THOMAS H. QUICK, OF NEW YORK, N. Y.

IMPROVED MACHINE FOR CUTTING SUGAR.

Specification forming part of Letters Patent No. 28,903, dated June 26, 1.860.

- To all whom t may concern:

Be it known that I, T. H. QUICK, of the city, county, and State of New York, have invented a new and Improved Machine for Cutting Sugar, and I do hereby declare that the following is a full, clear, and exact de scription of the same, reference being had to the accompanying drawings, forming a part of this specication, in which- Figure l represents a longitudinal vertical section of my invention, the line x x, Fig. 2, indicating the plane of section. Fig. 2 is a plan or top view of the same. Fig. 3 is a horizontal section of the same, taken in the plan indicated in the line y y, Fig. 1.

Similar letters of reference in the three Iigures indicate corresponding parts.

The object of this invention is to cut up loaves of sugar in regular cubic lumps of a To accomplish this, I first cut up the loaf in slabs or disks oi' the thickness of about three-quarters of an inch, and these disks I pass through two pairs of rollers or through between two different pairs of movable cutting-surfaces-one pair to cut up the disks into four-sided prisms and the other pair to cut up these prisms into cubic lumps ofthe desired size and shape.

My invention therefore consists in the arrangement and combination of two pairs of movable cutting-surfaces having their cuttingedges one transversely to the other, ai'd at such distances one from the other that the slabs or disks previously cut from the loaves in passing through between said cutting-surfaces are Iirst cut up in prismatic sticks, and afterward, by the action of the second pair of cutting-surfaces, in the desired cubic lumps.

To enable those skilled in the art to fully understand and use my invention, I will proceed to describe its construction and operation with reference to the drawings.

A is a frame, made of wood or of any other suitable material strong enough to sustain the strain to which it is subjected during the operation. This frame forms the bearings for the cutting-rollers B B and G C, which are arranged one pair above the other, as clearly. shown in Fig. l. The several rollers are connected by a series of gear-wheels, and they are rotated in opposite directions by manual or other power. They might, however, be arranged in a different position toward each other from the one shown in the drawings,

and instead of each pair of rollers one roller and a corresponding flat surface might be eniployed. The rollers B B are fluted, so that the same form a series of cuttingedges, c, about three-quarters of an inch apart, and the rollers themselves are placed far enough apart to admit the slabs or disks of sugar, as represented in red outlines in Fig. l. As these disks pass through between the luted cutting-surfaces of the two rollers B B, they are cut up in prismatic sticks; and it will be easily understood how the same thing will be accomplished by using one iiuted roller over a Iluted plate, which latter may be in motion or not, as may be desired. The second pair of rollers, C C, are grooved in a direction transl versely to the axle, as clearly shown in Fig. 3, forming a series of cuttingedges, b, running in a direction at right angles to the cutting-edges of the rst pair of rollers, and at the same distance apa-rt one from the other. These rollers may be round or polygonal, and instead of two rollers one roller and a correspondinglygrooved plate might be employed with the same effect. The prismatic sticks of sugar formed by the first pair of cutting-rollers in passing through between the second pair of rollers, G C, are cut up in cubic lumps of the desired size, as clearly shown in Fig. 3 in red outlines, and the lumps thus formed are collected in a basket or in another suitable receptacle placed under the rollers.

This machine is very simple. The cuttingrollers can be made entirely of cast-iron, and the cutting-edges, when dull, are easily sharpened, and a very large quantity of sugar can be cut up by it in cubic lumps in a short time. The lumps drop from the cutting-rollers without any further assistance, and there i's no danger whatever that some of the lumps might stick between the cutting-edges and disturb the correct action of the machine.

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

The arrangement and combination of two pairs of movable cutting-surfaces having their cutting-edges one at right angles to the other, and at such distances one from the other that, by the successive action of said cutting-surfaces, the sugar is cut up in the desired shape, substantially as herein described. f
