CURTAIN-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 716,060, dated December 16, 1.902. Application filed September 12,1902. Serial No. 123,066. (No model.)

To all whom it may concern:

Be it known that'I, OoRYnoN B. LAKIN, a citizen of the United States, residing at Washington, in the 'District Vof Columbia, have made certain new and useful Improvements in Curtain-Fixtures, of which the following is a specification.

Myinvention is an improvementin curtainfiXtures, and has for an object, among others, to provide a novelconstruction by which the curtain may be raised and lowered as usual, may be secured with its roller at the top of the window or at any lower point, and can be readily operated from one position to t-he other in such manner as to permit light from the upper or lower portion of the window or from the upper and lower portion of the window; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is an elevation of the upper portion of a window provided with my invention with the curtain and its roller secured in its uppermost position.A Fig. 2.is a similar view with the curtain-roller lowered in such manner as to freely admit light at the upper portion of the window. Fig.` 3 is an elevation of the bracket shown at the left in Fig. 1, the curtain-roller beingin place. Fig. 4 is a similar view of the bracket shown at the right in Fig. 1.

left in Fig. 1. Fig. 6 is a detail view, partly in section, of `the tension device for holding.

diagrammatic view indicating the disposition.

Fig. 5 is a detail'per-4 spective view of the bracket shown at thej of the cords forsupportingand operating the" curtain-roller. j

The curtain A and its roller B may be of ordinary construction, the latter being of what is known as the Hartshorn type, having at one endtheround stud C and the cordpulley C and at its other end the angular stud D and the cord-pulley D. These pulleys C and D are fixed to the opposite ends `of the roller B. The brackets E and F are respectively at the left and right hand side of the window, (see Fig. 1,) correspondingto the studs D and C, and they are provided with the downwardly opening and flared seats e and f for the studs D and C., the seat e being angular at its upper end to hold the stud D from turning and the seat f being` rounded at its upper side to form a bearing in which the stud C can freely turn. The

brackets E and F in the seats e and f corre- `and will drop by gravityout of said seats, so

the roller when up in the position shown in Figs. 1, 3, and 4 can be operated after the fashion of an ordinary Hartshorn roller and yet can be freely lowered from such position to that shown in Fig. 2 when it is desired to admit light at the top of the window. It will be understood, therefore, that by constructing the brackets with the downwardly-opening seats e and f I am able to adjust the curtain -roller up to the position shown in Fig. 1, where it can be operated as a Hartshorn roller, and at the same time can by the means presently described lower the curtain-roller to the position shown in Fig. 2 or to any other lower position desired and adjust the curtain to admit light and air at any portion of the window-opening. The bracket E (shown at the left in Fig. l) has its seat e provided at its upper end with the angular bearing e' for the square stud D of the roller B and opens freely downward from said bearing e', so the roller can readily adjust by gravity out of the seat e. It may be Vdesirable to slightly swell the bracket-wing at e2 adjacent to the seat e, as shown in Fig. 5, for

the purpose of gaining some strength, and it `may be desirable to further swell the bracket adjacent to the seat, as shown at eii in Fig. 7,

when the bracket is formed, as shown in Fig.

7,-to be secured against the inner face of the side of the window-frame, the construction shown atei affording room for the stud D of the roller, as will be understood from the said Fig. 7.

The bracket E (shown in Fig. 5) is formed from a plate of metal with the wings E and E2, the latter being at a right angle to the wing E' and formed to be secured against the face of the window-frame, as shown in Figs. 1 and 2. At its outer edge the plate E' is provided with a projecting lug E3, which is bent at a right angle to the wing E', and a similar lug E4v is cut out of the wing E, as shown at e4, and bent to a position parallel with the lug E3, the lugs E3 and E4 providing a bearing for the guide-pulley G for the cord,

