COLLAPSIBLE. BLIND FOR RCHED WINDOW/S.

SPECIFICATION forming part of Letters Patent No. 602,967, dated April 26, 1898.

Application filed August 5, 1397.

To all whom t may concern.:

Be it known thaiL I, GEORGE WELLS, architect, of the city of Montreal, in the county of Hochelaga, in the Province of Quebec, Canada, have invented certain new and useful lmprovements in Collapsible Blinds for Arched Windows, of which the following is a specilication.

My invention relates to improvements in collapsible blinds suitable for circular or arched windows,more particularly those forniing the upper parts of large arched windows in public buildings, the rectangular lower parts of which are suitably shaded by ordinary Venetian blinds; and the object of the invention is to devise a form of blind or blinds which will harmonize with the Venetian blinds in the lower portion of the windows and be capable of an equally ready adjustment; and my invention consists, substantially, in forming two fan-shaped collapsible blinds the slats of which are suitably pivoted near the center of thevcircle forming the arch and are suitably connected near their outer ends by a flexible band, so as to allow them to open to a limited extent, the slats farthest from the window being guided inwardly toward the window by a suitable guiderod as they are being raised, theparts being otherwise arranged as hereinafter more particularly explained, and shown in the drawings hereunto attached.

Figure l is a perspective interior view of an arched window having a collapsible' blind made in accordance with my invention attached thereto and the lower rectangular part of the window partly broken away, showing suitable means for operatin g the blind. Fig. 2 is a central vertical crosssectional perspective view of left-hand portion of arched window, showing blind raised. Fig. 23 is an enlarged detail view of outer lower portion of slats and attachments as shown in Fig. 2. Fig. 3 is a central vertical cross-sectional perspective View of right-hand portion of arched window, showing blind lowered. Fig. El is an enlarged cross-section of slats in Fig. 3 near outer end thereof.

In the drawings like letters of reference indicate corresponding parts in each ligure.

A is a fan-shaped blind, of which two are preferably used, one for the right and one semi no. 647,249. da man.)

for the left hand portions of the arched window. The blind A is composed of a plurality of thinV slats a, one end of each being pivoted on the bolt B, which is fixed to the casing of the arched window near its eenterand projects at right angles therefrom. The opposite ends of the slats are loosely connected together by flexible bands C, which are preferably arranged as a continuous band constructed in the following manner:

The lower end of the band C is firmly attached to the lower casing of the arched window at c and is brought up over nearest slat ct and down the other side of the slat, where it is attached to it by tacks C' or other suitable means, then around the lower edge, and up again, forming altogethera complete loop around the slat. The band C continues upwardly and around the next slat in an exactly similar manner, and is fastened at the back, leaving just enough slack to allow the end of the slat to be raised almost as high as the top of the preceding slat. Thus the band C continues throughout the free ends of the several slats.

To the last slat is attached the raising-cord D, which passes over a grooved wheel E, suitably supported in the bracket E', attached to the upper easement of the window' slightly to the opposite side of the center from the blind to which it is attached. The loose end of the cord falls down the center of the window, where it may be attached to a cleat or otherwise suitably held when the blind is raised.

F is a curved guide-rod fastened at each end to the outer ends of brackets G, attached to the bottom easement near each side and standing out atright angles thereto. These brackets form rests for the slats when down.

The guide-rod F follows the curve of the arch slightly inside the ends of the slats ct, but continually approaches the window toward the top, where it is held by the bracket H.

By means of the guide-rod F the first slat d, as it is raised by the cord B, dragging the rest of the slats one after the other after it, is gradually forced inwardly toward the window, thus giving a snug lit when raised.

It will be noticed that either blind may be raised independently of the other and may be adjusted to any intermediate height. The slats are made sufficiently heavy that when IOS .the cord D is let go the blind will naturally fall to the position shown in Fig. 3. The rst slat is shown in full lines in the act of being raised in Fig. 3a and in dotted lines in Figs. l and 3.

I show the blinds and all their attachments fixed to the easement of the arched Window, which may be opened for ventilation by being horizontally swung on a central pivot or other- Wise, carrying the blind with it. The blind and attachments might, however, equally Well be attached to the transom and frame, space being left when the blind is down for the Window to swing clear.

vWhat I claim as my invention isl. In a blind for arched Windows and the like, in combination a series of slats pivotally held in fan shape on a bolt substantially central to the arc of the arch and having their outer edges following such arc When open, a continuous band secured to the casing and looped successively around and attached to each slat 4and means for spreading the slats at their outer end as and for the purpose specified.

2. In a blind for arched Windows and the like, in combination a series of slats pivotally held in fan shape on a bolt substantially central to the arc of the arch and having their outer edges following such arc when open, a continuous band secured to the casing and looped successively around and attached vto each slat and a cord attached to an end slat and passing over a suitable pulley as and for the purpose specied.
