I Letters Patent No. 100,013, dated February 22, 1 870.

. WATERfHEATfJR FOR GREEN-HOUSES.

The Schedule referredto in these Letters Patent and making partl of the eamo I I, S. E. GHUBBUCK, of Boston,'in the county of Suf` Nature and Objects of the Invention.

The nature-0f my invention relates to the particular arrangement ofthe heating andcirculating pipes, the object thereof being to secure au unobstructed, free, and positive circulation of the water, together-with an advantageous arrangement ofthe pipes relative to and within the tire-chamber. Figure l of the drawing is a perspective view-illustrative of the invention, in which a part of themasonry is broken away.

Figure 2 is a sectional view, showing the iire back or guard H,v&c.

A is the cold water or induction-pipe, which lies across the rear ofthe tire-chamber. y

The water may be admitted at either or at' both ends A A of this pipe. The arrows indicate it as admitte at the rightvof the drawing. v

From pipe A pipes B are extended forward, one at each side of the lire-chamber, above "or lpartly above the level of the grate.

A return-pipe, O,`is located over each .of the pipes B, and connected therewith at thefront;

At the rear these pipes C'return in like'manner by connection with pipes D still vabove them, and these again at the front return into the pipes E, which, extendingr to the rear, again connect with another transverse pipe, F, at the top of the rear partot' the lirechanlber.

The pipe F is the eduction or 'hotwater pipe, which may be extended by connections 'from either orv both its-ends in any direction or to any required distance, discharging or returning-again by connectingpipes to the cold-water pipe A.

The arrows indicate the' water as discharging to the right of the drawing.,

The systems .of'pipes B B, C C, D D, and E E are arranged longitudinally with reference to the lire- 'chamber G, each being elevated somewhat above tb'e other from pipe B upward, the pairs C C, D D, and E E Abeing each pair arranged nearer to each other as they are locatedhigher one than the other, the system completing or approximating to the form of an yarch over the grate vwithin the lire-chamber.

Where small capacity is required, the system of pipes maybe abbreviated and the pipes 0 C may return from the rear into a single central pipe made to extend `forward and join .to the pipe F F, which, in such a case,

, should be located for the purpose at the front instead of the rear, or the pipes D D may connect with pipe F at the front, or theymay return at the front into a single pipe, as E, leading to pipe F.

The system of pipes should be iuclosed in the firechamber, except the pipe A and the protruding-ends ofpipe F.

lhe pipe A may be partially protected from the heat by means of a {ire-back or shield H, (see iig. 2'.)

The described arrangement subjects theupperl pipes lto the more direct and intense heat, while all except pipe A A are surrounded with the heated contents of the fire-chamber.

The water in the upper pipes naturally, 'under the arrangement, becomes warmed rst, and as naturally' risesin the pipes from one to the next, giving place to the inilowing cold water from the pipeAat the bottom. l

As the'passage through the pipes from pipe A to pipe F is constantly upward, and the pipes, by their arrangement, become more and more heated during the ascent, the circulation receives no confusion from connteror uncertaincuirents, butimmediatelybecmes posit-ive and regular ou lighting the lire, and-may be continued indefinitely.

The pipes may be made of cast-ironor other material," and the, parts united with boltsand iianges in the usual manner.

Other material, however, as well as other well-known methods of uniting the parts may be used.

The lire-chamber may be constructed of brick or other material.

C Ict/im.

I claimthe-airangement, in an arched series .rising and converging in longitudinal alternations from front td rear and rear toi'ront', ot'a continuousp'ipe atei'ther side of the fire-chamber, substantially as described and Witnesses:
