PATENT OF NEW YORK, N. Y.

ICE MAKING AND CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 638,577, dated December 5, 1899.

Application filed April 12,1899. Serial No. 712,802. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES E. HARRIS, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Ice Making and Cutting Machines, of which the following is a specification.

The object of this invention is the production of a machine by means of which clear ice in small particles of various sizes can be produced for regelation.

The means heretofore used to prepare ice for regelation has produced regelated ice of a cloudy appearance by virtue of the entrappin g of a considerable number of air-bubbles between the particles of ice, resulting to a great extent from the ice being cut in particles of too small dimensions and also by reason of being exposed to the air while being broken or cut in small particles.

The apparatus which constitutes this invention can produce ice in particles of various sizes, cut or broken under water, thereby avoiding the excessive entrapping of air, and the product when regelated producing clear we To these ends my invention consists of a revolving freezing-cylinder, for the accumulation of ice, and adjustable cutting-tools, operating under Water, to detach the ice in suitable condition for regelation.

Referring to the drawings, in which like parts are designated by similar letters of reference, Figure 1 shows an elevation of my invention, partly in section on the line C D. Fig. 2 represents an end View with a frag mentary section, taken on the line E F. Fig. 3 is a partial elevation of the frame of the machine with conveyer and extended trough. Fig. 4 shows a plan of Fig. 3. Fig. 5 represents a sectional elevation of the device,taken on the line G H. Fig. 6 shows a fragmentary plan. Figs. 7, 8, 9, and 10 represent details'of the cutting devices.

Referring to the drawings, the freezing-cylinder is shown at E, to which are secured the long hollow journals cl and d, which turn in the combined bearings and stuffing-boxes cl and 61 the latter being a part of and cast with the trough F. Glands d d are fitted to the stuffing-boxes to prevent the leakage of water shown in Figs. 3 and 4.

from the trough F. To the ends of the hollow journals (1 and d are fitted glands d d", which fit the stuffing-boxes 61 to secure tight joints between the pipes 12 and t' and the hollow journals (Z and d, preventing the escape of the refrigerant.

It will be noticed that the trough F constitutes and forms part of the frame or housing for the machine. The side f is concaved and concentric with the freezing-cylinder E, and it continues under the said cylinder until it runs into the plane surface f At f andf straight vertical ends are shown. A straight vertical leg is shown at f which joins with the secondary trough f for the conveyer R. At the junction of the' leg f and trough f a concaved plate f is secured by bolts 1, the said plate extending between the ends f and f An inspection of Fig. 5 will clearly show that the sides and ends of the trough F are brought above the level of the plate f which in turn is situated above the cutting-tools q and q, allowing, in the first place, the cuttingtools to operate under water and preventing the water contained in the trough F from overflow in the secondary trough f.

To properly carry 0d the particles of ice, the secondary trough f is extended by bolting'to the side f the extended trough R, as

This trough R contains the opening r for delivering the particles of ice. A conveyer R revolves in the tronghf and its extension R, the shaft '2; of said conveyor turningin the j ourual-boxes n, being driven by any suitable source of power.

At P is shown a shaft with blades P P, &c., turning in journal-boxes P, a pulley P being secured to the shaft and driven by any suitable power. The object of the blades P" P, &c., is to sweep the particles of ice, after being out from the freezing-cylinderE, up the curved plate f and into the trough 1.

At It is shown a horizontal pipe leading from the pipe g, with its valve g, by means of which the trough is fed with water, the pipe It being perforated with numerous holes on its bottom side. An outlet 12 is provided at the bottom of the trough F to drain and clean the same.

To the hollow journal 61 is fixed the spurgear G, which can be driven by any source of power. The said gear communicates its motion to the freezing-cylinder E.

The bevel-gears H and H, shaft J, and bevel-gears K and I communicate motion to the shaft M, which in turn actuates at the proper intervals the knives q and q.

The gearing is proportioned to rotate the freezing-cylinder E one revolution while the shaft M makes one-half of a turn.

