SPECIFICATION forming part of LettersPatent No. 270,294, dated January 9, 183.

Application filed March 20, 1882. (No model.)

.To all whom z't may concern i Be it known that I, SIGMUND FEUsT, of the city, county, and State of New York, have invented certain new and usefulImprovements 5 in Bufflng and Polishing Machines, of which the following is aspecilication.

The object of this invention is to furnish a bnfing and polishing machine for articles of brass or other metal, which is easily and safely ro worked and constructed in such a manner that `the shaft carrying the buffing'material can be adjusted in downward direction as the material wears off, and in which the heads which retain the buffing material can be conveniently removed and reduced in size Without taking the bufiing material from the shaft.

My invention consists in the combination, with the buffng-wheel and the shaft-carrying the same', ot' separable heads,lwhich can be detached rfrom the' shaft and reduced so as to correspond to the size of the bufling material as it wears oll without 'removing the latter from the shaft, the bufiing material being divided by intermediate disks into a number of z5 separate sections, all as hereinafter described and claimed.-

In the accompanying drawings, Figure '1 represents a side elevation of my improved buffing and polishing machine. Fig. 2 is a plan with a part broken o. Fig. 3 is a vertical transverse Section; Fig. 4, a vertical longitudinal section; Fig. 5, a top View of-the mechanism forimparting lateral motion to the feed-table; and Figs. 6, 7, 8, 9, 10, and 11 are details.

Similar letters of reference indicate correepondigg parts.

Referring to the drawings, A represents the supporting-frame of my improved buing and polishing machine, which supports on side standards, A', the bufng-shaft B, that is revolved byv a belt-and-pulley transmission from a suitable counter-shaft.

Below the buffng material is arranged a 45 feed-table, C, to which longitudinal reciprocating motion and,.simultaneously therewith,

lateral motion isimparted. The reciprocating' motion is imparted either by hand or power. In the former case the feed-table is turned in 5o one direction or back by means of a handwheel, a, keyed to a transverse shaft, c'. For

this purpose a pawl, b, has first to be released from a ratchet, b', on the shaft c' by means of a treadle, d, and connecting-rod d'. The pawl b serves to lock the feed-table into rigid posi- 55. tion, so as to prevent any accidental motion of the same when the same is not in use.

The feed-table G consists of alower section, C', which is provided at the under side with racks-@that mesh with pinions e' of the drivingshaft c', the section C being guided by means oftapering side rails,f, 011 correspondingly grooved Ways, f', of the supportingframe A.

Upon transverse ways tofthe lower section, C', is guided the upper section, C2, ofthe feedtable, which section receives lateral motion from a wave-wheel, g, the shaft g of which `is rotated by any suitable transmitting mechanism from the driving-shaft a'. The Wave- 70 Vw heel g engages an anti-friction roller, gofa fixed arm, g3, applied to a frame, g4, which latter is guidi-d in lateral openings of frame A. The frame g4 carries upright arms g5., having anti-friction rollersgsattheir upper ends, which 75 latter engage parallel rails hat the center and under side ofthe upper section, UZ. Simultaneously with'the forward motion of the leedtable, which is imparted by the pinons and racks ofthe lower section, the upper section is laterally reciproeated by the mechanism described, or any equivalent thereof, so as to eX pose thereby the work applied to the feed-table to the action of the bnfling wheel or brush D and prevent it from getting streaky. 8

The Work to be polished is secured to the upper section of thefeed-tableC in any approved manner. When the feed-table C has arrived at its extreme position in one direction the motion ofthe driving-shaft is reversed, and there- 9o by the feed-table returned in opposite direction, so that the goods are passed va second Vtime below the buffng-wheel, and 'so on alternately. The heffing-wheel D is inclosed by a guard easing. or hood, D', which is provided 95 with a hopper at the top, through which the buliing compound is slowly supplied to the bufling-wheel or cylinder. `The hoodl DI4 prevents vthe throwing of the dust toward the operator, so as to protect the same. The standroo ards A', which carry the bearings of the shaft of the hurting-wheel, areadjusted in inclined length of the driving-belt ot' the butting-shaft need not be changed, even when the buftingshaft has to be lowered or raised, owing to the wear of the buftlng material or the replacing of new material. The inclined standards A are slotted and provided with clamp-nuts 4,so

4as to be rigidly secured after the bufting-shal't has been adjusted to the propel' relative position on theI feed-table C.

The buffing-wheel D is supported'on the bufiing-shatt B by means ot' separable and detachable heads D2,which arescrewed up against the bnt'ling material by a washer, m, and set and jam `nuts m', as shown clearly in Fig.' 7. The separable heads D? are made of sections u, of quadrantal or semicircular shape, which are screwed to supporting disks or collars n', asshown in Fig. 11; or they are made of interlocking sections n, applied to supportingdisks n', as shown in Figs. 9 and l0, so that by slightly loosening the washer m and unscrewing the connecting-disks u the sections a of the heads D2 may be separated from each other and removed from the shalt, so as to be reduced in size, without removing the bufting material from the shaft. In this manner the heads of the bufng material can always loe kept at a size which corresponds exactly to that of the but'ting material, notwithstanding thegrad-- `nal reduction which takes place in the size of the same by wear. By means of intermediate separating-disks, 0', made of metal,the buflug wheel or brush D is divided into a number of sections, as shown in Fig. 7, which is of certain advantage in the buffing operation.

Thev buiing wheel, drum, or headv may be composed offelt or other suitable fabric or material, or these wheels may be composed of a combination o t' materials suitably adapted to the purpose. I make no claim to the material of which the wheels are made, as any of the well-known buftng materials may be adopted.

The head D2 of Fig. 8 is formed of two semicircular plates, n fn, secured to similar plates, n', which break joints with the joints of the plates n. The head D2 of Figs. 9 and 10 is formed of two angular interlocking plates, a n, Screwed to a disk, n. The head shown by Fig. 10is composed of segment-rings u,screwed to a disk, fn, onthe shaft B. l

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a bufling and polishing machine, the combination, with the buftingshaft carrying the bufug material, of separable and removable heads for retaining the same, and means, substantially as described, for securing the heads to the butting material, substantially as set forth.

2. In a buffi-ng and polishing machine, a baiting-wheel composed of movable and detachable sections, with disks of smaller diamter interposed at intervals, and heads pressed against the outer sections, all clamped to gether on the shaft,substantially as described. 3. The combination of an adjustable buling `wheel or brush, a feed-table composed of a lower reciprocating section, C', an upper lat.

erally-reciprocating section, C2, a laterally-reciprocating frame, g4, provided with upright arms, the rollers on these arms traversing be tween rails h, tixed to the bottom of the sec- SIGMUND FEUS'I.
