l and useful Improvements in Shade-Fixtures,

of which the following is a specification.

My invention relates to shade fixtures, and more specifically to a device for adjustably supporting a shade roller so as to permit of vertical adjustment of the latter in order to so position the shade as to secure the shade desired, and at the same time, to permit of the passage of light above or below the shade, and to permit of free ventilation where the windows are open.

A further .object is the production of a shade fixture as mentioned, which will be of simple construction and efcient in use.

Other objects will appear hereinafter.

With these objects in v-iew, the invention consists in the combinations and arrangements of parts hereinafter described and claimed. v

The invention will be best understood by reference to the accompanying drawings forming a part of this specication, and in which,

Figure 1 is a perspective view of a window equipped with a shade fixture embodying my invention, Fig. 2 is a central longitudinal section of the hanger of the device detached, Fig. 3 is a perspective view of one end of the hanger, Figs. 4L and 5 are enlarged transverse sections taken on lines fo-- and y-y respectively of Fig. 2, Fig. 6 is a top plan view of another form of the hanger, Fig. 7 is a central longitudinal section of the form shown in Fig. 6, Fig. 8 isV an enlarged transverse section taken on line s--z of Fig. 7, and Fig. 9 is a fragmental central section of one end of the hanger equipped with a guide roller which may be used in connection therewith if desired.

The preferred form of .construction as illustrated in the drawings, comprises an elongated hanger which is formed of two sheet metal sections 1 and 2, the inner ends of said sections-being telescoped so as to permit of relative sliding of said sections in orderto adjust the hanger longitudinally, so as to adapt the same to accommodate shade rollers of various lengths. The hanger section 2 is provided at its lower edges with outwardly and upwardly turned flanges 3 which slidably embrace the corresponding edges of section 1, said sections being substantially semi-circular in cross section in order to inclose the upper portion of the shade roller A arranged therein, and the upper side of the hanger is formed with a longitudinally extending rib or channel in order to reinforce or stiffen the same. At the outer end of each of the hanger sections are provided inwardly extending ears 4l which are rigidly connected together by an eyelet, the eyelets at the opposite ends of the

hangers forming openings

5 and 5 for engagernent with the respective ends of the studs of the shade roller.

The hanger is suspended by means of a cord or flexible element 6, one end of which engages with a channel member 7 which is mounted upon the hanger intermediate the ends thereof, said member 7 being provided at its lower edges with inwardly and upwardly turned flanges 8 which slidably embrace the lower edges of the section 2. Said member 7 is releasably locked in position by means of screws 9 which engage against the upper side of hanger section 1. The arrangement is such, that the member 7 may be adjusted longitudinally of the hanger in order to position the same centrally of the hanger after the latter has been adjusted longitudinally in order to accommodate a shade roller of a particular length, said member 7, after being adjusted to the center of the hanger, being secured in this position by means of screws 9. The end of cord 6 engaging with the member 7 passes through an opening 10 provided in the upper side of said member, said cord being provided at its lower end with a knot as shown, which serves to lock said cord against upward movement through the opening 10.

In order to prevent wear of the cord by reason of engagement thereof .with the edges of opening 10, a metallic sleeve or bushing 11 is provided upon the cord immediately above the knot thereof, as clearly shown in Fig. 4. With this arrangement, it will be seen, that the member 11 will take up all wear and thus extend the life of the cord. At the front side of themember 7 is provided an opening 12 through which the cord may be passed lin order to effect engagement thereof with the opening 10 or disengagement of said cord from said opening, said opening 12 being large enough to permit the passage of theV knot provided at the lower end of said cord. The upper side of the member 7 is spaced from the upper side of the hanger, as shown,'so as to permit of the uninterrupted passage of the cord from opening 10 to opening 12 and vice versa.

The cord 6 passes upwardly from the member T over a pulley 13 of the usual catchroller type in common use at the present time which is adapted to engage and clamp the cord at any point desired, the construction of this pulley being well known so as to not require detail description. After passing over the pulley 13, which is secured centrally to the upper end of the window frame, the cord passes downwardly under a pulley 13 of corresponding form, which is secured centrally to the lower end of the window frame, after which said cord passes upwardly for engagement with the lower end of the window shade, as clearly shown in Fig. 1.

