ARTHUR HERSGHMANN, OF NEW' YORK, N. Y.
SPEGIFICATION forming part of Letters Patent N 0. 740,361, dated September 29,1903.
Original application filed October 3, 1902, Serial No. 125,735. Divided and this application filed March 4, 1903. Serial No. 146,129. (No model.)
To all whom it may concern:
Be it known that I, ARTHUR Hnnsonnann, a subject of the Emperor of Austria-Hungary, residing in the borough of Manhattan, city, county, and State ofNew York,have invented certain newaud useful Improvementsin Draft Devices for Steam-Boiler Furnaces, of which the following is a specification, reference being had to the drawings accompanying and desirable.
It consists of the novel features and combinations hereinafter described, and more'panticularly pointed out in the claim.
Referring now'to the drawings, Figure 1 is. a vertical section of a boiler and furnace with which my invention is employed. Fig. 2 is a top plan View of the same.
1 designates the boiler-shell, having crownsheet 2. Extending up within the lower end of the boiler is a fire-box or furnace 3, having a top 4, between which and the crown-sheet 2 are the usual tubes 5 and a larger central fiue 6. By this arrangement of the fire-box a narrow space 7 is formed around the same, thus increasing the heating-surface of the boiler and making the generation of steam more rapid. On top of the boiler is a dome 8, into which open the fines 5 and 6, having a downwardly-extending stack 9 for the escape of the products of combustion. The steam-outlet of the boiler is the connection 10, having a suitable valve, to which is connected a superheated pipe 11, extendinginto the dome or superheating-chamber 8 and thence out again to the engine. In the superheating-chamber the pipe 1 1 may be coiled, as shown, or otherwise arranged to expose as large a surface as possible to the heat, so that the steam is superheated before it is utilized.
In order to increase the draft in the furnace or fire-box 3, the exhaust from the engine is discharged therein through the-exhaust-pipe 12, to which is connected the ring 13 in the fire-box, preferably conforming to the shape thereof, having openings, as 14,
through which the exhaust-steam escapes.
oughly heated before it is discharged in the ash-pit 17 under the grate 18. A valve 19,
.operated by a system of levers 20, controls the supply of air to the fire from the blower. In Fig. 2, 21 designates any suitable inlet for feed-water.
From the foregoing description it will be clear that the boiler by reason of its great heating-surface and the economical forceddraft devices will generate steam rapidly and yield a very high power in proportion to its size. It is therefore well adapted for automobile propulsion, as before stated. Of course the embodiment shown and described is only one of many forms which my invention may take, and I am not limited to that So precise form. In this application I make no claim to the boiler itself and the steam-superheating devices, but have claimed these in an application filed by me October 3, 1902,
Serial No. 125,735, of which the present application is a division.
What I claim is- The combination with av boiler and a furnace to heat the same, of a dome located on the boiler into which the products of com-- 0 bustion are directly discharged, a downwardly extending smoke stack connected with said dome, a blower operatively connected with the furnace, and a pipe for supplying air to the blower extending within the stack, as and for the purposes set forth.
