Application filed November 23, 1929, Serial No. 409,371; and in Great Britain December 15, 1928.

This invention relates to finishing tools and is herein illustrated as embodied in a tool for finishing surfaces of heels.

It is a general practice of shoemaking in finishing heels to burnish that curved surface between the tread and attaching faces thereof at the sides ancl rear portion, which is herein termed the peripheral face, and also that exposed surface of the heel portion of a shoe forming a boundary of the rand crease as well as to impart a. series of indentations in a line parallel with the rand crease about the peripheral face of the heel. I

So far as applicant is aware, it has been necessary in the past to submit a heel to be thus treated to two separate operations which have been accomplished by the use of a tool primarily for performing the burnishing operation and another for performing the indenting operation. Although some tools used heretofore for indenting heels have been provided with a guide adapted to engage the lower rand crease bounding face and iincidentally serving as a means for burnishing it and other tools have been constructed to burnish simultaneously both this face and the peripheral face, no attempt to combine the indenting feature in a. heel burnishing tool such as that disclosecl herein has met with success prior to applicants invention.

It is, therefore, an object of this invention to provide an improved finishing tool for burnishing the peripheral face of a heel and having means for indenting it, both of which operations are clone upon a single transfer of the point of contact of the tool and the heel thereabout. In accordance with this object of the invention and in accordance with one feature thereof, the illustrated tool is provided with a burnishing surface adapted for engagement with the peripheral face of a heel along a transverse section and an indenting wheel mounted at one side of said tool whereby as a heel is progressively presented to the tool the indenting is effected on a previously burnished surfacef By presenting the Work in tangential relation to both the burnishing surface and the indenting tool, different portions of the work are both burnished and indented simultaneously, the indenting means operating on successive portions of the work which have been burnished and which are progressively presented to the tools, thereby insuring that the peripheral face of the heel shall be completelyl burnished and indented with one passage of the point of operation of the tool on the heel thereabout.

In accordance with another feature of the invention, the illustrated indenting .means comprises a wheel which is rotatably mounted and arranged to protrude from the adjoining burnishing element and, being at one side thereof, a heel may be presented in normal relation to either the indenting means or to the burnishing element at one side thereof if it is desired to utilize the tool in only one of its capacities.`

In accordance with another feature of the invention, a lipl arranged to extend from the tool at one extremity of its burnishing surface is shaped for engagement within the rand crease of a shoe in order to serve as a guiding means for the tool and to provide a surface for burnishing the lower rand crease bounding face. It will now be apparent that the illustrated tool is constructed for complete engagement with the heel portion of a shoe heightwise thereof along any transverse section, and vthat the entire exposed portion of the side and rear faces of the heel may be finished with one transfer of the point of contact of the tool and the work thereabout.

v In the accompanying drawing,

i Fig. 1 is a side elevation showing a, tool in which the invention is embodied in operative relation to a. shoe; i

Fig. 2 is a plan View of the tool and shoe as illustrated in Fig. 1;

Fig. 3 is an end elevation of the tool shown in Fig. 1; and

Fig. 4 is a fragmentary plan view of the tool with parts removed and broken away.

The illustrated tool comprises a body 10 from one end of which extends a shank 12 which is adapted for engagement within a corresponding recess in the head of a burnishing machine, which head may be vibrated to operate the tool, as indicated by the arrows in Fig. 2, or maybe held stationary as desired. VThe outer end of the'tool body 10 is convexly rounded and polished to provide a burnishing surfaceliwh-ich is-shaped for engagement :withthe peripheral .f-aceof -a heel to be operated on. As herein shown, vertical elements of this surface are substantially straight, making it particularly well adapted'for. operating on heels .ofv menis shoes, but it should be understood that this burnishing surface may be constructedt in accordance with the shape of anyheel to be operated on without departing'from the spirit of'this' invention. A lip 16 extending fromtheupper portion of the tool body 10, as illustrate'd in Fig. 1, has a burnishing surface' 18 angularly disposedwith respect to the surface 14 and is adapted 4for engagement within lthe rand crease of the shoeto be operated on iand to burnishV the surface of the heel portion' thereof forming thelower boundary of `the rand crease as wellas to provideia guide forthe burnishing` tool.

The toollbody 10 is slottecl"longitudinally thereof in its central portion as 'at"20 to receiveanindenting heel 22 which is Varranged to protrude beyond the peripheralface of the burnishing surface 14 of the toolA body. 'The illustrated indenting wheel 22 lis -rotatably mounted toward one side of the tool bodyto facilitate the presentation of the work either simultaneously or alternately to the burnishing and indenting means, as indicatedA in Fig. 2, on a stud 24 firmly fixed to a plate 26 which may be 'adj ustably secured to the tool body by means of a screw 28. To permit adjustment ofthe indenting wheel, 'the toolbody is recessed,:-as at 30, to provide clearance Ifor the stud 24, and the pla-te 26`is providedwith an elongated slot 32, both of which slots allow the plate 26 and'hence the indenting'wheel 22 to be moved toward andfrom the burnishing surfaces 14, 18 of the tool'body and also, to-some extent, sidewise of the tool body 10. It will be `'apparent froman inspection of Figs. 3 and Llthat the right-hand portion of theburnishing surface of the tool is lcontinuous or uninterrupted along transverse sections so that all of the peripheral face of a heel, including the portion which is to be beaded or indented, when properly presented to the tool, will receive a burnishing treatment.

`In the ordinary use ofthe tool, a heel is presented thereto in engagement with both ns7rsso the burnishing surfaces 111, 18 at the righthand portion thereof and also in engagement with the indenting wheel 22, the lip 16 being inserted in the rand crease of the .shoe and the burnishing surface 18 bearing i against the corresponding face of the heel, thereby to burnish it as well as to guide the tool. As above stated, the burnishing tool may be either vibrated in a manner well known in the art or held stationary. The operator then'moves the shoe, holding it first in engagement only with the burnishing sur- -face` of-the tool as above described until the indenting operation is to be started, at which -tnne -the -shoe 'is held -to establish engagement between its heel and both thelburnishing lsurface and the indenting means. The

work ordinarily being turned in a clockwise direction (Fig.;2), with. respectto .anypoint on the heels surface, the heel will first be burnishcd andithen indented; but it isfto be understood'that the burnishing 'and :the indenting of the heel are carried out simultaneously during a greater'portion of the finishing operation, although at any instantv the burnishing and indenting operations; are being performed at differentpoints on theheel.

IIt will alsocbe apparent that by presenting the work in normal relation to either the indenting wheel .alone or tofonly the burnishing surface at one side lof :the indenting wheel, the `work so presented may either be indented or burnished.

It will now be apparentthata heeLma-y both be completely burnished;and-.simultaneously indented lwith onetransfer ofthe point of contact of the tool and .the .heel thereabout bythe use of a tool -such vasthat disclosedherein, or that: it may be used either as a burnishing' tool or asan indenting tool at the discretion ofthe operator.
