RADIATOR CONSTRUCTION.

Specification of Letters Patent.

Patented Aug. 8, 1911.

Original application filed May 3, 1909, Serial No. 493,545. Divided and this application filed July 10. 1911.

' Serial No. 637,664. 1

To all whom it may concern:

lie it known that I, VIucmiUs J. MAYO, a citizen of the United States, residing at New Haven, New Haven county, State of Connecticut, have invented certain new and useful Improvements in Radiator Construction, of which the following is a full, clear, and exact description.

1 My invention relates to a new and improved radiator construction, and this case is a division from my co-pending application, Serial No. 193,545, filed May 3rd, 1909.

The object of the invention is to provide a simple, yet strong and durable construc tion for the effective cooling of fluids, the completed structure being of particular utility when used in connection with a water cooling system for cooling internal combustion engines.

In the accompanying drawings, Figure 1 is a rear elevation partly in section of-a complete radiator constructed .to embody my invention. Fig. 1 is a vertical section on the line 1l, Fig. 1, showing the interior of the feeding chamber. Fig. 2 is anedge view of a detail. Fig. 3 is an end view of what I will term one unit of the radiator honeycomb. Fig. 3 is a similar view of a modification. Fig. 4 is a. front elevation of part of the radiator honeycomb the same being relatively enlarged, and being broken away at certain points. Fig. 5 is a section on the line 5 Fig. el. Fig. 6 is a top plan view of a group of radiator units before completion, looking down through the water passages between the same.

1 indicates a casing of any suitable form and material, the same constituting in et' fect the main frame; 2 is a teeding chamber located in the upper part of the casing 1 and into which flows the water to be cooled.

3 is the supply pipe of a water cooling svstcm.

is a distributer chamber having large number of perforations 55 therein. said distributor operating to distribute the water evenly to the upper ends of the passages wherein the water is cooled.

(L is an inlet pipe provided at the top for the purpose of permitting the water cooling system to be filled with water.

7 is a cap for the pipe 6. 8 is an overflow and ventpiue which prcferably extends partially up into the pipe 6,

the lower end passing out through the wall of the radiator at any suitable po1nt,'and

reterably leading down to a point near the bottom. This vent pine furnishes an outlet or overflow in the event an excessive amount of water is poured into the radiator and it also furnishes a vent for any steam which might accumulate in the event the water is overheated, as by overheating the engine.

.9 is a draining chamber suaced apart from the feeding chamber 2 by suitable partitions.

10 is an outlet pipe constituting part of the cooling system and which may connect the draining chamber 9 with the jacket of an engine.

The. radiator element proper, or honeycomb (the eonstruct-ion of which will be hereinafter described) connects the feeding chamber 2 with the draining or the receivF ing chamber 9, and includes a multitude of straight unobstructed upright fluid passages down through which the fluid to be cooled .ing down between them.

In Fig. 1 I have shown four tiers or blocks of assembled radiator units, each block being separated by preference, in such a way as to provide three horizontally arranged water passages communicating with all the vertical passages. The number of tiers of assembled units is immaterial in a broad sense, although for the purpose of manufacture, and in certain practice, it is preferable that there should be two or more spaced tiers dependii'ig upon the size and the particular use of the radiator. Each radiator block is made up of a number of units 11--.-11, a single unit being shownin Fig. 3. A unit. is formed by taking a strip of thin metal of suitable length, and width, and first providing therein a nuinber of plaits. These plait-s may be formed by such a machine'as set forth in my co-pending application, Serial No. 486,909. In operation this machine manipulates a strip of metal step by step in the manner shown in Fig. 2, wherein av slight ,U-shaped bend, as shown atthe left of said figure. is first formed. The next I bend to the right, though V-sliaped, ,is

sharper than the former. \Vhen the metal is in this condition, the walls of the sharper V-shaped bend are pressed tightlytogether to form a closed plait, as shown by the two plaits at the right hand end of F ig."2. The

importance of "tightly closing the plaitswill later be explained. p

'lVhen a strip of metal of the proper length is provided with a sufficient number of closed plaits, said stri is bent back upon itself, as shown at the left hand end of Fig. 3, so' as to bring the plaits into alternate registry, 'the'edgeof each plait on one wall of each unit bearing against the opposite wall of the unit so'as to support the same against collapse and steady it against vibra- The .two ends of each strip metal are preferably formedand connected tlon.

of plaited as follows: One of the ends is turned back upon itself at the base of the next to the last plait, as shown atll so as to present the open edge of the end plait in position to receive the-oppositeend 15 of the strip; In this manner the ends of the strip are locked together, see Fig. 3.

