`l. L. G. CORNELL ROTARY BRUSH Filed May 29, 1924 WITNESSES Patented Dec. 22, 1925.
IRSIL L. G. CORNELL, 0F MILWAUKEE, WISCONSIN,
AssIGNon. To THE MILWAUKEE BRUSH MANUFACTURING COMPANY, OF MILWAUKEE, WISCONSIN, A CORPORA- TION OF WISCONSIN.
ROTARY BRUSH.
Application med may 2s, 1924.l serial No. 716,429.
To all whom it may concern.'
Be it known that I, IRsIL L. G. CORNELL, a citizen of the United States, and resident of Milwaukee, in the'county of Milwaukee and State of Wisconsin, have invented new and useful Improvemenets in Rotary Brushes, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.
The invention relates'to rotary brushes. An object of the invention is to provide a rotary brush of simple construction in which the bristles are firmly held against displacement in all directions. v
Another object of the invention is to provide certain improvements over the rotary brush shown in my United States Letters Patent No. 1,497 ,974, granted June 17, 1924.
The invention further consists `in the several features hereinafter set forth and more particularly defined by claims 4at the conclusion hereof.
In the drawings, Fig. 1 1s an elevation view of a device embodying the invention, parts being broken away and parts being shown in section;
Fig. 2 is a section taken on the line 2-2 of Fig. 1; and.
Fig. 3 is an expanded view of the hub. The hub of the brush comprises a centrally disposed bristle-receiving spider 12, and end clamping plates 13.
The spider 12 is a stamping made from sheet metal consisting of a rlng provided with a series of spaced openings 14 disposed near its outer edge and tongues 15 projecting from the inner edge of the openings, one set of tongues extending laterally on one side of the ring and another set extending laterally on the other side of the ring. Bunches of bristles 16 are. connected to the spider by passing them .through the openings 14 and bending them to extend outwardly from the arcuate portions 17 formed by cutting oripunching out -the openings 14. The brush herein shown is provided with wire bristles although the bristles may be of other material lif desired.
Each clamping plate 13 is a metal stampthe. spider toA- prevent ing providedwith a set of openihgs 18 positioned to admit passageof one set of the tongues 15 through it, and when the bristles have been placed on the spider, they are firmly clamped tov-and between it and the plates 13 .by paing the tongues through the openings 18, and crim ing their ends down upon the outer sides o the plates.
The lates 1 3 are somewhat larger than the-spi e-r 12 and-each is provided near its outer'edge with a set of laterally projecting tongues 19 punchedv out to extend inwardly adjacent similar tongues on the other plate when the hub is assembled. The tongues 19 then form partitions for each set of bristles so thatthere will be no displacement of the bristles in the plane of rotation of the brush. The clampmg plates being larger than the spider will prevent lateral displacement of the bristles so that the?7 will be maintained in their proper radial exendipg position during the life ofy the rus 'zov
A central bushing for the lbrush is formedy of bearing metal 20 which is permitted `to flow in between the plates and spider, as shown in Fig. so as to lfirmly anchor it to the hub. 'The metal fills all unoccupied place between the plas and s jacnt the bristlesto revent t eir displacement at their inner en s.- f
ider and adl The invention provides a' rotary brush of simple'construction in which the bristles are firmly secured against displacement 1nv all directions.
What I claim as new and desire to secure by Letters Patent is: p
1. In a rotary brush, the combination of a spider having a series of bristle receiving" openings near its outer ed e, bristles Vpassed through said openings an 'extending back on themselves and voutwardly in substantially radial position, tongues on said spider extending laterally therefrom, against which the outer ends of said tongues are bent to clamp the bristlesbetween the plates and against the spider, and. tongues on said plates extending laterally inwardly in adjacent relation beyond the outer edge of displacement of said plates bristles in the plane of rotation of the brush.V
2. In a rotary brush, the combination of a spider having a series of bristle-receiving openings near its outer edge, bristles passed through said openings and extending back on themselves and outwardly in substantially radial position, plates secured to the said spider at each sideand clamping the bristles between them and the spider, and tongues on said plates extending inwardly 10 beyond the outer edge of the spider to prevent displacement of said bristles in the plane of rotation of the brush.
In testimony whereof Iaftx Inysignat-ure.
IRSIL L`. G. CORNELL.
