Abstract

Abstract A fractional horse power motor in a toy aircraft has slack conductive wires therefrom connected to opposite ends of the crossarm of a pivotally mounted bellcrank with its short arm connected to control the elevator. From the crossarm the wires extend for operative distance to a handle, including a switch and thence to a battery housed in a case having a shoulder strap. A single operator needs only to hold the handle and to carry the power source, as a battery, at which the wires terminate; thus pressing the switch drives the engine and manipulating the wires for bellcrank movement controls flight elevation.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 293 words
A controllable toy aircraft self-propelled by a fractional horsepower electric motor disposed forwardly in the fuselage of the aircraft and including bow blade means, transmission means interposed between the motor and said blade means to transmit motor drive thereto, transversely extending elevator means parallel with, and rearwardly of, the aircraft horizontal stabilizer and hingedly connected thereto, a single central short arm bellcrank rearwardly of said motor and substantially amidship the fuselage, pivot means upstanding from the fuselage to mount said bellcrank at its axes intersection to extend normally in horizontal plane and with the short arm axis normally transverse the fuselage, a rigid member with ends pivotally connected, respectively, to the free end of said short arm and passing through an opening in the fuselage outwardly to the elevator at a spaced distance from the hinge connections, conductor means including a pair of flexible electrical conductive wires extending continuously within the fuselage from said motor with slack and connected to the respective longitudinally spaced apart ends of the bellcrank crossarm, and thence extending outwardly from the aircraft to be manipulated by an operator, a storage battery as the source of electrical power to which said conductor means are connected, a case therefor, a shoulder strap on the case for carriage by the operator, a handle to which said wires extending from said aircraft are mechanically connected and to which at least one of same is electrically connected, said conductor means including electric wires extending sufficiently between said handle and battery to provide slack therebetween when the device is in use, said short arm axis swinging back and forth, fore and aft of a substantially amidship transverse axis to move said rigid member in elevator adjustment responsive to operator manipulation of said conductive wires.
Claim 2
Dependent Claim 293 words
A controllable toy aircraft self-propelled by a fractional horsepower electric motor disposed forwardly in the fuselage of the aircraft and including bow blade means, transmission means interposed between the motor and said blade means to transmit motor drive thereto, transversely extending elevator means parallel with, and rearwardly of, the aircraft horizontal stabilizer and hingedly connected thereto, a single central short arm bellcrank rearwardly of said motor and substantially amidship the fuselage, pivot means upstanding from the fuselage to mount said bellcrank at its axes intersection to extend normally in horizontal plane and with the short arm axis normally transverse the fuselage, a rigid member with ends pivotally connected, respectively, to the free end of said short arm and passing through an opening in the fuselage outwardly to the elevator at a spaced distance from the hinge connections, conductor means including a pair of flexible electrical conductive wires extending continuously within the fuselage from said motor with slack and connected to the respective longitudinally spaced apart ends of the bellcrank crossarm, and thence extending outwardly from the aircraft to be manipulated by an operator, a storage battery as the source of electrical power to which said conductor means are connected, a case therefor, a shoulder strap on the case for carriage by the operator, a handle to which said wires extending from said aircraft are mechanically connected and to which at least one of same is electrically connected, said conductor means including electric wires extending sufficiently between said handle and battery to provide slack therebetween when the device is in use, said short arm axis swinging back and forth, fore and aft of a substantially amidship transverse axis to move said rigid member in elevator adjustment responsive to operator manipulation of said conductive wires.
Claim 3
Dependent Claim 39 words
A toy aircraft as claimed in claim 1 in which said handle includes a hand grasp and projections transversely from the ends of the hand grasp at which said wires extending from said aircraft are connected, respectively, as aforesaid.
Claim 4
Dependent Claim 67 words
A toy aircraft as claimed in claim 1 in which said handle mounts a reel at each end thereof on which the respective wires extending from said aircraft and connected to said handle may be wound, said reels including a lever handle and means connecting said reels to be turned together, thus to roll up the wires to facilitate taking up the aircraft for transport, and storage.
Claim 5
Dependent Claim 45 words
A toy aircraft as claimed in claim 1 in which the slack in the respective wires between said motor and bellcrank is of greater lengths than the respective changes in distance between the points of connection to crossarm in furtherest left and furthest right positions.
Claim 6
Dependent Claim 37 words
A toy aircraft as claimed in claim 1 in which said connection between bellcrank and elevator comprises a rigid rod, the rear pivotal connection thereof being to a bracket provided on the underside of the horizontal stabilizer.
Claim 7
Dependent Claim 88 words
A toy aircraft as claimed in claim 1 in which said transmission means includes a drive shaft which is journaled forwardly in the nose of the craft and having the blade means mounted on the outer end thereof, and in which said drive shaft is journaled rearwardly in journal means mounted on a fuselage crossmember and has a gear on the rear end of the drive shaft to the rear of said crossmember, said motor having a pinion mounted on the shaft thereof and meshing with said gear.
Claim 8
Dependent Claim 32 words
A toy aircraft as claimed in claim 1 in which said handle includes a pushbutton type switch therein as a part of said conductor means, to close circuit from said storage battery.
