To all whom it may con-cem.'

Be it known that I, IRWIN J. FRENCH, a citizen of the United States, Pittsburgh, in the countyof Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

This invention has reference to improvenientsin radiators adapted for use in connection with steam, hot water or vapor lieating systems and primarily my invention seeks to provide an improved construction of radiator, of the general character stated, that is especially designed to dispense with the use of legs orbrackets for supporting the radiator projected out 'from the wall surface and adapted for being operatively positioned against the wall surface so as to make an even finish with the front wall fa'ce, flush with the plaster. j Another object of my invention is vto vprovide an improved construction of radiator, which improvement may comprise but'a single unit for connection with the heating element flow pipe and the return vor a plu'ralityof units capable of being assembled in endwise relation'and adapted for connection with' one' inlet and one return 'and which have provision for beingreadily held in cooperative connection, by animf proved clamping means to avoid the necesl.

Vbody type and is designed for being yposisityof; assembling the several sections by bolts orf right and left nipples, as is usual when joining up the conventional types'of radiator sections. i Again, my invention seeksto provide an improved radiator whose body is shapedfor being supported 'against the wall with its front or outer face flush with the wall face,

that can be'conveniently and? easily manufactured and which effectively serves its intended purposes. 4 (With other objects in view that will hereinafter appear, my invention embodies, in a radiator, the' peculiar features of construction and novel arrangement of parts, all of which will be brought out in the following detailed description, specifically stated in the appendedlaims and illustrated in the accompanying drawings, in which Figure ll is a front elevation of my 11nprovedradiator, the same being yshown as composed of two individualsections joined end to end and connected with a single inlet residing at the reason for which will presently appear,

` and vreturn, system, the same bein shown as operatively positioned on the wal Figure 2' is a detail longitudinal, section which illustrates one of the clamping vdevicesvfor holding the two adjacent ends of a pair of radiator sections in {luid-tight.l

connection, one of the tubular push pin devices being also shown in this view.

vFigure 3 is a detail rear elevation of a portion of the adjacent endscf a pair of radiator units and showssome ofthe heat radiating pins hereinafter mentioned.`

Figure 4 is a transverse section of the ,radiator taken practically on the linee-4 of Figure V1 and looking in the direction of the arrow.

Y Figure 5v yis a perspective View of a single unit radiator having an inlet and a return connection, parts being broken away and in sectionto the better illustrate/the internal construction."

Figure 6 is a lvertical section ofthe inlet or inflow end ofthe radiator section shown in Figure 5. l 5 f l' Figure 7 is atop plan view ofthe adjacent ends of ai pair of radiator units and the clamping'devices for holding the said units or sections in fluid tight relation.

In the practical development of my improved radiator and when the same'comprises but 'a single unitfasv is best shown in Figure 5,l the said radiator 'is ofthe at tioned resting upon the room Hoor and to formed in the wall and extending up from the floor, as indicated in Figure 4f, by lrefer- 'ence to whichit will be noticed the radiator body lhas a perforated flange 2 that projects alongthe top and the opposite ends of the body andwhich constitutes a closurefor the spacea in which thev radiatorunit is set, the lsaid b ody, in practice, being set a slight distance awayy from the back andthe opposite end faces of the space or recess a,

and to increase; theradiating surfac the body 1 the back lwall is castwith tapered cup' shaped pins or lugs" 3, Figures, 4 and 7.

nProviding the radiator vbody with a surrounding' ,perforated ange alon the upper 'and the opposite A.front ed es t ereof and a circulating space/for the heat generated by the back, topand end walls of the radiator, is provided, and since the flanges 2 are perforated along their ,entire length, as in dicated at 4, provision is made for the ready escape of the heat that circulates in the pocket or space a into the room.

