SHADE ROLLER.

Application ledNovember 13, 1924.v Serial No. 749,611.

To all whom t may concern Be it known that I, VALDEMAR JOHANsEN, a citizen of Denmark, and resident of Brooklyn, in the county'of Kings and State of New York, have invented certain new and useful Improvements in Shade Rollers, of which the following is a specification.

This invention relates to shade rollers. The object of the invention is to provide a shade roller having a plurality of individual shades arranged to be operated at an angle to the longitudinal axis of the shade roller. The advantageof such a shade rolleris that the shades may be let down and operated to shade whatever objects are to be protected, and at the same time, the shade strips may be turned to permit the objects to be seen through the open spaces between the shade strips. The invention may alsobe embodied in stage curtain or side wings.

With the above objects in view, my inven tion is embodied in a shade roller constructed and arranged as hereinafter set forth and is illustrated in the accompanying drawing in which- Fig. 1 is a view of a shade roller embody ing my invention with parts in section and parts broken away.

Fig. 2 is a sectional view on line 2-2 of Figure 1.4

Fig. 3 is a diagrammatic top plan view illustrating the principle of the invention.

Referring to the drawing the reference numeral 4 denotes a tube or hollow roller of required length. The roller is preferably made of very thin or light material such as tin, aluminum or the like.

Into each end of the tube 4 there is tted a head 5 having a shaft or stud 6 whereby the shade roller is journaled in suitable bearings 7, 8 suitably attached to the frames 9 of a window or opening.

As seen in Figure 2, the tube 4 does not form a complete or perfect cylinder. The bottom portion of the tube is bent inward to form flanges 10, 10 to which is secured a base plate 11 which extends throughout the length of the tube.

The shade roller may have as many shade strips as may be desired. I have illustrated a shade roller carrying three shades 12, 13 and .14 by way of example.

Each shade strip is provided with a top member or rod 15 and a bottom weight member 16. Each shade strip is suspended from a hanger 17 pivoted in the base plate 11 and which carries avpinion 18 withinthe tube. Inside the latter there `is located a shade operating shaft 19 journaled in suit able bearings 20, 20. The shaft 19 carries bevel gears 21 which mesh with the pinions 18.

The shaft 19 is operated by means of a bevel gear 22 which meshes with a pinion 23. The shaft 24 of the latter carries a clutch member 25 adapted toV be coupled to a clutch member 26 onda shaft 27. The latter is supported in the shade bracket 7 and below the bracket there is provided a universal joint 28 to which 'an actuating shaft or rod 29`is secured. The clutch members 25 26 are kept in engagement by a spring 30 which bears against a collar or flange 31 on the shaft 27. A sleeve 32 may surround the spring to prevent it from dirt and dam* age.

Suitably spaced on the shade roller and between each shade strip there are secured to the roller suitable guiding flanges 33, 33. At one end the shade roller carries a sprocket wheel 34 operable by a chain 35.

As seen in Figure 1, the shades are unrolled and hang straight down from the roller. If it is now desired to turn the shade strip at an angle such for instance as is illustrated in Figure 3, the operator takes hold of the rod 29 and turns the same, thereby rotating the pinion 23, hence turns the gear 22 and the shaft 19. Thus all the gears 21 are rotated, which in turn rotate the pin* ions 18 and hangers 17 to adjust the shades to the desired angle. Before rolling the shades up, they are again turned back to parallel position with the roller axis.

The shades may then be rolled up by rotating the tube 4 through operation of the chain 35 and sprocket wheel 34 as is obvious. A reverse movement unrolls the shades.

rIhe shades are guided during the unrolling and rolling up operations by the flanges 33. The length to which the shades are unrolled is determined by and adjusted by the operation of the chain 35.

While the shades are being unrolled or rolled up, the clutch 25-*26 must of course be unclutched, and this may be done by pulling down the rod 29 against the force of the spring 30, until a stop 40 on said rod is brought below and set against a bracket 41 aflixed to the wall. The bracket 41 is forked to permitjthe rody to be disengaged therefrom. When the shades arey unrolled, the stop 40 is moved out from under the bracket 41:1. and; the Spring .30 vther ,automatically clutches theshafts 27 and 2i together. Y Y

The universal joint 28 is desirable because it permits the operator to stand awaj"v 'from the shade roller while operating it.k

It will be seen that my' inventi'onprovides' a shade roller comprising a plurality of individual shade strips' which may be unrolled and again rolled up like an ordinary shade or roller curtain; j

In addition the sha'defs'tri-ps may be adjiisted` in parallel rin angular relation to the a'xisy of the shade roller, sons to provideth'e required shade, yet permit objects behind thelshfa'de t0 be seen. j y j While I have disolosed `my invention in its preferred form, nevertheless, I do not desire tobe limited to ythe yexact details shown, as changesvor modiications may readilygbe made in the detailed construction without departing from the principle of th'ev invention or the scope of the appended claims.

I claim:r-- j j i j l; The Combinationofsup rting brackets, a hollow roller mounted therein anplu-y rality of shades pivoted tosaid roller, means within the roller for adjusting said shades in angular lrelation to the roller, operating in, a lplurality of shades pivoted to said roller, gearing mechanism within the roller for moving said shades into angular rela# tion with' said roller,I mechanisml for actuating said gearingI nielitnifsni at will and a sprocketand chainy for operating" said roller to lraise and lofwe'r the said shades;

3; The' eombinat'ionv of supporting means, a hollow ,roller mounted to rotate therein, al of shade'sfpiivotaflly connected to said roller, gearing mechanism within the roller for rotating said'sliade's on' their pivotal connections,pfmeans for rotating said roller .to raise and lower the said shades and a device adapted 'to bejc'lntched tsaid gear ing mechanism to operate the latter after the 'shades have been lowered and yadapted to be uncliitched from vsaid gearing mechanism preparatory to th'e raising of the said shades.
