ICE-HOUSE.

SPECIFICATION forming part of Letters Patent No. 253,'790, dated February 14, 1882.

Application 'filed November 4, 1881.

To all 'whom z't may con'cew Be it known that we, ARTHUR VON KRAUSE and MATHIAS KUHNEN, of Blauveltville, Rockland county, New York, have invented a new andlmproved Ice-House, of which the following is a clear, full, and exact description.

The object of our invention is to facilitate freezing large blocks of ice without the use ot artificially-cooled air, andiin the house in which the ice is to be stored.

The invention consists in an ice-house constructed with a fiat tank, either fixed or vertically adj usted, and provided with a series of funnelsfrom which wires or equivalents extend down to the bottom of the ice-chamber, down which wires the waterflows and freezes, gradually formiug a solid block ot' ice in the icechamber. After a few days the wires become loosened and are withdrawn. A circulation of cool and rarefied air is maintained in the ice-chamber.

Reference is to be had to the accompanying drawings,`forning part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a cross-sectioal elevation of our improved ice-house, and Fig. 2 is a cross-sectional elevation of a modification ot' the same.

The ice-house A is constructed with a flat water-tank, B, of wood or metal, in its upper part, and this tank is provided with a series of slender downwardly-projecting funnels, C, the centers of which are separated from eight to ten or twelve inches transversely and longitudinally. The lower ends of these i'unnels G fit in apertures in a horizontal partition, D, arranged a short distance below the bottom ot' the tank B and forming the top of the icechamber E. From each funnel G a wire or equivalent, F, extends down to the bottom G of the ice-chamber E, these wires being suitably supported in the funnels, but not fastened on the bottom of the icc-chamber. A series of wires, F, arranged in longitudinal and transverse rows, will thus cross the ice-clamber vertically.

A water-pipo, H, provided with a cock, J, conveys the water from a suitable tank or pum p to the tank B.

The ice-house A is constructed with outer side walls, K, and inner side walls, L, an air- (No model.)

cation with a suction-fan, P, or .some other i device for drawing off the air.

If desired, the ice-chanber E may be provided with a series of partitions, Q, provided with apertures R.

The entire device may be arrangcd in a pit underground, as shown in Fig. 2, the coustruction otherwise remaining the same.

If desired, the tank B, the funnels C, and the horizontal partition D may be made vertically adjustable, either by means of screws or ropes and pulleys.

` The building may be made ot' wood, stone, or metal.

The space between the tank B, the funnels C, and the horizontal partition D is preferably filled with some non-conductor of heat--such as sawdust, &0.-to prevent the freezin g of the water in the funnels.

The operation is as follows.: If the fan or other device P is operated, it will draw all the air out of the ice-chamber E, and fresh cool air will enter into the same through the aperturcs O and M, the air circulating through the ice chamber, as indicated by the arrows. Water is admitted into the tank B through the pipe H, and this water will flow through the funnels C and down the wires F, only suflicient water being admitted into the tank B to cause the water to flow down the wires F in a very thin layer. The cold air circulating through the ice-chamber causes the thin layer of water on the wires to congeal, and as the air in the ice-chamber E is more or less rarefied, the congealin g process is facilitated. The layer of ice on the wires gradually thickeus and gradually fills up the space between the wires, and a block of ice is formed. After a few days the heat passing down the wires causes them to be loosened and they are withdrawn, and the apertures or channels they formed will freeze up. A solid block of ice eight feet square and xoo Care must be taken not to allow the flow of water to become' so copions that water will collect on the bottom of the ice-chamber.

If the partitions Q are pro vided, several blocks will be formed, which can' be moved successively. If the tank B is made vertically adjustable, a block or bloeks of ice of a certain thiokmess can-be formed. The tank can be raised and another block can be formed on the first, and in this manner the thiokness ot' the block can be gradually inereased The longitudinal apertnres Originally made by the wires F greatly faoilitatecntting the large block into smaller cnbes or blocks.

We are aware that iee has been naturally as well as artificially formed in snoeessive layers by tricklin g in a thin stream over a twig, pole, rope, orcord; also, that it has been made to flow from a tankover small pendent tubes into' which steam or hot water is injeoted to loosen the formen" ice therefron. Our object is to avoid this by guididg the water in funnels, so that it will triokle and be formedinto ice around pendent wires, which may be readily drawn out in a few days, leaving the ice solid and unaft'eeted by any application of heat, as well as saving a great deal ot' time, labor, andex- ARTHUR VON KRAUSE.
