SECTIONAL BOILER.

SPECIFCATION forming part of Letters Patent No. 366.248, dated July 12, 1887.

Application filed May 14, 1887.

To all whom it may concern.-

Be it known that we, CHARLES PLAxToN, of the city of W'innipeg, inthe county of Selkirk, in the Province of Manitoba, Canada,

plumber, and JOHN PLAxToN, of the town of Barrie, in the county of Simcoe, in the Province of Ontario, Canada, plumber, havejointly invented certain new and useful Improvements in Hot-rater Sectional Boilers, ot' which the 1o following is a specification.

rlhe object of the invention is to design a simply-constructed hot-water sectional boiler in which the water will flow to and fro through small compartments, each compartment arranged in the furnace and practically sur rounded by the flames, so that it shall be quickly heated and extract to the fullest extent possible the heat of the flames; and it consists of a series of sections extending from the zo firepot to the top of the boiler, each section having a series of hollow projecting fingers extending across the furnace, a dividing-pan tition being placed in each finger, so as to separate the water flowinginto the bottom side of the linger from the water flowing out of the top side of the said finger, the sections l being arranged in pairs opposite to each other,

the lingers of one section projecting between the ingers of its opposite mate, the whole 5o being arranged and constructed substantially as hereinafter more particularly explained.

Figure l is a perspective view of our improved furnace with one of the sides removed to expose the interior arrangement of the iingers. Fig. 2 is a vertical cross-section through the line ac y of Fig. 1. Fig. 3 is a sectional detail of one of the sections.

In the drawings, A represents a series of hollow vertical sections, each section being provided with ahollow finger, B, projecting across the furnace, as indicated.

It will be noticed that the hollow sections A are arranged in pairs opposite to each other, the ingers of one section extending between 4.5 the fingers of the opposite section, forming a zigzag ilue, O, extending from the fire-pot D to the top of the boiler, where the smokefiue E is located. Consequently the flames and heated gases ascending from thefire-pot D 5c practically surround each of the hollow fingers Serial No. 238,248. (No model.)

B, and as each of these lingers contains but a small body of water the effect of the flames is immediate and effectual.

Each of the sections A may have an independent inletpipe, F, and an independent 5 5 outlet-pipe, G, but,if desired, chambers at H and I may be formed, so as to connect all the sections A together at their top and bottom, it being merely necessary to form suitable joints between each section. The water which enters the inlet-pipe F passes up through each section A, but in doing so must flow through each of the fingers B belonging to its respective section, a partition, J, being placed in eaehfinger B for the purpose of separating the water entering the nger from the water flowing back out from it.

A boiler constructed of sections formed in the manner described will be very cheap to produce, as there is practically no fitting re- 70 quired, the numberof sections required being arranged and secured together by the front and back plates, K, which are secured together by suitable bolts extending from one plate to the other.

It will be seen that the size of the furnace may be increased or decreased, as required, by

simply adding additional sections or removing such as are not wanted.

As the action of the flue O will naturally have a tendency to cause a stronger upward draft in the rear of the furnace, immediately below it we place a slanting partition, M, by which partition we cut oft' the fine immediately next to the rear section, and thereby equalize the draft through the entire furnace.

It will be noticed that the tlues O may be readily cleaned by simply removing one of the plates, as shown in Fig. l.

Vhat we claim as our invention is- 9o l. A hot-water boiler composed of a series of hollow sections, A, having horizontally projecting hollow lingers B formed on each section, which sections are arranged in pairs opposite to each other, so that the iingers of one section shall project between the iingers of the section opposite to it, forming a zigzag tlue, C, substantially as and for the purpose i specified.
