An Improved Valve Controlling Device.
JOSEPH FRANKLIN BATCHELOR, Mechanical and Electrical Engineer, residing at
Number 138 Livingston Street in the City of Brooklyn, County of Kings and State
of New York, United States of America do hereby declare the nature of this invention
to be as follows:-
My invention relates to improved means for the operation of valves controlling
pressure in pipes.
Heretofore valves have been opened by screw-threaded stems or lever, connected
with the valve-head, power being applied manually to unseat the valve-head to
permit pressure to pass through the valve. I purpose controlling a valve which
may be opened manually as heretofore, and also by the operation of an auxiliary
valve controlled by the armature of an electromagnet in circuit with a circuit
controller.
I have illustrated my invention in the accompanying drawing in which like letters.
refer to like parts.
Figure 1 is a sectional view of the valve shown closed.
Figure 2 is a perspective view of the auxiliary valve stem and connections.
A is a valve chest, with supply port a¹ and exhaust port a 2, the valve seat a 3
and a 3 within which is the valve port a 4, this chest is also made with the
aperture a 5 and a 5 and port a 6 leading from the main supply of pressure.
B is a cylinder, preferably made as part of the valve chest A of a diameter
somewhat greater than the aperture a 5 and a 5 in the chest, the cylinder head 61
preferably secured to the cylinder B by the screws 62 and 62. The cylinder B is
provided with the ports 63 and 64.
C is a cylindrical plunger, one end of which, c' is adapted to fit the cylinder B
as a piston head, and the other end, e 2 adapted to fit the valve seat a 3 and a 3
as a valve head and arranged also to fit closely the aperture in the valve chest a 5
and a 5.
c3 is a spiral spring interposed between the head of the cylinder & and the
plunger or valve head c¹ having its tension directed to maintain the valve head
seated.
c4 is a valve stem secured to the valve head c 2 and passing through the valve
chest A.
D is a lever pivoted at d and engaging the valve stem c4 with a pressure to open
or unseat the valve.
E is an auxiliary valve intended to control pressure to the cylinder B, in the
channel between the ports a 6 and 63, in which e¹ is a valve chest having a cylindrical
aperture to receive the piston head e 5 described hereafter. e 2 is a valve stem, carrying
a valve head e 3, à perforated slide valve e t and a piston head e 5. This valve stem
and ports are shown in perspective in Figure 2, where it will be noted that the
perforated slide valve head e 4 is made with apertures e 9 and e 9, through which the -
pressure may exhaust, as will be hereinafter described.
The piston head e 5 carries an armature e 6.

page_text: The valve chest el has three ports, one connecting with the port a 6, one connecitng
with the port 63 and one e leading from the valve chest e', operating as an exhaust.
e 8 is also an exhaust port, leading from before the piston head e 5.
F is a lever pivoted at 1 and engaging one end of the valve stem e 2. e 10 is
a spiral spring interposed between the valve head e5 and the head of the cylinder
in which it operates.
.
G is an electro magnet in circuit, the circuit connections and the means to control
the same being shown as a 2a and a. The core of the magnet y being
extended and provided with a screw thread is screwed through the head of the
cylinder, which is preferably formed of a non-magnetic material. The operation of
the valve and its controlling devices is as follows:
Normally the valve is in the position shown in Figure 1, the valve being retained
seated by the spring c 3. When pressure is introduced through port a' the position
is unchanged. The pressure then lies before the valve head c2 and also passes
through the port a 6, auxiliary valve chest E, port 63 into the cylinder B. It will
be noted that the pressure surface of the plunger presented to the pressure in the
cylinder B is greater than the pressure surface presented to the valve head c 2.
Therefore the valve will remain closed or seated.
The pressure surface presented by the valve head e3 and the piston head e 5 in
the auxiliary valve chest E are supposed to be equal, the spiral spring interposed
between the valve head e 5 and the head of the cylinder being directed to
maintain the valve head e 3 seated. Therefore, normally the port a is maintained
open to admit pressure into the cylinder B. When it is desired to open the valve
in order to permit pressure to pass through the valve and out of the port a 2, the
operation is as follows: The electric circuit is closed through the electro-magnet G,
whereby the same is energized, and the armature e 6 is attracted to the core gl against
the tension of the spring interposed between the valve head e 5 and the head of the
cylinder. The perforated sliding valve e 4 and the valve head e 3 are thereby brought
into an open position where the perforated sliding valve e4 closes the port a 6 and
the valve head e 3 opens the port e 7. The pressure then lying within the cylinder B
and auxiliary valve chest e is exhausted through the apertures in the perforated
sliding valve e4 and port e 7, and the pressure lying before the valve head c2,
causes the same to open and permit pressure to pass through the valve and out of
the port a 2.
