FRANK GUNN FARNHAM, OF HONESDJIGILE,` PENSYLVANIA.
SPECIFICATION forming part of Letters PatentNo. 709,312, dated September 16, 1902.
' Applicata mea october 28,1901. staunt. 80.280. (man.) v
To all whom it may concern: n Be it known that I, FRANK GUNN FARNHAM, a citizen of the United States, residing at Honesdale, Pennsylvania, haveinvented certain new and useful Improvements in Polishing-Wheels, of which the following is a speci- My invention relates to improvements in cleaning and polishing wheels of that nature in which cloth is used as butiing or polishing material. Thesehave generally been constructed by securing either single strips or folded strips to aesnitable hub. or support, the strips overlapping each other and radiating from the hub 'to form a disk or wheel.A
Wheels formed from single strips of fabric are not durable, as theedges ravel very rapidly on both sides and on the end, so that the lifetime of the wheel is very short. The wheel composed of folded strips is more durable, but can be run only in one direction, owing to the foldin thecloth, as if the wheel 'is turned so that the cloth progresses with Y the fold or apex backward it catches the ma- ?5 I terial operated upon in the'fold.
The object'of the present invention is to v provide a brush which will avoid these disadvantages and which will be durable and elective andwhich may be run in either direction, thu's`prolonging the life of the wheel.
I have illustrated theinventionvin the accompanying-drawings, in which-1- Figure 1 is a side@h elevation 'of a brushwheel, and: Fig. 2 is a sectional view. Fig. 3 is a detail view ofone ofthe tubes. Figs. 4,
Fig. 7 is a view of a modified form of brush.
, Referring moreI particularly to the iigures,
the wheel designated in'Fig.1is composed of a plurality cl3-radiating sections of cloth at a,`which averla-peach other `and which are securely" cemented to each other. i Their inner ends abut against the central disk b and,
if desired, at intervals disks-of cloth, paper,
or the like may be interposed,as shown at cs in Fig.y 2. Each of these cloth sections consists of a tube of seersucker or likematerial,
. which maybe eithera woven vtube or a sewed tube, as desired, and the whole 'fis strengthened by a line of stitching a. In case asewed tube is used itis preferable vto turn lthe tube inside out, so as to bring the seam outheminside, as shown in Fig. 3. Instead of usinga single tube, as shown in Figs. 1, 2, and 3, I may use cloth sec'tions of the form shown in Fig. 4, in which it will be seen that a piece of cloth is folded upon itself Vand stitched at c at a distance from 'and parallel to the edges.
This provides a tubular portion c' and two loose flaps c2. When the tube is' reversed,
stitching 22st theinner edge of theshorter one.
The projecting portion d3 of the longer one only is cemented to the adjoining parts. This gives me a very narrow hub with a heavy Working body, which is very desirable 'for many classes of work. If desired, I may place inside of each tube any kind of ber or yarn, as illustrated at e in Fig. 6. It will be understood that these wheel-sections are to ybe secured upon suitable-supports or carriers and operated in the manner described by patents of the United States granted to me April 30 and July 2, 1901, and numbered, respectively, 673,119 and 677,502. If desired, I may reinforce the tubes composing. the brush by a cloth disk B on each side, as indicated in Fig.
7, each dis-k or reinforce being composed of two circular pieces of cloth stitched together by lines of stitches, (indicated at B'.) This is advantageous in stiffening the brush for certain kinds of work. of tubular brush it is not necessary that they themin place on the sleeve. 'Brushes of this class, called textile brushes, are apt to wear beveling or hollow. When this occurs, the
operatorl can remove the sections from the .sleeve iu a moment and replace them again,
thus getting an even wear to all the edges. A brush made up from these tubes I dnd has about double the wear in it that there is in a 'brush made from similar goods, buthaving Inthis sectional. form should be nailed together, as the collars hold IOO ` comprising a. plurality of-projecting bunches,
each of said bunches comprising Y:at tube of textile material, snbstan tially 'as described'.
2. .A ring or section for a polishing or cleaning wheel consisting of a series of independent, projecting bunches,'each of said bunches consisting of a folded material sewed near its center to form a. tube and free edges, the tube being turned inside out -to bring said free edgeswithin the tube to-serve as a, filler therefor, substantially as described. Y
A ring or section for a polishing or clean- `ing wheel comprising a lplurality of tubes of textile .material secured to a suitable carrier and an independent tube secured separately romain lt..-irilragor section for a polishing-wheel comprising a plumlity of tubesof textile materaland reinforcing-disks of textile material, substantially as described. 5. A ring or section for a polishing-wheel comprising a plurality of tubes of textile material, said tubes beingstitched together, substantially las described.
6. A. 'ng or section for a polishing-wheel comprising a plurality of tubes of textile material and reinforcing-disks of double textile described.
In testimony whereof I ailx my signature in presence'jof two witnesses.
