Application filed April 25, 1907. Serial No. 370,157.

To all whom it may concern:

Be it known that I, CHARLES G. BELMEE. of Haverhill, county of Essex, State of Massachusetts, have invented an Improvement in Heel-Burnishing Tools, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a form of rotary burnishing tool adapted to finish the surface of a heel and form an indented or knurled bead or band on the heel close to the upper. Devices of this-character which have been previously employed comprise the circular burnishing iron, which is connected to the shaft and rapidly rotated to polish the surface of the heel, in connection with an indenting wheel which rotates freely with relation to and about the aXes of the iron, so that it may be held in engagement with the heel and rolled over the surface'thereof close to the upper, as the shoe is turned by the operator to perform the burnishing operation. With these devices the heel has often been damaged by reason of the clogging of the indenting wheel, so that it is caused to rotate by the` rotating iron and .to dig out a groove in the heel instead of indenting l it. This clogging is usually caused by the waX in the heel dressing which runs in between the indenting wheel and the rotating iron, preventing free relative rotation of the wheel. Y

In this connection one ofthe objects of my invention is to provide a form of burnishing iron of the above described character with means whereby clogging of the indenting wheel by waX will be prevented.

In finishing a heel it is customary to beat the leather of the heel up to the upper, so as to make a close joint therebetween, Vthis operation ordinarily being performed byV hand with a hammer.

In this connection, a further object of my invention is to perform the burnishing andbeating operation simultaneously. In accomplishing this obj ect I provide the surface of the burnishing iron with gradual indentations, so that its surface is undulating and will deliver a rapid succession of blows to the surface of the heel as it is burnished, thus beating the leather up to the upper. I have found, however, that if the indentations are far enough apart to provide a suitable polishing surface therebetween the blows with which the heel is struck will be too heavy to produce satisfactory results.

In this connection, a further object of my invention is to provide a form of burnishing iron which is adapted to beat the leather up to the upper during the burnishing operation without striking blows on the heel which will be of sufficient force to damage the heel or to interfere with the burnishing operation.

I accomplish these objects by the means shown in the accompanying drawing, in which,

Figure l is a side elevation ofa rotary burnishing tool made according to my invention. Fig. 2 is a central longitudinal section thereof. Fig. 3 is a sectional view upon the line 3-3 of Fig. 1. Fig. Il is a rear end elevation of the tool. Figs. 5 and 6 are detail views of the parts of the indenting wheel. Fig. 7 is a somewhat enlarged view, partly broken away, of the front end of its burnishing iron. Fig. 8 is a side elevation of the modied form of my device. Fig. 9 is a central longitudinal section on the line 9 9 of Fig. 8. Fig. 10 is a cross section on the line 10-10 of Fi 9. Fig. 11 is a similar view showing the in enting wheel removed, and Fig. 12 is also a similar view showing both wheel and bearing ring removed.

As shownV in the drawing, the shaft a is provided with the usual reduced end portion a on which a nut b is threaded, said shaft having a shoulder a2 at the end of said reduced portion.

A shield'or guard-member c is provided, similar to that ordinarily employed with an edge trimming cutter and having the lip at its edge adapted to run between the upper side of the heel and the upper. A burnishing portion c is provided on the inner side of the shield, closely adjacent the edge of the lip, the burnishing surface thereof being provided with a regular series of indentations or depressions c2. Said shield is also provided with a bearing face c3 and a projecting sleeve portion 04, a shoulder 05 being provided therebetween. An indenting wheel or ring d, having a milled or knurled edge, is rotatably mounted between the shield c and the circular heel-burnishing member or iron e, and upon the edge of a bearing ring f,- the latter being in turn rotatably mounted on the bearing face c3. The iron c ismounted on the sleeve 04 and isV adapted to be clamped between the shoulder c5 on the shield and the shoulder a2 on the shaft by means of the nut b, so that both the iron and Shield will be firmly clamped together, and to the shaft. The Width of the face c3 is made slightly greater than Ythe thickness of the wheel d, and ring f, so that kthey may both be free to rotate between the iron e and shield c' when the latter are clamped in position. A series of indentations e" are also formed in the burnishing surface of the iron e, as shown in Figs. l, 4 and 7, said indentations c', of the iron, and c2, of the shield, being equally spaced apart and of the same depth and width, and the surfaces thereof being practically continuous` with the adjacent'burnishing surfaces, as shown in Fig. 7. In clamping the shield and iron together upon the shaft, they are so set with relation to each other that the indentations of one are each other that the indentations of one are opposite the middle of the burnishing surfaces of the other, as shown in Fig. l, so that the burnishing surface of one will be in engagement with the work when a depression in the other is opposite the work, or the burnishingsurface adjacent thereto comes into engagement with the work. Vith this arrangement the work is supported by a burnishing surface at some point, at all times, so that the force of the blows, which are successively delivered by the burnishing surfaces as they come into engagement with the' work, is much less than if the depressions were directly opposite each other. The beating operaticn is thus accomplished simultaneously with the burnishing operation, although the blows are not of suflicient force to dent or roughen the heel or interfere with the burnishing operation.

