Improvements in Apparatus for Operating Deep Well Pumps.
WILLIAM ALLMAN 45 Villa Road Handsworth in the County of Staffordshire
Manufacturer and JOHN MILLWARD 36 Temple Street Birmingham in the
County of Warwick Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to new or improved devices for operating pumps in deep
wells, mines, or other similar positions which in addition of being applicable to
ordinary lift and force pumps are also applicable for working plunger pumps
without heavy and complicated rods and adjuncts.
In pumping apparatus constructed in accordance with this invention the driving
gear situated at the top of the well may be of any usual construction for animal,
steam, or other power but instead of the ordinary two, three, or four throw cranks
the pumping shaft has a single crank either bend or disc.
At some short distance below the pumping shaft or in case of overhead driving
gear at the ground floor level is mounted on suitable carriers a double ended lever
or short beam to operate two or more pumps by the devices afterwards described.
On the same spindle as the beam is an arın with slotted end with adjustable pin to
vary the stroke if preferred which is operated by a connecting rod from the crank
on the pumping shaft.
The pumps whether plunger or lift pumps are mounted on a frame or girder in a
suitable position near the bottom of the well. At a short distance above the
pumps is mounted on a separate frame or girder or on a stand bolted to the pump
frame a pulley with rim grooved to carry a steel wire or other rope and of about
the same diameter as the length of the beam. A steel wire or other rope is passed
under this pulley and carried up the well to the said beam at the top at any height
and connected or attached to joint pins at each end of the beam mounted with
adjusting or stretching screws or instead of the beam a similar pulley to that at the
bottom may be used with suitable grips for the steel wire or other rope.
The wire rope near the pulley at the bottom is furnished with suitable grips
which are connected with short rigid links to the pump plunger or rods.
It will be readily understood that upon operating the pumping shaft at the
surface the beam shortly below it is vibrated and a reciprocating motion is given
the wire rope on each side and communicated by the means described to the pumps
at the bottom whether plunger or lift pumps and at the same time the wire rope is
always in tension.
As a modification in accordance with this invention, instead of the pulley at
the bottom a short beam similar to that at the top of well is mounted near the
pumps and connected with light steel or other rods to the said top beam and the
only strain upon the rods will be tensional as before.
The beams or pulleys may be duplicated on the same spindles so as to operate
four or more pumps if required.
In accordance with this invention also pumps may be operated in a horizontal or
inclined or other position in driftways or levels at some distance from the well or
shaft by conducting the wire rope or other connections round suitable guide pullies
or levers.
In accordance with this invention also the frames or girders carrying the pumps are
constructed with openings for the pumps to be easily placed in position sideways and

a whole.

Improvements in Apparatus for Operating Deep Well Pumps.
We, WILLIAM ALLMAN, of 45 Villa Road, Handsworth in the County of
Stafford, Manufacturer, and JOHN MILLWARD, of 36 Temple Street, in the City
of Birmingham, 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:-
This invention relates to improvements in apparatus for operating pumps in deep
wells, mines, or other positions away from the driving gear or mechanism.
The object of our invention is to enable such pumps to be readily fixed and to
be worked without the employment of the heavy and complicated rods and adjuncts
necessary with the ordinary methods of operating at present in general use.
In the two accompanying sheets of explanatory drawings to be hereinafter
referred to
Figure 1 Sheet 1 is an elevation representing a pair of deep well pumps arranged
in accordance with our invention.
Figure 2 Sheet 2 is an elevation representing a modified arrangement of the
driving gear or mechanism.
Figure 3 is a plan of the driving gear shown in elevation at Figure 1.
Figure is a plan of our improved girder or carrier frame to which the pumps
are fixed.
In the application of our invention we employ any convenient or suitable form
of driving gear, for animal, steam, or other available power. In the arrangements
of driving gear illustrated as fixed above the mouth of the well A in Figures 1
and 2, the necessary power is transmitted preferably by means of the belt B.
Beneath the driving gear we fix a shaft such as C which has a rocking motion
imparted to it by means of the connecting rod D attached at its upper end to a
crank forming part of the driving gear, and at its lower end to a slotted arm
secured to the shaft C. Upon the rocking shaft C we fix the double ended lever
or short beam E for the purpose of operating the two or more pumps in the manner
hereinafter described.
The plunger or other type pumps F are mounted upon the girder or carrier
frame G which is fixed in a suitable position near to the bottom of the well. At a
short distance above the pumps we mount, upon suitable standards such as H
bolted to the girder G, or upon a separate and independent frame or girder, a
pulley J with grooved rim suitable for a steel wire or other rope K which is passed
under the pulley. The ends of the rope K are connected to the ends of the
beam E, suitable stretching screws or other adjusting appliances being provided to
take up any slackness of the rope. Near the pulley J we provide suitable grips or
attachments L for securing the upper ends of the pump plunger or continuation
rods M.
When the driving gear is set in motion by the power transmitting belt B, or by
other means, the beam E is vibrated and a reciprocating motion is imparted to the
rope secured to its ends, and to the attached plunger reds M.
In this manner we are enabled to operate the pumps F with the rope K constantly
in tension, thus dispensing with the use of heavy and cumbersome pump rods
necessary with the ordinary methods of working.

page_text: Instead of the beam E upon the working shaft C we sometimes employ a pulley
such as E Figure 2, providing grips when necessary for the purpose of preventing
any slipping of the rope; or instead of the pulley J we sometimes employ a short
beam or double ended lever such as E.
When employing a wheel or pulley such as E' we can dispense with the use of
an independent slotted arm or crank on the rocking shaft C, by forming a slot such
as e in one of the wheel arms as illustrated at Figure 2.
We sometimes employ light steel or other tension rods instead of the rope K..
attaching them both at the upper and lower ends to the extremities of short beams
or double ended levers such as E.
We construct the pump supporting girder or carrier frame G with side openings.
such as N Figure 4 which permit of the pumps being fitted up completely on the
surface and then to be readily lowered and slipped sideways into position upon the
frame, and in like manner to be removed when required without dismantling or
taking to pieces.
Two or more beams or pulleys are employed on the same or separate shafts or
spindles when necessary for the purpose of operating the required number of
pumps, and they are arranged with suitable driving gear or mechanism for
operation in a horizontal, inclined, or other position, and in driftways or levels at
some distance from the well or shaft, the wire rope or other connection being
conducted and supported by suitable guide pulleys or other supports.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1. The improved method of operating pumps by means of a steel wire or other
rope or by tension rods substantially as herein described.
2. The combination of a rope or tension rods with rocking beams or pulleys
substantially as and for the purposes hereinbefore described and as illustrated in
the accompanying drawings.
3. In combination with the rope or tension rods and the rocking beams or
pulleys, the pump plunger or continuation rods attached directly to such rope or
rods substantially as and for the purposes hereinbefore described and as illustrated
in the accompanying drawings.
4. The construction of a supporting girder or carrier frame for deep well pumps
having side openings substantially as and for the purposes herein before described
and as illustrated in the accompanying drawings.
5. The improved general combination and arrangement of the pump operating
appliances substantially as and for the purposes herein described.
