IMRovEMnN'r 1N HEAT-RADIATOR.

Tha Schodule referred ton; 'these Letters Patent and making partzoi the sama. i

Be it known that I, WrLLiAM B. OHOA'rE, of Galt, Canada lVcst, have invented a uew'aud useful linprovement in Heat-Radiators; and I do hereby declare that the following is atull, clear, and exact description thereof, which will enable thosev skilled in the art to make i-nd use the saune, reference being had to the accoinf penying drawings, tbrniing part of this specification. This invention' relates to n new and useful in'ipro\'cnient in radiators for heat, to beattached to stoves, and used in all situations where they may serve the purposes for which they are intended. l

And the invention consists in the combina-tion, with a radiator of serpentine thun, ci' the method of placing the lianges ou the end-plates, and in depressing the iiue. of the radiator after the curves or turns, 'so as to forni a series of diving-hues.

The drawing, Figure l, represents a vertical seetional -elevation of my radiator attached to a stove, and connected with a, stove-pipe, the stove and the stovepipe being shown in red color in the drawing.

'Similar letters of reference indicate correspondingr pants.

A represent-s the radiator, of serpentine shape, o1' formed into e succession of curves or turns, as seen in the dra-wing.

B represents stays, which are attached to each ofthe horizontal sections of the serpentine tine or radiator, for supporting it and keeping it in place.

The 'end-pieces G (l ol" this radiator may be mede ot' The radiator itselt` is runde of sheet-iron.

The heated products of combustion, in passing up through this radiator, willimpinge against the upper surface, and the heated current will repeatedly change its position during its progress, thereby exposing every portion of the rnoving current to the heat-radiating sur fece. l

This radiator isaJ attened tube, as seen in the top view, Figure 2, audit will be seen that, with the few curves .and turns shownin this example 'of my inven.`

tion, a very extensive heat-rediating-surfce is presented to the nir.

The importance of this feature in al heat-radiator becomes apparent' when we consider that nir will not heat nir, and that to heet kor warm 'the nir in a. room, every particle of air must be brought in contact with ,al heated surface.

A current is thus formed, setting-towards the radiator. The air, as it is heated by Contact with heated metal, becomes iareliedand illes upward, while the colder air rushes in to take its place. .y

` The 'heated products of combustion passing into this radiator are forced to pertwith their contained caloric,"

ot' the plates, are `not continuous or unbroken, but that Y a portion (that portion which forms theouter orlarge curve) is set inward on the plat-e, andthat the. part-'43T the flange f, which forms the inner 'and 'smell curve, and also the stm-ight portion of the tube, encloses the serpentine sides ofthe tube.

By this method of formation the corrugated sides are v much more easily managed in putting the radiator together, and much more easily kept in place, as they are not so much effected by the expansion and contraction.

byl heat.

The end-plates of the radiatorE can bemost rel ily made of enst-iron, and they are held'together (with the serpentine or corrugated sides between them) by transverse rods with screw-nuts, which pass through holes g, as seen in the drawing.

A It will be noticed that the outer curves of the serpentine tube are depressed, so that each certain extent) a diving-flue.

The tendency of hen-t to seek the highest portion oi' avhorizontal tube will produce a cha-nge in the current at every turn, and vthat change is .1nade more perfect,

and all central current more completely destroyed, by fcompelling the current to descend'atter'every turn.

Having thusldescribed Iny invention,

' What I claim as new, and desire to secure by Letters Patellis, is- Y l. In combination' witha radiator of serpentine forni, the method of placing the flanges al and f on theeud plates, substantially as shown and-described.

2. Depressing the line of the radiator after the curves or turns, so as to form n series of diving-fines, substantially as and for the purpose set forth. v
