An Improved Wind-motor.
I, HERBERT PERCY SAUNDERSON, of Kempston Road, Bedford, in the County
of Bedfordshire, Engineer, 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 wind-motor by the application of a principle of gearing and other improve-
ments hereinafter described will develop power derived from the wind which
can be applied for driving machinery or other purposes in a cheap and efficient
manner.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters
and figures marked thereon.
Fig. 1, is a front elevation of the wind-motor.
Fig. 2, is a side elevation.
Fig. 3, is a plan of the top, showing bridge casting.
By adapting the tube b the motor may be erected on steel or wood towers or
on buildings as described in my former Patents No. 6174 of 1894 and No. 29,520
of 1896, and it has many parts in common with them. The tube 6 forms a pivot
on which the main bracket revolves to face the wind. The vertical or body
portion of the main bracket e, is hollowed out to fit over the tube d, and has a
bearing fat the top, through which passes the vertical shaft g, continued through
the tube b, down the side of the mast a in suitable bearings to the bottom. The
bevel cog-wheel is fixed to the sail spindle s, and drives the bevel pinion p. on
the vertical intermediate spindle o, having on the top the spur wheel », that drives
the spur pinion m fixed to the vertical shaft g. The spur wheel has a tendency
to twist the motor out of the wind through the resistance of the vertical shaft,
to counterbalance this the arm r, that carries the sail spindles is placed at
such a distance from the pivot that the leverage thus obtained, absorbs the
tortional strain of the vertical shaft, and when gusts of wind strike the motor,
or when its work is lessened the pressure on the arm r, overcomes the resistance
of the vertical shaft g, and the vane. And the sails are blown back out of the
wind, thus in this manner the motor will regulate itself.
The vane is supported by two strong lugs cast on the main bracket with a
steel pin which passes through these said lugs to receive the hinge casting of
the vane, and is extended upwards beyond the main bracket in such a manner
as to form an additional support by suitable braces and rods to the vane as shown
in the drawing annexed.
This vane is made of sheet iron and arms or frame of tubing.
The movement of the vane is performed by a wires coming down the side of
the mast, to within reach of the operator, and connected with the socket r¹ and
irons 2, which are free to move up and down and carry with them the casting
or shoe

page_text: The casting moves up and down with y but is free to revolve with the main
bracket, and is caused to do so by a cast rib on the barrel part e and a corre-
sponding slot in a, a rod w then connects a, with the lever gwhich is joined to
the crank u, by a rod, passing through the arm t, which serves as a stop for
the vane.
the vane.
The crank u, is connected to the vane by the rod e, with joints at each end,
therefore the wire connected with z, and within reach of the operator controls
The weight on the lever g through the mechanism u, t, and v,
keeps the vane at right angles to the sails, the amount of weight determines the
pressure at which the sails shall turn from the wind thus regulating the speed.
The crank u is connected to the lever g by the casting which is part of the
cam f', thus when the stopping wire is pulled and the cam fi rises and lifts the
lever e which is carried by a pin passing through lug and pulls down the
rod which is connected to the strap hinged at m' and in turn carry the
coned brake ring so that when the wire is pulled for stopping and just before
the vane is fully closed the brake ring is forced into the cup portion of the
wheel, and thus as the motor is closed a brake is automatically applied.
the back of the said shaft s is placed a bridge casting p' which may be held in
position by the strap o on the one side and the vane lug on the other side, and
having a stop which can be adjusted by the screw q¹ the object of which is to
take the end thrust of the sail shaft s and thus keeping into proper mesh the
bevel wheels
and p.
At
On the mast a at a suitable distance from the ground for driving the machinery
is placed the bevel gear j, and horizontal shaft i, which is supported by the
fork, that swings on the hangers k, (which are bearers for the vertical shaft)
and takes with it a tube l, in which the horizontal shaft revolves. The tube
and shaft may be extended to any desired length having at the outer end a
safety clutch for driving machinery direct and which is constructed as follows:-
At the outer end of the tube is fixed a casting t¹ which is bored to make a bearing
for the shaft i on the end of which is keyed or pinned, the clutch driver y¹ over
which passes the clutch box which is smooth on the outside and notched on
the inside to correspond with and be turned by the driver y¹ the box ¹ is held
in position by the fork w which is attached to a rod passing through holes in the
lugs on the bearing casting th and to which is fastened the handle u¹ pushed
forward into position by the coil spring el.
It will thus be seen that by placing a clutch of suitable shape on the spindle
of the machines to be driven the box ¹ can be drawn back by the handle u¹ and
the shaft swung round to its position when by releasing the handle the box
clutch will of itself engage the shaft of any machines to be driven, standing
in a semicircle around the vertical shaft y.
Or the aforesaid bevel gear and bracket may drive an ordinary shafting with
pulley wheels and belts.
The vane and sails are constructed of sheet iron or steel in concave form with
gas tubing for arms and stays.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In wind-motors, the combination of the gearing with a wheel and sail
spinilles supported by a bridge with adjusting screw g¹, substantially as
herein described and according to the accompanying drawings.
2. In wind-motors, the combination of the cam movement ft and with lever e¹
straps and brake and the extension of the tail pin a¹ with its attach-
ments b, c, d, and j', as supports to the vane substantially as herein described
and according to the accompanying drawings.
