CURTAIN-FIXTURE.

, SPECIFICATION forming part of Letters Patent No. 559,103, dated April 28, 1896.

Application filed November 1, 1895.: $erial No. 567,633. (No model.)

To aZZ whom, it may concern: v

Be it known that I,WILLIAM H. KIRKMAN, a citizen of the United States, residing at Berkeley, county of Alameda, State of California,

have invented an Improvement in Curtain- 1 passing over a' pulley at the top of the win dow frame or casing, whereby it is adapted to be raised or lowered and the curtain itself to be rolled up from the bottom or the top, in order to expose or to cover all or any portion of the window desired.

My invention consists in certain novel de: tails of improvement in a curtain-fixture of this olass,the objects of said improvements bein g generally to render the whole device practical, efficient, durable, and easily operated.

The particular objects of each improve ment will appear in the course of the following specification.

Referring to the accompanying drawings, Figure 1 is an elevation of my curtain-fixture. Fig. 2 is a longitudinal section of an adjustable hanger. Fig. 3 is an end view showing the roller-guide G. Fig. 4 is a view showing the device working in guides on the windowframe. Fig. 5 is a View showing the ferrule K with its guide-roller G. Fig. 6 is a view of the cord-clamp c.

A is the curtain, and B is the spring-actuated roller to which the curtain is secured and upon and from which it rolls and unrolls. This roller may be of any of the usual forms of spring-actuated ones, preferably the Hartshorn roller, either with or without its usual clutch, but preferably without, so that the tendency of the spring is unobstructed and is controlled merely by the cords which operate the device.

O is the cross-bar of the hanger, said crossbar having extending downwardly from its ends the arms a, one of which receives one end of the roller and the other receives the other end, oneof said arms being formed with a socket adapted to prevent the rotation of the pin fitting in it, and the other permitting said rotation in the usual manner of the brackets into which the Hartshorn roller is usually D is the suspending-wire of the hanger.

iThiS is secured at its extremities at or near f the extremities of the cross-bar of the hanger,

and to the center of said wire is secured. the

, cord E, which passes upwardly to and over a 1 pulley F at the top of the window-casing, and

thence downwardly to within reach of the operator. v

The connection of the cord with the suspending-wire may be a simple knot or tie,

but its best form is that here shown, consisting of a U-shaped clamp e fitted over the wire. The innersurfaces of the clamp-jaws are roughened to better hold the cord, and their outer surfaces are threaded to receive the tightening-nut e.

The pulley F is of the type of catch-rollers in common use, adapting the cord to be caught and controlled at any point desired, and said pulley needs no detailed description as its construction and function are well known.

It will now be seen that by operating the cord E the hanger with its attached roller and curtain may be raised or lowered to any point of the window-casing desired, and if now the lower portion of the curtain be held the-lowering of the hanger above will cause the spring-actuated roller to wind itself up on the curtain as it descends, thereby exposing the upper portion of the window, or if the hanger be held at a fixed point and the lower portion of the curtain be released it will roll up from below and expose the lower portion of the window. This operation is the same as in curtain-fixtures of this general class, and in order to hold and control the lower portion of the curtain I have a cord E, secured to its lower portion and extending down to and controlled by a catch-pulley F, similar to the catch-pulley F above. In cases, however,

a point of improvement in the presence and attachment of the suspending-wire D, forming part of the hanger.

It has been customary heretofore to attach the operating-cord to the center of the hanger, and in most cases it has been attached directly to the cross-bar of the hanger. This attachment brings the strain upon the center of the hanger, causing it to bend or get out of true, thereby causing its end arms, in which the sprin g-actuated curtain-roller is mounted, to clamp and bind thereon, preventing its free operation; but by my construction of the suspending-wire, having its extremities fitted to the cross-bar at a point near the latters extremities, the strain is distributed and carried outwardly to near the ends of said crossbar, thereby preventing undue strain and bending of the cross-bar, even though preserving the point of attachment of the cord at the center of the hanger, which is preferable to the employment of two cords attached at separated points to said hanger, as is sometimes done.

