ADJUSTABLE SHADE SUPPORT.

Application filed May 25, 1917, Serial No. 170,817. ReneWed OctOber 30, 1922. Serial No. 598,016

To all whom it may concern:

Be it known that I, r- USTIN D. BRIXEY, a citizen of the United States, residing at city, county, and State of New York, have invented new and useful Improvements in Adjustable Shade Supports, of which the following is a specification.

This invention relates to shade roller sup ports and securing means, and particularly to structures wherein the shade roller is adjustably mounted.

The present invention is an improvement upon the structures of my application Serial No. 66,256, filed December 11th, 1915.

One object of the invention is to so construct the shade roller supporting brackets as to relieve them of binding in their guides under the stress of pull on the supporting cord or weight of the roller, shade, etc. thereby contributing to the smoothness and ease of operation.

A further object of the invention is to provide an arrangement and construction of cord guides and holders such that the shade may be readily adjusted to cover any desired area at any desired portion of the window.

A further object of the invention is to provide an apparatus wherein, if one end of the shade roller falls, it will not come against the window frame so asto pry on the bracket and strain or perhaps break it, while at the same time preventing'a toggle joint action operated on by the weight of the shade, roller, etc, tending to jam and bind the bracket in its guide or perhaps break it.

Another object of the invention is to provide means for reducing the noise and shock to the parts when-the bracket comes to the end of its guide as when the bracket falls or is lowered rapidly.

Other and ancillary objects of the invention will appear hereinafter.

Referring to the drawings, and first-to Figures 1 to 12 inclusive, the apparatus comprises a window frame A, a shade roller B supported in'adjustable brackets C and D and. carrying the shade E. The'bracke'ts C and D are guided by the respective'bracket guides F and G secured to opposite sides of the window frame, while the supporting cords H and I pass over guides K and L at the corners of the frame and at the tops of the bracket guides. The cords then pass over the guides M, secured to the top of the window frame at substantially its middle point whence they pass downwardly behind the shade, merging into a single cord which passes through a cord stop 0, and thence to a cord stop P secured to the shade at substantially its middle point.

The bracket C comprises a plate 1 on which are rotatably mounted wheels 2 and 3. These wheels are beveled at their peripheries as shown, so as to closely fit within the grooves a and 5 in the guides C as shown most clearly in Fig. 9. The wheels may be made from celluloid which provides an eiiicient, durable and non-sonorous structure. From the front of the plate 1 extends an arm 6, which is offset downwardly. as shown in Figs. 2 and 4 and is also offset laterally as shown in Figs. 5 and 9 so as to bring the point of support of the shade roller more nearly in the plane of the bracket wheels. At the lower end of the arm 6 is pivoted a pintle-supporting arm 7, having a recess 8 into which projects the usual squared pintle 9 of a Hartshorn type of shade roller, which is fixed therein by means of a set screw 10. The top of the bracket is cut away at 11 to form clearance for the knot 12 tied in the end of the cord H, just below the opening 13 in the offset ear 141 of the body 1. This forms the connection of the lifting cord with the bracket as the knot 12 cannot pass through the hole 13, it being observed that the ear is offset in the direction of the plane of the bracket wheels.

The offsetting of the cord connection and .the shade support toward the plane of. the

bracket wheels reduces the tendency to twist the wheels in the guide by pull upon the cord or the bearing down of the weight of the roller, shade, etc., so that binding of the wheels in the guide is lessened and the case of operation enhanced.

The other bracket D comprises a plate 15 in which are rotatably mounted wheels 16 and 17 of celluloid which enter within the guide G. the peripheries of the wheels being beveled and fitting snugly in grooves 18 and 19 of the guide in a manner as already referred to in connection with the rollers of the other bracket C. There is also a forwardly projecting arm 20 from the plate 15 and, like the arm 6 of the bracket C, it is offset laterally for a purpose as referred to in connection with the other bracket. In stead of being offset downwardly, however, the arm 20 is offset upwardly and at its upper end has pivoted a depending arm 21 for engaging with and supporting the shade roller pintle. This arm 21 has a channel 22 adapted to receive the ball and having a bed 23 therefor at its lower end. At the edge or mouth of the channel are ledges or flanges 2 1, which prevent the passage of a ball litting within the channel. At the upper end of the channel, however, the ledges are cut away to. form an opening 25 through which the ball can be removed. The pintle of the shade roller, corresponding to the usual Hartshorn roller of round'section so as to permit rotation, comprises a neck 26 secured at one end to the shade roller and at the other end carries the ball 27 adapted to be entered through the opening 25 to the channel 22 whence it gravitates to the bottom thereof, finding in its lower end a bed so that the pintle is secured to the bracket by a universal joint.

