WILLIAM 1.. WEST AND JAMES F. weer-,0! BELMONT, NORTH CAROLINA,

ron Ami-cumin The present invention relates to toy aeroplanes and has for itsprincipal ob ect to provide a captive plane pivotally supported at one end of a weighted arm and mounting the arm for rotative movement intermediate its ends whereby to provide for the movement of the aeroplane in a circle upon the operation thereof.

A further object of the invention is.to provide an electric motor within the body of the aeroplane for driving the propeller thereof and operatively connecting the motor to circuit wires extending through the arm and support therefor, whereby to provide for the operation of an aeroplane.

An additional object is to provide a device of this character of a simple and practical construction which is neat and attractive in appearance, strong and durable, and

relatively inexpensive to manufacture and maintain. in operation, and otherwise well adapted to the purposes for which the same is intended.

Other objects and advantages reside in the special construction and combination of the'various elements comprising the invention, reference being had to the accompanytric motor therein, and

7 is arranged a standard 9 of tubular formation having each end opened and progure'5 is a fragmentary longitu'dinal 'sectional view through the contact member carried bv the weighted arm;

- Referring now to the drawlng in detail,

wherein for the purpose of illustration we have shown a preferred embodiment of our invention, the numeral 5 designates a track. upon whichthe aeroplane 6 is adapted to.

into a position "for being of an annular travel while arisin flight, the said trac formation and provided with a base 7 conpentrically disposed with res ect thereto, and connected with the track y means of radially extending braces 8. Upon the base vided at its upper end with a cap 10.having a reduced lower portion 11 inserted within Application filed Kay 21, 1928. Serial No. 279,430.

the upper end of the standard, and an annular shoulder 12 formed on said cap adapted to seat upon the upper edge of said standard. The cap 10 is fitted upon' 'the standard with sufficient freedom to permit the free rotation of the cap thereon.

The upper portion ofthe cap is bifurcated as shown at 13 and between the sections thereof is arranged a pin 14: providing a pivotal mounting for an arm 15, with its ends extending outwardly at o posite sides of the standard. One end of tlie arm 15 is pivotally supported on a pin 16 extending between the bifurcated end 17 of an attaching member 18, to which an aeroplane of conventional construction, indicated at 19, is suspended. Within the body or fuselage of the aeroplane is mounted an electric motor 20 having its shaft extending forwardly through the front end of the body of the aeroplane and having a propelller 21 mounted thereon. The motor 20 is connected by circuit wires 22 leading through the arm l5to a point adjacent its pivotal mounting, the wire 22 then extending outwardly through the arms for connection with a brush 23. The wire 22 and brush 23 are suitably insulated from the arm, ,as is I shown at 24. Upon the standard adjacent the upper end thereof is mounted a collar 25, having a sectionof insulation material 26, interposed between the collar and the standard, said collar having'a circuit wire 27 attached thereto and extending through the wall of the standard and downwardly therethrough and outwardly atthe lower suitable source of power.

The wire 27 bus constitutes a feed-wire 5 5 through the collar'25 and brush 23, which for. the motor, being connected therewith communicates with the motor through the wire 22, for supplying currentthereto, the motor being grounded, to the supporting member 18, arm. 15. and standard 9. The end of-the arm 15, opposite from the aero end of the standard for connection with a plane is threaded, asshown at 28, and upon which threaded end is threadably mounted a weight. 29, o crating as a counter-balance forthe aerop ane. j'

It. will be apparent from the fore oing that the supplying of current "throng the wire. 27, the motor of the aeroplane: will be operated, so as to drive the. propeller, and

throu h its rotation, the, aeroplane .will be move ina manner well known in the art.

" Through thepivotal mounting of the arm collar 23 and 25 re 15, 'the aeroplane will be enabled to travel in a circuit direction around the track 5,

the current being continuously supplied for operating themotor throng the brush and ective y. adjusting the weig aeroplane will be permitted to rise above the ceptible of various chan es and modifica-- surface of the rack as the momentum thereof increases, and thus the toy aeroplane will simulate an actual aeroplane in flight.

It is obvious that the invention is sustions, without departing rom the spirit or scope ofthe invention or sacrificing any of its advantages, and we accordin ly claim all such forms of the device to which we are entitled.

Having thus described our invention, what By properly t 23 on the arm, the f ard rising from the base, a cap rotatabl 25 mounted on the u er end of said standar and an arm pivota y supported intermediate its ends on said cap, a toy aeroplane pivotally attached to one end of the arm for rest upon said track, counter-balancing means or the aeroplane adjustably arranged at the opposite end of the arm, and operating means for the aeroplane comprising an electric motor mounted therein, and operatively connected with the propeller of the aeroplane, a brush carried by the arm adjacent 'its pivotal connection, a collar mounted on the standard adjacent its upper end in contacting relation with said brush, said brush and said collar being insulated respectively 40 from the arm and the standard, a circuit wire connecting said collar with a source of supply, and a circuit wire connecting said brush with said motor.

In testimony whereof we aflix our signatures.
