SHEET-METAL RADIATOR.
Application filed December 31, 1925. Serial No. 78,546.
f Our invention relates to radiators and is concerned chiefly with the construction and assembly of pressed metal radiators. j
Radiators of thin pressed metal, copper for example, Will require less time to heat up andwill more readily give up their heat than the heavier cast metal radiators. This renders them especially desirable kas portable radiators, where quick heating is an essenl0 tial.` Moreover, they may be made in pleasing designs and at less cost than cast radiators, and can be plated readily or painted to harmonize with their surroundings. The chief drawback to their general use has been the dili'iculty of so assembling these radiatorsthat they can be readily disassembled for the replacement of a damaged or leaking unit, the construction heretofore used, so far as we are aware, making is necessary to permanently connect all units of such a ra diator so that when a single leak developed it became necessary to discardthe entire radiator. Further, the complete assembling of the ent-ire radiator during the course of `its manufacture at the factory heightened the initial cost of the radiator and shipping costs.
Important objects of our invention are, therefore, tov provide a radiator which can be made of thin sheet meta-l, `and of soft jmctal, ascopper, if this bc desirable; which canbe assembled from the pressed plates without an expensive investment in machinery and, therefore, which can be pressed into shape at the factory, shipped knocked down, and assembled` at the destination, or which can be assembled into single units which can be more conveniently shipped than a complete radiator, and 'from which radiators ot' 40 as many units as are desired can be assembled without the necessity of special tools; and to provide a radiator of pressed metal which can be disassembled and repaired and again assembled,or in which a damaged or 'leaky unit can be replaced without the use of special tools. j A further object Vis the provision in a radiator, particularly one of this type, ot' a construction providing` a cheap and conven 5o ient mounting for` a heating element.
j A further object is the general cheapening of the cost and the improving of the assemd blyof such radiators.
Qur invention comprises the novel parte and combinations thereof, as shown in the accompanying drawings, described in the specification and particularly defined inthe claims terminatingfthe same. l
In the accompanying drawings, we have shown our invention in a form now preferred by us.
Figure l is a part vertical section and part side elevation of a complete radiator; j
Figure 2 is a transverse vertical section through a unit of the radiator;
Figure 3 is a transverse section on line 3--3'of Figure 2. l
A radiator made in units which are to be separable after assembly, must be clamped together in some way. Units of pressed sheet copper or like soft metalwould not stand such clamping but would collapse or would leak at the joints. Thus our invention is concerned with the provision kof means whereby such units of thin soft metal may be so clamped together that they are readily separated, and so that` they4 will not collapse under suliicient pressurev to hold their joints tight.
The units are shown as composed of two halves l and l0. These halves are, in general, alike but reversed, and the units areV shown as providing a central aperture 11 deiining two vertical columns l2; thus the units have inner and outer margins which must be secured, andthis securement ofthe two halves is conveniently accomplished by a double crimp orlike joint, indicated` at 13,
`this being common in sheet metal working,
and being capable of accomplishment by the use of tools usually readily` available. Thus the nested halves of" a great number of units may be shipped in a small space prior to assembly into the units, and conveniently assembled at their destination.
