Another "object v"of this invnt'ionis to produce a buiiing Wheel section in the f'o'rr'n of a 'simple one piecesheet metal Vstamping which directly supports the fabric bung portion and at the same time serves a's a rigi'dfcentering disc for the wheel. y 1
Inthe drawings: my A* Fig. 1 isl aface view of one of the buiing sctions of the wheel.
Fig). 2 is a sectional view through the buiiin'g section taken along line 2-2 of Fig; 1.
,Fig 3 is a partial Viewy on an enlarged scale A'ofjtlhe cross-sectionshown in Fig'l 2;

y Fig. 7 is a view illustrating the assembly of the fabric buiiing section to the metal disc center.
Fig. 8 is a fragmentary perspective showing my bung section.
Referring to the drawings it will be seen that the wheel is made up of a plurality of individual buiiing wheel sections I each of which comprises a round centering disc II having a fabric bufng portion or ring I2 secured around the periphery thereof. Disc II is preferably formed as a one piece metal stamping which is slotted radially around Aits periphery as at I3. The successive slotted portions are struck out alternately 'at each side of the disc so as to form two sets of offset lugs I4 which extend outwardly from the body portion I of the disc in a lateral and radial direction. The -oifset lugs I4 define a circumferential groove I6 around the outer edge of disc II. The body l5 of disc I I is Lprovided with a 2 flanged central aperture 'II which receives the spindle I9 of'a polishing lathe.
The -buiiing portion I2 of the Wheel is formed -'from a continuous strip .of bias cut `fabric in a manner well known in this art. The fabric strip is `first vrolled lengthwise into a spirally wound hollow 'cylinder and then a wire I9 or other suitable fastening band is positioned over and around the spirally `Wound strip'. The fabric cylinder is now folded radially outwardly with respect to the Wire ring I9 tofform the ybuflf 'section I2, vas shown inthe drawings. AAs shown `in Fig. '7, at this time the right handset of lugs I4 extend at a right angle to disc I I and the left hand 'set of lugs extend at about 1a 45 angle thereto'. The fabric. bufffsecft'ion I2 and ring I9 'are now slipped bver the disc II so Vthat Wire 'ring I9 is substantially in the plane of disc II and thereafter the lugs Mare pressed radially outwardly and toward eachother to thereby clamp theinner e'dge of fabri'cbuii, section I2 and wire I9 to the metal disc I I. vThe fabric forms a multi-layer bufling ring I2 with the inner annular edge 20 held rmly in the groove I6 by 'ring I9 and lugs rI4 'and the edges. ofthe `fabric form the peripheral face of thewheel. A
It will be Aobserved .that the 'lugs I4 vat one side of disc I I are` spaced from and staggered or offset relative to `the lugs I4 on ,the 'other side of the disc. The buffing portion I2 is therefore retained firmly on the disc :b'oth bya clinching action on the part of thesev vlugs and also by the binding action 'of band I9. Sincethe Yinner edge 29 of -b'uling ring I2 is gathered;I this portion ofthe ring is quite thick and the thickened portions bulge out at each side of the disc in the spaces between successive lugs as shown at 26 which serves to prevent the fabric bufng ring I2 from slipping around the disc II even though it is not firmly clinched by lugs I4.
When it is desired to build up a plurality of these buiiing sections I 0 into a bulng wheel. a number of sections corresponding to the width of wheel desired are mounted on the spindle I8 of a polishing lathe, the central anged apertures I'I serving to center each section on the spindle. Sections I0 at each end of the wheel are backed by end plates 2| which may be drawn together by means of a nut 22 threaded at the end of spindle I8. The outer face of most of the lugs I4 are provided with hemispherical depressions 23 while three or four lugs I4 at each side of the Wheel are formed with hemispherical projections 24 which interengage in the depressions 23 on the lugs of the adjacent disc when the sections are nested together so that all the sections ID are keyed together and rotate as a unit.
I claim:
1. A bufling wheel comprising a plurality of cloth layers folded into an annular buiiing ring with the fold defining the inner edge of said ring, a rigid centering disc supporting the inner edge of said buf'ring ring, said centering disc having a central aperture for receiving a spindle and having its outer edge radially slitted to form a plurality of lugs around the periphery of said disc, the successive lugs being alternately offset, one lug on one side and the next lug on the other side of the plane of said disc to dene a groove for the folded inner edge of said bufng ring, the successive lugs at each side of saidV wheel being spaced apart, and a ring member enclosed within the fold of said fabric layers and clamping the inner edge of said bufiing ring in said groove, said inner folded edge of said buing ring having a thickness greater than the width of said groove whereby the portion of said cloth between successive lugs on each side of said wheel bulges outwardly beyond the plane of said lugs and prevents said centering disc from rotating relative to said bufing ring, and including means formed on the outer face of said lugs for keying said disc with the lugs of a similar disc when a plurality of said discs are arranged adjacently on a spindle.
2. I'he combination as set forth in claim 1 wherein said keying means comprise indentations on the outer face of some of said lugs and projections on the outer face of others of said lugs, whereby a plurality of said disc may be arranged to rotate as a unit on a spindle by arranging said discs so that the projections on the lugs of one disc engage with the indentations on the lugs of the adjacent disc.
3. A buing wheel comprising a strip of fabric wound spirally and folded circumferentially into an annular buiimg ring, the outer edges of said fabric strip forming the peripheral face of said buing ring and the folded edge defining the inner edge of said ring, a sheet metal centering disc directly supporting the inner edge of said bufng ring, said centering disc having a central aperture for receiving a spindle, the outer edge of said disc being formed into a plurality of laterally offset lugs, said lugs being spaced alternately at each side of said disc to form a peripheral channel therebetween, said folded edge being disposed within said channel and engaging said alternately offset lugs on opposite sides thereof, and a ring member enclosed Within the folded edge of said buing ring and binding said folded edge in the channel formed by said lugs, the successive lugs being spaced apart in a direction transversely of the plane of said disc a distance less than the thickness of said folded edge, and including means on the outer face of at least a portion of said lugs adapted to engage lugs of a similar disc when a plurality of said discs are arranged on a spindle so that all of said discs rotate as a unit.
4. A buffing wheel comprising a plurality of bufng sections arranged adjacent one another on a spindle, each section comprising a plurality of fabric layers folded into an annular bufng ring, the folded edge of said fabric layers forming the inner peripheral edge of said bufng ring, a rigid centering disc supporting said buffing ring at said inner peripheral edge, said centering disc having a central aperture for receiving a spindle and being formed with a plurality of laterally offset lugs around its outer periphery, said lugs being disposed alternately around said disc on the opposite sides thereof to form a peripheral channel around the outer edge of said disc, said folded edge being disposed within said channel with the fabric engaging said lugs, and a ring member enclosed within said folded edge and clamping the inner peripheral edge of said bui'ling ring in said channel, said channel having a rwidth lessthan the thickness of said inner folded edge whereby the fabric between successive lugs at each side of said disc extends outwardly beyond the plane of said lugs, and including means formed on the outer face of said lugs for interengaging similar means on the lugs of an adjacent similar disc to lock said disc together so that they will rotate as a unit when a pair of discs are arranged on a spindle with the lugs on one disc face to face with the lugs on the other disc.
