SPECIFICATION formingpart of Letters Patent No. 225,504., dated March 16, 1880.

Application filed December 26, 1879.

To all whom it may concern:

Be it known that 1, WILLIAM B. ARNOLD, of North Abington, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Machinery for Itasping Pegs projecting into the footreceiving space of a boot or shoe; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of whioh- Figure 1 is a top view, and Fig. 2 a front elevation, of a machine containing my inveir tion. Fig. 3 is a vertical section taken through the toe-rasper revoluble standard and its supporting-column and the bracket thereof, such figure being on an enlarged scale. Fig. 4 is a longitudinal section taken through the sustaining-arm of the heel-rasper.

The nature of my invention is fully set forth in the claim hereinafter presented, the principal object being to enable the toe-rasper supporting-standard to be adjusted to advantage relatively to the heel-rasper, to admit of their being used by one or two persons, as occasion may require.

In carrying out my invention, as represented in the drawings, the standard A, which carries the toe-rasper B, I make as a hollow vertical column, at, having at its upper end a hollow inclined arm, 1), arranged at an obtuse angle to the said part a, the said standard A being applied to a head or base, 0, so as to be revoluble horizontally relatively thereto. To this end the standard is provided at its foot with a journal or pivot, c, to extend into and turn in a corresponding bearing, 61, formed in the head. A set-screw, c, screwed into the head and against the journal, or a slider, f, arranged as shown, serves to clamp the standard in position. The said base constitutes a cap to a vertical column, D, having a bracket, E, projecting from it, as shown, the said bracket serving to sustain a driving-shaft, F, provided with two wide pulleys, G H, all being arranged as shown.

From the cap or base 0 a bent arm, I, formed as exhibited by the drawings, extends and carries a heel-raspcr, K, and its operative shaft L, the said shaft being provided with a fast pulley, g, and a loose pulley, h, arranged as represented, such being to receive an endless belt, z, from one of the two driving-pulleys, G H.

There is journaled in projections L L, extending down from the base, another shaft, M, provided with a fast pulley, 70, a loose pulley, l, and a bevel-gear, m.

An endless belt, a, goes around the drivingpullcy G and either of the pulleys it or Z.

A vertical shaft, 0, journaled in the cap or base 0, and extending through it, is provided with a bevel-gear, p, to engage with the bevelgear m. The said shaft 0 is concentric with and within the revoluble standard, and at top is furnished with a bevel-gear, q, that engages with another such gear, 1", fixed on the lower end of an inclined shaft, 8, arranged as represented. This shaft, at its upper end, is provided with another bevel gear, 8, that engages with a bevelgear, t, fixed on the arbor of the toe-rasping cutter B, arranged within the inclined arm of the revoluble standard, in manner as shown.

From the above it will be seen that the said revoluble standard may be turned around horizontally without disengaging the mechanism for operating or revolving the toe-rasper.

In using the machine the standard is to be inserted within the leg and foot part of a boot, so as to bring the toe'rasper in contact with the pegs that may project into the foot-receiving space of the boot, such boot being moved against the rasper, as occasion may require, to cause the pegs from the heel forward to be suitably rasped. Such having been done, the boot is to be removed and applied to the heelrasper in a manner to cause it to rasp down such parts of the pegs as may be projecting into the heel-space of the boot.

Fig. 5 is a transverse section, on a larger scale, of the rasper, its supporting-disk and driving-gear.

The toe-rasper rests on a disk, 1:, which has projections or studs to extending from its upper surface into holes :0 made in the lower surface of the rasper. This disk also has holes y to receive studs 2 projecting from the hub of the gear t, said disk being separate in other respects from the rasper and the gear. This erative shaft, but with a separate revoluble disk, applied as described, is of advantage in standard, A, for carrying the toe-rasper and several respects. mechanism for operating it, as described.

What I claim as my invention is as fol- WILLIAM B. ARNOLD.
