Application fled February Be it known that I, STANLEY M. Tnarmn,

a citizen of the United States, and a resident-'- of Petersburg, in the county ,of Dinwiddie, State of VIrginia', have invented certain new and useful Improvements in Toy Aeroplanes, of which the following is a full and clear specification, reference being had to device swun I from an overhead support; I

Fig. 2 a detail vertical sectional View of the swivelcontact member; Fig. 3 a perspective view of the suspending hook attached to the electric cable; and Fig. 4 a side elevation of the accompanying drawings, in which- Figure 1 is.aside elevation showing my a portion of the aeroplane. Fig.5isadetail plan view showing the manner of adjusting a the rudder;

The object of this invention is to provide a simple electrical aerial toy ,ofthe aero-, lane or dirigible air ship type, .as more lly hereinafter set forth.

In the drawing a designates a miniature 2 aeroplane of a well known type provided at I with the usual planes 0.

illustrated is the Bleriot tybe but it will' be.

its rear with an adjustable rudder and also The aeroplane understood that any other; type of aeroplane may be employed or any'form of balloon or dirigible. air ship. I

At the forward end of the air ship is affixed an electric motor (Z which isjtdapted to rotate a propeller 6. Electrical connection to the motor is made through the socket f ofordinary construction, which is attached to the terminals of the motor, and which is adapted to receive an ordinary electrical plug 9 attached to the lower extremity of an electric cable It, composed of two wires adapted to carry the current to and from the motor. The plug g is detachable from the socket f in'the usual'manner in order thatthe air ship may be disconnected from the cable.

The cable h is suitably attached at its upper end to an overhead support such as a ceiling of a room, and hangs freel therefrom, thus supporting the weight 0 the air ship. To prevent the weight of the air ship from disconnecting the plug 'g from its socket and to insure an evenly balanced suspension, I attach to the cable h, at a distance above the plug g, a hook i, which is adapted to be engaged. in an eye 7' projecting upwardly from a li ht frameVc attached to t body of the air 'p at its forward end.

11912. nac'zamaq The means for attaching the upper end of the cable to: the overhead support consists of a swivel contact coupling consisting of a pair of cylindrical blocksl ofinsulation ma-.

terial, theseblocks being notatably attached together, one abovetheother, by a, vertical I connecting bolt or-pin m. The two wires or conductors ofthe. cable h are separated at ,the upper end of the cable and connected to the lower .block' at opposite sides thereof,

One of these conductors is electrically con: t

nected by means of a metal plate 1 with the f lower end ofthe bolt m, and the othercon-f ductor is electrically connected to-a vertical contact finger 0 whose upper free end bears resiliently upon an annular band of metal p attached'tothe upper block. Theband p s electricall connected to a conductor attached to t e'upper block,'an'd the centraii bolt m is attached tofanothe'r conductorq',-

these two cond'uctors'g, '9 being eirtend'ed to a suitable .point or place, where they'are connected to a battery of suitable strength and character,

It will be observed that when the current is sent through .the motor, the propeller will cause the miniature air' shi to move'for wardly, and thefair ship-beingjtethered by the y sus ending cable and the. suspending cable bemg free, theair ship will be caused to move in a circle, and the centrifugal force will cause the air ship to rise higher and higher as the speed increases; the tendency being to swing the cable toward the horizontal. To prevent the twisting of the cable interferingwith thei free movement of the device, I provide the swivel "coupling above described and locate the same at the upper end ofthe suspendin cable. The operation ofthis coupling is o vious;-it

tical pivot rod b' and adjustment of the rud-v der is secured in any suitable manner, preferably by means ofa cordloop b? which loop will be made sufliciently taut to frictionally hold the rudder in its adjusted position. By

, ermits free rotation of .the depending ca le without means of this rudder the circles described by the air ship in its flight maybe made larger or smaller, as is obvious.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is

1. In a device of the character set forth, a miniature air ship of suitable type, an electric motor thereon connected to a propeller, an electrical suspending cable adapted at its lower end to be detachably connected to the motor and at its upper end to an overhead support, and a suspending hook attached to the cable near its lower end and means for detachablyconnecting this hook to the air ship frame thereby relieving the detachable connection from strain.

2. In a toy of the class set forth, a miniature air-ship of suitable type carrying an electric motor and a propeller, and means for suspending the airship and supplying current to the motor consisting of a twowire suspending cable adapted at its lower end to be connected to the motor, a pendant swivel attached to p the upper end of the cable and consisting of a pair of blocks arranged one under the other and means for swivelly connecting the blocks, means for suspending the upper block from an overhead support, and contact devices adapted to carry the current across the swivelly connected blocks.

3. In a toy of the class set forth, a miniature airship of suitable type carrying an electric motor and a propeller, and means for suspending the airship and supplying current to the motor consisting of a twowire suspending cable adapted at its lower end to be connected to the motor, a pendant swivel attached to the upper end of the cable, a bail for suspending the swivel from an overhead support, contacts carrying the STANLEY M.
