Patented Apr. 9, 1935 UNITED STATE FIN RADIATOR Austin H. Hart, Long Branch, N. .L, assignor, by V mesne assignments, to Heating Appliances and Equipment Company, Incorporated, a corporation of Delaware the'radiator body, by placing same over the top "thereof.
Another object is toconstruct the fin member in such manner that each fin is'a'dapted to tightly grip the radiator body, thereby forming a good metallic contact therewith'and. retaining a j grip which cannot be readily loosened unless force is applied. V
Among other features are improved means to properly space ,saidifins and means to assure a good surface contact between the fins and radiator body if thebody is cast and has a wavy surface.
By my arrangement the fins areformed from one metallic sheet which has equally spaced openings punched through from one edge, and flanges forming the sides of each opening. After the punching operation the fins are alternately folded, thus forming a sinuous-fin structure with a channel at one edge, formed'by the aligned punched openings.
After the fins are formed they are easily assembled as a unit by placing said unit over the radiator body and forcing same downward to the limit of the openings. Due to slight irregularities in alignment of the slotted openings an excellent clamping engagement is provided between the flanges of said openings and the radiator body;
The preferred form of structure is shown in the accompanying drawings, in which Fig. 1 is a perspective view of a complete radiator assembly with parts broken away to clearly show the body construction.
Fig. 2 is a side elevation of the structure shown in Fig. 1 with a portion broken away.

Referring to the drawings in which like refer-. ence'characters indicate' likeparts, the reference character It refers generally to the radiator body and12 to the fin structure.
The said body 10 preferably comprises a one piece cast member consisting .of a hollow core l4 having a chamber l5, end portionsl6|8 formed integrally, therewith, and bosses-20-22 at the lower corners. It will be observedthat this onepiece cast body provides a very rigid structure which requires only the boring and threading of two holes 2628 for inlet and outlet. connections,
assemble endfittin'gs on the core, which is the usual practice in the construction and assembly of fin radiators. Feet: 3!!32 are formed as a 'thuseliminating the time and.1abor required tov part'of the bosses 20-22, which are flat at the bottom for the purpose of supporting the body in an erect position when placed on .the floor, and they project below the lower surface of the. core to protect said core from sudden shocks when it is moved about, also to provide suflicient metal so' that the threaded openings :26428- may be low enough to permit proper drainage. The walls of the ends l6 and'l8 are made somewhat thicker than the core walls to provide shoulders or abutments'34--36.1 An air valve (not shown) is to be placed in either one of the positions indicated at 38-40, according to the heating system used. The fin member l2 comprises a conntinuously folded metallic sheet,-fo1ded in alternate or zig .zagorder, providing a multiplicity of substantially parallel fins 42. Before folding. the sheet is run through a press or other forming machine, which punches openings 44 and forms flanges 4$48 at the edges of each opening in alternate directions as indicated in Fig. 5. The openings 44 go through the lower edge of the sheet and r 64'66 from one end of each of said sections; and
adaptedto engage'a core Gil-from above and below,
tight grip, a good metallic contact is made which is suflicient to assure adequate heat conduction :without resorting to dipping in a galvanizing bath. The latter may be resortedito however if desired;
Several staggered projections: 50" are formed" on each flange 46-48 which engage the wall of the adjacent fin, thereby definitely spacing the fins and preventing the flange of bneflnfrom slipping P. ,under the flange of an adjacent fin; Inwill be.ob-.
