IMPROVED BURNISHING-MACHINE.

Specification forming part of Letters Patent NO. 52,336. (lated January 30, 1866.

To all whom it may concern:

Be it known that I, NATHAN O. STOW, of Stoneham, in the county of Middlesex and State of Massachusetts, have Invented a Machine for Burnishing the Edges of Shoe-Soles, which I call a Shoe-Edge-Burnishing` Machine; 77 and I do hereby declare that the following,I is a full and exact description thereof, reference bein g had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in constructing a machine composed of a conical wheel whose surface is composed of fillets and beads alternately, as shown at F in all' the i figures, each fillet and its adjoining bead makinp,` a complete iron 77 for burnishing' and a shoe-holder in which the shoe to be operated upon is fastened. The whole, when operated, will burnish the edge of a shoe-sole as well as it could befdone by hand and much more rapidly.

To enable others skilled in the art to make w and use my invention, I will proceed to describe its construction and use.

In the drawings, Figure l is a perspective View of the machine. Fig. 2 is a plan of the machine. :Figz 3 is'a- Vertical section of the machine.

A in all the fignres represents the base or iioor upon which the machine stands. B in all the fig'ures represents the body or frame of the machine. G and G' are standards, the upper ends of which form bearings in which the shaft U of the burnishing-wheelruns. Upon the shaftU is affixed at one end the balance-wheel H, at the other end the burnishing'-wheel I`, and at about the middle the driving-pulley P.

The burnishing-wheel F in all the fig'ures is made of any suitable metal. Its exact shape is shown in section at F in Fig. 3. Its outer surface is eomposed of fillets f f' f f', &c., and of beads b b' b b', &c., alternately, as shown at F, F1' g. 3. Afillet and head combined make an iron. Thus I call that part of the burnishing-wheel that lies between the dotted lines 8 t and a v, Fig. 3, an iron. The irons are of different dimensions to suit the different kinds of shoes. The edge of a thick shoesole would be burnished .on the iron whose fillet and bead are represented by f and b,Fig. 3, while the edge of a thin shoe-sole would be burnished on the iron whose fillet and bead are represented by f` and b, Fig'. 3.

To the standard G is attached a lamp, N, which serves when burning to keep the burnishing-wheel F at the proper temperature. i

The shoe S to be operated upon is held in position by a device which I call a holder;7 and which consists of a standard, O, provided with a foot, R, Fig. 3, movable in a socket in the lever I, and also movable in the direction of its length in the standard-piece O,in which it-is held. in any desired position by the setscrew T. The lever I is operated by the foot to raise or lower the holder. M forms a fulcrum for the lever I.

Attached to the standard O is a fixed arm, X, Figs. l and 3, and a movable arm or lever, E. The fixed arm X, together with the link and block O, form an arrangement for holding in any desired position the lever E. The lever E pivots upon the pin Z, Fig. 3.

To the lever E, by means of the link n, is attached a sliding rest, D and D', Figs. l and 2, and D' and K in Fig. 8. This sliding rest moves with the lever E and assists to hold the shoe S. The end ot' the lever E is rounded off, as shown by V, Fig. 3, in such a manner as to admit of its ent-rance into the holes usually made in shoe-lasts. The shoe being operated upon is indicated by S, and the last by L.

The operation of the machine is this: The lamp N is lighted and the burnishing-Wheel set in motion. A shoe before it is taken from the last is placed upon the end V of the lever E and adjusted to the proper inclination by raising' or lowering the lever E by means of the link and block O. When this adjustment is complete the operator takes a firm grasp, one hand upon the lever E and fixed arm X and the other hand upon the shoe, and, placing it in proper position under the burnishin g- Wheel F, he puts his foot upon the lever I and thus brings the shoe up under and against that part of the burnishing-wheel which fits the shoe under operation. As the edge in immediate contact is finished the shoe is moved along and guided by the operator nut-il the entire edge has passed under the burnishingwheel.

What I elaim as my ivention, and desire to secure by Letters Patent, is-- l. A rotatingburnishng-wheel formed substantally as desoribed, and for the purpose set forth.

2. The shoe-holder made substantially as descrbed, and for the purpose set forth.