In installing the shade roller, the squared pintle is secured in the bracket C as described. If in entering the other pintle in the bracket D the end of the roller is accidentally dropped, the pivoted arm 7 being upstanding from its pivot, will. swing the roller end away from the window frame so that theroller will clear the frame in swinging into a vertical position so that the prying upon the bracket which would take place if the roller came against the frame before this position was reached, is avoided. At the other bracket, however, the pintlehaving a movable connection. with its pivoted supporting arm, if the arm were upstanding a toggle would be formed by the roller and the pivoted arm supporting the pintle whenever the angle between the axis of the roller and they arm was greater than a right angle, and this toggle would tend to be straightened by the weight of the roller and supported parts, this force being much magnified in its application to the bracket by the toggle so that a considerable force is exerted thereon. tending to bind the bracket in its guides and'perhaps break some of the parts. By making the pivoted pintle supporting arm depending this difliculty is avoided and furthermore the movable connection of the pintle with its supporting arm is more satisfactorily accomplished and by a simpler structure.

Secured to an ear 28 substantially as described in connection with the bracket D, is

a supporting cord I having the knot, 28 at its end. The bracket K is secured .to the frame at its corner above the bracket guide F and comprises a frame 29 in which is pivoted a pulley 30 acting as a guide for the cord H. Similarly-the bracket L, comprising a frame 31 in which is mounted a rotatable pulley 32, acts as a guide for the cordI at the upper end of the bracket guide C. The guide M comprises the frame 33 in which are rotatably mounted pullevs 34 and 35 respectively receiving and guiding the cords H and I. As already referred to, this guide is secured to the frame at substantially its middle point. The combination of this mounting of cords with the wheeled brackets moving in grooved guides is a par.- ticularly efficient apparatus. The wheels runnin in the grooves give an easily and smooth y opera-ted structure provided they are not bound or twisted in the guides. With the arrangement of cords heretofore employed with such brackets, the brackets were connected to different length of cord so that with the inevitable stretching by use, the cords were soon of different relative lengths causing tilting of the roller and binding of the wheels in the grooves. By the arrangement of cord mounting as described this disadvantage is avoided and furthermore, the placing of the guides for the bracket cords at the centre of the top of the window frame facilitates its co-operation with the holder on the window sill to which the shade cord extends.

At the bottom of each of the bracket guides is a closure comprising a plug 36 closely fitted within the channel of the guide and a rounded cap 37 which fits over the end of the channel. This closure is secured in place by a screw 38 which secures the plug to the guide or may pass through the guide into the window frame. To relieve the impact of the bracket in coming against the closure, aswhen the bracket falls or otherwise, a rubber buffer 39 is mounted in a socket in the upper end of the plug 36.

In securing the bracket guides to the window frame, screws may be passed directly through the backs of the guides intothe window frame.

The stop P on the bottom of the shade (see Figs. 11 and 12) comprises a frame 40 with ears 41 and 42 closely enframing the tapering cross section of the shade stick 43. Rivets or screws 44 secure the frame to the stick. mounted the drum having the helical grooves 46 and i7 extending in opposite directions from the centre. At the centre of the frame is a recess 48. 'When held in this recess the cord may be drawn through the holder but when released it is quickly moved to one side or the other by a groove in the drum and wedged between the drum I and the frame. The holder 0 on the window sill is of a similar construction except that it is,

adapted for attachment to the window sill instead of to the shade stick. The shadehav ing a given spread over the surface of the window may be adjusted to any desired part of the window by loosening the cord from the holder 0 and leaving it secured in the holder P while the spread of the shade may .be adjusted without disturbing the position of the shade rollerby leaving the cord secured in Q and releasing it from P.

lVithin the frame 40 is rotatably Referring to Figures 13 to 17 the channeled bracket guides 49 and 50, the same as the guides F and G of the previous figures, are secured to the outside face of the window. frame 51 by means of. adjustable sheet metal means. The means for securing the guide 49 comprises a foot 52 secured to the window frame by screws 53 and a flexible or bendable piece or car 54 riveted to the guide. Similarly the securing means for the a guide comprises a foot 55 secured to the frame by screws 56 and a bendable piece 57 riveted to the guide. By bending theears to which they are secured, the guides may be adjusted into alinement or other desired position. At the upper ends of the guides are brackets 58 and 59 carrying the cord guiding pulleys 60 and 61 whence the cords 62 and 63 from the respective shade roller supporting brackets pass to the pulleys 6 L and 65 in the frame 66 secured to the outer face of the top portion of the window. 'The cords 62 and 63 then merge into a single cord, passing down the center of the window back of the roller and shade and to cord holders on the window sill and shade stick as described in connection with the apparatus of Figurel. The adjustable shade roller supporting brackets and shade roller are of the same construction as in Figure l. v
