Floats for Ball-cocks.
I, WALLACE HENRY BATE, of Belmont, in the County of Middlesex and
ommonwealth of Massachusetts, United States of America, Manufacturer, do
reby declare the nature of this invention and in what manner the same is
be performed, to be particularly described and ascertained in and by the
llowing statement:-.
My invention relates to floats for closing cocks in the supply pipes for tanks
nd similar vessels, and has for its object the production of a float that will close
he cock more firmly than any now in use, thus preventing leakage, and also one
hat will prevent the noise caused by the filling of.the tank.
I accomplish these objects by the device shown in the accompanying drawing,
n which
Figure 1 is a sectional view of a tank containing a float contructed in accordance
invention.
with the principles of my
Figure 2 is an isometrical view of the float.
Figure 3 is a vertical section through the float.
Figure 4 is a vertical section through a float constructed in a modified form upon
the principles of my invention.
Figure 5 is a view of one form of stop-cock that may be used in the supply pipe.
Like numerals refer to like parts in all the figures.
Referring to the drawing, i is a tank adapted to contain fluid; 2 is the pipe
supplying the fluid to said tank; 3 is the stop-cock in the pipe 2; 4 is a flexible
pipe, as for example, a piece of rubber hose connecting the outlet 12, of the stop-
cock 3, to the inlet 11, of the float 5; 6 is a small outlet in the upper part of the
float; 10 is a rod connecting the float with the stop-cock, and by which the valve
5 is turned; 13 is a chamber superimposed upon an air tight chamber 15, said
chamber 13 having an inlet nipple 11, an outlet 6, and a lip 14, partially closing
the top of the chamber.
The operation of my invention is as follows:
1
The fluid having been drawn from the tank, the float 5, falls to the bottom of the
30 tank, as shown by the dotted lines 8, Fig. 1, and in doing so, turns the valve
rod 16, of the stop-cock 3, thus admitting the fluid, which passes through the
flexible pipe 4, to the chamber 13, and fills the same till it reaches the edge of the
lip 14, as shown at Fig. 1, when it overflows into the tank.
The float is thus weighted by the fluid in the chamber 13, and remains at the
35 bottom of the tank, allowing the full supply of fluid to be admitted until there
is a sufficient depth of fluid in the tank to raise the float, together with the fluid
in the chamber.
As the float rises, the supply of fluid is shut off, leaving the chamber 13 filled
but this chamber, being above the level of the fluid in the tank, will discharg
40 its contents through the small opening 6, in the side near the bottom, thu
This causes the flo
increasing the buoyancy of the float, by removing the weight of the fluid there
from, and adding the fluid to that already in the tank.
to rise still farther, thus closing the valve more tightly than could otherwi
be done.

The fluid running over the side of the float and having but a short distan
to fall, makes but little, if any, noise; and the spattering, common
the fluid is admitted directly from the stop-cock, is entirely avoided.
I prefer to make the float as shown in Figs. 2 and 3, in which the chamber
tition 17. a little below the top of the walls of the float, but

page_text: desired, I can utilize the ball floats, as commonly inade, by surrounding one half of
the ball with a band, as shown in Fig. 4.
In order to give the float greater strength to support the weight of the fluid,
I carry the rod 10 completely through the float, as shown in Figs. 3 and 4,
securing both sides of the float thereto.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a tank or similar vessel, a float consisting of an air tight chamber and a
chamber adapted to receive and discharge fluid; and means for connecting said
last named chamber with a supply of fluid, substantially as shown, and for the
purpose specified.
2. In a tank or similar vessel, a float consisting of an air tight chamber and a
chamber adapted to receive and discharge-fluid; means for connecting said last
named chamber with a supply of fluid; and means for controlling the admission
and discharge of said fluid, substantially as shown and for the purpose specified.
3. The float 5, consisting of an air tight chamber 15, and the chamber 13,
provided with an inlet 11 and outlet 6, substantially as shown and described.
4. The float 5, consisting of an air tight chamber 15, and the chamber 13,
provided with a lip 14; inlet 11 and outlet 6, substantially as shown and
described.
5. The combination of the float 5, consisting of an air tight chamber 15, and a
chamber 13, adapted to receive and discharge fluid; the pipe 4; stop-cock 3 and
supply pipe 2, substantially as shown and for the purpose specified.
6. The combination of the tank 1; pipe 2; stop-cock 3; rod 10; pipe and
float 5, substantially as shown and for the purpose specified.