The valve is again closed by breaking the circuit to the magnet G, when the
auxiliary valve E opens again as in Figure 1, and the increase of pressure in the
cylinder B presented to the greater pressure surface of the plunger C causes the valve
to be seated.
The port 64 is provided to exhaust any pressure that may escape between the
packing of the plunger.
I have described the way in which I control my valve electrically. I may also
control the same manually, by operating the auxiliary valve E by the pivoted lever F
or I may control the plunger C by means of the valve stem c4 and lever D.
It is apparent that I may omit or dispense with the perforated sliding valve e4
and yet operate the valve. I may further also omit or dispense with the piston
head e 5 on the valve-stem e² and still operate the valve, but by a greater expenditure
of magnetic energy to unseat the valve head e 3 and a great loss of pressure through
the port e 7 during the action of the valve as compared with the arrangement of
parts heretofore described and set forth.

page_text: An Improved Valve Controlling Device.
I, JOSEPH FRANKLIN BATCHELOR of 138 Livingston Street, Brooklyn in the
County of Kings and State of New York, United States of America, Mechanical
and Electrical Engineer, 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 improved means for the operation of valves controlling
pressure in pipes.
Heretofore valves have been opened by screw-threaded stems or lever, connected
with the valve-head, power being applied manually to unseat the valve-head to
permit pressure to pass through the valve, I purpose controlling a valve which
may be opened manually as heretofore or by the operation of an auxiliary valve
controlled by the armature of an electromagnet in circuit with a circuit controller.
The invention will be understood from the following description, reference being
had to the drawings accompanying the Provisional Specification, in which,
Figure 1 is a sectional view of the valve shown closed; and
Figure 2 is a perspective view of the auxiliary valve stem and connections.
A is a valve chest with supply port a' and exhaust port a², the valve seat a³ and a³,
within which is the valve port a. This chest is also made with the aperture a
and a and port a leading from the main supply of pressure. B is a cylinder,
preferably made as part of the valve chest A, of a diameter somewhat greater than
the aperture a and a in the chest, the cylinder head preferably secured to the
cylinder B by the screws and 2. The cylinder B is provided with the ports b³
and . C is a cylinder plunger, one end of which c¹ is adapted to fit the cylinder B
as a piston head, and the other end c2 adapted to fit the valve seat a³ and a3 as a
valvo head, and arranged also to fit closely the aperture in the valve chest a³ and a.
c3 is a spiral spring interposed between the head of the cylinder and the plunger or
valve head e' having its tension directed to maintain the valve head seated. c is a
valve stem secured to the valve head and passing through the valve chest A.
D is a lever pivoted at d and engaging the valve stem with a pressure to open
or unseat the valve. E is an auxiliary valve intended to control pressure to the
cylinder B, in the channel between the ports a and 3 in which e' is a valve chest
having a cylindrical aperture to receive the piston head e described hereafter. e is
a valve stem carrying a valve head e³, a perforated slide valve e and a piston
head e. This valve stem and ports are shown in perspective in Figure 2, where it.
will be noted that the perforated slide valve head e is made with apertures e³ and e
through which the pressure may exhaust, as will be hereinafter described.
The piston head carries an armature e. The valve chest el has three ports one
connecting with the port a, one connecting with the port 3 and one e' leading from
the valve chest el operating as an exhaust, es is also an exhaust port leading from
before the piston head es. F is a lever pivoted at f¹ and engaging one end of the
valve stem e². 10 is a spiral spring interposed between the valve-heade and the
head of the cylinder in which it operates.
G is an electro magnet in circuit, the circuit connections are shown as X and X2,
and the battery or other electric source as X and the means to control the circuit
is indicated as X. The core of the magnet gl being extended and provided with a
screw thread, is screwed through the head of the cylinder, which is preferably formed
of a non-magnetic material.
The operation of the valve and its controlling devices is as follows:-
Normally the valve is in the position shown in Figure 1, the valve being retained
seated by the spring c³. When pressure is introduced through port a¹ the position

page_text: is unchanged. The pressure then lies before the valve head and also passes
through the port a", auxiliary valve chest E, port 63 into the cylinder B. It will be
noted that the pressure surface of the plunger presented to the pressure in the
-cylinder B is greater than the pressure surface presented to the valve head c².
