parallel relation with common inlet and outlet passages for said sides.

It is still another object of the invention to provide a radiator comprising a vertically disposed narrow chamber formed by spaced plates folded into zigzag substantially V- shape folds, said radiator having outer sides diverging at one end and then extended substantially parallelinsaid zigzag folds, said radiator having inner sides which extend reversely to the outer sides and substantially parallel therewith, said inner sides being connected at their ends and having a common outlet. I I

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the-accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which,

Fig. 1 is a view partly in plan with certain portions broken away, and partly in horizontal section;

Fig. 2 is a view in side elevation of the radiator with the central portion broken away;

Fig. 3 is a vertical section on the line 33 of Fig. 1, as indicated by the arrows and shown on an enlarged scale; and 1 Fig. 4 is a view similar to Fig. 1 showing a modified form of the radiator.

I Referring to the drawings, particularly Figs. 1, 2 and3, a radiator is shown comprising vertically disposed narrow water chambers 5 formed by spaced vertically disposed plates 6, extending toward each other in a nected by a suitable posed at each side of and adjacent Serial No. 504,185.

somewhat inclined direction from the topand bottom and being connected together. While various forms of connecting means may be used, in the embodiment of the invention illustrated, theplates are shown as welded together (see Fig. 3). Chamber 5 comprises portions 5a which are in communication at one end of the radiator and have connected thereto theinlet conduit 7 said conduit being shown as connected by a suitable nipple Sand elbows 9 to a steam or hot water supply pipe 10. The portions 50, diverge at a comparatively wide angle and are then bent into zigzag folds 56 substantially V-sha'ped in form. The zigzag folds 51) extend longitudinally at each side of the radiator andin substantially parallel relation. the other end of the radiator, the chambers 5 extend .reversely to form the zigzag folds 50, also substantially V -shaped in form, which extend .in a direction substantially parallel to that of the folds 5b and within the latter. The

inner ends offolds 50 are connected at 561 a and an outlet pipe 11 connects with this common point of the folds 50, said pipe being connipple 12 and elbows 13 1 1. Brackets 15' are dis- 7 each end of the radiator adapted, to rest on the floor or other, supporting surface and said brackets have substantially V-shaped portions 15a extending upward a short distance into the to a discharge pipe .angle between

portions

5a and 5b. The

brackets 15 are connected by rods 16 extending therebetween and threaded thereinto at their ends, said rods being equipped with suitable jamb nuts 17. At the end of the radiator opposite the pipes 7 and 11, the rod 16 passes through triangular blocks 18 extending upward into the angle between folds 50, said blocks also being contacted by the jamb nuts site pipes 7 and 11 is also provided with suitable air relief cocks 20. It will be noted that the inlet 7 is substantially at the upper end of chambers 5 while the outlet pipe 11 is substantially at the bottom of the radiator. A cover 21 is provided composed of thin flat metal having a diamond-shaped latticework" formation and having a flange 21a substan- 19. The radiator at the end oppotially rectangular in form adapted to fit around the outside of the radiator and ex tended downward a short distance from the top thereof. The width of the various strips 21b of the cover are illustrated as somewhat wider than the chambers 56 and 56.

In operation, the heating fluid will enter the radiator from the pipe through the pipe 7 and will pass through both of the memcrs 5a through the folds 5]) and reversely through the folds 50, passing out through pipes 11 and 14. The outer sides of the radiator formed by the chambers in folds 5?) will be the hottest part and these sides are exposed to the atmosphere of the room to be heated. The cooler part of the radiator will be that formed by the folds 5c and the exposure of this part of the radiator is not so ellicient or so important as that of the outer side. By having the adjacent points of

folds

5b and 5c alined, a series of passages sub stantially diamond-shaped in cross section are formed, which, together with the space between the members 5a and the inner ends of folds 5c, are enclosed by the radiator or the chamber 5. The air can thus pass" upwardly through the radiator and a large proportion of heating surface is obtained relative to the amount of heating fluid used. A very efiicient radiation is thus obtained. The radiator is particularly adapted to ltc made from sheet metal. The plates for the various portions, such as the outer folds an and the end of members 5a and the inner sides ormed by folds 50, can be made separately. The plates at each side of the chamber 5 can then be connected at top and bottom, as by welding, and the various sections then connected at their meeting ends and" welded, A substantially unitary structure is thus obtained. The folded form of the radiator gives ample opportunity for expansion and contraction. The structure is thus extremely simple and very efficient.

In Fig. 4, a somewhat similar radiator is shown having only the two sides. The radiator also comprises the narrow chamber formed by the spaced plates 26 which are arranged in substantially parallel members or sides, each formed in a series of folds 26?) substantially Vshaped in form. The folds 26b, at each side of the radiator, are arranged with their adjacent points in trans verse alinement and the two sides are connected at each end of the radiator, an inlet pipe 27 being provided adjacent the top of the radiator at one end and an outlet pipe 28 being provided adjacent the bottom of the radiator at the other end. The' plates 26 will be connected at their tops and bottom in some suitable manner, as by welding. A top 29 is also provided adapted to correspond to the ends of the radiator and having the parallel side portions 29a provided with a vertical flange extending downwardly a short distance and comprising the intersect ing or latticework arms 29?) which are somewhat wider than the chambers 25.

In operation, the heating fluid will enter the inlet pipe 27 and will pass in both directions to the opposite sides of the radiator to the other end thereof and pass out through the outlet pipe 28'. A very efficient radiating eliect is obtained as there is a large exposed surface in proportion to the volume of heating fluid. The two sides of the radiator form-an enclosed space composed of substantially closed passages diamond-shaped incross section, through which the air can pass upward. The radiator shown in Fig. 4, like that shown in Fig. l, is especially clesigned to'be made of plate or sheet material and can thus be easily and inexpensively produced.

It will, of course, be understood, that vari ous changes may be made in the form, details, arrangement and proportionsof the parts without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, in the novel parts and combinations of parts, disclosed and defined in the appended claims.

Cross reference is hereby made to my previous application for United States patent on this same invention, filed January 30, 192?)", Serial Number 84,961, and entitled Radiator for heating, formally allowed August 9, 1928, forfeited for failure to pay the final Government feethereon and not renewed.

l Vhat is claimed is=- 1. A radiator comprising narrow vertical chambers diverging from a common end portion and then formed into substantially V- s'haped zigzag folds and extending in spaced parallel relation to form the outer sides of said radiator, said sections then extending toward each other and reversely in V-shaped zigzag folds substantially parallel to each other and parallel tofsaid first mentioned folds to form inner sides of said radiator, said inner sides being joined at their ends, an inlet conduit at said first mentioned common end portion and an outlet conduit at said last mentioned end portion.

2. The structure set forth in claim 1', said chambers having their portions diverging and spaced from said common end parallel to the end portions of said inner sides which are joined together. v

3. The structure set forth in claim 1 the points of the V-shaped folds of said chamber at the outer sides of said radiator having their inner points adjacent and transversely alined with the adjacent points of said V- shaped folds of said inner sides.

4. A radiator comprising, narrow vertical chambers joined at one end, an inlet conduit at said end, said chambers diverging from said end, then extending generally parallel to each other, then extending toward each other and then extending in general parallel spaced relationship between the first parallel portions in a direction towards said first end, and then extending toward each other to join each other and an outlet conduit leading from said chambers.

In testimony whereof I afilx my signature.
