I Patented Nov. 13, 1906.

Applioationfiled October 26, 1905. Serial No. 284,433.

To all whom, it may concern:

Be it known that I, JOHN J. DENNIS, a citizen of the United St ates, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Adjustable Shades for Windows or the Like; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference thereon, which form a part of this specification.

This invention relates to improvements in adjust able shades for windows or the like, and more particularly to a shade adapted to cover either the upper or the lower half of the window or opening, as preferred.

Heretofore it has been sought to attain the ends accomplished by this invention; but inasmuch as the supporting cords or wires up on which the shade has hung have usually wound upon the shade-roller at one place the devices have proved unsatisfactory and frequently injure the shade.

The object of this invention is to afford a cheap, simple, exceedingly durable, and easily-o erated shade-hanger whereby the shade can e quickly and evenly adjusted to cover a part of the window and to permit a part to remain uncovered either at the top or the bottom of the window or at both the top and the bottom, as preferred.

It is also an object of the invention to afford a construction on which the supporting cords or wires for the shade will roll evenly upon the shade-roller and in rolling will distribute themselves for practically the entire length of the roll, thus retaining the uniformity of diameter necessary to insure the shade rolling evenly upon the roll.

It is a so an object of this invention to afford an extensible shade stick or rod in combination with suitable supporting means adapted to be quickly and easily adjusted to suit any width of shade and provided with means for readily attaching the supportingcords thereon.

The invention consists in the matters hereinafter described, and more fully pointed out half thereof. Fig. 2 is a view in elevation of an extensible shade-rod embodied in my invention. Fig. 3 is afragmentary view, partly in section, of a modified form of the shade rod or stick. Fig. 4 is an enlarged transverse section taken through the curtain-roll with the. curtain rolled thereon. Fig. 5 is, an enlarged fragmentary elevation of the shade stick or rod, illustrating the means for attaching the cord thereto. Fig. 6 is a similar view with the cord-attaching clip removed. Fig. 7 is a section taken on line 7 7 of Fig. 5. Fig. 8 is a section taken on line 8 8 of Fig. 5. Fig. 9 is a section taken on line 9 9 of Fig. 2. Fig. 10 is a section taken on line 10 10 of Fig. 3. Fig. 11 is a perspective-view of an attaching-clip for engaging the cords to the roller.

As shown in said drawings, A indicates a spring curtain-roll of the usual or any desired construction adapted to be secured to the top of the window B or the opening to which the curtain is to be applied in the usual or any suitable manner and acting au-.

tomatically to .roll up the curtain when actuated. Centrally engaged upon said roller, as shown, is an attaching-clip C, comprising, as shown, a piece of sheet metal bent to afford a hook c and provided on the under side with one or more downwardly-turned prongs c, as shown in Fig. 11, which are driven into the roll. Secured in said hook c, as shown in Figs. 1 and 11, is a cord, such as a wire picture-cord or any suitable flexible connection 0 the middle of which lies in said hook, which is closed down thereon, so that the ends of the cord depend therefrom to a length usually greater than half the height of the window or opening. The ends of said cords are secured to the opposite extremities of the curtain stick or rod D as shown in Fig. 1'.

Said rod or stick may of course be construct-- ed in any suitable manner; but conveniently the same is concave on its inner side or that which contacts with the roll when the curtain is raised. Said stick, as shown in Figs. 2 and 3, is adjustable as to length to enable the .same to be adjusted for use with curtains of different widths, and, referring to Figs. 2, 5, and 9, said stick comprises a plurality of strips of sheet metal D and D, on theinner ends of each of which is secured a metallic clip (1, which engages over and around the other to enable said strips or sections to slide in said clips, as indicated in dotted lines in Fig.2,

though at all times held straight. As shown, the ends of the cord 0 are detachably engaged on the ends of the stick by means of metallic socket pieces or clips D These, as shown, each comprise a piece of sheet metal folded and cut to afford a socket-piece, one side of which, as shown, is concave and the other convex and in which the reduced ends (1 of the curtainstick fits closely. The clips are shaped to afford an oblique downwardlyinclined upper corner, as shown in Fig. 5, and

downwardly or turned over, affording a rounded edge to slide within the groove afforded for the downturned edge of the outer section. In this construction the cord ends may be secured to the ends of the stick by providing an aperture through the upper edges 61 or d in said sections and passing the ends of the cord therethrough and knotting the ends before the edges are rolled down.

A curtain E of the desired length, usually approximately half the height of the Window or opening, is provided with a hem at its up per edge adapted to receive the stick therein, as is usual, or is otherwise secured upon the stick and may be provided 'with the usual bottom stock F.

The operation is as follows: The curtainroller of course operates as is usual. When released, the spring 0, causes the roller to re volve, winding the cord end 0 around the same, as shown in Fig. 1, in opposite spirals from the middle toward the ends of the roller and elevating the curtain thereby. The curtain may of course be stopped in the usual manner by checking the same at any point desired, and the shade can be arranged to cover that portion of the window it is desired to obscure thereby. Should it be necessary or desirable to uncover the greater part of the window, the curtain is drawn upwardly on its roller by the continued rotation thereof until the concave side of the stick is brought in contact with the roller, as shown in Fig. 4, fitting over the spirally-wound cord and but slightly increasing the diameter. The continued rotation of the roller causes the curtain E to be rolled around said stick and roller, and, if desired, the entire windowopening may be exposed.

From the construction described it will be observed that devices embodying my invention may be applied in lieu of the usual curtain to any window provided with the ordinary automatic spring-roller or any kind of roller, and inasmuch as the ends of the cord 0 are of equal length and connected at their ends with the ends of the stick the curtain must at all times wind true to the window and upon the roller. Furthermore, the curtain-stick, cord, and attachment may be manufactured in large quantities of standard sizes, and stock sizes may be very quickly applied to a curtain of any width, inasmuch as the stick is extensible. Thus light and air may be obtained from the upper part of the window without danger of injuring the curtain or exposure of the room to view from the outside.

While I have described my invention as embodied by fastening the middle portion of the cord centrally on the roller, it is obvious that said cord or two separate cords may be fastened at any suitable points upon the roller and stick to permit the cords to wind spirally on the roller, distributing the same with approximate uniformity thereover preliminary to the stick and curtain rolling thereon, and I do not purpose limiting this application for patent to the specific details of construction herein described, as obviously.

many details of construction and operation may be varied without departing from the principles of my invention.

I claim as my invention- 1. A shade-attaching mechanism embracing a shade-roller, a clip secured centrally on said roller, a cord secured at its center on said clip and extending obliquely therefrom, an extensible curtain-stick engaged at its ends to the ends of said cord, saidcord being adapted to wind spirally on the roll for the entire length thereof.
