Letters Patent No. 97,915, dated December 14, 1869.

stove-PIPE DRUM.

The Schedule referred toxin-these Letters Patent and making part of the same.

clear, and exactdescription thereof, reference'being, had to the accompanying drawings, and to the letters ,ot' reference marked thereon, in which- Figure 1 represents an elevation of theihe'ater. Figure 2, a View of the top and bottom of the cyl-' inder, the caps being removed.

Figures Sand 4 are perspective views of a planofthe upper and lower cups applicable to' the heater, the

' same asshown in fig. 1. Y.

Figure 5 represents the heater as used in-ahorizontalposit-ion. i I Figures 6 and. 7 are perspective views-of a'plan of the caps applicahletothe heater, the same as' shown I Figure 8 is a vertical section through th centre of the drum. i I 1. j

My invention consistsof a metal cylinder enclosing a seriesof air-pipes or ductsrforattachmentto the I smoke-pipe of iiiel-consuming stoves orfnrnace's, The smoke and heatfrom the:lattercircnlate in theannnlar space of the cylinder, and rarefythe air in th'e ducts, causing it to ascend'amhpa'ss into the room.

A, fig. 1,is the metal cylinder enclosing the airdncts B. These ducts-extend through the cylinder,

and are held in place by head'sj as shown in fig; '2, one

beingat ,each end of 'the cylindenithe central duct air ascends through them;

Acap, O, lS fittGdftO' the bottom of the cylinder, Ihaving' holes or inlets in; its inargin, 'fig. 4', through which the'cold air (represented by thered arrows on being the largest. Wheuthese ducts are heated the figh ii) passes into the chamber formed by thencap C,

and then into the duets. i

If it he required to. conduct cold air to the ducts from any given distance, tlre capC should be provided with one inlet, L,fig. 1', represented by dotted lines in its side.-. A pipe leading from the point enters this inlet oraperture L. l

To the top of cylinder is also fitted-a capfD, in

which is an openiug'or outlet, fig: 3, to allow the heated air,.represented by red arrow; ,on fig. 1, to escape, and the rarefied air issuing therefrom may he conducted by Thesecaps, at top and bottom, also serve to check the too rapid circulationof air in the ducts, beforeit has become highly rarefied, by forming chamber-1a diators of the two heads.

The smoke and heat (represented by black arrows) from the fuel-stove enter the annular space of the cylinder at its side E, fig. 1, at anyrequired distance from its bottom, and pass upward amid the ducts until they make their exit through the pipe F, in the circumference of the cylinder, near its top. i

Withinthe cylinder, extending midway across, ar two radiating plates J, section fig. 8, encircling the ducts, and' the one placed a short distance above the smoke-entrance E, the other-situated on the opposite side, a little below the smoke-outlet F.

These radiatingplates prevent the direct passage of the smoke through the cylinder A, and serve to distribute the heat around the air-ducts. y

In case the outlet smoke-pipe, with the radiatingplate below it, should be situated directly above the inlet smoke-pipe, it would be advisable to use a central radiating-plate, extendinghalf way across the cylinder from the opposite. side.

' The'contour of the cylinder may be round, oval, or any required sh'ape,or ornamented, or plain,and the air-ducts may be ofa size suitable to the circumference of thecylinder, and of any number, but much advantage will arise from the centre one being larger than the others, and the pipes proportioned to the area of the cylinder, due regard being hadto the passage of the smoke.

When required to be used in position, as represented in fig. 5,the caps H and 1,..figs. 6"'and 7, would be suitable plans to use for forming the proper circulation of air through the ducts.

The tunnel, or conical-shaped leg G, can be made a. suitable height to be used with the heater, the upper end pressing into the connection K.

By the use of this invention, th e cold air from the floor of the apartment is drawn ofi', heated, and sent .upward, thus conducing to the circulation of the air and ventilation of the room.

I am aware that hot-air furnaces have heretofore beenconstrncted, having fines and air-spaces similar to those herein described;

My invention, however, relates to the construction and arrangement of fluesand air-spaces comprising a separate and distinct apparatus,-attachable, at pleasure, tic-any ordinary heating or cooking-stove, to meet the varied requirements of the season.

Ithereforeclaim, as my own invention- The radiating-drum herein described, consisting essentiallyof the cylinder A, with smoke-inlet and exit-- pipes E 1 air-pipes B, perforated beads C and 1), or

equivalents, and. deflectors J J, constructed, arranged,

and operating as and for the purposes setgforth.
