PROVISIONAL SPECIFICATION
Improvements in Pumps.
JOHN CHARLES RAYMOND OKES 39 Queen Victoria Street London E.C., Engineer
do hereby declare the nature of this invention to be as follows :-
Forming pumps and their accessories, especially for well and mine work, (but
which are suitable to other purposes) with one or more hollow plungers, the pump
part or parts constructed preferably in accordance with the Patent granted to me in
the year 1888 numbered 6.249, the rising main being formed with a swan neck above
the pump in such a manner that it may act as the attachments for the guides for the
rods actuating the pump plungers.
In cases where two or more pumps are employed I use two or more swan necks,
uniting into one rising main which serves for the pumps, and would also form the
base on which to fix the guides and in the case of two pumps with alternately acting
plungers, the rising main would provide the base upon which to attach the centre of
a vibrating lever.
The pumps may be actuated by cranks, levers or direct-acting engines or
otherwise.
COMPLETE SPECIFICATION.
Improvements in Pumps.
I JOHN CHARLES RAYMOND OKES of 39 Queen Victoria Street London in the
County of Middlesex 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:-
Forming pumps and their accessories especially for well and mine work (but which
are suitable to other purposes) with one or more, hollow plungers, the pump part or
parts constructed preferably in accordance with the Patent granted to me in the
year 1888 numbered 6,249 the rising main being formed with a swan neck above the
pump in such a manner that it may act as the attachment for the guides for the rods
actuating the pump plungers.
In cases where two or more pumps are employed I use two or more swan necks
uniting into one rising main, which serves for the pumps and would also form the
base on which to fix the guides-and, in case of two pumps with alternately acting
plungers, the rising main would provide the base upon which to attach the centre of
vibrating lever.
The pumps may be actuated by cranks, lovers or direct acting engines or
otherwise.
The pumps which are the subject of my improvements are more especially adapted
to wells and mines, or the like, though they are applicable to other purposes and
refer to pumps placed below ground operated from the surface either by cranks levers
or direct acting engines or other suitable means and consist of hollow plungers fitted
with valves and valve boxes which can be removed and for which a Patent No. 6249
dated 27 April 1888 was granted to me.
The subjoined drawings clearly illustrate my menning.
Figures I. II. III. and IV. represent a single pump the plungers of which may be
of equal or unequal diameters and the plungers may be operated by a forked rod as
in figures I. and II. or by single rods as in figures III. and IV. passing through a
stuffing box. Figures V., VI. & VII. represent double pumps of similar type
ונע

Similar letters apply to similar parts in each of the drawings.
A A' represent the hollow plunger.
B B' the valve box on same.
CC the suction valve boxes.
DD the delivery valvo boxes.
EE' the foot or retaining valve boxes.
FF the rising main.
GGG" the suction pipe.
HH the crank shafts.
Il the air vessels on rising main.
JJJ the vacuum vessels in suction pipes.
KK the vibrating boams.
LL' the swan necks on the rising mains.
The valve boxes BBC CBD and E E' are fitted with valves and seats in
accordance with my former Patent No. 6249 A.D. 1888 and the rising mains F F¹
are formed with swan nocks LL by which they can be used as supports for carrying
the guides for the pump rods.
I prefer placing a vacuum vessel JJJ" on the suction and an.air vessel [I'.on
the delivery pipes to equalize the flow of the water through the pipes and prevent
shocks.
In the case of the pump being driven directly from the steam cylinders placed
overhead use a vibrating beam or lever KK Figures VIII. & IX. the fulcrum of
which may be attached to the rising main or not as desired.
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. A hollow plunger pump or pumps in combination with the Patent No. 6249
granted to me 27th April 1888 constructed substantially as described and set forth.
2. In pumps the combination of a hollow plunger or plungers, the valves and
valve boxes of which are constructed in accordance with my Patent No. 6249-
27th April 1888 with a rising main formed with a swan neck as described and for
the purposes set forth.
Dated this 18th day of December 1889.
