CHARLES E. GOODRICH, OF PIOOHE, NEVADA, ASSIGNORy OF VONE-HALF TO THOMAS J. OSBORNE, OF SAME PLACE.

CURTAIN- SPECIFICATION forming part of Letters Patent No. 509,078, dated November 21, 189.3. Application led December 17, 1892. Serial Naf/55,427. (No model.)

To all whom it may con/cern:

Be it known that I, CHARLES E. GooDRIoH, a citizen of the United States, residing at Pioche, in the county of Lincoln and State of Nevada, have invented a new and useful Curtain-Fixture, of which the following is a speci fioation.

This invention relates to curtain fixtures. The objects of the improvements herein described are to provide improved shade roller devices, by means of which the upper and lower portions of a Window can be automatically covered or uncovered simultane-` ously, or one at a time, so that ventilation from the tops of windows or other openings can be facilitated without inconveniencing or subjecting the occupants of rooms to drafts, dac. Also means are provided whereby light maybe admitted from either the top or the bottom of a window, as convenience mayrequire, so that tle curtains can be adj usted with respect to the sun, and the proper light can be admitted to the room, while at the same time not exposing the room to the direct rays of the sun.

With these and many other objects in view which will readily appear as the nature of 1the V invention is better understood, the same consists in the novel construction, combinationV and arrangement of parts hereinafter more fully described, illustrated and claimed. In the accompanying drawingsr-Figure'l is a front elevation showing the 'herein-de-v scribed curtain iixture in one of its adjusted positions on awindow. Fig. 2 is a'vertical. longitudinal sectional view on t-he line -x of Fig. 1. Fig. 3 is an enlarged longitudinal sectional view of the shade roller and its appurtenances. Fig. 4 is a detail in perspective of one of the grooved Winding rollers at one end of the shade roller. Fig. 5 is a similar view of one of the stationarysupporting brackets. Fig. 6 is a detail in perspective of one of the roller caps. Fig. 7 is a detail end view of one of the end pawl plates or disks. Fig. 8 is a detail plan view of one of t-he roller caps. Fig. 9 is a similar view of the loop end of the pull cord.

Referring to the accompanyl n g drawings A represents a .hollow shade roller of wood or other light material which accommodates the longitudinally disposed shaft B. The shaft B, extends through the entire length of the roller A,and projects slightlybeyond each end thereof, and carries atrsuch end the grooved winding wheels C. Each of the grooved winding wheels O, isarranged on a hub portion D, which projects beyond the outer sides of the wheels and into the ends of the roller, where the same are mounted on the projecting ends of the shaft B, and said winding wheels C, are so constructed that the base of their grooves form a circle, the diameter of which is about one half that of the roller A, while the outer edges or rims of the wheels form a slightly larger circle than the roller. the Winding Wheels O, is provided on both sides thereof with the notched collars E, the inner collar of which is designed to be engaged by means of the roller pawls F,`which are designed to arrest the motion of the roller and the recoil of the actuating spiral spring G. The spiral spring G. is of the ordinary construction, and one end thereof is fastened to the shaft B, while, the other endis secured to the roller A, so that the shaft with its attached wheels can revolve4 independently of the roller A. The arresting pawls F, are pivotally mounted or secured to the pawl disk or plate H, which is held to one end of the roller A, by means of the ferrulell, while the other end of the roller receives a similar ferrule I, which holds in position an opposite bearing disk H', which forms a journal lfor one end of the shaft B, and the opposite pawl disk forms a journal for the other end of the shaft.

Although l have described' the arresting pawl devices at one end of the roller, still it will be readily understood by those skilled in the art that the construction can be duplicated at the otherend'in order to secure a positive accuracy in thecatch and release of such pawl devices. The outer notched collar E, of one of the wheels C, is designed to be engaged by the stop pawl J, vpivotally mounted within one of the non-rotative cylindrical or disk wheel caps L. i The wheel caps L, are arranged to flt looselyv over the outer extended ends of the hubs D, so asto entirely inclose the grooved windingwheels C, and are provided in the rims thereof with' the slots or openings M, and the inner annular flanges N,

One of- IOC I which inclose therebetween on the roller the curtain or shade n, attached to the shade roller and adapted to be wound or unwound thereon. receive the rollei` supporting ribbons O. The said roller supporting ribbons O, are preferably of thin spring metal, and the lower ends thereof are secured in the transverse notches o, in the winding wheel C, and are designed to be wound up in the grooves of said wheels as the same revolve in one direction, or unwind therefrom as they revolve in the other direction', and said supporting ribbons O, which pass through the slots or openings in the wheel caps, have their upper ends secured in a stationary grooved supporting disk P. The supporting disks P, are also provided with transverse notches p, which receive the upper ends of the metal ribbons O and` are removably held in such notches by a wrap of the'ribbon upon itself in the grooves of said disks and said disks aresecured stationary on the supporting brackets Q, securei to the top of thewindowframeabove theupper end of the uppersash or window opening. It will be observed at this point, that by reason of the ribbons O, passing through the caps L, the latter are necessarily prevented from revolvingfA and therefore always have a fixed position as the ends of the roller and the pawls in said caps which engage the outer notched collars of the winding wheel serve to hold the roller at any point desired by preventing the same from turning in the direction induced by itsv spring, thus leaving it free to revolve in the opposite direction'.

