EPECIFIGATION forming part of Letters Patent No. 545,269, dated August 27, 1895.

Application filed December 26, 1894. Serial No. 532,929. (No model.)

To aZZ whom it may concern:

Be it known that I, BARZILLIA J. COLLER, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Boilers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention consists in the peculiar con struction, arrangement, and combination of the various parts of a boiler for use as a steamgenerator or a water-heater, and particularly in. the construction of the heating and circulating tubes, whereby I accomplish a rapid circulation and obtain a maximum efficiency from the heat of the tire; also whereby the boiler is made in like sections, whereby the expense of manufacture is lessened, and whereby the size or capacity of the boiler can readily be changed by adding or removing the desired number of sections of the heatingcoils, and, further, whereby the water-circulating coils and headers may be thoroughly cleaned without dismantling the boiler, all as more fully hereinafter described.

In the drawings, Figure 1 is asectional elevation of a boiler embodying my invention.

Fig. 2 is a side elevation thereof, showing the casing in section. Fig. 2:) the horizontal headers. Fig. 4 is a vertical section on line so so of Fig. 2. Fig. 5 is an enlarged detail section of the end of one of the inclined manifolds.

The boiler is provided with suitable setting is a plan view of and inclosing casing and grates of any known necting-pipes C. These headers are tapped on their upper face to receive the lower end of the risers or nipples I), one for each secthrough the universal manifold H.

tion of the heating-coils. Each heating-coil comprises the parallel manifolds E and E at top and bottom, which manifolds are inclined from the riser D upward toward the other end. These manifolds on their inner faces are provided with two threaded nipples F, which are connected by the vertical circulating-pipes G, the whole section being substantially the shape of a rhomb or rhomboid, or whatI shall hereinafter call the rhombic sections. From the corner diagonally opposite that at which the riser D connects I form the outlet-pipe G, which connects, by means of the horizontal section G into the universal header H. The next rhombic section has its riser D connected to the left-hand header B and its manifolds E inclined in the opposite directions from the manifolds E, while its outlet-pipe and connecting-pipes G and G connect into the opposite side of the universal header H. These sections are thus arranged alternately the whole length of the horizontal headers B, or so many of them are arranged thereon as may be desired to make a boiler of the necessary capacity. The water circulation, therefore, will be from the two horizontal headers upward through the risers D into the manifolds E E distributed across the fire in an upwardly-inclined direction through these manifolds and vertically through the pipes G to the upper manifolds, and thence through the connections G G The upper manifolds E are provided on their upper surfaces with plugs I, opposite each of the pipes G, so that by removing the plugs these pipes may be thoroughly cleaned. The inclined headers E E are also provided with plugs J, which may be removed for the same purpose. In using this construction of boiler for a steam-generator I extend the universal headers H out through the front of the boiler, casing and connected into the top of the steamdrum K at one side thereof, as shown in Figs. 1 and 2, and the lower end of this drum I connect by the pipes L with extensions M of the horizontal headers B. In the connectious between the headers H and the drum and the extensions M and the drum I place valves N N, so that if it is desired to use but a single boiler of a battery the other boilers may be disconnected therefrom by shutting these valves without in any way affecting the operation of those remaining.

I deem it especially advantageous to connect the universal headers into the steamdrum at the top and side, as shown, for the water flowing off from those headers into the drum will strike the opposite downwardly-inclined face a of the drum and be deflected downward into the water in the drum, preventing its splashing upwardly into the steam and thereby increasing the moisture in the steam. I find that with this construction I maintain the steam much drier, Whereas heretofore these pipes have been connected into the steam dome in such a manner as to strike a vertical side and be deflected in all directions.

\Vhat I claim as my invention is-- 1. In a boiler,the combination of horizontal headers a series of rhornbic sections connected thereto at one corner each comprising a lower inclined manifold extending over the grates, a series of vertical pipes extending from the upper face thereof, the series extending across the boiler and an upper manifold parallel to the lower manifold and into which the vertical pipes lead, substantially as described.

2. In a boiler, the combination of horizontal headers on each side of the fire, a series of rhombio sections connected thereto at one corner, alternately to the opposite headers, and each section comprising a lowerinclined manifold extending over the fire space, a series of vertical pipes extending from the upper face thereof, an upper manifold parallel to the lower manifold into which the vertical pipes lead, outlet pipes from the upper end of the upper manifold, and a universal header into which said outlet pipes connect.

8. The combination of a multiple of fur naces, independent water circulating; pipes, or boiiers for each furnace universal headers at the top of each boiler, a common steam drum into which the headers connect, return connections from the drum to the bottom of each boiler, and valves in the universal header connections and in the return connections substantially as described.

4. The combination with the boiler comprising the side headers, the universal header at the top and connecting circulatingpipes between, of a steam drum having the downwardly inclined portion a and located at the front of the boiler, a return connection from the steam drum to the side headers, and a connection from the universal header to the steam drum entering; at the top on the plane of and opposite the downwardlyinclined portion a of said drum, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
