CURTAIN-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 465,403, dated December 15, 1891.

Application filed October 1, 1 8 91.

To all whom it may concern:

Be it known that I, LEE YANOEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have 5 invented certain new and useful Improvements in Curtain-Fixtures, of which the following, when taken in connection with the accompanying drawings, is a description sufficient to enable those skilled in the art to 1o make and use the same.

My invention relates to the method of hanging curtains, shades, maps, and other like articles before windows or other objects wherein the curtain, shade, or map is mounted on a r 5 roller of the kind known in the art as springroller curtain fiXtures-that is to say, a roller having a curtain, shade, or map secured and rolled around the outside thereof and a coil-spring therein, one end of the coil-spring 2o being secured to and-rotating with the roller and the other end secured to a non-rotatable rod or shaft having a square end projecting outside vof the roller, with a dog or dogs on the roller adapted to abut against projections therefor, secured to the non-rotatable shaft, whereby the roller may be turned, thereby partially winding the spring, and held in such position by the dogs, or one of them, on the roller engaging with the projection on the 3o stationary shaft, while such dog can be released by turning the roller, so as to wind the spring stillfurther, and releasing'it suddenly, thereby permitting it to turn or be turned backward by the elasticity of the spring.

rlhe object of my invention is to obtain fixtures whereby a curtain, shade, or map can be mounted on a roller of the kind named, and when so mounted such curtain, shade, o1' map can be unrolled from such roller and 4o held in position in the ordinary way in which such curtain, shade, or map when wound on a roller of the character described is now held, and in addition thereto, when the curtain, shade, or map is wholly or partially unrolled from such roller, the roller itself can be lowered, and in such lowering of the roller the curtain, shade, or map will be automatically wound around it, the bottom of the curtain, shade, or map, or so much thereof as is Serial No. 407,372. (No model.)

no t wound around the roller, remaining sta- 5o tionary.

By this invention I am enabled at any time when the curtain, shade, or map is unrolled or partially unrolled from the roller to roll such curtain, shade, or map on such roller, from the top thereof, by moving the roller down toward the unrolled portion of the curtain, shade, or map and leave the window or opening or object before which the curtain, shade, or map is placed exposed.

I have illustrated my invention by the drawings accompanying and forming a part hereof, in which- Figure l is an elevation of a curtain or shade hung by my device before a windowopening, the curtain partially unrolled from the roller, with dotted lines indicating the roller lowered a short distance; Fig. 2, a crosssection on line 2 2 of Fig. l; Fig. 3, a crosssection on line 3 3 of Fig. l, showing an end 7o elevation of the roller and fixtures; Fig. 4, a front elevation of one end of the roller and the end illustrated in Fig. 3; Fig. 5, a crosssection on line 5 5 of Fig. 4.

The same letter of reference is used to indicate a given part where more than one view thereof is shown in the different figures of the drawings.

A is a window before which I have illustrated a curtain or shade hung with my device. 8c

A A are the sides of the window-frame casing; A2, the top of the window-frame casing.

B is the roller on which the curtain or shade is Wound. l

C is the curtain or shade. 8

D is a roller secured rigidly to the shaft D. Shaft D extends in roller B, and to it is secured one end of the coiled spring ordinarily placed in the curtain-roller of this kind.

D2 is a roller loosely mounted on the roller 9o B at the opposite end thereof of roller'D.

d is a groove around the rollers D D2.

d is the squared end of the shaft D.

d2 d2 are abutments on shaft D', and d3 d3 are dogs pivotally mounted on roller B, V95 adapted to engage with the abutments d2 d2.

E is an abutment having a flaring slot therein, such abutment being secured to the window-frame casing and such slot adapted to contain therein and hold from revolving the squared end d of the shaft D.

F is a grooved pulley mounted in frame F on the top bar A2 of the window-frame casing and ordinarily, though not necessarily, near the center thereof.

G G are pulleys revolubly mounted on the bar A2 of the window-frame casing near the ends thereof and over the pulleys D D2, respectively.

H I-I are cordsV passing over the grooved pulley F and over the pulleys G G', respectively, from thence around the pulleys D D2, respectively, and from thence back to the casing-bar A2, to which they are secured.

The pulleys G G are made revoluble to lessen the wear and friction of the cords H H', respectively, resulting where such pulleys are non-revoluble, and hence where the curtain, shade, or map mounted by the use of my device is not particularly heavy such idlers G G need not be revoluble, and, if preferred, an eyebolt may be used in place thereof.

It will be observed that in order to obtain the result sought by me the cord H should not slip on pulley D, and it is desirable that such cord H should pass around the pulley D at least once to insure no slipping thereon, and as usually mounted by me this cord passes around the pulley D in the groove CZ thereof more than once and a half, as illustrated in Fig. 5 of the drawings.

I is a lever pivoted to the frame F, in which the roller F is mounted.

I is an arm of lever I and has at the end thereof eye I2, through which the cords H H H H are allowed to pass over the pulley F the roller B will be lowered. 'During the lowering thereof the pulley D will turn in the direction indicated by the arrow in Figs. 2 and 5, and, the roller turning with such pulley D, the curtain or shade C is wound around the roller, the stock C at the bottom of the roller remaining stationary. Vhen the roller is lowered as far as desired, the cords H H are against pinched against the pulley F by the arm vl of the lock I, and thereby locked, and such roller will remain in its position any desired length of time.

When it is desired to raise the curtain-roller B into position so that the squared end d of shaft D is in the slot e of the catch E, such raising is done by drawing upon cords H H' and the roller made to remain stationary by locking the cords H H with the lock I in the manner described. When in this position, the. curtain C may be unwound sufficiently from the curtain-roller B to unlock the dogs d2 cl3 from abutments d2 d2, when the spring contained in the roller will cause it to turn, and so Wind the curtain thereon in the ordinary Way.

I do not claim as my invention the manner in which the shaft D is locked and unlocked from the roller B, with the coil-spring intervening between such shaft and roller, as such device is old and well known in-t'he art and is used by me to perform the functions it ordinarily performs; but

What I do claim, and desire to secure by Letters Patent, is-

A curtain-fixture consisting of aroller having a coiled spring therein and a shaft, one end of the coiled spring attached to the roller and the other end to the shaft, such shaft projecting beyond one end of the roller and having an abutment thereon and a square end, and dogs pivotally' mounted on the end of the roller, adapted to engage with the abutment on the shaft, in combination with a pulley loosely mounted on one end of the roller and a pulley rigidly mounted on the shaft at the other end of the roller, so that the square end of the shaft extends beyond the pulley, cords secured, respectively, at one end to the window-casing over and extending downward to and around the pulleys on the curtain-roller, from thence upward and over an abutment on the window-casingover such pulleys, respectively, and from thence to and over a single abutment, and a slotted abutment on the window-casing, adapted to receive the square end of the shaft when the roller is drawn into its extreme upward position, whereby when the cords are moved the pulleys and curtain -roller suspended thereby will move and the pulley on the shaft, with the curtain-roller locked thereto, will be rotated during such movement,substantially as described.

LEE YANGEY.

In presence of- CHARLES T. BROWN, ABEL W. SCRANTON.
