GEORGE H. DAVIS, OF PORTLAND, MAINE, ASSIGNOR TO THE CURTAIN SUPPLY COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.
To all whom it may concern:
Be it known that I, GE RGE H. DAVIS, a citizen of the United States of America, and a resident of Portland, Cumberland county, State of Maine, have invented certain new and useful Improvements in Window-Shade- Holding Devices, of which the following is a specification.
This invention relates to improvements in curtain or shade holding fixtures, and has for its object the provision of a device designed primarily for use in connection with a spring actuated roller and adapted to engage the runway of a window frame to. hold a shade in desired positions of adjustment, said device including an elongated head, a friction surface or surfaces carried thereby for engagement with the base of said runway, and antifriction surfaces arranged to contact with the side or confining walls of the groove, the purpose of these anti-friction surfaces being to facilitate a free and easy manipulation of the fixture by overcoming the objections to existing devices wherein an elongated carrying head or shoe for the friction surface, presenting relatively extensive side surfaces, enters the guide-way or groove in the frame or casing, and in its vertical sliding movement under the pressure of the hand is ofttimes forced into frictional contact with said side or confining walls of the groove thereby correspondingly retarding the shifting of the head in said groove, a fixture of this last mentioned type being illustrated in the Forsyth patent No. 559,446.
Several convenient embodiments of the invention disclosing the underlying principle of the same are illustrated in the accompanying drawings, and upon an inspection thereof in connection with the detailed description hereinafter given, it will be apparent that the advantages inherent in an elongated head or shoe are preserved in addition to the accomplishment of the ends desired to be attained by the present improvements. These particular embodiments also possess novel de tails of construction and arrangement as will be presently defined.
1n the drawings, Figure 1, is a front elevation of a portion of a window frame or casing showing the usual constantly acting spring roller mounted at the upper portion thereof, the curtain or shade secured thereto, and one Specification of Letters Patent.

form of holding fixture carried by the bottom of the curtain, parts being broken away to disclose the interior portions of said fixture; Fig. 2, is an end elevation of the fixture just referred to, the side or confining walls of the guide-way or groove being shown in section; Fig. 3, is an elevational-sectional view of one end of another form of fixture; and Fig. 4, is an end view of the same.
Referring more specifically to the drawings in the respective series of views of Which corresponding reference characters refer to the same parts, and .now with reference more particularly to Figs. 1 and 2, A designates the frame or casing of an ordinary window, and B inwardly facing guide-Ways or grooves formed therein. C is a constantly acting spring roller common in this art, mounted at the upper end of the frame A D the. curtain or shade secured to said roller adapted to wind upon or be unwound from the same according to the adjustment of the shade de sired, and E is a tube or housing carried by the bottom of the shade and constituting a part of the holding fixture designed to resist the winding of the shade upon the spring roller whereby to maintain the former in adjusted positions. Secured to the ends of the tube E are hollow heads F having a threaded engagement f to permit of the proper adjustment of the same relative to the bases 1) of the grooves B. Adapted to be reciprocated Within the hollow heads F and the tube E are oppositely disposed rods Gr each branched at its outer end to provide vertical arms g, these arms in turn being off-set to provide extensions g arranged parallel with the longitudinal axis of the rod, as clearly indicated in Fig. 1. Upon the extremities of the extensions g are friction shoes or surfaces H designed to bear against the base 6 of the guide groove B, said shoes being of any desired substance such as rubber or metal, preferably the latter, and rounded as shown to permit the fixture to rock thereon to a limited extent when the same is canted soas to facilitate the self-righting of the fixture. Any suitable instrumentalities may be afforded for creating the desired holding pressure between the surface of the shoes and the base of the groove, for instance a spring I carried upon the rod G, at one end engaging a projection ion the rod and at its opposite end bearing against a fixed abutment i on the interior of the tube E. The tendency of the spring is of course to normally thrust the shoes H into contact with the base of the grooves. Although the fixture may be employed without the provision of retracting means, I have shown the inner ends of the rods G as formed with pendants or pinch handles J depending through a slot j in the bottom of the tube E.
Surrounding the friction shoes H I provide anti-friction devices K, the same being in the nature of hollow rollers flanged at one end as at k and carrying suitable bearings 75 sleeved for rotary movement u on the extensions g of the arms g, said r0 lers being of a size to engage and run along either of the side or confining walls I) of the groove B should the same be thrown into contact therewith by the lateral movement of the fixture under the pressure of the hand in ad justing the shoe, so as to prevent any frictional resistance to the raising and lowering of the fixture within the guide ways as is obvious.
In Figs. 3 and 4,15 represents a stick corresponding to the tube E in the first two figures, said stick being bored at its ends for the reception of short rods G carried by the heads F, said rods being backed by springs I and restricted in their movements by pins L working in short slots Z in the stick, said slots opening to the bores at the ends of the stick. At the ends of the head F are stub p/Iintles m carrying friction shoes or surfaces adapted to engage the base n of the guideway or groove N, and upon these pintles and intermediate the friction shoes or surfaces M and the head F are rollers K adapted to engage the side or confining walls n of the groove N.
Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is 1. In a curtain holding device, the combination with the curtain stick and a spring roller curtain, of a rod or spindle longitudinally movable in said curtain stick, a friction tip on the outer end of said rod or spindle, a spring for forcing the same outward, means for withdrawing the same, and a rotatable sleeve surrounding said tip and journaled on the end of said rod to form an anti-friction roll.
2. A curtain holding device having an elongated head, separate friction devices, instrumentalities for mounting the same one adjacent to each end of the head for engagement with the base of a guide groove, and for releasing the friction devices, and an antifriction device connected to move with the head and contact with the side or confining wall of said groove, when said friction devices are released.
3. A curtain holding device. having an elongated head, separate friction shoes, means for mounting the same to move with the head one adjacent to each end of the head for engagement with the base of a guide groove, and anti-friction rollers mounted upon said mentioned means adapted to contact with the side or confining walls of said guide groove.
