CURTAIN- FIXTURE.

SPECIFICATION forming part of Letters Patent No. 513,171, dated January 23, 1894.

Application filed December 14, 1892. Serial No. 455,175. (No model.)

operated with only one hand so as to allow the roller to be raised and lowered to any part of the Window, and the curtain or shade to be extended from the roller any distance, in order to provide efficientmeans lfor allowing light and air to enter the upper portion of the window, and in short to providemeans for adjusting the rollerand its vshade to anyV j position.

With these and other objects in View which will readily appear as the nature of theinvention is better understood, the same consists in the novel construction,'combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings, Figure l is a perspective view of a curtain iixture embodying the principles of my invention, and affixed to the window. Fig. V2 is a central vertical sectional view thereof. Fig. 3 isa detail vertical sectional view adjacent to one of the roller bracket clutches. Fig. t is a detail sectional view through one end of the roller. Fig. 5 is a detail in perspective of one of the roller bracket clutches. Fig. 6 is a similar view of, one of the shade clutches or arms affixed to one end of the shade slat. Fig. 7 is a detail in perspective andl in section of a modification showing the guide rod having a metal covering and jointed thereby.

Fig. Sis a detail sectional `view of one end of the roller and its moving journal.

Referring' to the accompanying drawings, A represents a window frame of ordinary: construction in which slide the usual sashes and to opposite inner sides of said frame are secured the vertical circular'guide rods B, extending from the top to the bottom thereof to form a guide and support for the Xtures curtain or shade.

kto be described. If so desired, as illustrated' in Fig. 7, the said guide rods may be made in suitable lengths and iuclosed in the metal sleeves b, inside of which the terminals of the rod sections terminate, as illustrated in said figure, so that there may be a continuous guide at opposite inner sides of the window frame. Arranged to move on said` guides are the opposite connected roller bracketl clutches C. The roller bracket clutches C, are provided with the bearing notches D formed at theinner ends thereof and adapted to receive the journal ends of the pawlless shade roller E. The shade roller E, carries the usual actuating spring F, connected thereto at one end,

and at its other end to the stationary rod or journal G, squared at its outer end to rest in the notch of one of said brackets so as to hold the salme stationary, and in order to throw the tension of the spring onto the roller at all times,the usual pawlsbeing entirelydispensed with, while at the other end of the roller is arrangedthe short moving journal g, whlch 1s designed to work in the bearing notch ofthe opposite bracket. An ordinary curtain or shade H, winds and unwinds on said roller, and it will be observed at this point that by reason of the absence of the usual pawls to hold the roller, the tension of the spring arranged therein always tends to wind up the Each of the opposlte movable roller brackets C is extended into the clutch arms I, in which are formed at one side near Ytheir outer extremities, the circular clutch openings or notches J, which embrace the opposite guide rods and which allow vthe said brackets to slide freely thereover, when vat right angles thereto. The entremlties of said clutch arms are provided with right an- 'gularly disposed down-turned stops K, which are arranged to strike the outer sides of the guide rods lwhen the brackets are raised toa position at right angles to the guide rods, and are thus held in such position so as to ralse and lower the roller as the brackets are raised and lowered. Secured to the opposite roller brackets C, at their innerv ends, inside of the opposite guide rods, are thel opposite angle irons or strips K', which depend from the 1nwardly standing roller brackets and stand outward toward the front end ofsaidV brackets, and have their outer ends connected to ICO the opposite ends of the horizontal connecting bar L, which serves to connect the two roller brackets in order that their movement shall be simultaneous. Centrally secured tothe horizontal connecting bar L, is the pull handle M. The pull handle M, is provided with a suitable finger grasp m, and has an upwardly extended arm N, which curves rearwardly above the roller so that the eye n, at the upper end of the same lies in a plane back of the inner bearing ends of the roller brackets, and has connected to such eye if necessary an operatin g cord O. The operating cord O, passes over the swivelcd guide pulley o, arranged at theV top of the window frame and has its other end free to be controlled by a person, or which may be connected to the finger grasp referred to, so that the roller can be raised and lowered entirely by means of the cord, in case the window frame is too high for the person to manipulate the raising and lowering of the roller. Now it will be readily seen that, supposing the roller to be at the top of the window, to lower the roller, by grasping the pull handle M, on the horizontal connecting bar and pressing said bar toward the sashes, the inner bearing ends carrying the roller will be elevated, so that the brackets are lifted at a right angle to the guide rod, which allows the roller and the brackets to freely slide on the rods to any position. By relieving the cross bar of the inward pressure, the weight of the roller and the tension of the spring therein, instantly depresses the inner bearing ends of the roller brackets and causes the clutch openings or notches J, therein to cramp on the guide rods and thereby tightly hold the roller in such adj usted position. With the roller in any adjusted position, the curtain or shade I-I, can also be raised or lowered to any desired point. The curtain or shade H, carries at its lower end the usual bottom slat P, to the opposite ends of which are secured the inner flanged ends of the opposite o-standing shade clutch arms Q. The opposite clutch arms Q, and which are disposed at right angles to the Slat are constructed in any suitable shape, but are provided with the outer clutch ends R, in which are formed at one side the circular clutch openings or notches r which embrace the opposite guide rods B, and are designed u to cramp thereon and hold the shade or curtain in any position. or button S, is secured to the shade slat P, at the center thereof and provides means for relieving the clutch arms of the opposite guide rods by bringing the same to a position at right angles thereto in order to raise an lower the shade or curtain.

`It will be apparent that owing to the absence of pawls in the spring roller,the tension of the spring therein will therefore constantly hold the shade or curtain smooth and straight and prevent the wind from blowing the same about when the window is open. The tension of said spring also draws up the A suitable thumb piece inner ends of the shade clutch arms and causes the outer ends thereof to bind `or cramp on the guide rods thereby holdin gthc shade orcurtain fixed to an adjusted position." The shade or curtain can be moved up or down by simply relieving the clutch arms of the guide rods. At this point it may be well to observe that the operation just described for raising and lowering the shade and holding the saine in any adjusted position by means of the shade clutch arms Q, well adapts the herein-described device for car window use, so that the shade or curtain will always be held smooth and straight by reason of the tension of the pawlless spring roller, and will not slip from its adjusted position by reason of the strong drafts or winds usually rushing through open car windows. When used in connection with car windows, the vertically adjustable support for the shade roller need not be employed, but the said roller may be supported stationary in the ordinary manner.

From the construction herein described, it will be seen that the fixture is well adapted for car windows inasmuch asjarring will not displace any of the parts thereof, and that the absence of pawls not only renders the fixture more positive in action but also provides a simpler and more useful construction.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y 1. In a curtain fixture, opposite guide rods, opposite connected roller brackets having clutch openings or notches embracing the opposite guide rods, a pawlless spring-actuated shade roller mounted in said brackets, and clutches for the lower end of the shade, substantially as set forth.
