HEAT-RADIATOR FOR STOVE-PIPES.

Specification forming part of Letters Patent No. 50,069, dated September 19, 1865.

To all whom it may concern Be it known that I, N. F. GOODRIOH, of Meriden, in the county of New Haven and State of Connecticut, have invented a new and ImprovedHeat-Radiator for Stove-Pipes; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical or longitudinal section of my invention, taken in the line a: w, Fig.2; Fig. 2, a transverse section of the same, taken in the line y y, Fig.

Similar letters of reference indicate like parts.

Thisinvention relates to a new and useful improvement in a heat-radiator for stove-pipes, for which Letters Patent were granted to I. L. Holmes, August 30, 1864.

The radiator of Holmes consists of two conical chambers connected by a series of pipes, forming in the aggregate quite a large heatradiating surface. This radiator answers a good purpose, but it has one defect, to wit, no means by which a direct draft may be obtained when required-as, for instance, in kindling a fire, and at times when, owing, to the direction of the wind and from other causes, the draft is sluggish and insufficient to insure a rapid combustion of the fuel within the stove.

My invention is designed to obviate this difficulty; and to this end it consists in providing the radiator with a central pipe of larger diameter than those surrounding it, and providing said central pipe with a damper, all being arranged as hereinafter set forth, whereby a di rect draft may be obtained through the central pipe whenever required, and an indirect draft through the smaller pipes when the radiation of heat from the device is required.

A A represent two chambers ofconical form, communicating with each other by means of pipes B, placed in the form of a circle between A A, as shown in Fig. 2. The two chambers A A are connected by a pipe, C, which connects with the centers of the larger ends of A A, the pipes B, which are considerably smaller than C, surrounding it. The pipe C is provided with a damper, D, and a damper, E, is placed within one of the chambers A.

The device is connected with the stove-pipe by having its joints fitted on the smaller ends of the chambers A A; and itwill be seen from the above description that when the damper D is closed the products of combustion willpass up through the small pipes B, as indicated by the arrows l, and a large heat-radiating surface obtained. This, however, is rather an indirect draft, and in cases where the combustion of the fuel in the stove will be too much checked, or when a strong draft is required-as in kindlinga tire, forinstance, the damperD of pipe C is opened, and the products of-combustion will pass up directly through C, as indicated by arrow 2. Thus, by this very simple arrangement, the patented device of' Holmes,previously alluded to, is made perfect.

I claim as new and desire to secure by Letters Patent- 1 The central pipe, C, provided with a damper, D, in combination with the pipes B and chambers A A, all arranged substantially as and for the purpose specified.

N. F. GOODRICH.
