SPECIFICATION fermingpart of Letters PatentNo. 289,322, dated November 27, 1883.

Application tiled April 4. 1F83. (No model.)

`To all whom it may concern..- Be it known that I, JOHN W. VAN DYNE, of Brooklyn, in the county of Kings and State of New` York,`have invented certain Improvements in Steam-Boilers, of which the following is a specification. i

` This invention relates tothat class of steamboilers commonly termed Water-tube boil shall be reduced to the lowest possible degree.

. ers, and its object is to provide asimple, 1o

strong, and eflicient boiler in which provision shallbe made for the` most advantageous ciri culation of t-he Water and the free and unimpeded disengagement of the steam from the boiler, and in which the injury to the structure of the boiler incident to expansion and contraction arising from changes of temperature The invention comprises certain novel combinations of parts whereby these objects and results are secured.

Figures l, 2, and 3 are vertical transverse n sectional views, representing various features and modications of my said invention, and

taken in a vertical plane corresponding to that indicated by the dotted lines x in Fig. 4. Fig. 4 is a longitudinal vertical sectional View, illustrating my said invention; Fig. 5 is a front elevation of my improved boiler, and Fig. 6

` tions cinto chambers A.

is a horizontal section thereof on line y Fig. 4. n

Having reference first to Fig. 1, A are headers designed to connect the tubes of the boiler, as hereinafter explained, and rectangular in p their oross-sectio11,with flat sides, and intended "35 to be placed on end-that is to say, vertical,-

to constitute the ends ofthe boiler. They are intended to be made of cast-iron or cast-steel, and each is divided horizontally by the parti- Each of these headers is provided at its inner side-with a pair of openings communicating With each of the chambers A', said openings being of such size and shape as to receive the adjacent inserted ends of the tubes B, which are preferably secured therein by being expanded into the said openings. The outer side of each of said headers is provided either with hand-holes arranged one opposite each of the openings B', or, in lieu thereof, the said headers may be originally formed with said outer side opened, and when put into use and operation have said sides closed by large plates B, each corresponding to the size and contour of the chamber A over or upon which it is placed, the said plates being held in position by suitable bolts, d. The

tubes B are arrangedin series, zigzagged vertically, as represented in Fi g. 4, in such manner that the water from the lowermost of the chambers A at thefront of the boiler may pass back and forth through the several chambers of the headers at the opposite endof the boiler until it reaches the uppermost `'of said headers, and passes thence into a steam-discharging chamber, C, placed at the top of said headers at the rear of the boiler, the said steam-discharging chamber communicating by a passage, C, with the steam-drum D, which latter has adjacent to the passage C a vertical partition, c, which extends up from the bottom ofthe drum to or above the middle thereof, the object being to `prevent the downward flow of the water from the rear of the said drum, if in any case the normal circulation of the Water through the boiler should be checked or reversed.-

The front of the steam-drum D communicates with the lowermost 0f the chambers A ofthe headers A by means of a chamber, E, in

ldirectcommunication with said end of said drum and tubes F, which communicate With a base-chamber, G, with Which the lowermost ends ofthe tubes communicate, as shown at c in Fig. 4. The tubes F communicate With the base-chamber G at the ends of the latter-as,

lfor example, at the parts indicated at f in Fig.

5the said ends of the base-chamber being bolted direct tothe tubes F, so. as to be suspended thereby, the said tubes F being extended farther down, resting upon suitable foundations, and tle other lower mud-drums for the boiler.

The iire-boX H may be arranged in any suit able or usual relation to the tubes of the boiler, and the latter may be provided at its sides With the usual brick-Work, I.

In` the operation of theboiler the Water from the lowermost of the tubes circulates from one to another of each of the vertical zigzagged series through the headers of such series, thence through the chamber C into the drum D, and, after traversing the latter, into the base-champarts constituting IOO ber G, and thence again into the lowermost of -the tubes, the steam being readily disengaged from the Water, as the latter passes up the chamber G behind the partition c into the drum. As represented in Fig. 1, and hereinbefore set forth, the headers are shown and described in their simpler form.

