STEAM-BOILER.

SPECIFICATION forming' part 0f Letters Patent N 0. 678,530, dated. July 16, 1901.

Application filed November 12, 1900. Serial No. 36,172. (No model.)

plication for Letters Patent, Serial No. 26,701,

filed August 13, 1900, and in said drawings- Figure 1 is a vertical transverse section, and Fig. 2 is a horizontal transverse section on line X X in Fig. 1.

In said prior application the construction of the boiler is such as to make it particularly desirable for furnishing the propelling power for locomobiles.

As set forth in the application referred to, the essential elements of the boiler are two upright shells, superposed one upon the other and constituting, respectively, the steamchamber and water-chamber, and a flue-sheet or diaphragm secured to said shells at their junction. In that case the shells'are hanged outward at their junction and the hue-sheet or diaphragm is seated with its margin between said ilanges and riveted thereto.

The present invention` resides in an improved manner of uniting said elements, the object being to increase the stiness and y strength of the boiler and also to lessen the the junction of said parts, as clearly seen in- Fig. 1. By flanging the two shells outward, as stated, a projection or ledge is produced on the exterior of the boiler, which projecthat owing to the peculiar construction of certain vehicle-frames said projection or ledge is not useful for the purpose and, in fact, is objectionable. Therefore another object of the present invention is to dispense with said projection and unite the two shells and iuesheet or diaphragm in such a manner as to produce a more rigid and stronger const-rnc'- tion and at the same time improve the appearance of the boiler.

Referring tothe annexed drawings, A represents the lower shell, A the upper shell, B the diaphragm,which constitutes a Hue-sheet, and a a are the usual flues or tubes, which are disposed vertically.

The shell A is superposed upon the lower shell A and constitutes the steam-chamber, the lowervshell constituting the water-chamber. Said shells arejoined telescopic and are rmly secured together by means of rivets b b.

The flue-sheet or diaphragm B is preferably formed integral with the top of the lower shell and Vserves to guard against foaming of the boiler and to prevent the water from entering into the steam-space. However, it will be seen that said flue-sheet may be formed of a separate plate and riveted to the shell in any suitable manner. Said flue-sheet or diaphragm B is provided with a plurality of small perforations cc, which allow the steam to enter into the chamber A.

The base of the lower shell A is formed with an outwardly projecting perforated flange d, to which is secured a iluesheet eby means of rivets f f.

The top of the upper shell A is provided with a flue-sheet g, similar to the flue-sheet e, and said flue-sheets coincide with the in term ediate flue-sheet or diaphragm B.

The iues or tubes d a extend through the three flue-sheets and are firmly secured at their ends to the top and bottom flue-sheets.

h representsv the usual steam-pipe, which preferably extends from the center of the flue-sheet g, and t' is the usual water-pipe, which communicates with the water-chamber A, preferably through the center of the iuesheet e.

C denotes a suitable case, which contains IOO the usual gasolene orother burner. (Not necessary to be shown.) Said case may be attached to the boiler in any suitable manner. In this case I have shown an angle-iron n, secured to the shell A by means of rivets b' b and detachably secured to allange c' formed at the top of the case by means of bolts d d'.

The products of combustion from the burner pass through the tubes a a and effectually heat the water in the chamber A, and the generated steam passes through the diaphragm B in a dry state to the steam-chambel ry.

Vhat I claim is- 1. A steam boiler composed of upright shells superposed one upon the other and united by telescopic joint, the bottoni and top of the boiler consisting of flue-sheets, a coinciding Hue-sheet extending across the interior of the boiler at the Water-level thereof and provided with steam-passages, and lines extending through said three uesheets and fastened to the bottom and top Hue-sheets as set forth.

2. A steam-boiler composed of an upright Water-chamber having its top and bottom plates perforated, said top plate being provided with steam-passages, a steam-chamber joined telescopic t0 the exterior of the upper portion of the water-chamber and having its 3o top plate perforated, and flues extending through the perforations of said three plates as set forth.

3. A steam boiler composed of upright shells superposed one upon the other and joined telescopic, a Hue sheet extending across the bottom of the lower shell, a coinciding fine-sheet extending across the top of the upper shell, and a similar [lue-sheet extending across the two shells at the junction thereof, and provided with steam-passages, and fiues extending through said three flue-sheets as set forth.

4. A steam -boiler composed of upright shells su perposed one upon the other, the lower shell extending near the water-line of the boiler and flanged at its base and formed at its top with a flue-sheet provided with steam-passages, a flue-sheet fastened to the flanged base of said shell, the upper shell joined telescopic to the lower shell and formed with a line-sheet at its top, and tlues extending through said three line-sheets as set forth and shown.
