UNITED STATES PATENT OFFICE. R JAMES D. PERROTT, OF BEAVER FALLS, PENNSYLVANIA. ADJUSTABLE WINDOW-SHADE FIXTURE.

Specification of Letters Patent. Application filed May 18, 1907.

To allwhom it may concern: I

Be it known that I, JAMES D. Pnnno'r'r, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, and useful Adjustable WVindow-Shade Fixture, of which the following is a specification.

The invention relates to improvements in adjustable window shade fixtures.

The object of the present invention is to improve the construction of adjustable window shade fixtures, and to provide a simple, inexpensive and efficient one, adapted to permit a window shade to be raised and lowcred bodily to arrange it over any desired portion of a window, and to provide light and ventilation above the window shade.

A further object of the invention is to provide an adjustable window shade fixture, adapted to afiord rigid supports for the window shade, when the same is arranged at the top of the window.

Another object of the invention is to provide an adjustable window shade fixture, adapted to permit the unrolled portion of the window shade to be arranged in praccords, without materially afiecting the vertical posit-ion of the spring journal, whereby the latter will always be maintained in proper position to be engaged by the ratchet device for holding the shade roller station- I ary.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully l described, illustrated in the accompanying j I l drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the inj vention.

In the drawings Figure 1 is an elevation of an adjustable window shade fixture, I constructed in accordance with this inven tion and shown applied to a window. Fig. i 2 is a side view, showing the supporting member of the spring journaled in engagement with the cooperating side casing. Fig. 3 is a similar view, showing the supportin member out of engagement with the side i bracket. Fig. a is a detail view of the side 1 have invented a new i casing, which cooperates with the supporting member of the spring journal. F 5 1s a detail sectional view on the line a -zr of Fig. at. Fig. 6 is a side elevation of the other side pulley and the other supporting member. Fig. 7 is a perspective view of the side casing shown in Fig. 6. Fig. 8 is a detail sectional View on the line g y of Fig. 6. Fig. 9 is a detail perspective view of the double pulley or sheave and the means for clamping the operating cord. Fig. 10 is a vertical sectional view of the same. Fig. 11 is a detail sectional view of the spring actuated cam for engaging the operating cord.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 and 2 designate supporting members, whlch receive journals 3 and 4 of actuated shade roller 5 of a window curtain or shade 6. The supporting member 1, which consists of a narrow strip of metal, is provided at its lower end with a clamp, consisting of a vertical portion 7 of the supporting member and a clamping plate 8, which is connected with the supporting member by adjusting screws 9. The vertical lower portion 7 of the supporting member is arranged in parallelism with the clamping plate 8, and the two members of the clamp are adapted to receive between them the flattened portion of the spring journal 3, which is firmly held by the clamp. The supporting member is provided with an inclined intermediate portion 10 and has a quarter turn or bend thereat to arrange the upper portion 11 in a vertical plane at rightangles to the vertical plane of the lower portion 7. The inclined portion 10 off-sets the lower portion 7 of the supporting member 1 from the window or casing 12, when the window shade or curtain is at the top of the window, as hereinafter more fully explained. The other supporting member 2, which is also constructed of a narrow strip or piece of metal, consists of an inclined lower portion 13 and a vertical upper portion 14. The lower end of the supporting member 2 is provided with a perforation 15, forming a bearing opening for the reception of the pivot or journal 4 of the shade roller. The pivot or journal l preferably consists of a screw, but any other suitable means may be employed for connecting one end of the shade roller to the member 2.

The upper portions are provided at inter mediate points with

perforations

16 and 17 for the reception of adjusting cords 18 and 19, which pass over

guide pulleys

20 and 21 of side casings 22 and 23. The side casing 22 is provided with front and rear side plates 2a and 25, and it is open at one side to form a recess 26 for the reception of the upper portion of the supporting member 1. It is provided within the recess with vertical shoulders 27, formed by plates 01' pieces 28 arranged within the casing, as clearly illustrated in Fig. 4 of the drawings, but the shoulders may be constructed in any other preferred manner. The front and rear plates or pieces are spaced apart by means of sleeves 29, arranged on rivets, or other suitable fastening devices, which connect the plates. The guide pulley 20 is mounted on a suitable pivot or spindle, arranged in bearing openings or perforations of the front and back of the side casing 22. The supporting member 1 is provided at the upper portion with a rounded edge 31 for guiding it into the recess 26, and the lower edge 32 of the front plate is bent outward at the bottom of the recess to form a flaring entrance to the same. The upward movement of the supporting member 1 in the recess is limited by a hookshaped lug or projection 33, located at the outer edge of the supporting member 1 at the lower end of the upper vertical portion of the same. The adjusting cord, when drawn taut, is adapted to hold the support ing member 1 firmly interlocked with the side casing 22 in the position illustrated in Fig. 2 of the drawing. This will maintain the window shade in spaced relation with the window frame, and the window shade will then be supported as firmly as an ordinary window shade having fixed bearing brackets.

