SHADE-SUPPORT.

Specification of Letters Patent.

Patented Sept. 9, 1913.

To all whom it may concern:

Be it known that 1, ALVA B. SMITH, a citizen of the United States, and a resident of Memphis, in the county of Shelby and State of Tennessee, have invented a new and Improved Shade-Support, of which the following is a full, clear, and exact descrip-' tion.

The object of my invention is to provide a shade support with casing members, each with two portions disposed at an angle to each other, and each portion having a vertical slot, so that bracket carriers may be concealed behind the casing members and the brackets for supporting the shades which are secured to the bracket carriers may be disposed through one set of vertical slots, and a transverse member connecting the bracket members may extend through the other set of slots. A cord mounted. on pul- Jeys is provided for adjusting and supporting the bracket carriers.

Other objects of the invention are to provide brackets on which the pulleys may be quickly and conveniently mounted, to provide means by which the cord may be held taut, and to provide convenient means by which the cord may be operated.

Still other objects of the invention will appear in the following complete specification, in which the preferred form of the invention is disclosed.

In the drawings similar characters of reference indicate corresponding parts in all the views, in which- Figure 1 is a front elevation of my invention; Fig. 2 is an enlarged transverse secti'onal elevation of Fig. 1; Fig. 3 is a frag mentary sectional view of one of the brackets at the top of the device; Fig. 4 is an en larged perspective view showing one of the studs used on the brackets shown in Fig. 3 of the drawings; Fig. 5 is a sectional view on the line 5-5 of Fig. 1; Fig. 6 is a vieW of a sprocket wheel which in connect-ion with the sprocket chain is used for operating the cord; Fig. 7 isa perspective view showing a folding crank used in connection with the sprocket wheel shown in Fig. 6 of the drawings; Fig. 8 is a sectional view showing the connection of the crank with the sprocket wheeland chain; and Fig. 9

is a view showing a modified arrangement of the pulleys and cord.

By referring to the drawings it will be seen that the brackets 10 are secured to the top 11 of the window frame 12. Each of these brackets has sides 13, with openings 14, the sides of each of these openings 14 converging toward the center of the window frame. Disposed in the openings 14 in each of the brackets 10 there is a stud 15, the studs 15 having transverse grooves 16 for receiving the edges of the brackets at the openings 14, so that the studs 15 may be disposed in the openings 14 at their widest ends, and when the sides are moved toward the center of the window frame the grooves 16 in the studs 15will fit the sides of the openings 14 to prevent the studs 15 from becoming displaced. The brackets 17 are secured at the bottom of the window frame 12, each of these brackets 17 being provided with two vertical channels 18 and 19, the terminal 20 of the stud 21 traveling in the channel 19, and the said stud 21 at its bent portion 22 traveling in the vertical channel 18. This stud 21 is bent downwardly as will be seen by referring to Fig. 2 of the drawings, and it has a threaded terminal 23, which extends through an opening 24 in the bottom 25 of the bracket. Nuts 26 are provided, these nuts meshing with the threads on the terminals 23, and pressing against the bottoms 25 of the brackets 17 for holding the studs 21 down, and the cord 27 taut, which is disposed under a pulley 28 mounted on the horizontal portion of the stud 21. The cord 27 is disposed upwardly from the right-hand bracket 17 then over the pulley 29 mounted on the stud 15 of the right-hand bracket 10, then over the pulley 29 mounted on the stud in the left-hand bracket 10, then over the pulley 28 mounted on the left-hand bracket 17, then up and around the pulley 29 on the left-hand bracket 10, coming out from under the left-hand pulley 29 and across to the underside of the right pulley 29, then around the right pulley 29 and down and under the pulley 28 mounted on the stud 21 in the right-hand bracket 17.

As will best be seen by referring to Fig. 5 of the drawings, the bracket carriers 30 are secured to the cord 27 within the casing 31, the brackets 82 extending out from the easing 31 through slots 34- in the front 33 of the casing 31. These bracket carriers 3Q are connected with the corresponding bracket carriers disposed within the casing 31 at the other side of the window, by means of transverse members 35, which extend; through slots 36 in the sides 37 of the casing. The shade roller 38 is mounted on the brackets 32.

I prefer to secure the right-hand bracket 30 to the part 39 of the cord 27, and I prefer to secure the left-hand bracket 30 to the part 40 of the cord 27, these parts 39 and; 40 being shown in Figs. 1 and 5 of the drawings.

As will be seen by referring to Fig. 8 of the drawings, a sprocket wheel 41 may be substituted for one of the pulleys 28 and a sprocket chain 42 may be provided for co operating with this sprocket wheel 41, the end of the sprocket chain 42 being secured to the ends of the cord 27, so that while the sprocket chain &2 will cooperate with the sprocket wheel 4L1 the cord 27', which is connected therewith will be disposed over the pulleys 29 and the pulleys 28' in the other bracket 17. hen this sprocket wheel is used I prefer to provide a yoke 43, having bearings 4d and 45, thestud 46 on the crank l? being disposed in the bearings 45, with the angular portion 48' of the stud d6 ex tending through the angular opening 49' in the sprocket wheel 41, and with the round terminal 50 of the stud 46. disposed in the bearing 4-4. This terminal 50 isv not only disposed; in the bearing 44, but it also ex-. tends into the vertical slot 18 in the bracket 17, and the round portion of the stud at the crank 47 is not only disposed in the bearing 45 but also extends in the vertical slot 19 in the bracket 17, and also through a slot 51 so that the crank 47 proper is disposed in the outer side of the bracket. A crank H has a portion 52 hinged at 53 so that the crank may be folded, the handle 54: extending into the recess 55 when the crank is folded as shown in 8 of the drawings.

In Fig. 9 of the drawings I show a modi fiedarran ement of the u )er ulle s and of the cord disposed therearound. In this construction two

pulleys

29 and 29 are provided at the right of the window frame, and two pulleys 29' and 29 are disposed at the left of the window frame, the rope or cord l7 extending upward and over the right pulley 29 and over and around the left pulley 29*, then under the pulley 28 then up and over the left pulley 29, then 1 across and over the right pulley 29, the cord then extending under the right pulley 28", With this construction the cord 17 is disposed in a more convenient manner to have the bracket carriers secured thereto.

To the yoke 43 is secured a threaded memopenings 2d in the bottom 25 ofthe bracket l 17, and being engaged by a nut 26, which presses against the part 25 of V the said bracket 17.

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