Therefore the valve will remain closed or seated. The pressure surface prosented by
the valve head e³ and the piston head es in the auxiliary valve chest E are supposed
to be equal, the spiral spring interposed between the valve head'es and the head of
the cylinder being directed to maintain the valve head e3 seated. Therefore, normally
the port a is maintained open to admit pressure into the cylinder B. When it is
desired to open the valve in order to permit pressure to pass through the valve and
out of the port a², the operation is as follows:-The electric circuit is closed through
the electro magnet G by operating the circuit closer whereby the said magnet is
energised, and the armature e is attracted to the core g' against the tension of the
spring interposed between the valve head e and the head of the cylinder. The
perforated sliding valve e and the valve head e³, are thereby brought into an open
position, where the perforated sliding valve e closes the port a and the valve
head opens the port e'. The pressure then lying within the cylinder B, and
auxiliary valve chest E is exhausted through the apertures in the perforated sliding
valve e and port e', and the pressure lying before the valve head e, causes the same
to open and permit pressure to pass through the valve and out of the port ². The
valve is again closed by breaking the circuit to the magnet G, when the perforated
slide valve e resumes its normal position and the valve head e3 is seated, as in
Figure 1, thus permitting the admission of pressure to the cylinder B, when the
piston c will cause the main valve to close because of the greater pressure surface
presented by said piston. The port 4 is provided, to exhaust any pressure that may
escape between the packing of the plunger.
I have described the way in which control my valve electrically. I may also
control the same manually by operating the auxiliary valve E by the pivoted lever F
or I may control the plunger C by means of the valve stem e and lever D.
I have described the above way of carrying my invention into effect, but it is
obvious that I may make certain alterations in detail without departing from the
principle of the invention. Thus for example it is apparent that I may omit or
dispense with the perforated sliding valve e and yet operate the valve. I may
further also omit or dispense with the piston head e on the valve stem e² and still
operate the valve, but by a greater expenditure of magnetic energy to unseat the
valve head e³, and a great loss of pressure through the port e' during the action of
the valve as compared with the arrangement of parts heretofore described and set
forth.
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. The improvement in or in connection with valves controlling pressure in
pipes, which consists in forming the main valve with a plunger or its equivalent
arranged to present greater pressure surface on one side than the other, so that
normally the valve will remain closed or seated, in combination with an auxiliary
valve adapted to simultaneously control the supply and exhaust of pressure to one
side of the said main valve, and means for operating said auxiliary valve, whereby
when the pressure on one side of the main valve is exhausted by the said auxiliary
valve, the pressure lying on the other side will cause the main valve to open and
permit pressure to pass through the delivery port substantially as described.
2. In a valve controlling device, the combination with a main balance valve of an
auxiliary valve having a valve stem carrying a perforated slide valve, and a disc
valve adapted to simultaneously control the supply and exhaust of pressure to one
side of the main valve and means to operate said auxiliary valve, substantially as
described.
3. In a valve controlling device, the combination with a main balance valve of an

page_text: auxiliary valve having a valve stem carrying a perforated slide valve and a disc
valve, adapted to simultaneously control the supply and exhaust pressure to one
side of the main valve, an electro-magnet in circuit, and means to control said circuit,
and an armature, for said magnet secured to the auxiliary valve stem, substantially
as described.
4. In a valve controlling device, the combination of a valve chest, A, and a
cylinder B, having valve seat and ports with a plunger C interposed between the
pressure in the valve chest, and the pressure in the cylinder, said plunger presenting
greater pressure surface to the pressure in the cylinder than to the pressure in the
valve chest, and adapted to be scated in the valve seat, an auxiliary valve casing E
interposed in the supply of pressure to the cylinder, said casing carrying a perforated
slide valve e and a disc valve e, with means to operate said valves e and e³,
substantially as described.
5. In a valve controlling device, the combination of a valve chest A and a
cylinder B, having valve seat and ports with a plunger C interposed between the
pressure in the valve chest and the pressure in the cylinder, said plunger presenting
greater pressure surface to the pressure in the cylinder than the pressure in the
valve chest and adapted to be seated in the valve seat, an auxiliary valve casing E,
interposed in the supply of pressure to the cylinder, said casing carrying a perforated
slide valve and a disc valve e secured to a valve stem e, an electro magnet in
circuit with means to control said circuit, an armature for said magnet secured to
the valve stem e substantially as described.
