JOHN EDWARD ROGERS of Poplar Street Smethwick in the County of Stafford,
Engineer do hereby declare the nature of this invention to be as follows
Improvements in actuating gear for Pumps.
-
Two stands or frame sides of the ordinary pattern are bored out to receive crank
shaft, gear spindle, and motion bars.
The gear or driving spindle carries two pinions to gear in spur wheels, keyed on
crank shaft.
The driving shaft pinions are either connected, or cast together, and made to slide
on their shaft in and out of gear, with the spur wheels on crank shaft, so that in the
working of the frame arrangements they are thereby made for driving the crank
shaft at two speeds-From the crank shaft or throw bearing is coupled the usual end of
connecting rods. This end is carried down the required distance on the frame, and
the other end is arranged to fit between side plates in their centre.
These side plate
ends take in, ordinary radius rods of parallel motion on either side of frame. The
end of the said radius rods pivots on the motion bars.
This frame may be arranged without gearing, or with one or moro throw cranks
and may be otherwise modified without departing from the nature of my said
invention.
Another arrangement or modification of my improvements, is ;-
Between the ordinary two stands or frame sides, I arrange a balance lever working
on a central pivot, at the top of the said two stands or frame sides. At the requisite
distance from the centre of balance lever,. I have two connecting rods carried
downwards, and jointed on two radius rods pivotted at the outsides of the feet of the
said stands or frame sides with their ends projecting inwards a sufficient distance so
that the ends come together at the distance of the centre of the barrels of the two
pumps.

page_text: The connecting rods may be moved along the balance lever, and bottom radius rods
to give a different stroke to the pumps.
This frame may be modified without departing from the nature of my said invention.

JOHN EDWARD ROGERS Sycamore Road (late of Poplar Street) Smethwick, in the
County of Stafford, 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 1
in and by the following statement :-
Sheet 1. Figures 1, 2 and 3 shew end and front elevations and section of Pinion
Shaft of a Frame constructed according to my Invention.
Like letters mark like parts in each Figure A A are the main side Frames bored
out to receive the various parts of the gear.
B B are Fly Wheels keyed on Pinion Shaft J on which are free to slide the
connected Pinions D and D¹ in and out of gear with their respective Spur Wheels C
and C keyed fast on the Crank Shaft E. This crank Shaft E through the con-
necting rod F gives a parallel motion to the Pump rods M M. The parallel motion
of the Pump rods M M is obtained by means of the radius rods H working on pivot
shaft I working inside links G.
Thus it will be seen that the frame is geared to work at two speeds and give a
parallel motion to the Pump rods when worked by the operators at handles N N fixed
in Fly Wheels B B.
Sheet 2, Figures 1 and 2 shew another design of Deep Well Pump Frame con-
structed according to my Invention.
Figure 1 is side elevation and Figure 2 end view.
Like letters mark like parts in each Figure.
A A are main side Frames, B is centre part of main Balance lever pivoted on pin H
in Main Frame. CC are moveable parts of balance lever B with handles J J. fixed in
ends for the purpose of operating the frame. D D are extra lengths for lengthening
the Balance lever B by attaching at joints M M, of balance lever B and C C.
E E are connecting Rods for communicating movement to levers F F, working on
Pivots I I which in turn give motion to well Rods G G.

page_text: K K K K in Main Balance lever B and L L L L in pivot lever F F, are holes
into which the connecting rods E E may be changed for the purpose of giving power
in working the frame.
Thus it will be seen that when the Main lever B is operating with an up and down
or sce-saw movement, motion is communicated to the Well Rods G G through the
various parts before mentioned and shewn in drawings.
Having now described my Invention as shewn in accompanying drawings, what I
claim is.
1. In deep Well Frames as shewn on Sheet 1, Figures 1, 2 and 3.
The changeable Gear C-C and D-D₁ in combination with Crank E and shaft J.
2. The combination of the connecting rod F, with side links G and radius rods H
working as shown and described.

necting rods E E. Pivot levors F F. with their respective adjusting holes K K K K.
