LABAN B. KINNARD, OF JACKSONVILLE, TEXAS.
AIR CYCLE.Specification of Letters Patent.
Patented Aug. 1, 1922.
Application filed December 7, 1920. Serial No. 428,904.
To all whom it may concern:
Be it known that I, LABAN B. KINNARD, a
citizen of the United States of America, re-
siding at Jacksonville, in the county of
5 Cherokee and State of Texas, have invented
new and useful Improvements in Air Cycles,
of which the following is a specification.
The object of the invention is to provide a
vehicle of the aeroplane type which is adapt-
10 ed for operation by pedal power, variable in
extent to suit the load or the number of
proposed occupants by multiplying the driv-
ing pedals, and to provide in connection
therewith improved means for controlling
15 the direction of flight of the craft and sim-
plifying the adjusting means used in that
connection; and with this object in view the
inventon consists in a construction and com-
bination of parts of which a preferred em-
20 bodiment is shown in the accompanying
drawing, wherein:-
Figure 1 is a side view of an air craft em-
bodying the invention.
Figure 2 is a plan view of the same.
25 Figure 3 is a longitudinal section.
Figure 4 is a transverse section of the
steering fan.
The planes 10 and 11 of which two are in-
cluded in the illustrated embodiment of the
30 invention, although it will be understood
that the number is subject to modification as
in the ordinary practice, are arranged in
transversely extending relation with a frame
12 provided with laterally spaced front
35 wheels 13 and a rear wheel 14, the propeller
15 having a rearwardly extending shaft 16
mounted in suitable bearings in the frame
as indicated at 17. The spindles of the front
wheels are preferably'provided with cushion-
40 ing springs 18 to relieve the jar in making
a landing.
The driving pedals 19 of which one or
more sets may be employed to correspond
with the number of proposed occupants of
45 the craft, are arranged within convenient
reach of the driver's seat 20 and are oper-
atively connected with the propeller shaft
by speed multiplying gearing indicated at
21, it being understood that the gear ratio
50 may be varied to suit the number of sets of
driving pedals employed or may be varied;to suit the number of occupants of the car,
as in connection with other pedal driven
vehicles, it being deemed unnecessary to
specifically illustrate any particular form 55
of such gearing inasmuch as the type there-
of may be modified to suit the preference
of the builder.
The steering fan 22 is formed with four
blades of which two are vertically disposed 60
and two horizontally disposed, the vertical
blades alternating with the horizontal
blades. The fan is universally mounted at
an intermediate point in its length, as indi-
cated at 25, upon an upstanding extension 65
26 of the spindle of the rear wheel 14. The
vertically disposed blades are designed for
lateral steering and in order that they may
be swung on the universal connection 25,
there are employed the rods 28 having ter- 70
minal connections at their rear ends with
the forward edges of the horizontal blades
adjacent the corners, the rods crossing each
other and being terminally connected to the
extremities of a pivotally mounted handle 75
bar 29. Obviously the turning of the handle
bar in the direction it is desired the machine
shall proceed will effect the necessary move-
ment of the vertical blades of the fan to
insure movement of the machine in the de- 80
sired direction. The horizontally disposed
blades, being designed for ascension and de-
scension, are actuated by a rod 27 having a
pivotal connection at its rear end with the
upper of the vertical blades at the longi- 85
tudinal center of the latter and also a pivotal
connection at its forward end with the hand
lever 30. It is obvious that in the operation
of the device the driver while operating the
pedals may employ both hands for use with 90
the handle bar 29 and the lever 30 respec-
tively to control lateral movement of the
machine as well as vertical movement.
Having described the invention what is
claimed as new and useful is :- 95
An air cycle having air planes and a pro-
peller, a steering mechanism consisting of
a fan provided with radially disposed blades
of which two are vertical and two are hori-
zontal, the fan being universally mounted at 100
a point intermediate the length of the blades.
and control means for the fans consisting of1,424,653.
