Improvements in Wind Engines or Motors and Pumps to be Used
with the same.
We GEORGE GORDON PICKING and WILLIAM HOPKINS both of 58 Bow Road in
the County of Middlesex Engineers do hereby declare the nature of this invention
to be as follows :-
Our Invention relates to wind engines or motors that is to say engines developing
the force obtained from the wind for pumping and other purposes.
The object of these improvements is to simplify and increase the efficacy and
durability of this class of motor.
These improvements consist of the employment of several novel devices and arrange-
ments as applied to wind engines as follows.
Constructing the sails or vanes of the wind wheel or head of thin corrugated metal
whereby great rigidity of construction combined with minimum weight is obtained.
The simple arrangement of attaching the metal sails or vanes to the arms of the
mill head by small eye bolts passing through the wooden arms.
The sails or vanes are kept to the wind by means of a double chain and weight
attached the chain passing over pulleys fitted in suitable brackets on the mill head
and the chain being attached to a lever which controls a clutch working on the main
shaft all the vanes or sails are held to the wind automatically by the weight on the
chain but in the event of excessive wind or gales the pressure on the vanes or sails
turns them (the vanes or sails) edgewise to the wind and by so doing raises or
lowers the clutch lever and also the weight on the chain the wind thus passes
through the mill head without damaging it in anyway. As soon as the pressure of
wind is reduced the weight on the chain falls and automatically again places the
sails or vanes in position for work.
The rotary wheel tail of the mill is also made of corrugated metal and turns the
mill head round to the direct force of the wind automatically by a worm working
in a worm wheel attached to the supports of the wind engine.
Also wind engines with flat tails we make of corrugated metal.

page_text: The supports of the wind engine are of wrought iron and consist of angle or tee
iron uprights with cross bracing of flat iron.
The pumps for the discharge of the water driven by these motors are of very
special and simple construction being double acting vertical action with large passages
for the free course of the water and consist of a pair of suction valves on the base
plate and a pair of delivery valves on the top plate held together by bolts passing
through both plates the working barrel piece keeping them apart the required
distance to suit the stroke of the pump.

Improvements in Wind Engines or Motors and Pumps to be Used
with the same.
We GEORGE GORDON PICKING and WILLIAM HOPKINS, both of 58 Bow Road,
Bow, in the County of Middlesex, Engineers, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our invention relates to wind engines or motors, that is to say, engines developing
the force obtained from the wind for pumping and other purposes. The object of
these improvements is to simplify and increase the efficacy and durability of this
class of motor.
These improvements consist of the employment of several novel devices and
arrangements as applied to wind engines as follows:-Constructing the sails or
vanes of the wind wheel or head of thin corrugated metal whereby great rigidity of
construction, combined with minimum weight is obtained.
The simple arrangement of attaching the metal sails or vanes to the arms of the mill
head by small eye bolts passing through the arms. The sails or vanes are kept to
the wind by means of a double chain and weight attached, the chain passing over
pulleys fitted in suitable brackets on the mill head and the chain being attached to a
lever which controls a clutch working on the main shaft, all the sails or vanes are
held to the wind automatically by the weight on the chain, but in the event of exces-
sive wind or gales, the pressure on the vanes or sails turns them (the vanes or sails)
edgewise to the wind, and by so doing raises or lowers the clutch lever and also the
weight on the chain, the wind thus passes through the mill head without damaging it
in any way.
As soon as the pressure of the wind is reduced the weight on the
chain falls and thus automatically again places the vanes or sails in position for work.
The rotary wheel tail of the mill is also made of corrugated metal and it turns the
mill head round to the direct force of the wind automatically by a worm working in
a worm wheel attached to the supports of the wind engine.
We also make wind engines with flat tails of corrugated metal.
The supports of the wind engine are of wrought iron and consist of angle or tee iron
uprights with cross bracing of flat iron.
The pumps for the discharge of the water, driven by those motors are of very special
and simple construction being double acting vertical action with large passages for the
free course of the water and consist of a pair of suction valves on the base plate, and
a pair of delivery valves on the top plate held together by bolts passing through both
plates, the working barrel piece keeping them apart the required distance to suit the
stroke of the pump.
Referring to the drawings:
Fig. 1 is a side view of a mill head and pump constructed acccording to this inven-
tion. A. A. are the thin corrugated sails or vanes which are rivetted or otherwise

D D The motel caile ore attached somewhat ont

page_text: of the centre line of the bars so that the force of the wind will open them and turn
them edgewise to the wind. The bars are arranged to turn in sockets at each end of
the arms of mill head.
Figs. 2 and 3 are enlarged views shewing the arrangement for turning the sails, the
eye bolt C, being shown in Fig. 3. This eye bolt is attached to the arm at about
the middle to assist in keeping the sail or vane from bulging out by a back wind.
The levers D are securely attached to the bar which passes up the back of the sail
and serves to keep the sail in the proper angle as set.
The rocking levers E work in the sliding clutch piece F, which clutch piece is
governed by the lever G, an endless chain is attached to the end of the lever G and
passing over two pulleys in standard H, and also over two pulleys in bracket I, is led
down to near the ground level and is passed through a pulley bracket J, upon which
are weights which serve to keep the sails or vanes to the wind in the position in
which they are set by any person pulling one side or the other of the endless chain at J.
In the pulley bracket J there is a small screw K which tightens the chain to the
pulley bracket J, so that when so tightened, should the sails or vanes be turned by
excessive wind the weight L is raised, and as soon as the pressure of wind is reduced
the weight falls and so sets the sails in position for work.
The arms of the mill head are dished, and braced together by flat iron braces L'
round outer ends, thus making the whole very rigid.
Fig. 1 shows a wind engine working a pump by means of an ordinary crank
plate and coupling on to the pump rod, but where rotary motion is required a pair
of wheels is used as shewn in Fig. 4.
Fig. 5 shews a flat tail of a wind engine made of thin corrugated metal.
Fig. 6 is a part front view of mill head.
Fig. 7 is a section of the vertical double acting pump worked by the wind
engine.
M is the suction inlet for the water; N is the delivery outlet for the water; O
is the air vessel formed in the top plate; P, P, are the two suction valves;
R, R, are the two delivery valves.
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. In wind engines or motors the use of vanes or sails made of thin corrugated
metal, substantially as and for the purpose set forth.
2. In wind engines or motors the arrangement of vanes or sails, also the means of
turning and regulating the same, substantially as shewn and described.
3. In wind engines or motors constructing rotary or flat tails of thin corrugated
metal as described.
4. The arrangement of top and bottom chamber with barrel piece, suction and
delivery valves, in pumps for wind motor engines substantially as shewn and
described.
