page_text: I, EDWARD GRIFFITH BREWER of 33 Chancery Lane in the County of Middlesex
Fel. Inst. P.A. do hereby declare the nature of this invention (a communication
to me from abroad by Theodor Schulze, Watchmaker and Sylvester Görnicki,
Merchant, both of Berlin Germany) and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:"
This invention refers to a wind or water motor of simple construction and
whereby high power is obtained. It is a class of motor suitable to be acted upon
by wind as well as water, and the invention will be best understood by reference
to the accompanying drawings.
Figure 1 shews a motor in ground plan constructed according to this invention.
Figure 2 is a vertical section through the lower part, and Figure 3 shews. the whole
arrangement of the wind wheel. Figures 45 and 6 are detail views.
The motor consists of several floats or wings a free to turn upon vertical axes;
the axes of these floats are fixed both at top and bottom to tie rings d which by
arms or spokes e are connected to a boss fitted upon a vertical shaft A
The floats a are free to turn upon their axes between the rings d. In order
however that the floats a may oppose a flat surface to the wind, there are placed
on the inner and outer sides of the rings d other rings f f¹ upon which are
arranged stops g and g¹ against which stops the free ends of the floats a strike
when driven by the wind.
The position of these stops g and g¹ is so measured that each stop forms an
angle of say 90° with the axes b of the floats. The result is that the floats a take
against the stops g g¹.
When the wind is in the direction of the arrow x (Figure 1) from the front to
the back the floats assume the position sbewn. The front ones (to the left) of the
shaft A lie some against the inner stop g and some are in the 'direction of the wind,
and the back (or right) floats lie some against the outer stops g₁ and some also in
the direction of the wind. In this way the greater number of the floats are at
work, only a few being not in action.
An opposite action of the floats cannot take place, because those floats not lying
close against the stops are always in the direction of the wind.
When the wind wheel is overloaded say by a storm, or it is at other times
desired to keep same still, nothing else is necessary than to bring the stops g and g'

page_text: out of the reach of their respective floats a when the floats will then assume a
position in the direction of the wind.
The taking out of the stops is accomplished as follows:
The stops g g turn on pins h¹ in the rings f f¹ and are maintained in their
normal position by means of springs i Figure 4. They project with their upper
end above the surface of the rings.
Every two stops g gl are, as shewn in Figure 2 connected with one another by a
rod h so that by a pull in the direction of the arrows a Figure 2 both stops g
and g turn about together, and their upper ends no longer project above the upper
surface of the rings ƒ ƒ¹.
The pull released the stops reassume by the action of the springs i Figures 4
and 5, their normal position.
The falling down of the stop is occasioned by a pull on the wire, chain or rope k
fastened to ġ and passing over a pulley Figure 6 fixed on shaft A
The wire, chain or rope k is caught upon the pin upon shaft A and.is left
there so long as its float is not required to work, the float then being free.
In this way each couple of stops may be brought away from contact with the
floats a.
To set the wheel in motion again the stops gg' must be brought to their first
position, and the floats be brought to their position between the stops g g¹. The
former is done by simply unhooking the wire, chain or rope from the pin k³ and the
latter is effected as follows:-
On the spokes of the lower ring d is placed a toothed wheel m loose upon the
shaft A and which can turn independently of d. This wheel m has an arm m² on
the end of which is a pulley m². Said wheel m is geared into a small spur wheel n
fitted on shaft n' and which can be turned through toothed wheel n by means of
the crank n³, Figure 3. The shaft n' is fitted in an arm on shaft A.
It follows that by this arrangement the wheel m can be turned together
with the wind wheel, and it can besides be turned in either direction from the
crank n³.
L
The wind wheel is now in a position of inaction together with the floats which
are in the direction of the wind, and the arm m¹ of the wheel m in the position
shewn in Figure 1. The wheel m is, or may be, turned, by means of the crank m³
in the direction of the arrows y Figure 1, which thereby causes the arm m¹ with
pulley m to take hold of the nearest float, and to press it against the flat surface
of the stop g and finally it is forced on to the edge of the stop, and passes itself
over it, and then between g and g¹. By further turning, the arm m! takes hold of
the next float and places that between the stops, and so on.
To adapt the wheel as a water motor the stops and drawing out arrangement are
brought over the upper part of the wheel.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim as the invention communicated to me is:-
A new or improved wind or water motor having several floats working from
centres at equal distances apart with their axes vertical, and situate between stops
placed at an angle with each float, substantially as herein set forth.