The side casing 23 is provided with

plates

34 and 35 and it has interiorly arranged shoulders 36, formed by inner plates 37. The plates are spaced apart by sleeves 38, and the bracket 23 is provided at one side with a recess 39 to receive the upper portion of the supporting member 2. The upper end of the supporting member 2 is provided with a rounded or curved edge 10, and the lower edge 41 of the plate 35 is curved outward to provide a flaring entrance to the recess of the side bracket 23. The side member 2 is also provided at the lower end of the upper portion with a projecting substantially hookshaped lug 42 to interlock with the outwardly curved edge of the plate 35, whereby the supporting member 2 is firmly held in engagement with the casing 23, when the adjusting cords are placed under tension with the supporting member 2 in engagement with the casing. The guide pulley 21 is mounted on a pivot 43 and is arranged on the plates 3 1 and 35, and a second guide pulley 14, which receives the adjusting cord 18, is mounted on the pivot 43 between the plate 35 and a plate 45. The plate &5 is spaced from the plate 35 by suitable sleeves 4E6, disposed on the rivets or fastening de- Vices, which also connect the plates 3 1.and 35.

When the adjusting cords are operated to lower the window shade or curtain, the supporting members 1 and 2 drop out of engagement with the side casings 22 and 23, and the unrolled portion of the window shade will then he in substantially the same plane as the supporting cords, and this inward or backward movement of the lower portion of the supporting member 1 does not materially affect the arrangement of the spring journal with relation to the ratchet device of the spring actuated roller, so that the spring journal will always be in proper position to be engaged by the ratchet mechanism of the roller. The intermediate portions of the supporting members form a fulcrum on which the members are adapted to rock, and when the members are lowered out of engagement with the casing, the lower portions swing inwardly and the upper portions swing outwardly, as clearly illustrated in Fig. 3 of the drawings.

The adjusting cords 18 and 19 extend from the side casing 23 to a pulley or sheave &7, having a peripheral groove 18 and mounted within a supporting frame 19. A smaller pulley 50 having a peripheral-groove 51 is suitably fixed to the pulley 17, and the

pulleys

17 and 50 are mounted on a horizontal spindle, which is preferably in the form of a bolt, as illustrated in Fig. 9 of the drawings. An operating cord 52 is arranged on the smaller pulley 50 in position to wind up the adjusting cords 18 and 19 on the pulley 17, as it is unwound from the smaller pulley 50. The weight of the window shade is sufficient to unwind the adjusting cords 18 and 19 from the large pulley 47, when the operating cord is slackened for this purpose. As the small pulley 50 is approximately one half the diameter of the large pulley 17, the operating cord will move one half the distance of the adjusting cords.

The supporting frame 49, which may be mounted on the window frame or casing at any suitable point, is preferably located at the top thereof and is provided at the bottom with a horizontal extension 53, carrying a vertical plate or operating cord 52 is clamped by a spring actuated cam or lever 55. The lever 55, which is arranged at an inclination, extends downwardly from the outer end of the extension 53 of the supporting frame, and it is provided at its lower end with a substantially semi-circular head, having a notch or serrated edge and forming a cam for engaging the operating cord 52. The locking lever 55 is maintained normally in engagement with the operating cord by means of a spring jaw 54:, against which the 1 56, consisting of upper and lower loops and intermediate spring coils, which are mounted on the pivot 57 of the locking lever 55. The operating cord is adapted ,to be drawn outward away from the plate or jaw 5a, and the weight of the window shade is sutficient to overcome the force of the spring 56, so that when the operating cord is held out ward in such position, it may be released slowly to lower the window shade to the desired elevation. Any other form of locking device may be employed for holding the op erating cord.
