Improvements in or connected with Wind-motors.
I, WILLIAM CALVERT BRAMWELL, of Hyde Park, Massachusetts, United
States of America, do hereby declare the nature of this invention to be as
follows:-

This invention relates to an improved construction of wind-wheel and to means or
methods of transmitting its motion to a machine or mechanism such as a dynamo.
Wind-wheels as heretofore constructed have been too cumbersome to satisfactorily
answer the purpose of motors. Moreover the gear employed for transmitting the
power from such wheels has been complicated and heavy with the result that the
greater part of the motive power has been absorbed by the friction produced
during working, and therefore in order to accomplish any successful results it has
been necessary to erect wind-wheels of extraordinary dimensions.

"
For the purpose of my invention I construct the wind-wheel on the "tension'
principle, as distinguished from the old method or compression principle,
whereby I am enabled to produce an extremely light and strong wind-wheel which
will revolve freely in light winds and one that will attain a higher velocity and
develop more power than ordinary wind-wheels constructed on the compression
principle. The wheel may have radial or tangent sails with or without tension
braces and the hub and the rim may be of any suitable construction, but in every
case the connecting members between the said hub and rim will be subjected to
tensional strains. In other words only the rim will be in compression, so that the
said wheel will be supported from the rim in an analogous manner to a bicycle
wheel, instead of from the hub like an ordinary wagon wheel. Ball-bearings may
be advantageously employed for the wheel.
In order to simplify the transmission of the power from the wheel I propose to
abandon the generally employed vertical and horizontal shafting with bevel gears
and speed increasing devices, and to transmit the power from the rim of the wheel,
or from some point contiguous to the rim, direct to the machine or mechanism to
be driven. This may be effected by means of a flexible connection such as an
endless rope, chain, or belt, or by frictional contact of the rim of the wheel with
the rim of the pulley or wheel to be driven. Or the wind-wheel may have a
toothed rim gearing with a toothed pinion on the machine to be driven. The
requisite speed of the driven mechanism can thus be obtained directly from the
wind-wheel without loss of power in transmission. For enabling this method of
power transmission to be practically carried out, the machine or mechanism with
which the wind-wheel gears is made movable so that when the position of the
wind-wheel is altered to suit the direction of the wind, the machine or mechanism
will also be shifted. This may be effected by mounting the machine or
mechanism on the same vertical support or standard carrying the wind-wheel,
suitable means being provided for transmitting the power from the wind-wheel
through a bearing in the roof of the building or tower to the machine situated
below. The aforesaid support or standard may be furnished with ball bearings.
Suitable means are provided for always maintaining the wind-wheel towards the
wind and I also provide means for enabling the motion of the said wheel to be
conveniently regulated or stopped.

WICH
I, WILLIAM CALVERT BRAMWELL, of Hyde Park, Massachusetts, United
States of America, Mechanical 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 invention relates to an improved construction of wind-wheel and to
means or methods of transmitting its motion to a machine such as a dynamo or
a pump.
Wind-wheels as heretofore constructed have been too cumbersome to satisfactorily
answer the purpose of motors. Moreover the gear employed for transmitting the
power from such wheels has been complicated and heavy, with the result that a
large proportion of the motive power has been absorbed by the friction of the
working parts and therefore in order to accomplish any successful results it has
been necessary to erect wind-wheels of very large dimensions.
For the purpose of my invention I construct the wind-wheel on the “tension"
principle, as distinguished from the old method or ❝ compression principle,
whereby I am enabled to produce an extremely light and strong wind-wheel which
will revolve freely in light winds and one that will attain a higher velocity and
develop more power than ordinary wind-wheels constructed on the compression
principle. The wheel may have the sails or blades arranged radially or
tangentially with respect to the hub with or without extension braces, and the
hub and the rim may be of any suitable construction, but in every case the
connecting members between the said hub aud rim will be subjected to tensional
stresses.
It will be understood that when the word "tension" is herein employed, it means
a powerful force applied in the direction of the length of the members and tending
to strain them to the utmost extent, not merely to make them tight, but to supply
a sufficient stress to enable them to withstand gales and storms without resorting to
members of large section. A wheel thus constructed has all its members in tension
except the rim which is in a high state of compression; the wheel therefore
possesses great rigidity and durability. It will be readily seen that a wind-wheel
constructed according to this invention bears the same relation as to lightness and
strength, when compared with ordinary wind-wheels, that a bicycle wheel does to
an ordinary waggon wheel.
In order to simplify the transmission of the power from the wheel I propose to
abandon the generally employed vertical and horizontal shafting with bevel gears
and speed increasing devices, and to transmit the power from the rim of the wheel,
or from some point contiguous to the rim. This may be effected by means of a
flexible connection such as an endless rope, chain, or belt, or by frictional contact
of the rim of the wheel with the rim of the pulley or wheel to be driven. Or the
wind-wheel may have a toothed rim gearing with a toothed pinion on the machine
to be driven. The requisite speed of the driven mechanism can thus be obtained
directly from the wind-wheel without material loss of power in transmission. By
the methods of driving heretofore adopted long shafts are used of considerable size
and weight, with many bearings, causing considerable loss due to friction whereby
large percentage of the power developed at the wind-wheel is dissipated before
it reaches the machine to be driven. Very large wheels have therefore to be used
to obtain any substantial power in light winds, and as the speed of the wheel shaft
becomes less as the diameter of the wheel increases, additional speed increasing
devices have to be introduced, thus considerably diminishing the advantage of the
larger wheel. The driving of an electric generator (whose armature requires a
a

page_text: high speed before current is generated) by means of a slowly moving wind-wheel
haft has presented such a difficult problem that nearly all attempts to solve it have
had to be abandoned.
For enabling my improved method of power transmission to be practically
carried out, the machine or mechanism with which the wind-wheel gears is made
movable so that when the position of the wind-wheel is changed to suit the
direction of the wind, that of the machine or mechanism will also be changed to
correspond. This may be effected by mounting the machine or mechanism on the
vertical support or standard that carries the wind-wheel, suitable means being
provided for transmitting the power from the wind-wheel to the machine or
mechanism situated below.
Where high speed is not essential, as for pumping purposes, I use the wind-wheel
shaft in the usual manner for driving the pump rod, but I have simplified the
mechanism, as will be hereinafter described.
This invention also comprises improvements in rudders for wind-motors, whereby
the speed is automatically regulated by the action of the wind so that excessive
speeds are prevented and the motion is stopped when required.
In order that my invention may be clearly understood I will now describe the
same with reference to the accompanying drawings, in which
Figure 1 is an elevation, partly in section, of a wind-motor and dynamo and the
driving connections between them.

wind-wheel.
Figure 13 is a front elevation of a portion of the wind-wheel illustrated in
Figure 12 showing one of the wind-blades.
Figure 14 is a plan of the rudder shewn in Figure 12.
Figure 15 is a vertical section of the rudder and governor shown in Figure 12.
Figures 16 and 17 show in elevation and plan respectively a modified construction
of governing mechanism.
Figure 18 is a plan of a further modified form of rudder and governor, the
adjusting mechanism being omitted.
Figures 19 to 23 illustrate details of the blades hereinafter referred to.
Referring to Figures 1 to 11, A is a hollow rotary standard that supports the
wind-wheel and the machine to be driven, in this instance a dynamo. B is a hub
having cup shaped ends bb'. C is a rim of approximately U shaped section;
DD are sheet metal wind-blades; E, E are holders fixed to the rim by bolts and
nuts e Figure 4; F, F¹ Figure 2, are screw threaded rods and ff are nuts by
which said wind-blades are tensionally strained between the hub and rim. The
wind-blades are made of any suitable sheet metal for example of iron, brass or
steel, their ends being bent over upon themselves and rivetted; a wire or rod
passes through the bent loop at each end, and also through eyes in the ends of the
forked holders E, notches being cut through said loop, to receive the ends of the
holders as indicated in Figure 2. The lower ends of the blades are bent around
the T-shaped heads of the bolts F F which pass through the flanged ends of the

