Application led Tune 3, 1897. Serial No. 639,234. (No model.)

To @ZZ whom it may concern.-

Be it known that LOTTO MErNsHAUsEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful lmprovement in Liquid-Cooling Apparatus, of which the following is a specification.

My invention relates to liquid-cooling apparatus in which the liquid to becooled is caused to'flow an extended course through a conduit in one direction, the said conduit being surrounded by or surrounding a second conduit, through which a cooling fluid is caused to flow.

While my invention may be employed for cooling any kind of liquid, it is intended more especially for use as a beer or wort cooler.

My object is to provide apparatus of improved construction in which the liquid to be cooled travels an extended course in one directio under the chilling infiuence of a cooling iuid flowing in the opposite direction, the apparatus being particularly compact and effective in operation and at the same time easy to clean.

In thev drawings, Figure l is a broken end view in the nature of a diagram of wort-cooling apparatus of my improved construction; Fig. 2, au enlarged broken longitudinal section taken 'on line 2 of Fig. l and showing one of the series of cooling devices;v and Figs. 3 and 4, sections taken, respectively, on lines 3 and 4 of Fig. 2.

A A are cooling devices, all of which are constructed as shown in detail in Figs. 2, 3, and 4. Each device A is formed with an outer shell comprising a central cylinder t, end cylinders sr, and heads q p. In. the head p is a cleaning-opening p', over which ts a cap-plate p2, held in place by a flanged ring p3, rendering the opening gas-tight. Fitting between the cylinders fr t is a diaphragm fn., having a circumferential flange W, at which it is secured between anges on the said cylinders. The diaphragm n is formed with a central tubular extension n2, having an end n3, provided with a comparatively large central opening n4, surrounded by a series of smaller openings W5. AOn opposite sides of the tubular portion 'n2 and formed integral with the diaphragm are .passages n, extending from the flanged face of the diaphragm nearly to the opposite end of the space surrounded bythe tubular extension n2. The flange n within the cylinder is provided on opposite sides of the passages n@ with a series of openings m7. yExtending through a stuffing-box qrin the head q is a pipe m, rendered flaring on the inner side of the cylinder and there provided with an outer circumferential shoulder m and an end plate m2, which latter is provided with a series of openings corresponding with the openings n4 a5 in the diaphragm fn. In the cylinder is a sleeve Z, provided at one end with a ange Z', at which it is fastened between adjacent flanges on the shell-sections Z s. At its opposite end the sleeve Z fits tightly over the annular. shoulder m of the pipe m. one end in the tubular section ft2 and at its opposite end passes through the sleeve Zand fits over the shoulder m, all the joints being tight. Within the inner cylinder is a central pipe lo', surrounded bya series of smaller pipes k2. The pipe Zt at one end is fastened in the opening n4 of the diaphragm and at its opposite end is fastened in the corresponding opening in the plate fm2. The pipes 7a2 are fastened at one end in the openings n.5 of the diaphragm and at their opposite ends in the corresponding openings in the plate fm2. Between the innercylinder Za and outer shell is a series of pipes t, fastened at one end in the openings a7 in the flange n' and fastened at their opposite ends in corresponding openings Z2 in the iiange Z.

Extending into the shell-section t is a pipe or conduit B. B is a pipe or conduit extending through the shell-section s and into the cylinder Zo, thus communicating with the interior of the latter. C is a pipe or conduit extending through the shell-section s only. The interior of the shell, it will be understood, is separated by the internal walls into chambers or compartments .fr as y y. The chamber .fr surrounds the inner cylinder, and the chamber x surrounds the pipes Zo k2 in the inner cylinder. The said two chambers communicate through the passages n. The chambers y 'y' are at opposite end portions of the shell and communicate with each other through the pipes e'.

The wort or beer to be cooled enters through the pipe m and passes through the pipes Zo k2 An inner cylinder 7c fits at IOO to what I term the primary end chamber y. From the chambery it passes through the pipes t' to what I term the secondary end chamber y, whence it escapes through the pipe C. The cooling iluid enters at B, iilling the chamber it, surrounding the inner cylinder, and enveloping the pipes i. From the chamber x the cooling fluid iows through the passages a6 to the chamber fr', where it envelops the pipes lo 7a2, escaping through the pipe B. The wort or beer as it enters the device is acted upon by the cooling liquid just escaping from the device, and as it flows to the outlet C the wort or beer is subjected to the cooling influence of the cooling Huid which has just entered the device.

Tort or beer to produce the best results in the iinal product should be cooled more or less gradually and should not be subjected to a too sudden chilling. For this reason, and also to obtain the best results from the cooling fluid, it is advisable to cause the beer or wort to be acted upon at first by the cooling iuid after the latter has absorbed heat and iinally by the cooling` iluid at its lowest temperature.

My aim in devising the present device has been to render it as compact as possible and at the same time cause the beer or wort to pursue the longest possible course under the influence of the cooling Huid, at the same time permitting the device to be readily cleaned when desired.

Then it is desired to clean the device, the plate p2 should be removed to permit a suitable pipe-cleaner to be passed back and forth through the pipes k', 7a2, and i. The chamber @j may be readily cleaned at the same time and the chamber fg may be flushed out or scrubbed, in which latter event the head q may be removed to give more ready access to the chamber y'.

In Fig. l I have shown my devices coupled together in series below a hop-jack D. The wort enters the first device through a pipe D, passing thence through the pipe C to the next device to the end of the iirst or upper seriesv of devices, from the' last of which it passes downward through a pipe C to the first of a second series of cooling devices A. From and bring the wort down to the desired low temperature. The course of the wort is such that initially its temperature is iniluenced by water comparatively warm and finally by ammonia-gas at the lowest temperature which it is desirable to employ.

Vhile I prefer to construct my improved apparatus in all its details as shown and described, the construction may be modiiied without departing from the spirit of my invention as deiined by the claims.

lVhat I claim as new, and desire to secure by Letters Patent, is-

l. In a liquid-cooler, the combination of a shell, an inner cylinder and inner walls forming together primary and secondary end chambers and intermediate and intercomuninicating concentric chambers, a conduit eX- tending into one end of the shell, a series of straight and parallel pipes extending from said conduit through the inner intermediate chamber to the primary end chamber, a series of straight and parallel pipes extending from one end chamber to the other through the outer intermediate chamber, a conduit communicating with the secondary end chamber, and conduits communicating respectively with the inner and outer intermediate chambers, substantially as and for the purpose set forth.

2. In a liquid-cooler, the combination of the outer shell, inner cylinder 7o and inner cylinder ends Z u forming together end chambers y y and intermediate concentric chambers fr a conduit m at one end of the shell, pipes k 7a2 extending from said conduit through the chamberm to the chambery, pipes t' extending between the chambers y y', through the chamber ce, and conduits communicating respectively with the chambers @c and y', all constructed and arranged to operate, substantially as described.