The shaft M carries grooved cams h by which the cutting-tools are kept in a proper position to cut ice from the freezing-cylinder E during one revolution of the said cylinder and are then moved out of position from said cylinder for the next revolution, to allow the accumulation of ice, and so on alternately. To secure these ends, one half of the groove in each cam M is cylindrical and concentric with the shaft M, as shown at a b 0 while the other half of the groove, a e 0 is somewhat flattened and closer to the center of the shaft M. The forked ends n of the spindle N carry pins M, with rollers n, which fit the said grooves, and when the portion a b 0 comes in gear with the rollers n the position of the spindle N",with the set of knives, is not disturbed, and the ice is cut from the cylinder; but when the portion a e 0 comes in contact with the rollers 02 the spindle N, and consequently its set of knives, is drawn toward the center of the shaft M and away from the cylinder E. The positions of the knives are thus alternately against and away from the freezing-cylinder. The distance between the ends of the spindles Nand Nis adjusted by the turnbuckle n to gage the ice cut from the freezing-cylinder at the proper thickness.

The grooved cams M are placed on the shaft M so that one set of knives, as in the holder Q, are against the cylinder, while the knives next adjacent, as in the holder Q, are away from the same, by which alternate sets of knives cut bands of ice off the cylinder, while the remaining sets of knives allow the revolving cylinder to collect ice.

The knife-holders Q Q" are substantial castings, with the vertical pockets g and feet g reciprocating in the guides V V. Lugs g are provided for securing spindles N, the said lugs being tied to the vertical walls of the pockets by the ribs q". Openings Q10 are left to insert nuts 92 for securing the spindles N.

The knives are held in upright positions in the cavities Q, where adj usting-pieces g assist to properly locate and secure them with the screws (1 This disposition of the knives prevents bending when in use and avoids the tremor consequent to cutting-tools when not properly secured.

Stuffing-boxes f are cast with the legs f of the trough F, through which the spindles N reciprocate.

The disposition of each set of knives is novel, the knives in each set being alternately placed on difierent levels with respect to the center of the cylinder, as shown at q and q, so that the upper level of knives cuts the first strip of ice and the lower level cuts the remainder, the edges of the knives over: lapping to thoroughly clean the cylinder of ice. The overlapping edges of the knives are seen at t t and 25 25 By this disposition of the knives plenty of clearance is given to the cutting edges, and the liability of their becoming clogged with ice and breaking is avoided.

It will be seen that the actions of the knives with respect to the revolving cylinder are automatic in operation.

In Fig. 10 I show a modified form of operating the knives in which they are continuously held against the revolving cylinder. The construction is cheaper, and the shaft M, with the cams h is dispensed with. The spindle N in this modified form is made in one piece, with a screw-thread 8 working through the threaded lug The hand-wheel S adjusts the position of the knives with respect to the revolving cylinder E. The end of the spindle N is turned down and fitted with two collars n and n", which work easily against the lug (1 allowing the spindle N to turn and move the knife-holder.

To operate my device, ammonia or some other refrigerant enters the pipe b, on its passage to the freezing-cylinder E, through the hollow journal (I. The said refrigerant ex pands and produces its refrigerating effect on water adhering to cylinder E. The refrig erant, after expanding in the freezing-cylinder E, leaves the same through the hollow journal 01 and piping 2'. The ice which is frozen on the cylinder is cut from the same by the knives q q and deposited on the curved plate f where the blades P" P, &c., sweep it into the troughf for the conveyer R to carry it to the opening 1' in the extended trough R, when other machinery is brought into action to regelate the particles of ice.

Having fully described my invention, I desire to secure by United States Letters Patent and claim 1. An ice making and cutting machine comprising; a revolving hollow freezing-cylinder long hollow bearings for said cylinder, with stuffing-boxes secured thereto; a cleanable water-trough with ends constituting combined bearings and stuffing-boxes; a perforated supply-pipe with valve; knife-holders with knives securely held in vertical pockets with adjusting plates and screws; a cam-shaft with grooved cams,one half of the said grooves being concentric with center of cam-shaft, and other half flattened and closer to center of said shaft; spindles with forked ends and rollers, transmitting movements from grooved cams to knife-holders; turnbuckles to vary the lengths of the spindle with forked ends; a gear-wheel secured to hollow bearing of revolving cylinder; bevel-gears with shaft and pillow-blocks to transmit motion from revolving cylinder to cam shaft; revolving blades and conveyer all as substantially described.
