PROVISIONAL SPECIFICATION.
Improvements in the Construction of Working Valves and their
Connections, applicable to Water, Steam. Air, or Gas.
I, HENRY BERRY, of Croydon Works, Hunslet, Leeds, Hydraulic Engineer,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to overcome the difficulty which has hitherto been
experienced in the rapid and efficient opening and closing of working and other
valves.
In my invention, I employ to attain this object an auxiliary or working valve
which communicates with the main pressure valve, and is so arranged that by the
opening or closing of this same auxiliary valve the main pressure or outlet valve
is similarly opened or closed.
To effect this action I have a small passage of communication running on the
top side of both the auxiliary and main valves. Communication is also made to
the two valves from below each of their respective seats. The auxiliary or working
valve is actuated by means of a suitable cam and lever. The main pressure to be
controlled is admitted into the main inlet valve chamber below the top of the valve.
The action then briefly is as follows:-
The compressed fluid enters the valve chamber and accumulates on the top of
the main valve, closing it. To open the main valve, the auxiliary valve by means
of a suitable cam is lifted from its seat, and the accumulator pressure is then
released from the top of the main valve and flows through the auxiliary or working
valve to below the seat of the main valve. By thus exhausting the pressure from
the top of the main valve and no resistance being met with, the main pressure lifts
this same pressure valve from its seat and allows the main pressure free access to
the machine to be worked. This description refers only to stop valves, and this
invention is of extreme value when dealing with large mains at high pressure.
This invention, is also applicable for working valves of all descriptions. In a
single acting working valve for example, I duplicate the valves, that is, in the one
body I have two auxiliary valves and two main valves and make the communication
between the two main valves underneath the seat of the pressure or inlet valve to
the top of the seat of the exhaust or outlet valve. The auxiliary valves are
arranged to be worked by the same lever, the cams for each valve being so
designed that the one valve is never open at the same time as the other; sufficient
lap or clearance being left so that when the lever stands in the centre of its stroke
both valves are closed.
This system can also be adapted to double acting valves which can also be
actuated by one lever.
My invention is also applicable for the automatic working of a plate closing
cylinder of a hydraulic rivetting machine which by means of a release valve
thrown into action automatically when the maximum working pressure in the
working or rivetting cylinder is reached, this being effected by means of a small
ram attached to a double faced valve the cylinder of which is connected to the
main cylinder pressure. The ram is inade of such an area in relation to the valve
that the pressure in its cylinder overcomes that bearing on the valve and closes
the pressure going to the plate closing cylinders and at the same time opens it to
exhaust.
My invention is also applicable for working a machine in conjunction with an
"intensifier." The working valve is arranged with a clack or rack pressure valve,
fixed between the pressure valve and the outlet. In line with the clack valve is a

page_text: double seated valve connected with a small ram whose cylinder is always open to
constant pressure, and which forces the double faced valve against a seat which is
in direct communication with the pressure passing through the main pressure valve.
When the pressure in the main cylinder of the hydraulic press reaches its maximum
working pressure that pressure is also in communication with the intensifier valve
and is of sufficient area with the maximum cylinder pressure to overcome the small
ram connected with the constant pressure, forces the valve off its seat and allows
the valve pressure to go to the "intensifier" and at the same time closes its
exhaust. The pressure in the main cylinder being instantly increased the clack
valve drops in its seat, and locks the water in main cylinder enabling it to be
intensified.
To exhaust. The main pressure valve is closed and the exhaust or outlet valve
is opened. The pressure forcing the intensifier valve is shut off and the constant
pressure in the small cylinder again forces the valve on its seat shutting the
"intensifier" from pressure and at the same time opening it to exhaust.
Attached to the double faced valve is a finger which when closing also lifts the
clack valve and exhausts the main cylinder.

improvements applied.
Fig. 3. is a sectional elevation of "steam stop" valve, with my improvements
applied.
Figs. 4. and 5. are sectional clevations, and Fig. 6. a plan of hydraulic working
valve according to my invention.
Fig. 7. is a sectional elevation, and Fig. 8. a plan of double acting working valve
according to my improvements.
Figs. 9 and 10. show my improvements, for automatically throwing off the
constant pressure of a plate closing apparatus, or releasing constant pressure, when
the maximum pressure, in the main or rivetting cylinder is reached as for instance
when used in connection with a hydraulic rivetter and shown applied to my special
valve, but are equally applicable to any working valve of this nature. In the
figures Fig. 9. is a sectional elevation, through the main and auxiliary pressure

