T0 all whom, it may concern.-

Beit known that I, JOSEPH .HENRY RICKEE, a citizen of the United States, residin gat Lock Haven, in the county of Clinton andyState of Pennsylvania, have invented certain'new and useful Improvements in Tube or Section Boilers; and I do hereby declare the following Vto be a full, clear, and exact description of lvery rapidly and easily and as easily puttogetheragain, so that it can be transported rapidly and with facility fromplace. to place; to permit any tubeto be separately detached andreplaced or repaired as necessary, and to allow the boiler to be thoroughlyand quickly blown o or ushed from the steam-dome downward.

imposed on said furnace.

-The boiler, as hereinafter described,.is of quite `simple construction, very effective, and can be constructed cheaply.`

VIn the accompanying drawings, in which 6 is a detail perspective view of two pipesI and the end sections to which they are attached, and illustratingjthe construction of the boiler. Fig. 7 is a detail in section of one of the sections of the head,the tube, and means for securing it in thehead.

Referring to the drawings by letter, A'designates the upper part of a furnace of any suitable construction, and B designates 4a tube-boiler embodying the invention supe-r- The vertical end walls or heads C -C of said boiler are com-l posed of the cells, steam chambers or sections c c,-respectively,l each of theA inner of said sections having horizontal upper.. and lower edges and parallel side edges inclined, vas shown in`Fig. 3, till near the said upper and lower edges, when said edges rise and descend vertically; but each of the outer of said sec-` tions has its outer edge vertical. This construction, as seen in the said flgu're, permits the sections to be placed together to form a rectangular wall.V By this peculiar structure each section is of substantially the Same size, and each one, though matched and closely fitted to is separate from the other ones adjacent. There is thus insured not only a peculiarly strong and compact structure, but a uniform and regular ow throughthe entire system of sections, heads, and tubes,&c.

The sections, when in place, are bound to-` gether by the lower and upper manifold D D', respectively, at opposite ends, and the upper and lower cross-bars or supports` d d',

each of which is vertically opposite its manif' fold. The vertical tie-bolts E, which pass through the projecting ends of said manifolds and cross-bars, are secured by nuts e,

In the arrangement of the manifolds and cross-bars Iam governed by the number .of horizontal rows of tubes. Wherean uneven number is used, asin the drawings, the manifolds Iwill come at opposite ends, and where an even number is used they will come at the same end. The position of the crossbars will of coursebc changed in like manner. f

' F F are Vsteam-boiler tubes extending 'be- ,tween and connecting the'chambered end walls C C', each section `c c having the adjacent ends of two of said tubes connected to and opening into it. The ends of the tubes are held in place by the following means: Each tube F has its ends rabbeted at f4, so that one end ts into and abuts against a section-chamber c of one head andithe other end in like manner fits into and abuts against a section c of the head at the other end of the boiler, a metal gasket or packing f3 fitting between the rabbeted end of each tube and its abutting section. Each tube end is provided with a circumferential in! standing rabbet f, Figs. 4 and 5', vhaving the IOO sions f2 on a line on the inner face of said-f flange land at right angles to said notches.

The flange f4 at the end of 'each tube insures the snug fit of the tube in its appropriate hole c2 in the section to which it belongs.

By having only two tubes enter each seetion there is secured a perfectand evenlydistributed circulation through the tubes, sections, &c., since there is but one inlet and one outlet for each section; and by this construction not only is a perfect and even circulation obtained throughout the entire structure, but in ushing or blowing off each tube and each section is sure to have the full force Dass through it, so that the result attained is a complete cleansing of the boiler.

G is a T-shaped bolt having the shank g threaded at its outer end and the oppositelystanding'arms g g at its inner end. The said shank passes through openings in the walls of the adjacent chamber or section c or c', and in a washer y?, preferably convex on its outer surface, and is engaged by a nut g3 to the outer side of said washer, a suitable gasket or packing q1 being interposed between the section and washer. In fitting the tube F in place the notches f of the flange f are passed over the arms g of the bolt, and the bolt is then given about a quarter-turn, so that the end of said arms will fall into the depressions f2, and the arms of the bolt will hold against the inner surface of the flange and the tube will bind against the section with which it communicates, the nut g3 of course being turned up to make it bind as tight as desirable, the packing or gasket f3 aiding to insure the proper tightness of the joint.

At any time when necessary for repair or other purpose any one or more of the sections of either head can be very easily and quickly removed and replaced. This feature of easy removal and replacement of the several parts of this boiler is one of very great value, rendering the boiler very serviceable and durable, as well as in the long run very cheap.

Each chamber or section c of the heads has the adjacent ends of two tubes F thus connected to it; but the opposite ends of the said two tubes are connected to different chambers or sections, so that any tube F mayhave both its ends detached, and may be removed from the boiler for any necessary purpose by detaching the washer, nut, &c., on the outside end of said tube and the gasket and washer at end of the other pipe in the same section, when one pipe and one section can be removed,while the other section, to which it was connected, will be stayed by the remaining tubes. This is clearly illustrated in Fig. 6.

The upper row of tubes F have each one end secured to the manifold D by the same means as the tubes are secured to the sections, their opposite ends being secured to the upper row of sections c', while the lower row of tubes have each one end similarly secured to the manifold D and to one of the lower row of sections c.

H is the steam-deine, preferably in the form of a horizontal drum or hollow cylinder and connected on the under side at its ends by pipe I to the center upper tube F and the equalizing steam-pipes I from the outer set of tubes which enter at the crown and above the water-line. In the drawings these pipes are shown at each end at thc boiler-namely, the central connecting-pipe and the outside equalizing-pipes. The discharge or blow-.olf cock Z is shown at the lower end of thel boiler.

In blowing off the proper cocks are opened and the water is forced fromthe dome through the manifold, heads, and pipes downward in a ziefzafr flow elfectuall removinfT with it all b C J C sediment, mud, and deposit of every kind.

The tubes F are preferablyinclined slightly downward in the direction of the down fiow of the stream in order that the latter may more easily clean them.

It will be obvious to all skilled in the art to which this invention belongs that by means of this invention,as above described, the boiler can be made as large or as small as may be desired by merely increasing or diminishing the number of sections in each head and tubes to correspond, because when the boiler is increased in size the added sections fit to and match with those already in, and when decreased in size the remaining sections will fit and match together.

Having described my invention, I claim-` 1. Asectional steam-boiler having its rectangular heads composed of independent closely-fitting sections or chambers, as described, combined and connected with tubes in such a manner that each section has two pipes connected with it, but which two at the opposite ends are connected with different sections, whereby the llow upward or downward is regular and even through the entire system.

2. In a tubular steam-boiler, the combination of the heads C- and C', respectively composed of the closely-fitting sections c c, the' connecting-tubes F, the dome Il, and pipes connectingthe same to the tubes, and the tie-rods E, manifolds D D', cross-pieces d d', and means for securin g the sections and tubes together, all in theV manner and for the purposes set fort-h.

` 3. In a tubular steam-boiler, the combination of a d rum-shaped stealn-dome above the boiler, the end walls or heads composed of the closely-iitting sections, the tubes connecting the sections at opposite ends and intercommunicating from top to bottom through said sections, and the equalizing-pipes connecting the dome with the top tube of each intereommunicating series of tubes and sections, substantially as specified.

4. In a stealn-boiler, the combination, with the walled chamber or section forming part of an end wall or head, of a steam-tube rabbeted at its ends and fitting into and against said chamber or section and provided with a circumferential inward-standing flange notched at opposite points, the T or bolt hav- IOO IIO
