Improvements in Apparatus for Controlling the Operation of Pumps.
I, HENRY HARRIS LAKE, of the Fum of Haseltine, Lake & Co, Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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; -
This invention relates to an improvement in pump governois, the object being
to produce a device which will automatically control the passage of steam to a
pump employed for the purpose of returning the water of condensation from steam
pipes to the boiler, in other words, the invention is designed for the purpose of
automatically opening a valve to allow of the passage of steam to a pump at a time
when it 18 desued to return the water of condensation to the boiler, and auto-
matically closing said valve when the chamber or receptacle holding the water of
condensation has been partially or completely emptied.
With these and other ends in view, the invention consists in certain novel
features of construction and arrangement of parts, as will be hereinafter fully
described.
The accompanying drawing shows our improved apparatus partly in section
and partly in elevation.
Referring to the said drawing, A represents a chamber or receptacle, of any
suitable size, into which at a, b, or o, as 18 most convenient, enters the water of
condensation from the steam pipes. To the top of the chamber A, is bolted or
otherwise secured the cover B, and at the bottom it is provided with the outlet
pipe C leading to the steam pump D. This pump, which is shown in outline may
be of any desued pattern or style, the only requirement being that it be capable
of receiving the water from the chamber A and forcing it to the boiler (not shown)
when steam is admitted to the cylinder E. To and over the top of the chamber A
is located a valve F to which leads a steam pipe (not shown) from the boiler, and
from which valve leads the steam pipe G for conveying live steam to the cylinder E
for operating the pump D.
Within the chamber A 18 located a hollow metal float H, pivotally secured to
one end of the lever I, which is fulci umed at d to the bracket e formed on or
secured to the outer side of the chamber A, the lever passing through the wall of
the chamber as shown
To the outer free end of the lever I is pivoted one end of the link J, the opposite
end of the latter being pivoted to the outer end of the lever K. The opposite end
of said level K is connected with the valve Fin such manner that when the outer
end of the former is lowered, the valve will be opened, and when the outer end of
said level K is raised the valve will be closed
From the foregoing it will be understood that when the water of condensation
in the chamber A reaches a certain height, it will raise or lift the float H. the

page_text: result being that the inner end of the lever I will also be raised, and the outer
end of the latter lowered. This motion is transmitted through the link J to the
lever K, the outer end of the latter being lowered and the opposite end raised,
thereby opening the valve F and permitting the flow of steam through the pipe G
to the cyhuder E, causing the pump to suck the water from the chamber A and
force it to the boiler or other point of discharge As the chamber is gradually
emptied, the float H descends, until finally through the medium of the levers, the
valve F 18 closed and the steam hom the boiler cut off, whereupon the pump ceases
to operate
It will therefore be seen, that the device is entirely automatic in its
operations, opening the valve as the water rises in the chamber and closing the
same after the latter has been partially emptied of its contents.
It will be understood by those skilled in the art, that many changes might be
made in the detail construction and arrangement of parts without departing from
the spirit and scope of my invention, as for instance, the lever may be differently
arranged, and instead of supporting the chamber A upon the pump as shown it
may be located at a distance therefrom
-
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim 18.-
1. The combination with the chamber A containing a float, of a pump connected
with said chamber and adapted to draw the water from said chambei and force
it to the boiler or other point of discharge, a steam supply pipe leading from the
boiler to the pump, a valve in said pipe, and levers connecting said valve and float
for automatically opening and closing said valve in the manner and for the purpose
described.
2 The combination with the chamber A containing a float, of a pump connected
with said chamber, a steam supply pipe G from the boiler to the pump, valve F,
and leveis I, J, K, the above parts being constructed and arranged in the manner
and for the purpose substantially as described.
