' Leim Patent No. 106,211', met August c, 1870.

IMPROVED CURTAIN-FIXTURE.

.The` Schedulel referred to in these Letters Patent and making part ofthe same.

.l I, `FBANKIJIN ROT, of Hartford, in the county of Hartford and State "of Connecticut, have invented certain `Improvement-s `in Ourtain-Fixtures, of which the following isa specification.

` lilatmjeand Objects ofthe Invention'.

Qne part of my invention 'relates tothe manner of Aattaching the metal spools? or pulleys to the ends of the roller-usually fastened at `the Vtop of the window,

and theV object is to so fasten theretovcertai'n collars or flanges thatthe proper adjustment `of another roller, which depends by cords from said collat, may readily be made.

` l Another part of my invention relatesto an apparatus whereby a secondary roller, bearing the curtain, and ,which may be made to rise and tall at will, thus allowing the curtain to be let vdown at the top, as well as raised at the bottoin,lnay also be made,

at "any pointfof dependence, to roll v the curtain up fro'mthe bottom;

My invention has but these twopartsf L f :Description 'of 'the `Accom@omging Drawing. y

Fgurel'is a front `view of a window with my in` vcntionattachedr' Figure-2 is a detached sectional vi'c'wo'f the pulley l or spoolattached to thcfendjof the movable orfsecondary roller.

Figure?) is adetached sectional view,1showing the method ot'attaching the spools? or pulleys to the endslofthe'tixedrollcr.

General Descryiticu. A is' the frame ofthe window. Bis the fixed roller turninginfthe bearings .a a.

To one @end of the roller B is attached Va metal spool or pulley, shown in sectionin iig. 3,'compose'dof"two pieces, b, with a sorewattached, screwing `into the end of the roll,*and the collar or flange c, fit- -ting on over the scre\v,.whicl1`is fastened'on tight-ly by driving" the screwinto the wood.'

f `{lhisdevicfe has two grooves for cords, one at dand 'one at e."

In the groove d runs an endless -cord, x, running also around a pulley,.;f,'at the bottornof the window,

which is fastened to the frame by a spring, so as to volve the `roller B one way'or the otherfas the cord is pulled.

flange or collar c isfastened on precisely 'as is the collar c.

In the 'grooves c and'c' run thecords g g.

These cords are fastened by running them through ble roller 0,.;which must, of necessity, be kept 1evel.'

g g should Acom- 1 Hence itis necessary that the cords mcnce to wind at just the same time. V

yThis is eiiected by having the collars c andv c' lbse from the screws which fasten them to the roller, so that the knots can be placed exactly in the right places to effect such adjustment.

' rTo the lower end of the cords g g are attached banging bearings o n, in which the ends of the roller C turn freely. l

The curtain D is attached to thismovable roller C, and it will be readily understood that, as the roller B is made `to revolve by means of the cord :1s-, the roller O will be moved up or'down, and the curtain let down or raised at-the top accordingly. Around the loosefpulley l1', and down around the pulley j","runs the, endless cord x', kept taut in the samelmanner as thetcord x.`

Thiscord takes-a single turn around the pulley i, attached to thefroller G, so as to turn the 4roller when the 'cord is pulled up or down.

It is thus obvious that, no matter -at what point theroller O is suspended, the curtain can ybe rolled `u p or let down at the bottom, by means. of the cordrc',"witho ut at all al'ecting the status ofthe roller 0.

`Not only this, but, when the roller V(l is moved up Vor down Aby means of the cord x, the oord x will causeittorevolve with just the right direction and ,motion to roll or unrollthe curtain at the top, so that the status of the bottomof the curtain will not be alected.

, By. this arrangement the curtain ycan be rolled .up

or down .from "the -bottom vor the top, or from any point in the line of suspension-af most convenient arrangement.

The groove in the periphery of the'pulleyt is shown' in iiig.f2,' and its shape makes it certain that the-cord will not slip on the-pulley. l

Many of the parts not claimed herein are claimed' in former applications of mine, but, witlrrespect to.

the purposesof this application, all those parts are old which are not specifically claimed herein. l

IV expressly disclaim the use of the cord @when ar rangedjas described, and applied to the' rolling of a i fixed curtain-roll. It is only when applied to :t roll 2. Thecombinettionv of the parts mentioned in the made movable in manner and form, as is the roller C, preceding clause with the movable roll C, the pulley that I claim an invention. c', cord and loose pulley b', constructed substan- Ol tially as described, for tbe purposes set forth.

aum Dated November29, 1869.

I claim as my invention- 1. `The combination of the fixed roll B, the collar- Witnesses: c, and the pulley b, constructed .substantially as de W. EDGAR SIMONDS, scribed, for the purposes set forth'. THOMAS TIERNAN.
