UNITED STATES PATENT OFFICE.

CHARLES YV. CHAPMAN, OF HARTFORD, CONNECTICUT.

ICE-BREAKER.

Specification of Letters Patent No. 28,966, dated July 8, 1860.

To all whom it may concern:

Be it known that I, CHARLES IV. CHAP- MAN, of the city of Hartford, county of Hartford, and State of Connecticut, have invented a new and useful Improvement in the Mode of Constructing I ce Breakers or Granulators; and I do hereby declare that the following is a correct description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The nature of my invention consists in f the construction of a cylindrical shaped metallic case with a toothed disk stamper to break ice into fragments for various purposes.

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

In the drawing, Figure l is a side view of the machine; Fig. 2 a vertical section through the center; Fig. 3 a plan of disk, piston, cylinder, &c.

I construct my cylinder A of sheet metal of a requisite size, with an opening in the lower part to receive the drawer B, to contain the lump of ice placed in preparatory to being crushed and granulated.

The top or cover C has a hole in the center for the piston rod E, to work through.

I form my crusher or granulator D, of cast iron with aseries of long spikes or knives on the lower disk of the same, and is attached to the rod E, that works through the hole in the top C, and is actuated with I the hand by the knob or handle F, assisted by the spiral spring Gr or its equivalent.

The spiral spring Gr is made of suflicient tension to sustain the disk D, above the drawer so that the drawer and ice can be removed, without inconvenience after being operated on.

All the iron work will be tinned to prevent rust.

To operate the machine, put into the drawer B a lump, or lumps of ice of a suitable size; close the drawer and pound with the disk, and the teeth will out the ice into small pieces, so much desired for ice cream makers and for various other purposes for which the article is used.

The utility of this vmachine is in the economy of operation. The ice in the drawer being surrounded by the cylinder, prevents the unpleasant dispersing and waste of the same, as is the case when broken up in the customary manner.

I do not wish to confine myself to any particular form of the spikes orknives on the disk, or to the length or size, or to the precise form or size of the cylinder.

lVhat I claim as-my invention and desire to secure by Letters Patent is- The arrangement of the cylinder A, drawer B, and toothed disk D, in combination for the purpose in the manner herein set forth and described.

CHARLES W. CHAPMAN.

Witnesses IVM. VINE, WILLIAM CHAPMAN.