' which supports the left-hand end of the curjournaled in this bracket for the cords which support the right and left hand end of the roller B, as will be understood from Figs. l, 2, and 8. Cords I and J are provided for supporting, respectively, the left and right hand ends-of the roller B. The cord l is secured at I in connection with the window-frame at a point above the bearing e. This connection may be effected through the bracket E, which is provided at i' with a lug, to which the end I of the cord may be fastened. cord I extends thence down under the pulley D of the roller B, thence up over the bracketpulley G, thence across the window-frame over the pulley I-I, and thence down, where it is connected with the spring-tension device K. (Shown in Figs. 2 and 6.) The cord Jis secured at its upper end at J/ in connection with the window-frame, (it may be to thelug j on the bracket F, as shown in Fig. 4,) and extends thence downwardly under the rollerpulley C', thence up over the guide-pulley H, and thence down to the tension device K, the depending lengths I2 and J2 of the cords being manipulated together in connection with the tension device K, so the said tension device will exert a tension upon the cords J and K in such manner as to hold the same in any desired adjustment and so secure the curtain up in the bearings e and f or in any lower position to which the curtain may be adjusted. This is an important feature of my invention-that is to say, the provision, in connection with brackets having downwardly-opening seats for the studs of the curtain-roller, of tension devices for holding the cords which suspend the curtain so the curtain may be held by said cords through the aid of the tension devices up in the said bearings o1l down in any desired position.

The tension devices, as shown in Fig. 6, include a casing L, which may be secured to the window-frame, a plunger M, and a spring N, by which the plunger is held normally downward or against upward movement. At its upper end the plunger M has a roller O, grooved at its center O. and bearing above a plate or abutment O2 the cords I and J, passlng under the roller O and moving freely The when in the grooved portion O of the roller, but capable of adjustment between the ungrooved end portions of the roller and the abutment O2, so the cords may be secured whenever desired. In clamping the cord between the roller O and the plate O2 the cord may be drawn to one side of the groove Oin said roller, or, if desired, the ordinary clamping-roller having a cam-shaped groove commonly used in connection with curtain-cords may be used in place of the roller O, the specilic construction of the said roller O taken alone forming no part of my invention. By this means the curtain may be raised to the position shown in Fig. l or lowered to the position shown in Fig. 2, and in either position will be held by the clamping lof the cords I and J by the tension device K. At the same time when the roller is held up in the position shown in Fig. l the tension deviceK 0perates to hold the said roller in such position in a yielding manner, so the roller can turn in the bearing f to permit the adjustment of the curtain up or down on the roller, as is usual with the Hartshorn fixtures.

In the operation of my curtain-fixture the curtain can rst be adjusted to the .position shown in Fig. l, the shade then being pulled down to the bottom of the window or to any intermediate position, provided it may be desired to admit light and air at the lower portion of the window. Then by releasing the cords I and J from the clamping action of the tension device the said cords may be released and the roller lowered to the position shown in Fig. 2 or to any other lower position. In so doing the roller will turn in the cords I and J, so that as the roller B is lowered it will wind up the shade from above, so that the lower portion of the shade will not be disturbed from the position to which it has been adjusted. Then as the cords I and J are adjusted to raise the roller BI they willy turn the said roller, unwinding the topl portion of the shade as the roller approaches the position shown in Fig. l. To permit the cords I and J to wind up the shade with certainty, it is preferred to groove the curtainlrollers D and C', so that the cords I and J will it tightly therein in such manner as to insure the turning of the roller by the operation of the cords, as before described.

It will be understood, especially from Figs. 5 and 7, that the guide-pulleys are grooved with V-shaped grooves, so the cord when properly fitted thereto will bind with sufticient force to insure the turning'of the pulleys C and D by the action ot the cords when the curtain-roller is lowered out of the brackets E and F. In this connection it will be understood, especially from Fig. 8, that the cords I and J do not pass entirely around the pulleys D and C', but only one-half around the said pulleys, so that when the roller B is adjusted up into its brackets, as shown in Fig. l, the cords I and J will not prevent the turning of said pulleys with the roller in the IOO operation of the roller in connection with the ordinary Hartshorn spring and in the manner common to such spring, the yielding tension exerted longitudinally on the cords permitting the operation ot the roller after the fashion of the ordinary Hatshorn roller when the parts are in the position shown in Fig. 1. It will also be understood that I provide pulleys at the opposite ends and xed to -the roller B, so that in the operation of the curtain from the position shown in Fig. 1 to that shownin Fig. 2, and vice versa, both ends of the roller are positively operated by the cords, as desired.

The construction is simple, easily applied and operated, possesses no parts likely to get out of' order, and enables the curtain to be quickly adjusted to secure light and ail at the upperportion of the window, at the lower portion of the window, or at both said portions, as may be desired by the user. It will be noticed the invention can be cheaply made and applied, involving no greater expense than the ordinary curtain-fixture.

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