HENRY FLANAGAN, OF FORT WORTH, TEXAS.
AERIAL NAVIGATING APPARATUS.
999,105. Specification of Letters Patent. Patented July 25, 1911.
Application filed April 19, 1911. Serial No. 622,046.To all whom it may concern:
Be it known that I, HENRY FLANAGAN, a
citizen of the United States, residing at
Fort Worth, in the county of Tarrant and
5 State of Texas, have invented new and use-
ful Improvements in Aerial Navigating Ap-
paratus, of which the following is a specifi-
cation.
This invention relates to new and useful
10 improvements in aerial navigating appara-
tus and comprises various details of con-
struction and combinations and arrange-
ments of parts which will be hereinafter
fully described and then specifically defined
15 in the appended claims.
I illustrate my invention in the accom-
panying drawings, in which:
Figure 1 is a vertical sectional view longi-
tudinally through the apparatus. Fig. 2 is
20 a vertical sectional view showing parts in
top plan; and Fig. 3 is a detail view in ele-
vation of the controlling shaft.
Reference now being had to the details of
the drawings by letter, A designates the
25 frame of the apparatus which is mounted
upon suitable wheels A', and mounted
within said frame is a tubular shell B, hav-
ing open ends and extending the length of
the frame, and branching from the upper
30 portion of said shell is a similar tubular
shell D communicating with the shell B and
and having its top open. E designates a
standard which is mounted vertically with-
in said frame and has a collar E' fastened
35 about its circumference, which collar has
radial arms F to the angled ends of which
the upper end of the shell D is fastened.
Said standard is hollow and is provided
with a parachute plane H fastened by means
40 of guy wires K to the circumference of the
cylindrical outlined portion N of the frame.
Mounted in suitable bearings in the spider
arms 0, the inner ends of which are fastened
to the inner surface of the shell B, is a pro-
45 peller shaft L to one end of which a propel-
ler L' is fixed to rotate within the flaring or
funnel - shaped forward end of the shell,
while the opposite end of said shaft carries
a sprocket wheel J about which a sprocket
50 elhain J' passes and which latter is drivenfrom a sprocket wheel J2 upon the shaft J3
of the engine J4.
A shaft Q is journaled at points diametri-
cally opposite within the shell B and has a
cross bar Q' fixed to its upper end and a 55
rudder Q2 is fastened to said bar Q and is
adapted to have a lateral swinging move-
ment as the bar Q' is oscillated. Cords or
wires Q3 are fastened one to each end of
the bar Q' and pass about the pulleys Q4, 60
shown in top plan view in Fig. 2, and each
is fastened to a tread member Q5, which
tread members are pivotally mounted upon
lugs Q6.
Mounted within a rectangular portion B' 65
of the shell B, the body of which is cylin-
drical at all other points, is a wind gate S,
to the upper free swinging end of which a
cord or wire S' is fastened which passes
over pulleys S2 and S3 within the shell, 70
thence over a pulley S4, and winds about a
pulley S5, shown in Fig. 3, upon the con-
trolling shaft Ss. Hand wheels S7 are fas-
tened to each end of said shaft S6 and a
second pulley S8 is fastened to said shaft and 75
about which a cord or chain S9 passes, which
also passes about a pulley S' and is fastened
to the movable frame T, which latter com-
prises two oppositely disposed vertical rods
movable through the eyes T' upon the stand- 80
ard E and the lower rectangular end of said
frame T has a weight T2 fastened to the
frame by means of a chain T3. A suitable
seat W, adjustably held in the standard W',
is mounted upon the circular platform N 85
and upon which the operator is adapted to
sit when controlling the apparatus.
The operation of the apparatus will be as
follows: When it is desired to elevate the
apparatus, the propeller is set in motion by 90
the engine and a suction formed by the rapid
rotary movement of the propeller, causing
the air to be forced through the shell B, the
gate S being closed or nearly so and in which
position it will be disposed at an inclination 95
and cause a draft to be diverted up through
the shell D and against the parachute which
acts as an aeroplane. When the desired
height is attained, the operator, by causing
the gate to be thrown down toward a hori- 100
