To all whom t may concern.' I

Be it known that I, JAY G. HUNTER, a citizen of the United States, .residing at Sabula, in the county of `Jackson and State. of Iowa, have inventedl certain new and useful Improvements in] Condensers, of which the following isa description.

My invention belongs to that general class of devices known as eondensers, and particularly a condenser for use in connection with refrigerating systems. The invention has among its objects the production of a device of the kind described that is simple,` convenient, compact, durable, eflicient and satisfactory for use'whereverfound applicable. It has among its further objects the production of a device of the kind described which consists of a. minimumof parts and which is constructed with such simplicity that the same will not easily get out of order or become inoperative. VMany other objects and advantages will be obvious to those skilled in the art from the disclosure herein viven. e ro this end my invention consists inthe novel construction, arrangement andcombination of parts hereinV shownland .def scribed, and more particularly 'pointedout in the claims. a

In the drawings, wherein like reference characters indicate like or corresponding parts,

Fig. 1 1s a .sectional view.`r onem form ofmy device; Fig. 2 is a cross sectional .view taken substantially on line' 2--2 of Fig. 1; f Y' Fig is a sectional view similar to Fig. 1of a slightly .modified construction;V and Fig. a is asectional viewiof another con- Referring to Figs. and 2, it maybe mentioned that I have not considered it necessary to illustrate Ythe compressor,accumu-y lator, coils andv other parts of therefrigen ator system used `in connection with my condenser. I f

The condenser consistsl of an outer shell or casing 1, providedwithasuitable bottom 2 and top or closure 3,7the top being secured in place inV any desired manner. Within the casing 1 is an inner wall t'spaced therefrom to provide' the space 5, the relative proportions of the casing-1 and inner part 4 being such as may! be'desirecb` I have shown the bottom formed as at 6 -onjthfe interior of the part 4 with an opening 7 atthe i bottom, which is normally closedby a plate secured in place by bolts 9 or their equiva! lents. ,TWhen' so constructedl I, preferably employ a packingring 10 between the parts so as to prevent leakage, the outer casing lv with its top and bottom lbeing lso constructed Vwith an intake pipe 13 and witha discharge pipe l14. Connected with thecondenser, as shown extending through the cover plateV 3',

is an intake .pipe 15 which is connected with the compressor or the .lilze,'. and. through which the vgas is admitted to thecondenser; Pipe 1 5 is connected withthepipe 16, preferably having an up-turned end'll at the out let of'whichis arranged a checlrvalve 18Y 'or the equivalenti yI prefer to provide what might be termed a cage 19 about the end of thefpipe, the samef having discharge openings 2O through the walls thereof,r The con-A denser is connected with 'the refrigerating system,- as for; example with accumulator, by

means ofa pipe 21 or its equivalent. 4In thisconnecti'on it will be noted that the pipe 21'communicates with the space 5,! the said pipe being arranged adjacent buta little above the bottom -2 of the i condenser. drain pipe v22 also communicates withy the bottom of the space so that thespace may be drained.' ,A drainV pipe 23 isv also pro-V vided for thejinnerrpartl, s o that by means of thetwo drain pipes all ofthe' liquid may i' be drained from thecondense'r- An oil'discharge pipev 24 is preferablyfarranged as shown, as well as an outlet pipe"25which is normally closedyexcept at such `times asxit medium from the compressor.

In the construction shownin Fig. 3 31 represents a vtank or shelliWithi-n Which is:

arranged an inner tank 32,; About the inner tank 32 is provided a coil '33 which is connected with pipe 34 connected with pipe 36 extending from the compressor. However, the `check valve u35 is preferably provided 'so that` the gas` cannot -iiow` back, to

the'co'mpresso'r after it has once passed the valve. The coil 33 is connected by means of pipe 37 with thel interior or chamber 3S orv the ankBZ, `vhich tank is provided With an outletf or discharge pipeV 89 extending` to the;

accumulator or otherqdesired part oit` the regtrigeratingsystem. Tanlol is provided vvit'h water or "cooling medium intake pipe 41 'and vdischarge pipe 42 drain 'pipes 40 and 43Tbei1igpreterably arranged ,substanmuy as Shown. Y Y y Inihe A co'ns'truction' shown in Fig. 4, 44'
