B. l. BONGARTZL AVIAIORS INSTRUCTION MACHINE. APPLICATION FILED JULY 319I7.

I 2272,766@ Patented July 16, 191@l J 2 SHEETS-SHEET I.

I :Il 16%@ l? 18T]- i3 INVENTOR ATTORNEY a bicycle and ifdesired the ailerons may be `he has ladvanced sufficiently far, all of the Wheels are elevated with the exception of the single central wheel 15 and now the student learns to simultaneously control the fore and aft and the lateral balance as well as the directional steering of the machine by means of the vertical rudder, the steering wheel 14 being now out of contact iivith the ground.

By means of the construction and arrangement hereinabove described, the studentI aviator acquires vthe controls` gradually, one at a time, and thus acquires confidence in his ability'to handle an aeroplane andf'this is accomplished With absolute safety to the student and also Without the many mishaps and partial or total destruction of an aeroplane when the latter' is used for instruction purposes.

n lieu of the supporting wheels hereinabove described, floats, pontoons, or the like may be substituted for said wheels and made practically adjustable for the purpose hereinabove described in connection with the wheels, thereby enabling the student aviator to acquire all of the controls of the machine While skimming along the surface of the water and without rising therefrom. The floats or pontoons referred to are designated at 13, 14,15 and 16( corresponding with the respective wheels 13, 14, 15 and 16.

I claim :f-

l. An aviators instruction machine, comprisin a body, an engineffdriven propeller, intera? balancing means, fore and aftv balancing means, steering means, and supporting base elements, certain of which are adapted to be raised and lowered with respect to the body of the machine and thc surface on which the machine is being operated, said supporting base elements comprising a plurality of members arranged in a central fore and aft line with relation to the bodyof the machine, and means for independently adjusting the last named elcments up and down, for the purpose speci- 2. An aviators instructionmachine, comprising a body, any engine driven propeller, a horizontal rudder, a vertical rudder, lateral balancing surfaces, manually "controlled means for operating said vertical rudder, horizontal rudder. and lateral balancing surfaces, supporting base elements, certain of hich a're adapted to be raised and lowered with respect to the body of the machine and the surface on which the machine is being operated, said support-ing base elements coinprising a plurality of members arranged in a central fore and aft line with relation to the body of the machine and means for independently adjusting the last named elements up and down, for the purpose specified.

'jAn aviators instruction machine, comprising a body, an engine driven propeller, a horizontal rudder, a vertical rudder, lateral balancing surfaces, manually controlled means for operating said vertical rudder,

horizontal rudder and lateral balancing surfaces, and supporting base elements, certain of which are adapted to be raised and lowered with respect to the body of the machine and the surface on which the machine is being operated, said supporting base elements comprising one or1 more memlrs located in line with the fore and aft axis of the body, and other elements located atopposite sides of the body and equi-distan'tly-y from the longitudinal axis thereof, each of said elements bein independently adjustable up and down, or the purpose specified.

4. An 'aviators instruction machine, comprising a body, an engine driven propeller, a horizontal rudder, a vertical rudder, lateral balancing surfaces, manually controlled means for operating said vertical rudder, horizontal rudder and lateral balancing surfaces, and-supporting base elements, certainy of which are adapted to be raised and lowered with respect to the body of the inachine and the surface on which the machine is being operated, one of said supporting base elements being mounted for steering movement. i i

5. An aviators instruction machin', comprisinga body, an engine driven propeller,

a horizontal rudder, a vertical rudder, lateral balancing surfaces, manually controlled means for operating said lverticalA rudder, horizontal rudder and lateral balancing surfaces, and supporting base elements, certain of which are adapted to be raised and .loW-'y cred with respect to the body of the machine andthe surface on which the machine` is being operated, one of said supporting base elements being mountedk for steering movement and being controlled by the same ipeans used for controlling the vertical vrudi, er.

In testimony whereof I affix my signature.
