@Asis-rave.

'.ihe` Schedule referred to in these Letters Patent and making part of the same.

county, and State ot' New York, have invented a new the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make anduse the same, reference being had to the accom# panyng drawings, forming part of this specification, in which- Figure 1 represents a vertical longitudinal section of dicated by the line a: x, fig. 3.

Figure 2 is avertcal transverse sectionof the same, Ehe plane of section being indicated by the'line y y, Figure 3 is a.V horizontal section of the saine, taken on the planeot' the line z z, iig; 1.

Similar letters of reference indicate corresponding parts. y This invention has for itsobject to construct a gasstove with' an extended radiating surface, and with proper. air-channels, `so that with a comparatively small amountof heat .the air in 'an ordinary-sized room can be' properly warmed; i

The invention consists in the construction of annular air-passages, arranged within and around annular gas-passages, and in thev connection with each other of scribed.

A, in the drawing, represents a tire-box, of cylindrical or other equivalent form, adapted to receive the gas or oil-burners, from the flames of which the requisite heat is to be derived.

The box A is covered by a plate, a, which has only Four vertical pipes, Q, D, E, and F, diiering in around .the pipe B, forming annular chambers b, c, d,

same, whence they are conducted by a horizontal pipe,

g, into the upper part of the chamber' c,

From this chamber they are, through another transverse pipe, h,y which may be near the lower end of the vertical fines, conducted into the chamber e, whence ,they escape-into the smoke-pipe i.

The products of combustion, wliilepassing from the tire-box A to the smoke-pipe,;1no ve along all the pipes B, O, D, E, andi?,- and heat their surfaces. .l

Cold air entersthe lower end s 'ofthe chambers b d, through horizontal pipes jkrespectively, and is, while ascending in the chambers 1 d, exposed to the heatedsurfaces of the pipes B, O, D, and E, while the pipe.

F will heat the air surrounding theapparatus. Thus the heat of the burning gas or oil is almost entirely t utilized.

Itis evident that ythe number pipes on the iirebox may be varied, and that thereby the invention is applicable to heat-ers of greater or less extent.

Having thus described my invention,

I claim as new, and desire to secure by'Letters Patentand described.
