RADIATOR 7 Filed June 18, 1928 Patented Apr. 26, 1932 NITED STATES nmvruivn I. .MAZURETTE,

OF DENVER, COLORADO RADIATOR .Application filed June 18,

My invention relates to radiators of the type used in heating systems, which byconduction, convection and radiation transmit the heat of steam, hot water or other heating fluid, passing through the system, to a room or space in which the radiator is disposed.

It is an object of the present invention to provide in aradiator of the above stated type certain features which combine lightness,

compactness and economy in construction with superior efficiency and practicability in use.

Principal among these features is a means whereby the duration of contact ofthe air 13 with the heated surface of the radiator and the direction in which the air travels along the surface are predetermined-and controlled so as to increase the volume of air which can pass over the radiator, minimize'waste of heat, prevent damage to walls, draperies and other objects immediately behind the radiator, and provide for the rapid transmission of the heat to the air within the room, 7

Another distinctive feature of the invention resides in passing the heating medium through the radiator in small volumes anda thin stream, in which form it gives up its heat most readily by rapid cooling and condensing. v r

The above "and other objects all" of which will be fully brought out in the course of the following description, I attain by the'novel features of construction included in the embodiment of the invention accompanying drawings.

Figure l' of the drawings represents an end-elevation of two units of a radiator made in accordance withmy invention, v

Figure 2, a side elevation of the units shown in Figure a r Figure 3, a top or plan view of the same, Figure ft, a fragmentary section taken on the line 4 4i, Figure 2, and I p Figure 5,-a fragmentary elevation of three units assembled into a radiator.

Like reference numerals designate corre sponding'parts throughout the views. Referring further to the drawings, each unit of the radiator consists of a single flue 1 of oblong horizontal section, arched at its 1923. Serial no. 286,435.

top and bottom and provided with suitably formed legs it when desired for its support on the floor of a compartment in which the radiator is installed. 2 The side-walls of the unit have adjacent the top and bottom. of. the flue, outwardly projecting hollow bosses which provide portsv 3 for the ingress and egress of the heating fluid, and egress of condensation, andwhere the radiator is composed of a plurality of units as illustrated in thedrawings, connect- 7 ing bosses 2 at the opposed sides of the units are placed in register with each other for the passage of theheating fluid and condensation from one unit toanother in a circulatory movement l The units are furthermore provided with air-relief P0113845 v The flue provided by each unit is interiorly of short length in comparison with its width and height so thatthe heating medium pass ing through the flue is spread in the form of a thin stream or sheet to secure rapidtransmission of its heat to the walls of the unit;

a The inner surfaces .6 of the walls of each unit are plainand smooth to offer the least resistance to the flowof the heating medium and condensate and to simplify construction.

The outer surfaces of both side-walls of the inner units A of a radiator and the outer surface of one ofthe side walls of the outer units B of the same, are provided with a :plurality of parallel ribs 7 inclined at an illustrated in the angle upward from the back and bottom of the units and spaced apart to form a series of correspondingly extending channels 8 of considerable depth, and the'end-walls ofthe units mayhave vertical ribs 9 which likewise provide channels 10 into which the air inside the room may-enter. 1 In the use of the radiator composed of units of the above described form andconstruction, the heating fluid passing through the flue in the form of a thin stream. or sheet rapidly transmits its heat through the walls of the unit by conductionwhence the heatis transmitted to the air within the room and to adjacent objects by convection and radiation. Owingto the smooth surfaces atthe inside of 'theflue, the heating medium flows in an.

unobstructed stream and without other than frictional resistance between the ingress ports and egress ports, and thereby transmits its heat to the walls of the unit at its maximum temperature in a substantially continu ous operation.

Owing to the presence of the ribs and channels, the outer surfaces of the units are of considerably greater superficial extent or area than the inner surfaces of the same and thereby efiect a closer equalization of the rates of heat transmission by conduction and convection and a large increase in effective heating surface and corresponding rating.

It is to be observed that this increased heating surfaceis obtained without increase in the bulk, weight or cost-of production of theradiator and. that infarct, in proportion to the rating, these three essential factors are considerably decreased.

