L. N LELAND, OF GRAFTON, MASSACHUSETTS.

IMPROVED DEVICE FOR CUTTING WELTS.

Specification forming part of Letters Fatent No. 39,2%, dated July 21, 1863.

To all whom it may concern Be it known that I, L. N. LELAND, of Grafton, in the county of Worcester and State of Massachusetts, have invented a new and iIn Aproved device for cutting leather into narrow strips, designed more especially for cutting welts forboot-legs; and l do hereby declare that the following is a full, clear, and exact description of thel same, reference being had to the accompanying drawings, making a part ot' this .-specitication, in whichspending parts in the several figures.

This invention consists in the employment or use of a cylinder provided with a series of cutters placed at equal distances apart, and in using in connection therewith a grooved cylinder arranged to operate conjointly with the cylinder ot' cutters, so as4 to cut in a perfect manner the leather which is passed between the grooved cylinder and cutters.

To enable those skilled in the artto make and use my invention, I will proceed to describe it.

A represents a cylinder, which is placed horizontally in the lower part of a fra-me, B, and has a series ot'. circular cutters, C, placed upon it at suitable and equal distances apart. The cylinder A may be of iron, and the cutters C should be ot' steel. Directly above the cylinder A, and in the same axial plane, there is another cylinder, D, which is grooved circumferentially, as shown at c. These grooves a are in line with the cutters C, the edges of the latter fitting'in the former, as shown clearly in Fig. 2. The groovesa are of form, corresponding to the edges of the cutters. To one end ot' the cylinder D there is attached acrank, E, by which motion is communicated to the upper or grooved cylinder, D. It' desired or necessary, the two cylinders may be connected at one end by gears. The leather to be cut (shown in red in Fig. 3) is passed between the two cylindersA D, and is cut into strips by the cutters C, the latter in consequence of working in grooves a, acting like shears, and making a clean, smooth cut. These grooves a also keep the edges ot' the cutters in good condition. They are not liable to be blunted or have their keen edge taken from them by working in contact with the periphery of a cylinder, as has hitherto been the case. The grooved cylinder D is of metal.

The device as a whole is extremely simple, and will perform its workr'apidly and well.

I do not claim, broadly, a cylinder of cutters l working in connection with another cylinder, for such cutting,` devices have been previously used for'varions purposes but,

Having-thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The cylinder A, provided with a series ot' circular cutters, C, in combination with a cylinder D, having a series of V-shaped grooves, a, made circumterentially in it to receive the edges of the cutters, substantially as and for the purpose set forth.
