page_text: We, HENRY BARROWS BAKER, Machinist, and GEORGE BOSTON BLAZER, Black-
smith, both residing at Nelsonville, in the County of Athens and State of Ohio, in
the United States of America, do hereby declare the nature of this invention to
be as follows:-
This invention relates to steam boiler cleaners. The steam boiler is traversed
from end to end and near the bottom by a horizontal pipe which projects beyond
both heads of the boiler except in cases when the device is put into portable boilers
or boilers having an iron fire-box then the horizontal pipe will only extend from
end to end and through the ends of the fire-box.
Through the beads or ends of the boiler or fire-box as the case may be, pass
thimbles, threaded both on the inside and outside which thimbles screw onto the.
horizontal pipe above mentioned, and for the purpose of making tight joints and of
holding the said horizontal pipe firmly in place, nuts are applied on the ends of
the thimbles.
Small curved jet pipes are screwed into the underside of the horizontal pipe and
said pipes curve in the direction of the blow-off pipe at the back end of the boiler
or fire-box and their lower and free ends extend to quite near the bottom of the
boiler or fire-box said lower ends being reduced in size in proportion to the amount
of steam and water that is required to pass through them and the said ends are set
so as to throw the water and steam over the entire surface of the bottom of the
boiler.
The object of the short curved pipes is to permit the water and steam that is
forced into the horizontal pipe to pass through them and agitate the water in the
boiler and create a current along the bottom of the boiler and thereby move all
dirt, sediment and accumulating scales in the direction of and up to the blow-off
pipe at the back end of the boiler or fire-box where the saine can be blown out.
The blow-off pipe is provided with a stop-cock or valve. A short nipple is
screwed into the projecting end of the thimble to receive an elbow the purpose of
which is to set the outside pipes and valves cross-ways or at right angles with the
boiler to have them out of the way.
A three-way pipe: is screwed into the outer end of a short pipe which screws into
a stop-valve or cock which is used for shutting off the water and steam in boiler in
order to drain the pipes in time of cold weather.

page_text: A cap-nut is screwed onto the outer end of the three-way pipe and has a hole
and thread cut in same to receive a conductor pipe one end of which has a thread
cut on it and same screwed through the cap-nut. The other end of this conductor
pipe passes through the three-way and extends into the short pipe before mentioned.
The purpose of this conductor pipe is to convey the matter through the three-way
and past where the steam enters the three-way from the top of the boiler.
The outer end of the conductor is provided with a check valve. A pipe
connects the force-pump or inspirator with the conductor pipe and its check valve.
Short pipes connected together enter the boiler at top and extend to the three-
way, the purpose of which is to convey steam into the three-way, which steam
passes through the latter around the outside of the conductor pipe.
The horizontal pipe which traverses the boiler is provided with a stop-cock to
blow out sand and dirt and to let the water escape from said pipe and permit the
same to fill with steam prior to putting in water from feed-pump.

