HEEL-FINISHING MACHINE.

SPECIFICATION forming part of Letters PatentNo. 743,993, dated November 10, 1903. Application filed March 25, 1902. Serial No. 99,851. (No model.)

To all? whom it may concern:

Be it known that I ROBERT W. THOMSON, of Lynn, county of Essex, and State of Massachusetts, have invented an Improvement in' Heel-Finishing Machines, of which the following description, in connection with the accompanying drawings, is a' specification, like characters on the drawings representing like parts.

This invention has for its object the pro-' duction of an improved machine for finishing heels, said machine being constructed and arranged to apply a hard wax to the heels.

In accordance with this invention I employ any usual or suitableform of cloth wheel or cloth-covered wheel orother flexible non-inetallic work-rubbin g wheel which is constructed with a convex yielding heeLengaging rim, many such wheels being already well known, and provide means for applying wax to the heel engaging rim of said wheel and for spreading the wax thereon. Preferably the wax-spreading means is heated, so as to assist in maintaining the heel-engaging rim of said wheel at a temperature sufiiciently high to keep the wax thereon in molten condition while it is being applied tothe heel and for shaping the heel-engaging rim of said wheel.

In practice the heel is held pressed against the work-rubbing wheel with considerable pressure,and this resultsin flattening the convex rim of the wheel, which for the best results should be restored to its original shape, so that the portion of the rim acting on the heel shall always present a convex surface.

The necessity for providing means for acting on the rim of the wheel for restoring it to proper shape is rendered greater by reason of the rim becoming saturated with the is a vertical section of the machine shown in Fig. 1, taken on the dotted line 2 2.

Fig. 3 is a vertical section of the heated roll and waxapplying device shown in Fig. 2. Fig. 4 is a detail of the means shown in Fig. 2 for moving the heated roll out of engagement with the work-rubbing wheel.

In the embodiment of the invention herein shown, it represents a flexible non-metallic work-rubbing wheel or roll, which is here shown as a cloth wheel or cloth-covered wheel, and 0, represents a shaft to which the work rubbing wheel is secured.

11 represents an idle roll which is loosely mounted on a bar I) and disposed relatively to the work-rubbing wheel to bear upon its heel-engaging rim. The roll 19 has an annular recess h? in one or both of its sides, which provides for the employment of suitable gasburners 19 by means of which said. roll is heated.

form of heel-engaging rim, the heated roll 3) will be formed with a circumferential groove or recess 19 of a corresponding shape in order that it may snugly embrace the wheel.

The heated roll, shaped as described, acts on the wax-saturated rim of the work-rubbing wheel, heating said rim and molding it in accordance with the face of the heated roll, thereby efiectually restoring said rim to its original form.

The shaft or bar bearing the heated roll I) is held in suitable bearings in a movable frame, which is herein shown as comprising a pairof arms b secured to a shaft b held in suitable hearings in the frame of the machine,

The shaft b has an arm Z9 projecting from it, formed with an inclined surface which is engaged by a friction-roll b borne by a lever I7 pivoted at b, said lever extending forward within easy reach of the operator.

sition to the dotted-line position in Fig. 1

the arm 11 will be depressed and the shaft 39 correspondingly rocked and the heated roll I) moved out of engagement with the workrubbing wheel.

The lever h has secured to it a yoke,

which serves as the belt-shifting device for the belt I), which drives the pulleys 17, mounted on the shaft 0,.

The lever I3 will be moved to shift the belt onto the fast pulley at the same time that it operates to move the heated roll into engagement with the work-rubbing wheel and to shift the belt onto the loose pulley at the same time that it operates to move the heated roll out of engagement with the workrubbing wheel. It is important to remove the heated roll from engagement with the work-rubbing wheel when said wheel is at rest to prevent the heated roll injuring the wheel by standing in engagement therewith.

Beneath the heated roll I; a wax-pot c is provided which is supported by the frame, and a wax-delivering roll cl is contained in the wax-pot, projecting above the wax-pot into a position to be engaged by the heated roll I) when the heated roll is in its operative position in engagement with the work-rubbing wheel a, and as said roll (Z is turned by the heated roll I) it takes from the wax-pot and delivers to the heated roll 19 a supply of hot wax, which is transferred by said heated roll to the wheel a. When the heated roll is moved to place it out of contact with the work-rubbing wheel, it is also removed from engagement with the wax-delivering roll d, as shown in dotted lines in Fig. 2. The waxpot is heated for melting the wax in any suitable manner-as, for instance, by a gasflame, as shown in the drawings.

The wax-delivering roll at will be made very narrow, so that but a small quantity of wax will be supplied to the heated roll I).

In practice the work-rubbing Wheel a will be driven at highspeed, and the hotwax conveyed to it by the heated roll I) will be ap-- plied to the heel and rubbed over the surface of the heel.

It will be seen that the heated roll I) not only conveys heated wax to the work-rubbing wheel and spreads it over the convex surface of the cloth rim of said wheel, but it also heats the said rim, so as to soften the wax with which it is saturated and mold the rim into its normal convex shape after it has been flattened out by contact with the heel of the shoe being treated. By heating the work-rubbing wheel by means of the waxconveying roll, as described, the wax or finishing material on said rubbing-wheel is kept hot and in proper condition for the finishing operation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States 1. In a machine of the class described, a work-rubbing wheel having a yielding working surface, a roll, out of contact with the work, and shaped to embrace the working surface of said work-rubbing wheel, and means for heating said roll, whereby heat is imparted to said wheel, substantially as described.
