I, AUGUSTE DAUSSIN Engineer in care of Messrs. Bede & Co. of 29 Rue Philippe-
le-Bon, Brussels, Belgium, do hereby declare the nature of my invention, to be as
follows:
--
This invention relates to means and method of automatically supplying boilers and
other receptacles with water or other fluid so as to retain a constant level in the said
receptacles.
The apparatus necessary for the purpose consists of a suction and force pump, and
certain mechanism hereinafter described by means of which the operation of the said
pump may be neutralized or suspended.
In the boiler or receptacle to be supplied is arranged a float, or the latter may be
arranged in a second receptacle communicating with the first in such a manner that
the level of water in the said special receptacle always corresponds to that of the
boiler or receptacle to be supplied. The float is suitably guided in the receptacle and
carries a projecting bolt, which ascends or descends with the float and is adapted,
when the float is raised to a certain height above the normal level, to arrive in front
of a lever and impede the motion of the same. This lever is so connected with the
inspiration valve of the pump which supplies the said boiler that the said valve is
periodically raised from its seat in correspondence with the motion of the lever, which
is adapted to take place at intervals. The lever may be raised by a cam or tumbler
arranged on or operated from the shaft which actuates the above mentioned pump, or
from any other gear.
The lever, or an arm of the same, is adapted to stand in front of the said bolt when
in its normal position and impede the motion of the latter in an upward direction,
until the said lever is moved by the cam, when it will move out of the range of said
bolt and allow therefore the float to adjust itself to the level of the water in the
receptacle. Should the latter be raised above the normal level, the float will at this
moment rise and carry with it the bolt causing the latter to arrive in the path of the
lever, so that the latter will be stopped on its course, and the inspiration valve of
D

page_text: the pump held from its seat, the consequence of which will be that the water sucked
in by the said pump, instead of being forced into the boiler, will return through the
unseated valve into the tank, and the action of the pump neutralized until the level of
the water in the boiler and therefore the float falls sufficiently to release the lever
which will then fall and allow the inspiration valve to resume its functions.
The cam or tumbler is so arranged as to operate the lever so as to lift it for a
moment at certain intervals.
In order to equalize the pressure in the float when the latter is made hollow, with
the pressure in the receptacle, a tube open at each end is arranged which projects
through the upper side of the float to which it is soldered or otherwise fixed and
terminates above at a suitable distance from the float, and below, near the lower part
of said float.

page_text: A New or Improved Apparatus for Retaining a Constant Level of
Water in Boilers and other Receptacles.
I, AUGUSTE DAUSSIN, Engineer, in care of Messieurs Bede & Co. of 29 Rue Philippe
le Bon, Brussels Belgium, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascertained
n and by the following statement :-
11
This invention relates to means and method of automatically supplying boilers or
other receptacles with water or other liquid, so as to retain a constant level of the
liquid in the receptacle.
The invention consists essentially in the combination of a device for feeding such
liquid, with a float rising and falling with the level of the liquid in the receptacle and
mechanism by which the excessive rise of the float arrests the function of the feed
device until by evaporation or other cause, the liquid in the receptacle falls sufficiently
to free the said mechanism from the restraint of the float and so enable the function of
the feed device to continue.
Referring to the accompanying drawing
Fig. 1 is a sectional elevation of a machine embodying the invention.
Fig. 2 is a portion of the same view with the mechanism in a position by which the
feed of the pump is neutralized.
Fig. 3 illustrates a modification.
A is a suction and force pump of convenient construction G being the suction valve
thereof B is a shaft driven continuously by power, and it may operate the plunger
of the pump by intervention of a crank or excentric in the known manner, or the
pump may be operated by an independent motor-M is a worm on said shaft B gearing
into the worm wheel L-J is an arm pivoted on shaft I and having the weight P
thereon-The said arm J is rocked at intervals against the action of the weight P, by
a cam or tumbler K acting upon a pin or roll on said arm, or by means of a chain or
cord S fixed upon the worm wheel L-The shaft I is passed through a stuffing box
within a closed chamber T where it is provided with a hook H. Before the nose of
said hook and in a direction across the direction given to said hook, is adapted to pass
a pin or block O connected firmly with the float C supported by the liquid in the
boiler or receptacle, or in the upper part of the chamber T the latter being then
connected to the boiler by pipes D and E with the lower and upper portions of said
boiler or receptacle respectively. The level of the liquid in T is therefore the same as
that in the boiler and the float C supported by the liquid rises and falls with the level
of said liquid-As the latter rises above the constant level to be maintained, the pin or
block O or its equivalent is brought before the nose of the hook H during the next
lifting of the arm J and is prevented from returning by said pin or block. After the
passage of the tumbler K or the termination of the tension on the cord S, the arm J
is held upward against the gravity of the weight P so long as the pin or block O or

page_text: its equivalent is before the nose of the hook H. Attached to the arm J is the rod F
having the foot extending under the valve G. When the arm J is raised as before
stated, the foot F¹, rising, lifts the valve G from its seat and holds the same in this
position, during the time that the arm F is held suspended. The water or other liquid
drawn into the cylinder of the pump is thus returned again into the reservoir through
the open valve and is not pumped into the boiler or receptacle-If the float Cis
formed of thin walls, the pressure in the space within the float is equalized with that
prevailing in the receptacle, by means of the pipe open above and below and
extending from near the bottom of the interior space in the float through the upper
wall thereof, in which it is soldered or otherwise fixed. In the modification shown in
Fig. 3, the tube t suitably extended above the float, may perform also the functions
of the pin or block O.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is ;—
For retaining a substantially constant level of water or liquid in boilers and other
receptacles
1) The combination of a float in said receptacle, or in a receptacle connected
therewith as described, a pin or equivalent adapted to rise and fall with said float, a
mechanism having an intermittent or other movement communicated thereto, said
movement adapted to be arrested by said pin or equivalent during excessive rise of
the float and a pump for supplying liquid to said receptacle, the function of said
pump being partly or wholly suspended or neutralized by and during the arresting of
said mechanism.
2) The apparatus substantially as herein described and illustrated embodying the
combination inentioned in claim Ï.