It is ofcourse understood that the fixture is designed to be controlled in such a manner thattheroller may be lowered from the top of the window as far as may be desired leaving the remainder of the window covered, or by means of the spiral spring G, the roller A, may be revolved independently of the shaft B, so as to raise and lower the shade n, while at the same time the roller A, is heldin a stationary position with respect to the up and down movement of the same, at the option of the operator. This latter operation provides for uncovering the window at the bottom.

I'norder to hold the roller in a stationary position while operating the shade thereof, I employ a pull cord R, the lower end of which is provided with a knob r, and the upper end of which has connected thereto the metal loop or-ring S, which loosely engages one of the knobs at the outer extremities of the projecting-hubs D, so that the cord will not wind thereon. By grasping this cord with one hand while the roller is in a stationary posiftion, the operator prevents the ascent of the roller, which would follow from the rolling motion imparted to the roller by pulling down onV the curtain, and which would therefore, when a sufficient tension of the spring was reached, cause the end Wheels to turn .in a

direction so as to wind up the metal ribbon thereon and elevate the entire roller. It will be observed that while the roller is in this manner held stationary in au adjusted position, the curtain or shade may be wound or unwound'at will by pulllng down on the curtain or allowing it to ascend under the motion imparted to the roller by the spring, it being ot' course understood by those skilled in the art that by allowing the curtain to ascend slowly the pawls F, will engage the notched collar E, so as to stop the winding up of the shade or curtain at any position by preventing the roller from turning, and on the other hand by allowing the curtain to rapidly rise, the pawls will travel over the notches in the collars and not engage the same,A as is usual. It will be observed that when the roller is stopped by the pawls F, a further revolution in the direction induced by the spring will be checked by means of the stop pawl J, arranged in one of the w-heelcaps L. By releasing the cord R, and pulling down on the curtain, a revolving motion is necessarily imparted to roller, A, and this is continued until the tension of the spring is sufficient to overcome the weight ofthe roller, or

in other words the roller will revolve around the shaft until the tension of the spring is sufficient to cause the shaft-B, to also revolve, thereby turning the wheels C, and winding up the supporting ribbons, which causes the roller to ascend toward the top of the window, the tension of the spring being so vregu-lated, that the roller will reach its highest point at the top of the window before the curtain is entirely unwfound therefrom. The shade 0f course can be operated independently of the vertical movement of the roller at any point. The roller is lowered from the top by unwinding or pulling down on the shade or'fcurtain until the tension of the spring is sufficient to cause the-roller to begin'to ascend. By then quickly releasing the pressure i on the curtain byv raising the hand,l the roller in respense to its own gravity will quickly descend, unwinding itself from the supporting ribbons and Winding around itself in its descent, the curtain or shade. When the desired point in the descent of the curtain is reached, the curtain is checked by theV hand which will cause the stop pawl J, to drop into the outer notched collar E, thereby holding the roller stationary in its adjusted position. While this motion of the curtain is taking place, and also as the roller is ascending, the spring is necessarily inactive.

From the foregoing description it Will beapparent that the constructionspeciiied provides a curtain fixture, the roller of which can be automatically raised and lowered by simply grasping the curtain or shade, and also automatically checked or arrested at any adjusted position without touching the checking devices, and without releasing the hand` from the curtain or shade. This result is,

secured principallyby reason of the independent pawl device for one of the winding wheels.

Although I have described and illustrated the pawl device as a stationary disk cap alongside of one winding wheel and carrying a stop pawl, nevertheless `it will be apparent that the essential points are, that this pawl device be loose on the hub of the winding wheel which it engages, and be always retained in a fixed non-rotative position, so that the winding wheel engaged thereby can freely turn therein. Thetapes passing through the slots in the flange of said caps serve to hold the same stationary, but to secure the result described, it issimply necessary that the disk portion of the cap which carries the stop pawl be suitably mounted stationary alongside of the winding wheel having the outer pawl notches, whereby the automatic raising and lowering of the roller, by reason of the tension of the spring therein and its own gravity, can be effected by simply manipulating the curtain or shade as fully described.

Chapges in the form, proportion and the mirror 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, and desire to secure by Letters Patent, isV v 1.
