YPSILANTI, MICHIGAN SHADE ROLLER Application filed. June 23,

The present invention relates generally to shade rollers, and aims to provide a construction which is more positive and uniform in action than those in present day use.

In carrying out the invention, we provide a novel construction of means, including a sliding pawl, which is positive in operation to check slow rotation of the roller, and yet permit fast rotation of the roller, so that under the influence of its spring, the roller can berotated in the proper direction to raise or elevate the shade.

Another object of the invention resides in the manner of mounting the spring of the I roller, to provide for both simplicity and rigidity in the construction, and to protect the spring and its associated parts from dust and other foreign matter.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and where- Figure 1 is a view in elevation and partly in section.

Figure 9 is a similar view ofthe bearing for the ratchet member.

Figure 10 is a fragmentary longitudinal section of a wooden roller.

Figure 11 is an enlarged elevation of the rod supporting disk shown in Figure 10.

Referring to the drawings in detail, 10 represents a hollow shade roller, preferably formed from metal and having its edges joined together by a suitable lock seam 11 disposed within the roller as shown. The opposed ends of the roller are closed by

flanged caps

12 and 13 respectively, the former supporting the usual pintle 14 while the latter has a circular opening 15 for a purpose 50 to be hereinafter described.

Arranged centrally within the roller 10 is a stationary hollow rod 16, supported at one end by a disk 17 having a boss 18 projecting therefrom and rotatably received by the adjacent end of the rod 16. The disk 17 is notched as at 19 to receive the lock seam 11 of the roller, by reason ofwhich construction the disk is rotated with the roller as will be readily understood. Stamped from this 7 disk 17 are tongues 20 to which the coil spring 21 is attached. 7 One end of the spring'is slipped over one of the tongues as shown in Figure 5, while the adjacent convolution of the spring is positioned between the disk and tongues as illustrated in Figure 6. The opposite end of the rod is provided with opposed

longitudinal slots

22 and 23, the latter being relatively short and opening at one end of the rod.

A flat bracket arm 24 is received by the hollow rod 16, and formed with an oflset intermediate portion 25 which projects through the slot 22- of the rod, and provided with an opening 26 through which the adjacent end of 55 the spring is passed and secured to said arm. Depending from the lower edge of the bracket arm is a lug 27 received by the slot 23. The outer end of the bracket arm projects beyond the adjacent end of the roller, and

passes through the opening of the cap 13. This end of the bracket arm together with the pintle 14 serves to support the roller on window shade brackets of ordinary well known construction. Also projecting from the opposed longitudinal eges of the arm are lugs 28 disposed within the roller inwardly of the cap 13.

Supported on the bracket arm and located at opposite sides of the lugs 28 between the latter and the adjacent end of the rod 16 and the adjacent cap 13 are bearing disks 29, each having a slot 30 to receive the bracket arm as shown. These bearings disks are each formed with a reduced portion forming an annular bearing surface 31, and

this portion of the outer disk is journaled in the opening 15 of cap 13. A ratchet-like member 32 is j ournaled on the inner disk 29, and this member 32 is in the nature of a cap having a central opening to accommodate the bearing surface 31 of said inner disk as shown in Figure 2. Carried by the cap 32 1s a flange 33 secured in any suitable manner to the adjacent end of the roller 10. Consequently the ratchet member 32 rotates with the roller and about the bearing surface 31. The ratchet member 32 is provided with opposed openings 34 to cooperate with a sliding pawl 35. This pawl is slotted as at 36 to receive the bracket arm, and the slot is of a length to accommodate the lugs 28 thereon.

The pawl is formed with diametrically opposed projections 37 adapted to be alternately received by the openings 34, and it is by reason of this construction that the roller can be positively checked while being slowly rotated, and at the same time, permit the roller to be more rapidly rotated without any interference by the pawl. Manifestly, the action of the pawl is not only positive, but uniform, while the spring is rigidly mounted and protected from dust and other foreign matter, together with its associated parts. I

The present winding unit can be used with wooden rollers as illustrated in Figures 10 and 11. As shown, the wooden roller, 1005 has an axial bore 40 at one end to receive the hollow rod 16a and spring 21a, the rod 16a being supported by "a disk 17a having prongs 41 adapted to be driven into the roller at the inner end of said bore. Otherwise, the construction of the winding unit will be the same for both metal and wooden rollers.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily understood, we desire to have it known that we do not limit ourselves to what is herein illustratedor described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What we claim asnew is: 1. A hollow spring wound shade roller, a hollow stationary rod arranged centrally therein and having a longitudinal slot, a disk mounted on one end of said rod and rotated with said roller, a bracket arm received by said rod and projecting beyond the adjacent end of the roller, said arm including an offset intermediate portion projecting through the slot in said rod, a spring encircling said rod and having its ends connected with the offset portion of the arm and disk respectively, and pawl and ratchet means for the roller.

2. A hollow spring wound shade roller, a hollow centrally located stationary rod therein having a longitudinal slot, a disk mounted on one end of the rod and rotated with said roller, a bracket arm received by end of the roller, said arm including an offset intermediate portion projecting through said slot, a spring encircling said rod and having its ends connected with the ofiset portion of the arm and disk respectively, and a pawl and ratchet means supported by said arm and within said roller.

3. A hollow spring wound shade roller, a hollow centrally located stationary rod therein having a longitudinal slot, a disk mounted on one end of the rod and rotated with said roller, abracket arm received by said rod and projecting beyond the adjacent end of the roller, said arm including an offset intermediate portion projecting through said slot, a spring encircling said rod and having its ends connected with the offset portion of the arm and'disk respectively, a ratchet member mounted for rotation with the roller and about said arm, and a cooperating pawl slidably supported on said arm.

4. A hollow spring wound shade roller, a hollow centrally located stationary rod therein having a longitudinal slot, a disk mounted on one end of the rod and rotated with said roller, a bracket arm received by said rod and projecting beyond the adjacent end of the roller, said arm including an offset intermediate portion projecting through said slot, a spring encircling said rod and having its ends connected with the otfset portion of the arm and disk respectively, a slotted disk-like bearing supported on said arm,

a ratchet member carried by the roller and rotatable on said bearing, and a sliding pawl suported on the arm and cooperating with said ratchet.

5. A hollow spring wound shade roller, a. hollow centrally located stationary rod there-" arm and disk respectively, lugs projecting.

from the opposed longitudinal edges of the tures.
