IMPROVED' CURTfN-PIXIURE.

The Schedule referred to in these Letters P atent and making part or' the same I nme- I, ALBERT E. Tiuri, of the city of Springfield, in

the county of Clark and State of Ohio, have invented certain Improvements in Curtain-Fixtures, of which the following is :a Aspecification.

4My invention Vconsists in a combination of rollers, cords, pinions, and ratchet-plates, in the construction of a useifnl and convenientdevice for raising and lowthe invention being to not only raise and lower the curtain upon the top roller, hutalso to lower the roller and curtain together, or raise them to any desired point, andretain them in place, for the purpose ot'admitting any required amountof light through the window, either below or above.

The roller upon which the curtain-is wound is hollow, turning looscly'ilpon a shaft of wood, which extends through it. Upon the outer ends of this shaft are pinions, gearing into ratchet-plates fastened to the casing on eaclr'fside of the window, and extending from the top down to middle, or lower. if desired. These "'latchet-platcs are formedso that the ends ofthe pinion-shaftare prevented from slipping out.

An endless cord extends over fixed pulleys at the top ends of the ratchet-plates, and is wrapped one or more times around the ends ofthe roller, inside ot' the pinions, passing down the sideslof the. casing, around the usual tightening-pulleys or studs fixed to the lower part ofthe window.

The cord on one end of the roller is wrapped around the huh of the pinion, and, when operated, rolls the roller and curtain together, up or down, while the cord upon the other end is wrapped around a sleeve attached to the outside roller, and titting loosely over the 'hnb of the pinion on that end. When this cord is. operated, the roller4 simply winds upor unwinds the curtain, at whatever point ou the ratchetplates the roller may be.

The pinions `more together iu raising the roller or loVeringit, keeping it at all times parallel with the tod-and bott-om ofthe window.

.-'lhe roller is held in position by the tension of the cords and the meshing of the pinion-teeth into the ratchet-plates, together, the two exerting a sufficient pressure upon the roller to hold its weight, with the curtain, at any desired height.

The ratchet-plat-es, upon Vwhich the pinions work, are constructed oi' thin .metal strips, having that edge upon which the teeth are cut bent outward with a lcurve or angle, and again inward, suliiciently to bring shaft, and to prevent the roller from heing thrown out by any sudden shock. At their lower ends a spring stop prevents the roller from falling out of the ratchetplates.

Figure 1 is a front elevation of a window to which my improved curtain-fixtures arel applied.

. Figure 2 is a sectional view of the saine,- showing the end-"of the ro" 5, pinion, the ratchet-plate, and

cord on' the right side ofthe window.

Figure 3 is a sectional view, showing the same tixtures as attached to the left side.

Figure 4 is a horizontal section of the rollerinner shaft, pinions, and ratchet-plates, as attached.

A is the' wimlow-frame.

B the left, 'and C the right casing or jamq.

D is the sash in`rear ofthe curtain.

H E are `t-he ratchet-plates.

ll, the cord on the lett, side of the window, which is wrappednronntl thehuh F of pinion c, on the end'oi shaft b, and raises and lowers the roller and curtain together, the pinionsc and c running up or down on the ratchetplatesE when thccord is pulled in either direct-ion, the cord'running over the pulleys P and P' at the top and bottom of the. window-casing, which are in line with thefhubfof the pinion.

G, the cord onthe right side of the window, is wrapped around the sleeve g, on the end of the outer roller a, which tits loosely over the hub of pinion c". This'eord passes over similar pulleys, P anni L", andwhen pulled dow-n or up, turns the outside roller a., and winds up or nnwinds'curtain H, without .regn'd' tothe position of the roller on the window, the pinions c and c'y being held in position by the meshing of their teeth into the ratchet-plates E and the tension `of cords li and G.

A spring stop, s, shown at the bottom of the ratchetplates E, is fastened o n the back edge, and projects through a slot far enough inside to arrest the downward motion of the ends it of the pinions c and c', when the roller is drawn down to the bottom of the ratchet-plates, thus preventing it from .falling out.

In introducing the roller into its position, it is pushed up into the groove formed by the teeth and hack edge of the ratchet-plates from below, the spring stop s being beveled, for the purpose of allowing the projecting ends 'i t to pass over it.

lt will he seen, by reference to the drawing, that the upper ends of the ratchet-plates E are made solid, yas a seat for top pulleys iP. s these pulleys are always required at the saine point, and do not require any adjustment, as .the lower ones, l, do, in putting up the `tixtures, they are permanently attached to the top ends of the.ratcl1et-plates.

The inner and outer rollers are ymade of wood, s0`

that they can be cut to suit the window. The pinifyis are fastened to the inner shaft or roller I) by pins or screws, m, tig. 4.

e and e are ilanges turned up on the metal sleeves hand g, of the outer roller a, to prevent thecurtain from getting on the ends of' the. roller in winding.

By'ref'erence to fig. 4, it' will be observed that the sleeve h has a. collar, j, on its innerend, turned inside, to keep it in place on the piniou-hubf and give sufticient space for the cord F. v

The sleeve g has a collar, 11on its outer end, tuined outward, to prevent the cord G from wear against the teeth ofthe pinion c'.

The front or curved parts of the ratchet-plates, on which the teeth are cut,-are seen at k, and the back edge, which turns over the projecting 'ends of the pinions, is seeuat l, in the same figure.

A sucicnt clearance is given to the pinions and their endsi i. to move easily up or down inside the groove formed ny the back edge and ratchet-teeth.

I claim as my invention- 1. A double curtain-roller, provided with pinions o and c' and sleeves g and It, each part operated independently by cords wound one or more times upon the ends of the inner and outer roller, or uponparts attached to the saine, substantially as sli-own anddescribed, for the purpose hereinbefbre set forth.

2. The `pinions c and c', ratchet-plates E, sleeves Vhy and g, with collars j and n, and ian'ges e and e', constructed substantially as shown and described, for the purpose hereinbeforc set forth.
