SPECIFICATION forming part of Letters Patent No. 281,365, dated July 17, 1883.

Application filed May 23, 1883. (No model.)

To, all whom it may concern:

Be it known that I, ALFRED HINOHOLIFFE, of Lawrence, in the county of Essex, State of Massachusetts, have invented a certain new which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make-and use the same, reference being had to the accompanying drawing's, forming a part of this specification, in which-- Figure 1 is a top plan view; Fig. 2, a side elevation; Fig. 3, a bottom plan view; Fig. 4, an end View; Fig. 5, a vertical transverse section taken on the line as w Fig. 6, a like view taken on the line 2 z Fig. 7, a vertical longitudinal section; Fig. 8, a section of a finished welt cut by the machine, and Fig. 9 a view showing the welt indented for stitching.

Like letters of reference indicate corresponding parts in the difi'erent figures of the drawings.

My invention relates to that class of weltcutters which are designed to be secured to a operated by hand; and it consists in a novel hereinafter more fully set forth and claimed, by which a more effective device of this character is produced than is now in ordinary use.

In the drawings, A represents the body of the machine; B, the presser-bar, and G the groover. The body is provided with an upwardly-proj ecting side piece, D, which is preferably cast integral therewith, and a detachable side piece, E, which is secured to the body by the screws m m, the side pieces forming the channel along which the welt passes over the bed f. The groover G, or knife for forming the stitch-groove in the welt, is pivoted at its rearend by the journals 4% a in the sides E D, its forward end being provided with the cutting-gouge a", and made vertically adjustable by the screws Z Z, pins h, and fiat steel spring K, the screws acting on lateral projections 22 of the groover, which extend laterally into slots 23 in the side pieces. The pins h are fitted to work loosely in the lower part of the side pieces, E D, immediately underthe screws Z, which are disposed in the upper part of said pieces. The spring K is fitted into a transverse slot, t, in the bottom of the cutter, and is secured by the screw L, the pins h resting on the ends of the spring, so that when the screws Z are turned down or in the groover G will be depressed, forcing the pins h and ends of the K down, and when the screws are turned up or out the groover will be elevated, being forced up by the action of the spring on the pins. The presser-bar B is rendered adjustable by means of the screws Z Z, working in the side pieces, E D. These screws are not threaded where they pass through the side pieces, and are kept in position therein by the retainingpins p, but are threaded where they pass through the ends of the bar B, so that when splitting-knife, N, secured by the screw a, and

opposite this knife, arranged beneath the groover G and bar B, there is a gage, y, secured to the forward part of the side E by the screw 1), a thinner or thicker gage being used according to the width of the welt it is desired to cut. The side D and bottom of the cutter are curved or cut out as shown at Q to such an extent as to open through or into one side of the bed f, and form a throat across which the inclined knife R is disposed, being secured by the screw q. A small wheel, T, provided around its periphery with the sharp teeth (Z, is j ournaled in a slot in the body of the machine, as shown in Fig. 7, the teeth projecting upwardly through the bed f. The side D is removed in front of the knife N, opposite the gageg, to permit a piece or strip of leather to be passed into the cutter, which is wider than the bed f.

In the use of my improvement the cutter is attached to a bench or any convenient support by screws passing through the holes j. A gage, g, of proper thickness to determine the width of the welt, is then secured in the cutter by the screw b, and bar B and groover G respectively adjusted by the screws Z Z, according to the thickness of the welt to be formed. A strip of welt-leather, having its end narrowed and skived or thinned down, so as to pass readily under the bar and groover, is then passed into the cutter until it projects beyond the groover suificiently to be grasped by the hand ora pair of pinehers, when it is drawn through, and the welt S formed in a manner which will be readily obvious without a more explicit description. As the strip of leather passes through the cutter it will be split or have its edge thinned off by the vertical knife N, and its lower edge, opposite the gage g, skived or beveled by the inclined knife R. A stitch-groove, 10, will also at the same time be formed in the under side of the welt by the cutter-gouge r, and a series of indentations, 44, made in its upper side by the wheel T, the indentations made by the wheel being designed as a guide for the workman in forming the stitch-holes when the welt is attached to the shoe.

Having thus explained my invention, what I claim is 1. lhe improved welt cutter herein de-' scribed, the same consisting of the body A, provided with the side pieces, E D, the pivoted groover G, provided with the gouge r, screws Z, pins 71, and spring K, the bar B, provided with the screws 47, the gage g, knives R N, and.

wheel '1, constructed, combined, and arranged 1 to operate substantially as set forth. I 2. In a weltcutter, the pins h, spring K, and screws Z for adjusting the pivoted groover G, substantially as specified.

3. A welt-cutter provided with a wheel for indenting the welt to indicate the position of the stiteh-holes, in combination with-means, substantially as described, for skiving and trimming its edge and cutting a stitch-groove therein, substantially as shown and described.

4. In a weltcutte r, astitch-groover adapted to be vertically adjusted, a knife arranged behind the cutting-edge of the groover and adapted to bevel the edge of the welt, an adjustable presser-bar for holding the welt-strip down to the bed of the cutter and arranged in advance of the groover, a knife for splitting the welt-strip or trimming its edge arranged in advance of the bevelingknife, and a gage for determining the width of the welt, substantially as set forth.

5. A welt-cutter provided with a knife for splitting or trimming the welt-strip, a knife for skiving or beveling the edge of the welt,

' and a gouge for cutting a stitch-groove in the 'welt, in combination with means, substantially as described, for properly guiding the weltstrip and welt to the knives and gouge, substantially as set forth.
