PATENT oFFIoE WATE Ft-C OQLER. f

v T 0 all whom, it pea/y concerm' States, residing at Indianapolis,in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Water-Coolers, of which the following is a specification.

This invention relates to improvements in apparatus for cooling water, and is here shown as ap water used surrounding the parts of an explosive-engine that become commonly heated during the operations of such engines aii'd in the drawings is shown as used for cooling the gasoleneengine of"an" autom'obil ebut it is not desired to limit itft'o ai'itoriiobile construction nor to engine construction. It is desired to include all uses to which the invention-is applicable. I j

The object of the invention'is' to conduct the heated water through conduits which will havethe largest obtainable'surface exposed to the air'for the purpose of cooling the water'contained within said conduits.

A further object of the invention is to provide a simple, compact, durable,- and inexpensive apparatus and one that be easy to operate and .to keep in repair.

We accomplish the objects of our invention the mechanism illustrated in the accompanying drawings, in which- F ure 1 is a perspective view of an automob e, provided with our improved watercoolin apv aratus; --Fig. 2 is a front elevation 0 sai apparatus. Fig. 3 is alongitudi- Fig. 4 is a side elevation of our invention, showing the upin cross-section.

air-tube passing therethrough, the'walls' of which are funnel-shaped. Fig. 11 is a detail showing one of the cooling-pipes on a larger scale than the other figures of the drawings, the view being in vertical section on the line 11 11 of Fig. 12, andFig. 12 is avertical s-ec-.

tion on the line-12 12 of Fig. 11.

Like characters of reference indicate like parts throughout the several views of the draw ngs.

Referring to the drawings, 10 is thebase of our cooling apparatus, and is here shown as a rectangular sheet-metal box, with a sheetme'tal cover 14, preferably of copper. This box is divided into two compartments 11 and 12 by means ofthe partition 1?, which 4: prevents direct communication I between.

As shown in Fig. 5, the.

said compartments.

sheet-metal cover 14 is provided with. a

lar e number of perforations 16, each of which are long and narrow, as shown, and

are arranged in a series of staggered rows. u A tube 17, one for each open1ng,'is secured in said water-tight joint with plate 14.. These perforations in a manner to provide a' tubes 17 are flattened, as shown in Fig. 6, so

that the opening through them presents a long and narrow space for purposeswhich will be hereinafter explained. The plate 14, which forms the cover to the above-described box, main portion of the portion in which the tubes 17' his portion includes the side plates 18, which support the top metal form ,withtheir related parts, tubes 17, which is open at rear. 14 is a second frame 19, which gives strength,

and rigidity to the construction; This.

frame 19 has the dowel-pins 20, which pins are provided with transverse slots in aliuemerit, for the several pins to receive a key,

.which will be driven therein after the parts,

are assembled for the purpose of looking together and securing said parts;

frame 19 ,and, a casing foijfthe. both front. and-. 3.; Between the bottom box and its cover also forms the bottom of the central or water-cooler, being that are located-1 Supported upon the top frame 19 isthe cap 23;,which has a top, as shown as curved in the drawingabut which maybe of any desired'shape and is closed at front dowel-pins 20 previously i described, which sameurpose. 27"is a metal plate,

p a nd'back to form a water-tighthollow structure. This.

cap will have dowel-pins 25, similar to the. a

. suitable, removable closure.

23 and top frame 19, so as to form a gasket to make a tight oint between the parts. The flattened tubes 17 will pass through this plate 27 and will make a water-tight joint therewith. The open ends of tubes 17 will -communicate at their tops with the interior partments of cap23 is the pipe 33, which is perforated at frequent intervals throughout its length, and connecting with said pipe 33 is the pipe 37, which is connected with the wateracket of a gasolene-engine or any other sizipply from which water isobtained in a heate condition and which is to be cooled. This water entering through pipe 37 is discharged through the perforations in pipe 33 into the hollow interior of cap 23 and is carried through tubes 17 down into the compart-. ments 11 and 12 in the b )x at the base.

39 is a pipe which takes from compartment 12 and discharges the cooled water backinto the Water-jacket of the engine or whatever is to be supplied. The purpose of the partitions 13 and 31 is to divide their respective vessels into coinpartmen s, which will prevent the flow of the water longitudinally of said vessels, thereby compelling it topass back and forth on a longer travel through the series of coolingtubes 17. Thus water supplied through tube 37 will pass down into compartment 11 through those tubes 17 that have their inlets between the partition 31 and adjacent end of the cap 23, and, the water from compartment 11 will pass up to the 'cap on the other side of partition 31 through those tubes 17 that have their inlets between the mouths of the first set and a partition 13,

'l and the water thus delivered to the cap 23 from the' cap into the compartment 12,v 5,

and

through said tubes 17 is carried'down again through the tubes 17, that have their discharge-openings into said compartment 12,

our the atter compartment the water which has been thus subjected to the cooling action of the air bathing the outside of the tubes 17 is carried off for use through pipe 39. By flattening the tubes, as shown and previously described, a very thin column of water is carried through them, and this column is exposed to the largest possible cooling action of the air passing or surrounding said tube. In order to retard the flow of the water through tubes 17, their discharge ends may be contracted by pressing their walls closer together, as shown in Fig. 8.

42 are a series of pipes extending trans- 'water-discharge pipe taking water versely through the cap 23 and the compartments 11 and 120i the base. These pipes are open to atmosphere at both ends and provide air-conduits through their respective chambers for the cooling of the water contained in said chambers by the flow of air through said pipes 42. r

47 represents a tubular opening through the base for the insertion of the startingcrank of an automobile and has nothing whatever to do with the operation'of our cooler proper.

Our invention is capable of various modifi cations and variations in construction with out departing from the spirit of the invention, and we do not therefore desire-to limit our selves to the exact construction shown, nor do we desire to be understood as limiting our invention to automobiles or to the cooling of explosive-engines;but i What we'do claim as new; and wish to see cure by Letters Patent of the United States,-
