Abstract
212,626. Ottino, G. P. Dec. 12, 1922. Machines supported by rotary propellers; propelling; steering; planes, arrangement of.- A machine is supported by Hades carried in pairs upon pairs of vertical endless cables, steel bands, or chains in such a manner that the blades are separate and substantially horizontal during the down stroke, and approach one another and become vertical for the upstroke. Figs. 1 and 2 show a machine in which blades o are carried by spindles q passing through sleeves r, rigidly secured to cables n passing around pulleys m. The front ends of the spindles q are fixed to pairs of levers s, s<1> stop jointed at u. The pulleys m are notched to engage reduced portions r<1> of the sleeves r, the levers s, s<1> moving from the horizontal position to the vertical and vice versa as the sleeves r pass around the pulleys. To prevent the pairs of levers s, s<1> from fouling one another during the upward and downward strokes, their outer ends have bosses moving within sockets in the sleeves r and provided with peripheral cam grooves engaged by pins in the sleeves r so that the levers s, s<1> move into different planes as they open and close. The pulleys m are mounted on shafts p, the lower pair of shafts being driven by bevel gearing and the shafts j, k from an engine i which also drives a screw propeller l. A rudder h and elevator h<1> are arranged as shown. Fig. 7 shows a plan of a modification in which fore and aft series of blades o are carried by eight endless cables, the driving-shafts p converging towards the front and rear of the machine. The levers s, s<1> in this modification are mounted on squared ends on the shafts g and are held against the inclined surfaces of bosses v<1> secured to sleeves fast on the chains. The inclination of the driving-shafts and of the surfaces of the bosses v<1> ensures that the levers s, s<1> ascend and descend in different planes. The blades o are set at' a slight angle to their shafts q so as to prevent an angle of incidence on the down stroke to give additional lift during forward motion of the machine. This inclination also diminishes resistance to forward flight on the upstroke, the blades assuming the positions shown. Lifting planes hinged to enable them to be extended transversely for forward flight are provided between the front and rear blade systems on lateral extensions of the frames so as to be clear of a centrally arranged propeller. Arched plates forming shields for the blades o in their uppermost positions are provided on the top of the framework. Specifications 6378/09 is referred to.
