To all whom iii-may concern: V

Be knownthat I, JOHN F. J ESSEMAN, of Lynn, 1n the county. of Essex and State of Massachusetts, have invented certain new and useful Improvements in Bufli'ng- Machmes, of which the following is a specification. p

' This invention relates to buffing machines; and'its object is to provide a machine of-this character with a plurality of buffin rolls adapted toperformwork of different c hara'c ters rigidly supported so that yielding or springing of one end of the roll is impossible and mounted in such a manner with relation to each other that a shoe or other article to be acted upon by the bufling-rolls maybe moved from cngagementwith one to engagement with the'other by a simple movement l in avertical plane without necessitating a tors position.

, 3 represents a vertical section on line 3 3 of Fig. 2.

The same reference characters indicate the same parts m all the'hgures.

The machine comprises a pair of. vertical frames a a, whichare mounted at a suitable distance apart andconnected by a cross-barb and shafts c d of the buffing-rolls and driving shaft c. Shafts a (Z are horizontally arranged between the frames and extend from side to side of the machine; their opposite ends being supported without possibility of yielding in rigid bearingsf g, respectively, mounted on thefframes. On these shafts areiixed buliingrolls It i, whiclnarc cylindrical in form and are placedTover the shafts so as to be rigidly supported thereby throu hout their whole extent, each end of the rolTs being so p ported with equal rigidity. and 3, the shaft c and roll it, carried by it, are supported above and forward of the shaft g and roll i, while the rolls are mounted on the shafts in corresponding lateral relations, so,

that the two rolls are located; at the same distance from one of the side frames--that is,

the rolls are arranged in the samevertical' zone-and as they are seen in iront elevation appear to be'arranged with one vertically As is evident from Figs. 2

above the other. They are also quite close together as compared with their distance from the base of the machine, above which they are held at not greatly unequal distances, one roll being about at the level of the breast ofthe operator, while theother is slightly higher. f

The shafts cpl are drivenindependently,

from the driving-shaft e by pulleys j k, the

and pulley m' on shaft 0, while pulley 7c drives shaft d through a similar belt a and pulley 0 Fast and loosepulleys p p are arranged on the driving-shaft for receiving a belt by which said shaft may be driven. I

r is an air trunk or duct which has inlet openings 8 t adjacent the bull'ing-rolls and fan-casing a, in which is located a fan connected t'o and drivenby shaft 6. As the fan revolves it expels air from the outlet c of the famcasing and draws in the air through duct 1" and openings 8 t, thereby sucking in and action of the buffing-rolls.

The rolls are abrasive materia and are preferably adapted .for performing. different kinds of workfor instance, the roll i having a rougher covering in the tread-surfaces of heels, while the roll the arrangement of the rolls is the most convenient possible for rapid work, for the operhold the shoe with its sole in contact with the heel in engagement with roll *i by a single simple movement of the hands downward and rearward without requiring any altera 'tion in the position of his body or manner of holding the shoe. Of course the order of operations may be reversed and work other than. shoes operated upon by the rolls.

ranged out of line and also laterally displaced from each other with respect to a vertical plane. "Rolls of this character also have chines are incapable of performing the best character of work inthe minimumof time, since theyeither necessitate some loss of time and energyon the part of the operator by his stepping from one to the other or cause the work to be done in a less perfect manner by carrying of]? the dust caused by the abrading h is adapted for soles. It will be seen that first of which drives shaft 0 through belt Z which extend downwardand opens into a i provided with coverings of than that of roll h and being adapted for butfator standing in front of the machine can roll it as long as required and can then place 10o Previous to my invention bufling-machines have been made with. a plurality of rolls arbeen supported only at one end. Such ma- IIO reason of insecurity of the gi'asp of the opera tor on the workin cases Wherehe does not Such rolls also are not sufficiently ri 'd, as

the end which is free will spring an yield when any pressure is put upon it. cultyis' overcome b my construction, in

ported in bearings at both ends. I claim 1. A buffing-machine comprising a pair of v side frames, and a pair of arallel rotatable abrasive bufling rolls rigi ly' supported at their'opposite ends by said frames, said rolls being arranged in the same vertical zone, one of them being above and forward of the other, and both being a considerable distance above the base of the machine and adjacent each other.

2. A buffing-machine compris' a pair of vertical side frames, a pair of orizontal shafts journaled rigidly in bearings in s id frames and extending across the space etween them, one of said shafts being above and forward of the other, and cyhndrical buffing-rolls rigidly sup orted by said shafts respectively between t e frames, both rolls being arranged in the same verticalzone, and one of them being adapted foroperating on the heel and the other on the sole of a-shoe.

A bufiing-machine comprisin a pair of vertical side frames, a pair of iOI'IZOIltftl shafts journaled in said frames and extendin across the space between them, one of said shafts being above and forward of the other, cylindrical abrasive bufiing-rolls rigidly supported by said shafts respectively between t e frames, both rolls being arranged in the same vertical zone, and one of them being adapted for operating on the heel-and the other on the sole of a shoe, an air-duct having inlet-openings adjacent said rolis, and means for exhausting air from said duct.
