This invention is concerned with the provision
of an aircraft launching means, whereby, military
tral column 8 with radial arms 3' extended out
or civilian aircraft may be launched from secluded
gence as to each other to aid in the balancing of
nooks about cities, islands, forests, on waterways
and vessels et cetera, and wherein the theory of
performance is that oi night theory, wherein, the
forces of gravity during flight are overcome with
the assistance of hydraulic pressure, plus power
derived from self propelled aircraft, as in night.

ings there is shown a three arm structure this may

as the balancing functions are maintained.
As the tubular piston is traveling thru its upper
stroke it is desired that same be rotated to convey
10 momentum to the aircraft carried thereby thru
means hereinafter described, to this end there is
centrally disposed within said tubular piston l, a
spiral member l u which is in fixed engagement at
its lower end with the base at l l, and maintained
carrying a radial superstructure, hydraulic means 15 in free central relation to said piston, at its upper
end, by a bushing l2. Rotary movement is effect
ed to said piston thru the agency of a spiral by
co-operative means in the form of spring actuated
for raising, lowering and rotating said piston and
superstructure, load carrying arms, arranged for
automatic angular adjustment in conformity to
the slope of said base bank, carried by said super
structure, automatic means for leveling said arms
when piston and superstructure is raised to a
height, means for releasing aircraft from the said
arms when same are leveled, and means for the
lowering of said piston.
This invention resides substantially in the com
bination, construction, arrangement and relative
location of parts, all in accordance with this dis
closure.
In the accompanying drawings
Figure 1 is a vertical sectional View of an air
craft launching means in accordance with this in

Figure 2 is a fragmentary section substantially
plungers M housed within said piston, extended
inward therefrom, and engaged with said spiral
so that as hydraulic pressure is exerted to the
piston to raise same, said plungers are forced to
follow the spiral -path of the member ll! causing
said piston to rotate during travel thereof. Said
' plungers are of a structure, as shown in Figure 3,
permitting free rotation forward so as to allow self
propelled aircraft having excelled forward thrust
to enable build up forward speed free from spiral
engagement.