page_text: hub as clearly shown, and which are screw threaded to receive the nuts f¹ whereby
they can be tightly strained.
In order that the wheel may have stability, the wind-blades are alternately
fastened to the front and to the back ends of the hub as shown. They may all,
however, be secured to the front end of the hub if, instead of the blades D', brace
wires are secured to the back end of the hub. Or all the blades may be fastened
to the back end of the hub, and the braces to the front end; or the bub may bave
a central flanged, or other dise, to which the blades are fixed, the wire or other
braces then being alternately fixed to the front and hack ends of the bub; more-
over other arrangements can be used without departing from the spirit of my
invention. The blades are shown arranged radially to the hub, but it is to be
understood they may be arranged tangentially thereto.
The wheel so constructed is complete in itself, and can be put on or taken off its
supporting shaft G without dismembering it in any way.
The hollow standard A also carries a rudder H which may be of thin boards,
held by their ends in grooves in the inner edges of the arms g and g, Figure 1,
which arms are bolted to a casting I having a hub, or hubs, through which passes
a pin h, said pin being held in the arm Jof the head casting K fixed to the
standard, and the whole being so arranged that the said rudder can be turned upon
the pin as upon a hinge to adjust its position relatively to the wheel. The head
casting K has extended arms; and, Figure 8, carrying the shaft of a worm k
which gears with a segmental toothed casting L fixed to the rudder. The shaft of
said worm has fixed on it a sprocket or other wheel which is driven by a chain or
rope m. Said chain passes over guide pulleys n and n¹ and extends down the
interior of the standard A to a convenient position where it can be operated
through a sprocket or other wheel p fixed to a shaft which is furnished with a
crank handle on the outside of the standard. By turning said handle the rudder
can be adjusted to a new position relatively to the wind-wheel. If said rudder is
in the position shown in Figure 1, i.e. at right angles to the face of the wheel, the
latter will be in its best position for revolving, being exactly in the eye of the
wind, but if the rudder is turned until it is parallel with the wheel, the latter will
then have its edge to the wind and will consequently cease revolving.
In order that the driving pulley M of the dynaino N may always maintain its
alignment with the rim of the wind-wheel, during changes in the direction of the
wind, carry said dynamo or generator N upon a platform O, Figures 1 and 9,
fixed to the standard A, so that whatever position the wind-wheel assumes under
the action of the wind upon the rudder, the dynamo is carried with it. To protect
the dynamo from the weather, a removable cover P is provided. The platform O
is secured by the set screw upon slacking which the platform may be raised or
lowered to suit the length of the driving rope S.
The standard A has a bearing T1 in the roof T of the tower or other building
through which the said standard passes, and rests at its lower end upon a ball-
bearing step within said building, as shown at t and u, so that it is free to rotate in
accordance with the changes in the wind's direction. is a cover for protecting
the bearing T from the weather. The brushes of the dynamo, Figure $9, are
furnished with connecting wires passing through insulators to the interior of the
standard A, down which they pass to any desired point, where their ends are
connected to insulated rings 1 and 2 Figure 1. Against these rings press stationary
contact brushes 3 and 4, to which are attached wires 5 and 6 for conveying the
current to storage cells, or elsewhere as desired.
Figure 10, shows in elevation, part of the standard A having a forked arm 7 and
collar 8 fixed to the standard. To this arm is pivotted one side of the base of the
dynamo N. 9 is another collar fixed to the standard and constructed to carry
pulleys, 10 and 11, forming guides for chains, or cords fixed to the dynamo at one
end, and having counterbalance weights 12 and 13 at the other end so arranged
as to partially balance the dynamo, the unbalanced part of the weight being
supported by the driving band or rope S.

page_text: The weights are so proportioned as to give the required tightness to the driving
helt or rope. Springs may be substituted for the weights. In some instances
only one pulley and counterbalance weight are used. The collars 8 and 9 are held
by set screws to the standard, and may be lowered and raised to suit the length of
the belt or rope.
Figure 6 shows a roof bearing constructed to allow the driving rope S to. pass
through it, to drive a dynamo or other machine within the building. The bearing
comprises a large annular ring 15 fixed to the roof by bolts or otherwise, the roof
being pierced with a large central opening. Fixed to the stan.lard is another
ring 16 having its top part solid, except where the driving rope passes through it;
this ring answers as a cover to keep out rain and snow. Between these two rings
a series of balls are free to rotate, furnishing a comparatively frictionless bearing
for the standard, the lower end of which rests upon a step bearing as shown in
Figure 1. To guide the driving belt or rope and bring it within the circumference
of the hearing, pulleys 16 and 17 are provided on arms 18 and 19, Figure 7, which
arms are carried by a collar 20, fixed ou the standard A.
Figure 5 shows a circular or tubular ring C; the holders E are slid upon it and
are placed at the required distance apart; they hold the wind-blades D by means
of screw rods a, passing through the arms of the holder, and nuts a' for tightening
the blades; thus the tensional strain is imparted to the blades in Figure 5, at, or
near the rim of the wheel, instead of at the hub as in Figure 3. Each holder is
furnished with a forked projection C', and since the holders are comparatively
close together upon the rin, these forks answer well as bearings for the driving
rope, and as a substitute for the U shaped rim before described.
Although belts or ropes are referred to as connectors between the rim of the
wind-wheel and the driving pulley of the dynamo or other machine toothed gearing
may be employed, by fixing to the rim segmental toothed pieces meshing with a
spur gear on the driving shaft of the machine; or said shaft may be driven by
frictional gear.

