Improvements in Wind Motors.
...ft
I, RICHARD LUNDQVIST, Merchant, of Laguna de Terminos, Mexico, United
States of America, do hereby declare the nature of-my, 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 wind motors having wheels of the horizontal class; and
the object of my invention is to produce a simple, strong and easily controlled wind
motor having a wheel arranged to turn horizontally and with blades adapted to get
the full force of the wind and to feather nicely when returning through it, also
to provide a very strong, simple and convenient means for transmitting power
from the wind wheel to a pair of pumps, a single pump or other mechanism, as
desired.
To these ends my invention consists of certain features of construction and
combinations of parts, which will be hereinafter described and claimed.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar figures and letters of reference indicate corresponding
parts in all the views.
Figure 1 is a broken side elevation of the wind motor embodying my
invention;
Figure 2 is a plan view of the same;
Figure 3 is a broken vertical section on the line 3-3 of Figure 2;
Figure 4 is a sectional plan on the line 4-4 of Figure 3, showing in detail the
roller bearing for the main shaft ;
Figure 5 is a sectional plan on the line 5-5 of Figure 1;
Figure 6 is a broken side elevation showing a modified means of transmitting
power from the main shaft ;
Figure 7 is a detail of one of the boxes used in the transmitting gear; and
Figure 8 is a broken detail view, showing the manner of supporting the pivots of
the several fans of the wind wheel.
The motor is provided with a horizontal wind wheel comprising in its construction
the two hubs 10 having radial arms 11 and the radially arranged U-shaped
frames 13, the ends of which are secured to the arms 11 by the long bolts 12
extending from the arms of one hub to those of the other, as clearly shown in
Figure 3. This construction of the wind-wheel frame enables it to be very easily
put together or taken apart, if desired. Arranged in a vertical position on the
frame are the fans 14, there being a series of fans ou each frame 13, and the fans
are pivoted at one edge, as shown at 15, the pivot pin of each fan extending
downward through the lower member of the frame and resting on a button 16
which is pivoted on the under side of the frame and is provided with a socket 17 to
receive the pivot pin.
When it is necessary to remove a fan the button may be turned to one side and
the fan dropped so as to permit the upper end of the pin 15 to swing from the
upper member of the frame 13, and thus the fan may be easily removed. The
movement, of the fans 14 is limited by stops 18 projecting from the upper and
lower edges of the fans and adapted to engage the cross braces 19 which extend
from one frame 13 to another and which are preferably jointed in the middle, as
shown at 20, and each brace is provided with a hook 21 at one end to engage the
frame
"

page_text: The stops of the outer fans 14 can only limit the inner movement of the said
fans, and hence means to be presently described are employed to limit their
outward movement. Each fan has also, on its back, a spring 22 which, in case the
fan is suddenly and violently slammed inward, strikes the next fan and prevents
excessive shock. The outward movement of the outer fans 14 is limited by
links 23 which are pivoted to the upper stops 18 of the said fans and which are
provided with eyes 24 to slide on the braces 19, and when the fans are moved
inward the links slide to a position substantially parallel with the braces, but when
the fans move outward the links extend at an angle to the braces and so prevent
the fans from swinging out too far.
The wind wheel turns horizontally and is secured to the reduced end 25 of the
main shaft 26, which is arranged vertically and terminates at the top in a cap 27,
from which, extend braces 28 connecting with the several frames 13. of the wind
wheel.
The shaft 26 is mounted in a ball bearing 29 which is supported on cross bars 30
of the tower 31, and the shaft is provided with a suitable flange 29 which rests on
the balls of the bearing, as shown clearly in Figure 3. The tower may be of any
usual construction, or the shaft may be supported on any structure strong enough
to sustain it. The shaft 26 extends through the top plate 32 of the tower and in
the centre of the top plate is a bearing ring 34 which encircles the shaft and has,
at the top, a flange 33 to rest on the plate 32, and at the bottom an inwardly
projecting flange 35 to support the bearing rollers 36 which turn vertically, see
Figure 3, and on which runs the bearing ring 37 carrying horizontal rollers 38
which bear against the shaft 26, and prevent the lateral movement of the shaft aud.
still permit it to run very easily.
