PROVISIONAL SPECIFICATION.
Improved Apparatus and Means for Producing Reciprocating from
Circular Motion, suitable for Pumps and other like Actioned
Machinery.
We ERNEST WILLIAM BEECH of 11 The Pavement, Wanstead, Essex, Builder
and WILLIAM GEORGE GILLINGHAM of, Frinton on Sea, Essex, Auctioneer do
hereby declare the nature of this invention to be as follows:
:-
This invention has for object the obtaining of power with less than usual
labour when working pumps in which plungers have reciprocating action.
For the purpose of this invention we employ wheels and chains which have a
continuous travel in one direction and produce a reciprocating of the plunger rod
through a frame provided with teeth into which the chain link pins can engage in
alternate order. The pins may be as loops between the wheels or extend from the
outside or the chains may drive other wheels or half wheels for engaging in the
teeth of the plunger rod frame.
As an example of this invention we arrange say a couple of toothed or sprocket
wheels in a box or casing at a distance apart and mount a chain to run on them,
said chain joint pins or projections therefrom being within range of teeth on the
inner faces of hars forming part of a frame attached to or part of the plunger rod
the teeth being at different elevations on opposite bars so that the link pins take
into one set of teeth in the uprising motion and into the other for the descending
motion.
We prefer that the sets of wheels be of different diameters for power or for speed
and according to the number of link pins set for operation in the length of chain so
the length of stroke of the plunger can be regulated.
If half wheels or mutilated toothed wheels be employed to operate the plunger
rod the chain could be the driver from the same or from an additional axle.

COMPLETE SPECIFICATION.
Improved Apparatus and Means for Producing Reciprocating from
Circular Motion, suitable for Pumps and other like Actioned
Machinery.
We, ERNEST WILLIAM BEECH, of 11 The Pavement, Wanstead, Essex, Builder,
and WILLIAM GEORGE GILLINGHAM, of Frinton on Sea, Essex, Auctioneer,
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 has for object, the obtaining of power with less than usual labour
when working pumps, or other like actioned machinery in which plungers have
reciprocating action.
For the purpose of our invention, we employ wheels and chains which have a
continuous travel in one direction, and produce a reciprocating of the plunger rod
through a frame provided with teeth into which the chain link pins can engage in

page_text: alternate order. The pins may be as loops between the wheels, or extend from the
outside, or the chains may drive other wheels, or half wheels for engaging in the
teeth of the plunger rod frame.
As an example of our invention, we arrange say a couple of toothed, or sprocket
wheels in a box, or casing at a distance apart, and mount a chain to run on them,
said chain, or joint pins, or projections therefrom being within range of teeth on the
inner faces of bars forming part of a frame attached to or part of the plunger rod,
the teeth being at different elevations on opposite bars, so that the link pins take
into one set of teeth in the uprising or forward motion and into the other for the
descending or return motion.
If half wheels or mutilated toothed wheels be employed to operate the plunger
rod, the chain could be the driver from the same, or from an additional axle.
The invention is shown in the annexed drawings.
Figure 1 a side elevation.
Figure 2 a section through the line a, b, Figure 1, of an apparatus.
A is a bed plate supporting a girder C by pillars B, B. The upper rib D of the
bed and the lower rib E of the girder C serving as guides for the reciprocating
motion of travelling blocks or slides F, F, which are connected by two rods G, G,
to the crosshead H of the pump, or other machinery to which a to and fro motion
is to be given.
The bed A also supports pedestals I, I, in which crank axles J, J, are mounted,
and one of said axles has a sprocket wheel K, the other having a pinion L to gear
into another pinion M on the axle P on which another sprocket wheel is mounted.
The two sprocket wheels are linked by a chain Qon which are two pius or arms R, R,
which engage alternately in teeth S, S, of plates projecting from the slides R, R,
between which the chain slides as shown in Figure 2, so that when the crank
handles T, T, are turned, the chain Q is drawn round by the sprocket wheels and
produce a reciprocating motion of the crosshead H, and pump rod U by the
pins R, R, taking into the teeth S, S, of the slides F, F.
V, V, are sprocket wheels arranged between the chain Q to hold them and
prevent them sagging, they also prevent the pins or arms R, R. dropping out of the
teeth S, S, of the slide F. Instead of said sprocket wheels, block Z, as in Figure 4,
may be used for the same purpose.
Figure 3 is a plan view of a modification in which a connecting rod W is affixed
to the crosshead H of the pump rod U, the opposite end or shank of said rod W
being connected to pins or arms R, R, of chains Q, Q, there being a clearance
between them for the free motion of the shank in its to and fro action at different
angles due to the diameter of the sprocket wheels, or the distance the upper and
lower chain links are from each other.
In Figure 1, the chains are driven direct from one crank axle but in Figure 3,
they are driven through pinions L, M, of the cranks T, as will be understood by
the part sectional elevation, Figure 4. The pins or arms R, R, of this latter
arrangement are in a block or gudgeon X which has free movement in the shank
for the adjustment of the pins, as indicated more particularly by the dotted lines in
Fiureg 5.
According to the views Figures 6, 7, 8, 9 and 10, we employ wheels a with teeth bon
one half of the periphery in one plane, and with teeth C on the other half of the
periphery in another plane. Any number of these sets of teeth in pairs can be
arranged upon the same boss but not necessarily of the same diameter, as shown
more particularly in Figure 10, to engage in teeth of racks similarly formed and
attached to the pump rod U and sliding in bearings for the necessary reciprocating
action. The racks d are arranged with half the number of teeth 6 corre-
sponding to teeth on one side, or next one edge, the other half teeth c¹ on the
opposite side next the other edge, and any number of these racks can be arranged
according to the sets of teeth there are upon the driving wheel which are turned on
their axles by any convenient means, such as by crank handles, as in Figures 1, 2,
3, and 4, or by the chains thereof.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improved means and apparatus for producing reciprocating from
circular motion, as described with reference to Figures 1 and 2 of the annexed
drawings.
2. The improved means and apparatus for producing reciprocating from
circular motion as described with reference to Figures 3, 4, and 5 of the annexed
drawings.
3. The improved means and apparatus for producing reciprocating from
circular motion, as described with reference to Figures 6, 7, 8, 9, and 10 of the
annexed drawings.
