SPECIFICATION forming part ci Letters Patent No. 359,105, dated March 8, 1887.

Application filed December 2S, 1886. Serial No. 222,773. (No model.) Patented in Canada May 17, 1886, No. 24,079.

To @ZZ whom t may concern,.-

Be it known that l, ARCHIBALD SPENCE, of the city of Montreal, in the District of Montreal, and Province of Quebec, Canada, have invented new and useful Improvements in Tater-Heaters; and I do hereby declare that the following is a full, clear,.and exact de seription of the same.

This invention has reference to an improved construction of sectional boilers or waterheaters of the class used in connection with a system or systems of circulating-pipes, by means of which the heat of the water or steam is circulated and distributed as desired, to reduce the cost and labor of such heaters in their construction, and give a ver y effective heater.

The features or combination ot' parts which form the present invention will be hereinafter set forth and claimed.

In the drawings hereunto annexed similar Figure lis a side elevation of a sectional boiler or water heater embodying my invention. Fig. 2 is a front elevation ofthe sections ofthe boiler or water-heater shown in Fig. l. Fig. 3 is a plan of the boiler or water-heater shown in Fig. l. Fig. 4 is a plan of the sections F of the boiler or watenheater. The sectional part ot' this figure is taken on line x, Fig. l. Fig. 5 is a section at line x, Fig. 3, of the casing D and of the sections E, while the section of the sections F is shown as taken on line i Fig. 4. Fig. 6 is an elevation of the faces of the projections es. Fig. 7 is an elevation in part ofthe casing D and in part a section taken at line y, Fig. l. Fig. S is a side elevation of a modification.

Letter A is an ordinary furnace, the outline of which only is shown. It is preferably a water-cased7 furnace, but not necessarily so. If a water-cased furnace, B. is the water-inlet pipe to it and Gis the water-outlet pipe from the water-casing to a casing, D, which connects with all the sections E and F, used in forming the sectional portion of the boiler or water-heater. The sections E and F are to some extent ot' two different forms or constructions, and are set together or built alternately-- at the top a section, E, next a section, F, again a section, E, under it a section, F, and so on for Whatever number of sections may be employed. This alternation is shown in the drawings.

The sections E and F may be made of any desired shape in plan. As shown, they are circular. The sections E consist of a water or double casing, c, provided with an enlarged upper circumferential iange, c', alower ilange, e2, ot' proper size to iit Within the flange c', a projection, e", having ports el and e5. These lsections E are also provided with a central opening, F, and a diaphragm, f, uniting with the projection e3, and extending to and uniting with the wall f of the opening F. The sections F are the same as the sections E, above described, in so far as being formed of the casing c, with enlarged iianges c', ilange ci, and projections e3, and these parts are the same sizes as in the sections E, but the sections F are provided with a number of openings, G, situated near the outer edge of the sections, and in this case the diaphragms g are carried a greater distance part way across the sections, as shown in Fig. 4.

H is a frame, to which is attached a sweephole door, h. IVith the exception of thelowest section of whatever number may be used, the flange e? does not extend completely around the sections; but where the opening of the frame H occurs the portion of the iiange eAll is omittted, as shown in Figs. 2 and 5, thus leaving openings 7V', to reach in and clean out any soot or ashes which may collect upon the u pper inner surfaces of the sections.

The casing D consists ofa closed tube having a length somewhat greater than that of the height of the sections E and F when built together, as shown. It is provided with an inner diaphragm, d, dividing, with the diaphragm d, the space into two parts, d and d2, as shown in Fig. 7.

In the face I of the casing D ports d4 are formed, agreeing with the ports c of the sections E and F, and ports d5, agreeing with the ports e5 in the said sections.

The diaphragms d and d are integral with the casing D, and in the diaphragms d are formed enlargements t', having openings z" for bolts 7c to pass through and screw into the center of the projections c, screwed holes being formed in the projections for this purpose.

The manner of tting up the sections and IOO casing is to lay or build together the sections E and F (whatever number may be required) in proper order, with the projections e3 agreein g as nearly as can be. Vhen so built, they are firmly clamped or bound together and put on a planing-machine, and all the faces of the projections e dressed off to a true surface in one and the same plane. The face I of the casing D is also planed off true and laid upon faces of the projections e:i and adjusted so that the ports e", e5, (1*, and d5 agree. The bolts k are then put in and the casing and sections united together, after which the clamps, 85e., by which the sections have been held together during the said operation of planing, are cast off and the sections are ready to be united with the furnace A, which will be provided with a flange, L, or other ordinary means for forming a properjoint with the bottom ange, e?, of the lowest section.

If the furnace A is not a water-cased one, the pipe C will not connect, as shown in Fig. l, but Will unite with the return of any ordinary system or systems of heater-pipes usually connected with heaters of this class, as shown in Fig. 8.

L is a pipe, one or more of which may be attached to the upper part of the casing D, to connect any desired number of systems of heater-pipes therewith.

L2 is any suitable flue or chimney by which the products of combustion are carried off. These,arising from thefurnace A, are compelled by the situation of the openings F' and Gr to travel by the circuitous route indicated by the arrow in Fig. 5, thus causing a large amount of very effective heating-surface.

The Water entering the casing D by the pipe C in the part d passes through the ports d* and c* into the sections E and F and circulates through them, as indicated by the arrows shown in Figs. 3 and 4, the heat of the water being raised while so doing, and by the ports c5 it passes into the part dt of the casing D to the pipe L for circulation.

It will be observed that by this arrangeinent of the sections E and F they form a casing which incloses the smoke and products of combustion.

What I claim, and wish to secure by Letters Patent, is as follows:

l. rlhe combination, with a furnace, of the sections E, having llanges c and c2, openingsv F, diaphragms f, projections e3, and ports e* and e5, sections F, having flanges e and e, openings G, diaphragms g, projections e3, and ports e* and e5, and with casing D, provided witlrports d* and di", and diaphragms d d3, also provided with inlet and outlet pipes, as described, the whole united and operating substantial] y as described.

2. The combination, with a furnace, of the sections E, having openings F', projections e3,

havin@ orts e* and e5, and dia `ihrafrms sec' o 1 o 7 tions F, having openings G, projections c3, f

having ports e* and c5, and diaphragms g, with a casing, D, connecting the ports in the manner described, and provided with inlet and outlet pipes, as described, the Whole substantially as set forth.