page_text: valves, and Fig. 10. is a part sectional plan showing the details of the automatic
shut-off.
Figs. 11. and 12 show my improvements for automatically throwing an intensifier
into operation, when the maximum working pressure is reached, applied to my
special construction of valve, but equally applicable for any working valve of this
nature. In these figures:-Fig. 11 is a sectional elevation and Fig. 12 a plan.
According to my invention, to effect this action, see Figs. 1. and 2, I provide a
passage of communication A across the main valve body B, in which body are
fitted the main valve C and auxiliary valve D, communication is also made to the
two valves C and D from below each of their respective seats, by means of a
passage E, leading into the outlet L along with the said passage A. The
auxiliary valve D is actuated by means of a suitable cam F, upon a shaft G, and
hand-lever H also upon the said shaft. The main pressure to be controlled is
admitted into the main inlet valve chamber J through the pressure inlet K below
the top of the main valve C.
The action is as follows:-
The compressed fluid enters the valve chamber J, through the inlet K, a portion
of it forces itself past and accumulates on the top of the main valve C so forcing
the main valve C on to its seat and thus shutting off communication of the pressure
through pressure outlet L..
To open the said main valve C, and to allow pressure to pass through the
pressure outlet L, the auxiliary valve D, by means of the cam F, upon the shaft G
and hand-lever H is lifted from its seat and the accumulated compressed fluid
(forcing the main valve C on to its seat) is then released from the top of the main
valve C and flows or forces itself through and round the auxiliary valve D, and
into the pressure outlet L, thus exhausting the fluid faster than it can accumulate
upon the top of the said valve C. By thus exhausting the pressure from the top
of the main valve C, and no resistance being met with, the main pressure lifts this
same pressure valve C from its seat and allows the main compressed fluid free access
to the machine to be worked through the outlet L. This description refers to
"stop" valves and this invention is of extreme value when dealing with large
mains at high pressure.
In Fig. 3 is shown a view of stop valve with my improvements applied for use
in connection with steam pressure. A is the passage of communication across the
main valve body B, in which body are fitted the main valve C (attached to which
is a piston C¹) and auxiliary valve D. Communication being made between the
two said valves by the passage A and a further passage E. The auxiliary valve D
is actuated by means of a suitable cam F, upon a shaft G, and hand-lever H, also
upon the said shaft. The steam pressure to be controlled is admitted into the
valve chamber J through the inlet K below the piston C¹.
The action is as follows:-
The steam enters through inlet K, into the valve chamber J, and passes between
the walls of the said chamber and the piston C¹ on to the top of the said piston,
and forces the main valve C on to its seating, thus closing the outlet L. To open
the said main valve or allow pressure to pass through it, the auxiliary valve D by
means of the cam F, upon the shaft G, and hand-lever His lifted from its seat,
the steam is then released from the top of the piston C¹ and flows or forces itself
through the auxiliary valve and passage E to below the seat of the main valve C,
faster than it can pass to the top of the piston C. By thus exhausting the steam
from the top of the piston C¹ the main valve C meeting with no resistance from
the top of the piston C¹ is lifted from its seat by the steam pressure aforesaid and
allows the steam to pass forward to do its work by the outlet L.
This invention is also applicable for working valves of all descriptions. In a
single acting working valve, see Figs. 4. 5 and 6, which show a bydraulic valve of
this nature I duplicate the valves, that is, in the one body B, I have two auxiliary
valves D and D', of which D' is the exhaust and two main pressure valves Č
and C, of which C¹ is the exhaust, and the passage of communication