' The'channels slanting upwardly from the 7 back and bottom of the units as hereinbefore described, have, however, other functions that are of vital importance in the operation of the radiator insomuch as they greatly enhencev the, efficiency andpracticability of the same.

The value of the channels will be readily apparent from the. fact. that they increase the volume of. air contacting with the heating surfaces of the radiator, that they provide-for the continuous movement of this volume of air, and that by controlling the direction of travel of the air, they provide a greatly enlarged air orifice which makes possible acorrespondingly increased volume of air that can travel'over the heating-sur faces, with greater average temperature'differences between the air and the heating medium, the air volume being in fixed ratio with the heating surface regardless of the height ofthe radiator, and eliminating dead heating surface.

The. direction of the channels moreover, causes. the air currents terfiow away from the wall behind the radiator, thus protectingthe wall, draperies or other adjacent objects; from the damaging effects (if a vertically ascendmg or uncontrolled column of highly heated air produced in the operation of radiators of types heretofore used, thus. acting as a shield andpreventin rapid and wasteful flow of heat through t e wall dueto increased temperature difference between its inside and outside surfaces. The simple flue construction of the units,

combines simplicitywith increased efficiency owing ta the small volume of the heating medium passing through the flue, proportion to the area of wall surface which it serves, and the channeled construction, of

' the units, as; shown described, is highly advantageous for the reasons liereinbeforeset. forth, e

. The positive controt of the directionv of tion,

the air travel over the heated surfaces and the absence of obstructions to said travel, limit the duration of air-contact with the heating surfaces and thereby render every part of the surfaces active at all times. It

the channels inclined at an angle are also valuable from an economic point of view by preventing damage to the walls, draperies and other adjacent objects and by preventing waste of heat through the walls-as stated hereinbefore.

In constructing a. radiator of units made in accordance with my invention as hereinbefore described, it is desirable that the. outer surfaces of theouter units be smooth and without channels, as. illustrated in Figure 5,

to permit: of ornamentation of the exposed surfaces, and to eliminate unsightly .ribs where they are, of least advantage.

' It will be apparent that the slanting channels are most effectivebetween the unitsf more particularly since in ordinary radiator construction the intermediate units are not as: fully exposed to the atmosphere as are the outer units and do not permit of the. passage of sufficient air along their heating-surfaces 0 give full thermal value of the radiated eatr The ribs may be extended so that those of the adjoining units can meet to conjointly form slanting channels for the circulation of the air as: has been shown at 12 in Figure 5 and in this modifiedfccnstruction it is: ad-

' vantageous; that part of the ribs be of smaller height as shown at 13, to give sufficient: space for the P P Q Of cleaning the channels of" the. radiator between the units: thereof, whenever necessary.

What I claim and desire to secure by Lette'ISi Patent is:

1. A multi-section radiator comprising assembled units,.-opp.osed side walls of which have a multiplicity of parallel ribs. slanting from adjacent. the bottom and rear edges; of the; walls, to adjacent te tap and front edges M of thesame, some of the ribs of the units adjoining oneanother to cooperatively form channels; for the. slantingly" upward passage of air between the units, and ribs between the adjoining ribs; being of lesser width to provide with-in the channels, separated grooves. assisting in the: passage; and heating 7 of air, and permitting the insertion of a brush toclean a multiplicity of ribs at one opera- 1 2;. A multi-section radiator comprising as-' no sembled heating-units each composed of a hollow vessel the side walls of which are adapted for the transference of heat to outside air, said walls having exterior parallel ribs forming grooves slanting in straight lines from points along the bottom edges and rear upright edges of the walls to points along the top edges and front upright edges of the same, and the units being assembled side by side with the grooves in opposed sides registering with each other to jointly provide a series of straightway channels between the units for the slantingly upward passage of air in the direction determined by the relation of the points between which the grooves extend, and with the ribs spaced from each other for the insertion of a brush to clean a multiplicity of ribs at one operation. 7

In testimony, whereof I have aflixed my signature. 7
