Application May 7, 1945, Serial No. 592,471 4 Claims. (Cl. 244-63l l 2 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. load carrying mechanism, and while in the draw ings there is shown a three arm structure this may Broadly it is an object of this invention to pro vide a launching means for aircraft which con sists generally of a circular banked base, a verti cal column centrally disposed within said base, a piston operative within said column, said piston ward therefrom, said arms having spaced diver be increased or decreased to any number so long 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 vention. 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. Load carrying mechanism co-operating with the above defined structure includes load carry ing arms l5 positioned below and in a vertical plane to the radial arms 8’ and in pivotal engage on the line 2--2 Figure 1. ment with the member l5 for vertical circular Figure 3 is a fragmentary section substantially 35 movement thereof to effect angular or horizontal on the line 3_3 Figure 1. carriage thereby, said member l5 being freely car Figure 4 is a semi-vertical section of a modified ried upon the outer periphery of the column 5 form of this invention. i rotatable to enable said load carrying arms l5 to Figure 5 is a fragmentary section on line 5_5 rotate in unison with the superstructure and Figure 4. 40 radial arms thru means of cable and pulley Figure 6 is a vertical sectional View of another mechanism comprising a cable Il, carried upon modified form of this invention. pulley wheel I8 of twin pulley I9, wheel 2l! thereof The true nature and manner of use of an air being in free travel engagement upon said radial craft launching means in accordance with this in arms for positioning thereon, said cable being vention will «be best understood -by a detailed de hooked at one end thereof to the load carrying scription of the form thereof shown in the draw arms as indicated at 22 the other end in hooked ings in an illustrative sense. engagement with the lateral web portions of mem This launching means includes a circular base ber l5. member 2 having banked or sloped sides 3, to give In the use of this launching means the aircraft desired tilt to aircraft for a whirling take off, and is rolled over a tramway or by any other suitable a flat central portion 4 Within which is a fixed means placed upon the banked base and the load centrally disposed vertical column 5 having at its carrying arms releasably hooked thereto.
