APPARATUS. FOR AERIAL PROPULSION.
Specification of Letters Patent.
Application filed July 23, 1909.
Patented Aug. 29, 1911. Serial No. 509,189.
To all whom it may concern."
Be it known that I, FRIEDRICH LUDWIG BARTELT, of Corston Lodge, near Bristol, England, gentleman, have invented new and useful Improvements in Apparatus for Aerial Propulsion, of which the following is a specification.
The object of the present invention is to provide an improved machine which will propel itself and its occupant or occupants in the air.
My invention is applicable to machines which are provided with air surfaces arranged to move up and down in a circular path (under the impulse of a motor carried by the machine) with the object of sustaining and propelling the machine in the air.
According to my invention I employ a frame covered with canvas or other suitable material and above this again one or more similar covered frames. The covering of the frames is arranged with pockets in such a way that these will belly out with the air as the frames are moved in a given direction and will flatten out when they are moved in a contrary direction. The frames are carried at the ends of cranks by which a parallel motion in a rotary path is imparted to them and the timing of the cranks is such that when one of the frames is moved upward its neighbor is moved downward so that they alternately approach and depart from one another to the fullest extent permissible. Rotation is imparted to the cranks by the motor by chains or other suitable gearing.
The road wheels will generally be useful in starting and moving the apparatus about, but as soon as the covered frames are able to act efliciently on the air, the wheels will cease to be driven and the machine will be lifted and propelled by the frame alone.
The steering of the apparatus in the air may be effected by means of a sail or by a propeller driven by the motor.
In the accompanying drawing I have shown a portion of a flying machine embodying my present improvements.
Figure l is a side elevation, Fig. 2 is a front view, and Fig. 3 is a perspective view of a detail hereinafter mentioned.
Upon a carriage or base represented by the straight line a is mounted a motor engine of any suitable kind and seats for passengers neither of which are shown. The base also supports a framing b constructed as lightly as possible, preferably of metal tubing. This framing b carries bearings for crank shafts 0 and (Z and also bearings for the shaft e which is driven by the motor and which imparts rotation by means of chains and sprocket wheels to the crank shafts 0 and d above mentioned. The crank shafts 0 and cl are arranged in pairs as shown in Fig. 2. The shafts 0 are situated at the right hand end of the machine as seen at Fig. 1 and the shafts d at the opposite end. Each pair of shafts work one end of a pair of frames 9 and h by means of oppositely placed cranks z and j, is and Z. The upper frame 9 has pendent rods m and n jointed to the cranks 11 and iv and the lower frame 72. has supporting rods 0 and p jointed to the cranks y and Z. The frames 9 and h which act as propellers for the machine are covered with canvas or similar material arranged to swell out in pockets 9 when moved by the cranks in a downward direction in order to create a temporary strong resistance. The pockets 9 are not permitted to swell out in the opposite direction and to this end an underlying network .9 or longitudinal wires or their equivalent are provided as clearly seen in Fig. 3 of the drawings.
1', r are merely stays for increasing the rigidity of the frames 9 and h.
It will be seen that as the crank shafts 0 i and d rotate the frames 9 and h are moved by the cranks i j and 70 Z in circular paths in such a way that each acts alternately as a propeller giving by the downward and backward stroke while the pockets are inflated a forward motion to the apparatus. The drawn position shown in Fig. 1 gives the frame it at the moment of completing its downward and backward stroke while the frame 9 is on the point of completing its upward or inoperative stroke. It will be observed that the pockets 9 of the frame [L are distended while those of the frame 9 are not so. The dotted positions of Fig. l are those assumed by the frames 9 and h at the opposite ends of their strokes.
In the apparatus above described only one pair of propelling frames are provided. It will be understood however that a greater number may be employed if desired.
By means of alternately operating propelling frames provided with pockets a sufficient resistance of the air may be created to enable the apparatus to progress independently of the air currents the resistance of which is usually relied upon to sustain aeroplanes.
No attempt has been made to illustrate steering mechanism which may be of the rudder type with or without a propelling device or fan of the kind already adopted.
In the hereinbefore described apparatus there is a double arrangement of cranks; that is to say the frames 9 and h are worked from both sides. If preferred however a single set mounted centrally may be employed and the said frames 9 and h may be provided with central apertures for the; cranks to work through.
What I claim as my invention and desire to secure by Letters Patent is:
Apparatus for aerial propulsion comprising parallel superposed frames provided with collapsible air pockets, means for moving said frames in independent rotary paths and operating means for the frames arranged and timed so that the frames alternately approach and recede from one another, while retaining their parallelism, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FRIEDRIGH LUDWIG BARTELT.
