iMiRovEMENT in sKATlNe-mnke.

Specification formingpart of Letters Patent No. 187,59, dated February 20, 1877; application filed January 27, 1877.

To all whom tt ma/y concern:

Be it known that I, EMIL BRGIN, now of the city, county, and State of New York, a citizen of the Republic of Switzerland, am the inventor of certain Improvements in Artificial-Ice Skating-Rinks, of which the following is a specilication, reference being had to the drawings, forming part thereof', in which- Figure l is a perspective view of the rink, on a small scale, embodying or representing my invention. Fig. 2 is a cross-section of the lsame on line w Fig. l. Fig. 3 is an end view of the corrugated sheet, showing the corrugations made angularly; and Fig. 4 is also an end view ot' thev corrugated sheet, showing the corrugations made curved.

My invention relates to -skatingrinks. in which the ice is produced by artilicial means; and consists in a rink constructed with a floor, underlying the ice and overlying the refrigerating-reservoir, that is composed ot' corrugated metal, in the manner hereinafter particularly described.

A is a tank or basin of suitable dimensions for a skating-rink-length, depth, and breadth-to hcld the refrigerating-iiuid by which the artificial ice of the rink is to be produced. lThis is to be made, of course, water-tight, ard, preferably of some material that shall have but little heat-conducting property.l B is a ioor or foundation of sheet metal, that is laid down upon the oor of the tank A. It is curved upward at each edge, ot' two sides, a and b, and is also either curved, as the two other sides or ends, or is furnished with side-or inner walls, as shown in the drawings, so ,that the whole shall form a shallow water-tank or receptacle for the water which is to form the ice in the rink. This sheet is to be corrugated, as represented in the drawings, the corrugations running from one curved edge to the opposite ones, and they may be either angular, as shown in Fig. 3, or curved, as shown in Fig. 4, or in any other analogous form. As is evident, these corrugations form, as the sheet is laid on the bottom of the tank, channels through which water may flow from one side of the tank to the other, while the lower angle or curve of the corrugation rests on the bottom of the C is a pipe for inducting the refrigerating'- uid,into the tank, and leads into the horizontal pipe D, through which and the branches c c cc the said liuid is distributed through the whole length of the tank, and is discharged into it at one side, between the curved edge ot' the corrugated plate B and the wall of the tank. E is a gutter or conductor arranged on the opposite side of the rink from the pipe O, and so placed as to receive and lead away the refrigerating-tluid as it overows from the tank.

The door ot' the tank on theside next the gutter is raised somewhat, as shown at F, and the elevation at this line should be sufticient to insure the complete lling of the channels underneath the plate B, made by the corrugat-ions of said plate. rlhe gutter E leads into a discharge-pipe or a reservoir, G, from which it is intended the fluid, after having passed through the tank and discharged its ofiice ot' refrigerating, shall be pumped into a refrigerating apparatus, to be there cooled, and then returned through the pipe C,

conductor D, again into the tank.

Any known apparatus for producing artilicial cold may be employed to refrigerate the said duid.

The water to form the ice of the rink is to be introduced in any suitable way into the rink and allowed to overflow the upper surface ofthe plate B, and should be ot' suflicient depth to lill the corrugations and extend somewhat above the upper angles or curves ot' the same.

The refrigerating-iuid may be 'salt water, or glycerine water, or any tluid which is congealed at a much lower temperature than water itself, so that when such iiuid of lower temperature is brought into contact with the lower surface oi' the bed or plate B, it will conduct away the heat ot the water lying on said plates, and thereby congeal it.

rihe advantages of a corrugated hed-plate or tloor underlying the ice, and on which it is formed, are obvious. It may permit a free, uninterrupted tlow ot' the refrigerating-luid beneath it, and allows the said iiuid to come into contact with the whole under surface of said plate or iioor, excepting just along the line where the lower angles or curves rest on In a skating-rink, the tank A, the corrugated bed-plate B, and suitable inlet and outlet fluid-cond actors, all constructed and combined to operate substantially as described.

Witness my hand this 22d day of January,

EMIL BRGIN.