The wind wheel has, on its under side, an annular flange 39 around which
extends the strap 40 of an ordinary strap brake, which strap is fixed at one end, as
shown at 41 in Figure 2, and at its other end is connected by a link 42 with one
end of a horizontally swinging lever 43 which is fulcrumed on a stud 44 on the
Hange 33 of the bearing ring and is held by a spring 45 so as to throw the strap
out of engagement with the flange 39. The outer end of this lever 43 is connected
to a cable 46 which extends downward over a suitable guide pulley 47, as shown in
Figure 2, to a point where it may be reached from the ground, and by pulling on
the cable the lever 43 is tilted and the strap 40 drawn against the flange 39 so as
to check or stop the wind wheel.
The main shaft 26 projects downward through the bearing 29 and is, at its lower
end provided with a crank 48 having a terminal eye 49, see Figure 5, which receives
the upper end of an inclined rock shaft 50 which at its lower end is stepped in a
suitable bearing 51 supported on a cross piece 52, and thus when the shaft 26
revolves the shaft 50 is turned around and around, its upper end describing a
comparatively large circle, as shown by dotted lines in Figure 1.
The shaft 50 is connected, by a brace 53, with a yoke 54 which straddles the foot
of the shaft and is, on opposite sides, provided with trunuions 55 journaled in
boxes 56 which are secured to the cross piece 52, and at opposite ends of the yoke
are projecting arms 57 which are pivotally connected to the upright connecting
rods 58 which are also pivoted at their lower ends to the pump rods 59 of
the pumps 60.
It will be seen that the movement of the shaft 50 causes the yoke 54 to rock on
the trunnions 55, and the oscillation of the yoke moves the connecting rods up and
down and thus simultaneously operates both pumps, but if it is desired to operate
but one pump, one of the connecting rods may be dispensed with and a counter-
balance fastened to that end of the yoke 54.
If it is desired to operate other mechanism than the pumps, the shaft 50 and the
connections below it are dispensed with and a shaft 61 arranged vertically in
suitable bearings beneath the shaft 26, the shaft 61 having, at its upper end a
crank 62 to interlock with the crank 48, as shown in Figure 6, and at its lower end
the shaft 61 is coupled to a shaft 63 which is stepped in a suitable bearing 64 and

page_text: is provided with a gear wheel 65 driving a gear wheel 66 of the horizontal shaft 67,
which is journaled in a bracket 68 and is provided with a crank 69 which may be
utilized to drive other machinery, or power may be taken from the shaft 67 in any
ordinary and convenient way.
The action of the wind wheel in turning will be clearly understood by reference-
to Figure 2. Supposing the wind to be blowing in the direction indicated by the-
arrows in the said figure, it strikes a set of fans 14 at A and so turns the wheel to
the right, the wind also striking strongly against the fans at B, but as the fans turn
round to the left they gradually swing outward into the wind until, as shown at C,
they come edgewise through it, thus affording very little resistance to it and, as the
wind strikes them almost full on one side it will be seen that the wheel is turned
with comparative ease.
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. In a wind motor, the wind wheel comprising a frame having radially projecting
frames with upper and lower members, a series of fans pivoted at their edges between
the members of the frames, and stops on the upper and lower edges of the fans to
limit their swinging movement, substantially as described.
2. In a wind motor, the wind wheel comprising a frame having radially arranged
members placed one above the other, cross braces connecting the several members,
a series of fans to engage the cross braces, and links pivoted to the outer fans and
arranged to slide on the cross braces, substantially as described.
3. The combination, with the wind wheel frame having upper and lower aligning
members, of the fans having pivot pins projecting through the members of the
frame, and the buttons on the lower frame members to support the pivot pins,.
substantially as described.
4. In a wind motor, the wind wheel, comprising a pair of hubs having projecting
arms, a series of U-shaped frames fastened to the arms of the hubs, and a series of
fans pivoted in the said frames, substantially as described.
5. The combination, with the wind-wheel and its supporting shaft, of the ball
bearing to carry the shaft, and the roller bearings to prevent lateral movement of
the shaft, substantially as described.
6. The combination, with the wind-wheel and its driving shaft, of the rock shaft
having its lower end stepped in a bearing and its upper end provided with a crank
connection with the main shaft, and the oscillating yoke driven by the rock shaft,
substantially as described.
7. The combination, with the main driving shaft, of the crank thereon, the rock
shaft journaled at its lower end and connected at its upper end with the crank, the
oscillating yoke straddling the rock shaft and journaled on opposite sides of the
shaft, and means, as the brace, for connecting the yoke and the rock shaft,.
substantially as described.
