Specification forming part of`.Letters Patent No. 150,477, dated May 5, 1874; application filed i October Q0, 1873.
To all whom it may concern: i A
Be it known that I, SAMUEL B. MARTIN, of San Francisco, in the county of San Francisco and State of California, have invented an Improved Process and Apparatus for the Manufacture of Ice and other like purposes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and -to the letters of reference marked thereon.
tion with sides of tanks removed. Fig. 2 is a transverse view of the double condensing-pipe of the coil.
My apparatus consists of a supply-tank, A, above, and a shallow tank, B, underneath, the refrigerating-coil of pipes, and also a tank, C, of like description under the condensing-coil D. The congealer or refrigerator E is composed of a coil of pipes of graduated diameter, that nearest to the top being the smallest in diameter, and4 extends to the point a, from whence it connects with a pipe of greater diameter to the point al, from thence still larger to the point of connection a2, from which point the size is maintained, forming one or more coils upon the bottom of the tank, and passing to the pump F. The upper end of this coil passes down through the bottom of the tank to the receiver G. By-thus constructing the congealer-coil of pipes of different sizes, it is intended to equalize the flow of gas and liquid throughout thecoil by providing room for the expansion of the gas, which follows from contact with the temperature of the water to be This agent cooled or frozen, and thereby effect a uniform temperature over all parts of the coil. In the center of this goil is an upright post, b, on the top of which is placed a wheel, b1, which, by means of water from the tank A through a pipe, c, impinging lupon the radial vertical arms b2, causes it to rotate and carry with it a pipe, cl, having a crescent-shaped sprinkler,
cl, whereby Water is caused to ow out and .one above described. This wheel derives its supply of water from the tank B through the pipe f, which passes up through the innerpipe of the double condensing-coil and the pipe e upon the Wheel, which causes it to rotate, and expel the refrigerated Water from the tank upon the said coil through the pipe f. This water, being of stilll ower temperature than when leaving the tank A, may be conveyed back to the tank to be used over again.
In ope-rating my machine, the refrigerating or congealer coil is charged with a volatile uidorgasfromaretort. `(Notshown.) Themachinery and pump being put in motion, the vapor is drawn through the coil E by the pump F, and forced out through pipe ginto the double condensing-coil, through which it passes to the receiver G,'Which it entersin aliquid state. When a sufficient charge of the liquid is accumulated in the receiver-say, to the extent of abouttwo-thirds of the capacity-cock j being opened, the liquid flows through pipe h to the .refrigerating-coil, is there vaporized, extracting heat from the Water flowing over vthe coil, and is again returned in the same manner, and liquelied, as before, for use continuously. When it is desired to loosen the ice formed on the congealer-coil, it is only neces- .saryfto open the cock Z on pipe rlhis allows the warm gas to pass into the congealer-coil under the high pressure of the condenser, when, by Working the pump slowly, the object will soon be accomplished, and the ice, after being divided into blocks of the size desired, may be removed.
Having thus described my invention, What I clailn as new, and desire to secure by Letters Patent, is-
1. The congealer E, consisting of a coil of pipes gradually increasing in diameter, to permit the expansion of freezing liquid into gas, substantially as described.
2. The congealer E, and the spraying apparatus d d', combined and arranged as described, for the purpose set forth.
3. The combination of the tank B and pipe 'y f with the condenser D, Wheel b4, and pipe f', j
the parts being so arranged thatthe refrigersurplus water to assist in the condensation of the gas, as described.
In Witness whereof hand and seal.
