PROVISIONAL SPECIFICATION.
An Apparatus for Automatically Starting and Stopping Electro-
motors Pumping Water into Storage Tanks without any Personal
Attendance whatever.
JOHN HARDING, The Mansion House, Stone, Staffordshire, Brewer, and JOHN
WILLIAM MILNER, Walton, near Stone, Staffordshire, Brewer's Engineer, do hereby
declare the nature of this invention to be as follows:-
The apparatus consists of an arrangement of levers, with 3 small wooden or cast
iron tanks numbered 1, 2, and 3, and 3 small wooden or copper floats numbered 1,
2, and 3, working in the said tanks. The whole arrangement is inserted into the
storage tank, which is to be filled with water. Number 1 float has a single action,
number 2 and number 3 have each 2 separate actions. The floats work in the
following order:
1st Action. Number 1 float by its' own gravity has the action and power to move
the lever of an ordinary electro-motor resistance starting switch into position for
starting, thereby closing circuit and starting electro-motor to pump water into
Number 2 tank.
2nd Action. Number 2 float has the action and power by the aid of water
pumped into number 2 tank by the first action, to move the lever of the said
starting switch into the position of "full on." When number 2 small tank is
full, the water overflows into the storage tank, which when full causes the 3rd
action.
3rd Action. Number 3 float has the action and power by the aid of water, to
open a single pole switch, thereby opening the circuit and stopping the electro-
motor.
4th Action. Number 2 float has the action and power by its own gravity to move
and bring the lever of the said starting switch to an off" position.
5th Action. Number 3 float has the action and power by its own gravity to
close the single pole switch, the cycle of operations being now complete.

page_text: declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
iment-
This apparatus consists of an arrangement of levers with 3 wooden or cast iron
tanks marked A, B, C, Fig. 1, and 3 wooden or copper floats marked D, E, F, in
said tanks. The tanks are all fixed together and the whole inserted and bolted
in the storage tank marked X which is to be filled with water.
Tank marked A, Fig. 1 consists of a box open at the top with the bottom open
to the storage tank X. Tank marked B consists of a box open at the top, with
close bottom; on one side of this tank is a small hole G open to the storage tank X
to allow the water in this tank to find the same level as the storage tank, when
the storage tank is getting empty; another hole marked H is connected to the
discharge from the pump of the electro motor. Tank marked C is the same
as A. Float marked F has a weight on top to make it heavier than float D. This
float has a single action. D and E floats have a double action. To each float is
attached a perpendicular rod marked J, L, M. Rod J has a tappet attached
marked Kadjustable by a thumb screw, the rods L, M, have each 2 tappets
marked N, N, and 0, 0, respectively also adjustable by thumb screws.
The rods of all the floats have guides marked P which keeps them perpen-
dicular.
J
The motor resistance starting switch marked R is placed over the tanks and has
a double-ended lever marked S.. At each end of the lever is a tappet eye through
which the rods J, L, work freely.
The method of working is as follows:-
The storage tank X being empty, float marked F, by gravity, brings the lever
of the resistance starting switch into position for starting, thereby starting the
electro motor. The tappet K on float rod J is. set in position to accomplish this.
The water is then pumped into tank B. through the hole H and fills this tank
quickly. The bottom tappet N is set in such a position that as the float D rises
it will bring the lever of the starting switch into position of "Full on." As soon
as tank B is full the water overflows into the storage tank X and causes float E
to rise. The bottom tappet O on the float rod M is set in such a position that
when the storage tank is full it opens a single pole switch which is placed in posi-
tion above tank C, thereby breaking the circuit and stopping the electro motor.
The top tappet N on float rod L is so placed that as the water in the storage tank
begins to fall, the float D), falling by gravitation has the power and action to bring
the lever S of the starting switch to an " off" position, and by the time the storage
tank is half empty this has been accomplished. The top tappet 0 on the
float rod M is set so that. by the time the storage tank is three parts empty, the
float E by gravitation closes the single pole switch, and the cycle of operations is
complete. Immediately before the storage tank is empty float F brings lever S
into position for first action.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed we declare that what we
claim is:-
The combined arrangement of the three tanks and the three floats with tappet
rods for automatically starting and stopping electro motors pumping into storage
tanks.
