IMPROVEMENT IN HEATERS.

Specification forming part of Letters Patent No. 159,479,

dated February 2, 1875; application filed January 6, 1875.

To all whom it may concern Be it known that we, STERLING D. TUTTLE and BENJAMIN F. LARSH, both of Eaton, Preble county, Ohio, have invented a new and useful Heater, of which the following is a specification:

Our invention consists in an improved form and arrangement of air-heating attachment for stoves, the first part of our invention consisting of two air-heating pipes or cylinders, of which one is surrounded by the other, which surrounds the smoke-pipe, said cylinders having suitable inlet and exit passages for air, which are rendered capable of regulation by means of covers or registers, said cylinders having also intercommunication by means of one or more cross-pipes, which traverse the annular interval or smoke-passage between the said cylinders.

In the simplest form of our invention the smoke-pipe is so arranged as to be applicable direct to the collar either of a cooking or a heating stove, while the more complex form of the apparatus is adapted for attachment to a cannon or cylindrical heating stove. For this latter purpose the lower end of the smokepipe proper is fitted upon a short neck, that projects upwardly from a dome-shaped drum, which is fitted within the upper end of a cannon-stove, the top plate or cap of the latter having been previously removed. This domeshaped drum has secured to it an annular flange or rib, which prevents said drum descending too far into the cylindrical stove to which itis fitted, and which also serves to hold said drum and its superstructures in a truly vertical position. Occupying an axial position within this drum is a vertical pipe, whose lower end is closed with a thick baffle-plate, which prevents the entrance of fire and smoke to said pipe, and also deflects the products of combustion, and forces them outward against the sides of said dome. The upper end of this vertical pipe is coupled to the central pipe of the heater, in order that there may be a free circulation of air within these united tubes, the air entering them through a branch inlet, which projects laterally from the said vertical pipe, and passes through the side of the dome. This united central pipe may be carried up through the stove-pipe elbow, so as to conduct heated air into the upper apartments of the house or said pipe may stop short of the elbow, and may discharge the warmed air. through a suitable opening, directly into the room that contains the stove.

In the accompanying drawing, Figure l is an axial section, showing our heater (in its simplest form) attached to the collar of a stove, the registersbeing set so as to discharge the warm air through the outer drum of the apparatus. Fig. 2 is a similar section of the more complex form of the heater in position upon a cannon-stove, whose upper portion only is shown, the registers being so set as to insure a circulation of air through the central pipe or cylinder.

A may represent the collar of any customary heating or cooking stove; B, its smoke-pipe, which may terminate in a customary elbow, G, or be conducted directly upward. Suspended axially within the smoke-pipe is our interior cylinder orhot-air chamber or reservoir D, the same being closed at bottom by a bat'fleplate, E, the upper end of said reservoir being either closed by a plate, E, as in Fig. 1, or prolonged upward, as at E, Fig. 2, for the purpose of heating another apartment. One or more ducts or crosspipes, F, serve the double purpose of supporting the central hotair chamber, D, and of affording communications between it and a drum or external chamber, G, which surrounds the smoke-pipe in the manner shown. H are registered or closable passages or inlets for fresh air to the central chamber, D, and I are unregistered air-inlets to the external chamber or drum, G. J and K are, respectively, registered outlets for the chambers D and G.

The above-described arrangement of parts is susceptible of being operated in various ways to suit the user. Thus, by closing certain passages, J, and opening others, K, as shown in Fig. 1, the warmed air may be compelled to escape from the reservoir into the drum, and thence into the apartment; or, by arranging the passages as represented in Fig. 2, the air, entering the drum, passes thence into the reservoir, and so out. Moreover, our heater may be adapted to discharge either wholly into the room in which the stove is situated, or partly or wholly into another room, while the smoke-pipe may be conducted directly into the flue or chimney, or may be extended upward, and may, in another apartment, traverse a second heater of similar form and arrangement to the one above described.

'In the more complex form of our heater (shown in Fig. 2) it will be noticed that the lower end of the smoke-pipe B is fitted around a short neck, 1, that projects upwardly from the sloping top L of a cylindrical chamber, M, which has an annular flange or rib, m, around it, to hold the heater erect, and in the proper relative position on the stove-top N, without.

descending too far within the same. If preferred, however, that portion of the chamber M which is exposed above the stove may be of a hemispherical or dome shape, instead of having the cylindrical form shown. Secured in an axial position with reference to this dome-shaped drum or cylinder M is a vertical pipe, 0, which is fitted to the lower end of the hot-air reservoir D, said pipe being provided with a lateral pipe or inlet, H, and a damper, h. This damper may, however, be omitted, and an external register substituted therefor, as shown by dotted lines at the outer end of said branch pipe.

P is a thick casting or deflecting-plate, that effectually closes the lower end of pipe 0;

and this plate maybe perforated to admit a cold-air pipe, extending horizontally a suitable distance, and thence vertically to the top of the dome, as indicated by dotted lines.

The drum G may extend any suitable distance longitudinally of the stove-pipe B. One or more pipes may be arranged to convey heated air from the drum G to a remote apartment, as indicated by dotted lines at the left of the smoke-pipe in Fig. 1.

We claim as new and of our invention- 1. In combination with a heating-stove, the central air-heating chamber, D, within the smoke-pipe B, having one or more tubular supports, F, forming communication with a drum, G, surrounding the smoke-pipe, said chamber and drum having suitable inlets and outlets, as and for the purpose set forth.

2. The dome L I, having supporting-flange m, and forming chamber M, and supplemental pipe 0, having inlet H h, in combination with chamber D, stove-pipe B, supporting-tubes F, and drum G, for attachment to a heatingstove, as and for the purpose specified.

In testimony of which invention we hereunto set our hands.
