I ROLLER SHADE ATTACHMENT I Filed Oct. 12, 1934 INVENTOR ATTORNEY Patented Dec. 3, 1935 UNITED STATES PATENT OFFICE 1 Claim.

The invention relates to a roller shade attachment and more especially to a shade stop.

The primary object of the invention is the provision of an attachment of this character, wherein the same is carried at the free end of a roller shade so that when the latter is wound upon its roller the shade will be prevented from overwinding and thus such shade will be assured of smooth and tight winding upon the roller.

Another object of the invention is the provision of an attachment of this character, wherein should it happen that a shade is snapped suddenly by the spring tensioned roller carrying the same, the said shade will be arrested and thus avoid the unwinding of the spring within the roller and at the same will limit the winding action of the shade upon the roller, the attachment being ornamental in effect.

A further object of the invention is the provision of an attachment of this character which is simple in construction, thoroughly reliable and efficient in its purpose, readily and easily applied to a window shade, neat and attractive in appearance, durable, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation of a shade, showing the attachment constructed in accordance with the invention applied thereto.

Figure 2 is an edge elevation.

Figure 3 is a plan view of one part of the attachment in blank formation.

Figure 4 is a view similar to Figure 3, showing a slight modification.

Figure 5 is a fragmentary edge elevation.

Figure 6 is a fragmentary plan view of a further modified form.

Figure '7 is an edge view thereof.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a roller shade for a window or the like which is of conventional kind adapted to be wound on and unwound from a spring tensioned roller B of well known construction, the

said roller being mounted at each end in a bracket 10 for the placement of the shade in position with respect to a window or the like. The shade A, at its free end, is provided with a casement H in which is fitted the shade stick I2 and at this end 5 of the shade A is applied the attachment constituting the present invention and hereinafter fully described.

The attachment comprises a pair of angle pieces l3, each formed from metal and cut and 10 shaped to present a pleasing design, as at l4. Each piece l3 has the bendable tongue l5 which is turned about the casement ll carrying the stick l2 at one corner of the shade A to lie at the inner side of such shade and the tongue I 5 being 16 of a width corresponding substantially to the width of the casement ll, while passed through the said tongue and the component part of the piece I3 is a fastener [6 for the securing of such piece in place, as shown in Figure 1 of the draw- 20 ing. It is, of course, understood that the pair of pieces [3 are worn by the shade at the corners of the free end thereof, this being apparent from Figure 1 of the drawing.

In Figures 4 and 5 of the drawing there is 25 shown a slight modification, wherein the tongue I? is formed at one end edge of the piece l8, while in Figures 6 and '7 there is shown a still further modification, wherein the piece H! has struck therefrom bendable spurs or teeth 20, 30 which bite into the shade A and the stick l2 as confined within the casement II, and in this manner the piece I9 is made firm and secure to the shade.

It will be apparent that when the shade A is 35 wound upon the roller B the pieces l3, l8 or [9 will abut the head of the window, as at 2| in Figure 2 of the drawing, to avoid the overwinding of the shade upon the roller and also to effect the tight and smooth winding of the shade upon 40 said roller.

What is claimed is:

In a window shade attachment a body piece for fastening to a window shade and having a portion which runs off at substantially a tangent 45 to the roll of fabric of the shade at the point where its attachment to the shade contacts that portion of the shade which is already wound on a roller and such portion being of a length enough in the direction of movement of the shade 5 to contact with a window casing at its top for limiting the winding of the shade upon the roller.
