GEORGE COLEMAN BROWN, OF DALLAS, TEXAS.
HEAVIER-THAN-AIR AIRSHIP.Specification of Letters Patent.
1,315,084.
Patented Sept. 2,1919.
Application li February 27; 1918. - Serial'No. 21;&466.
T1 all whom it may concern:
Be it; known that I, GEoR'E 'COLEMAN
B'uowN, a citizen of the United States, re-
siding at Dallas; in the county' f Dallas and
5 State of Texas, have 'invented a'netw r and
'useful Heavier'Than-Air Airship;of which
the following is a specification.
My invention is' a'heavier-than-air'airship
and t method of :operating, producing' an
10 airship which may be operated to ascend and
descend and go forward, and to be turned'in
any desired direction. -The 'invention 'con-
sists in the combinationbf'a holloww "elon-
gated plane, filled with'gas; a car, arid four
15 cables, of ,which two 'are shorter= than'the
other two, the parts being: arranged so' that
they may be operated by a' new'method to
fly upward and forward, arid'ori a lever'and
forward, and downward and'forward, and
20 be turned in any desired direction, 'as here-
inafter specified.
The invention also' coilsists 6f dertaih parts
and details and combinations arid' Piethods
of operation of the same;'which will 'be hete-
25 inafter :described and claimed.
'Reference- is to be had to the accompany-
lug 'drawings formiiig'a 'part of this specifi-
cation, in which similar 'characters of ref-
erence indicate corresponding parts in the
30 three views.'
Figure 1 is a side view 'of the'airship; and
Fig. 2 is a vertical section;'arnd
Fig. 3 is-a plan view of the car.
The 'hollow elongated plane 'A which' is
35 filled with gas, is' placed'above the' car at an
incline in relation to' same;'the' front end be-
ing put lower than the 'rear end thereof, 'and
the' two'shorter cables Gand 8 are attached
above to the lower front''en'd of' the' plane,
40 and the two longer cables 7 and '9' are' at-
tached :above) to the higher'orear end'of the
plane, and the 'cables are=extended' iivard
and''downward from the ernds''arid sides 'Of
the' lane at acute 'anigles' thereto, 'aid atre
45 attached' below' to the 'operating cranks'10 on
the 'caPrB, 'which with its 'oqriipmett' and"load
is heavier than' the ascensive power of' the
gas with which the plane is charged.
The 'foregoing 'arrangements'of the parts
50 are all entirely new -and I' Maim' the 'sane
broadly but I shall state that thus far by mny
experiments and investigations that I have
found that' for the best resilts thelength of
the plane should be 5 or more times its
55 breadth, that the plane should'be phlced at 'an
incline of approximately 5 to 15 degrees;thatthec ables should' be"ht'iiiwatd' fi'om the
ends of the plane at angles of approximately
45'degtees and- inwad from' the sides'at
angles'of approximately 5 degrees, and that 00
'the car' 'houIld'be attachedto' the cables at
points apart where 'the; bables1'conveige to
points' equaling approtiiiately i to y of the
length 'Of the plane,k1nd that' the' plane'be
niade with rounded otp6inted Bifds to' facili- 65
tate its,'going' forward through the air 'and
.ouided upper' surf ace'to facilitate its 'tis-
ing when the cables arereleased and'with a
'flat or arched'nether ,sui'face' so' thatit will
"press e'ffebtively"'against the air when piled 70
against the , same,'arid wheels ' e 'at-
'tachled to{the bottom of the car to facilitate
'its' asdefding '4ff ground anid also to facili-
tate its 'aighting,and a'siuitable motor acid
appai'atus is to be employed' to operate' the 75
cables, but sudh' 'ibtor and apphtatus' is sep-
arate and' apart' front this invention.
The.airship' thus'construited is 'operated
to' ascendarid go' forwaird through the air by
fist operating the cable 6,' by' tfiiing' the 80
operating'crarik 10 to which it:is attached,
'and'then likewise operating the cable' 7,' and
then' the.'cable' 8, 'arid' then' the cable '9,'With
sfffficient n-a4idity, aid' continuin'gto so op-
erate them 'until the= aiiship reachesthe de- 85
sirdd' 'height,"andthen- the airship is made
to remain t the saflne'height andfto"go'for-
War'd by continuing to so operate' the 'cables,
with insufficient' rapidity to cause'it' to as-
cend, but with"snfficient =rapidityLto' prevent 90
it fibm descendingi.
'The cables may also beoperate4 in pairs,
first the two, front cables' 6 and'8,hoth'at one
tinie,- ind then the two rear ,cables'7'and 9,
both at de' time, bntbetter"resuilts' are Ob- 95
taiiidVby operating separately'as per the
foregoing as Oscillation is prevented,'anid too
the cables' being' put inward from the sides
of the plane prevent oscillation.
The cratiks 10,when operated; ate' turned 100
a whole'revolution pulling the plane"against
the airon the"first half of the revolution Lind
perinittin'g it toascend relative to the ciaik
onthe second half 6f the'revolution so that
it 'iay rise td its=positiOn above the car. The 105
airship 'is' tried'to' the' right. by'operating
the two' cables 6' a'd'7 #ith'ii'ore' rapidity
than the two cables 8: and'9; nd: is tutied to
the lfr by operating the twocables 8 and 9
with more rapidity than the two cables 6 110
