MEANS FOR SUS TAINING AND ADJUSTING WINDOW-SHADES SPECIFICATION forming part of Letters Patent No. 710,079, dated September 30, 1902.

Application filed June 13, 1901. Serial No. 64,451. (No model.)

.To all whom, it Wtcty concern:

Be it known that I, ANTHONY SERAFINSKI, a subject of the Emperor of Russia, residing at Jersey City, in the county of Hudson and State of New Jersey, haveinvented certain new and usefulImprovements in Means for Sustaining and Adjusting Window-Shades, of which the following is a specification.

This invention relates to means for sustaining and adjusting window-shades; and it has for its object to provide an improved device of this class whereby a window-shade may be bodily adjusted vertically of the windowframe and may be maintained positively in position of vertical adjustment and against lateral and forward and backward movement.

By means of my improvements the windowshade may be brought into any desired position with relation to the area of the window, and the shade proper may be raised or lowered in the customary manner by rolling or unrolling the same from the roller.

In the drawings, Figure 1 is an inside e1e-' vation of the window-frame provided with a window-shade and with theim proved featu res constituting my invention. Fig. 2 is aside elevation of the same. Fig. 3 is adetail horizontal sectional View taken upon the line 00 00, Fig. 1. Fig. 4 shows an end elevation of the Windlass or pulley.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring to the drawings, in carrying out my invention I provide vertical tracks or guides 1, which are arranged at either side of the window-frame 2 and with which the ends of the shade-roller 3 are slidably connected, as at 4, permitting the raising and lowering of the shade-roller and the shade proper,5,which is wound upon the same in the customary manner. The shade-roller 3may be of the common Hartshorn or similar type, which enables the shade proper to automatically maintain any desired rolled or unrolled condition and to be automatically wound upon the roller. Thewindow-shade is directly supported by means of flexible devices 6, each of which connects at one end with the shaderoller and at the other with a Windlass or pulley 7, upon which said flexible devices may be wound and which embodies means 8 for automatically locking the Windlass or pulley against-rotation to maintain the roller 3 in po-' sition of vertical adjustment. The Windlass or pulley 7 is also provided with a supplemental flexible device 9, whereby said windlass or pulley may be operated to raise the shade-roller or permit the sameto be lowered. The Windlass 7 is preferably mounted upon the window-frame at the top of the same, as illustrated.

In the preferred formof construction the guide devices 1 consist each of a verticallyarranged rod or wire, the ends of which are clamped in bracketsll secured, respectively, at the top and at the bottom of the windowframe and at one side of the same. The roller 3 is provided with the customary end bearings 12, which are fitted in brackets 13, which are slidably mounted upon the rods or wires 1, so that the roller 3 is only permitted a vertical movement and is prevented from displacement or swinging movement laterally and toward and away from the windowframe. The brackets 13 are provided with inwardly-projecting sockets 14, in which the end bearings 12 of the roller fit, and said sockets 14 embody binding-screws 15, whereby said end bearings may be firmly connected with the brackets 13. The brackets 11 also embody sockets 16, in which the ends of the wires or rods 1 are secured by means of binding-screws 17.

The Windlass 7 is provided with a baseplate 18, which may be readily secured to the top of the window-frame, and two spaced arms or brackets 19 project outwardly from said baseplate and carry a shaft 20, upon which the pulley or Windlass body 7 is rotatably mounted. The pulley 7 is provided with three annular peripheral grooves, in the endmost of which, 22, the flexible devices 6 are adapted to be wound and in the intermediate of which grooves 23 the flexible device 9 is adapted to be wound. From the pulley 7 the flexible devices 6 pass each about a guide-pulley 24, which guide-pulleys are arranged in spaced relation at the bottom of the base-plate 19, and thence pass about guide-pulleys 25, which are carried by the brackets 11 at the inner sides of the same. A guard'26 is provided for each of the guidepulleys 24, and each of said guards 26 consists of an outwardly-projecting finger 27,

which is secured to the base-plate l8 and between which and the respective pulley the flexible device 6 passes. The lower end of each of the flexible devices 6 is directly connected with one of the brackets 13, and the flexible devices 6 are of proper length and are properly wound upon the pulley 7 to maintain the roller 3 in horizontal position. I also provide a guard 28 for the flexible device 9 to prevent the same from running out of the intermediate grooves of the pulley, and said guard consists of a curved arm 29, which is slightly spaced from the lower peripheral portions of the pulley 7 and is provided with an elongated slot 30, through which the flexible device 9 passes.

The means 8f0r lockingthe pulley? of the Windlass to prevent the lowering of the window-shade consist of a plurality of pivoted dogs 31, which are carried at one end of the pulley 21 and are adapted to take into a notch 32, formed in the shaft 20, by gravity when the pulley 7 is slowly revolved, but which dogs by their centrifugal force will be prevented from engagement with said notch when the pulley 21 is speedily revolved.

The operation and advantages of my improved means for sustaining and adjusting window-shades will be readily understood. The shade, consisting of the shade proper and the shade-roller, may be adjusted to any desired height upon the window-frame along the guides 1 by means of the flexible device 9, the locking means of the pulley 21 serving to lock theshadeindesiredposition. Theshade may be released from locked position by pulling violently upon the flexible device 9 and then allowing the shade to instantly fall, so that the dogs upon the pulley are by centrifugal force maintained out of engagement with the notch in the shaft of the pulley. The operative area of the shade proper, 5, may be regulated by unrolling the shade proper from the roller or rolling the same thereon in the customary manner, and it is thus possible to provide any portion of the window with the desired area of shade proper to suit all conditions of passage of light and air through the window.

tained in their movement by the guide-pulleys 24: and 25 and the guards 26, and the flexible device 9 is prevented from displacement from its groove in the pulley 21 by the guard 28.

The entire device may be readily attached to a Window-frame and is very simple in construction and is operated entirely by the flexible device 9 and by a curtain-cord or other device such as customarily employed.

I do not desire to be understood as limiting myself to the details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement in the adaptation of the device to various conditions of use without departing from the spirit and scope of my invention and improvements. I therefore reserve the right to all such variation and modification as properly fall within the scope of my invention and the terms of the following claims.
