IMIROVED MACHINE FOR IINISHING lTHE EDGE OFBOOT AND SHOE-SOLES @the Sdgcmtle nient it in tips@ trttcts ttent nu making un n f tige sans.

TO ALL WHOM IT MAY GONCERN Be it known that I, CHARLES W. PALMER, of Lynn,'in the eountyvof Essex, and State of Massachusetts, have invented an Improved Power-Machine for Finishing'the Edges of Boots and Shoes; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention suiiicient to enable those skilled in the art to practise it.

For certain classes of boots and shoes the soles are cut to form, or size and shape, by whole dies, or otherwise, so that they do not have to be trimmed or out on the edges by hand-knives by the workmen.

For finishing the edges of such soles, hand-tools have heretofore been employed to give grooved edges of any desirable conformation, and the polished surface required. The use of such-toolsrequires a great amount of muscular labor, consuming much time, and the object of my invention is to lessen the labor and time required, besides effecting the finishing of sole-edges in a superior manner.

In finishing solecdges as described, by hand, it has been generally the practice to apply the hand-to0ls to the soles after they are secured 4in place ou boots or shoes, though, more rarely, the nishing of the edg'es has been donesupon the soles before they have been fastened to the uppers.

In making use of my machine, the edges of the soles are invariably finished by it before the soles are applied to the boots or shoes of which they are to form a part.

The drawing represents an elevation of a machine embodying my invention.

a denotes a frame, having bearings at ZJ, in which a shaft, c, is made to rotate rapidly, by means of a belt applied to the pulley d, xed on the shaft between the bearings. On the end of the shaft is affixed a cylinder, preferably of metal, into which are turned grooves of a width corresponding with the thickness of the solecdges to be finished, the edges of the grooves, or the flanges on the cylinder, forming guides or gauges, which prevent any sidewise movement of the soles submitted to the action of the machine. On the bottom surfaces of these grooves may be left small ridges, which are such in number and shape as to produce in the sole-edges the grooved formation required for ornament. The sides of the grooves or the flanges are preferably mede a little flaring, so that the sole will enter the groove easily. A number of these grooved cylinders may be made to shift off and on the shaft, so that a large variety of patterns-or groovings may be impressed on the edges of soles of various thicknesses.A

The finishing-operation is improved by heating the cylinder, which may be done by a ilame appliedbeneath, the workman applying the soles to the upper part of the cylinder, rarely using that part which is below a horizontal plane passing through its centre. The lcylinder may be made hollow, and steam may be introduced for the purpose of heating it.

The workman holds a solo in his hands, andintroduces it into the groove, which is of a width corresponding to the thickness of thc sole, and then, pressing the sole upon the rapidly-revolving cylinder, moves the sole so that all portions of Vits edge receive the frictional Contact offthc bottom surface of the groove, by whiehthe edge is smoothed, polished, and grooved, if grooving is required, and if the beads or illets'are made on'the bottom surface of the groeve.

On the other end of theshaft is shown a modification of my invention. Thev cylinder there shown is not formed with flanges; only the growing-fillets or heads are made on the cylinder, if desired.

The gauges or guides are made separate from the cylinder, and attached to the frame by means of screws, the screw-holes in the gauges being slotted, so that the gauges can be adjusted toward or from cach other to tit Aany thickness of sole. A

I claim, for the purpose of nishing the edges of detatched soles, the machine constructed and operating 'substantially as described.

CIIAS. W. PALMER.
