Description
To all whom it muy concer-nr v f i jBeitknown that I, WILLIAM I. Yarns, otElmira, -in the county of Ghemung and State of New York, t `have invented a new and 4ns'efu mprovement in Ourtaili'dixtures;` andI do hereby`f". .declare`tl1at1he following is a full, clear, and exact description thereof, l `which will enable othersgskilled in'- the -art to make `and usethe same, reference being hadto the accomplnying drawing forming part of this speciication.`
Thisinventionrelatesto anew andusefulimprovei ment `in curtain-fixtures, having particular reference to the mode of revolving `the curtain-roller, and coni sists in so applying the powerto the roller thata vat .in each ijevolutiom'the curtain will balance the spring, as wlll be hereinafter more-fnlly described. Theaccompanying drawing represents a front view Vwhich it is revolved.` y Similar letters of reference parts. t-
i a is the roller, which is niade `to revolve on pivots for bearings at its ends, by means of clock-work, c, at- `tacbed to thewindmvasing. y
.Bisthecurtaia p This clock-,workconsistsof a wheel, d, and .pinion c, andaeoil-spring, f. l i t One end of the spring is attached to the cross-bar g, and the other to thearbor of the wheel d.
` indicate corresponding f roller and-winds up the spring, and the recoil of the spring revolves the roller inan opposite direction, and
winds up the curtain.
riablepurchase isobtained, and so that, at one point i, t of mydmprovedcuitaiii-ixtnre,showing the roller` with the curtainlthereon, andlthemechanism by The act'of drawing down the curtain .revolves the' "waited" gelistet @met elimine. i i i v4WILL;.an ivarnsyor riparian,Z NEW'YORK. d

IMPROVEMENT IM CURTAN'HXTURESf t Theishedule referred toin these Leticia P'tet 'and inkug'p'c of the s'anie. l
h isv an arm on the end of the `curtain-roller pivot.
i is a crank on the end of the pinion-arbor.
The-wrist of this crank, j, is always in contact with the arm, Aand traverses the arm nearly Afrom end toend at 'every revolution. v
Whenthe wrist j is nea-r the end of the arm, as seen inthe drawing, ita-has a long purchase, and e25- erts its greatest force" upon the roller, but when 1t l bears upon the arm at a point near the axis or pivot, j (as vwhen its position on the arm is reversed,)V it exerts lint a slight force upon the roller, and the curtain will balance the spring. A
It will' tiIlls be seen that, at' one point in each revolution itli'e roller, the curtain may remain stationl ary. A slight pull upon the curtain when it is thus held stationary will alter the position of the wrist on d the arm, giving it more lever purchase, `and wind up the curtain, ,morev or less, as may be"`desired. 'llieA momentum of the moving'part's carries the roller past necessary to draw down suiicientiy hard to counteract the force ofthe spring.
'Having thusdescribed my invention,
I claim as new and desire to secure by. Letters Patentt t In combination with a curtain-roller, the clock-work c, the arm h, and the crank t, arranged and operating substantially as and for-the purposes described. Y
