Improvements in Wind Motors.
I, WILLIAM JOSEPH STARKEY BARBER-STARKEY of Aldenham Park,
Bridgenorth, in the County of Salop, Gentleman, do hereby declare the nature
of this invention to be as follows:-
This invention relates to a new or improved construction of wind motor which
is particularly adapted for driving dynamos for use in charging accumulators or
storage batteries, but which may also be usefully employed for other purposes.
The wind sails, which may be flat; but which are preferably cupped or concave,
are arranged on arms radiating from the sail shaft, which may be either horizonta!
or vertical. On the windward side of the sails, I arrange a quadrant wind shield
having its centre of curvature in the axis of the sail shaft by preference, or an
equivalent wind shield capable of protecting the sails which are travelling against
the direction of the wind, from its direct action.
When the sails are arranged upon a vertical sail shaft, the wind shield only will
require to be shifted with changes of wind, and this may be accomplished
automatically by means of a steering sail arranged to keep the shield up to the
wind.
When, on the other hand, the sails are mounted upon a horizontal sail shaft, the
wind shield and sail shaft are mounted in a suitable framing capable of rotation
upon a vertical axis, and the shield and sails are kept in face of the wind, by a
steering sail or sails. With this arrangement two sets of sails may be employed
with a space between them in which a driving pulley or wheel is keyed upon the
sail shaft. A dynamo may be arranged in the framing preferably with its centre
of gravity over the vertical axis and be driven direct from the driving wheel or
pulley. The dynamo will be covered to protect it from the weather, and its current
may be taken off by means of brushes or rubbing contacts from two insulated metal
collars upon the vertical axis, which are respectively connected with the opposite
poles of the dynamo.
If it be preferred to arrange the dynamo in a fixed position below or near
the wind motor, the motion of the sail shaft may be communicated to it by any
suitable gearing.

Improvements in Wind Motors.
1, WILLIAM JOSEPH STARKEY BARBER-STARKEY of Aldenham Park,
Bridgenorth, in the County of Salop, Gentleman, 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 a new or improved construction of wind motor which is
particularly adapted for driving dynamos for use in charging accumulators and
storage batteries, but which may also be usefully employed for other purposes.
The wind sails which may be flat, but which may preferably be cupped or
convex, are arranged on arms radiating from the sail shaft, which may be either
horizontal or vertical. On the windward side of the sails, I arrange a quadrant
wind shield having its centre of curvature about in the axis of the sail shaft by

page_text: preference, or an equivalent wind shield, capable of protecting those sails which are
travelling against the direction of the wind from its direct action. In some cases
it will be obvious that surrounding buildings trees and the like may be utilised as
the equivalent wind shield.
When the sails are arranged upon a vertical sail shaft, the wind shield only will
require to be shifted with changes of wind, and this may be accomplished
automatically by means of a steering sail arranged to keep the shield up to the
wind.
When, on the other hand, the sails are mounted upon a horizontal shaft and a
movable wind shield is used, the shield and shaft are mounted in a suitable framing
capable of rotation upon a vertical axis, and the shield and sails are kept up to the
wind by a steering sail or sails. The plane of the sails is thereby kept in the
direction of the wind.
With the horizontal shaft and vertical sail arrangement two sets of sails may be
employed with a space between them in which a driving wheel or pulley may be
keyed upon the shaft. A dynamo may be arranged in the framing, preferably with.
its centre of gravity over the vertical axis, and be driven direct from the driving.
wheel or pulley. The dynamo will be covered to protect it from the weather, and
its current may be taken off by means of rubbing contacts or brushes, from two
insulated metal collars on the vertical axis, which are respectively connected with
the opposite poles of the dynamo.
If it be preferred to arrange the dynamo in a fixed position below or near the
wind motor, the motion of the sail shaft may be communicated to it by any suitable
gearing..
The accompanying drawings diagrammatically illustrate in what manner I may
carry my invention into effect and are hereinafter referred to.
Similar letters of reference used in each of the figures denote similar parts.
Figures 1 and 2 illustrate front and side elevations respectively of a motor
having a horizontal shaft and a pair of sails.
Figures 3 and 4 shew in side elevation and plan, a motor with a vertical
:shaft.
A-A are the sails; B the steering gear; C the sail shaft; D the shield;
and F the framing.
With the horizontal shaft form of the motor, I prefer to use the two parallel
sets of sails AA' which may be of the cupped or anemometer form for small
motors, and flatter or perfectly flat for those of larger size, arranged with their
concavities in the direction of the wind in the upper part of their circuit, and with.
the known means for veering and furling the sails if required. The sails are kept
up to the wind by the usual or any convenient means. As shewn by the drawings,
the rotary steering sail has a worm or tangent screw on its spindle, gearing with
the worm wheel G on the inclined shaft H, the lower end of which is geared with a
wheel on the platform I, which carries the horizontal shaft J in its bearings K.
The shaft J is furnished with a worm J' engaging with a circular rack F¹ secured
to the framing F. The quadrant shield D may be fixed relatively to the sails, or
be adjustable as shewn. In the latter case, each of the shields may have a quadrant
rack L fixed upon its inner face into which gears the pinion M on the shaft N
which also carries the chain wheel O on which the pitch chain P is arranged. By
pulling upon the pitch chain, the front edge of the shield may be raised or lowered,
and this arrangement may to some extent be used in substitution for one for furling
and veering the sails.
°
The motion of the sail shaft may be transmitted to the mechanism to be driven
thereby by any suitable means, for example, by the mitre or bevel wheels Q Q¹ of
which is fixed upon the sail shaft and Q on the vertical shaft R, the lower end
of which has fixed upon it a bevel wheel S gearing with the pinion S' secured to a
counter shaft T. Upon the counter shaft is a pulley W from which is driven the
pulley V on the armature spindle of the dynamo U.
When the vertical shaft motor is employed I prefer to use a single set of sails A,

page_text: mounted upon the upper end of the shaft C, from which the power is taken by
known means. The quadrant shield is mounted to move around the sails with the
shaft as a centre, and its position is determined by the action of the wind on the
steering sail B.
In the case of large motors of this type, the vertical shaft C may
be produced upwards, and the shield may be connected with a collar or cap on the
upper end of the shaft by suitable guys or suspending wires. The collar or cap
will of course be arranged to move freely on the shaft.
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 1
claim is-
1. A wind motor consisting of one or two sets of sails mounted on a horizontal
shaft, the plane of the sails being parallel with the direction of the wind, and their
lower part or parts being shielded from the direct action of the wind, constructed
substantially as hereinbefore described with reference to the accompanying
drawings.
2. A wind motor consisting of a set of sails mounted upon a vertical shaft and
having the returning sails shielded from the direct action of the wind, constructed
and arranged substantially as hereinbefore described with reference to the
accompanying drawings.