Referring, now to Figures 12, 13 and 14, the wheel therein shown has a rim 30,
of comparatively thin fat metal having a width suited to the sails. Two rows of
holes suitably spaced are drilled through said rim, one near each edge, and one row
being in advance of the other a distance in accordance with the angle the sails are
desired to have. 31 is the cast hub, furnished with flanges or discs 32 and 33. The
latter has a rim or flange 33* as shown on each side of it and holes drilled through
the same corresponding to the holes in the rim 30. The flange 32 is also pierced
"
وو
with a series of holes, and there are corresponding holes through the centre of the
rim. 34 and 35 are tension rods which are passed through the holes near the
edges of the rim, and through the holes in the flanges 33*. These rods are
staggered across the rim and the hub flange alternately from side to side so as
to determine the angle of the sails. The brace wires 36 are passed through the
central holes in the rim, and are connected at their inner ends by bolts 37 to the
flange 32. All the rods 34, 35 and 36, have their ends screw-threaded and are
provided with nuts by which they are very tightly strained and thus the rim is
made rigid and true with the hub. The distance apart of the hub ends is greater
than the width of the rim, so that when the tensional strain is brought upon all the
wires in proper proportion the rim is fixed substantially over the centre of the
length of the hub.
A wheel thus constructed is in principle similar to a large bicycle wheel with a
flat rim, the difference in constructive detail being such as to adapt it to be
operated by the wind. The flanges 33* of the disc 33 are narrower than the
circumferential rim of the wheel, and the tension rods 34 and 35 correspondingly
approach each other toward their inner ends, and it is to these that the wind blades
are attached, thus they serve the double purpose of tension spokes and holders for
the blades or sails. The wires or rods 36 at the back of the wheel are tension
braces, and may be arranged further apart than the tension rods 34 and 35 at the
front.