Further features of my said invention comprise additional construction and operation of the said headers in their relation to the tubes.

Having reference now to Fig. 2, in connection with Figs. 4, 5, and 6, the headers are made double-that is to say, are not only horizontally divided into the chambers A' ,but are divided by vertical partitions m, so that each header comprises two parallel vertical series of chambers, A', formed in one and the same casting. In this case one of the narrow headers hereinbefore described is employed at each end of the boiler and at opposite sides thereof,

las illustrated in plan view Fig. 6, so that while any two adjacent tubes in the same inclined plane shall at one end enter one and the same header, at their opposite ends they shall enter separate headers, the said tubes of each horizontal plane therefore, taken in connection with their headers, forming zigzagged water-courses, as illustrated in said Fig. 6. When the vertical partitions of these last-mentioned headers extend from top to bottom of the chambers A', the operation of the boiler will be substantially the same as that when the ends of the said boilers are made up of the narrow headers shown in Fig. 1, and hereinbefore fully described; but by forming openings inthe said vertical partitions at or near the upper endsof each of the chambers A', a lateral circulation of the water from-one of the vertical series of tubes to the other may be suffered to take place, to this extent modifying in some degree the circulation ofthe water.

Having reference to Fig. 3, taken in connection with Figs. 4, 5, and 6, the vertical partition m is replaced by two internal parallel walls, n, having spaces r between them, and with the opening p in both of them at or near the top of the chamber A', and with, furthermore, openings at the bottom through the said walls, and also an opening through the horizontal partitions a coincident with the said walls, as represented at r', this construction and arrangement facilitating the disengagement of steam from the upper part of the chambers A'-in other words, to prevent the locking of superheated steam inthe cavities above the. ends of the tubes B.

It will be observed that the arrangement of the headers and the holes and partitions therein leaves the tubes in straight lines, whether viewed horizontally or vertically. The horizontal arrangement leaves a clear horizontal space between any two series of tubes, which admits of the passage of cleaning devices between said tubes, and also of the use of the tiles T shown in Fig. 4.

What I claim 'as my invention is- 1. The compound vertical headers horizontally divided into chambers, as set forth, and

constructed with internal vertical walls, in combination with the tubes B, arranged to form zigzag series vertically and horizontally, leavingY a clear horizontal passage between each series, as described, said headers being placed side by side to forni the ends of the boiler, all substantially as and for the purpose herein set forth.

2. The compound vertical headers horizontally divided into chambers and provided with internal vertical parallel walls, n, having a space, r, between them, and openings p in said walls at or near the top of each chamber, in combination with the tubes B, arranged to form zigzag series vertically and horizontally, substantially as and for the purpose herein set forth.

3. The combination of the narrow vertical compound headers, the compound headers internally divided into series of parallel vertical compartments, and the tubes B, arranged in zigzag series vertically and horizontally, all substantially as-and for the purpose herein set forth.

4. rlhe combination of the narrow vertical compound headers, the compound headers internally divided by parallel vertical walls n, having space r between them, and provided with openings p, and the tubes B, arranged in zigzag series vertically and horizontally, all substantially as and for the purpose herein set forth. y

5. The combination of compound headers divided into chambers by horizontal partitions, and placed side by side to form the ends of the boiler, the tubes B,arranged in vertical zigzag series, the steam-discharging chamber C, formed independently of the vertical headers and receiving one series of tubes, and the drum D, all substantially as and for the purpose herein set forth.

6. The combination of compound headers divided into chambers by horizontal partitions, and placed side by side to form the ends of the boiler, the tubes B, arranged in vertical zigzag series, the steam-discharging chamber C, formed independently of the vertical headers and receiving one series of tubes, the drum D, and the return-pipes, all substantially as and for the purpose herein set forth.

7. rIhe combination of compound headers divided into chambers by horizontal partitions, and placed side by side to form the ends of the'boiler, the tubes B, arranged in vertical zigzag series, the steam-discharging chamber C, formed independently of the vertical headers and receivingone series of tubes, the drum D, the return-pipes F, and partition placed in said drum adjacent to the steam-discharging chamber, all substantially as and for the purpose herein set forth.
