JOHN FEDDEBS, 0F BUFFALO, NEW YORK, ASSIGNOB TO THEODORE O. FEDDERS,

RADIATOR.

To all whom it may concern:

Be it known that I, JOHN M. Fnnonus, a citizen of the United States, residing at .Bufl'alo, in the county of Erie and State of New. York, have invented new and use ful Improvements in Radiators, of which the following is a s 'ecification.

This invention re ates to that class of radiators which are more particularly de si ed for cooling the water which is cir-- which is' not liable to leak when in use, and

which may be constructed of strips of sheet metal so that two adjacent strips form a unit and produce a plurality of air tubes and still give theradiator as a whole the ap earance of being constructed of individua air;

tubes. 7 I

1n the accompanying drawings consisting of 2 sheets: Figure I is a fragmentary front mentary vertical section in line 77, Fig. 5. Figs. 8 and 9 are fragmentary perspective views of the two sections constitulingone of the units of the radiator core. Fig. 10

isu similar view of the plaited section of a radiator unit viewed from the side opposite to that shown in Fig. 9.

Similar characters of reference indicate corresponding parts throughout the several views. 7

In its general organization my improved radiator comprises an upper inlet header or water box 1 to which the water conducted "in any suitable way from the part which Specification of Letters Patent.

structed to form a plurality of vertical sinu one water passages 5 which open at their upper and lower ends into the lower part of the upper header and into the upper part or the lower header, respectively, and a plurality of horizontal air tubes 6 extending foreand aft of the radiator.

The headers of the radiator may be of any suitable and well known construction but the core embodies my im rovements and is constructed as follows: s a whole the core comprises a plurality of units each of the units being arranged vertically and the several units being arranged horizontally side by side so as to form a plurality of vertical sinuous or tortuous water passages between adjacent units and a vertical row or ,tier of horizontal air tubes within each unit.

Each of the core units is constructed of two sections of sheet metal, preferably cop per. One of these sections is formed of a strip of such metal, so as to produce a pinrality of fiat upright webs 7 which are ar ranged, one above the other and vertically in line, outwardly off set spacing beadsS arranged vertically, adjacent to the front andrear edges of the flat webs, a plurality of horizontal longitudinal locking heads 9 each of which is arranged between two adjacent fiat webs 7 and has its convex side arranged on the outer side of the respective strip of metal, and a plurality of alining beads 10 each of wh hh is arran ed. on the outer or convex sid of one of t e spacing beads in line with 0' adjacent locking bead and has its conve side on the outer side of the respective strip of metal. The other section of each core unit is also constructed from a strip offsuch metal so as to produce a plurality of horizontal longitudinal plaits l1 which/are arranged one above the other in a vertical tier, the inner parts or ends of the plies of each plait forming the crown thereof being connected with each other, and the outer edges of the opposing plies of two adjacent plaits being connected by an upright web which is constructed to form llat vertical portions 12 arranged at opposite ends of this web and at right angles to the plaits, a flat upright stiffening part 13 arranged at the center of this web, two main curved web portions lei arranged on oppoite sides of the fiatcentral part 13 and S aving their convex sides facing outwardly,

and two shallow seats or recesses formed 1 i passes from theupper header down throu h.

. between the outer edges of the two plies of l the several tortuous passages between e the plait so as to face outwardly with its concave side and each seat being arranged between the adjacent vertical flat end portions 12 of two webs of the plaited section and the curved intermediate portions 14 thereof.

In assembling the two sections of each core unit the same are arranged vertically side by side and the inner edges or crowns of the 'plaits 20 of the plaited section are engaged with the concave sides of the longitudinal locking beads 9 of the beaded section, thereby producing a plurality of horizontal longitudinal air passages between the twosections of the unit. After the two sections of a. unit have been thus assembled a line or streak of solder is applied to the joints between the uppermost and the low ermost plaits and their coin anion locking beads, for the purpose 0 sealing the unit against leakage of water at these places and also to prevent longitudinal horizontal displacement of the unit sections relatively to each other while assembling the radiator and also while the same is in use. In assembling a plurality of such units the alining beads of the beaded. section of each unit engage with the alining seats [50? the laited section of an adjacent unit assncwn in Figs. 2, 4, 5 and 7, thereby holding the sections of adjacent units against longitudinal horizontal displacement relatively to each other both while assembling the parts of the radiator and also while the same is in use.

When the several units of the core are thus assembled the upper and lower ends of the core are secured in the opening in the underside of the upper header and in the opening).in the upper side of the lower header y soldering the front and rear walls of these headers to the front and rear sides of the core. The front and rear walls of the upper header extend downwardly alon the 'core at least to the first plaits of t e several units and the front and rear walls of the lower header extend upwardly at least to the lowermost laits of the units for thepurpose of rod ucing a watertight joint between the eaders and the water assages of the core. Upon assembling t e several units of the core in this manner an outwardly diverging space is formed between the outer ends of the plies of eachplait and the adjacent curved portions 14 of the webs of the plaited unit sec tion which space intervenes between the respective plait. and the convex side of the 1 locking bead 9 of the adjacent unit, thereby forming a tortuous water passage between t adjacent units which opens at its upper and lower ends mto the upper and lower water headers,as shown in Fig 2. The water radiator between the vertical flat end por g tions of thewebs of adjacent core units, as shown in Fig. 1, is filled with solder or a similar material, as shown at 17 in Figs. 3

and 5, thereby sealing the front and rear' ends of the water passages. between the several units so as to prevent leakageand also producing the appearance of comparw tivcly heavy division lines between the several core units.

A radiator constructed in the manner just described can be produced expeditiously and economically, it furnishes the maximum cooling capacity for a given amount of metal used in its construction, and the same is remarkably strong and not liable to give way and leak under the severe strains to which the same is subjected while in use.