page_text: We, HENRY BARROWS BAKER, Machinist, and GEORGE BOSTON BLAZER, Black-
smith, both residing at Nelsonville, in the County of Athens and State of Ohio, in
the United States of America, do hereby declare the nature of this invention and
in what manner the same is to be performed; to be particularly described and
'ascertained'in and by the following statement :—
Figure, 1, of the drawings is a representation of a vertical section.
Figure, 2, is a front elevation, partly in section.
Figure, 3, is a sectional view of a modification.
This invention relates to steam boiler cleaners; and it consists in the con-
struction and novel combination of parts, as will be hereinafter fully described,
and particularly pointed out in the claims.
Referring by letter to the accompanying drawings,
A, designates the steam-boiler, and the dotted line, x-x, designates the top
water-line in the boiler. A¹, designates the back end or head of the boiler, and,
A, the front end or head of the same.
B, designates a horizontal pipe that traverses the boiler from end to end near
the bottom of the same, and projects beyond both heads of the boiler, except in
cases where the device is put into portable boilers, or boilers having an iron fire-
box; then the horizontal pipe, B, extends from end to end of the boiler and through
the fire box. C, C, are thimbles having threads cut both on the inside and outside.
Said thimbles pass through the heads or ends of the boiler or fire-box, as the case
may be, and screw onto the pipe, B. Nuts, B¹, B³, are screwed onto the outside
of said thimbles and up against packing, for the purpose of making the joints tight
and of holding the pipe, B, firmly in its place. k, k, k, k, etc. designate small curved
jet-pipes, which are screwed into the under side of the pipe, B, and said pipos, k, etc.
curve in the direction of the blow off pipe, D, at the back end of the boiler or fire-
box, and their lower or free ends extend to quite near the bottom of the boiler or
fire box, and their lower ends are reduced in size in proportion to the amount of
steam and water that is required to pass through them, and their lower ends are
Bet so as to throw the water and steam over the entire surface of the bottom of the
boiler. The object of these short curved. pipes, kc, etc., is to permit the water and
steam that are forced into the pipe, B, to pass through them and agitate the water
in the boiler and create a current along the bottom of the boiler, and thereby move
all sediment, dirt, and accumulating scales in the direction of and up to the blow-
off pipe in the back end of the boiler or fire-box, as the case may be, where the
same can be blown out through the blow-off pipe, D, and by opening the blow-off
occasionally and letting it blow a little at a time the boiler can be kept clean all
the time. The blow-off pipe, D, is provided with a stop-cock or valve, D¹, which
may be opened at pleasure for this purpose.
E designates a short nipple which is screwed into the projecting end of the
thimble, C, to receive the elbow, J, figure, 2, the purpose of which is to set the
outside pipes, valves, &c., crosswise, or at right angles with the boiler, to have
them out of the way. n¹, and nå, designate stop-cocks or valves, the purpose of
which is to shut off the water and steam in the boiler, in order to drain the pipes
in time of cold weather,

page_text: m, designates a short piece of pipe, one end of which is screwed into the stop
valve, n¹.
F, designates a three-way or T, which is screwed onto the outer end of the
pipe, m. G, designates a cap nut, which is screwed onto the outer end of the three-
way or T.
The said cap-nut has a hole through the same and a thread cut therein
to receive the conductor pipe. S, designates the conductor pipe, one end of which
has a thread cut on it, and this end is screwed through the cap-nut, G. The other
end of said conductor-pipe passes through the three-way and extends into the short
pipe, m. The purpose of the conductor pipe, S, is to convey water through the
three-way pipe and past where the steam enters the three-way from the top of the
boiler. The outer end of the conductor-pipe, S, is provided with a check-valve, P,
to prevent the water and steam from flowing back from the boiler to the pump or
inspirator.
R, designates a pipe to connect the force-pump or inspirator with the check
valve, P, and the conductor-pipe, S.,
:
H, H¹, H³, H³, designate short pieces of pipe, which are connected together by
suitable joints provided for that purpose.
This sectional pipe enters the boiler at the top of the same, near the front
end, at, 4, and extends to the three-way. The object of this pipe is to convey the
steam into the three-way. The steam passes through the three-way, around the
outside of the conductor-pipe, S, a small space, S³, being provided for its passage.
The steam from the top of the boiler and the water from the force pump or inspirator
come together at the end of the conductor pipe, S, in the short pipe, m, and pass
through the cock or valve, n¹, and into the horizontal pipe, B, and through the jet
pipes, k, into the water near the bottom of the boiler, agitating the water, &c., as
before described. At the rear end, and outside of the boiler, the pipe, B, is provided
with a stop-cock or valve, V, the object of which is to blow out sand & dirt that
collect in the back end of the pipe, B, and to let the water escape from the pipe, B,
and to permit the same to fill with steam prior to putting on the water from the
feed-pump or inspirator.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1. The combination, with the steam boiler having the blow off pipe, D, and the
short pipe, m, of the horizontal pipe, B, with the curved pipes, kc, the sectional
pipe, H, the three-way pipe, F, cap-nut, G, conductor pipe, S, check-valve, P, and
the pipe connecting with the inspirator, substantially as specified.
2. The combination, with the boiler and the horizontal pipe, B, with downwardly
curved jet-pipes, k, of the sectional pipe, H, the three-way pipe, F, and the
conductor-pipe, S, the short pipe, m, and the stop-cocks or valves, n¹, n²,
substantially as specified.
3. The combination, with the boiler having the blow-off pipe, D, with cock or
valve, D¹, and the horizontal pipe, B, with curved pipes, k, and stop-cock or valve, V,
of the three-way pipe, F, the sectional pipe, H, connecting the boiler with the three-
way pipe, the conductor-pipe, S, the check-valve, and the supply pipe, substantially
as specified.
