County of York for an Invention of "IMPROVEMENTS IN HYDRAULIC AND
OTHER PUMPS "
PROVISIONAL SPECIFICATION left by the said William Henry Watson at
the Office of the Commissioners of Patents on the 8th September 1883.
WILLIAM HENRY WATSON of Horsforth near Leeds in the County of York
"IMPROVEMENTS IN HYDRAULIC AND OTHER PUMPS
"
My improvements have reference to pumps generally and the object of such
improvements is to dispense with the ordinary stuffing boxes or packing glands
employed for preserving the pump rods tight in the ends of the pump cylinder or
barrel. My improvements are also applicable to ram pumps.
In order to preserve the pump rod tight in the cylinder or barrel end, according
to my invention I apply a split ring or rings on the cylinder or barrel end and
round the pump rod. Each ring is made to fit close to the pump rod by external
pressure. The periphery of the rings are made by preference slightly taper or
conical, and over them is fitted a cap the interior of which is bored taper to corre-
spond. On this being tightened down by bolts or screws the rings are pressed
against the pump rod to any desired extent.
Compensating springs may be employed on these bolts to prevent the rings
binding on the pump rod too much, at the same time to press the rings up against
the pump rod as it or the rings become worn down.
The rings may also be pressed up to the pump rod by means of set screws, acting
against short compensating spiral springs which act directly on the periphery of
the rings. Similar arrangements to those above described are employed in the
ends of the cylinder or barrel of pumps with ram or plunger piston for keeping the
ram or plunger piston of the pump tight.

IMPROVEMENTS IN HYDRAULIC AND OTHER PUMPS
My Improvements have reference to pumps generally and the object of such
improvements is to dispense with the ordinary stuffing boxes or packing glands
employed for preserving the pump rods tight in the ends of the pump cylinder or
barrel. My Improvements are also applicable to ram pumps
In order to preserve the pump rod tight in the cylinder or barrel end according
to my Invention I apply a split ring or rings on the cylinder or barrel end and
round the pump rod. Each ring is made to fit close to the pump rod by external
pressure. The periphery of the rings are made by preference slightly taper or
conical and over them is fitted a cap the the interior of which is bored taper to
correspond
On this being tightened down by bolts or screws the rings are pressed against the
pump rod to any desired extent
Compensating springs may be employed on these bolts to prevent the rings
binding on the pump rod too much at the same time to press the rings up against
the pump rod as it or the rings become worn down
The rings may also be pressed up to the pump rod by means of set screws acting
against short compensating spiral springs which act directly on the periphery of the
rings. Similar arrangements to those above described are employed in the ends of
the cylinder or barrel of pumps having ram or plunger pistons, for the purpose of
keeping the ram or plunger piston of the pump tight.
And in order that my Invention may be more completely understood reference is
given to the accompanying drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS
Fig 1 is a sectional elevation and Fig 2 is a plan of a pump with ordinary pump
piston rod having my Improvements applied thereto Fig 3 is a longitudinal section
and Fig 4 an end view of a plunger pump with my Improvements applied to the
ordinary pump cylinder cover. Fig 5 is a longitudinal section and Fig 6 an end
view shewing another arrangement or modification of my Improvements
In Figs 1 and 2 (which shews how my Improvements may be applied to the
piston rods of pumps now in use) a is the barrel or pump cover. In order to
preserve the pump piston rod 6 tight in the cover a I apply a split ring or rings c
in the cover a and round the rod b. The rings c are made to fit close against the
rod b by external pressure. For this purpose the outside of the ring or rings c is
made slightly conical and over them is fitted the cap d the interior of which is
bored taper to correspond On the cap d being tightened down by the bolts f
(screws or studs) the rings c are pressed against the rod b to any desired extent.
Compensating springs g may be employed on the bolts f to prevent the rings c
binding against the rod b too severely and at the same time to keep the rings c
pressed up to the rod b as they or the latter become worn
The above des ription and lettering is applicable to Figs 3 and 4 with the
exception that b refers to the plunger piston or ram.
Figs 5 and 6 shew another arrangement or modification of my Improvements in
which a is the barrel-or pump cover which is fastened close and tight against the

page_text: end of the pump barrel. 6 is the plunger or ram of the pump c is the split ring
or rings, d are spiral springs and e are set screws By means of the set screws e the
springs & may be compressed and thereby the rings c are forced against the ram b
with the required degree of pressure. The cover a is recessed in such a manner
that the rings c are retained in position.
Having now described the nature of my said Invention and shewn by the aid of
drawings how the same may be carried into practice I would have it understood
that I do not limit myself to the precise details and configuration of the parts I have
described and shewn as the same may be varied or modified without departing in
any way from the nature of my Invention; what I do claim is
The arrangement and application of the ring or rings c to the piston rods
and plungers of hydraulic and other pumps, and the means employed for
imparting the required pressure to the same substantially as and for the purpose
herein set forth.
In Witness whereof I the said William Henry Watson have hereunto
set my hand and seal this twenty sixth day of December in the year of
Our Lord one thousand eight hundred and eighty three.