In assembling them, spacers 2 and 3, preferably in the form of apertured rings, are
interposed between the two halves ofa given unit. It will bc understood` that the halves of the units are apertured, the apertures being in alignment and affording communication between the several units. Theseapertures 14 and l5 are surrounded by the spacer rings 2 and 3, respectively, the rings lying just outside of the apertures, and when assembled in a radiator delining transverse '2U and SO' in the rings 2 aad respectively.;
One of the halves, as l0, may he provided with a-niale flange 17 Which projects within the aperture l5 ofthe adjoining` unit, that is, the aperture in the half" l of this adjoining unit.` Preferably the flange projects sufficiently that it engages the inner periphery of Ithe spacci' ring' o Within this adjoining unit, thus serving4 to maintain this ring` in' position..` ln this the sei/'eral spacer lrings may beheld in position, not only by the frictional grip of the two halves, but in additionby the positive action of the flanges 17,
At the ends of the radiator nieans are provided for closing the ends of the ` transverse channels 22 and 33 at to) and bottom, respectively, formed by the aligned spacers 2 `and At the top chamber caps l and t0l may be provided, the cap l having a male flange el fitting Within the tern'iinal spacer 2 to position it, and being iuteriorly threaded as indicated at e3, for the reception of a clamping rod l2 which extends through the channelQQ. t The other end of the channel 22 is closed bya cap 40, likewise threaded as indicated at t, for the reception of the end of the clamping rod 42, this cap e() ftting over the flange le of the terminal unit. A filling opening` Zl5 may be provided in this cap 4G, normally closed by a screnfed-on cover-47, and a safety valve indicated at i6 may be received in the cover 4;? connnunieatingwith the fillingq openinga l5 to control the pi'essiiire Within the radiator. lt will be noted that the top of the cover l? is dished slihtly, whereby it Will catch and retain VWater `ofcondensation dripping from the relief' `valve e6, this Water subsequently evaporating.
At the` bottoni of the radiator We provide caps 5 and 50 corresponding to the caps 4;
and el() and `connected by a series of clamping rods" 52 extending,1 between the caps 5 andwO, but preferably spaced outward of the airis of the" channel 33. As shown, the rods 52 are received within bosses of the cap 5, theirk other ends extending through the cap and receiving' clamping; nuts 54l exteriorly thereof. W ith these caps 5` and 50 may be associated the means for supporting the radiator and permitting its `Incweinent from place to place. rllo this enf Wehave shownsoclzets 58, provided for the reception of the shanks 8O of casters 8, the rings carryingthe `soclrets 5S beingformed integral-ly `with the respective caps 5 and 50.
Preferably the cap formed of tvvo parte, the niain portion beingv formed as a ring; upon which is secured a liL it cover 5l to close the end of the ring'. e prefer also thzrt'nieans` such as the casing 60, be provided and attached to the ring 5 for the support of a switch Sl. The lead Wires 62 extend to an aperture 55 affording communication betwecnthe switch casing (i0 and the interior of the ringV 5.
lt will be noted that the clamping rods 52 are angularly spaced und. in effect, form a cage Within which is received a tube 62 for the reception of a heating element, generally indicated by the numeral 6, and to Which the lead Wires (S/fare connected. rlibe tube 622 is closed at the end correspond,ing to the cap 50, but is fianged as is indicated at 62 at its other end, and this end is left open. rllo retain the vtube in place and to prevent leakage past its open end, collar A56 is threaded Within the ring 5 to clainp the flange 63 between itself and a shoulder 57 of the ring.
lf it is deemed necessary to indicate the depth of Water in the radiator, a Water glass 7 may be employed, the fittings 70 and .'Z'l beine threaded through the Column 12 of a terminal unit into a plate @soldered or otherwise secured to the insideof this column. Such a plate may be secured to the half unit l() prior to the assembly of this unit with a half' section l to forni the ooinplete unit.
lllhat vte claini as our invention is:
l. e. multi-unit pressed nieta-l radiator construction, each unit comprising ,compleu inental halves permanently joined about their margins, and having aligned apertures inward thereof, a soacer ring, interposed between the two halves of a unit, surrounding the apertures, one half only of each unit having` a flange surroiu'ulin, the aperture and projectable to be received within the aperture of the adjoining; unit to align. the units and to directly engage and align the spacer therein with the spacer Within the first unit, and means for clamping the several units together in the line of the apertures.
2. lu a rtu'liator, in combinatiim with a plurality of' units having aligned apertures, a cap closing the outermost aperture at one end of the radiator, a rino1 closingf the aperture at its other end, a j ilnrality of clainping rods extending betueen said cap and said ring, and, arranged aoout the axis of the aligned apertures, a tube open. at one end, andL having its open end received Within the ,collar and' its closed end supported. by said rods, and means for securing, the open endof the tube in non-lealting'relation to the ring.,
