lower end passing out through the wall of the radiator at any suitable point and preferablyleading down to a point near the bottom.

If an excess of amount of water 'is poured into the radiator it may overflow through the pipe 8 and be conducted thence on the top of the radiator. Should steam be generated by an over hot engine, the pipe 8 furnishes a vent. I

The radiator element proper of the honeycomb (the construction of which will herein after be described) conneets chamber 2 'wlth chamber 9 and includes a multitude of straight unobstructed upright fluid passages down through which thefluid to be cooled is permitted to freely flow. The walls of these passages are 'mad'e extremely thin and are separated by horizontalair passages ..run-

" ning fore and aft through the radiator,

whereby sziid walls may be eifectively cooled water passing down between them. i i j i In Fig. 1 I have shown four tiersor blocks of assembled radiator units, each block being separated by preference from the others in such a way to provide three horizon; tally arranged y ater passages communicating with all of the vertical lwater passages. The number-of tiers of assembled units is immaterial in a broad sense, although for the purposes of manufacture and in certain practice it is preferable that there should be two or more spaced tiers, depending upon the size and the particular use of the radiator. As stated, each radiator blockis made up of a number of units arranged side by side and properly spaced and united, a single unit being shown in Fig. A unit is formed by taking a strip of thin metal of suitable length and width and first providing therein a number of plaits. These plaits may be formed by sucha machine as set forth in my United States Letters Patent No. 989,380. In operation, this machine manipulates a strip of metal step by'st-ep, as indicated in Fig. 4, where-1n a slight U- shaped bend, as shown at the left of said figure, is formed. The next bend to the right is V-shaped, while the next bend to the right, though V-shaped, is sharper than the former. When the metal is in this condition, the walls of the sharp V-shaped bend are pressed tightly together to form a closed plait, as shown by the four finished plaitsat the right hand end of Fig. 4. The importance of closing the plaits will later be explained. Not only is the metal plaited, .as previously described, but at a suitable stage in the forming of the plaits the edgesof the metal at both edges of the sheet are offset. This will be seen by referring to Figs. Land 6, wherein the metal of the main body of the strip at the base of each plait is shown as setback or offset as at 20in a direction opposite to the plait. In the same figures it will also be seen that the edge of the metal at the end ortop of the plait is offset as at 21 in an opposite direction so that when the plaits are flattened down it will be found that both edges of the stripfand both edges of each end of each plait are oflset. The purpose of offsetting the free edge of the plait, as distinguished from the edge connected to the main body of the sheet, is to provide at each end' of the plait a filler-in which operates in the manner hereinafterdescribed. When a strip of metal of the proper length is provided with a sufficient.

number of plaits, said strip is bent back upon itself, as indicated at the left hand end of Fig. 5, said bend being adjacentto the base of one of the plaits. \Vhen the strip is bent back, it will'bring the plaits into alternate registry, as shown in Fig. 5, the free edge of each plait on one wall of each unit bearing against the opposite wall of the unit so as to support the latter againstcollapse and steady it against vibration. In Figs. 5 and 6 it will also be seen that the ofi'sets at the free edge and at each end of the plaitwill fill in the space adjacent to the offset edge of the opposite wall. The free ends of each strip when folded into the form of a unit are suitably connected preferably by an interlocking joint, indicated'at 15, Fig. 5. This interlocking joint is formed by folding back one end of the strip at the base of one of the plaits near the end, excepting the end plait, which latter, whenturned back, presents its open edge outwardly to receive the opposite end of the strip, a-sin a pocket,

which latter may be soldered. Other ways,

of course, may be employed for connecting the free ends of the strip when bent up to form a unit, it being obvious that in all instances the unit is provided with only one seam, thereby greatly reducing danger of leakage. W hen a unit is thus formed, it is apparent that its opposite edges at each end flange outwardly, as shown in Fig. 6, whereby a. number of units may be placed together side by side, the flanged ends resting against each other, said flanges providing the upright water passages, clearly seen in Fig. 8. By this arrangement the unitsare spaced without the necessity of employing separate spacing devices, the use of which involvesadditional expense in that additional parts and labor are required. By providing additional parts, additional weightis provided, which, in the completed honeycomb structure, adds materially to the sired number oflunits is placed in. a proper holder and both ends, that is, the front and rear ends of the honeycomb structure, are dipped into solder which serves to firmly bind all of the units into one substantially homogeneous block. If, as shown in Fig. 1, it is desirable to arrange blocks of radiator units in spaced tiers, to insert between the ends of each tier the spacer devices I l-14 (Fig. 9), which may way, as by dipping. a horizontal water formed between the several tiers connecting all of the upright passages. lVhen a.honeycomb structure'of the proper size and shape hasbeen produced, it is fitted into the main frame 1 and securely soldered all around to prevent leakage.

1617 are partition braces which serve to separate the chamber 1 from the chamber 9 so that any water spilled in chamber 1 will be caused to run down through the passages in the honeycomb structure, wherein it is By this arrangement cooled, to and into the chamber 9.

l8-18 are trunnions for supporting the radiator.

19 is a rod or screw such ascustomarily provided to hold the top of the radiator against fore and aft movement. As hereinbefore indicated, the plaitsare not only specially formed as to swaging the opposite ends, but it is most important that the walls thereof should be pressed tightly together to prevent the possibility of the accumulation between the same of foreign matter which would tendto impair the radiation of each plait and which would also tend in time to choke of! partially or entirely the upright passages, for were the plaits left open, it is obvious that a multitude of short horizontal shelves would be formed extending entirel T across each of the upright passages and upon which lodgment for dirt or other foreign matter would be found. By

setting the free edge eaclrend of the plait to provide the filler-In extension, as preit-is merely necessary off be soldered therebetween in any desired space or passage is viousl described, I have found that the fin- I be apparent to anyone skilled (in this art and ished oneycomb structure possesses a maximum" Strength because, when the front and rear faces of the honeycomb structure are dipped into solder, there are no spaces that should be united that are left disconnected,

'aswoul'd' be the case if the top edges of each plait were straight and not, offset. By this construction, therefore, .a maximum of strength is provided which, in view of the trying use to which such devices are sub jected, guarantees a maximum of durability.

In Fig. 2 I have shown a radiator con 'structed in all respects, save one, like that shown 'in Fig. l, the single respect of difierence'being that the ra'diatorumt-s are so constructed as to form the honeycomb in a single block instead of tiers of blocks, as shown in Fig. 1. ,In this and other respects my radiator is susceptible of modification without departure from. the spirit and scope of the following claims.

v The foregoing and other advantages will familiar with the use and requirements of devices of this character.' For example, by

eliminating the necessity for separate spacers between the several units and by so constructing the units that integral ofi'sets are provided for effecting the spacing without separate spacers, a very substantial amount of material and weight is saved, an item of great importance. Again, by eliminating the necessity for separate spacing devices, a large amount of labor, such as required in inserting said separatespacing devices and holding them in place during the soldering operation, isavoided. Again, by conforming the ends of the fins or plaits so as to fill out theextra space between the side walls at the ends formed by offsetting the side walls toured, for, as is well known, it is next to impossible to bridge any substantial gap with hot solder where the article to be soldered is dipped into the molten metal, as in this case.

'VVhile I have shown my invention .in its preferred form, obviously, in various features of design and structure, it niay be modified.
