THOMAS SMILEY,

OF ALB'IA, IOWA.

Leners Patent No. 88,920, amd April 18, 1869.'

IMIPROVED TOOL FOR SHAVIN'G- THE EDG-ES OF THE SOLES OIF BOOTS AND SHOES.

The Schedule referred to in these Letters Patent and making partei the lame.

To all whom it may conce/rn:

Be it known that I, THOMAS SMILEY, of the town of Albia, in the county of Monroe, and State of Iowa, have invented a new and useful Machine for Shaving the Edges ofthe S'oles of Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation thereof, reference beingA had to the annexed drawings, making'a part of this specification, andthe letters and figures of reference marked thereon, in which`l Letter A is a perspective view of theupper or top part of said machine, as the same is completed and in Yworking-order. v v

Letter B is a perspective view of the iront side of said machine. y

Letter G is a view of the knife of said machine.

Letter D is aview of the piece of metal attached by screws to the holder of said machine, and in front of the knife.

This piece, represented by the drawing marked D, I will call the front section. In it are the grooves for holding and regulating the sliding gauge. There is also attached to it the guard, marked on the drawings B and D by thetgure 1.

Letter Erepresents the sliding gauge.

This invention relates to an improved device for shaving the edges of boots and shoes; and

It consists in the peculiar construction of the front section, carrying the adjustable gauge, or guide, and its application to the shaving-knife stock, as will be hereinafter more fully described. y

To enable others skilled in the art to make and use my invention, I wil1- proceed to describe its construction and operation.

I take a piece of cast-iron, (steel, brass, copper, or

.other metal may be u'sed, if desir-erh) about a foot long,

an' inch wide, and a quarter of an inch thick. At about one-quarter of the distance from each end of this piece of metal, I bend it upward about an inch, and with a curve that wilI correspond to the curve in the sole of a boot'or shoe. A

This will leave at the top of the arch a level space, something more than an inch long, where I make a socket, in which to place the knife, extending said socket downward at each side of said arch, so that it may correspond to the shapeof the knife, as shown in the drawing marked G. Y i I also remove, 'or cut out the metal at the level space on top of said arch, so as to leave nothing under the front part of the knife.

In constructing th' piece, which I call the holden I am careful to give that side which is next the guard, figure l, and which side is represented by the figure 2, on the drawing marked B, the proper curve, so that it may be able to follow the bends in the sole of th`e boot or shoe, and especially that bend which is under the instep. A

, In front of the holder, and on each side of the arch, I cut out sockets, or spaces, where Imay attach with screws the front section, which is the piece represented by the drawing marked D.

-I next proceed to construct the shaving-knife in the form represented by the drawing marked U.

This knife should be constructed out of the best steel that the maker can procure, and, to operate properly, it should be made and kept very sharp.

This knife I place in the, socket at the top ofthe arch in the holder, and fasten it at each side of said arch, by screws, as shown in the drawing `marked A.

I then make the front section, represented by the drawing marked D, so as to correspond in shape with -the arch ofthe holder.

In this front section, I make a groove at the top, in which to place the sliding gauge, and one at the side, by means ofwhich said gauge may be regulated.

In the top of this front section, and at the end opposite to the groove for the sliding gauge, I insert the small metal guard represented in the drawings B and D by the figure 1. i

This front section and guard I make of cast-iron. The guard need not be more than an eighth of an inch in height and width, and about the thickness of the back of an' ordinary penknfe-blade...

I attach the front section to the holder by means of screws, as shown in the drawings marked A andB, and adjust it in front of theshaving-knife in such a way as to let said knife have the operation of a spokeshave.

I then construct the sliding gauge of the same maf terial as the holder and front section, and in the form represented by the drawing marked E.

I place this sliding gauge in the groove at the top ofthe front section, and regulate it by the groove and screw at the side of the front section, as shown inthe drawings A and B. A

Having explained the construction of my machine, I will describe its operation, which is as follows:

' Having regulated the sliding gauge to correspond to the thickness .of the sole which is to be shaved, I place the machine so as to have the guard, figure 1, to pass along the upper side of the sole, and the sliding gauge to pass along the under side of the sole.

I then draw the machine along the sole in such a manner that the knife may shave the edges. I thereby save from one-fourth toene-half the time required to do the-work with tools now in use, and also finish the work so perfectly as to render unnecessary the use of the rasp and buffer, which are now employed for finishing and completing the work on the edges of the soles.

What I claim as my invention, and desire to secure by Letters Patent, is

The front section D, constructed as described, and slotted, to receive the adjustable right-angular gauge E, and its adjusting-screw, and adapted to be applied tothe shaving-knife stock, in the manner herein described, for -the purpose specied.

I THOMAS SMILEY.
