Improvements in Wind Mills or Wind Engines.
I, IRA ALLEN JEFFERSON of Park City in the County of Summit and
Territory of Utah, United States of America, Carpenter, do hereby declare the
nature of this invention to be as follows:-
-
This invention relates to wind engines or as they are commonly termed wind-
mills, the object of the invention being to provide an engine or mill that shall be
especially adapted for use in places where sudden changes of the air currents
prevail.
The apparatus of my invention consists of a number of sails or slats mounted
between a pair of hoops which are carried by a post or standard. The post is
provided with an upwardly extending tube or pipe which carries a sleeve formed
with a cam groove in which rides a slide to which is secured a connecting rod
which transmits the power.
This sleeve carries a number of radial arms to the
ends of which are secured vertical tie rods or distance pieces that carry the hoops
between which the sails are pivoted. The inward movement of the sails is limited
by an inner hoop carried by spokes that extend radially from a hub the lower end
of which is formed with a series of inclines which are complementary to inclines
that are formed at the upper end of the sleeve. To the hub I connect rods that
are in turn pivotally connected to rods which carry weights, which latter rods are
in turn pivotally connected to the upper one of the pair of hoops. This arrange-
ment serves as a governor as hereafter referred to.
In connection with the parts described I arrange a heavy spiral spring one end
of which is connected to one of the main arms or spokes while its other end is con-
nected to one of the spokes which support the inner hoop the tendency of which
spring is to act in opposition to the governor. About the upper portion of the
tube I mount a cage which carries a ring, said ring being normally held against a
stop ring by a spiral spring. To the cage there is connected a cord or rope which.
passes over sheaves to a lever that is mounted at one edge of a tank, one arm of
the lever carrying a float which when the water within the tank has reached the
desired height will act to throw the lever up so that the cage will be drawn down,
this movement of the cage being designed for a purpose which will be hereinafter
explained.
In order that the sails may be controlled and act to bring about a certain speed
of revolution irrespective of the strength of the wind, I provide fingers that are
pivotally mounted upon rods carried by the hoops the inner ends of these fingers
passing through staples that are carried by the hoop which limits the inward
movement of the sails. There is an outer hoop provided, so that if the wind is
light the inner and outer hoops serve to limit the play of the sails but if the wind
be strong so as to bring about too rapid a revolution of the wheel the governor
weights will fly outwards and in so flying outwards will draw upon the rods and
these rods will turn the hub and cause such hub to rise until it bears against the
under face of the ring, the frictional contact of the hub and ring tending to check
the travel of the inner hoop and consequently the main hoops will travel faster
than said inner hoop for an instant in such manner that the fingers will act to
hold the sails in a position such that they will be at all times practically tangential
to the main hoops.
If the engine is used for pumping and sufficient water has been pumped into the

page_text: tank, the rising of the float will draw down the ring and the same checking of th
movement of the hoop will be brought about.

COMPLETE SPECIFICATION.
Improvements in Wind Mills or Wind Engines.
I, IRA ALLEN JEFFERSON, of Park City, in the County of Summit, and
Territory of Utah, United States of America, Carpenter, do hereby declare the
nature of this invention and in what manner the same is to be performed, to b
particularly described and ascertained in and by the following statement :-
This invention relates to wind engines or as they are commonly termed wind
mills, the object of the invention being to provide an engine or mill that shall be
especially adapted for use in prairie regions or other places where sudden changes
of the air currents prevail.
To the end above named, the invention consists of certain novel constructions
arrangements, and combinations of elements, which will be hereinafter described
and specifically pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar figures and letters of reference indicate corre
sponding parts in all the views.
Figure 1 is a plan view of my improved wind engine, the parts being represented
as they would appear if the wind were light and were moving in the direction of
the arrow shown in connection with the figure.
Figure 2 is a similar view, the parts however being represented as they appear
when a strong wind prevails.
Figure 3 is a sectional elevation of the wind engine or mill.
Figure 4 is a sectional elevation of the central section of the mill, and
Figure 5 is an enlarged detail view of the regulating attachment.
In
In the drawings 10 represents a post or standard which is provided with an
upwardly extending tube or pipe 11 upon which there is mounted a sleeve 12 that
is formed with a cam groove 13 in which there rides a slide 14 to which slide
there is secured a connecting rod 15 which transmits the power. The sleeve 12
carries a number of radial arms 16 to the ends of which arms there are secured
vertical tie rods or distance pieces 17 that carry hoops 18. The sails 20 are
pivoted between the hoops 18 and their inward movement is limited by a hoop 21
carried by spokes 22 that extend radially from a hub 24, the lower edge of said
hub being formed with a series of inclines a which are complementary to inclines b
that are formed at the upper end of the sleeve 12. To the hub 24 I connect
rods 25 that are in turn pivotally connected to rods 26 which carry weights 27,
the rods 26 being in turn pivotally connected at ee to the upper hoop 18.
connection with the parts described I arrange a heavy spiral spring 30 one end of
said spring being connected to one of the main arms or spokes 16 while the other
end of the spring is connected to one of the spokes 22 which support the hoop 21
the tendency of the spring being to throw the parts to the position in which they
are shown in Figure 1, that is to throw the hoop 21 in the direction of the arrow
shown at d. About the upper portion of the tube 11 I mount a cage 32 which
carries a ring 33 said ring being normally held against a stop-ring 34 by a spiral
spring 35. To the cage 32 there is connected a cord or rope 36 which extends about
sheaves 37 and 38 to a lever 39 that is mounted at one edge of a tank 40 the long
arm of the lever 39 carrying a float 41 which when the water within the tank has
reached the desired height will act to throw the lever 39 as indicated by its arrow
and as the lever 39 is so moved the cage will be drawn down, 'this movement of the

page_text: cage being designed for a purpose which will be hereinafter explained. In order
that the sails 20 may be controlled and act to bring about a certain speed of
revolution, irrespective of the strength of the wind. I provide fingers 50 that are
pivotally mounted upon rods carried by the hoops 18, the inner ends of these
fingers passing through staples 51 that are carried by the hoop 21. Beyond the
hoops 18 arrange an outer hoop 43.
If the wind is light the hoops 43 and 21 serve to limit the play of the sails or
fans as is indicated when the parts are affected as represented in Figure 1 but if
the wind be strong so as to bring about too rapid a revolution of the wheel, the
governor weights 27 will fly outward and in so Hying outward will draw upon the
rods.25 and these rods will turn the hub 24 and cause such hub to rise until it
bears against the under face of the ring 33 the frictional contact of the hub and
ring tending to check the travel of the hoop 21 and consequently the hoops 18 will
travel faster than the hoop 21 for an instant and the relative position of the parts
will be as represented in Figure 2 and when the parts are so relatively located the
fingers 50 will act to hold the sails or fans in a position such that they will be at all
times practically tangential to the hoops 18. If the engine is used for pumping
and sufficient water has been pumped into the tank.40 the rising of the float will
draw down the ring 33 and the same checking of the movement of the hoop 21
will be brought about.
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. In a wind-engine, the combination, with the sail-carrying frame, of pivotally-
