1'0 (ZZZ 107mm it may concern.-

Be it known that I, CHARLES W. ROGERS, a citizen of the United States, residing at Chic'ago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Radiators,'of which the following is a specification. 1

Steam and other radiators for transmitting heat and for other purposes as now constructed are of two distinct and well-known types or forms of construction, one having a body or tubular portion composed of wrought-iron pipes entered into headers either of wrought or castiron and the other having a body "or 'tubular portionand the headers made integral and of cast metal. Both constructions are expensive to make and somewhat cumbersome and heavy to handle.

The object of my invention is to construct steam and other radiators on a different plan from the practice heretofore and which shall combine cheapness and economy as regards construction with efficiency and durability in operation; and the invention consists in constructing from a single plate or from two halfplates of wrought metal a radiator as an entirety comprisingaplurality of tubes in a continuing series or set and the headers, such plate or plates being struck, stamped, pressed, or otherwise formed into shape to present a half -section of the complete radiator, each half-section having a plurality of vertical half-tubes and in a continuous set or series integral with a horizontal half-header and having also edge flanges and inner contactfaces for the two half-sections when brought together and united by welding or otherwise uniting the abutting edge flanges and the contact-faces t produce a completed radiator having a body or tubular portion and headers with the body composed of a plurality of tubes and the headers joined directly with and forming part of the tubes at the top and bottom, as hereinafter described and claimed.

In the drawings, Figure 1 is a side eleva-- tion, broken out at the center, showing my improved construction of radiator; Fig. 2, an end elevation, likewise broken out at the center; Fig. 3, a transverse section on line 3 of Fig. 1; Fig. 4', a detail in section on line 4 of Fig. 2; Fig. 5, a side elevation, broken out at the center, showing my improved construction of radiators with the tubes and headers made from a single plate by bending the plate on itself centrally to form one of the headers and showing also the induction and eduction pipes and the plugs for closing the ends of the headers opposite the induction and eduction pipes; Fig. 6, an end elevation of the construction shown in Fig. 5;. and Fig. 7, a longitudinal section through the header of Fig. 5, formedby bending the plate on itself.

In constructing my improved radiator I ing tube or thimble C for the purpose of atiaching the radiator to a steam or other supply pipe D at one header and to a dischargepipe D at the other header, as shown in Fig. 5. The opposite end of each header to that for the attachment of the pipes is to be closed by a suitable plug or cap E, as shown in Figs. 5 and 7, screw-threaded or otherwise entered into the reinforcement or thimble Gin any usual or well-known manner, orit can be permanently closed by a continuous seam. 'The body or tubular portion and the headers are struck or formed integral in sections or halves from plates of wrought metal, for which pur-' pose a plate of the requisite dimensions for the size of radiator is provided for each half or section. Each plate where two plates are employed for a radiator is struck or otherwise formed so as to have depressions, preferably semi-oval or semicircular in cross-section, which when brought together form the tubes A, as shown in- Fig. 3, and each plate has at its end or edge a flange or lip a or other suitable welding or joining face or'edge, and between each depression is a contact-face (1.. The headers are each formed at the end of the tube by a depressed portion in each plate into which the tubular or depressed portions of the body enter, so that when the two plates formed having a body or tubular portions with tubes and a header at each end of the tubes. Each header has a flange or lip b or other suitable welding or joining face or edge on its outer side in vertical alinement with.

the edge or lip a. The two plates are brought together so as to'have the edges or lips a and the edges or lips I) in engagement and also to have the contact-faces a in engagement,

and in this position the two plates are united together, preferably by electric welding, so as to form a close union between the flanges or lips a, the flanges or lips I), and the contactfaces a, making a complete whole out of the two plates or halves and a complete radiator with. a body or tubular portionand headers.

The reinforcements or thimbles C'may be in-' serted in the ends of the headers prior to welding the halves together, so as to be united to the headers in the process of welding, or they may be applied and united afterward, each reinforcement or thimble having the ends screw-threaded or of other form of construction for attachment of the pipes or the insertion of the end plugs or caps. The employment of two separate plates for constructing end and side flanges or lips, with the intermediate portion or center between the two bodies formed so that by bending the plate at the center, a header will be formed at that point, as shown in Figs. 5 and 6, the opposite header being formed by the depressed portions at the sides or edges. The radiator as a whole is completed by bringing the two halves together and joining them by uniting the flanges or lips and the contact-faces, as before described. As will be understood, then, when Ispeak of halves or sections I contemplate forming them of either a single piece of metal or separate pieces, as desired. The radiator thus formed is of great simplicity and economy as regards construction, as it can be readily and quickly formed by stamping or pressing the metal plate halves or sections so as to have edges, flanges or lips,-and intermediate contact-faces and then uniting the two halves or sections by electric welding or otherwise, so as to make a close union between the edges, flanges or lips, and the contact-faces. The welding or joining of the flanges or lips should be such as to make a steam-tight joint; but for the union between the inner or intermediate contact-faces the joint need not be steam-tight. The radiator can be made from light wrought-iron or metal plates, and when stamped into shape and the parts united will possess greater rigidity and strength than the ordinary constructions of l. Aradiator consisting of a body or tubnlar portion and headers, the body or tubular portion embracing, as a unit, a plurality of tubes, and having the entire series of bodytnbes with the headers made. from two companion plate halves or sections, each stamped or pressed into shape to form a multiplicity of straight-line body depressions, with the body depressions of one platehalf or section in alinement with and parallel with the body depressions of the companion plate half or sections, the two series of body depressions running in straight lines across the plate halves or sections and to form on two opposite sides edge depressions with the edge depressions of one plate half or section in alinement with and parallel with the edge depressions. of the companion plate half or section the two sets'of edge depressions runningin a straight line and in a right-angle relation to i the body depressions and intersecting the ends of the body depressions, each body depression constituting one-half of a straightline body-tube and each edge depression constituting one-half of the straight-line header integral with the half-tubes of the body, and to form edge flanges on the sides and ends of the plate halves or sections and interior contact-faces on the sides of the'body-tubes, for the two plate halves or sections to be joined together by uniting the flanges and contact faces, substantially as described.
