ICE-MACHINE PRESS.

Specification of Letters Patent.

Patented Jan. 14, 1908.

To all whom it may concern:

Be it known that I, DANIEL L. Hommn, a citizen of the United States, residing at cw York, in the county of New York and State of New York, have invented certain new and useful Improvements in Ice-Machine Presses, of which the following is a specification.

. This invention is for the rapid manufacture of merchantable blocks of ice by the pressing and regulating of small particles of me into a solid mass.

-To enable a continuous operation, and great efiiciency in production, a double acting hydraulic pressure cylinder and two ice presses are arranged in ahnement, or tandem, the presses being at each end of the pressure cylinder, so that the presses are fed-alter nately and the ice blocks are discharged alternately from each press, which results in saving much time as wel} as greatly increasing the output over the fori'i ier machines 'where only one press was operated by a pressure cylinder. There are other co-acting means which contribute to perfect the operation, and which will be set forth in the speciiication.

The invention is illustrated in the accomanying drawings, in which similar parts liear similar figures of reference wherever shown, in w hich Figure 1 is a side elevation. Fig. 2 is a top or plan view. Fig. 3, 4 are enlarged views of the indicator roller and its support. Fig. 5 is a view of the valve for the ice presses, when open'. Fig. 6 is a view of the valve for the ice presses, when closed.

A bed plate 1 provides a common support for a double acting hydraulic pressure cylin der 2, and ice presses 3,4, one being at each end of the cylinder. The pressure cylinder has heads 5, 6 with stuffing boxes 7, 8, while. heads 9,10 with shilling boxes 11, 12 are provided for the inner heads ol'- the presses, their outer ends having vertically moving gates 13, 14. Within cylinder 2 there is a )iston 15 with rods 16, 17 extending thereirom-into the )resscs and connected to their rams 1h, 19. 11 order to gain ready access to all the piston and rams, the presses 2%, are placed away from cylinder 2 far enough to permit head '5 to be detached. and moved over to head 9, and head .10 to be detached and moved over to head ii, and with gate 12-;

moved up piston 15 may be moved to the open space between cylinder 2 and press 3,

or by moving the opposite heads 6,. 9 and gate 14 piston 15 may be moved to the space between cylinder 2 and press 4. The movement of piston 15 is controlled by a hydraulicvalve 20, for light pressures, and by hydraulic valve 21, for greater pressures, these valves being oi" any of the Well known constructions adapted to the purpose.

Under the presses 3, 4, near their outer ends, there are secured rotary valves 22, 23 which open and close the passage for the ilow of ice particles from pipes 2+1, 25 to presses 3, 4 the passages being open when tlfie rams 18, 19 are at the inner end of their stroke. By placing the valves 22, 23 under the presses any air which may be carried in with the ice particles will be free to escape by the means provided, and will not whiten the ice block, or revent its solidity.

is seen in the views, gate 13 has been moved up, by its odinder 26 to open the end of press 3, ram 18 ms been moved by piston 15 to expel. an ice block and valve 22 is closed while rain 19 is at the inner end of its stroke, gate 14 is closed by its cylinder 27, valve 23 is open and particles are flowing into press 4. Valves 22, 23 are automatically opened by the rams 18, 19, each valve being provided with a stem 28 passing through a stuffing hex 29 and having thereto attached an arm 30 connected to a rod 31.. As valves 22, 23 must rotate in the same directions, in opening, and as rams 13, 1.9 move in oppo site directions when opening the valves, it is necessary to provide a different means for rain 18 to operate valve 22 from that which is used. by ram 19 to operate valve 23, therefore, rod 31 of valve 22 for press 3 is attached to a lever 32 with an intermediate or central fulcrum 33, and at its opposite end lever CiJ-has thereto atiacl i cd a pin 34 which enters press 2% and is pnshcl'l outward by rain 18 to put valve 22 into its open position, as seen in Fig. 5; press 4 is provided with a lcvcr 2. 3 attached to rod Ill of its valve 23, the lever biting 'l'ulcruincd at its opposite end 36, and inicrlncdiately there is attached a pin 337 which enters press. 4 and is pushed outward by rain 19 to put val e 23 into its open position, as seen in Fig. 5; the rams overcomesprings Sfsf which are attached to levers 32, 35 which operate to close valves 22, 2-3 when rams 18, 19 move away from pins 34, 37 to put the valves into the position, closed, as seen in Fig. 6, the ports 39 being covered by rams 18, 19 before the valves are again opened.

After the ice block has been discharged, the movable parts will assume the positions seen in press 4, where its gate 14 is moved down by cylinder 27 to close the press and ram 19 has moved to its inner position Where it abuts pin 37, moving lever 35, overcoming s ring 38 and opening valve 23 to permit t e' ice particles to pass into the press through port 39; when tieram was atthe outer end of its stroke, to expel the ice block, it covered )ort 39 into the press, as

seen in 6, so t at even should t 10 valve be disarranged, or inoperative no ice particles could then pass into the press, this is an extra precaution against any ice particles assing to the inner side of the ram, making it possible for the ice particles to flow in between the ram and its gate. The operation of the rams and valves are alternate and in termittent, with an interval of time for the flow of ice particles to the messes.

The ice particles are gathered from a tank (not shown) by a pump 40 having a suction pipe 41 connected to the tank and a delivery pipe 42 passing to a three way valve 43 connected to pipes 24, 25 heretofore described. A hand wheel 44 is used by the attendant to operate valve 43 to connect pipes 42, 24 and 42, 25 alternately, to permit the flow of ice particles to the valves 22, 23 I under the presses 3, 4. There is also within easy reach of the attendant a handle 45 on a rod 46 connected to a lever'47, iulcrumcd at 48, which operates a clutch 49 to connect and disconnect sprocket wheel 50 to shaft .5101 pump 40 to start and stop the pump.

resses 3, 4, have eriorated linings, (l Patent 730,018,

June 2, 1903, the upper and side perforations in connection with pi es 52, 53 will remove."

any air carried into t 1e presses with the ice particles, and the lower-perforations permit the escape of any Water, so that the ice block is erfectly pellucid. I

11 order to enable the attendant to know the movements and exact (positions of piston 15, and rams 18, 19 an in ester is provided which is composed of a roller 54 resiliently mounted on a stand 55 for rotary contact with piston rod 17 and the contact is made slot 60 of the indicator plate 61 and to the Weight there is attached a pointer 62 which points to double lines of 'graduations 0 to 24 1n reverse order which enable the attendant to observe the strokes or movements of the piston and rams, and their exact positions.
