SAMUEL JASGUR, OF BROOKLYN, NEW YORK.

ATTACHMENT FOR WINDOW-SHADES.

New York, have invented certain new and useful Improvements in Attachments for Window-Shades, of which the following is a specification.

- This invention has reference to a novel attachment for window-shades which is secured to the window-frame and adapted to push or shift the upper portion of an unrolled shade out of its normal position when pulled down so that the air may pass into and out of the room both sidewise and at the top. In this way a direct draft relative to persons in the room is prevented.

The present. invention pertains to improvements in attachments for windowshades of that type covered by my U. S. Patent No. 1,098,730, datedJune 2, 1914. While in the drawing of said patent an attachment for window-shades is described which simply allows air to pass sidewise into and out of the room, the present invention has for its purpose to produce an attachment which, when operated, leaves, the top space near the window-frame completely open, so that airpasses into and out of the room at the top'and partially at the sides.

This has been primarily attained by mounting the window-shade directly in a supporting frame pivotally mounted on the window-frame and adapted to be operated so that the shade is near the window-frame in a normal position and may be operated so as to bring said shade somewhat away from the window-frame leaving the top fully open and permitting also 'of the ingress and egress of air at the sides. Both devices, the one of the co-pending application and the one forming essentially the subject matter of the present application, may be combined so as to render it possible to operate each device alone so that either effect may be obtained, that is, ingress and egress of air may be had, in one instance from the top and sides, and in the other instance from the sides only.

The invention is illustrated in the accompanying drawing in which:

Figure 1 represents in elevation a window-frame with the present attachment applied thereto embodying in desirable form the present improvements. Fig. 2' illustrates in partial side section-an attachment Specification of Letters Patent.

after having been operated. Fig. 3 shows in perspective detail view an extensible shade frame. Fig. 4 illustrates a modified form of the device permitting of the ingress and egress of air either from the sides alone or from the sides and top.

Similar characters of reference denote like parts in all the figures.

In the drawings, a represents the windowframe and Z) the window-shade. for the attachment comprises an extensible horizontal bar or rod 0 having integral side portions 0, 0 one at each side at right angles thereto. The lower end portions of the side branches serve for pivotally securing The frame the attachment to the window-frame by means of the screws or pivots 03, The window-shade b is mounted in the top end portions of the side branches 0 c of the bar or rod 0 so that it moves with the same when the attachment is operated. In this way an open space is created at the top of the window between the window-frame and the attachment when the latter is pulled in a downward direction because the shade is mounted within the attachment and, there fore, pulled away from the window-frame, as shown in Fig. 2. In order to mount the shade frame in a substantial manner the side branch (1 with its pivot 03 is mounted on a The shade frame In Figs. 1 and? of the drawing the side branch 0 of the shade frame is provided with a metal hook g, and a metal rod h having a corresponding hook is movably connected thereto by means of a screw 5. The

rod h is slightly curved at the top, as shown in Fig. 1, so as to bring it somewhat away from the shade frame for the purpose of rendering it possible to allow its lower portion-to slide in a support j secured to the lower portion of the window frame. This support is provided with a set screw 70 whereby the rod h is secured in any desired position. At the bottom of the rod it there is a knurled head Z to facilitate its up and downward movement. The shade b is pulled downwardly by means ofa cord m in the usual manner. The cord has one or more rings n to secure it on a hook located cena frame are adjustable as to position and any I ment for window-shades is so simple that desired size of top opening may be obtained by means of the shifting rod 11. and. its securing 'setscrew lo.

The described construction of the attachthe cost of roduction is relatively low and liability to erangement and repairs greatly reduced. i For the purpose of rendering the attachment applicable for windows and shades of various width the top bar a of the shade frame is extensible, as shown in Figsl and 3. This bar is cut in the center and the severed portions areadapted to slide in a groovedsupport p. When adjusted as desired the two portions of the top bar a are secured by means of screws 9. -A modified form of. the device is illustrated in Fig. 4 in which theattachment is v provided with ashade mounted within the which one is shown in Fig. 4. These side branches 1- are movably mounted on the piv- *o'tsjd, d andthe angular baris somewhat smaller than the shade frame. 40

Assuming nowthat it is desired to have side openings only .for the ingress and egress of the air then the shade frame with the shade?) is leftin its uppermost position and the shade is pulled down, as shown in Fig. 4. The angular bar 1' has centrally a small ring 1* to whicha cord .9 is attached. When this cord 8 is pulled down and secured the bar 1' .with its rectangular side branches 1' as back when released.

I claim as my invention: In an attachment for roller window shades comprislng means to create air passages at the sides and top'or at the sides only of the shade when unrolled, a frame comprising an extensible horizontal bar, the two ends of which are bent at substantially a right angle to said bar, said bent ends being provided at points near said bar with-fixtures for holding a shade roller, means for pivotally attaching said frame to the sides of the window casing, and means for raising and lowering said frame; a second frame likewise consisting of an extensible hor zontal bar provided with end portions bent at right angles to said bar, and means for raising and lowering said second frame;

stops for limiting the movements of both said first and second frames, when the said frames assume a substantially horizontal position, the'length of the side portions of said second frame eing sufficiently less than the length of the corresponding portions of said first frame as to provide space for said curtain roller between the two bars of said two frames, both said frames being mounted upon one and the same pair of pivots, substantially as described.
