i Latas Patent No. 103,167, dated May 17, 1870; Mezzana May 10,1870;

IMfPRovnn cnnmmrrxrnlnnj f `The Schedule referred toin these Letters Patent and making part oi the same l I, GEORGE PLINY FULLER, of Humphrey, in the county of Gattaraugus and State of New York, have invented certain Improvements in Curtain-Iiixtures, of which the following .is a specifieation The nature of `my invention consists, in the first place, ineXtenson-brackets, made in two or more by means of grooves on the face of one piece, at the edges thereof, between Which the adjoining piece is caused to slide, to adjust l it; or the grooves are dispensedwith, and the pieces are held together when adjusted, by means of rivets, or in any other convenient manner, as hereinafter described. l I i llhe 'object attained by the construction of the brackets in separate pieces is, the adjustment of them tovariable thicknesses ot' window-sash; and to difi'erent widths ofthe window-jainbs, and their accommodation to rollers when hung outside ot' the windowframes. i

The invention, in thesecon'd place, consists in preserving the height ot the lower endof the curtain, by

` means of a cross-cord and` pulley on one 4end of the curtain-roller, so asto wind the curtain as the upper sash is lowered, and to unwind itwhen the same is raised. l i

`.lo enable others skilled in the art to which my im-v provement appertains to apply the same to practice,

I will now fully explain it.

In the accompanying drawings, which .make a part of` this specification- Figure 1 is a front elevation of a window with the improvements attached. i a

Figure 2 is a vertical section at the line a b of tig.1; Figure 3 is an isometrical view of one ofthe extensio"n brackets D made in two adjustable pieces, to accommodate it to any depth of the window-jamb.

Figure'fl is a like ,viewwof a' bracket, D', composed of three pieces in accommodationto the curtain`-rollcr,' when the latter is hung in front of the window.

Figure 5 is a xiewbf the piece bv-of the brackets D.: v. Y i

Figure` a View` of the piece b, showing a rhodified mod ctin th of the` bracket to gether.

, Figure coil-spring detached froni Like letters A is the window-tram l B is the lower, and I C the upper sash.

D D are extension-brackets which sustain the roller E, on which the curtain F is hung, the feet a of' the rbrackets being fastened by means oi screws to the when the curtain F is hung inside of the frame, so as to be adjustable to any thickness of the window-sash. 4

One of the brackets is represented in detail in g.,3.

The said pieces a b being held in their adjusted position by means of' the' grooves c c on the face of the piece b, between which the piece b' is placed, the turned over edges (l d of the piece b being hammered down to hold the piece I1 securely, to keep it ,from slipping endwise.

The piece b is shown in detail in hg. 5.

When the curtain F is to be hung in `front of' the window,Iconstruct brackets D of three pieces. One of the brackets is represented in fig. 4. This bracket is made like the bracket shown in fig. 3, with the exception of the part e, being left o" thepiecc b, and thev piece 7) being connected with the elbow c of the or the fastening may. be effected in any other conven# ient manner.

'Iusually make the brackets of sheet-iron or brass.

butdo not conne myself to this plan.

On one end of the curtain-roller E there is a sheave, G, which receives the cross-cord H, one end of' which is suspended for manipulation, and fastened tothe `window-jamb; the other end is passed through the staple f in the head of the frame A, and wound around the pulley I, ou 'one end of the sleeve J. Said sleeve turns on the short shaft K which projects inward from the window-frame A.

There is a case, L, which contains a coil-spring, M,

Lto which one end ot Vthe spring is attached, the other end being fastened to the sleeve J.

' v The spring M, case L, and sleeve J are represented in connection, inv iig. 7. 1

The lower end ot' the curtain F is adjusted to any desired height, by the winding, or unwinding of the cord H on the pulley I, which is effectedv by pulling, or slacking the lower end of the cord. When the cord v is pulled, said pulley is turned in the direction of the arrow, and the curtain is lowered at its lower end, andnwhe'n the cord is slackened, the force ot' the colspringM, connected with the sleeve J of the pulley as above described, turns the pulley I in the opposite direction, and winds up tially, as may bedesired.

When the height ot`thc lower end of thepcurtain is only to be varie-d, the lower end 0i` the cord is secured, to resist the action of the spring M; but, when the curtain is to .be wound clear up, the spring is allowed sufficient play to accomplish it.

the curtain wholly, or parmorepieces b b' b", and connected together by means of grooves c or rivets, as hereinbefore described.

2. The combination of the roller E, sheave G, cord H, staple f, pulley I and shaft K, with the curtain F, and window-fiume A; the said cord being attached D' formed of two or at one end to the pulley I, and lthe other end sns-l pended, or fastened to said frameI A, and the shaft K provided with a spring, M all constructed and arranged for joint operation, as above described.

In testimony that the 'above is my invention, I

have hereunto set my hand and axed my seal, this.

12th day of Oct-ober, 1869.
