WINDOW-SHADE.

SPECIFICATION forming part of Letters Patent No. 557,771, dated April 7, 1896.

Application filed November 26, 1395. Serial No. 570,194. (No model.)

To (tZZ whom it may concern.-

Be it known that I, JOHN G. J. Davrs, a resident of Augusta, in the county of Richmond and State of Georgia, have invented certain new and useful Improvements in indow- Shades; 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 artto which it appertains to make and use the same.

My invention relates to an improvement in window-shades, and more particularly to such in which the shade-roller is adapted to be raised and lowered, the object of the invention being to produce a window-shade of the class above mentioned which shall be simple in construction, comparatively cheap to man ufacture, which shall be applicable to any window, which shall be ornamental in appearance, and which shall be effectual in all respects in the performance of its functions.

lVith these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view illustrating my improvements. Figs. 2, 3, and at are detail views. Fig. is a view illustrating a modification of the upper roller.

A represents a window frame or casing, to the top of which brackets 1 1 are secured for the reception of the journals of an upper spring-roller B. This roller is made in telescopic sections 2 2 3, so as to make it extensible and readily adjustable to windows of different widths. The centralsection orbody portion 3 of the roller B may be made of brass or other pipe and the end sections 2 2 made to fit over the ends of this tubular body portion 3. One end section 2 may be secured to the body portion 8 when the device is first manufactured and the other end section may be left loose, so that it can be moved more or less on the bodyportion 3 to adjust the roller so as to properly fit brackets on the windowframe to which a particular roller is to be attached. The end sections will preferably be secured to the body portion of the roller by means of screws 1. The end sections 2 of the roller B may be made of ornamental brass castings, and each end section may be made in one or in several pieces, as desired, or they might be made of wood covered with decorative metal shells when cheapness of production is desired. The roller 13 is provided with two shafts 5, one mounted in each end section 2, and havingprojecting ends 6 adapted for the reception of key 7. The projecting ends 6 of the shafts 5 may be normally covered by removable ornaments 6. Springs 8 surround the shafts 5 and are connected, respectively, thereto and to the roller B. Each shaft is made with notches for the reception of pivoted dogs 9.

Each end section 2 of roller B is made to form a drum 10, on which tapes 11 are adapted to wind, one end of each tape being inserted in a slot 12 in the respective drums, and each drum is provided with a collar or flange 13 to prevent lateral displacement of the tapes. The lower ends of the tapes 11 are attached to spring-arms 14, secured to abar 15 at points near the ends of the latter. To the ends of the bar 15 brackets 16 are secured by means of clips 17, for the reception of a spring shaderoller 18, to which lattera shade 19 is secured. Pads 20 are secured to the ends of the bar 15 and adapted to bear against the window frame or casing and prevent the same from being marred, and to prevent noise which would otherwise be occasioned by the engagement of said bar with the window-frame when the shade is moved or shaken by the wind or otherwise. It will be seen that bar 15 and shade 19 of any desired size can be employed. In fact the shade 19 may be even wider than the upper roller B, if desired. The upper roller may be mounted in the brackets ordinarily employed for supporting spring-roller shades and the lower roller connected therewith without in the least marring or defacing the window-frame. In fact no additional devices are aifixed to the windowframe.

I prefer to cover the bar 15 with shade-cloth of the same color as the shade, so that it will have the appearance of being a part of the latter, and the tapes 11 will also preferably be made of the same material as the shade. A cord 21 will be attached to each bracket 16 on the shade-rollerbar, by means of which to bodily raise and lower said shade-roller.

The springs of the upper roller 13 will be so adj usted by means of the key 7, above referred to, as to be sufficiently stronger than the spring of the lower or shade roller that when the shade is pulled down the upper roller will not be aifected. This is a feature of some importance in the construction of window-shades of the class to which my invention relates, because the special, and in some cases intricate, contrivances heretofore employed for this purpose are avoided and the proper adjustment of the rollers relatively to each other can be accomplished by any one.

It is apparent that the lower roller, carrying the shade, can be readily lowered by pulling on either of the cords 21, and that the shade will always be lowered evenly and without the slightest difficulty.

If a more economical upper roller B be desired than that above described, it may be constructed as shown in Fig. 5. In this figure an ordinary wooden spring-roller is shown, except in this case the spring-barrel 23 is extended entirely through the roller and two springs and ratchet devices are employed. This roller will also be provided with sleeves or drums 24 for the reception of the tapes and with collars or flanges 25 to prevent the lateral movement of the latter.

My improvements are very simple in construction, comprise few parts, and are efiectual in all respects in the performance of their functions.

Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details of construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with an upper roller comprising a central section and end telescopic sections, the end sections being provided with spring and ratchet devices and tapes secured to and adapted to wind on said end sections, of a bar secured to said tapes and a spring-actuated shade carried by said bar, substantially as set forth.

2. The combination with an upper springroller adapted to be attached to a windowframe, of a bar, a spring-actuated shade-roller carried by said bar, a shade attached to said shade-roller, tapes attached to said bar and adapted to wind on the upper roller, and a removable device whereby to so regulate the tension of the spring in the upper roller that said spring will, at all times, be sufficiently stronger than the spring of the shade-roller that when the shade is pulled the upper roller will not be turned, substantially as set forth.

3. The combination with an upper roller to be attached to a window-frame, said roller comprising a central bodyportion and adj ustable end sections, of a shaft in each end section, each shaft projecting beyond the end of the roller and adapted for the reception of a key, a sprin gin each end section, said springs being attached respectively to the shafts and the roller, ratchet devices to engage said shafts, tapes adapted to wind on said roller, a bar attached to said tapes, brackets secured to the bar, a spring shade-roller mounted in said brackets, a shade secured to said shaderoller and cords attached to the ends of said bar, substantially as set forth.

In testimony whereof I have signed this specification in the presence of subscribing witnesses.

JOHN G. J. DAVIS.
