APPARATUS FOR THE MANUFACTURE OF PLATE OR BLOCK ICE.

SPECIFICATION forming part of Letters Patent N 0. 710,656, dated October 7, 1902.

Application filed May 31. 1902a Serial No. 109,634. No model.)

To all whom it may concern.-

Be it known that I, EDWARD ISARRATH, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in vented certain new and useful Improvements in the Manufacture of Plate or Block Ice, of which the following is a specification.

My invention has relation to the manufacture of plate or block ice in a pure crystallike state free from air-bubbles and needles.

The principal objects of my invention are, first, to provide suitable apparatus for manufacturing artificial plate or block ice from constantly-flowing water by means in which the water to be frozen is delivered to a container and stilled and overflows onto an artificial freezing platform or medium and then upon successive strata of ice formed thereon until a plate or block of ice has been built up by successive accretions, and, second, to provide suitable apparatus for economically and efficiently carrying out the said invention of forming artificial plate or block ice.

My invention, stated in general terms, consists of an apparatus for making artificial plate or block ice in substantially the manner hereinafter described and claimed.

The nature, scope, and characteristic features of my invention will be more fully understood from the following description,taken in connection with the accompanying drawings, illustrating a series of forms of apparatus for carrying out my said invention, in which- Figure l is a view, partly in longitudinal central section and partly in elevation, of one form of an apparatus for carrying out my said invention of making artificial plate or block ice; and Figs. 2 and 3 are similar views of two other types or forms of apparatus for carrying out the same.

Referring to the drawings, A in Fig. 1 represents one form of freezing medium or plate, contisting of a hollow rectangular or other shape platform a, through which a freezing fluid, as brine or ammonia, from a suitable source (not shown) is permitted to constantly flow therethrongh. Arranged adjacent to one end of the hollow platform or medium a and preferably abutting against the same is a container or receptacle a, one portion of the wall a of which container or receptacle projects above the opposite wall a of said receptacle or container for holding a volume of water continuously supplied thereto from a suitable source (not shown) through the inletpipe a, having a regulating-cock a. The water enters the receptacle a below the upper surface of the platform or medium a and constantly flowing through the inlet-pipe a under more or less pressure from the source of supply spreads out within the container or receptacle a and in rising therein is stilled to the point where it overflows onto the freezing medium A and so continues to flow over successive strata of ice formed on the freez ing medium until by successive accretions of ice formed therefrom on the medium there has been built up an artificial plate or block of ice of the required dimension. The force wit h which the Water flows into the receptacle a can be readily regulated by the cock a The water flows into the receptacle and by expanding or spreading out is stilled, so that it overflows from the container quietly over the said medium A. At the left of the freezing medium A is located a ledge B for catching and directing any surplus Water from the ice-forming medium. This surplus water flows therefrom into a suitable receiver (not shown) for use over again, or it may be discharged into a waste-receptacle, if preferred.

In Fig. 2 the freezing platform or medium A is provided internally with embedded tubes or pipes I), through which the freezing media by a circulatory system passes for bringing and maintaining the surface of the platform into a condition for freezing water passing over the same to form ice.

In Fig. 3 the platform or medium A is internally provided with rectangular-shaped tubes 1), alternating with contiguous solid blocks 11 Through the tubes 1) the freezing media is circulated for preparing the platform or medium A for ice-making.

The ice formed in the manner hereinbefore explained is crystal-like, free from air-bubbios and needles, and is made in much less time than hitherto it was thought possible to make plate or block ice and of a far greater thickness and uniformity in a given time.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An apparatus for manufacturing artificial plate or block ice from constantly-flowing water, comprising a platform, a freezing medium arranged beneath the platform, a source of flowing-water supply, means for receiving' and stilling the water from said supply and an outlet or delivery from said means located adjacent to one edge of the upper face of said platform and arranged to permit the stilled water to flow in film form over the platform, substantially as and for the purposes described.

2. An apparatus for manufacturing artificial plate or block ice from constantly-flowing water, com prising a platform arranged in substantially a horizontal plane, a freezing medium located beneath the platform, a container or stilling-chamber arranged at one side of said platform, a discharge from said container located in alinement with the upper face of the platform, in combination with means for introducing constantly-flowing water into said container below said discharge.

3. In an apparatus of the character described, a container or stilling-chamber having an outlet or discharge, a platform forming a continuation of said outlet or discharge and arranged substantially in a horizontal plane in alinement with the outlet, a freezing medium located below the platform, said container extending below the freezing medium and platform, and means for introducing constantly-flowing water into said container below the discharge therefrom, all arranged so that said water is first stilled in the container and thereafter permitted to overflow in film form therefrom upon the platform.

In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.

El) XVARD BARRATH.
