page_text: I, SAMUEL SAUNDERS, of 36, Broadway, Barking, in the County of Essex,
Furniture Dealer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved wind-motor.
The object of my said invention is to better utilize the force or pressure exerted
by the wind for driving mills and for other purposes, and the said invention com-
prises improved means for accomplishing this result.
In carrying my invention into practice I mount two shafts in suitable bearings
and I pass around suitable pulleys on the said shafts one or more endless bands
or chains. On the said endless bands or chains I provide wings, sails or vanes
capable of being held up to the wind and also capable of folding in so as to
present but very little resistance to motion through the air in the return part of
the revolution.
I provide suitable trips for altering the position of the wings, sails or vanes
and also suitable means for keeping them up before the wind.
I prefer to employ three of the said wings, sails or vanes so as to have always
one in the full working position; I may, however, use more or even less.
On one or both ends of the shafts I provide a pulley or pulleys for transmitting
power to other shafts or to apparatus to be operated by my improved motor.
The said shafts with the endless bands or chains are mounted in a frame or
support capable of rotation about a vertical pivot or axis so that the apparatus
can be set or adjusted according to the direction of the wind, so as to secure the
best results. If desired, the said frame or support is provided with means whereby
it will be automatically turned as required by the force of the wind.
Dated this 30th day of June 1897.

page_text: I, SAMUEL SAUNDERS, of 36, Broadway, Barking, in the County of Essex,
Furniture Dealer, 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:→
My invention relates to an improved wind-motor, and has for its object to
provide for the utilization, in a more efficient manner than heretofore, of the
force or pressure exerted by the wind for driving mills and for other purposes.
An important feature of my said invention is the employment of wings, vanes
or sails which are mounted upon endless bands or chains passed around suitable
pulleys or sprocket-wheels and which are capable of being expanded or set so
that the wind will drive them in one direction, and of being then folded or furled
so as to offer but slight resistance to the wind during their return motion.
The shafts on which the said pulleys or sprocket-wheels are fixed are supported
in a suitable frame, which is preferably mounted on a vertical pivot and provided
with means whereby it can be automatically turned by the force of the wind to
bring the vanes or sails into their proper position relatively to the wind, when
any variation in the direction thereof occurs. One or both of the said shafts are
connected in any convenient manner by belt or other gearing with the shaft or
shafts to which motion is to be imparted.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a side elevation, and
Figure 2 an end elevation of one form of my improved wind-motor.
Figures 3, 4 and 5 are different views hereinafter referred to, illustrating
details of construction.
Like letters indicate corresponding parts throughout the drawing.
a is a frame or gantry mounted upon a vertical pivot a¹, and also supported
by rollers a² running upon a circular rail or track. The frame a supports
bearings for rotary shafts b, on which are fixed sprocket-wheels 63. Endless
chains c are passed around the said sprocket-wheels 62 and to these chains are
attached at suitable intervals sail-frames d in which are arranged sails d' made
of canvas or other suitable material. Each sail is secured along its upper edge
to the top of the frame d and has at its lower edge a weighted bar & which slides
up and down in suitable guides in the uprights or sides of the frame d, and
stretches or sets the sail between itself and the top of the frame when the said
frame is above the chain, and causes the folding or furling of the sails when the
frame is inverted, that is to say, before the commencement of its return movement.
To keep the sail-frame d in a vertical or nearly vertical position during the
operative part of its travel and to support it during its return motion, it is pro-
vided with rollers e turning upon pins fixed in rods or stays el extending from
the frame d, or in the sides of the said frame as the case may be, which rollers
engage with guide-rails e respectively, fixed in the frame a and extending
parallel with the chain c.
For supporting the sail-frames while passing around the sprocket-wheels 63,
arms ƒ are fixed upon the shafts 6 and are provided with spring or weighted
latches g adapted to enter notches ¹ in inclined plates h attached to the sides
of the frame d, as shown in Figures 3, 4 and 5.
At the proper times, the said spring latches 9 are disengaged from the slots ¹

page_text: by inclined releasing trips which are secured to the frame a and which engage
with tail-pieces g¹ of the said latches as the arms f move past the said trips k.
A pulley mounted on one of the shafts b, is connected by a belt ¹ with
another pulley 12 keyed upon a shaft which communicates the motion through
bevel-gearing m, m¹ to a vertical shaft n extending through the pivot a. This
shaft n is geared through bevel-wheels p, 2' to the shaft r which is to be driven
and which may be the main shaft of a mill or other machine. By this combina-
tion of parts I provide for the rotation of the frame about the axis of the vertical
shaft without affecting the relation of the parts.
I prefer to employ three sails as shown, so as to always have at least one in
the full working position; I may, however, use a larger number of sails if
desired.
The action of the wind upon the sails when extended between the top of the
frames and the corresponding weighted bars drives the chains c in the
direction indicated by the arrow. As either sail-frame d approaches the end of
its operative travel, the arms f at that end of the machine will overtake it, so
that, at the instant when the said sail-frame is brought vertically over the axis
of the right-hand shaft b (Figure 1) the latches g of the said arms f will pass over
the inclined faces of the plates h respectively and engage with the notches h¹
thereof and the said arms f will support the said frame d while its rollers e are out
of engagement with the guide-rails e³, and will carry the said frame angularly
downward. On meeting with the inclined faces of the corresponding releasing
trips k, the latches g will be disengaged from the frame d, so that the arms f can
move away from the said frame. During this movement of the frame d, the sail
is folded or furled by the weighted bar de sliding down in the frame d. The sail-
frames are similarly lifted by the arms f at the other end and released after the
rollers e engage with the rails e, the sail being at the same time spread or set
by the return movement of the bar d².
The frame a is capable of rotation about its vertical pivot or axis a¹ so that
the apparatus can be set or adjusted, according to the direction of the wind in order
to secure the best results. A pawl s secured to the underside of the frame a
engages in one or other of a series of notches in the edge of a plate s¹ forming
part of the pedestal s², so as to restrain the said frame a from rotation when set
in position. Or, if desired, the said frame or support is provided with any well-
known means whereby it will be automatically turned as required by the force
of the wind so as to keep the sails in the most advantageous position notwith-
standing changes in the direction of the wind.
It obvious that I can, if desired, use other forms of folding or adjustable
vanes or sails in the manner hereinbefore described.
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: -
First. A wind-motor in which vanes or sails are mounted upon endless bands
or chains passing around pulleys or sprocket-wheels and are adapted to be
expanded or set so that they will be driven in one direction by the wind and to be
then folded or furled so as to offer but little resistance to the wind during their
return movement, substantially as hereinbefore described.
Second. In a wind-motor, the employment of frames attached to endless bands
or chains and provided with loaded sails which set themselves when their frames
assume the operative position and furl themselves when the said frames are
inverted, substantially as, and for the purposes, above specified.
Third. The combination, with the vanes or sails attached to the endless bands
or chains, of, means for supporting the said vanes or sails during their partial
rotation about the axes of the pulleys or sprocket-wheels, substantially as, and
for the purposes, hereinbefore described.

page_text: Fourth. The improved wind-motor, constructed substantially as described with
reference to the accompanying drawing and operating as, and for the purposes,
above specified.
