Improvements in and relating to Hydraulic Air-compressing
Apparatus.
I, AUGUSTE DEVIS, of Lodelinsart, in the Kingdom of Belgium, Builder, do
hereby declare the nature of this invention to be as follows:-
My invention relates to an hydraulic air-compressing apparatus comprising a
receptacle made of wrought iron, cast iron or other metal, in which is provided a
mechanism actuated by water. A three-way cock forming part of this mechanism
is placed in the interior at a short distance from the bottom of the receptacle. The
first way is designed for the admission of the water into the cock, the second way
serves for the admission of the water into the receptacle and the third way is
connected with an outlet pipe. In the receptacle are arranged two floats made of
massive wood, iron or other metal. One of these floats constitutes a reservoir of
zinc, copper or the like. When this float is in its upper position the water enters
the receptacle, raises a ball float which controls the plug of a cock fixed to the base
of the said float, and which on heing raised closes the said cock. As the water
rises it compresses the air between its surface and the upper cover of the receptacle
and finally enters the float after the utilization of the compressed air.
reservoir being weighted by the water causes two rocking levers to turn upon their
pivot. By their rocking movement these levers raise the second float and lower
the first float or reservoir, the cock of which is closed by the said ball float. As
the first float is lowered it opens the water outlet. At this moment the receptacle
is emptied and thus compels the ball float to descend. In the downward movement
of this float the latter opens the cock of the first float to discharge the water which
it contains at the same time as the water in the receptacle is let out. The float
being, thus lightened rises by reason of the weight of the second float which
redescends and in this movement again opens the water admission pipe connected
with the three-way cock and closes the water outlet. At this moment the water
enters the receptacle and compresses the air again.
The
It will be seen that the movement is purely automatic and continuous as long as
it is actuated by any water pressure.
When the pressure becomes too great for
the purposes for which the apparatus is designed it will be automatically regulated
by a device which comprises a box containing a cock or valve and connected with
a water admission pipe and outlet pipe joined to a pipe for the introduction of the
water into the receptacle. A lever adapted to turn upon a pivot and bearing a
weight regulates the pressure when air, water, steam or the like enters the said
box. It raises the valve retained by a rod which is under the control of the said
lever, which also bears by means of a second rod upon the before-mentioned valve
placed upon the box and communicating with the interior of the said box. This
valve is made of sheet copper or other metal or material by soldering or uniting
two round, oval, square or otherwise shaped parts upon each other. This com-
bination is such that the further the weight is moved towards the extremity of the
aforesaid lever the more pressure is exerted upon the valve, and the higher the
valve rod rises the more water passes easily into the box and the more pressure is
obtained. The contrary effect is obtained if the weight is moved forward towards
the said valve, for the resistance of the latter is diminished by enabling it to be
inflated. As this takes place the weight exerts a pressure upon the valve by the
rod which prevents the entrance of the water and thus regulates the pressure to as
many atmospheres as may be desired by the simple displacement of the weight. A
bell is provided at the upper part of the receptacle, forming an air purifier through

page_text: which the air enters the said receptacle, passing on its way through a pressure and
suction valve. The receptacle is further provided with a pipe for the supply of the
compressed air to the place where it is to be utilized, with pipes for introducing
the air into the receptacle, and with a pressure gauge.

Improvements in and relating to Hydraulic Air-compressing
Apparatus.
I, AUGUSTE DEVIS, of Lodelinsart, in the Kingdom of Belgium, Builder, 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 :-
My invention relates to an hydraulic air-compressing apparatus comprising a
receptacle made of wrought iron, cast iron or other metal, in which is provided a
mechanisin actuated by water.
In the accompanying drawing,
Figure 1 is a side elevation partly in section of an apparatus constructed
according to my invention and,
Figure 2 is a similar view showing the mechanism in a different position.
A indicates the receptacle for containing the mechanism.
A three-way cock forming part of this mechanism is placed in the interior at a
short distance from the bottom of the receptacle. The first way C is designed for
the admission of the water into the cock, the second way D serves for the admission
of the water into the receptacle A and the third way is connected with an outlet
pipe. In the receptacle are arranged two floats E and F one E of which is made
of wood or of iron or other metal and the other F of which constitutes a reservoir
of zinc, copper, or the like. When this float F is in its upper position as shown in
Figure 1 the water enters the receptacle, A raises a ball float G to the position
shown in Figure 2 which controls the plug of a cock H fixed to the base of the
said float F which on being raised closes the said cock H. As the water rises it
compresses the air between its surface and the upper cover of the receptacle A and
finally enters the float F after the utilization of the compressed air. The
reservoir F being weighted by the water causes two rocking levers ii J J, Figure II
to turn upon their pivots. By their rocking movement these levers raise the second
float E, Figure II and lower the first float or reservoir F as shown in Figure II,
the cock H of which is closed by the said ball float G, Figure II. As the first
float F is lowered it opens the water outlet K. At this moment the receptacle A
is emptied and thus compels the ball float G to descend. In the downward
movement of this float the latter opens the cock H of the first float F to discharge
water which it contains at the same time as the water in the receptacle is let out.
The float being thus lightened rises by reason of the weight of the second float E
which re-descends and in this movement again opens the water admission pipe C
connected with the three-way cock and closes the water outlet, K. At this
moment the water enters the receptacle A and compresses the air again.
It will be seen that the movement is purely automatic and continuous as long as
it is actuated by any water pressure. When this pressure becomes too great for
the purposes for which the apparatus is designed it will be automatically regulated
by a device which comprises a box L containing a cock or valve M and connected
with a water admission pipe N and outlet pipe o joined to a pipe P for the
introduction of the water into the receptacle A. A lever Q Q adapted to turn

page_text: upon a pivot R and carrying a weight S regulates the pressure when water enters
the said box L.
The water expands the chamber T by compressing the air therein which acts
upon a lever Q by means of a pin or rod U. The said lever QQ also acts by
means of a second rod V upon the before-mentioned valve W the said rod passing
through a stuffing box in the box L and communicating with the interior thereof.
This valve is made of sheet copper or other metal or material by soldering or
otherwise uniting two, round, oval, square or other shaped parts upon each other.
This combination is such that the further the weight S is moved towards the
extremity of the aforesaid lever QQ the more pressure will be exerted upon the
expansible chamber T the valve M being at the same time opened wider to allow
more water to pass into the box L and enabling a greater pressure to be obtained.
The contrary effect is obtained if the weight is moved towards the said expansible
chamber T. As this takes place the weight exerts indirectly a pressure upon the
valve M by the rod V which prevents the entrance of the water and thus
regulates the pressure to as many atmospheres as may be desired by the simple
displacement of the weight. A bell ✗ is provided at the upper part of the
receptacle, forming an air purifier through which the air enters the said receptacle,
passing on its way through a pressure and suction valve. The receptacle is further
provided with an air pipe B B for the supply of the compressed air to the place
where it is to be utilized, also with pipes C C for introducing the air into the
receptacle, and with a pressure gauge D¹.
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 :-
An air compressing apparatus constructed, arranged and operating substan-
tially as hereinbefore described with reference to the drawing and for the purpose
