Improvements in Pumps for Raising or Forcing Fluids or Semi-
fluids.
I JOHN SEATON WARBURTON of 49 New Road, Grays, in the county of Essex,
Mechanical Engineer do hereby declare the nature of my said invention to be as
follows:-
-0
The application to pumps for raising or forcing fluids or semi-fluids of an injection
of water or other suitable fluid (under a head or pressure equal to or in excess of the
head or pressure of the fluid or semi-fluid which is being raised or forced) at a point
within the stuffing box of the pump or at a point between the stuffing box and the
working barrel of the pump for the purpose of preventing the fluid or semi-fluid
matter within the working barrel of such pump from coming into contact with the
packing or gland of the stuffing box and for the purpose of washing away grit or
other matter from the working surface of the plunger or piston rod and for the
purpose of keeping the working barrel primed with fluid or semi-fluid ready for work.
This invention is more especially intended for application to pumps for raising or
forcing "slurry" in cement works or in the manufacture of bricks but it may be
applied to pumps for raising or forcing tar oils acids or other fluids or semi-fluids to
prevent them from coming in contact with the packing or gland of the stuffing
box.
The head or pressure of the water or other fluid of injection may be obtained by
gravity or by a force pump or otherwise.
Suitable accessory apparatus may be provided for the purpose of regulating
controlling measuring or registering the supply of the injection water or other fluid
or of the fluid or semi-fluid which is being raised or forced and all or any part of such
accessory apparatus may be automatically controlled by the working pump or may
control the working pump or otherwise.
The water or other fluid of injection may be arranged to pass through the interior
of the plunger piston rod or piston of the pump and be injected from such plunger
piston rod or piston instead of being injected from the stuffing box or casing of the
pump or the injection may be made simultaneously at all or any of such points in
the plunger piston rod or piston and the stuffing box or casing of the pump as
described.

Improvements in Pumps for Raising or Forcing Fluids or Semi-
fluids.
I, JOHN SEATON WARBURTON of 49 New Road, Grays in the County of Essex
Mechanical Engineer do hereby declare the nature of my Invention for IMPROVE-
MENTS IN PUMPS FOR RAISING OR FORCING FLUIDS OR SEMI FLUIDS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention consists in the application to pumps for raising or forcing fluids or
semi fluids of an injection of water or other suitable fluid (under a head or pressure
equal to or in excess of the head or pressure of the fluid or semi fluid which is being
raised or forced) at a point within the stuffing box of the pump or at a point between
the stuffing box and the working barrel of the pump for the purpose of preventing
the fluid or semi fluid matter within the working barrel of such pump from coming

into contact with the packing or gland of the stuffing box and for the purpose of
washing away grit or other matter from the working surface of the plunger or piston
rod and for the purpose of keeping the working barrel primed with fluid or semi
fluid ready for work. This invention is more especially intended for application to
pumps for raising or forcing "slurry" in cement works or in the manufacture of
bricks but it may be applied to pumps for raising or forcing tar oil acids or other
fluids or semi fluids to prevent them from coming in contact with the packing or
gland of the stuffing box. The head. or pressure of the water or other fluid of
injection may be obtained by gravity or by a force pump or otherwise. Suitable
accessory apparatus may be provided for the purpose of regulating controlling
measuring or registering the supply of the injection water or other fluid or of the
fluid or semi fluid which is being raised or forced and all or any part of such
accessory apparatus may be automatically controlled by the working pump or may
control the working pump or otherwise.
The water or other fluid of injection may be arranged to pass through the interior
of the plunger piston rod or piston of the pump and be injected from such plunger
piston rod or piston instead of being injected from the stuffing box or casing of the
pump or the injection may be made simultaneously at all or any of such points
in the plunger piston rod or piston and the stuffing box or casing of the pump as
described.
Referring now to the accompanying descriptive drawings :—
Fig. 1. is a vertical section of a ram or plunger pump having an annular chamber
or passage d formed in the body of the pump at a point between the stuffing box
and the working barrel to which a stream of water or other fluid or semi fluid is
admitted by the inlet a so as to encircle the working face of the plunger a with a
"water belt" which serves to carry away any grit which escapes through the exit g
and so prevent the access of grit to the packing within the stuffing box.
Fig. 2. is a vertical section of a similar plunger pump in which water or other
fluid or semi fluid entering at a is admitted by a regulating cock or valve from
whence it passes through an inlet c formed at the side of a "water belt ring" w made
of metal or other suitable material to an annular chamber or passage d formed in the
inner surface of the said "water belt ring" so as to encircle the working face of
the plunger with a "water belt" which serves to carry away any grit by
means of the outlet e through a loaded relief valve f. to the exit g. as above
described.
The relief valve f. is fitted in order that the pressure of water or other liquid or
semi liquid passing through the "water belt" may be applied at a head or pressure
equal to or in excess of the maximum pressure of the fluid or semi fluid which is
being raised or forced by the pump.
Fig. 3. is a cross section with plan of the "water belt ring" w. on an enlarged
scale:
Fig. 4. is a vertical section of a piston pump to which the description given in
fig. 1. applies excepting that the piston rod y. takes the place of the plunger and
-the water or other liquid or semi liquid entering the chamber d. by the inlet a
encircles the said piston rod y. and then escapes by the exit g.
Fig. 5. is a vertical section of a piston pump to which the description given in
fig. 2. applies excepting that the piston rod y takes the place of the plunger a.
Fig. 6. is a vertical section of a plunger pump similar to fig. 1. to which the
description given applies but in this case the rear end of the working plunger is
prolonged to form a small auxiliary force pump for the purpose of supplying the water
or other liquid or semi liquid forming the "water belt" to the inlet a and chamber d
as before described..
Fig. 7. is a vertical section of a plunger pump to which the description given in
fig. 2. applies with the addition of the description given in fig. 6. as to the object of
the prolongation of the rear end of the working plunger.
Fig. 8. is a vertical section of a piston pump having an annular chamber d. formed
"within the bush m between the stuffing box and the working barrel of the pump to

