Svevia-PIPE DRUM.

Specification forming part of Letters Patent No. 47,887, dated May 23, 1 65 To all whom'it may concern.;

Be it known that 1,-THorrAsW1-IITSON, of

IVoodstock, i`n the county of McHenry and State of Illinois, have invented a new and Improved*Heat-Radiator for Stoves and I do hereby declare theiellowing to be a full, clear,

4and exact description of the same, reference. being had to the accompanying drawing'and .the letters oi reference marked thereon.

- -The nature of my invention consists in a novel construction of return-dues adapted for application to any stove now in use, by means of which a large amount of the heat which ordinarily passes into the chimney may be -radiated into the atmosphere pf the room, and

thus utilized.

. That others may understand the construe-,

tion and operation-or" my'iuventioml will particularly describe it.

A is the collar, ofl suitable size to t thelv end. E is the top of -the radiator, also divided into three parts by the partitions F, and is provided with the valve G in its collar, which is or' suitable size to tit'thc pipe -that is to' be placed upon it.

Between the base B and the top E are the pipes H II, I I, and J, and to increase the radiating-surface, the horizontal short and open pipes K K K are inserted, extending through from front to rear,.and open at each end.

apparatus, or the number or arrangement of Vthe pipes, may be varied as Well as its dimensions, in order to adopt it to any particular locality or circumstance.

The operation is as fol lows When the valve 'lV D is open, as shown by redlines in the figure,

the draft passes directly upward in the c lipecf tion of the red arrow, through the pipo- J, through the central passage ot E,past the valve G, and intofth'e main pipe, to the flue-oi-` the chimney. This rendersitconvenient when lighting` the ire, as it lis often difficult to induce a draft through a cold tortuous passage, whereas it maybe readily'induced through a straightone.A lf, however, itis desirable to increasc the heat in the room, the lower valve, D, is closed, as shown in the drawing, andthe current of heated air is then deilected .and

forced to divide and ascend through the outside passage ok' B, throughthe pipes HH into the top E, Where the partitions F arrest its upward progress and A"force it to descend through thepipes I I into the Vinner chamber ofv B, from whence the passage is clear through the pipe J and valveG to the chimney. `'I his circulation is indicated by black arrows.` .It

will be seen that theshort transverse pipes K` will be continually bathed in heated air, and being open at their ends,`allowing a free cur rent through them from the atmosphere of the room, they will necessarilyr extract a considerable .quantity of caloric from the `heated air within the radiator. The valve 'G islmade somewhat smaller than the., diameterV of the pipes in which it isplaced, as it is not desirable to close completely the duct through which the products of combustion must pass? as in that case they will inevitably esca-pe lto some extent into the room.

Having describedmy invention, whatI claim A heat'radiato-r for use in connection with. a stove, consisting in a base, B, and top E, It is obvious that the external form of my provided with the partitionsY G and F, con nected by the tlues H and Jv and4 return-lines l, and provided with the valves D-and Gr, and

with or without the transverse pipes K, substantially as described. V