Another point of improvement in the suspending-wire as I have constructed it is that it is a spring and acts as such, and thereby relieves the curtain of much of the jar and strain placed upon it in operating it and prevents it from tearing out. To further this last result I do not attach the lower cord E to the bottom of the curtain directly, but I have a similar spring-wire D, attached at its ends to the lower wooden strip of the curtain, and to the center of this spring-wire I attach said lower cord by any suitable meanssuch, for example, as the fastening shown in connection with cord E-thereby providing for relief from jars and strains, as heretofore described.

In curtain-fixtures of the class to which my invention relates a difficulty has been encountered in the want of balance of the device. This is due to the fact that the curtainroller B has its very heavy actuating-spring located in one end of it, and when the attachment is made at the middle of the hanger, as is preferable for many reasons, the weight of the roller on one end throws the whole hanger out of balance and prevents the curtain from winding up true and straight.

The improvement in my invention consists in counterbalancing the unbalanced roller, and to this end I place the weightin the other end of the fixture. This weight in curtainrollers to be made in the future maybe placed directly in the roller itself but in adapting present devices to this result I prefer to place the weight in the cross-bar O of the hanger. Accordingly I have shown a weight \V in that end of the cross-bar opposite. that in which the actuating-spring is seated in the curtainroller. This weight may be of any suitable character; but in order to nicely adjust it and bring any particular device to its proper balance I make a groove or slot 0 in said crossbar and place the weight therein, so that it may be moved in or out farther from or nearer to the end of the cross-bar, thereby nicely regulating its position and adjusting the balance.

Another difliculty in curtain-fixtures of this class is the tendency of the hanger to bear in against the window-casin g and to roll up and down in contact therewith, thereby marring and injuring the surface of the casing, besides producing friction, tending to renderless easy the movements of the parts. This inward bearing of the device not only affects the hanger itself, but the curtain also, which, in moving up and down on its roller, comes in frictional contact with the window-casing and is therebysubjected to undue wear. To overcome this difficultyI place guides on the ends of the hanger which will come in contact with the window-casing and move thereon freely, causing the bracket and roller to work smoothly Without swaying, and at the same time keeping the roller and curtain far enough from the casing to prevent injury to the curtain. In order to reduce the friction to a minimum, these guides are in their best form roller-guides, such as are shown by the small wheels or rollers at G. In this case I have shown them as operating against the face of the window-casing in planes at right angles to the movement of the hanger but in other cases, as I have shown in Fig. 4, where it is desired to make the curtain and its hanger work up and down in grooves or channels II in the inner surfaces of the window-casing, I so attach them to the cross-bar, as I have shown at I, that theywork in planes parallel with the movement of the hanger, and in such cases I place similar rollers J on the ends of the lower wooden bar of the curtain, so that the curtain itself, as well as the hanger, moves up and down in the channels or groove H.

In some cases I fit the roller-guides to removable ferrules K, adapted to fit the ends of the cross-bar and to be adjusted thereon to suitable points, as may be required.

In some cases it is necessary to provide that the hanger shall be an adjustable onethat is, one which can be extended or contracted in its length to suit different curtains and rollers. In such cases, as I have shown in Fig. 2, the cross-bar of the hanger is composed of an outer tubular shell L and two opposing alined tubular cores M, fitted within said shell from opposite ends. The outer shell has an elongated slit Z in order to provide for the sliding adjustment of the counterbalancingweight \V heretofore mentioned, and the inner tubular cores are provided with elongated slits m, in one of which the suspending-screw w of the weight slides. These slits pass freely over the ends of the suspending-wire D to enable said cores to be withdrawn partially to lengthen the hanger or to be forced in farther to shorten it. Tapering screws N are fitted down through the outer shell, and by being caused to enter into the slits m of the inner cores expand said cores sufficiently to bind and hold them in the place to which they "are adjusted. The weight WV may be made fast at any point by tightening the screw to which suspends it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