By mounting the radiator body solidly upon the floor and with its front face flush with lthe wall surface no part of the radiator is projected in the room and the need of lugs or hanger brackets for Supporting the radiator projected within the room is y avoided and the need of` floor space, and the the upper end, as is clearly shown in Figures 5 andV 6, by reference to which it will be noticed the end wall 20 of the vradiator proper has a number of inlets 5, (four being shown) which` align with relatively shorter apertures 12 in the tubular portion 9, the said apertures 12 being provided to permit of drilling the smaller apertures 5, it being understood the .several apertures 12 when building up the radiator sections provide entrance to loosen up the sand core and after the holes 5-5 have been drilled, as stated, 'the saidk openings `12 are closed by suitable plugs 12a, as shown. l

The lower or inlet end of the tubular portion 9 of the radiator body 1 terminates in a pendentthreaded inlet 90 for conveniently connecting the said end 90 with the control valve 10 in the inflow or feed pipe 10% In practice, av maximum efficiencyV4 of the radiator 1 is acquired by making the several inflow apertures 5 through Vthe body end 20 of such size that the combined area of all of the apertures 5 `equals the area of the single inlet 90.

In my improved construction ofhradiator body the same is cast with a series of horizontally disposed longitudinal division walls or bales 6, 7, 8 of progressively increasing length, the upper or longer one being sufli ciently shorter than the internal length of the radiator body to thereby provide" for the free circulation of the heati'ng'element that may be fed into the radiator body in the manner presently explained and since the division or bale members are cast with the front and back walls of theradiator body, the said members 6, 7, Siactas reinforcing elements for preventing buckling of the said front and back walls of the body.

`When forming the radiator body 4or unit 1 shown in Figure 5, the bottom and outer ends of the said body are cast with openings 14-15 and the several openings 14 and 15 provide. for'taking out the casting sand. lVhen the radiator body is finished, all of the several openings 15 and 14 excepting the outermost bottom opening 14 are plugged, the outermost opening 14 being utilized as a return outlet for connecting with the return pipe y.

lVhen my improved radiator structure is formed of a plurality of units, two, for example, as shown in Figures 1, 2, 3 and 7, the several units are constructed asshown in Figure 5 except that the tubular end inflow sections 9 are dispensed with and each of the radiator sections is provided with an aperture 13 (see Figure l). When formed of two sections, as in Figure 1, the two units are placed end to end, the aperture 13 in the one section constituting an inlet for being Valve coupled with the inflow pipe, and the like aperture 13 in the other section constituting the outflow for being valve coupled with the return pipe, as shown, it being also shown that the' two apertures 15-15 in the abutting ends of the two sections 1-1 are left open and all the apertures 14 other than the end ones referred to are plugged.

To provide a convenient, simple and easily applied means for holding the two radiator sections in fluid-tight relation and to act,

as it were, as a single heat radiating body, as arranged in Figure 1, the abutting or adjacent ends of the two units are each formed with transverse dove-tailed lugs 16-16 that extend crosswise of the top and bottom faces thereofand each of which is made tapering in plan view, (see Figure 7).

17-17 designate tapering and wedge shaped steel clamps that are adapted for engaging the opposing pairs of dove-tailed llugs 16--16 and which are adapted for being hammer-driven home, it being understood that as the' steel clamps 17 are driven. home, the adjacent ends of the two sections 1-1 will be drawn up against one another, fluid tight and when vthus assembled the clamps 17e-17 vare held to their clamping adjustments by set screws 18--18, asshown.

As before noted, when two sections 1-1 are joined, as in Figure 1, the apertures 15-15 inftheir return end are left open, and to provide for a tight closure at the communicating apertures for the two sections, tubular tapered push pins 19--19v are provided, and as the yholes 15 are tapered it follows that as the two abutting ends of the units 1-1 are drawn together by the clamps 17-17 the push pins which forni the means `for communication between the two sections 1--1 are held in tight relation with respect to the abutting ends ofthe radiator body, see lFigure 2c By reason of connectmg the twosections mamie 1-l. as slated and shown. the use of bolts or right or left nipples is dispensed with.

The return radiator section` when the radiator is formed as in Figure 1,1nay be equipped with the usual valve air vent 2l.
