Improvements in Mechanical Water Purifiers.
I, HERBERT BARBOUR WRIGHT, of 181 East Erie Street, Chicago Cook
County, Illinois, United States of America, Engineer, 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 :-
The object of this invention is to obtain an apparatus wherein and whereby
water may be purified before it is introduced into the boiler of a lo :o:motive, or
other steam generating apparatus, and thereby the formation of scale, largely, if
not wholly, prevented.
The manner in which I accomplish the object sought by me is hereinafter fully
described. Briefly stated; I obtain the results sought by placing adjacent to the
boiler a receptacle, admitting thereto hot water under pressure slightly greater
than the pressure carried in the boiler, (that is so that an automatic How of water
therefrom into the boiler will occur when the apparatus is being used, through a
connecting pipe); in connecting the water supply to such receptacle by a pipe.
extending into such receptacle from the injector ordinarily used for forcing water:
into the boiler; and by so connecting a pipe from the boiler to the cold water
supply pipe that the introduction of cold water into the receptacle, through the
cold water supply pipe, will also introduce a sufficient quantity of hot water from.
the boiler to raise the temperature of the entire contents of such receptacle so
high as to cause the precipitation of the substances desired to be gotten rid of
and contained in the water, while such water is in such receptacle.
In addition to the foregoing construction, I place a well at one end of the
receptacle so that the water extending through the receptacle will pass over the
mouth of the well, before being discharged from the well, and I place a blow-off
cock at the lower end of the well so that whatever substance is deposited or
precipitated in the well it may be cleaned therefrom.
so that the water
I also prefer to have a deflecting plate, placed in the receptacle
passing through the receptacle is forced to extend thereunder and a slight distance
into the well, thereby ensuring the deposit or precipitation in the well of the
substance or material taken from the water passing through the receptacle.
Further, I place on the receptacle a dome, in which will be collected such
substances as are separated from the water and are of less specific gravity than
such water, and a blow off cock from such dome.
.
In the drawing referred to as forming a part of this specification ;-
Fig. 1 is a side elevation of a locomotive boiler having an apparatus embodying
my invention connected thereto;
Fig. 2, an enlarged longitudinal central vertical section of the apparatus
embodying the invention;
Fig. 3, a cross section on line 3-3 of Fig. 1, viewed in the direction indicated
by the arrows.
A letter of reference applied to designate a given part is used to indicate such
part throughout the several figures of the drawing, wherever the same appears.
A is the locomotive boiler. B is the receptacle adjacent to the boiler A.
I prefer the receptacle B to be a cylinder constructed of sheet steel or sheet iron,
forined up and riveted together, in the ordinary manner, as by rivets b, b; and
.:

page_text: I prefer also, that the ends of cylinder B shall be dished in, so that the rivets b',,.
holding such ends in place may be riveted from the outside of the receptacle; such.
receptacle not necessarily being of large diameter, as compared with the diameter
of the boiler, the feed water whereof is to pass through it. C is an ordinary
injector for forcing feed water into a boiler. D is a feed pipe extending from
injector C to water injector E. E is a water injector opening into (and discharging)
receptacle B. F is a discharge pipe or nozzle of injector E and is placed on the
end of the pipe D, or so that such pipe D can be connected thereto. G is the
discharge opening of injector E. il is a pipe extending from boiler A into
injector E, and discharging into the chamber around the discharge nozzle F, so
that hot water extending from the boiler A through pipe H will be forced into the
receptacle B in the ordinary manner of working injectors. I is a discharge pipe
from receptacle B, extending therefrom into the boiler A. J is a well in
receptacle B, near the end thereof from which discharge pipe I, extends. K is a
blow-off cock from well J. L is a dome on receptacle B. M is a pipe extending
from dome L, and N is a blow-off cock in pipe M. O is a deflector plate iu
receptacle B.
The manner of operation of my mechanical purifier is as follows:-When
the injector C is opened the feed water from the supply is forced therethrough,
through pipe D, nozzle F in injector E, and into the receptacle B, through the
discharge G in injector E. At the same time hot water from boiler A is drawn
through pipe H and forced through discharge G into receptacle B, along with the
cold water. Such hot water in its passage through discharge E is intermingled
with the cold water discharged through nozzle F. The cross-sectional area of
receptacle B is considerably greater than the combined cross-sections of pipes G
and H, (as well as of discharge pipe 1), and the contents of such receptacle Bare
substantially at rest while passing through the receptacle; there being a slow
current through the receptacle toward the discharge end thereof, when the
injectors and E are forcing water into the receptacle B, through such receptacle
and into the boiler from the discharge end of the receptacle, through pipe I.
As such water extends through the receptacle B, the water being in a highly
heated condition the matter or substânce de-ired to be taken from the water will
be precipitated in the receptacle B, and where, as I at all times prefer, the well .J
and deflector plate O are used, such substances as are of greater specific gravity
than the liquid contained in the receptacle B will be deposited in such well J, from
which it can be withdrawn by opening the blow-eff cock K.
Where the dome L is used, substances of less specific gravity than the liquid
contents of the receptacle B will be collected in such dome and can be removed
therefrom by opening the blow-off cock N.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A receptacle for liquid, consisting of a horizontal cylinder, an injector
discharging into the receptacle at one end of the cylinder on the upper side
thereof, a pipe extending to the injector from an ordinary feed water injector, a
second pipe extending to the injector from the boiler whereby hot and cold water
are forced into the receptacle, a discharge pipe through the center of the head
of the discharge end of the receptacle extending therefrom back to the boiler,
a dome near the discharge end of the receptacle and a well in the receptacle
between the dome and the discharge end; substantially as described.
2. A receptacle for liquid consisting of a horizontal cylinder, an injector
discharging into the receptacle at one end of the cylinder on the upper side
thereof, a pipe extending to the injector from an ordinary feed water injector,
a second pipe extending to the injector from the boiler whereby hot and cold
water are forced into the receptacle, a discharge pipe through the center of the
head of the discharge end of the receptacle extending therefrom back to the

page_text: boiler, a dome near the discharge end of the receptacle, and a well in the receptacle
between the dome and the discharge end with a deflector plate extending from the
upper side of the cylinder adjacent to the dome into the well and near to the bottom
thereof; substantially as described.
