in the operation of ice making and iri 'eratin olants. in the me oritv of ca a e; l

water is used tor cooling and condensing purposes w iich holds in suspension a la ge amount of lime, magnesia and other mine matter. in passing ove the hot surfaces ot a condensing or cooling coil this mineral matter is precipitated and collects in the term of scale on the hottestsurtaces of such coils. This compels the use of condensing and cooling coils of the atmosphe'ic type, c., coils in which the cooling liquid trickles down over the outside surface of the coil, for in condensers and coolers of the inclosed or multitubular type the scale gradually in creases until the water passages are entirely closed thereby, and since this scale cannot be removed without great cost the condensers are rendered practically useless.

The purpose of my invention, therefore, is to provide an atmospliieric condensing ant cooling coil of increased etl'iciency without undue increase in cost of manufacture, and one in which the condensed fluid will be cooled to a lower temperature with the use oi a given quantity of the condensing fluid than is possible in the atmospheric condensers heretofore in use.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is an elevation of an atmospheric condenser in common use having attached thereto liquid cooling section cmbodying my said invention, Fig. a. side elevation of the improved liquid cooling section shown partly in section and. with the middle portion broken away to enable the ends to be shown on a larger scale, Figs. 3 and 4 cross sections on the dotted lines 8 and 4-l respectively in Fig. 2, looking in the direct-ion indicated by the arrows, and Fig. 5 a detailed section looking in the di- Specification of Letter l E l l EENNSYLU .1

A pipe is screwed into It and a pipe 21 into hinge erring to Fig. l, the pipe l) is joined by the fitting 22 and the pipe to the outlet fitting ot' the atmospheric condenser proper. The pipe 2 is also joined to pipe J by fitting 25. The bowl A is hollow and is provided with an opening into pipe 1.

o- A is. he I through the first two pipes 2 and 3 is carried by means of fittings B and and pipe e to the top pipe 5, and thence through the several pipes of the coil until it reaches the lower pipe (3 and titting T through which it leaves the condenser in its condensed form to other parts, not shown. The cooling fluid delivered to the bowl 1* from any source of supply and from thence enters the pipe 2 A having a slot in its top side. Said pipe is i. l -4 ii soon hlleu and the tooling mud oxeinows through the slot and trickles down over the outside surface of the pipe coils beneath.

t will be seen that the cooling thud, trichling over the outside of the coils will be warmed somewhat when it reaches pipe (3 on which the outlet fitting T is placed and i that the condensed ammonia leaving the con- 1 denser from this pipe cannot be cooled to a temperature colder than the temperature of the cooling fluid when it reaches this pipe.

When the apparatus is constructed to embody my improved liquid cooler the opera 1 tion is as follows: The condensed ammonm instead of leaving the condenser from fitting T is carried through pipe to the pipe D of said cooler from which it passes through fitting 12 to pipe C pipe C by means of pipe 20 and flows through this pipe, fittings 0 and (Z and pipe D into pipe 21 by which it is conducted to the bowl A. It ill thus be seen that the condensed ammonia in being carried through my said improved cooling section is brought into intimate contact with the cooling fluid before said cooling fluid is delivered to the warmest part of the condenser, and, further, the condensed ammonia leaves from the point at which the cooling fluid enters at its coldest temperature, and, further, that the? condensed ammonia is contained in the inside pipes or passages which are completely surrounded by passages containing the coldest cooling fiuid and no opportunity is afforded for the condensed ammonia to become warmed from the outside, therefore, the condensed ammonia will be cooled to a l l i perfectly performed. l l i l i i and is discharged through pipe to other parts, not shown. The cooling fluid first enters the i temperature at or near the coldest temperature of the cooling fluid when entering the apparatus. In this manner the condenser is rendered very etlicientand its oflice in an ice making or refrigerating plant is more It is obvious that the improved liquid cooler, as well as the ammonia condenser proper, may consist of any number of pipes or coils or sets of coils which will be best adapted to the purposes desired.

It is understood that while I have described my invention as a liquid cooler sec tion for combination with an atmospheric ammonia condensing or cooling coil, of the form above described it may be used in combination with atmospheric condensing or cooling coils of other forms and for other purposes with equal facility and efficiency and I do not therefore, confine myself to the specific form shown or any particular use but consider my invention as broad as 5 defined in the following claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is

In a condensing and cooling structure the combination of the condensing section comprising a stack of coils of pipe arranged to receive the fluid to be condensed through its lower coil, abranch leading from said lower coil to the upper coil, said coils being con nected to form a passage for said fluid from t said upper coil to the coil adjacent to said lower coil, a cooling agent distributing pipe above said stack of coils arranged to dis charge the cooling agent over the exterior of said coils, and a cooling section comprising a coil of double pipes having passages through the inside pipe and between the pipes. the inside pipe being connected at its top with the discharge end of the condensing coil and at its lower end with a pipe leading to a receiver, and the outside pipe being connected at its lower end with the cooling agent supply and at its top with a pipe leading to discharge into the condenser cooling agent distributing pipe, substantially as set forth.

In witness whereof, I, have hereunto setmy hand and seal at lvaynesboro, Pennsylvania this second day of May, A. D. nineteen hundred and five.
