LETTERS PATENT to Joseph Evans and William Evans, both of
Culwell Foundry, Wolverhampton, in the County of Stafford,
Hydraulic and General Engineers and Ironfounders, for the In-
D"
Scaled the 29th August 1871, and dated the 14th June 1871.
PROVISIONAL SPECIFICATION left by the said Joseph Evans and
William Evans at the Office of the Commissioners of Patents, with
their Petition, on the 14th June 1871.
WO, JOSEPH EVANS and WILLIAM EVANS, both of Culwell Foundry,
Wolverhampton, in the County of Stafford, Hydraulic and General
Engineers and Ironfounders, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN PUMPING MACHINERY," to be as follows:-
This Invention refers to an arrangement for the application of direct
action to pumps worked by hand, horse, steam, or other motive 'power,
and consists in employing a vertical shaft working in suitable bearings,
the said shaft being set in motion by a lever or by means of mitre, bevel,

page_text: worm wheel, or other gearing. The pump or pumps (if more than one
be used) is or are arranged horizontally, and may be of single or double
action, or of any suitable description, and fixed in any convenient
position either at the bottom or some distance up the vertical shaft
aforesaid. The said shaft may be of any suitable length and is provided 5
with a crank and pin, eccentric, or other suitable equivalent at its lower
extremity, and also at any point opposite to which a pump is fixed.
The said pump or pumps is or are worked from the said crank or cranks
or equivalent by means of ordinary connecting rods.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Evans and William Evans in the Great
Seal Patent Office on the 14th December 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
EVANS and WILLIAM EVANS, both of Culwell Foundry, Wolverhampton,
in the County of Stafford, Hydraulic and General Engineers and Iron- -
founders, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of June, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give ||
and grant unto us, the said Joseph Evans and William Evans, Her
special licence that we, the said Joseph Evans and William Evans,
our executors, administrators, and assigns, or such others as we, the
said Joseph Evans and William Evans, our executors, administrators,
and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS 'IN PUMPING MACHINERY,”
upon the condition (amongst 'others) that we, 'the said Joseph Evans
and William Evans, our executors or administrators, by an instru-
ment in writing under our, or their, or one of their hands and seals,
should particularly describe 'and 'ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in 'the, Great Seal Patent Office within six :

page_text: are connected together at their outer extremity, and a swingle tree
attached thereto as is done with certain other descriptions of portable
horse machines.
In order to facilitate the removing of the pump from place to place
the crank C is returned as shewn at H, and has a pin J working down- 5
. wards into the front axle and central with the vertical shaft A. A
projecting piece K is shewn on the crank pin end of the return crank H
having a hole therein which may be turned over a corresponding hole
in the front axle and a pin slipped into the holes when the pump is to
be removed, thus connecting the front axle with and working it radially 1
from the vertical shaft A. Slotts are provided in the side frames to
allow of the radial movement of the front axle.
Figures 3 and 4 illustrate respectively a side elevation in section,
and a front elevation of an arrangement for carrying the top of a
vertical shaft used for deep well pumping according to our said 1
Invention, and are drawn to a scale of one inch to a foot. A is the
vertical shaft working in the standard B`and provided at its upper.
extremity with a bevel wheel C. The under side of the said bevel
wheel O is carried on the friction rollers D, D, and thus the weight
or part thereof of the said vertical shaft A is carried on the friction 2
rollers D, D. The said bevel wheel C is worked by a bevel pinion E
on the horizontal shaft F, which is provided with a pulley G.
Figures 5 and 6 shew respectively a side elevation partly in section,
and also a plan of an arrangement for working a pump in a deep well,
according to our said Invention, and are drawn to a scale of one inch 2
to a foot. A is a vertical shaft provided with a disc B working on
friction rollers C,. C, which said friction rollers carry the weight or
part thereof of the said vertical shaft A; D acts as a side bearing for
the vertical shaft A, and also as a support for the friction rollers C, C.
At the lower extremity of the vertical shaft A is fixed a disc E having 3
a crank pin F; G is the pump and is worked from the said crank pin F
by means of the connecting rod H.
It is evident that various modifications of these arrangements may
be made and will be clearly understood without the aid of additional
Drawings.
i
The portable pump illustrated by Figures 1 and 2 may be worked by
hand or other power, excepting animal power (in distinction from human)
by applying an arrangement similar to that illustrated in Figures 3-

page_text: and 4 instead of the horse shafts G, G. If worked by hand a handle
would be fixed to the horizontal shaft F and the proportions of the bevel
wheels arranged to give the necessary leverage.
This arrangement may also be used to work the well pump by hand.
If it is desired to work the well pump by horse or other animal power
excepting human power, horse or other shafts may be used similar to
that shewn in Figures 1 and 2. For shallow wells friction rollers aro
not required to carry the weight of the vertical shaft, but the shaft is
carried by a collar or other suitable appliance. For deep wells friction
rollers must be used either at top or bottom, or both, an also at an
intermediate point or points, if the depth is considerable. In the latter
case the upright or vertical shaft would have to be in lengths coupled
together. A return crank may be used at the bottom of the vertical
shafting, and the bottom journal work in a step instead of or auxiliary
to bottom friction rollers, or instead of or auxiliary to a collar at the
top.
Having now particularly described and ascertained our said Invention
and in what manner the same may be performed, we declare that wo
claim the vertical shafts A, shewn on the Drawings, working in con-
junction with the levers, wheels, and pumps, as described and shewn on
the Drawings; and as various modifications follow obviously from the
description of this Invention, we declare that we do not limit ourselves
to the exact arrangements as shewn, but claim such arrangements and
modifications as are in harmony with the general description of our
Invention.
In witness whereof, I, the said Joseph Evans, on behalf of myself,
and the said William Evans, have hereunto set my hand and
seal, this Eleventh day of December, in the year of our Lord
One thousand eight hundred and seventy-one.
