' SHADE ROLLER Filed Dec. 5, 1934 v INVENTOR ATTORN EYS Patented Dec. 24, 1935 UNITED STATES PATENT oFFIcE l SHADE ROLLER s John Fehan, Kenmore, N.-Y.

Application. December v5, 1934,#Seral No. 756,157 4 claims; (o1. 15e- 36) 'I'his invention relates to shade rollers, an 0bject of the invention being to provide a shade roller which is capable of adjustment so that the bottom of the shade may be adjusted to the desired level without changing the tension of the spring-roller or re-setting the shade cloth on the roller.

In the prior art it has been the custom to mount the shade rollers in the conventional brackets which are mounted at a predetermined place on the window casing. It has been known that when shades are so mounted on a plurality of windows, positioned closely one to another, it is impossible to have the shades arranged at a common level. This act of artistry has been a besetting problem to the shade industry for a long time. The only available means of arranging several shades at a common level has been to remove the shade cloth from the roller and to mount it on said roller in a different position. This has been diflicult, tedious, likely to damage shade cloth, and not lead to certain results and an alternative expedient and one that is even less satisfactory is to remount the brackets on the window casings at a higher or lower level. Obviously, this involves a defacement of window casings and in most cases has not been permissible. Accordingly, in spite of an insistent demand for a means for mounting a plurality of shades on windows positioned near each other so that the shades stand at a common level, no means as heretofore mentioned have been available.

My invention resides in means for making it possible to mount a plurality of window shades on a yseries of windows so that they can be brought readily to a common level. My invention permits the attainment of this objective without, on the other hand, hazarding the damage to the shade cloth by altering its position on the roller and without, on the other hand, risking the defacing the window casing;

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, all of which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawing,-

Figure 1 is a broken perspective view illustrating my improved shade roller;

Figure 2 is an enlarged view in longitudinal section through one end of the roller;

Figure 3 is a view in transverse section on the line 3/3 of Figure 2;

Figure 4 isa view in transverse section on the line 4/4 of Figure 2; and

Figure 5 is a view in sectional elevation of the spring washer.

I represents the wooden barrel of the shade 5 roller having a longitudinal bore 2 at one end toaccommodate a spring 3. In the particular illustration of the invention kone end of the spring is secured to an anchor 4 xed in the inner end of the bore 2 and a wooden core piece 5 is located 10 within the spring, but it is to be understood that the invention is not limited to the specific form illustrated but is capable of a wide modication to accomplish the desired result.

6 represents a spindle which is connected to the 16 spring 2 and projects beyond the end of the barrel and, as is customary, the roller is provided at the opposite end with a pin or round trunnion 1. A ratchet disk 8 is secured to the end of the barrel and has a central opening 9 to accom- 20 modate the spindle 6. The ldisk 8 may have prongs or spurs I0 struck therefrom and driven into the end of the barrel I, and in its outer face is provided with a circular series of serrations or teeth Il constituting a ratchet rack. 25

I 2 represents a pawl -plate having a central opening I3 to accommodate the spindle 6, and this pawl plate is provided with teeth or projections I4 which engage the ratchet' teeth II of the disk 8. The plate I3 carries pawls I5 which 30 engage a notched enlargement I6 on the spindle 6 and a spring washer I1 bears against the pawl plate so as tohold the teeth thereof in engagement with the rack Il. An ornamental ferrule I8 is located over the disk assemblage and over 35 the end of the wooden barrel, and may have its inner end deflected inwardly engaging the wooden barrel so as to hold the assemblage on the barrel, and. it is understood that the spring washer II is disposed between the end of the ferrule I8 and 40 the pawl plate I2 and exerts suicient power to hold the pawl plate against turning movement relative to the roller until such force is applied as will overcome the spring. It also is to be understood that the pawl plate is frictionally or 45 otherwise held by the ferrule so that when the ferrule is held and the wooden barrel turned there will be an adjustment of the pawl plate relative to the disk II as the teeth I4 will move on the ratchet rack, and this enables the roller 50 to be adjusted so as to adjust the bottom of the shade cloth I9 which is secured to the roller.

While I have illustrated what I believe to be the preferred embodiment of my invention, it is to be distinctly understood that various slight 55 changes may be made with regard to the form and arrangement of parts without departing from K my invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope ofV the claims. Y Y

I claim:

1. The combination with a spring shade roller, of a ratchet disk secured Vto the end of the shade roller, a spindle projecting through the disk, a notched member on the spindle, and a pawl carrying assemblage mounted to turn on the end of the roller and having teeth engaging the ratchet disk. Y

2. The combination with a spring shade roller, of a ratchet disk secured to the end oi the shade roller, a spindle projecting through the disk, a notched member on the spindle, a pawl carrying assemblage mounted to turn on the end of the roller and having teeth engaging Ythe ratchet disk,

and a spring washer in the assemblage exerting pressure thereon holding the teeth in operative engagement with the ratchet teeth.

3. The combination with a spring shade roller, of a ratchet diskl secured to the end of the shade 5 roller, a spindle projecting through therdisk, a notched member on the spindle, a pawl plate, teeth on the pawl plate engaging the ratchet disk, pawls on said pawl plate engaging the notched member, a ferrule mounted to turn on the roller 10 and enclosing said disks, and a spring washer L interposed between the ferrule and the pawl plate and exerting pressure on the latter to normally maintain the teeth in engagement with the ratchet disk. l5 4. 'I'he combination with a spring roller',V a rotatively adjustable pawl carrying plate at the end of the roller, and means controlling rotary adjustment of the pawl carrying plate relative to the roller. 20
