ROTARY Bnusm A Application filed March 12, 1927. Serial No. 174,849.

My present inventiomin its broad respect, has reference to in'ipii'ovements in rotary brushes of the type defined in my prior Patent #1.,466,103 granted August '28, 1923.

.A More particularly it is my purpose to provide an improved clip device for assembling the several bunches or tufts of material com prising the brush upon the ring therefor in such a manner as to largely eliminate 1 spaces between the Several tufts orbunches, prevent loosening of the clips from the bunches or tufts, and induce agreater uniformity r compactness of the material wherewith the brush is formed. To these of a plain ring whose edges and surface are unbroken, and about which the clips are size and any number of clips may be used depending on the size of the ring. The bunches of material forming the brush are bent around the ring each upon one of the several clips, and each clip is formed with plural cooperating tongues, one of each pair of which has an eye through which the U other tongue is received and bent over to unite a positive lock to prevent displacement or looseness of the bunches of material embraced by the tongues. For the foregoing and other reasons I consider under certain circumstances that my present invention is a. valuable improvement over the structure of my prior Patent #1,466, 103 granted August 28, 1923. I i

The manner of constructing my brush, and other important advantages thereof, will be more fully apparent from the following description and drawing wherein Figure 1 is a plan view of a brush assembled in accordancewith my invention,

Figure 2 is a plan view of the blank stamping from wlnch my clip is formed,

Figure 3 is a perspective view of my clip, the various parts thereof beingshown in their approximate cooperating positions, 50 a Figure 4 is a perspective view of one of my clips applied to a ring fragment, and

Figure 5 is a transverse section through my brush.

In the drawings wherein like characters of reference are used to designate like or and other equally important ends my present invention contemplates the utilization ship so that noinde )endent movement of similar partsthroughout the several views The numeral (1) designates a flat ring (shown in dotted lines in Fig. 1), a fragment of which is shown in Fig; 4 in full lines.

- The clips, (2) 'by which the bunches or tufts of material A are held on thering, are each formed from an inte ral blank stamping shown in plan view of ig. 2, and which has two pairsiof tongues, res ectivelyi(3) and (3 and (4) and (4). Tongues (3) and (4 of each pair have eyes (5) in their free ends and said pairs of tongues are connected by -spaced web members (6). A lip (7) extendsoutwardly from the portion (8) of the blank betweenth'e tongues (3 and 3), and as shown the tongues are arcuate, the respective pairs being curved out in opposite directions. The clips (2) are assembledion the ring by bending the blank at the web members (6) to dispose the portions (8) betweenthe tongues against the respective sides or thering, The lip (7) is then bent over to attach. the clipipositively to thering. At this stage in the rocess of assembly the tongues extend out rom the sides of the ring substantially as shown in Fig. 4. The bunches or tufts of material A are now bent around the ring; each bunch or tuft upon a clip between the tongues and the ton ues are then bent or pressed down upon the unches with the ends of tongues (3) and (4) through the eyes (5) of tongues (3) and (4 The said ends of tongues (3) and (4) are then bent over to lock the tongues in position about the bunches or tufts. It will be noted that theclips are assembled as close together as possible about the ring and that the tongues of each clip bear against the tongues of the next adjacent clips so that no independent movement (or other movement for that matter) can take place between the clips circumferentially of the ring when the brush is rotated. It is not necessary to spot weld the overlapping ends of the tongues, nor is it necessary to specially form my ring (1), such as is defined in my prior patent before referred to. Furthermore there is no limitation in the size of ring that may be used or the size of the center opening therein, and the tongues can be lengthened or shortened to take care of different amounts of brush material, Fiber, wire or any other suitable material may be used in forming the brush. While in the foregoing there has been illustrated in the drawings and described in the specification such combination and arrangement, of elements as constitute the preferred embodiments of my invention, it is nevertheless desired to emphasize the fact that interpretation of the invention should only be conclusive when made in the light of the subjoined claims. 7

I claim:

1. A brush comprising a ring, a plurality of clips around said ring, said clips each having tongues projecting therefrom, certain of which are formed with eyes and the ends of the remaining tongues receivable in the eyes and bent over to retain the said ends and bunches of brush material folded around the ring and clamped by the tongues bent down thereon.

2. A brush comprising a ring, bunches of material folded around said ring, and a series of clips arranged around the ring and having oppositely extending tongues clamping said material at opposite sides of the ring, said tongues having interlocking portions to prevent disengagement of the tongues.

3. A brush comprising a ring, clips extending around the ring and having projecting tongues at opposite sides thereof, and bunches of brush material folded around said ring and clips, the tongues being bent down upon said material at opposite sides of the ring and having interlocking porends to receive the ends of the remaining tongues, and said tongues adapted to be bent down upon said bunches of material and the ends received in the eyes bent over to prevent disengagement of the tongues.

5. An article of manufacture for use in attaching brush material to a ring to form a rotary brush comprising a clip formed with pairs of arcuate tongues curved in opposite directions from a central web connecting portion, one tongue of each pair formed wlth an eye in which the other tongue is engaged, and a lip extending outwardly from between the tongues of one pair.

6. A clip to retain brush material on a ring, formed from a blank and comprising oppositely curved arcuate portions one end of each of which has an eye, an intermedia e web connecting said arcuate portions, and a lip extending from one of the arcuate portions.

In testimony whereof, I do afiix my signature.

RUDOLF R. RADINSE.
