`Ihis invention relatesto new and usefuliimprovernents in bufling wheels* s j f "lfleijetofore it has been;` cu tomaryto buildlup buiiirig wheels updri, Ithfshaijts fof `biiiing `1`na chines `by `placingspacer'washers and `felt discs alternately in position. On `a"`rnachine requiring a` Wide `Iouifing wheel, the, time Iconsurnedfin mountin'gfthe discs and washers "in position is about three and onehalf "hours".` ,s d

' It isanobject lof` `thisinvention .to construct a` buiiingwheel` section which includes a unit of spacenwashersand `felt discs. By using these units it is possible to mount them upon the shaft of a buffng machine in `about one half hours time. d Obviously an important `advantage of `the bufling wheel unitis the saving lof time in mounting them in position on a machine. A

Moreover, present day buflingwheels built up from felt discs `and spacer washers Wear out` in a relatively short period of time.` "Ihey also1 wear outlunevenly, which is objectionable. in vention proposes the construction of abutting wheel. jwhichwill have a longerlife than present daysimilar wheels `and which` will wear outinore evenlygwhichfurther adds toitlsllife. d f," `1\`,/.[ore specifically the `i vention proposes,`to characterise the new andiinproved buifng wheel byfthefactfthat it includes annular feltsections spaced from each other and cloth faced cork sections between and spaced from the felt sections. The cork sections with the cloth facings are stiffer and more durable than the felt sections. They serve to support the felt sections and in this way prolong the life of the buing wheel. Moreover, cork material is known to be excellent for bufling. It has numerous pores which hold the grease and polish. This is desirable. I have discovered that thin cork sections were too fragile and entirely unsatisfactory. I have further discovered that thin cork sections could be used provided they were laminated with cloth. It is for this reason that they are pro vided with facings of cloth. When thus constructed they are highly durable and a far superior bufng Wheel is produced.

The invention also proposes that the felt sections and cork sections be provided with radial slots extending inwards from their peripheries and dividing oif arcuate portions to add to the flexibility of the bufiing wheel.

It is another object of this invention to secure the felt sections and the cork sections together with fastening elements to produce a unit previously referrred to. The fastening elements may comprise rivets.

, 2 j. Another,` object oflthis invention is to` provide each buiiing wheeLor unit, with a spacer element mounted on one face for spacing the rst section and last` section4 of adjacent similar units when they are mounted on `the shaft of a buing machine. d d d d ,d The invention contemplates a modiedform in which the felt and `cork sections are of different designs and constructions. j

Anotherjobiectof the invention is theconstruction of a device as described, which is sinrple and durable and which may be manufactured andsoldat a reasonable cost. I Q `Forfurther comprehension of the invention, and of `the objects and advantages thereof, referencewi11 ,be` had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are moreparticularly set forth.

Inthe accompanying drawing forming afn'iate` rial part of this ,disclosure`- Fig. 1 is a perspective View of a buling wheel constructedin accordance with this invention.

Fig. 2is a fragmentary enlargedvertical sectionalviewtaken on the line 2`-2 of Figli.

Fig. 3 is Aa fragmentary enlarged detailed view of one ofthe cork sections shown in Figs. 2.

4 is a fragmentary sectional viewjj similar to 2` `but illustrating a modified form of buff# The buing wheel, in laccordance with that form of the invention illustrated in Figs. 1 to 3 inclusive, includes annular felt sections III spaced from each other and cork sections II between and spaced from the felt sections I0. Spacing washers I2 are engaged between the sections I0 and I I for holding them in their spaced relationship. A spacing washer I2 is also mounted on the outer face of one of the end sections for spacing this section from the adjacent section of a similar `buifing wheel. Fastening elements, such as rivets I4, are engaged through the spac ing washers I2 and the sections I0 and II for holding them in a unit.

Each cork section Il comprises a central disc section I5 of cork and cloth laminations I E, or cloth facings I6 pasted or cemented together. The cloth facings I6 may comprise muslin or similar cloth material. For an eight inch bufling Wheel the felt sections III and cork sections II may be one-sixteenth inch thick. The felt sections III and cork sections II are provided with radial slits 21 extended inwards from their peripheries and diving off portions 28 so as to make the bufling wheel more flexible. In lieu of cork` ing elements, or rivets 25 engage through the flanges 24. The felt sections 20 and cork sections 2| are cemented upon the peripheral edge portions of the support members 23 and are also secured in position with lines of stitches 26. The cork sections 2| comprise ce-ntral cork portions 2. The combination in a buiilng wheel having means for holding annular sections in spaced positions, of annular felt sections spaced from each other, and cork sections between and spaced from said felt sections, said cork sections being faced with cloth facings.

3. A buiing wheel comprising annular felt sections spaced from each other, cork sections between .and spaced from said' felt sections, and

' fastening elements xedly connecting said sections together as a unit, said unit having a spacing element mounted on one face for spacing the vrst. section from the last section of an adjacent similar unit. 4. A buflng wheel, comprising annular support Y members xedly connected together in a unit, and

and cloth facings similar to the detailed disclosure shown in Fig. 3.

The operation and use of the new and improved buiiing wheel may be understood from the following:

It should be noted that the buiiing wheell comprises a unit of .disc-like sections. These units may be readily mounted on the shaft of a'buiiing machine for building up a bufing elementof any desired width. Mounting the units onvthe shaft of the bufing machine is very much faster than mounting felt discs and spacing washers, as is now the case. The new buing wheel will be more durable than present day buflng wheels because the cork sections or ber sections, will support the felt sections I0. Moreover, the cork sections make excellent buiiing sections. The pores in the cork will hold the grease and polish.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as kdeined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. vThe combination in a buiiing wheel having means for holding annular sections in spaced positions, of annular felt sections spaced from each other, and cork sections having cloth vfacings between said felt sections.

annular'felt sections and annular cork sections with cloth facings mounted upon the peripheral portions of said support members and spaced fromeach other.

"5. A bulling wheel, comprising annular support members xedly connected together in a' unit, .and annular felt sections and annular cork sections mountedupon the peripheral portions of said support. members, said cork sections being cloth faced.

6. The combination in a buing wheel, having means for holding annular sections in spaced positions, of annular ,felt sections spaced from eachother, and laminated cloth and cork sections between and spaced from said felt sections.
