UNITED STATES PATENT OFFICE. 1
WILLIAM KENT, O15 JERSEY CITY, NEW JERSEY.
BOILER-CLEANER.
SPECIFICATION forming part of Letters Patent No. 367,915, dated August 9, 1887.
Application filed February 10, 1887. Serial No. 227,238. (No model.)
To all whom it mag concern:
Be it known that 1, WILLIAM KENT, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Boiler-Oleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention; such as will enable others skilled in the art to which it appertains to make and use thesame.
My invention relates to'certain new and use ful improvements in boiler-cleaners, but has especial reference to that class of boilers in which there is a positive circulation of water, whethersuch circulation is obtained by a pump or other device outside of the boiler, or by'the construction of the boiler itself, as in the water-tube boilerherein shown, in which the circulation is always from front to rear in the water-drum, from rear to front in the inclined watentubes, and downward in the downtake.
The object of my invention is to free the water in the boiler and tubes from all impurities; and with this end in view my invention consists in certain details of construction and combination of elements, hereinafter fully make and use the same, I will "proceed to describe its construction and operation in detail, referring by letter to the accompanying drawing, forming a part of this specification, which shows a side elevation, partly in section, of my improvement. I
A is the water and steam drum, B the in clined water tubes, and O G the downtake and uptake, respectively. A pipe, D, with a flaring mouth, E, opposed to the direction of the current in the boiler, leads out of the latter into an auxiliary tank, F. From the top of this tank a pipe, G, leads into the downtake, for the purpose presently explained, said pipe having an outlet in the same direction as the current in the downtake.
1 The tank F may be a settling-tank only, in
which case the water entering by the pipe D V rises very slowly in tank, the suspended impurities settling at the bottom thereof, whence they are blown off through the pipe H; or there'may be a filtering apparatus inside the tank, as seen at J,.between the outlet of the pipe D and the inlet of the pipe G, through which all the water must pass before entering the pipe G.
As scum may occasionally rise to the top of the tank, a blow-off, K, is provided to remove it. This blow-off is also serviceable when it becomes necessary for the air to escape from the top of the tank.
WVhen circulation has become established throughout the boiler and tubes, the current in the downtake will induce a current from the tank through the tube G. The mouth E of the pipe D extends across a great portion of the water-body, and therefore, when the water flows from the tank through the pipe G, the water in the drum A will flow through the'pipe D and be discharged at the bottom of the tank. Thus it will be seen that a circulation is established throughout the tank, and the impurities settle at the bottom of the tank and are blown off, when desirable, through the pipe H.
The filter J may be used, if desired, as an auxiliary purifier; but after circulation has become fully established the water will be effectually purified of the heavier kinds of sediment without the aid of the filter. The pipe G, .outside the drum and tank, may pass through a flue or any other place where it will receive heat, and that part of the pipe D outside said drum and tank may be exposed to some cooling agent, whereby the current through the pipe G is accelerated, thereby assisting the circulation.
1 Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
In combination with a boiler and a settlingv WILLIAM KENT.
