IChlm.

This invention relates to condensers.

The object of the invention is to provide a condenser particularly adapted for condensing the vapors of a solvent used for extracting cafg feine from coiee and for other similar purposes.

'With this and other objects in view which `will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction. as hereinafter described and claimed, it being undery stood that changes in the details of the inven tion and in the combination of parts may be made within the scope of the claim without de parting :trom the spirit of the invention.

,In the accompanying drawings forming part of this specification,

Figure l is a perspective view of the improved .condenser, part of the tank of which is broken away to show the elements Within.

Figure 2 is a View o one ci' the six condensing chambers shown in Figure if Figure 3 is a detailed view in vertical section on the line 3--3 or Figure 2, showing a portion of the condensation chambers.

Figure 4 is a detailed plan View oi' the overow from the cooling tank.

Generally described, the condenser of this in.- vention includes a cooling tank i into the lower portion of one end oi which, cold water is introduced through a pipe 2.

The Water is jetted vertically upward from the water inlet 2 through a series of jets 3. The ca pacity of the pipe 2 is sufficient to feed ali oi the Arranged in the cooling tank i are six condensation chambers i-t which extend lengthwise ci the tank as indicated in Figure l and are spaced away from each other.

The arrangement of jets 3 relatively to the water inlet 2 is such that two of said jets are on opposite sides of each of the condensation chambers l, as clearly shown in Figure 1, and said jets as indicated in Figure l are set slightly inward from the ends of the condensation chambers so that the cold water is jetted upward on both sides of each of the condensation chambers. y

The cooling water in the tank continuously ows through the pipe 2, jets 3 and out of the tank at the opposite end through the overow pipe 5 which maintains constant level of cooling water in the tank.

By locating the cold water inlet 2 at one end of the tank and the overflow 5 at the other end of the tank and by directing the jets 3 upwardly, the cold water rst passes upwardly in the tank i and then flows towards the bottom and the overow pipe 5 constantly drains ci! the warmer strata of water at the top.

The tank l preferably is made of wood supported on beams and when the appara- G tus is not in use the water may be drained from the tank i through the drain pipe 1. The condensation t. i-l are suitably supported upon sleepers or cross-bars B t as shown in Figure 1. I

The solvent whidh has bn employed :for leaching or extracting the codeine from the coffee or other duid to be acted upon, is vaporized and enters the apparatus through an enlarged vapor header Si, which extends transversely across 1d the top of the tank i and is connected with all of the condensation chambers M by means of the down pipes it-i@, each ci which extends through a flared inlet portion ii into one of the condensation ch w t.

The condensate passes out from the bottom of each, oi the condensation chambers t through a ared outlet i2, into an outlet it which extends into a main outlet it, which extends transversely oi the tank i. Each ci the outlet pipes i3 and the inlet 'pipes i@ are in tvvo sections suitably joined together by ange joints i5, which are staggered as indicated in Figure 1, so as not to interfere with each other and yet permit ready access for assembling or disassembling the tanks.'

As shown in Figures i and 3, each of the con densation chambers has extended transversely across it a series of stainless steel rivets or tubes it, which serve to reinorce and strengthen the condensation chambers.

Each of the condensation chambers, as shown in Figure l, is provided with alternating bade partitions which are marked from the top down-- ward as i'i, it, mdd, 2i, 22. A

it will be observed that the partitions il, it and 2i are placed immediately above the rivets i6 so as to m reinforced thereby. I t will be further observed that each'of the partitions numbered ii, it and 2i extend from the center of the tank in opposite directions, and downwardly sloping to a point spaced away from the ends of the t.

It will also be observed that the partitions i8, 2&3 and 22 are connected with the ends of the tank and extend inwardly and downwardly to a point spaced away from the center of the tank.

It will further be observed that when the vapor enters each of the condensation chambers 4 at the point ii, itpasses through a restricted space dened by partition I'l and the top of the tank l,

and that the gas then expands out into a wider space produced by the down incline of the partition I1 at each end.

It will also be observed that any liquid which condenses on the partition i1 tends to drip from the opposite ends thereof in the form of a cascade through which the gas man at the restricted point formedv by the partitions Il and I8. and the gas then down at the center through the opening in the partition it, and then repeats the same course in d to am.' tions I9, 2t, 2i and 28. n

It will be further noted, from Figure 1 that the bottom d a of each condensation tank is sloped on the incline tow the outlet pipes i3 so as to permit the condensate to ofw into the outlet i4.

IWhat is claimed as new is:

In a condenser, a tank provided with an overflow outlet for cooling water and containing a. plurality of closely and parallelly spaced hollow, hat, relatively thin, vertically disposed vapor condensing units arranged in parallel and located below said overow outlet, vapor inlet means for each of said condensing units, condensate outlet means for each of said condensing units, cooling water inlet means in said tank disposed adjacent the bottom of said tank and having inlet jets on each side of each of said condensing units, which jets are adapted to-jet the incoming water onto the sides of said condensing units'.