In Fig. 3 I have showna modified form of unit in construction, in which only a part of the strip is plaited, the unplaited part being doubled back as. before, so as to rest tightly against the ,edges of the plaits on the other part. In this case, the ends of the strip overlap and are soldered together at 41". When a sufficient number of units have been formed to build up a single tier for the radiator, said units'are placed in a suitable holder, and are separated or spaced apart -by meansof wires 12-12 located-close t0 thej opposite ends of said unitsections, (see Fig. 6), saidwires 12 12 spacing said units apart sufliciently to provide the vertical water passages before referred to. When the wires arein place,.each end of'each grou of unitsis d pped in a bath of solder, whic firmly bindstogether all ofsaid units,

- andthe wire spacing,elements into one substantially homogeneous structure.

between each tier,

When twoor more tiers of units are used, horizontal spacing Wires, as indicated at- 14. 14e (see Fig. 5) arepreferably provided so that when the solder is appliedias previously referred to, all of the units, together with the vertical, as Well as horizontal spacing wires, will be fipmlybound together at the front and the rear of the honeycomb, to provide both the vertical and the horizontal water pas sages. Vhen the honeycomb structure, thug. described, is finished, the same is mounted withinthe casing 1, and soldered theretoj'entirely around itsedges" in such a manner as toprevent. leakage of water, but nevertheless so as to permit the "water to freely flowentirely over-the upper endof the radiator down through thevertical pasator frame or casing." \Vhen such corners are cut away, it is obvious that in finishing up the same,- care should be observed to leave the upright water passages free and unobstructed, so that .water in the upper part of'the radiator can freely flow downthrough the upright passagesbetween all the radiator units.

I have heretofore called'attention to the importanceof'closing tightly together the two walls of each pla'it. By so doing, I ab solutely prevent dirt or foreign substance from accumulating in or adjacent to the upright water passages, for as will be seen,

were these walls left open or spaced apart,

a multitude of short horizontal shelves or pockets would thereby be formed, which would notonly retard the circulatiombutwould in a short time fill up with foreign matter to such an extent as to not only encroach upon the upright passages and thereby retard or entirely shut off circulation, but also materially retard the cooling of the plaits. Again, by folding both walls of each plait tightlyagainst each other, they stiffen the plait and afford a stronger sup. port for the opposite side wall of the'unit of which they are a part, there being less danger of collapse of the plaits by reason of the mutual reinforcement between said contacting walls. Again, by closing the walls of 'each' plait tightly together, 'a substan-' tially greater cross-sectional area is provided for the passage of air throlugh the honey-c comb than would be th'elcase if the walls of each plait were separated, inasmuch as in exact proportion to the extent that the plaits. are unnecessarily thickened, is the cross-sectional area of the air passage reduced in a. honeycomb of given sire.

The method offorming each unit, and the construction thereof, possesses superior advantages in that, by doubling a sheet-of plaited metal upon itself, it provides only one seam tobe soldered to complete a single v unit, there y greatly reducing the danger of leakage. Again, by doubling the; metal at the end of each unltback' upon itself, at the base of one plait, three thickncsses'of'metal are provided instead of. two, .which gives added stiffness and strength, so ;that;when

a number of tiers of units are-arranged a block, the end walls willbe' found to be sufficiently strong to resist the pounding tendency upon the horizontal spacing and supporting wires 14-1l.

The foregoing and other advantages will be apparent to any one skilled in this art and familiar with the use and requirements of devices of this character.
