IMPROVED APPARATUS FOR COOLING MALT LIQUORS.

Specification forming part of Letters Patent No. 59,336, dated November 6, 1866.

To all whom it may concern:

Be it known th at I, WILLIAM ALLENDEREF, of the city of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Cooling Apparatus for Malt Liquors; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, and to the igures and letters of reference marked thereon.

My invention relates to that class ot' cooling apparatus in which the liquid to be cooled is made to flow overthe outer surface of a series of pipes, which are alternately so connected` at the ends as to form a continuous circuit or channel for the cooling medium-ice or springwater.

The nature of my. improvement consists in making use of outer tubes of larger diameter than those heretofore employed, and inserting` into these tubes others of smaller diameter, which are closed at both ends, and so arranged as to compel the cooling-water to pass through the narrow annular space between the outer and inner pipe; the main object being' to produce an apparatus which shall combine great cooling efficiency with few sections of Ipipes and a reduced number of end joints.

Another important feature of this improvement consists in its peculiar applicability for reversing' the usual method of cooling by passing the malt liquor to be cooled through the narrow annular space between the outer and inner pipes and applying the cooling medium outside, which has marked advantages for certain kinds of maltliquors that have a great tendency for frothing when passed over the outside ot' the pipes. This difficulty and the consequent losses in quantity and qualityv of the liquor are avoided by the above method of cooling, and the narrow space between the outer and inner pipes spreads the'liquor in a thin sheet overa large surface, and allows the cooling medium to act upon it in a very efficient manner.

In order that my said invention maybe fully understood, 1 will now proceed more particularly to describe the construction and operation of the same.

On reference to the drawings making part ot this specification, and in which like letters of reference allude to similar parts throughout the several views, Figure 1 is a sectional side View of my improved cooler. Fig. 2 is an end view of the same; and Fig. 3 is an end section through the line A B, Fig. 1.

C C are the outside pipes, lying horizontally one above the other, and connected by shortV vertical end pieces, D D. t

The inside pipes, E E, are closed at both ends, as seen at Fig. 1, and have at one end a s/mall knob-handle, a, by means of which they can be withdrawn for cleaning, and to this end the pipes C C are provided with detachable head-pieces b b.

In order to produce a uniformly narrow space between the outer and inner pipes, the latter are, near both ends, fitted with the strips c c, which project a uniform height above the outer surface of the pipes E E and t the -inner diameter of pipes G C.

F and G are curved pipe-elbows, itted to the top and bottom pipes, and, when the apparatus is used in the heretotbre-practiced manner, F serves as induction-pipe for the cooling medium, which flows upward through the series of pipes and has its outlet at G. For this method of cooling, the usual distributingtrough H, with perforated bottom and perforated inner vessel, I, is provided; also a re- Ceiver, J, at the bottom.

d d are the distributing-strips, provided 'on the under side of the pipes C G, for conducting the liquor in a thin evenilm or sheet from one pipe to the next lower one.

Whenthis method of cooling is reversed and the malt liquor to be cooled is conducted through the pipes, as before stated, then the whole apparatus may be placed in an inclined or horizontal position and the pipes surrounded by the cooling medium in any most convenient manner; but when placed vertically, as shown in the drawings, the trough H canbe readily used to conduct the cold water to the outside of the pipes C C.

The whole apparatus is suspended within the two uprights K K, as fully shown in the drawings.

Having thus described the nature and use of my improvement, what I claim as my iuranged substantially as described in the forevention, and desire to secure by Letters Patgoing specification, und for the purpose specient, ised.
