference to the window. When the shade roller is automatically actuated by its cooperating spring to wind the curtain, or shade l2 thereon, the result is to cause the shade roller to lower, or move downward since it turns to the left and the teeth of the pulleys 1 and 4 meshing with the teeth of the bars 2 and 5, effect a lowering of the shade roller as will be readily appreciated. When the shade roller has reached the required position, the movement of the bar 8 upon its pivots to throw its toothed portion 9 in engagement with the teeth 6 of the pulley 4, results in securing the shade roller in the adjusted position, it being understood that the pulley 4 is positively gripped upon opposite sides between the toothed portions of the I bars 8 and 5.

Having thus described the invention, what is claimed as new is:

raising or a lowering thereof, and a companion toothed bar arranged for cooperation with one of the toothed pulleys to secure the shaderoller in the adjusted position without interfering with the raising, or lowering of the shade.

2. In a window shade, the combination of a shade roller, flanged pulleys at opposite ends of the shade roller, each having, a toothed portion and one of said pulleys having in addition to the toothed portion, a plain portion,

toothed bars secured to the window frame and in mesh with the toothed portions of the aforesaid pulleys, and a combined keeper and lock bar having a toothed portion and a plain portion mounted to have the toothed portion thrown into or out of engagement with the toothed portion of the pulley having the plain and toothed portions, and to have its plain portion thrown into, or out of en gagement with the plain portion of the said pulley.

In testimony whereof I affix my signature in presence of two witnesses.

FRED S. HAZELTON.
