SPECIFICATION forming part of Letters Patent No. 725,950, dated April 21, 1903.

Original application filed July 13. 1901, Serial No. 68,216. Divided and this application 'filed April 16, 1902. Serial No. 103,203. (No model.)

To all whom it may concern:

Be it known that I, HENRY H. FORSYTH, a citizen of the' United States, residing at Ohicago, in the county of Cook and State of Illi- 5 nois, have invented certain new and useful Improvements in Curtain-Fixtures, of which the following is a specification.

This application is a division of my application, Serial No. 68,216, filed in the United :0 Stat-es Patent Office July 13, 1901, and the improvement hereinafter described isgenerically claimed in said prior application.

The improvement herein described relates to a particular form of curtainfixture or holding device for spring-actuated curtains, which, generically considered, comprises a holding device which is brought into action or rendered operative by the pull of the spring of the curtain-roller and which is automatically released as soon as the pull of the curtainroller spring is overcome.

In the accompanying drawings, Figure 1 is a side elevation, partly broken away and partly in section, showing one corner of a window shade or curtain, a'portion of the shade-stick and holding device, and showing a friction-shoe in holding engagementwith; the frame ofthe window. Fig. 2 is also an' elevation showing the released position of the holding-shoe, and Fig. 3 is a front elevation or edge view.

In the drawings, 4 represents an ordinary spring-actuated curtain-roll.

5 represents the curtain, and 6 the usual curtain-stick.

7 represents a sliding rod mounted within the curtain-stick and carrying a head 8, whose shank 1O slides in the stick, and 9 is a coil-- spring exerting an outward thrust or pressure upon the shank 10,.carried by the head. The head itself is in the form of a hollow metal box and carries at its extremities and in its open side the antifriction-rollers 11 12. These rollers not only serve to guide the fixture groove, but reduce to some extent the fric tion which would tend to retard its movement or. hold it in a stationary position, and they also aid the fixture to right itself in case the curtain-stick is canted or tilted from the smoothly in its travel up and down in the.

horizontal position. iThe holding device proper consists of an elongated shoe 13, which is pivotally connected to the head and within the hollow thereof by means of the swinging links 14, these links being pivoted, respectively, to the shoes and to the hollow head. The swinging movement of the links is limited by the stop-pins' 15 16, and the shoe projects to such a'distance beyond the open ing of the head and the latter is held in such relation to the window-frame, which is indicated at 17, that the upward pull of the spring of the curtain-roller causes the face of the shoe to make such frictional contact withthe bottom of the groove of the window-frame as to arrest the upward movement of the fixture, overcoming the pull of the spring. The relation of the parts is such that the shoe automatically engages the window-frame and prevents upward movement of the cur- 7o tain except when such force is applied as to overcome the friction, and this force may be applied directly to the bottom of the shade by grasping the lower edge of the stick and forcingit up, or the heads may be slightly 7'5 withdrawn by retracting the rod 7 against the thrust of the springs 9 by means of the usual pendants or pinch-handles 18. When the curtain is pulled down, the shoes automatically release themselves, the links swinging 8o upwardly and carrying the shoes inwardly or away from the face of .the frame; but immediately the curtain is released the spring of the shade-roller draws the shoe into holding contact with'the frame, said shoe being at all times in position to instantly engage upon the cessation of the downward movement of the curtain. The holding contact of the shoes will serve to move the heads slightly away from the face of the frame, thus carry- 0' ing the rollers 11 12 out of contact therewith, as shown in Fig. 1.

I claim 1. In a curtain-fixture, the combination with a spring-actuated curtain or shade, of a curtain-stick carried thereby, heads carried by said curtain-stick, and elongated frictionshoes pivotally connected to said heads by means of swinging links, substantially as described. ICO

with a spring-actuated curtain or shade haw ing a curtain-stick at its free end spring-actuated rods slidably mounted in said stick, heads carried by said rods, elongated frictionshoes, pivoted links connecting said shoes with said heads and means for limiting the swinging movement of said links; substantially as described.
