SPECIFICATION forming part of Letters Patent 0. 579,615, dated March 30, 189'?. Anplioation iiled December 1'7, 1896. Serial No. 616,083. (No model.)

To a/ZZ whom it may concern:

Be it known that I, GEORGE HUsToN SToUT, a citizen of the United States, residing at Marceline, in the county of Linn and State of Missouri, have invented a new and useful Steam-Generator, of which the following is a specification.

The invention relates to improvements in steam-generators for feed-cookers and fruitevaporators.

The object of the present invention is to improve the construction of steam-gen erators and to provide a simple and ineXpensive one capable of easy manipulation and adapted to generate steam quickly at the expenditure of a minimum amount of fuel.

A further object of the invention is to provide a steam-generator which will dispense with a hre-box and grate and which will enable the boiler to be supplied with hot water and thereby avoid any loss of time or steam in relling the boiler. o

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is a perspective view of a steam-generator constructed in accordance with this invention. Fig. 2 is a central vertical sectional view.

Like numerals of reference designate corresponding parts in both iigures of the drawings.

l designates a boiler comprising an outer cylindrical shell or casing, an inner conical shell or lining 2, and a horizontal diaphragm or partition forming the top of the boiler proper and arranged below the upper edges of the outer shell and the inner lining to form an upper annular reservoir 4. The inn er conical lining is of the same diam eter at the base as the outer shell and its lower edges are riveted or otherwise secured to the same, and a tapering annular space is formed between the outer shell and the inner lining 2 to receive the water to be heated for the generation of steam. The steam-generator rests upon the ground and is placed over a wood fire which is built directly upon the ground, thereby dispensing with a tire-box and grate. A smoke-stack 5 is removably mounted on the upper portion 6 of the lining 2 and is provided with a suitable damper for controlling the draft, and the said upper portion 6 eX- tends above the upper edges of the outer shell, and the smoke-stack may be hinged or otherwise mounted on the upper portion 6 of the lining to permit it to be swung back or moved out of t-he way, so that the boiler may be supplied with fuel.

The reservoir or open space at the top of the steam-generator formed by the horizontal diaphragm or partition and the extensions of the lining and the shell is adapted to receive a supply of water, which is heated by the smoke and other products of combustion passing out of the smoke-stack, and when it is desired to supply the boiler with water an inlet 8 is opened to permit the hot water of the reservoir to iiow into the boiler. This prevents the boiler from becoming chilled or its operation checked, as would be the case formed by an opening, and a threaded iiange extends upward around the opening and is adapted to receive a stopper 9, consisting of threaded cap l0, adapted to screw on the flange of the inlet-opening.

The boiler is provided with upper and lower cocks or faucets ll and 12, forming a water-gage and a drip or drain cock. The lower cock or faucet enables the water in the boiler to be drawn off to afford a supply of hot water and to enable the steam-generator to loe emptied after it has been used to prevent any Water relnaining within it and rusting the parts.

A steam-discharge tube 13, which is substantially L-shaped, is located within the reservoir and extends through the horizontal diaphragm or partition 3 and the extension of the outer shell of the boiler. It is provided at its top with a threaded extension or flange 14, receiving a valve 15, arranged within the cap and provided with a stem eX- tending through the top of the same. The steam-pressure holds the valve normally closed; but should the steam exhaust and the pressure within the boiler becomeless than the atmospheric pressure on the exterior of the same the valve will open automatically and admit air to equalize the pressure were cold water poured into it. The inlet isa stem provided at its lower end with a IOO and prevent the boiler from collapsing or sucking in water or feed from a tank or trough in which feed is being cooked. The valve is automatic in its operation, both in opening and closing, and will prevent the escape of steam and permit the entrance of air. A hose 17 or other suitable disoharge'pipe is connected with the tube 13 and is designed to conduct steam into a fruit-evaporator and feed-cooker. The steam generated in the boiler has iree exit through the dischargetube and there is no liability of any explosion, so that the steanrgenerator can be readily operated by any one.

It will be Seen that the steam-generator is simple and comparatively inexpensive in Construction, that it is easily manipulated, and that it dispenses with a fire-box and grate, and is adapted to quickly generate steam with the expenditure of a minimum amount of fuel. It will also be apparent that there are no ilues or pipes which can fill up or rust out.

lVhat I Claim isi- In a steam-generator, the combination of an outer shell, an inner tapering lining extending u1 )ward from the bottom of the shell, a horizontal diaphragm connecting the shell and the lining between the ends thereof and dividing the space between the same into a lower boiler and an upper reservoir, said diaphragm being provided witha suitable inletopening and having a threaded .flange extending upward around the opening, a stem provided at its lower end with a cap adapted to sorew on the flange of the inletopening, an L-shaped discharge-pipe extending through the diaphragm and the upper portion of the shell and provided at its top with a threaded flange 14, alhreaded eap arranged on the said flange 1i and provided at its top with aperforation and a valve arranged within the eap and provided with a stem eX- tending through the perforation thereof, substantially as described.

ln testimony that I claim the foregoing as my own I have hereto affixed my signature in the. presence of two witnesses.

GEORGE HUSTON S"Oll"l`.
