/ WATER-TUBE STEAM-BOILER.
SPECIFICATION forming part of Letters Patent No. 591,445, dated 0otober l2, 1897.
Original application filed January 25, 1897, Serial No. 620,664. Divided and this application filed April 16, 1897.- Serial No. 632,436- (No model.) v
To ctZZ whom it may concern: 1
Be it known that I, EUSTACE ERNEST Wre- ZELL, engineer, of Billiter House,'Billite r Street, London, England, a subject of Her Majesty the Queen of Great Britain and Ireland, and a resident of Albion Cottage, High Road, Loughton, London, in the county of Essex, England, have invented a new and use ful Improvement in Water-Tube Steam-Boilers, of which the following is a specification.
The object of this improvement is to obviate the difficulties hitherto existing in boilers of this class with reference to drawing the tubes when these are arranged at an angle with thevertical and at the same'time'to increase the general efficiency of the structure as a steam-generator.
As compared with such boilers as commonly constructed my improved. boiler pos sesses the following advantages: The tubes can be withdrawn, plugged, or renewed with the greatest ease. It is most simple in construction. It possesses a very free circulation and great heating-surface, and in case of accident to or bursting of any tube the water would only run out of the section affected, the other sections remaining in working order, so that the boiler could be restored to duty with great rapidity.
My invention consists in certain novel combin'ations of parts hereinafter. set forth and claimed; and in order that the same may be the better understood I herewith proceed to Figs. 1 and 2 and omitted in Figs. 3 and 4.
Like letters refer to like parts in all the figures. V
In both-arrangements I locate with proper reference to one or more fire-chambers A, Fig. 1, groups (one or more) of water-tubes, each group having at top whatare herein termed end boxes Bin the form of square tubes parallel with each other and conveniently in contact with each other, within which the upper ends of the tubes 0 are expanded,
'thetop and bottom surfaces of said end boxes B being at an angle to the horizontal and .said top surfaces being provided with handholes D, indicated in the drawings by their stoppers, in line with the individual tubes.
Like end boxes E unite the tubes 0 into sections .at bottom and afford access by their hand-holes D to the lower ends of the tubes.
tween said connecting-tubes F. Branch pipes H, each providedwith a stop-cock I, extend endwise into the lower end boxes E from horizontal inlet-pipes J at bottom. A padlocked rod K, Fig. 3, extending through the gageholes in the squares of the stop-cocks (shown at I in Fig. 1) insures the opening of all the stop-cocks before firing the furnace, and a eirculating-pipe'L conveniently connects, if necessary, the bottom of the steam or water chests with the inlet-pipes J, as best shown in Fig. 3.
The tubes 0, connecting a pair of the end boxes B and E, constitute, with the latter, a distinct section, segregable as a whole, and the boiler is given the required capacity by employing a greater or less, number of such sections. The stop-cocks Ifacili tate locating the section in which a break has occurred and provide for stopping the How of water into and through such section from the remainder of the boiler.- The hand-holes D provide for withdrawing or plugging a damaged tube without disturbing the remainder of its section.
In the improved boiler shown in Figs. 1 and 2 the end boxes B and E have corrugated vertical sides, their corrugations fitting into each other, as shown in Fig. 2 at B B, whereby adjoining end boxes are interlocked with each other to a sufficientextent for mutual support. The end boxes E strike out from each side of the fire-chamber A and slope upward. The upper end boxes 13 are arranged at the same angle to the horizontal. The tubes 0 are straight and at right angles to the end boxes. The fire passes right and left in among the tubes 0 and upward between and around the connecting-tubes F, which lead from the corrugated end boxes B into the steam or water chests G, which in this boiler are arranged horizontally at the outer ends of said I upper end boxesB and at right angles thereto. Bathe-plates M, Fig. 1, preferably lead or direct the flames as they pass from the firechamber A between the tubes 0, and a steampipe N connects the pair of steam or Water chests G. Suitable side and end walls are represented at O and P, Figs. 1 and 2, and a vertical uptake at Q.
In the arrangement represented by side and plan views in Figs. 3 and 4 the end boxes B and E, in the form of square tubes, each have two sides facing downward and two sides facing upward, and the tubes 0 are suitably curved. These tubes are expanded within the upper end boxes 13 and lower end boxes E in the same manner as the straight tubes above described, and the end boxes are provided with hand-holes D, as aforesaid, so that the curved tubes C can be plugged or drawn individually through the upper end boxes B. The connecting-tubes F lead from the upper end boxes 13 into a single steam or water chest G. The branch tubes H, stop-cocks I, inlet-pipe J, padlocked rod K, and circulating-pipe L, Figs. 3 and 4, have already been described.
In making a continuous boiler I can place two groups, such as are formed by the corrugated end boxes B and E, straight tubes C, and connecting-tubes F, Figs. 1 and 2, with or without the baiile-plates M, on the respective sides of a single steam or water chest G, connecting the upper end boxes B at their highest ends by said tubes F direct to the steam or water chest on each side of the latter, and passing fire or heat in among the tubes 0 and between the connecting-tubes F to the uptake in any approved manner. A similar arrangement can also be made with the curved tubes shown in Figs. 3 and 4.
My boiler can also be made double-ended either by placing two sets, such as above described, back to back or by introducing a fire-brick partition in the center, so that firedoors can be fitted to each end.
All patentable combinations of parts hereinbefore described which are not hereinafter claimed are disclaimed in favor of the specification forming part of my application for United States Letters Patent filed January 25, 1897, Serial No. 620,654, of which my present application is in part a division.
My present improvement is intended to be confined to the means hereinbefore described for limiting the escape of water in case of accident and facilitating the withdrawal of the individual water-tubes.
Having thus described the said improvement, I claim as my invention and desire to patent under this specification 1. In a Water-tube steam-boiler, the combination substantially as hereinbefore specified of withdrawable water-tubes in a group or groups, made up of segregable sections, and having end boxes in the form of square tubes at the top and bottom of each section arranged with top and bottom surfaces at an angle to the horizontal, and provided with hand-holes in the tops of the upper end boxes and bottoms of the lower end boxes in line with the individual tubes, an inlet-pipe at the bottom of each group, branch pipes connecting said inlet-pipes with the lower end boxes, and means for stopping said branch pipes individually.
2. The combination, in a water-tube steamboiler, of a horizontal inlet-pipe at the bottom, end boxes at the bottom of each section, branch pipes extending from said inlet-pipe into the adjacent ends of said end boxes individually, and a stop-cock in each of said branch pipes, substantially as hereinbefore specified.
3. The combination, in a water-tube steamboiler, of a horizontal inlet-pipe at bottom, end boxes at the bottom of each section, branch pipes extending from said inlet-pipe into the adjacent ends of said end boxes individually, a stop-cock in each of said branch pipes having a gage-hole in its square, and a padlocked rod which occupies said gage-holes when all the stop-cocks are open, substantially as hereinbefore specified.