page_text: Figure 19 is a section of a wooden blade having grooves parallel with its edges,
to correspond with the tension rods 34 and 35. By pressing it against said rods
until they become embedded in the grooves, and then moving it lengthwise toward
the rim, it becomes wedged, and can be fixed in that position by means of staples
or otherwise. Figure 23 shows the shape of the blade lengthwise. Figure 20 shows
in section a wooden or papier-maché blade, secured to the tension wires 34 and 35
by small staples, which are driven through and clinched or bent over on its face.
Figure 21 shows in section a sheet metal blade secured by having its edges bent
around the tension wires 34 and 35. Figure 22 shows in section a wooden blade
having grooves in the outer edges for the wires 34 and 35. Figure 13 shows a
blade fixed in position in the wheel.
The complete wheel is fixed by the set screw 38, in the modification shewn
by Figure 12, upon a spindle 39 whose end carries a crank or disc for driving a
pump. 40 is a casting having a hub 41 with interior annular flanges, forming
bearings for balls, as shown in conjunction with a collar 42, fixed to the supporting
hollow standard 43. The hub and standard are shown in section in order to more
clearly exhibit the ball bearings at the top and bottom of the hub 41. The
casting 40 is constructed with a bearing 44 for receiving the wheel spindle and
with an oil cup 45 communicating with a receptacle below the bearing; the said
receptacle contains a wick communicating with the spindle, through holes or a
longitudinal slot, so as to feed the oil to the spindle.
The rudder casting 46 is hinged, as shown, to the casting 40 and to it are bolted
the arms 47, which may have grooves in their inner edges for holding the thin
boards forming the rudder blade as shown. The arms 47 are bent, as shown
in Figure 14. 49 is a wing hinged to the rudder near the bend, the normal position
of this wing is open, it being held in this position, by the action of a weight or
spring. In Figures 14 and 15 a flat weight 50 is shown suspended from the inner
ends of the toggle arms 51 the other ends of which are loosely fixed to the sides of
the rudder and the wing. The downward pressure of the weight keeps the wing 49
open as far as permitted by the chain 52. Should the wind increase in force
sufficiently to press the wing inwards, and thus raise the weight, the rudder, and
with it the wind-wheel would be turned partially around the hollow standard 43
by the pressure against the angular portion of the rudder a distance proportionate
to the wind's pressure, and would thus bring the wheel to a less favourable position
for being rotated by the wind. This device thus forms a governor, and prevents
excessive velocities of the wheel.
Figures 16 and 17 show a similar rudder, but in this form the normal position of
the wing is closed, or parallel to the rudder, and it is only opened or turned to an
angular position (see dotted lines) when required to counteract high velocities of
the wind and such as are above a pre-determined maximum. 54 is a lever having
a plate 55 fixed to its upper end, its lower end being journalled on a stud or pin 56,
carried by the rudder. At 57 it carries 'a pin, to which is hinged one end of a
link 58 whose other end is hinged to a pin carried by an arm 59 which is fixed to
the rod carrying the wing 60 by means of the hinges 61. The spring 53 is
attached at one end to a tail piece 62 of the lever 54 the other end of the spring
being fixed to the rudder. The pressure of the wind on the plate 55 turns the
wing 60, as shown by dotted lines in Figure 17 and thereby indirectly adjusts the
wind-wheel to a new position. A weight may be used in lieu of the spring.
Another modification of governor is shown in Figure 18. The wing in this case
is pivoted at or near its centre, and can swivel as shown by dotted lines. This
form of governor is operated by mechanism similar to that shown in Figures 16
and 17.
It will further be understood that the governing arrangements fixed to the
rudder, as herein described, are not affected by the wind until its force or pressure
becomes greater than desired, when they become active, and prevent undesirable
velocities of the wheel. An ordinary "side vane or auxiliary rudder, such as is
generally used, acts uninterruptedly and does not permit the wheel at any time to
33

page_text: squarely face the wind even in light breezes, and hence is not a governor in the
sense herein intended.
To start or stop the wind-wheel, I make use of the pump rod which of necessity
extends to or nearly to the ground, in a conveniently accessible position without
the necessity of climbing to the top of the tower or building. The pump rod 69
passes through the top of the hollow standard 43, Figure 12, and has loosely
mounted on its upper end a sleeve, held in position by collars fixed to the rod.
To the sleeve the forked pump pitman 63 is connected by the pins 64. Thus the
pump rod is free to turn around its centre while being reciprocated by the pitman.
At the top of the standard 43 a bearing (shown in section) is fixed and through
this an elongated hub passes, having a collar below the bearing and a gear wheel 70
above. This gear wheel has a square or non-circular hole through it, to receive
the rectangular or similarly formed portion of the pump rod so that if the rod is.
turned the gear wheel must turn with it. To the rudder is fixed a pin 65' passing
through a hole or slot in the segmental gear 66, (Figures 12 and 14), which is."
carried by the pivot rod 67 of the rudder, and gears with the small gear wheel 70,
through which the pump rod passes. At any convenient place upon the pump rod
a crank may be geared to turn it by, as at 68 Figure 12, and it is evident that by
turning the said rod the rudder is turned and the wind-wheel is adjusted with its.
face or its edge to the wind. At each end of the toothed face of the segmental
gear 66 an extended tooth acts as a stop against the small gear wheel to limit the
turning movement of the segment.
By thus utilizing the pump rod to start and stop the wind wheel, much cumbrous
mechanism is dispensed with.
It will be understood that this improved wind motor is not restricted to pumping
purposes as by countersinking the ends of the tension spokes 34, 35, 36 into the
outer surface of the wheel rim 30, the latter could be used as a belt-pulley to drive.
a shaft or machine.
Other means than those shown may be employed for attaching the wind blades.
and also for use in producing the tensional strain in the wires or rods, such as turn-
buckles, and the like. The tension members may be arranged tangentially to the
hub, instead of radially as shown, and other modifications may be made in the
construction without departing from the spirit of my invention which is not confined
to the special arrangements shown and described.
