SPECIFICATION forming part of Letters Patent No. 472,832, dated April 12, 1892.

Application tiled May 29, 1891. Serial No.394,601. (No model.)

T0 all whom t may concern.-

Be it known that I, HUGH M. SWEENEY, a citizen of the United States, and a resident of Boston, in the countyof Suffolk and State of -Massachusetts, have invented new and use- &c., although it may to advantage be used on other window-shades, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein- Figure l represents a front elevation of va window-curtain provided with my invention. Fig. 2 represents a cross-section on the line X X in Fig. l, shown as enlarged. Fig. 3 represcnts a vertical section of a modication of the invention, and Fig. 4 represents a crosssection on the lineYY shownin Fig. 3. Fig. ,5 represents a vertical section of another modification, and Fig. 6 represents a crosssection on the line Z Z shown in Fig. 5.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings. l

The object of my invention is to provide a window-curtain with a friction device for retaining it in any desired position, so as to prevent it from flying up in case a spring-fixture is used and to prevent it from sagging down if used in connection with otherkinds of curtain-rollers or curtain-holding devices.

vIn Fig. l, A represents a curtain-roller of any well-known construction, such as a springfixture or otheikind, as may be desired.

B is the shade or curtain, as usual, having a bar b attached to its lower portion.

C C are the vertical guide-posts,which may be made of wood with iiat inner surfaces, as shown in Figs. 1 and 2,-or may be made as metal rods or tubes, as shown in Figs. 3, 4, 5, and 6. To each end of the rod b is detachably secured by screws a metallic box or chambered plate D, containing a spring pressed friction-block D', which is guided and supported by the side walls of the box and held with a yielding pressure against the post or rod C by means of a spring D, preferably interposed between said box and frictionblock, as shown. To the upper and lower ends of the boxes D D are journaled the antifriction guide-rollers E E, that serve for the purpose of preventing the bar b and its friction-blocks from kinking or binding against the posts or rods C C in case the said bar b 6o should be raised or lowered while in an inclined position, said rollers thus serving to properly guide the curtain while it is being. operated. The boxes D and their frictionblocks D may be guided relative to the posts or rods C in any suitable manner, andl have shown for this purpose in Figs. l and 2 vertical rabbeted side pieces C C. In Figs. 3 and 4 the friction-blocks are shown concave,

so as to it the rods C, and in Figs. 5 and 6 7oV the said blocks are likewise shown concave, and additional outside rollers E E are shown for more effectually guiding the boxes -D D on the rods or tubes C C. By detachably securing the curtain rod or bar Z9 to the metal- 75 lic boxes D it is possible to remove the curtain and its rod or bar while leaving the boxes in position on the guide-posts C, so that the boxes,

with their friction-blocks, will always be in' correct position on Ythe guide-posts, even 8c though the curtain and its rod or bar b are removed.

Either of the above-mentioned guide devices maybe used to equal advantage without departing from the essence of my invention. 8 5

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and.claiml. The combination, with a shade -roller,

vertical guide-posts, and a shade having a 9c shade-bar at its lower edge, of a box secured to each end of the shade-bar and provided with anti-friction rollers bearing against the guide-posts, a friction-block located inside of each box and guided by the side walls thereof, 9 5

and a spring acting toY press each frictionblockv against a guide-post, substantially as described. l

2. The combination, with a shade-roller,

vertical guide-posts, and a shade having a roo.

shade-bar at its lower edge, of a metallic box secured to each end of the shade-bar and guided in engagement with the guide-posts, a friction-block located inside of each box and box, and a spring interposed between each 'box and its friotion-blockcto press the latter I 5 against a guide-post, substantially as described.

In testimony whereof I have signed my name to this specification', in the presence of two subscribing witnesses, `on this 28th day 2o of May, A. D. 1891.

HUGH M. SWEENEY.
