SPECIFICATION forming part of Reissued Letters Patent No. 11,912, dated June 4, 1901. Original No. 660,133, dated May 12,1896. Application for reissuefiled April 15, 1901. Serial No. 56,003.

To all whom it may'c onccrm. I

Be it known that I, PLATO G. EMERY, of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Fixtures for Window Gurtains or Shades, of which the following is a specification, reference being had, to the accompanying drawings and to the letters of reference marked thereon.

My invention relates to improvements in fixtures for window curtains or shades, more especially such as are used on railway-cars, the object being to provide a cheap, simple, and efiective device whereby the curtain or shade may be raised or lowered and retained in any position,- this being done by simply raising or lowering with the hand the rod usually attached to the bottom of the curtain or shade. This object and others I attain by means of the arrangement of parts shown in the accompanying drawings, in which- Figure 1 is an elevation of the inner side of a car-window having my invention attached.

Fig. 2 is a sectional view of the lower end of the curtain on an enlarged scale, the section being taken on the line 2 2. Fig. 3 is a longitudinal section on the line 3 3'. Fig. 4 is an end view ofthe lower end of the curtain. Fig. 5 is a view of a detail; and Figs. 6 and 7 show modifications.

Similarletters of reference indicate similar parts in the respective figures.

Referring to the drawings, A represents a window-frame provided with sash in the usual manner, in front of which is hung the curtain or shade B from a spring-roller O,which turns in bearings mounted at the sides of the window-frame near the top in the ordinary manner. The spring-roller C differs from those in common use in that it is not provided with stops, the tendency therefore being to keep the shade constantly rolled up.

To the bottom of the shade B is secured a hollow rod D, lying in a horizontal position, within each end of which is a pulley E or F.

The pulleys may, however, be double, as seen in Fig. 7, or omitted altogether.

A cord, chain, or wire G, secured to the bot tom of the window-frame at one side, as at a,

extends upward to the pulley E, the said pulley being journaled in one end of the hollow rod D, over which it isv carried. Thence it passes through the hollow rod D to the opposite pulley F. Passing downwardly under this pulley it again extends upwardly on this side of the window to the topof the windowframe, where it is threaded through a loopb. From this point it runs-in ahorizontal direction behind the spring-roller O 'to a similar loop I) on the opposite side 'of the window, through it and downwardly to and under the pulley E in the hollow rodD, through which rod it again passes, crossing the part of the cord first introduced to the top of the pulley F, and thence over the said pulley and down to the bottom of the window-frame, where it is secured at a. It will be seen that by this arrangement the shade may be raised or lowered to any desired position and there retained, it being understood that the tension of. the spring-roller is insufiicie'nt to overcome the friction of the cord, but great enough to roll up the curtain as it is raised. The cord will prevent any side movement of the shade,

and by the peculiar manner of arranging it the bottomv rod of the shade will be retained at all times in a position parallel to the roller 0, .thus avoiding the irregular winding usually found in spring-rollers employed, at the present time. I do not confine myself to the use of a cord, as I may in some cases use a chain or wire therefor. I

It it well known that all flexible material will after use and wear stretch more or less. To overcome this defect, which would render the operation of my device less eifective, I provide a take-up coupling. (Shown at H, Fig. 1, and in detail in Fig.5.) As shown, it consists of two right-angled plates hh,through the horizontal members h of which the cord G passes, as seen in Fig.' 5. The vertical members of said plates are connected by a right and left threaded screw 1. -As the cord G stretches by wear the screw I,on being turned,

= having and extending across the top venient means for taking up the slack it is evident that the'same result may be obtained by detaching one of the ends of the cord where fastened below, as at a, andtightening the cord and again securing it at that point. The ends ofthe run in grooves in the sides of the windowframe, within which the cord will also lie. The spring-roller will cover thetake-up coupling, thus coucealing it from view from-the interior of the car.

have shown a flat rod D asa substitute for the hollow rod D.

rod instead of within the ends, as above described, this arrangement being cheaper and while not, however, presenting as neat an appearance as the preferred form.

It will be seen that by supporting the cord, chain, or wirebya loop at each upper corner of thewindow-frame the cord is free to be drawn through the loops when it is desired to tighten it. Thus by unfastening one of the ends of the cord at a lower corner of the window-frame and drawing onthe cord it will slip through both loops and under and over the pulleys until the desired tension is obtained, when .it may be again secured at the.

point from which it was detached. It is evident that this simple and convenient mode of tightening the cord is not available if the upper-corner-supports of the cord are not in the form of will allow of the slip mentioned.

Having thus described my iuvention, I-
