RADIATOR Filed oct. 2e. 1931 2 sheets-sheet 2 Patented May 30, 1933 UNITED STATES PATENT OFFICE ARTHUR B. HODIN, OE RACINE, WISCONSIN, ASSIGNOR TQ MODINE MANFACTURING A COMPANY, F RACINE, WISCONSIN', A CORPORATION 0F WISCONSIN RADIATOR Application led October 26, 1931.

The invention relates to improvements in radiators and has among its principal ob]ects the provision of a radiator comprised of a member having a plurality of fluid passages I formed integral therewith to provide means fory heating by radiation and to assoclate a heater element with said member, the latter being in communication with the fluid p assages of said member to thereby provide means of the latter for heating by convectlon.

-It is also an object of the invention to provide a heater comprised of means for heating by radiation and convection, said means being connected in series with each other so that the heating fluid is compelled to circulate from one to the other prior tol its discharge therefrom to the return pipe of a heating system. i

It is a :further object of the invention to a0 produce a structure having the ,above mentioned characteristics which is capable of being associated with a casing or a recess pro vided in a wall of a building to thereby provide one wall of the recess or casing, the member having the means for heating by radiation and convection being arranged rel atively to the casing so that'airl passages are provided at the opposite ends of said member to thereby provide for circulation of air into ao and out of the recess or casing.

It is an object of the invention to construct the member having said plurality of iiuid passages with means for controlling the dow of heating medium through said passages and to arrange a means for manipulating 'said controlling means so that said manipulating means is accessible from the outside of the casing or recess, one wall of which is formed by said device.

The invention has these and other objects, all of which will be explained and more readily understood when read in conjunction with the accompanying drawings which illustrate one embodiment of which the invention is susceptible, it being manifest that changes and modifications may be resorted to without departing from the spirit of the appended claims forming a part hereof.

constructed in accordance with the invention Fig. 2 is a section taken on line 2-2 oi Fig. 1; i

Fig. 3 is a'section taken on line 3--3 of Fig. 2,; 4

Fig. 4 isa section taken on line 4 4 of Fig. 3; and

ig. 5 is a section taken on line 5-5 of Fig. 3.'

The structure disclosed in the drawings for accomplishing certain of the various objects of the invention such as heating by radiation contemplates the utilization of a plate-like member 10 having fluid passages 11 and 12 and transverse passages such as 13-13 connecting the passages 11 and 12 which are formed integral with the plate-like member 10. The fluid passage 11 communicates with the passage 12 through the medium of the transverse passages 13 and since the plate with these passages formed therein is a single casting, this arrangement provides a means for heating byradiation, it being understood that the passage 11 has an opening such as 141 provided therein which is adapted to be connected with a fluid supply pipe 15 of a heating system.

It may be here stated that in the present disclosure the passage 11 is provided with a tubular extension 16 which is threaded as at 17 for effecting a connection between the passages such as 11, 12 and 13 and the Huid supply pipe to thus supply fluid to said passages and another element connected with these passages which provides means for heating by convection and is generally designated 18. The tubular extension 16 also provides the body 19 of avalve generally designated 2() and thus will reduce the number of 1gb fittings necessary to be employed to connect the device with the heating system. The stem 21 of the valve is arranged so that it is accessible for manipulation from the outside of the casing to control thedow of heating fluid through `the device when said plate-like member 10 and its associated elements are arranged to provide a wall of a recess or casing as hereinbefore referred to.

The passage 12 of the plate 10 is provided x 100 I 35 referred to and having the heater element 18 ing 24 is adapted to be connected with the rethe opening 35 which may be turn pipe of a heating system. The casting 24 has a wall 26 which divides the casting into separate sections or chambers to thereby compel fluid circulating from the passages 11, 12 and 13 to the casting 24 to circulate from one of the chambers such as 27 formed by the wall through the U-shaped tubular branches 28 and 29 and thence to a chamber 30 from which it is discharged from the casting to the return pipe of the heating system. The U-shaped branches 28 and 29 of the heater generally designated 18 are provided with a plurality of heat radiating iins such as 31, the fins being disposed relatively to each other to provide spaces such as 32, the latter of which provide air passages and allow air to circulate between said tins and topengage with the U-shaped tubes such as 28 and 29 to thus heat by convection.

It will be noted that the structure thus far explained which involves the use of a plate such as 10 having the passages hereinbefore connected therewith provides a structure which will permit expansion and contraction of the plate-like member 10 without transmitting these strains to the tubes of the heater element 18 which will thus eliminate the possibility of cracking or breaking of joints and.

consequent leakage between the p'arts of the structure.

From an inspection of Fig. 2, it will be evident that the member 10 which provides the element for heating by radiation will, when associated with a recess provided in a wall of a building or with a casing such as that generally designated 33 provides one wall of the casing with. a heating device such as 18 extending into the casing which will arrange the element 18 in the path of travel of air entering the recess to thus heat by convection.

"'1'0 provide for circulation of air through the casing the lower edge of the plate such as 10 is spaced a suitable distance from one end of the casing which provides an opening 34 to allow air to enter the casing, engage the tubes such as 28 and 29 of the hea-ter generally designated 18 and also the fins thereof, heat said air and cause it to travel in an upward direction and out of the casing througn produced by arranging one edge of the plate 10 in spaced relation to one end of the casing or recess.

It may be here stated that the valve for controlling the iiow of the heating mediumthrough the device may be of any desired character, that is to say, it may be of the type shown or be of the packless variety such as now found on the market.

From the foregoing description of the dey vice, it is evident that a simple arrangement. 1s provided whlch produces a unitary structure having means for heating by radiation and means for heating by convection, the former comprising a plate having a plurality of tubular passages formed integral therewith and the latter being formed by a device including fluid passages having ins and spaces provided between the ns to allow air to pass therebetween and be heated to thus heat air by convection, the structure allowing for the expansion and contraction 'of the elements without fear of breakage or leakage of the parts entering into this construction. It is further evident from the foregoing that by providing the element 10 with a valveoperable from the outside of the casing that this lends to simplicity of the device and facilitates installation. l
