6 Claims.

This invention relates to the manufacture of wood heels.

Difficulty is encountered in the covering of wood heels for shoes in that the material, particularly in the case of pyroxylin, whichis used for covering them, is often cut by the sharp edges of the wood heel blocks, especially at the edge where the attaching face and the rear and side surfaces intersect. The angle between these surfaces, especially at the rear end of a high Louis heel, is quite acute, and the edge, as formed upon the hard wood by two separate cutting operations, one for each surface involved, is dangerously sharp and often cuts through the heel cover as the cover is stretched over the heel, or damages it so badly that the heel becomes spoiled after a little wear.

This difficulty has been dealt with in the past by treating the objectionable sharp edge on a sand 90 wheel by hand, which is expensive and produces irregular and inaccurate results.

The object of the present invention is to avoid this difficulty by dulling this sharp edge in an expeditious, accurate and uniform manner. Accordingly I have provided a simple and inexpensive machine having a guiding table with a surface closely adjacent to a rotary rubbing tool which is preferably ribbed on its operative surface and conveniently projects through a suitable hole in the table. Inasmuch as almost no material is removed from the heel block in the operation contemplated, the heel block may be held in the operators fingers, with its attaching face resting on the table, and slid around in light contact with the tool from one side to the other, with the result that the undesirable sharp edge is suitably dulled.

Advantageously, also, I provide a rotating brush, flush with the surface of the table against which any splinters resulting from the operation and hanging to the work piece may be removed in the same manner.

These and other features of the invention comprising certain combinations and arrangements of parts will be apparent from the following description of a preferred embodiment of the invention shown in the drawings, in which Fig. 1 is a perspective view of the machine;

Fig. 2 is a side elevation; and

Fig. 3 is a detail of the rotary tool.

The illustrated machine comprises a frame ill having two extending arms l2 on each side to hold boxes M for the work pieces. The frame it supports a flat table It provided with a round hole l8, below which is located a vertical spindle motor 29. The motor spindle carries a rotary tool 22,

preferably as shown in Fig. 3.

The tool 22 is disk-shaped and has a vertical plain circular edge merging into a horizontal ribbed shelf 26, which is located just flush with, or at least not below, the surface of the table [6. A ribbed conical surface 28 rises from the shelf 28, a short distance inside its edge, forming an obtuse angle 29 between the surfaces 26 and 28. The tool 22 rotates clockwise as seen in Fig. l.

lhe motor spindle is preferably provided with a pulley, shown as covered by its driving belt 30 in Fig, 2, which operates a wire brush 32. This brush has its front side lying on the table It and is preferably made of brass wire.

The tool 22 is covered by a guard 34% which is formed with two gage plates 36 (Fig. 1) and 33 (Fig. 2) wrapped around the tool 22 and ending at points preferably a little less than 180 apart on the periphery of the tool, leaving a. little more than half the periphery exposed.

In operating the machine, the operator places a heel it on the table with its attaching face down and its breast toward him, as shown in Fig. 1, and slides it over to a position somewhat to the rear of that shown in Fig. 1, with its right edge it against the. gage plate 36. He then slides it on the table without substantial alteration in its orientation, keeping the edge G2 in light contact with the conical surface 28, in the angle 29, until he has brought the left edge 44 to the gage plate 38. This operation breaks down the sharp edge' lZ- bl. Such portions of the originaily sharp edge as are bent downward are rubbed away or broken up by the surface 26. In

case any splinters are left clinging to the heel the operator will run the heel around the brush 32, in the same manner as already described, which will remove them.

Having described by invention, what I claim as new and desire to secure by Letters Patent-of the United States is:

l. A rimming machine for wood heels comprising a flat table, and a percussive tool moving substantially flush with the surface of the table whereby a sharp edge of a heel surface resting on said table may be dulled.

2. A rimming machine for wood heels comprising a fiat table having a round hole in it, and a ribbed circular rotary tool mounted in said hole, the ribs extending in a direction which intersects the plane of the table.

3. A rimming machine for wood heels comprising a flat table having a round hole in it, a circular rotary tool mounted in said hole and having ribs extending transverse to said table,

means for rotating the tool, and a guard extending part way aroundthe tool.

4. A rimming machine for wood heels com prising a flat tablehaving a round hole in it, a

circular rotary tool mounted in said hole and having ribs extending transverse to said table,

edge of a heel surface resting on the table in contact with the tool.

6. A rimming machine for wood heels having I a table with a round hole in it, and a rotary tool running in the hole, said tool having a flattish annular ribbed surface substantially flush with the surface of the table, and a second circular ribbed surface rising from said fiattish annular surface, to providean angle between said two surfaces, the ribs on said second-named surface running in a direction which intersects the surface of the table.