Slidably mounted at the upper side of the hanger is a channel member 14 having inwardly and upwardly turned ianges 15 at its lower edges which rembrace the lower edges of section 2. Arranged in the upper side of the member 14 is a weight 16 secured thereto by means of a screw 17, said screw serving also as a means of securing the member 14 in positions of longitudinal adjustment upon the hanger. The member 14 and the weight member 16 carried thereby, serve as a means of counterbalancing the weight ,of the-actuating spring of the shade roller,

this spring being usually mounted in one end of the roller. Without the provision of counterbalancing means, Vthe weight of the actuating' spring of the roller would cause one end of the latter to rock downwardly'so as to destroy the operative horizontal position of the shade and preclude the possibility of the shade being readily rolled thereon. With the provision of the counterbalancing device as mentioned, after the shade roller has been mounted in the hanger, the member 16 needs only to be slid longitudinally' upon the yhanger until the hanger is so balanced as to assume a horizontal position whereupon said member `16 is locked by tighteningthe screw 17. Vith this'arrangement then, it will be seen that the proper horizontal position of the hanger and shade roller carried lthereby may be readily main-l tained. f

Provided at the ends of the hanger and at the rearward side thereof, or at the points where `said hanger engages against or contacts with the window frame, are projecting ,studs 18 covered with Vplush or other antifriction or nonabrasive material which serve as ,a ,protection to prevent marring of the window frame in the vertical adjustment of the shade hanger.

In the form shown in Figs. 6, 7 and 8, the hanger is formed of telescoping sections 1 and 2, the section 1 being provided at its lower edges .with inwardly and upwardly turned flanges 8 which slidably embrace the corresponding edges of section 2f, the arrangement being substantially the same as that before described. At the outer ends of the sections 1 and 2 are provided inwardly extending ears 4 in which are formed the sockets or

openings

5 and 5 for engagement with the shade roller studs, as above set forth. In this form, however, the members 7 and 16 are dispensed with and in lieu of the former, a bar 19 is arranged in they reinforcing rib provided at the upper side the cord 6 with the hanger, or disengagement thereof from the hanger may vbe effected only when the shade roller isV de tached, which is not the case in the form first described where connection or disconnection of the suspending cord may be Ieffected without disturbing the shade roller which may be mounted inthe hanger.

In lieu of the eounterbalancing device of the form first described, inthe modified Y form a counter-balancing weight ,23 is employed which is slidably mounted in the rib provided at the upper side of the hanger, being secured in positions of adjustment by means of screws 24 which pass through-theV slots 21. In the form last described, it will be seen that the memberwith which the vsuspending eord is connected, and the counterbalancing device, are concealed within ythe hanger which results in a neat and pleasing design.

lVhere the device is used in railway cars, or in connection with windows havingv vertical grooves at the inner sides Vof the vertical bars of the frames thereof, the hanger will be provided with rollers 25 at the respective ends thereof for engagement withV said grooves, in order to guide the hanger in its vertical movement. The rollers 25 are mounted at the ends of the hanger so that the outer portions thereof project from the Y corresponding end surfaces of the hanger, as clearly shown in Fig. 9, in order to adapt said rollers for engagement with the window framegrooves, as will be readily understood.

i Y'Vhile I have illustrated'and described the preferred forms of construction for carrying my invention into effect, these are capable of variation and modification without departing` from the spirit of the invention. I, therefore, do not Wish to be limited to the precise details or' construction set forth,

'f but desire to avail myself of such variations means comprising a member of substantially inverted U-shape, the ends of said member embracing the longitudinal edges of said hanger, the central portion of said member being spaced from the upper side of said' hanger and having an opening in the upper portion thereof through which the lower end of said suspending element extends; an enlargement at the lower end of said suspending element of greater diameter than said opening and adapted to engage against the under side of said upper portion of said member, there being an opening in the front o side of said member adapted to permit of the passage of said suspending element in engaging the same with or disengaging the same from said lirst mentioned opening, said last mentioned opening being of greater diameter than said enlargement, and clamping screws threaded in said member and contacting with said hanger substantially as described.

In testimony whereof I have signed my .name to this specication in the presence of two subscribing witnesses.
