ne inkl-)own that-'1, CHARLES L. APPEL, of

" Muscatine,in theeounty-of Muscatine and @tate of' Iowa, lhave invented certain new and usefullmprovements in Button-Grinding Machines; and I hereby declare that thefollowingis afull, clear, and exact description there-"- of,ife'ferenc'e'being had: to the accompanying drawings, which form' partl of this specification.' This invention isy an improved machine-for grinding buttons to auniform thickness, and

' isfespecially designed for use in the manu.

` accompanying drawings, in which-y facture of bone and pearl or shell buttons.

It cons'istsi-n the'novel construction and combination of parts hereinafter fully de' scribed',fandsubstantiallyasillustrated in the Figurey l' vis a side elevation, partly in 'section, of` "the machine. Fig. 2 is -a top plan view thereof. Fig. 3 is a detail enlarged transverse sectiononline 3 3, Fig. l. Fig', et is a side elevation off'a modified arrangement of the machine.

In said drawings, Adesignates a support-- vertical sleeve B', in' which is journaled a` vertical shaft C, supported by a collar C', fixed thereto above sleeve B', and another collar()2 -below thevv sleeve prevents any vertical play of shaft C. These collars are adjustable, so that the shaft C can be adj-usted vertically in the sleeve. On thelower enfd of shaft C is suitable material, such as e-mery,and on the upper end of said shaft-is a grooved pulley c, tv hich is driven by a belt c' from a pulley on a horizontal shaft E, journaled on the top of support A. This shaft may be driven in any :suitable manner.

. able supports, and below the top ofthe table 5o and in frontef standard A is -a similar wheel h, journaled on a shaft H. Over said wheels ixed a horizontal abrading-disk D of any so that its motion will be positive, Isaidbelt ing or slott in the top of table T. The upper part of belt I travels'in a guideway J ,which ,extends from wheel H. up to and preferably g h runs an endless carrier-belt I of auysuit-g able construction, preferably a sprocketibelt,

past wheel g, passing close to disk D, so that brought into positionv tobe acted upon-:by

ground down to a uniform thikness.-A The Power can be applied to either'shaft-G or mover.

`If desired, a numberof these grinding-mai-- l. chinos may be mounted upon the same-table on the standard, or shaft C in the sleeve B',

or the shaft G in its bearings, er any or all these, as isobvious.

side, the shafts E. .G H being commonthe button-blanks lfed up by the belt are:

,'disk D, and being passed thereunderl are'l F65 machine can operate atv great speed, and 'the`y vthickness of the button can be varied byad- "justigle' distance"betweenV disk D and top of belt I orguide J.

H and to shaft E from any suitable 'prime l As shown in Fig.v 4, the arm B? is rigid on the standard, and the'latter is placed behind.

wheel g, the disk D, however, being held substantially vinthe same relation todis'k-wheel g.

The end of guideway J may extend to the edge of or slightly beyond the disk. D, so as te discharge'the ground buttonsjto one' side ci wheel g out of the way. The buttonsmay be fed lonto the 'belt byhand.

The guideway J is sec'urelyfasteued at its receiving end to' a projection onthe table. near the wheel h and is made of sheet-.metal or other suitable material, itsV upper en d J2'l being bent so as to lie parallel with'the face of disk D, and thus cause theV bel t or chairr to travel horizontally under the disk or parallel with the face thereof, so that the lgmttoilf'. vblanks will be ground'acc'urately.

l The carrierrnay be either-a Vbelt orgsprocketchain, preferablyithelatter, and is providedl with any suitable' button :retainingldeviees which will cause the button-blanks to move with the belt and be properly presented to the grinding-disk l).

Having thus described my invention, what I therefore claim as new,and desire to secure by Let-ters Patent thereon, is-' 1. In a machine forgrinding pearl buttons, the combination ot a horizontal disk, vertiically-adjustable supports for said disk, and means for rotating it; witha vertically-disposed and upwardly-inelinedemlless buttonearrier located below and extending beneath and to one side of the disk, adapted to carry button-blanks placed on its upper side to, under and against thel disk, part ot' said carrier directly under the disk being arranged parallel with the surface of said disk, substantially as and for the purpose described'.

2. In almtton-grinding machine, thc combination of a feed-table, a standard thereon,

an arm attached to said standard having a Vsleeve on its outer end, a vertically-adjustal)le""sliaft j ournaled in said sleeve, means for rotating said shaft, anda horizontally-disposed abrading-disk secured on the lowerend of said shaft; with an endless lmtton-earrier extending from the table to the disk, the supporting-wheels for said carrier respectively loca-ted below the table and disk, said carrier being adapted to carry buttons from the table to 'the disk, tor thepurpose and substantially as described. f

3.' AIn a button-grinding machine, the combination ofthe table, a horizontal abradingdisk attached to the lower end of a vertical shaft journaled in the support attached to said standard, a wheel below said disk, a wheel belowthe table, an endlessupwardlyinelined button-carrier ruiming over said wheels, a guide for the upper vportion of said carrier adapted to assist in guiding and retaining button-blanks thereon, said guide having its upper end extending parallel with the lower surta-ee of the disk, and means for rotating said disk and said wheels, substantially as described.

l. In a button-grinding machine, the combination of an endless carrier, and a grindingdisk rotating inaplaueatrghtaugles tothe plane of the carrier and adapted to operate upon the button-blanks 'as they are moved thereunder by the carrier and a guideway for the upper portion of said carrier extending under said disk, for the purpose and substantially as described.

5. In a button-grimling machine, the eombinaton of the table, the standard mounted thereon, the adjustable arm attached to said standard having a sleeve on its outer end; and a vertical shaft; mounted in said sleeve, and means t'or rotating said shaft; with a horizontal abrading-disk seen red on the lower end of said shaft, a wheel below the disk, awheel below the top ol` table, an endless earriersupported by said wheelsand a guide extending along the upper part/of said earrer from the table to the disk, all substantially as and for the purpose described.

In testimony that l claim the foregoing as my own l atlix my signature in prt-sence ot' two witnesses.
