STEAM BOILER.
No. 23,470. Patented Ap 1w5, 1859.
UNITED STATES PATENT OFFICE.
EDMUND M. IVENS, OF NEWV ORLEANS, LOUISIANA.
IMPROVEMENT IN STEAM-BOILERS.
Specification forming part of Letters Patent No. 23,470, dated April 5, 1859.
To all whom it may concern.-
Be it known that I, EDMUND M. IVENS, of the city of New Orleans, in the State of Louisiana, have inveifited a new and useful Improvement in Portable Steam Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings through letters of reference marked thereon, forming part of this specification, in
which- Figure 1 represents an elevation of my improved boiler; Fig. 2, a cross-section on the line 0c 00 of Fig.1, and Fig. 3 a vertical longitudinal section on the line 0 0 of Fig. 2.
The same letters of reference indicate corresponding parts in the several figures.
My invention has reference to that class of boilershaving a series of flue-tubes passing horizontally through the cylinder and commonly known as horizontal tubular boilers, the objections to which are, first, in the great difficulty of freeing them from the sediment that naturally collects between the tubes and the consequent rapid destruction of the tubes owing to such deposit; secondly, in the difficulty and expense of repairing them, which, as a general thing, renders it cheaper to abandon such boilers when they begin to fail rather than to undertake to repair them; and it consists in substituting therefor the ordinary single or double flue cylinder and inserting within said flue or flues an annular or other water-drum connected at or near its highest point at one end with the body of the boiler and receiving its supply of water from the force-pump at or near its lowest point at the opposite end, thus having but one rigid connection with the boiler, which is made by a screwed tube or flange and which may easily be detached and the entire drum removed for repairs or renewal, the advantages of which are economy of first cost, increased durability, and facility for repairing.
To enable others to make and use my invention,l will describe its construction and operation, as follows:
I take a plain horizontal cylinder-boiler A, with a fire-box B at one end surrounded on all sides and at top with a water-space C, and
having a flue D of about half the diameter of the main cylinder A passing through it from the fire-box B to the smoke-stack E, this flue being arranged near the lower side and in the Water half of the cylinder. In this flue, extending from end to end,-is inserted a cylindrical water-drum of suitable diameter to leave sufficientflue-space around it to carry off the smoke from the furnace, or it may be made with an inner flue F also, the two cylinders being connected together at the ends by a ring't' between them, thus making an annular water space with a flue passing through the centerand around it within the main time D of the boiler. This water-drum is connected with the boiler by a tube G at the furnace end in such manner that it may be easily detached for repair, and is supported on a cast-iron bridge m in the rear end of the flue D, and is supplied with water direct from the force-pump of the engine through acheckvalve or at the rear end at or near the lowest point. Thus the cool waterinjected is made to' circulate this drum through the entire length of the flue and become thoroughly heated before it enters the steam-generating part of the boiler, while the forced circulation will prevent the deposit of sediment in the drum and carry it over, Wherait will be deposited in the water-space at the sides and back of the fire-box, to be blown out at the blow-off cock II.
The great advantage in this boiler is that Whenever the water-drum shall become defective from any cause it can be readily removed for repair or renewal by detaching the tube G, when, if necessary, the boiler maybe used without it by simply plugging the aperture where said tube was connected and attaching the feed-pump to the blow-ofi cock H or any other suitable place, all of which can readily be accomplished by any ordinary hand and the boiler made available (though somewhat curtailed 'in its capacity and effectiveness) during the time the drum is undergoing repair.
In other respects this boiler is fitted and furnished the same as any other horizontal boiler.
Havingfully described my invention, what I claim as new, and desire to secure by Letscribed my name this 23d day of October, A.
ters Patent, is D. 1858.
The arrangement of a cylindrical or annu- 1am water-drum (having a forced circulation) within the flue of an ordinary flue-boiler, in Witnesses: the manner and for the purposes set forth. WM. M. SMITH,
In testimony whereof I have hereunto sub- JOHNS. HOLLINGSHEAD.
EDMUND Ml IVENS.