The wheel or ring 0l is provided with a series of holes d which extend completely therethrough approximately midway between the outer and inner edges thereof, and the inner edge or bearing surface thereof is provided with a series of recesses d2, as shown in Figs. 3 and 5. The outer and inner edge portions of the ring f are also provided with a series of recesses f1, f2, respectively, similar to the recesses fZ, as shown in Figs. 8 and 6. The iron e is provided with a' series of holes e2 which extend axially entirely therethrough, said holes being of suflicient size to register, in part or in whole, with all of the holes d and the recesses d2, and f1. The object of these recesses and holes is to provide spaces for the accumulation of the hot or melted wax which may be forced in between the wheel or ring d and the adjacent burnishing members, and which, if permitted to accumulate between the bearing surfaces, would greatly impede or pre-` vent the relative free rotation above described. i

With the above described construction, the wax not only accumulates in the recesses and holes abve described, but is permitted subsequently to escape through the holes c2 in the iron, as rapidly as it accumulates, so that free relative rotation of the parts will not be prevented thereby.

The object of making the indenting wheel in the two parts (Z and f is for the purpose of permitting rotation of the outer ring d upon the inner ring f, in case the bearing of the latter upon the face c3 becomes ob structed, and of permitting it to rotate upon said face c3 in case its bearing on the edge of theinner ring f becomes obstructed.

In Figs. 8 to 12 I show a form of my invention which, for certain reasons, I convsider preferable to the form already described. In this form of my invention, the burnishing member or iron y, which performs a similar function to the iron fr,

already described, is provided with an indented or undulating burnishing surface g similar to that already described, but, iu stead of providing the sleeve upon the shield, I provide a sleeve g2 upon the iron which projects therefrom, a shoulder g3 being provided at the end of said sleeve, against which a shield 7L, which is adapted to lit on said sleeve, is clamped by the nut Z), and, as the thickness of said shield is somewhat greater than the length of said sleeve, said nut not only acts to clamp the shield and iron together, but also acts to clamp the iron against the shoulder a?, on the shaft, so that the result is the same as in the form of my invention already described.

The face of the iron g next to the shield z. is provided with an annular recess g4, forming a bearing surface at the inner periphery thereof, said bearing surface extending beyond the face of the iron adjacent the shield a distance slightly greater than the thickness of the indenting wheel which is to be employed, and an indenting wheel z", having a milled or knurled edge, is provided between said iron and said shield. A bearing ring j, preferably of brass, is rotatably mounted upon the bearing of the iron, the thickness of said ring j being` slightly less than the length of said bearing so that said ring will be free to rotate thereon when the iron and shield are clamped together. The indenting wheel z' is provided with an annular rib z" at its inner edge which projects therefrom to an extent nearly equal the depth of groove g4, so that it is thus provided with a bearing surface of the same width as the width of that provided on the outer periphery of the ring j. The thickness of said rib z" is somewhat less than the distance between the outer surface of the ring and the outer side of the annular groove g4, so that a space is provided between said rib z" and the outer side of said groove g4, as shown in Fig. 9, which may serve as an oil chamber and in which the wax may accumulate.

The shield L is provided with an indented or undulating burnishing portion L, similar to that of the iron g and having the indentations therein alternately arranged with relation to the indentations of the iron as before described. The ring a' is provided with a series of wax receiving apertures or recesses 'i2 and the inner and outer peripheries of the bearing ring j are also provided with wax receiving recesses j', jg, while the iron g 1s provided with a series of apertures gf through which the wax may escape, as in the form of my invention already described.

With the form of my invention last described I am enabled to provide a much broader bearing surface for the indenting wheel or ring than am enabled to provide with the other form of my invention, so that the bearing surfaces become worn ,much more slowly, and the wheel is much more effectively held against lateral tipping than in said other form, thus greatly lessening the friction.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is 1.
