PROVISIONAL SPECIFICATION.
in Portable and Stationary Wind Engines for
Agricultural and other Purposes, and in the Gearing for the
same.
We JAMES ADAMS of 26 Gaywood Street, London Road, Engineer, and DAVID
RICHARD EVANS of 62 Coxon Place, Horsley Down Wool Comber, both in the
County of Surrey, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements on a former invention for which Letters
Patent were granted to James Adams dated 22nd August 1889 numbered 13229
for "Improvements in Portable and Stationary Wind Engines for Agricultural
Purposes and in the Gearing for the same," and the present improvements consist
in fixing on a level platform four or more iron frames placed in a circle and bolted
on to the said platform and in each of these frames is placed a metal ball with
gudgeons which work in bearings on each side of the iron frames.
Further, near the circumference of the round table referred to in the Speci-
fication of the aforesaid former Letters Patent we fix a concave ring the table
being turned over the said ring fitting on to the aforesaid balls so as to allow the
table to turn either way which is an important feature in this invention the table
can be made to turn upon rollers if preferred.
Through the centre of said table is fixed a bush having a shaft through it
(this shaft is referred to as K³ in the Specification of aforesaid Letters Patent) on
the top end of this shaft and just above the table is fixed a spur wheel and below
the table is fixed one large and three small bevil wheels one of said small bevil
wheels below the large one works a short length of shaft projecting just beyond
the side of the carriage having a small spur wheel fitted with a forked lever which
shifts this wheel in or out of gear in order to stop or start the engine.
The sails or vanes we make curved for better gathering the wind these vanes
overlap each other so that no wind can pass through without being utilized and
each vane is fitted with spring shutters to regulate the speed of the machinery
when all the arms are fitted they form a perfect wind screw which constitutes
the motive power and will work either way required. This wind screw works
direct between the aforesaid uprights and equally balanced upon two plummer
blocks, but if more power is required two wind motors can be used in the following
manuer.
A longer shaft to extend outside the four uprights having a wind motor at each
end thus making it a double wind engine as the wind acting upon the one would
pass through and act upon the other or a fly wheel of equal weight would be an
assistance.

Agricultural and other Purposes, and in the Gearing for the
same.
We JAMES ADAMS of 26 Gaywood Street, London Road, Engineer and DAVID
RICHARD EVANS of 62 Coxon Place, Horsley Down, Wool Comber both in the
County of Surrey, 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 on a former invention for which. Letters
Patent were granted to James Adams dated 22nd August 1889 numbered 13229
for "Improvements in Portable and Stationary Wind Engines for Agricultural
Purposes and in the Gearing for the same" and the present improvements consists
in fixing on a level platform four or more iron frames placed in a circle and bolted
on to the said platform and in each of these frames is placed a metal ball with
gudgeons which work in bearings on each side of the iron frames.
Further, near the circumference of the round table referred to in the Specification
of the aforesaid Letters Patent we fix a concave ring the table being turned over,
the said ring fitting on to the aforesaid balls so as to allow the table to turn either
way which is an important feature in this invention the table can be made to turn
upon rollers if preferred.
Through the centre of said table is fixed a bush having a shaft through it (this
shaft is referred to as K' in the Specification of aforesaid Letters Patent) on the
top end of this shaft and just above the table is fixed a spur wheel and below the
table is fixed one larger and three small bevel wheels one of said small bevel
wheels below the large one works a short length of shaft projecting just beyond
the side of the carriage having a small spur wheel fitted with a forked lever which
shifts this wheel in or out of gear in order to stop or start the wind engine. (This
forming part of the aforesaid Letters Patent.)
The sails or vanes we make curved for better gathering the wind these vanes
overlap each other so that no wind can pass through without being utilised and
each vane is fitted with spring shutters to regulate the speed of the machinery
when all the arms are fitted they form a perfect wind screw which constitutes
the motive power and will work either way required.
This wind screw works direct between the uprights (referred to in the aforesaid
Letters Patent) and equally balanced upon two plummer blocks, but if more
'power is required two wind motors can be used in the following manner.
A longer shaft to extend outside the four uprights having a wind motor at each
end thus making it a double wind engine as the wind acting upon the one would
pass through and act upon the other or a fly wheel of equal weight would be an
assistance.
And in order that our said invention may be better understood we will describe
the same with reference to the accompanying sheets of drawings in which,
Fig. 1 is plan of table shewing ball bearings.
Fig. 2 section of ball and table.
Fig. 3 plan of ball in frame.
Fig. 4 end view shewing double wind screw.
Fig. 5 shews front view of vane shewing spring. shutters.
Fig. 6 cross section of same.
Fig. 7 horizontal section shewing curvature of vanes.
Fig. 8 enlarged section of shutter and spring.
The same letters denote the same parts in all views:

page_text: a shews revolving table, b ball bearings for same fitting into ring b, c gudgeons
connected to said balls, d frame to carry the balls, e (dotted) shews the position of
fan for a single wind engine,ƒ and g fans for a double wind engine, h shutter i spring
for same, k main shaft bevel gearing working vertical shaft m the table is
worked by the worm n shewn on Fig. 1, described and shewn clearly in the
aforesaid former Letters Patent.
Although we have shewn a spiral spring for keeping the shutters closed until
the wind is too great we may of course use any other suitable spring arrangement
for this purpose.
We further have the vanes curved as shewn so as to gather the
wind better.
The action is as follows,
The wind passing through the fan g in a double wind engine Fig. 4 will be
utilized by the other fan f.
The shutters will act when the wind is too great and will be kept closed by
means of the spring i when the pressure if wind reduces thereby regulating the
speed of engine.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. Making stationary or portable wind engines with a double set of vanes on
one shaft.
2. In wind engines, the table working on ball bearings substantially as set
forth.
3. In wind engines, vanes having adjustable shutters substantially as and for
the purpose set forth.
4. In wind engines vanes' formed curved.
5. Wind engines constructed substantially as set forth.
