PROVISIONAL SPECIFICATION.
Improvements in Wind-wheels.
I, Carl ReinscH, of 14, Freiberger Strasse, Dresden, Saxony; in the Empire of
Germany, Machine Manufacturer, do hereby declare the nature of my said inven-
tion to be as follows:-
The object of my invention is to effect improvements in the construction of wind
wheels, whereby the angle of the vanes may be automatically regulated, according
to the force of the wind and the required speed of revolution.
The wheel consists principally of two concentric iron rings of suitable diameters,
supporting a number of pivoted vanes in the concentric space between the rings.
The rings are supported by radial arms in the usual manner, the whole being
mounted on an axle revolving in bearings, and capable of being turned in the
direction of the wind by a wind vane fixed to a shaft, in a line with the axis of the
wheel. On two, three, or more of the radial arms, fit a pair of parallel levers,
linked together at their outer ends by a connecting rod. The lever nearest the
centre of the wheel is fitted with a connecting rod, leading to a bell crank near the
centre of the wheel. These bell-cranks are connected to a sliding sheave on
the axle, in such a manner that, on the sheave being drawn forward by the bell
cranks, one, two, or more weighted lever or levers is or are raised; and vice versa.
The connecting rods attached to the levers on the radial arms are fitted with weights,
in such a position, radially, that a too-rapid rotation of the wheel, causes the weights
to move radially by centrifugal force. This outward motion is caused to act upon
the vanes, by suitable links, in such a manner as to increase their angle relatively to
the wind, and thus regulate the speed of rotation of the wind-wheel.
The whole set of vanes are connected together by a circular band or rod, so as
to reef them all simultaneously.
Suitable connections are also arranged for regulating the set of the vanes by
hand.

Improvements in Wind-wheels.
1, CARL REINSCH, of 14 Freiberger Strasse, Dresden, Saxony, in the Empire
of Germany, Machine Manufacturer, do hereby declare the nature of my said inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of my invention is to effect improvements in the construction of wind
wheels, whereby the angle of the vanes may be automatically regulated, according
to the force of the wind and the required speed of revolution.
The wheel consists principally of two concentric iron rings of suitable diameters,
supporting a number of pivoted vanes in the concentric space between the rings.
The rings are supported by radial arms in the usual manner, the whole being
mounted on an axle revolving in bearings, and capable of being turned in the
direction of the wind by a wind vane fixed to a shaft, in a line with the axis of the
wheel. On two, three, or more of the radial arms, I fit a pair of parallel levers,

centre of the wheel is fitted with a connecting rod, leading to a bell crank near
the centre of the wheel. These bell-cranks are connected to a grooved sliding
sheave or pulley on the axle, in such a manner that, on the pulley being drawn
forward by the bell cranks, one, two, or more weighted lever or levers is or are
raised; and vice versa. The connecting rods attached to the levers on the radial
arms are fitted with weights, in such a position, radially, that a too-rapid rotation
of the wheel, causes the weights to move radially by centrifugal force. This
outward motion is caused to act upon the vanes, by suitable links, in such a manner
as to increase their angle relatively to the wind, and thus regulate the speed of
rotation of the wind-wheel.
The whole set of vanes are connected together by a circular band or rod, so as to
reef them all simultaneously.
Suitable connections are also arranged for regulating the set of the vanes by
hand.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar figures of
reference indicate corresponding parts.
Fig. 1 is a front elevation of my improved wind-wheel, and Fig. 2 is a side
elevation some portions being omitted for greater clearness.
1 is the outer concentric hoop or ring. 2 is the inner ring. 3, 3, are radial arms,
attached to the axle 4 in the usual manner, (the hub being omitted in Fig. 1).
5, 5, 5, are three of the vanes, pivoted to the hoop or ring 1 at 6, and to the
ring 2 at 7.
8 is a circular ring pivoted to one edge of each of the vanes. 9, 10, are two
parallel levers; the lever 9 being pivoted to the ring 1 at 11; and the lever 10
being pivoted to the radial arm 3 at 12. 13 is a connecting rod, pivoted to the
outer ends of the levers 9, 10. This rod 13 is loaded with an adjustable weight 14.
The lever 10 carries an arm 15, which is connected with the ring 8 by means of
two pivoted links 16, 17. 18 is a rod pivoted to the lever 10 at 19, and to the bell
crank lever 20 at 21.
22 is a grooved sheave or pulley rotating with the axle 4, but capable of sliding
thereon, longitudinally. 23 is a link pivoted to the bell crank lever 20 and to the
pulley 22.
35 is
24, 24, are parts of the stationary framing supporting the apparatus. 25 is an
annular bearing, to which the support 26 is fitted so as to turn in any direction
horizontally, supporting the bearings for the axle. The support or tablet 26 also
carries a bracket 27 and a rod 28 and vane 29 for keeping the wheel square to the
wind. 30 is a vertical shaft, connected with the axle 4 by bevel gear 31 for con-
veying the power to any convenient mechanism, where required. 32 is a lever'
pivoted to the bracket 27 and carrying a forked lever 33, the fork working in the
groove of the pulley 22. 34 is an adjustable weight fitted to the lever 32.
an additional lever, carrying an adjustable weight 36, the lever being pivoted to the
vertical strut 38 and united to 32 by the rod 39. 37 is a rope, chain, or rod, by
means of which the levers 32 and 35 can be raised, as shown in Fig. 2. The
raising of these levers causes the pulley 22 to recede from the wheel, thereby
raising the weight 14 and rod 13, and placing all the vanes 5, 5, more or less at an
acute angle, or entirely out of action, by turning their front edges to the wind, as
required.
When the wheel is being driven by the wind, (the rope 37 being free) the angle
of incidence of the vanes 5, 5, is automatically governed by the weights 14,
levers 9, 10, 32, and 35, and their connections. An increase of rotative velocity
causes the weights 14 to recede from the centre by centrifugal force, whereby the
pitch of the vanes is increased; and vice versa. The outward motion of the
weights 14 raises the weighted levers 32, 35; and these levers, by their connections,
restore the vanes 5, 5, to a finer pitch when the velocity is reduced.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved method of automatically controlling and regulating the speed
of revolution of a wind-wheel, by means of weighted levers, so arranged that the
pitch of the vanes 5, 5, is increased or reduced, substantially as herein before
described and illustrated by the drawings.
2. The general construction, arrangement and combination of mechanism, and
the several and respective parts thereof, together forming my invention of improve-
ments in wind-wheels, substantially as herein before described and illustrated by
the drawings.