page_text: which annular chamber d the water or other liquid or semi liquid is admitted by the
inlet a so as to encircle the piston rod y with a "water belt" before escaping by the
exit g. The rear end of the piston rod y. is prolonged in the form of a hollow tube i
in order to allow water or other fluid or semi fluid to enter at h and pass along i to
points of exits k k¹ for the purpose of cleansing the working faces of the piston z.
Figures 9. 10. 11 and 12 show various forms of metallic or other "water belt
rings" w of which Fig. 9. is a cross section and plan of a (6 water belt ring" made
in two parts to allow of its being fitted in place within the stuffing box without
necessitating the removal of the working plunger or piston rod.
Fig. 10. is a vertical section of a "water belt ring" w. having two (or more)
annular chambers or passages d. d' arranged so that the water or other liquid or semi
liquid entering at a is made to pass in close contact with the working face of the
plunger or piston rod before escaping at the outlet e.
Fig. 11. is a sectional view of a "water belt ring" w having two (or more)
annular chambers or passages d d to which water or other liquid or semi liquid may
be admitted either alternately or simultaneously.
"
Fig. 12. is a sectional view of a "
water belt ring w having two (or more)
annular chambers or passages d d' arranged after the manner of a spiral or screw so
that the water or other liquid or semi liquid forming the "water belts" partially or
fully encircles the working face of the plunger or piston rod by means of the annular
chambers d. d¹ before escaping by the outlets e e¹.
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 application to pumps for raising or forcing fluids or semi fluids of an injection
of water or other suitable fluid (under a head or pressure equal to or in excess of the
head or pressure of the fluid or semi fluid which is being raised or forced) at a point
within the stuffing box of the pump or at a point between the stuffing box and the
working barrel of the pump for the purpose of preventing the fluid or semi fluid
matter within the working barrel of such pump from coming into contact with the
packing or gland of the stuffing box and for the purpose of washing away grit or
other matter from the working surface of the plunger or piston rod and for the
purpose of keeping the working barrel primed with fluid or semi fluid ready for
work.
2. The application to pumps for raising cement "slurry" or "slip" of an injection
of water or other suitable fluid or semi fluid substantially as and for the purposes
shown and described.
"
3. The arrangement and combination of a water belt ring," formed of metal or
other suitable material having one or more chambers d d¹ and provided with suitable
inlets c and outlets e for the purpose of admitting water or other fluid or semi fluid
to the working faces of the plunger or piston rods of pumps substantially as and for
the purposes shown and described.
4. The arrangement and combination of one or more annular chambers or partially
annular chambers d d' at a point between the stuffing box and the working barrel of
a pump substantially as and for the purposes shown and described.
5. The arrangement and combination of a suitable regulating cock or valve b with
one or more annular chambers d d¹ substantially as and for the purposes shown and
described.
6. The arrangement and combination of a suitable loaded or weighted relief valve f
with one or more annular chambers d d' substantially as and for the purposes shown
and described.
7. The arrangement and combination of a prolongation at either end of a plunger
or piston rod of a pump in order to form an auxiliary pump for supplying water or
other liquid or semi liquid to the "water belt" substantially as and for the purposes
shown and described.

page_text: 8. The arrangement and combination of a prolongation at either end of the piston
rod of a pump in form of a hollow tube in order to admit. water or other liquid or
semi liquid to the interior of the piston substantially as and for the purposes shown
and described.
9. The arrangement and combination within the stuffing box of a pump of one or
more "water belt rings" w made of metal or other suitable material in one or more
parts or sections and having one or more annular chambers or grooves d d' or their
equivalent formed within the inner surface of the rings substantially as and for the
purposes shown and described.
