Application filed September 9, 1924. Serial No. 736,793.

The inventiony aims to provide a` radiator having considerable advantages in economy and 'efficiency and adapted to be heatedfrom various sources. The single figure 0f the drawing is a perspective view, partly in seclradiating structure of plates extending lat-erally outward. The radiating plates at one side of the chamber are preferably lmade from a' single continuous sheet bent to shape; and those on the opposite side from a similar sheet. Each sheet is thus formed into plates 4 and 5, separated at their inner edges toform triangular spaces or chimneys for the upward circulation of air. At lt-heir inner edges where theyl join the central chamber 2 there lis a short plate 6 lbearing againstand preferably welded to the chamber so as to take the heat therefrom and conduct itk outward through the parts 4 and 5.. The plates 4 and 5 of each pair comes together at their outer edges 7 where they are braced by longitudinal braces 8, preferably'in the form of angle bars embracing the corners of the radiating 'strucf ture, and thus serving also to'prevent acci ldental contact of a person with such corners. The radiatin structure thus described differs inA detail lr ber 2 is a pipe 9 for gas or similar fuel admitted throu h a cock 1 0. The pipe or burner 9 has Ori ces 11, preferably at intervals corresponding tothe points of the heating chamber which lie opposite the se arated'inner edges of the plates 4 and.

om that illustrated in my pre,l vious application 'but' is substantially the us when the gas is ignited the tiames will lie under the chamber 2 and in the lower ends of the tri-1 angular chimneys formed by the plates4 and 5 and the sides of the chamber. For use with gas it is desirable that hot water be supplied to the chamber. The pipe lfat the bottom and the pipe 12 'at the top may be used for introducing and withdrawing such water or for permitting the escape of steam.

A third heating means is illustratedfconsisting of coils 13 of resistant wire suitably insulated and mounted in the outside spaces between the plates 4 and 5. A. cable 14 is illustrated for attachment to a socket to connect Vthe electric heaters to the circuit.

I prefer to use for the heating chamber. and for the radiating structure a metal of great heat conductivity, such as copper, brass or zinc, which are much superior to the ordinary metals, iron and steel. By using copper or brass in thin sheets I get a sufficient increase in eiiiciency to compensate for the increased cost per pound. ,p For example, I may use plates ot' about one-sixty-fourth of an inch in thickness extending outward from one to 'six inches. The chamber ,2`should be narrow, as indicated. Radiators of thisA design and oi these materials and dimensions are particularly advantageous because they can be easily equipped with 'gas boilers and electric heaters in the manner indicated, and these heaters can be located so as to secure the best application of the heat to wat'er carried in the chamber 2, the chamber being equally adapted for steam or hot water circulation. l

The electric heaters stitfen the entire strucf ture against distortion, which is important with such thin sheet metal. Itjwill be observed that the gas flames and the velectric heaters are applied at alternate points along the side of' the chamber. come up through the chimneys formed'b the sides of the chambenwhile the electric heaters are inthe angular spaces which are open to the outside. It is contemplated that the. radiator shall be. equipped with boththese The gas flames `heating instrumentalities, as well as with couplings to which pipes may be attache@ for steam or hot water circulation. If any one of these methods does not give the required y amount of heat. two, or eventhree, of them can be used at the' same time, there being no interference between them.

An important feature of the invention is in the vertical extension of the transverse -plates formed by the corrugated structure.

. columns of air which are progressively heated on both sides by prolonged contact with the heated wallsof theducts and are thus impelled rapidlyupward so as t0 accelerate the circulation olf the heated air columns upward from the! ducts and throughout th room or inclosure to be heated. v L

The ducts between transverse plates which converge at their outer edges are in fact fiues closed in cross-section and adapted to produce an even greater draft upward than the spaces between such fiues; the draft being slower in the latter because of the admission of cool air at the open outer side of the duct.

The actiontakes place either with or without 'water-fin the water chamber 2, the edect of water'V therein being merely to maintain. a

store of heat for a certain length ofjtime' afterjhel electric current is cut off.

The ducts act in the'same way when the heat is supplied from the fuel pipe or burner 9. This burner in fact constitutes a heatingl element located solely at `the bottom 'of the ducts described; in contrast with the electric heating devices which are .attached to the transverse plates not only at. the lower or- A tions of the latter, but throughout t er height.' v i The result of, this structure of vertical ducts is that instead of a relatively stationary or slowly rising and laterally diffusing -overheated body of air around a heating element and underheated air in the remainder of the room or inclosure, there is obtained a greatly accelerated vascent of warm columns of air through the heated duets and upward therev from and thus v'a forced circulation and distribution of evenly heated, air throughout the entire inclosure. y l Specific claims for the electricheater are not presented in the present application, being covered in a co-pending divlsional application No. 331,347, filed January 9, 1929.

Though I[ have described with great particularity-of detail certainembodiments ofI .myinventiom yet it is not to be understood therefrom that'the invention is restricted to thevparticular embodiment disclosed. Various modifications may be made by those skilled in the art without departing from the invention as defined in the following claims.

What I claimy is: i

1. A combination heater. and radiator including in combinationa chamber for a fluid heating medium, a radiating structure comprising vertically extending plates mounted on the 'outer faces of said chamber and forming flues which are closed in cross section along the-sides of the chamber, electric heaters in contact with the outside of the chamber between said fiues and a gas burner below said chamber with orifices registering with said fiues and alternating with said electric Y heaters along the length of the chamber.

2. A combination heater and radiator including incombinati'on a chamber for a fluid heating medium having fiat vertical sides, Ka radiating structure ofplates engaging the sides of the chamber, extending laterally outvward and forming with the chamber wall vertical flues which are closed in cross-section and spaced apart from one another, electric kheaters located in the spaces .between the fiues and adjacent tothe chamber, and a gasv burner below the chambervwith orifices registering with said flues and alternatingwith said electric heaters along the length of thev chamber, so that the fiames passup the'ues between the electric heaters and are separated from 'said heaters by -the'plates 3. A combination heater and radiator including'in combination a chamber for a fluid heating medium, a radiating structure comprising vertically extending plates mounted on the outer faces ofsaid'chamber and forming verticalfiues alongthe sides of the cham- \ber and a burner below lthe chamber with orifices registering with said flues.

4. A combination heater and radiator comprising a burner, a fluid chamber and a longitudinal series of transverse-plates fixed in relation to said burner and chamber, said plates being substantially free'of intervening' obstructions and rising vertically from the burner to a height relatively great compared to their width, and forming a longitudinal series of unirnpeded heated vvertical air ducts.

In witness whereof,-I have hereunto signed my name.
