CAPTIVE FLYING-MACHINE OF THE HELICOPTER TYPE.
I Specification of Letters Patent. Patented Sept. 6, 1921.
Application filed March 9, 1920. Serial No. 364,606.
To all whom it may concern:
Be it known that I, WILHELM ZUROVEC, a citizen of the Czecho-Slovak- Republic, residing at Fischamend, near Vienna, German Austria, have invented certain new and useful Improvements in Captive Flying-Machines of the Helicopter Type, (for which I have filed an application in Austria February 6th, 1918,) of which the following is a specification.
This invention has for its object to provide an improved captive flying machine of the helicopter type, which is adapted to be secured by downwardly diverging ropes.
The invention consists in the carrying frame being made with three arms, so that the ropes are attached to the corners of a triangle, the carrying frame being thus held in all directions.
The invention further relates to a winch for the securing ropes, which allows of a together and also a relative shortening and lengthening of each separate rope.
In the accompanying drawing illustrating the invention Figure 1 is a side elevation and Fig. 2 a plan view;
In the constructional example shown, the arms of the carrying framework 1 inclose angles of 120 each, whereby the provision of resistance planes becomes unnecessary. The air screws 2 are above the carrying frame 1, two screws being fitted one above the other. Above the screws 2 the pilot basket 3 is fitted. 4: indicates the motor, while parts 5 are the compressed air shock-absorbers.
To the ends of the carrier arms 1 are attached the securing ropes 6, which are taken over suitable guide pulleys 7, 8 to a common winch 9.
This winch is fitted corresponding to the number of securing ropes 6 with three drums 10, 11, 12, the middle one 10 of which is fixed to the shaft 13, while the lateral drums 11 and 12 are mounted on the said shaft so as to be freely rotatable. The loosely rotating drums are connected by means of a coupling with the drum that is fixed to the shaft. The said coupling is such that when the spur' gear 18 is rotated by means of an air driven device, all the ropes are equally wound. The relative positions of the drums relatively to each other can however be corrected at any time if any relative changes of the length of the ropes are necessary.
, In the present case the coupling of the drums 10, 11,12 is effected by worm gearing one part of each gear being attached to a drum fixed to the shaft, the other part being attached to a drum freely rotatable on the shaft. For this purpose at each side of the middle drum 10 worms 14 and. 15 respectively are journaled, which engage with worm'wheels 16 and 17 respectively connected with the sides of the drums 11 and 12.
On the shaft 13 revolving, the drum 10 fixed to the said shaft is driven, and, by means of the worms 14, 15 fixed to it, drives the worm wheels 16, 17 and thereby the drums 11, 12 connected therewith.
WVhen the worms 14, 15 are carried around the axis of the shaft 13 in one direction or the other, the position of the drums 10, 11, 12 relative to one another and thereby the relative length of the separate securing ropes 6 may be altered at will.
What I claim is:
1. A captive flying machine of the helioopter type comprising in combination a frame having three arms arranged at angles of 120, ropes arranged in the form of a trapeze, and means for securing the upper ends of the ropes to the ends of the said arms, as set forth.
2. A captive flying machine of the helicopter type, comprising in combination a frame, ropes having their upper ends attached to said frame, and a winch having drums to which the lower ends of said ropes are attached and a worm and worm gear for coupling said drums together in any desired position, for the purpose, on the one hand, of permittinga simultaneous paying out or drawing down of all theropes, and onthe other hand, a relative shortening or lengthening of each separate rope.
3. A captive flying machine of the helicopter type, comprising in combination a frame, ropes having their upper ends attached to said frame and a winch having fixed and rotatable drums to which the lower ends of said ropes are attached, and a worm and worm gear for coupling said drums together in any desired position, one member of the said worm gear being attached to a fixed drum, and the other member thereof being attached to a rotatable drum, as set forth.
In testimony whereof I have signed-my name to this specification.