page_text: is between the two main valves underneath the seat of the pressure or inlet valve,
to the top of the seat of the exhaust or outlet valve. A and E are passages
of communication from the pressure inlet K to the pressure outlet L and
regulated by the auxiliary valve D. Similar passages of communication are made
between the main and auxiliary exhaust valves.
The auxiliary valves D and D' are arranged to be worked by the same lever H,
the cams F for each valve being so designed that the one valve is never open,
at the same time as the other, sufficient "lap" or clearance being left so that when
the lever H, stands in the centre of its stroke, both of the said valves are closed.
G is the cam shaft on which are two cams which actuate alternately the auxiliary
valves D and D', M is the exhaust and J the pressure valve-box.
The action is as follows:-
The compressed fluid passes into the valve-box J through the inlet K and
pressure accumulates on the top of the valve C and closes it. To open, the
auxiliary valve D is lifted, exhausting the water from the top of the main valve C
and prevents as long as it is kept open any accumulation of water. The main
valve C then rises and admits pressure to the machine, at the same time the
outlet passage L is in communication with the valve-box passage Centering on
the top side of the said valve seat. The same action which has been gone
through with the valves C and D is followed out in the valves C and D¹. The
pressure which is passing through accumulates on the top of the main exhaust
valve C and closes it. To open to exhaust, the cam shaft G is moved, so as to
first close the auxiliary pressure valve, sufficient "lap" being allowed to allow
both auxiliary valves to remain closed. The exhaust auxiliary valve C is then
opened and water allowed to escape from the machine by the exhaust M, the
main pressure valve C in the meantime being closed.
The system can also be adapted to double acting valves, see Figs. 7 and 8,
which show a valve of this description which can also be actuated by one lever.
The description given with reference to Figs. 4. 5 and 6 applies substantially to
Figs. 7 and 8 there are two single acting working valves coupled together and
their auxiliary valves are so arranged as to be worked from one cam shaft, which
is adapted to open the exhaust of one valve, and the pressure of the other at the
same time and vice versa. C and C' are two main pressure valves, C3 and C4 are
two main exhaust valves, D and D' are, the two pressure auxiliary valves, D²
and D3 are the two exhaust auxiliary valves, L and L' are the two pressure
outlets, M and M' the two exhausts, K and K' the two pressure inlets, G the
cam shaft, H the hand-lever, F the cams, and A and E passages of communication.
My invention is also applicable see Figs. 9 and 10, for the automatic working of
a plate closing cylinder of a hydraulic rivetting machine, by means of a release
valve, thrown into action automatically when the maximum working pressure
in the working or rivetting cylinder is reached, this being effected by means of a
small ram attached to a double faced valve, the cylinder of which is connected to
the main cylinder pressure. The said ram is made of such an area in relation to
the valve that the pressure in its cylinder overcomes that bearing on the valve and
closes, the pressure going to the plate closing cylinders and at the same time
opens it to exhaust. C and C₁ are respectively the main pressure and exhaust
valves, D and D' are the auxiliary pressure and exhaust valves, E' is a chamber
in constant communication with pressure, being connected to the pressure valve-
box J by means of a passage J. J2 is the inlet to the plate closing cylinder.
J is a chamber provided for the exhaust from the plate closing or constant
pressure cylinder and is in direct communication with the exhaust from the main
exhaust valve indicated in dotted lines and lettered O. H' is a chamber in
communication with the main or rivetting cylinder. P is a plunger and double
headed valve combined. N is a passage of communication between E' and J.
R is a passage of communication between J and P.
The action is as follows:-
Pressure always in the chamber E' and the passage N is made somewhat

page_text: The
smaller than the area of the plunger P, which fits in the chamber H.
pressure in the chamber E' forces the plunger P on to the seat N' admitting
pressure through J' to the plate closing cylinder and shutting the exhaust at N
When the pressure in the rivetter cylinder reaches its maximum pressure, this
pressure in the chamber H', forces the plunger P back again on to the seat N'
shutting the plate closing cylinder off from the pressure and allowing it to exhaust
through K
My invention is also applicable for working a machine in conjunction with an
intensifier, see Figs. 11 and 12. The working or main pressure valve is arranged
with a clack or back pressure valve fixed between the pressure valve and the
outlet. In line with the clack valve is a double seated valve connected with a
small ram whose cylinder is always open to constant pressure, and which forces the.
double faced valve against a seat which is in direct communication with the
pressure passing through the main pressure valve. When the pressure in the main
cylinder of the hydraulic press reaches its maximum working pressure that
pressure is also in communication with the intensifier valve l' and is of sufficient
area with the maximum cylinder pressure to overcome the small ram connected
with the constant pressure forcing the valve P off its seat allowing the valve
pressure to go to the intensifier through outlet J and at the same time closing its
exhaust at S. The pressure in the main cylinder being instantly increased the
clack valve drops in its seat and locks the water in main cylinder, enabling it to
be intensified.
C and C are respectively the main pressure and exhaust valves and D and D¹
are respectively the auxiliary pressure and exhaust valves. E' is a clack non-return
valve in communication by passage P1 with the pressure valve C. P is a plunger
and double headed valve combined with a finger Q. J is the pressure outlet to
intensifier cylinder, J' is the exhaust and K³ is the constant pressure acting upon
the plunger Pat O'. H2 is the pressure outlet to the main cylinder of machine.
F is the main pressure inlet. R is a passage of communication from passage Pl
to chamber M. S is a passage of communication between chambers M¹ and N'.
The action is as follows:-
The constant pressure in chamber O' forces the plunger P up against the seat
at R shutting off all communication with the intensifier cylinder. Pressure is
passed through P¹ lifting the clack valve E' through H into the cylinder of the
machine. When the maximum pressure is reached in the cylinder the same
pressure is also necessarily bearing against the plunger P at R'. This is sufficient
to overcome the constant pressure at O' and to force the plunger Pou to the seat S
shutting off the intensifier cylinder from exhaust and opening it to pressure.
To exhaust, the pressure is shut off and the constant pressure at O' again forces
the plunger P up against the seat R' and allows the water from the intensifier
cylinder to escape through outlet J' at the same time the finger Q attached to the
plunger P lifts the clack valve E' and allows the main cylinder to exhaust also.

tion and in what manner the same is to be performed I declare that what I
claim is :-
