MCKAY. amdgoilerl Patented Ma UNITED STATES PATENT OEEICE.
LOUIS MCKAY, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF TWOLTHIRDS OF HIS RIGHT TO FRANK B. MITCHELL AND `IILLIAM H. MITCHELL, OF
SAME PLACE.
STEAM-BOILER.
SPECIFICATION forming' part of Letters Patent No. 225,941, dated March 30, 1880. Application filed January 29, 1880.
To all whom 'it may concern Be it known that I, LOUIS MCKAY, of the city of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Circulating- Generators for Steam-Boilers, of which the folylowing is a specification.
The objects of my invention are to provide a cheap, simple, and eiiicient or reliable gen- Io erator to cause a positive circulation of the water in steam-boilers, so as to secure greater economy in fuel and increased capacity for generating steam, as hereinafter more fully -described and set forth; and it cqnsists in the construction, combination, and arrangement of an incline waterreservoir placed at one side of the boiler and connected by pipes with the water-space of the same, and also connected to a series of pipes formed in sections 2o and running at right angles to the said reservoir, and passing beneath the boiler and in the draft-space, and connected at their junction at opposite side of boiler with vertical pipes, which connect with a steam-drum placed above the boiler and connected therewith by pipes which enter the same, as hereinafter more fully explained by reference to the accompanying drawings.
Figure l represents a perspective view of a steamboiler with my invention applied thereto. Fig. 2 is a similar view of the reverse side of the same.
A represents a steam-boiler of usual construction, the brick-Work being broken away i 3 5 to show the connection ofthe several pipes which form my invention, wherein B represents a pipe connected with the water-space or interior of the boiler, near the bottom of the same, and extending on an incline or in a downward direction toward the reservoir C, placed on an incline, as shown in Fig. 2. I connect one of these pipes B at each end of the boiler A, so as to insure at all times the constant supply of water to the reservoir C,
which is provided with several series of horizontal pipes E, formed in sections of three, being united at their opposite ends, as shown in Fig. l. These sections, composed of the pipes E, extend at right angles to the boiler A, and
pass underneath the same, the first pipe in the front section being located near the lower portion of the draft-space D, and the next one somewhat higher, and so on, increasing gradually in height from front to rear, so as to cause the heat from the furnace to pass over and between the several pipes E in its ascent to the boiler A, whereby the water in said tubes or pipes E is quickly heated, so as to generate steam, which passes upward through the vertical pipes F, connected at their lower ends with the sections E and at their upper ends with the horizontal steam-drum G, located above the boiler A, and connected with the steam-space thereof by short pipes H, and having a pipe, L, connecting the lower portion of said steam-drum G with the said water-reservoir C, as shown in Fig. 2. This reservoir C is also provided with an outlet-pipe, N which is provided with a shut-oli valve, O, and connects with the usual blow-ottI pipe P, provided with the common shut-off valve, and connected with the mud-drum M, located beneath the boiler A, at the rear end of the grate, as heretofore.
R is a pipe connecting the steam-boiler A and mud-drum M.
Thus it will be seen that the water in the horizontal sections of pipes E will be converted into steam more quickly than the larger body of Water contained in the boiler A, and that this steam will pass upward and enter the boiler at the top, and that its space will be filled in the pipes E by a constant ilow of water from the reservoir C, which is fed from the water in the boiler just as fast as the water in the said pipes E is generated into steam, whereby a constant circulation of water is kept up and the heat utilized to the best advantage in generating steam.
It will be understood that this system of 9o pipes, forming the circulating-generator, is separate from and independent of the feed-water apparatus, as heretofore in general use, for keeping up a supply of water in a steam-boiler; and I am well aware that various devices have heretofore been employed for the purpose of hcatin g the feed-water, and that coils of pipes have been placed beneath the boiler, extending through the draft-space, Jfor the purpose steam-generating pipes E, beneath the boiler, 1o
of generating` steam; therefore I do not Claim l and which connect `with the steam-drum G,
such broadly7 as I am aware that it is not new. located above the boiler and connected with Having thus described my invention, what the steanrspaee thereof, substantially as and 5 I claim isfor the purposes set forth.
In combination with the boiler A, the reser- LOUIS MC-KAY. Voir G, placed alongside thereof and connected Witnesses: with the Water-space of the same by pipe B, SYLVENUS WALKER, and provided with the series of horizontal FRANK B. MITCHELL.
