JOHN Hf WILHELM, or oH'LoAco, `1LLINo1s.

Letters Patent No. 109,087, daad-November s, 187e The Schedule referred to in these LettersA Patent and making part of the same.

To all whom. it may concern Be it known am I, JOHN H. wltnnmf, -of cin cago, m the county of Cook and State h of Illinois, have invented an Improved Curtain-Fixture and I dohereby declare that the following is. a full and exact descriptionl thereof, which will' enable those skilled in the art to make and use the same, reference being had to the accompanying drawing and letters marked thereon making a part ot' this specification,'in which Figure l is an elevation ol' a u'hnlow-l'ranie with my curtainxture attached.

Figure 2, a longitudinal central section of the roller and brackets, with detailed views.

Figure 3, an elevation of a wilnlow-fran|e with the bracket-s fastened to the jamb-casings.

Figure 4, a perspective view of the movable washer, against whichtho spring operates .in raising and lowering the curtain, and in holdingit in position.

Figure 5, aperspectivc view ofthe imbedded washer and tube-guide.

Figure 6 represents thc weight attached to the betteln of the curtain or shade.

Figure 7 shows the slot in the bracket for the more convenient reception ot'thejournal ofthe roller.

rlhe object of this invention is toprovidc an adjustable whnlow-curtain fixture, adapted not only to windows of diii`erent widths, but also to those of' different heights; andv Its nature consists in a device for removing the pressure of the spring that holds the Vcurtain in position, and in thc combination and arrangement oi' parts, as hereinafter more fully described.

Figs. 1 and 2 represent a wooden roller, with the journal 1t and spool-collar plate l similar to the same parts in my curtain-fixture patented July 2G, 1870.

The bracket B with the central. socket L, and the bracket E with the cord-guard J, are also similar in all respects to the same parts in my cui't-ain-xtui'e for which Letters Pat-ent have been granted bearing the above date, with the exception of the orifice K in the bracket B, and the ordinary slot S in the bracket E.

H, iig. 2, represents a metallic tube, having a slot, L', and, when made as a casting, it is more convenient to cast it in two separate pieces.

The corresponding parts W \V, when put together and inclosed within the cylindrical spiral spring l, form the tube H with the slot L.

The tube H may be made ot' any suitable metallic substance, and in two parts, or asone single tube.

J, figs. 2 and 4, represents a movable washer, with a cross-bar, N, and a hole on each side of N to admit the parts W l or prongs of the tube H.

The projections n n are designed to prevent the spring I from slipping between the tube H and the washer J. y

\Vhen the spring-I is suiiiciently'large to obviate this difficulty by means of its thickness, the projections n n' may with advantage be omitted.

l.he cord C is fastened to the cross-bar N.

K is an orifice through the central part of the socket L in bracket B, iig. 2, through which the cord G passes.

1l, iig. 5, is a single casting, answering the purpose both of a washer and tube-guide, andis inserted in the hole G bored in the large end of the roller after it has been properly adjusted to the width of the window.

P is a slot, designed to receive a bent implement or wire for the purpose of drawing out P when necessary.

lhe movable washer J, 2, 'operates against the spring I on the tube H, and against the imbedded washer and tube-guide I), lig. 5.

Q', tig. 6, represents a weight attached to the slat Q, or to the bottom of the curtain or shade.

@ne or more weights may be thus attached when necessary.

Q may be dispensed with when the weight of the curtain is itself sutlicient to cause it to unroll on removing the pressure. from the spring I by pulling the cord U. I

The cord C, with the device to which it is attached, is designed to lower the curtain when the window is so high that the curtaintwhen drawn up by means of the cord l), cannot be conveniently reached by the hand.

By pulling the cord C the curtain A may be lowered to any desired point. p

Then the curtain is so heavy as to require the spring I to be of greater strength than usual, it may be drawn up more easily by, at the same time, while pulling the cord'D also pulling the cord IG, so as to Y remove the pressure of the spring I.

,By the same process, managing both cords at once, the operating of the roller Ennay be Vmade almost or entirely noisel'css.

Having described my invention,

XVhat I claim, and desire to secure by Let-ters Pat-1 l. Y The imbedded washer and tube-guide l in combination with the movable washer J, the tube H, the cylindrical helical spring I, the cord 0,' the bracket B, oriiice K, and` roller F, when all the parts are constructed and arranged to operate as herein described, and for the purpose set forth.

il. The imbedded washer and tube-guide P in com` bination witlrthe movable washer J, the tube H, the cylindrical helical spring I, the cord (i, the bracket B,

orifice K,u roller F, spool collar-plate T, bracket E, and

cord-gua1dV,wl1en all the parts are constructed' and arranged to operate as herein described, and for the purpose seb forth.

3. The imbedded washer and tube-guide P in conibination with the movable washer J, the tube VH, the

cylindrical helical spring I, the cord C,

the bracket B, orifice K, roller F, spool collar-plate T, bracket E,

cord-guard V, and weight Q on the bottom of the fitnessesz GEORGE L. CHAPIN, E. E. GIBSON.
