CURTAIN AND ADJUSTABLE SHADE SUPPORT Filed DeC. 6, 1930 2 Sheets-Sheet 2 Inventor A llorney l embodying a Patented June 14, 1932 UNITED STATES PATENT oFFlcE FRANK A. LOVRICH, OF DAMSITE, MISSOURI CURTAIN .AND ADJUSTABLE SHADE SUPPORT Application led December 6, 1930. Serial No. 500,618.

This invention relates to a curtain and adjustable shadersupport and has for its primary object to provide, in a manner as hereinafter set forth, a device ofv this character novel construction and arrangement of parts whereby the shade and shade roller may be expeditiously adjusted vertically to any desired position relative to a window and maintained in adjusted position.

Other objects of the invention are to provide a curtain and adjustable shade support of the character described which will be simple in construction, strong, durable, attractive in appearance and which may be manufactured and installed at low cost.

All of the foregoing and still further objects and advantages of the invention may become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein vlike characters of reference designate corresponding parts throughout the several viewsfand wherein Figure 1 is a view in front elevation of an embodiment of the invention.

Figure 2 is a view in side elevation of the invention.

Figure 3 is a detail view in top of the upper brackets.

Figure 4 is a horizontal cross sectional View taken substantially on the line 4-4 of Figplan of one ure 1.

Figure 5 is a vertical sectional view through one of the lower brackets taken substantially on the line 5-5 of Figure 1.

Figure 6 is a vertical sectional vview through one of the lower brackets taken substantially o n the line 6--6 of Figure 1.

f Figure 7 Vis a horizontal lcross sectional view taken substantially on the line 7--7 of Figure 1.

Referring to the drawings in detail, it will be seen that the reference numeral 1 designates a pair of what will be hereinafter referred to as lower brackets which are provided with suitable openings for the passage of securing elements such as screws or the like for mounting said lower brackets on the lower portion of a window frame.

' the openings 11 and Each of the lower brackets 1 comprises a stationary or base portion 2 which is anchored to the window frame and which has its outer portion provided with a horizontal groove 3 for the reception of a tongue 4 formed integrally on one side of a movable section or portion 5. The tongue 4 is slidable longitudinally in the groove 3 toward and away from the window frame upon which the lower brackets are mounted. The stationary portion 2 Aof each of the brack-ets 1 is provided with a bore 6 which communicates with the groove 3 and with the socket 7 in t-he tongue 4 and the movable portion or section 5. Mounted inea-ch of the lower brackets 1 is a coil spring 8 which is disposed in the bore 6 and the socket 7 and has its ends operatively connected with vwhich are above and below the groove 3 are provided with vertically aligned openings 11 and the tongue 4 is provided with a vertically extending opening 12which is adapted to be brought into vertical alignment with the openings 11 when the movable section 5 is moved in a direction away from the stationary section 2. It may be well to here state that the coil springs 8 yieldingly pull the movable sections 5 toward the stationary sections 2 of the lower brackets 1. r1`he opening 12 is normally out of vertical alignment with the purpose of said openings 12 and 11 will be more fully hereinafter set forth.

Upper brackets designated generally by the reference numeral 13 are provided with apertured base portions 14 for securing said. upper brackets in position on the upper portion of the window frame in vertical alignment with the lower brackets 1. Each upper brackets 13 includes an integral arm portion 15 provided with openings 16 for the passage of curtain supporting rods 17. l'ach of the upper brackets 13 is provided with a recess The pin 9 1s 18 which extends upwardly thereinto from its lower side and has rotatably mounted therein a grooved pulley 19.

Vertical guide rods extend between the upper and lower brackets 13 and 1 and are supported thereby. Curtain supporting blocks 21 are slidably mounted on the guide rods 20 and have vertical openings 22 extending therethrough inwardly of the guide rods 20. The inner end ot one of the blocks 21 is provided with a channel 23 extending downwardly thereinto from its upper side for the reception ot one of the pintles on the shade roller 24 and the other of the blocks 21 has its inner end provided with a socket for the reception of the other pintle on the other end of the shade roller 24. It will thus be seen that the shade roller 24 is rotatably supported between the inner ends of the supporting blocks 21.

Suitable cables or ropes are trained over the pulley wheels 19 and extend through the openings 22 in the blocks 21 and are secured to the blocks 21 for actuating said blocks in a vertical plane by set screws or the like 26. The end portions ot the cables or ropes 25 are operable through the openings 11 and 12 in the lower bracket 1 and have secured to their ends suitable gripping handles or knobs 27.

As best seen in Figure 6 of the drawings, the cables or ropes 25 are normally frictionally clamped against movement by the tongues 4 of the movable sections 5, said movable sections 5 being actuated by the springs 8. The openings 11 and 12 are disposed on opposite sides of the springs 8. When it is desired to adjust the window shade vertically the movable sections 5 of the lower brackets 1 are moved outwardly against the tension of the coil springs 8 in a manner to release the lower port-ions of the cables or ropes 25 after which said cables or ropes may be actuated in either direction over the pulley wheels 19 to move the shade supporting blocks 21 either upwardly or downwardly on the guide rollers 20, as will be apparent. When the movable sections 5 of the lower brackets 1 are released the cables or ropes 25 are again frictionally and securely clamped against movement and the shade is thus secured in adjusted position. As seen in Figure 4 of the drawings, the guide rods 20 are of polygonal horizontal cross sec-- tion and pass through correspondingly shaped openings in the supporting blocks 21 and in this manner rotation of the blocks 21 on the guide rods 2O is prevented.

It is believed that the many advantages of a device in accordance with this invention will be readily understood, and although the preferred embodiment ot the invention is yas illustrated and described, it is to be understood that changes in the details of construction may be had which will tall within the scope of the invention as claimed.

A curtain and shade supporting structure comprising a pair of upper brackets and a pair of lower brackets attached to a window frame, a guide rod of polygonal cross section extending between each of the corresponding upper and lower brackets and supported thereon, a block mounted for vertical sliding movement on each of said guide rods each block having a polygonal opening therein for the passage et the respective guide rod for retaining the blocks againstrotation,said blocks engageable with the respective ends of a shade roller in a manner to rotatably support said shade roller therebetween, each block being further provided with a vertical opening in its intermediate portion, the upper brackets each being provided with a recess, a pulley journaled for rotation in each recess, a flexible cable trained over each pulley and having its end portions depending therefrom, one of said end portions of each cable extending through the vertical opening in each of the blocks, a set screw securing each of the blocks to one ot the cables, and means on each of the lower brackets for frictionally retaining the end portions of each of the cables against movement.
