WALTER L. WHITMAN, OF BRIDGEPORT, PENNSYLVANIA.

LAV'RD-COOLER.

SPECIFICATION forming part of Letters Patent No. 512,642, dated. January 9, 1894.

Application filed January 14, 1893.

.To all whom it may concern:

Be it known that I, WALTER L. WHITMAN, of the borough of Bridgeport, in the county of Montgomery, State of-Pennsylvania, have invented certain new and useful Improvements in Lard and Liquor Coolers; and I do hereby declare the following to be a description of the same, reference being had to the annexed drawings, making part hereof.

My invention relates to apparatus for changing the temperature of liquids, and has particular reference to that class of such devices adapted for cooling lard.

My invention consists in the construction and combination of parts as hereinafter de-' scribed and claimed.

In the drawings :-Figure 1, is a longitudinal vertical sectional view of the tanks, the other parts being in elevation; Fig. 2, a vertical cross sectional view of the tanks, showing in elevation the coil of pipe and vibrating apparatus.

A is the outer tank made of wood, sheet iron, or other desired material; B the inner tank, into which is placed the material to be treated; Othe interspace, into which is injected the liquid designed to perform part of the'function of changing the temperature of the contents of inner tank B. Thelatter is preferably made of iron plate, or thick sheet iron so as to be susceptible as a conveyer of the temperature of the liquid in space 0 to its own contents.

D is the liquid in space 0, fedfrom pipe E,

the flow being regulated by valve J; F a pipe to convey the excess of infiowing liquid from space 0 and the entrance to pipe F is located at a point at which it is desired to maintain the liquid level.

G is the material to be treated, the temperature of which it is desired to change.

H is a tank from which through nozzle and cook I the material G is supplied to tank B.

K is a coil, or series of vibrating pipes, sustained by lifts L and chains or bandsM from horizontal rod N, which latter, at the will of the operator is revolved by rod 0 and hand wheel 0. Rod 0 is connected with rod N by the universal joint P Q Q Q are lugs and joints; S sustaining guides R R R, which latter are long slotted Serial No. 458,429. (No model.)

' rods adapted to receive so much, or such parts ism, so as to permit of bending and freedom of action of the coil in its rising and lowering in guides R R R.

The operation is as follows: The tank B is charged with the matter to be treated from tank or reservoir H through nozzle and cock I. While this matter, if it is desired, can be heated, we will suppose it is desirable to cool it; because the employment of the active agents to change the temperature may go to cool or to heat such matter. Heated lard in its liquid state is supplied totank B, if it is desired to cool it. Cold water is supplied from pipe E to space 0, the overflow passing off through pipe F, continuously. Cold water is sent through pipe P, continuously, and finds its exit through pipe P. Wheel U is set in motion and, actuating one guide B, through the coil, actuates the other guides and by means of connecting rod T, vibrates the coil K laterally through the mass under treatment in tank B. Thus stirring it and cooling it within said tank by a continuous current of cooling vapor or water while the tank is conveying to the mass the cooling influence of the liquid 0 in acontinuous current. When the lard is cooled sulficiently to be set the flow of the cooling liquids is stopped by shutting off the cooks and valves controlling their flow. The hand wheel 0 is then turned to wind up the chains or bands M M, thus raising the coil K in guides R R R. When the coil is raised out of the mass treated the latter is removed from tank B by buckets, siphons, or any of the means known to ordinarily skilled mechanics, which require no special description here.

What I claim as new is-=- 1. A temperature regulator for liquids,comprising in its construction a tank, a coil or connected series of pipe, avertically movable support for said pipe, flexible connections from said coil or series to supply and discharge pipes, means for raising and lowering said support, and independent means for vibrating said coil or series of pipe and support relatively to the tank, for the purpose set forth.

2. A temperature regulator for liquids, composed of a tank, adapted to receive the liquid under treatment, a vibrating coil, or connected series of pipes,with flexible connecting tubes P P, adapted to inject and carry off the agent regulating the temperature of the contents of tank 13; vibrating mechanism R R, T U, to throw said coil from side to side of said tank, guides R R to direct the upward and downward movement of said coil; bands M M and rod or Winding agent N to take up said bands M and raise said coil from the material under treatment, substantially as described.

3. A temperatu re regulator for liquids, com- 20 posed of a tank B, adapted to reeeive the liquid under treatment; a vibrating coil or connected series of pipes, with flexible connecting tubes P P, adapted to inject and carry cit the agent regulating the temperature in 25 said coil of pipe; vibrating mechanism R R, T U, to throw said coil from side to side of tank 13; outer tank A, with an interspace between it and tank B, whereby a temperature regulating agent may be floated in said in- 30
