Letters Patent No. 108,394, dated October 18, 1870.

IMPROVEMENT IN STEAM GENERATORS AND HOT-WATER APPARATUS.

The Schedule referred to in these Letters Patent and making part of the same.

`is a full and exact description of the same,l reference Abeing had to the accompanying drawing and to the letters of reference marked thereon.

This invention consists in the peculiar construction of the boiler and furnace of an improved heating apparatus, and also in the arrangement of the tanks and connecting-pipes.

y The details ot' construction and manner ot' opera tion will be fully described hereinafter.

In the drawing- In sheetl is shown a perspective view of our improved apparatus complete.

In sheet 2, Figure 1, apartial perspective view is also shown, taken from a different point ot' view Figure 2 represents a central vertical section ofthe boiler; and

Figure 3, a centra-l longitudinal section ofthe same.

To enable others skilled in the art to make and use our invention, we willnow proceed to describe fully its construction and method of operation..

A represents the furnace, which contains the boiler B, as shown.

O represents the supply-tank for the boiler.

I) represents the main reservoir, from which`the supply of water is drawn; and

E represents the steam-chamber in which the steam is stored, and from which it is conveyed to any desired point.

@represents the pipe which connects the supplytank() with the boiler B, by means of which the necessary supply of water is kept up.

71 represent-s a pipe connecting the upper part of the supply-tank with the upper chamber ci' the boiler, by means of'which the pressure in both chambers is equalized.

c represents the pipe which connects the lower chamber of the boiler with the upper.

d represents the pipe connecting the upper Achamber of the boiler with reservoir E, by means of which the steam is conveyed from the former to the latter.

e represents the pipe connecting the 4main waterreservoir D with the supply-tank O, by means 0f which water is supplied as may be necessary.

f represents a pipe connecting the tank E with the pipe a., by means of which the contents of the 'former may be drawn oi', if desired.

Th'e boiler B is peculiar in its construction. It consists of two vessels or chambers, b b2, of the same shape and size, which are provided with diaphragms b3 b4, as shown, and arcunited at abut their centers, by means of a nipple, 115, as shown in g. 2, sheet 2. It will be observed that the upper end of this nipple is flush with the bot-tom of the upper chamber, but extends a short distance below the top ofthe lower chamber. By means of this arrangement any water'which may be condensed from the steam'in the upper chamber `is permitted to ow back into the lower chamber.

It will be observed that the sides of the boiler are inclined, and the sides of the furnace, in which it is inclosed, correspond with it in shape. The advantages of this construction will be perceived upon careful consideration. i

The boiler is brought into close contact with the fire, which, in tact, envelopes its lower part. Intense heat is thus quickly and easily obtained from a small amount of fuel.

The manner of operating our improved apparatus, when used for; the generation of steam, will now be described. f t

VVat'er is admitted into the lower section of the -boiler B from the tank C, by means of the pipe a,

until it is filled, the height of the water being determined by the wateigauge g in the usual manner. The fire may now be started, and, as the water is heated, the generated steam will be driven in the direction of the arrows, (iig. 3, sheet 2,) out of the chamber bl through the pipe c into chamber b2, when it becomes super-heated, and thence out through pipe d into reservoir E, from which it may be conveyed to any desired point.

rIhe pipe d is provided with an ordinary steam,- gauge, 'to indicate the pressure of the steam, and the tank E 'is supplied with a safety-valve of any proper construction.

Any water which may collect in tank E, from the condensing steam, may be drawn oli" by means of the ipe f. p When it is desired to replenish the supply-tank (l with water from-the tank D, the stop-cocks 7i, sheet 1, and h', sheet 2, iig. 1, are closed, by which means the connection between the supply-tank C and the boiler is cut ofi'. The blow-oli` cock i upon the tank is, then opened, and the steam allowed to pass olf. The valve j now beingcpened, the water from water-reservoir D will pass directly into the supv ply-tank by means ot' its own gravity, the pressure ot' steam from the boiler having .been cnt oii from the tank, by means of the valves described, and the steam having been allowed to escape ii'om the tank itself'.

, When oui-improved apparatus is used as a hotwater heater, th'e supply-tank O s not used.

The tank E is illed with water from tank I), by

Y means ofthe pipe e, which connects with the pipe a;

`or it may be drawn from the tank E by means of the pipe f, the tank E being replenished from the tank D.'

vlqlie special form and arrangement of our appara,- tus are especially adaptedfor a hot-water heater, inasmncl'l as a large supply of heat is' obtained from the consumption of a small amount of fuel.

The boilers are provided with the usual hand-holes and openings, for cleaning'purposes. We do not limit ourselves to the precise position of parts shown, nor tothe precise arrangement of pipes, but design, in practice, to makevsuch changes as may be necessary inthe varying circumstances ofthe case.

` Having thus fully described our invention,

What we claim as new, and desire to' secure by Letters Patent of the United States, is-

'1. TheboilerB, constructed specifically as described,

day of June, 1870. Y
