To all whom it may concern.'

Beit known that I, WILLIAM A. PAINTER, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Buffing or Polishing Wheels, of which the following is a specification.

In the -accompanying drawings, which illustrate applications of my invention, Figure 1 is a part side elevational and a part sectional view of a buffmg or olishing-wheel embodying my invention; ig. 2 l a detail view showing a piece of folded cloth turned back to particularly illustrate the manner of assembling the folded pieces; Fig. 3 a vertical Sectional view of a wheel built of full sized pieces as shown in Fig. 2; Fig. 4 a sectional -iilamentous or exible material, such asl view of a modified form of wheel showing a wooden hub; Fig. 5 a side view of a wheel with outside disks omitted showing folded and overlapping full sized disk-pieces Fig. 6 a vertical sectional view showing a modified form ofcompleted wheel Fig. 7 a broken detail view illustrating a different method of assembling the folded pieces from that shown by Fig. 2 Fig. 8 a lan of a strip of material from which the fol ed pieces may be formed; Figs. 9 and 10 detail views indicating the manner of folding rectangular pieces; Fig. 11 a detail view of a waste piece from a large disk and Figs. 12, 13 and 14 detail views of a disk and illustrating the manner -the disks are folded.

An object of my invention is to provide a new and improved buffing or polishingwheel made `of cloth or other textile fabric,

muslin, cotton-cloth, canvas or felt.

Further objects of the present invention are to rovide a wheel of substantially the same tfiickness throughout, a wheel simple to assemble and operate, and a 4wheel ossessing more durable wearing qualities t an wheels of this class as heretofore constructed.

Referring to thev drawings 1-1 designate circular pieces of cloth or other suitable material of a size that it is desired to forma wheel, as shown by Fig. 1, I employ three disk-pieces 1, two being outside pieces and one a centrally disposed piece. Located between said pieces 1 are a plurality of radially folded pieces 2. These pieces 2 form a characteristic and important feature of the present invention. from a circular piece of cloth or other mate- The larger or open ends The pieces 2 may be formed v rial such as indicated by Fig. 12 or the piece may be formed from a rectangular piece as shown by Figs. 8, 9 and 10, or a square piece of material may be em loyed from which said pieces are folded. he pieces 2 are folded radially from the center or other point.

of the pieces constitute the periphery of the wheel and the smaller ends are nearer the center of the wheel thereby forming, when the pieces are assembled as shown, radial lines in proportion to the circumference wheel and at the same time wheel of uniform thickness. may be assembled by placing the same over, against or between each other. Fig. 2 illustrates the radially fold d pieces overlapping and placed between th foldsof one another and Fig. 7 shows the pieces laid one upon another. l

The prime object of the fold is to produce a cross-cutting or diagonal surface on the cloth or other material employed, in different directions. ing each other as described and illustrated, prevents the material from pulling out or fraying on the working or exposed edges of the pieces.

Another important feature of the folded pieces isthat pockets are formed adapted to receive and hold a bufiing composition, such as rouge or other compound employed in buiiing or polishing.

Wheels of this class as heretofore constructed have been built up of strips, pieces or disks superposed parallel to one another with the raw edges exposed, consequently the threads of the fabric pull out quickly and the life of the wheel is comparatively short. Under my method of folding and assembling the threads are not pulled out and the whee will wear much longer than wheels built up as above described.

` By my invention, I am enabled to employ what has heretofore been waste material, that is to say, commercial bufiing wheels have heretofore been made of disks of from eight to eighteen inches in diameter, these wheels soon, wear down to a diameter too small to be used and the centers or remaining portions of the wheels while being of a diameter from say, four to eight inches are discarded.

In Fig. l, I have shown a'form of wheel constructed of used or discarded pieces 2.

producing a The pieces The mesh of the fabric crossy In assembling a Wheel of this form a circular vpiece 1 of the diameter the completed wheel 1sv to assume is employed. This is then spread out flat and the scrap disk-pieces 2 folded radially as shown, preferably two folds, valthough one fold or more than two folds may be given the piece, `and the folded -mediate di'sk.

,My invention is not limited to a folded piece as described made from a circular or I disk-piece 2, for I may employ pieces 2 of the form of Fig. 9, or pieces of votherfrms than p those shown. Nor do I limit the present invention to a wheel built up of used or discarded folded pieces, for it is equally within the scope of my invention to employ new full sized pieces as shown in the forms of Figs. 8, 5 and 6. When new pieces araemployed said pieces are folded radially and assembled in substantially the same manner as heretofore described.

In Figs. 3, 4 and 6 I have shown modified forms of wheels mounted on a spindle 4 of a buflinv or polishing machine.

In the form of Fig. 3, I show a wheel made from full size new disks, said disks being held together between two metallic plates 5 and pins 6 extending through said disks and plates. l

The form of Fig. 4 shows a wooden hub 7 with the small radially folded piecessecured thereto and held between two metallic plates similar to the plates shown by Fig. 3.

In the form of Fig. 6 I employ very thin metal disks or plates 5a. In this form of wheel I have shown a thin metal disk 5b in the center of the wheel. is provided with spurs 5C.

What I claim is:

1. A bufhng or polishing-wheel comprising a plurality of radially folded overlapping pieces and means for securing the pieces together.

2. A bufiing or polishing-wheel having a a plurality of radially folded pieces.

3. A buing or polishing-wheel having a plurality of radially folded overlapping pieces. A buffing or polishing-wheel having a hub portion and an outer portion formed by a plurality ofradially folded pieces.

Each of these disks 5. A bufring or polishing-wheel com rising u outer disk-pieces, a plurality of radial y folded pieces interposed between the outer pieces, and means for securing the said folded pieces to the disk-pieces.

6. A built-up bufiing or polishingwheel comprising outer pieces, a plurality of radially folded overlapping pieces interposed between the outer pieces, and means for securing the said folded pieces to the outer pieces.

In testimony whereof I affix-my signature in presence of two witnesses.
