CARL ALFRED JOHANSSON, OF CHRISTIANIA, NORWAY.
STABILIZATION 0F AIRCRAFT.
Specification of Letters Patent.
Patented Aug. 6, 1918.
Original application filed January 18,1916, Serial No. 72,759. (Now Patent No. 1,223,698.) Divided and this application filed February 12, 1917. Serial No. 148,297.
To all whom it may concern:
Be it known that I, CARL ALFRED JOHANS- son, residing in the city of Christiania, Norway, a subject of the King of Norway, have invented certain new and useful Improvements in Stabilization of Aircraft, of which the following is a specification.
My invention relates to an improved stabilization device for air-crafts.
The invention is distinguished by the feature, that the carrying or bearing plane is connected to the machine frame in such a manner that the aft-end of the plane can move to both sides and at the same time be lowered;
The invention is explained on the appended drawing, in which is shown diagrammatically the principal parts of a flying machine, Figure 1 is an end-view from be hind, and Fig. 2 is a top-view.
Said figures are identical with certain figures in my Patent No. 1,223,698, dated April 24, 1917.
The carrying or bearing plane 1 is connected to the machine frame at the front by a universal joint of any known type and at the back by a cross-guide consisting of a T-piece 2 secured to the bearing plane, said T-piece having a bi-partite horizontal guide-slot 4, the parts of which meet at an obtuse angle, and a vertical guide-slot 3 engaging studs 5, 6 on the machine frame. By the arrangement of a crossguide the bearing plane will by a side movement not only be tilted, see Fig. 1, but the rear-end of the plane will also be moved to the side, see dotted lines in Fig. 2, and thereby present to that side the largest bearing surface, and it is also lowered slightly at the back so that the front edge will cut the air at an angle to make the air-pressure lift the plane. The arrangement of the crossguide has the advantage that the double engagement of the two studs will steady the movements of the machine and of the plane, which cannot be obtained with a single connecting link.
The bearing plane and the T-guide are shown in their preferred V-shaped form, but it should be understood that they may be straight as well and yet work in the described manner.
What I claim is:
A stabilizer for air craft of the character described, comprising in' combination, a carrying plane, adapted to be connected to the front of the air craft frame, a crossguide connecting said plane to the rear of said frame, consisting of a T-piece secured to said plane and provided with a vertical and a bi-partite horizontal guide slot, the parts of which meet at an obtuse angle, studs on the air craft frame adapted to travel in saidslots for allowing a lateral tilting of the plane and a movement of its rear end toward one side, so as to present to that side the largest bearing surface and for allowing it to be slightly lowered at the back so that the front edge will cut the air at an angle for making the air pressure lift the plane substantially as described and for the purpose set forth.
In testimony whereof I aflix my signature in presence of two witnesses.
CARL ALFRED J OHANSSON.
