WILLIAM MORGAN-BROWN, Patent Agent, of 38, Southampton Buildings, London,
"IMPROVEMENTS IN VALVES FOR STEAM AND OTHER FLUIDS, AND IN THE MEANS
FOR OPERATING THE SAME.' [A communication from abroad by John Theobald
Hancock, Civil Engineer, and William Robert Park, Mechanician, both of Boston,
Massachusetts, United States of America.]
This Invention relates to improvements in valves and the means of operating
the same. It is designed more particularly to be used in connection with apparatus
for lifting and forcing liquids, and with especial reference to the Patent granted to
J. T. Hancock for an inspirator granted by the United States Patent Office,
January 2, 1877.
The object of the Invention is to provide a means for opening two or more
orifices successively for the passage of steam or other fluids by the continuous
movement of a single connection or valve stem in such a manner that one valve
shall be opened in advance of the other, by which means, as adapted to the said
Hancock inspirator, the steam which enters the first steam passage will operate the
lifting apparatus and that which afterwards enters the second steam passage will
operate the forcing apparatus. The Invention consists in the combination of two
or more separate valves having a rigid connection with each other, the relative
position of the said valves to the orifices which they open and close being such that
their movement shall cause the orifices to be successively opened for the purpose of
Price 6d1

or others.
Referring to the Drawings,-
Figure 1 represents a longitudinal vertical section of a valve embodying the
improvement.
Figure 2 is a transverse vertical section on the line x, y, of Figure 1.
Figure 3 is an end view.
A is the head or valve casing composed of metal and cast in one piece; D is the
steam supply passage; B is a steam passage connecting with passage D and leading
to the lifting apparatus; C is a steam passage also connecting with passage D and
leading to the forcing apparatus, the respective connections being indicated by
dotted lines in Figure 2.
G is a seated valve opening and closing the orifice of the passage B; H is a
piston valve rigidly attached to the valve G by the connection E and opening the
orifice of passage C; F is the valve-stem connected to the valve G by means of a
union nut I. On the valve-stem F is a screw thread J, which is fitted to work in
the valve-stem nut k. The nut k screws into the head A and at its opposite end
has a packing cap L, as shown. M is a collar or sleeve surrounding a portion of
the valve-stem nut k, and is provided with a handle R; N is a nut for holding the
sleeve M in position on the valve-stem nut K. To the outer end of the
valve-stem F is attached a link O, provided at its upper end with a curved
slot O', as shown in Figure 3. In the slot O' of the link O is secured by means of
a set screw the head of a pin or cylindrical bar P, which pin is arrangeà parallel to
the valve-stem F and passes through an opening in the collar or sleeve M so as to
move freely therein longitudinally. Qreprésents a pipe attached to a projection on
the sleeve M, and is to be connected with an overflow or other pipe below (not
shown in the Drawing).
R is a lever or handle attached to the sleeve M. By means of the connection of
the pin I with the sleeve M. The movement of the lever is transferred to the
valve-stem F to operate the valves, the longitudinal movement of the threaded stem
being permitted by the pin I sliding in the sleeve M the relation between the
valves G, H, and the lower or overflow pipes is governed by means of the adjustment
of the pin P in the slot O¹ of the link O.

IMPROVEMENTS IN VALVES FOR STEAM AND OTHER FLUIDS, AND IN THE MEANS
FOR OPERATING THE SAME." A communication from abroad by John Theobald
Hancock, Civil Engineer, and William Robert Park, Mechanician, both of Boston,
Massachusetts, United States of America.
This Invention relates to improvements in valves and the means of operating
the same.
It is designed more particularly to be used in connection with apparatus
for lifting and forcing liquids, and with especial reference to the Patent granted to
John Theobald Hancock for an inspirator granted by the United States' Patent
Office January 2nd, 1877.
The object of the Invention is to provide a means for opening two or more
orifices successively for the passage of steam or other fluids by the continuous
movement of a single connection or valve stem in such a manner that one valve
shall be opened in advance of the other, by which means as adapted to the said
Hancock inspirator the steam which enters the first steam passage will operate the
lifting apparatus, and that which afterwards enters the second steam passage will
operate the forcing apparatus. The Invention consists in the combination of two
or more separate valves having a rigid connection with each other, the relative
position of the said valves to the orifices which they open and close being such that
their movement shall cause the orifices to be successively opened for the purpose
of allowing the passage of the fluid first to one or more conduits and then to the
other or others.
Referring to the Drawings, Figure 1 represents a longitudinal vertical section of
a valve embodying the improvement. Figure 2 is a transverse vertical section on
the line x, y, of Figure 1; Figure 3 is an end view.
A is the head or valve casing composed of metal and cast in one piece; D is the
steam supply passage; B is a steam passage connecting with passage D and leading
to the lifting apparatus; C is a steam passage also connecting with passage D and
leading to the forcing apparatus, the respective connections being indicated by
dotted lines in Figure 2; G is a seated valve opening and closing the orifice of the
passage B; H is a piston valve rigidly attached to the valve G by the connection E
and opening the orifice of passage C; F is the valve stem connected to the valve G
by means of a union nut I. On the valve stem F is a screw thread J, which is
fitted to work in the valve stem nut K. The nut K screws into the head A, and
at its opposite end has a packing cap L, as shown. M is a collar or sleeve
surrounding a portion of the valve stem nut K and is provided with a handle R;
N is a nut for holding the sleeve M in position on the valve stem nut K.
To the outer end of the valve stem F is attached a link provided at its upper
end with a curved slot O¹, as shown in Figure 3. In the slot O¹ of the link O is
secured by means of a set screw the head of a pin or cylindrical bar P, which pin
is arranged parallel to the valve stem F and passes through an opening in the
collar or sleeve M so as to move freely therein longitudinally; represents a pipe
attached to a projection on the sleeve M and is to be connected with an overflow
or other pipe below (not shown in the Drawing).
R is a lever or handle attached to the sleeve M. By means of the connection of
the pin I with the sleeve M. the movement of the lever is transferred to the valve
stem F to operate the valves, the longitudinal movement of the threaded stem
being permitted by the pin I sliding in the sleeve M. The relation between the

page_text: valves G, H, and the lower or overflow pipes is governed by means of the adjustment
of the pin P in the slot O¹ of the link O.
Having now described and particularly set forth the nature of the said Invention,
and the manner of carrying the same into effect, I would have it understood that
what I claim is,—
1st. The combination of two or more separate valves, one of which is a seated
valve and the other a piston valve, rigidly attached together, substantially as
described and arranged in relation to the orifices which they successively open or
close, substantially as and for the purpose set forth.
2nd. The seated valve G and piston valve H connected together by a stem E in
combination respectively with the independent and separate passages B and C,
substantially as and for the purpose specified.
3rd. The combination of the valve stem F, provided with the screw thread J,
the nut K, sleeve N, and lever M, connected to the valve stem by a pin P and
arm O, substantially as and for the purpose set forth.
4th. The combination of the lever M, the adjustable pin P, the slotted arm O,
and the valve stem F, substantially as and for the purpose specified.
5th. The combination with a valve stem and nut operating one or more valves
of an actuating lever, and an adjustable pin and a sleeve, substantially as set
forth.
In witness whereof, I, the said William Morgan-Brown, have hereunto set my
hand and seal, this Twentyeighth day of February, in the year of our
Lord One thousand eight hundred and eighty one.
