1, JOHN TAYLOR, Managing Director, of Dowson, Taylor & Co. Limited,
Engineers, Blackfriars Bridge, Manchester do hereby declare the nature of this
invention to be as follows:-
One part of my invention consists in providing the plunger or ram of a pump
with an ordinary stuffing box placed inside the pump, and I extend the gland
thereof by a sleeve around the plunger or ram to the end of the cylinder or pump
chamber, and for the purpose of putting tension on the packing in the stuffing box
I bring through the pump casing from the outside one or more setting up screws
which come in contact with the end of the said stuffing gland extension or sleeve.
Where one setting up screw only is used I carry a bridge across the end of the
extension or sleeve and place the screw in a central position in the pump casing,
the screw being provided if necessary on the outside with a lock-nut and surrounded
by a casing. The extension piece or sleeve is perforated to allow the fluid pumped
to freely pass through and it may be longer or shorter according to the length of
the setting up screws or the particular disposition of the same on the outside of the
pump casing.
The essential feature of this part of my invention is, that only one stuffing box
and gland is provided located inside the pump chamber for a plunger or ram which
is double acting, and the adjustment of the packing is effected by one or more
tightening up screws from the outside of the pump.
Another part of my invention consists in making the suction or delivery valve of
the pump with a full way through the seating, and the various pieces self-locking.
I take an ordinary valve seat, which is generally screwed into the frame work of
the pump, and extend from it a yoke to a bridge above the valve outlet. The
centre of this bridge is provided with a hole, preferably screwed, into which a
nipple is screwed from the space between the bridge and the valve seating.
Through the nipple piece a hole is bored to suit the stem on the top of the valve
clack, and between the nipple and the valve clack there may be placed an ordinary
coiled spring. The parts are put together by taking the valve clack and placing
the nipple piece over the stem with the spring between.
Whilst the spring is compressed the whole is passed into the space between the
bridge and the valve seating with the clack on its seat, and the nipple piece is then
screwed into the bridge. The spring therefore has always to be compressed before
the nipple can be put in or taken out of the bridge it is therefore self-tightening
when the valve is working.
Dated this 5th day of November 1895.

I, JOHN TAYLOR, Managing Director, of Dowson, Taylor and Company
Limited, Engineers, Blackfriars Bridge, Manchester, in the County of Lancaster,
do hereby declare the nature of my said invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
One part of my invention consists in providing the plunger or ram of a pump with
an ordinary stuffing box placed inside the pump, and I extend the gland thereof by
a sleeve around the plunger or ram to the end of the cylinder or pump chamber,
and for the purpose of putting tension on the packing in the stuffing-box I bring
through the pump casing from the outside one or more setting up screws which
come in contact with the end of the said stuffing gland extension or sleeve. Where
one setting up screw only is used I carry a bridge across the end of the extension
or sleeve and place the screw in a central position in the pump casing, the screw
being provided if necessary on the outside with a lock-nut and surrounded by a
casing. The extension piece or sleeve is perforated to allow the fluid pumped to
freely pass through and it may be longer or shorter according to the length of the
setting up screws or the particular disposition of the same on the outside of the
pump casing.
The essential feature of this part of my invention is, that only one stuffing box
and gland is provided located inside the pump chamber for a plunger or ram which
is double acting, and the adjustment of the packing is effected by one or more
tightening up screws from the outside of the pump.
Another part of my invention consists in making the suction or delivery valve
of the pump with a full way through the seating, and the various pieces self-locking.
I take an ordinary valve seat which is generally screwed into the frame work of
the pump, and extend from it a yoke to a bridge above the valve outlet. The
centre of this bridge is provided with a hole, preferably screwed, into which a

placing the nipple piece over the stem with the spring between. Whilst the
spring is compressed the whole is passed into the space between the bridge and
the valve seating with the clack on its seat, and the nipple piece is then
screwed into the bridge. The spring therefore has always to be compressed
before the nipple can be put in or taken out of the bridge it is therefore self-
locking when the valve is working.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a longitudinal sectional elevation of my improvements in pumps, and
Fig. 2 a sectional elevation of suction and delivery valves.
A is the steam cylinder; B piston; C piston rod; D back cylinder cover;
E steam pipe; F exhaust pipe; G steam ports; H exhaust port; I valve-box;
J valve; K valve-box cover; L valve spindle; M double-acting pump; N ram or
plunger; O pump rod; P inlet pipe to pump; Q outlet or delivery pipe from
pump; R air vessel, and S the foundation plate.
The double-acting pump M is provided internally with the stuffing-box T,
through which the plunger or ram N travels to and fro according to the

page_text: stuffing-box T is attached the sleeve or arms V around the plunger or ram N
to the back end of the cylinder or pump chamber M for the purpose of putting
tension on the packing in the stuffing-box T. The outer ends of the sleeve or
arms V are attached to the cross-bar or bridge V₁-in any convenient manner-
and the gland U is operated to compress or otherwise the packing in the
stuffing-box T by means of the setting-up screw W which passes through the pump
cover X. The setting-up screw W is provided with the lock-nut Y to ensure of
the same being firmly fixed.
Another important part of this invention consists in making or constructing each
suction and delivery valve Z of the double-acting pump M with the full way or
passage A through the seating. Each valve seating Z is by preference screwed
into its respective position in the openings B₁ of the pump. From the valve.
seating Z extends the yoke C¹ to the bridge D¹ above the valve outlet. The
centre of the bridge D¹ is provided with a hole or opening in which is disposed
the nipple E. Through the nipple piece E¹ is bored the hole E2 to suit the
diameter of the stem F' on the top of the valve clack G', and between the
flange G on the nipple piece E¹ and the valve clack G¹ is disposed the coiled
spring H. Owing to it being necessary to compress the coiled spring H¹ before
the nipple piece E¹ can be placed in or taken out of the bridge D¹ it is therefore
self-locking when the clack valve G¹ is operating.

Each valve seating Z is screwed or secured into the passages or openings B¹
and B in the pump, and after the water or liquid has passed through the valves
in the seatings B2 into the chamber W' it is delivered into the pipe W* and through
the outlet and pipes coupled thereto to any desired point. To ensure an equal
flow and produce an uniform pressure of delivery the outlet pipe is provided with
the air vessel R. The chambers M and W³ are provided with the openings Z³ to
allow of the suction and delivery valves being placed in position or removed
therefrom, the said openings Z' being closed by the covers Z³.
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 general arrangement, construction, and combination of parts composing
my improvements in pumps, as hereinbefore described and as illustrated in the
annexed drawings.
2. In ram pumps the use of the stuffing-box T, gland U, sleeve or arms V and
cross bar V combined, the whole being operated from the back or outside of the
pump by the screw W for the purpose specified, substantially as described and as
illustrated in the drawings.
3. The use and construction of the self-locking valve as described and illustrated.
