SPECIFICATION forming part of Letters Patent N o. 61 7,050, dated January 3, 1899. Application filed A t 27, 1898. Serial No. 689,676. (No model.)
To aZZ whom, it may concern:
Be it known that we, JOHN W. RICHARDS and WALLACE E. SHIPLEY, citizens of the United States, residing at Waverly, in the county of Tioga and State of New York, have invented a new and useful Improvement in Steam-Boilers, which improvement is fully set forth in the following specification and shown in the accompanying drawings.
Our invention is aduplex horizontal tubular or flue boiler designed more particularly as a rapid steamer, in which two separate but similar cylindrical boilers are associated,with their axes in a line and connected both as to their interior and exterior parts. The boilers are inclosed in abrick arch or sheet-metal covering in the usual manner, provided with the ordinary furnace, grate, ash-pit, and other appliances.
The invention is hereinafter fully described, and more particularly pointed out in the claims.
Referring to the drawings, Figure 1 is a front elevation of the device with parts broken away and other parts vertically sectioned through the axis of the boiler. Fig. 2 is a transverse section taken on the dotted line 2 2 in Fig. 1. Fig. 3 is an end elevation of parts of the device, seen as indicated by arrow 3 in Fig. 1, parts being broken away. Fig. 4 is a plan with parts broken out and other parts horizontally sectioned through the axis of the boiler. Fig. 5 is an elevation of the inner head of one section or part of the boiler, the arch and some other parts being vertically and transversely sectioned across the middle dotted line 5 5 in Fig. 1.
Referring to the drawings, A B are respectively the right and the left hand parts or sections of the boiler.
Dis the inclosing arch, which maybe of brick or sheet metal, E the furnace-space, and F a system of grates of any desirable construction.
G G are cross-walls, one under each part or section of the boiler, for inclosing the furnace-space.
H H are metal rings secured at the respective ends of the brick arch, the openings through said rings being covered or controlled by swinging doors I I. The sections A B of the boiler are equal and alike, short and cylindrical in form, and placed end toward end with space 0 between, their axes being in a line. They are provided, respectively, with horizontal flues a Z) below the middle or axis and a babove the axis. The sections are also joined along the middle horizontal line by a series of horizontal tie tubes or pipes c c, which aid to stay the sections together and also form passages for water between the sections. These boiler-sections are further connected and rigidly joined by plates or ties d d at the sides, Figs. 4 and 5, secured to the exterior of the sections. The series of connecting-tubes 0 cross the center or axis of the boiler and support a diaphragm 6, serving to divide the space 0 between the sections into an upper and a lower part. This diaphragm may be of brick, sheet metal, or other material,
as may be desired, and it serves to deflect the heat-currents from thefurnace to the right and the left, respectively, as indicated by arrows, instead of allowing these currents to pass straight up the passage 0 into the chimney K above the furnace. These heat-currents after passing through the lower flues a 19 enter chambers L L within the covers or doors I I at the opposite ends of the boiler and return through the fines a 1) into the space 0, and thence enter the chimney.
The connecting tubes 0 pass across the space 0, and they are alternated with a horizontal series of fines, as appears in Fig. 5, and opposite said tubes at either outer end of the boiler are placed screw-plugs f. These screw-plugs close orifices through which, when the boiler is constructed, is inserted an expander or other tool for expanding the ends of the tubes to secure them to the respective inner heads of the sections of the boiler. The sections are provided with the usual steam-pipes g and feed-water pipes h, which may be connected, respectively, above and below the boiler or not, as may be wished.
The two heads 2' 75, Fig. 1, of either section of the boiler are preferably flanged in the same direction, as shown, or, in other words, the head 79 projects into the boiler instead of outward like the head i. This turning of the head inward forms the smoke-space L at the outer end of the boiler under the door I, both outer ends of the boiler being alike in con= struction.
What we claim as our invention is 1. A steam-boiler comprising two coaxial shells provided respectively with internal longitudinal tubes opening through the heads of the shells, a horizontal series of tie-tubes intermediate of and establishing communication between the shells, and alternating with certain of the interior tubes, a diaphragm imposed upon the tie-tubes, a furnace below the space between the shells and a chimney above said space, substantially as specified.
2. A steam-boiler comprising two coaxial shells having concave outer heads and internal tubes opening through the shell-heads, tie-tubes arranged in horizontal series intermediate of the shells, and alternating with the interior tubes, a furnace belowthe space between the shells, a chimney above the said space and doors covering the concave heads, substantially as specified.
3. A steam-boiler comprising two shells pro= vided with outer concave heads and internal tubes opening through the shell-heads, tietubes extending between the shells and alternating with the internal tubes, a diaphragm imposed upon the tie-tubes, a furnace below the space intermediate of the shells, and a chimney above said space, rings retained against the edges of the outer shell-heads, an inclosing wall retained between the rings and doors closing the openings through the rings, substantially as specified.
In witness whereof we have hereunto set our hands, this 20th day of August, 1808, in the presence of two subscribing witnesses.
