TOY FLYING-MACHENE.

Specification of Letters patent.

Application filed January 17, 19M). Serial No. 538,355.

eilicient and durable; to provide for the ready renewal of the part-s; to provide for numerous adjustments in order to change the direction of' flight; and to attain cer tain other advantages hereinafter more fully appearing. y 1

The invention consists in the parts and in the yarrangements and combinations of parts hereinafter described and claimed. A

in the accompanying drawing' which forms part of this specification and 'wherein .like symbols' refer to like parts Wherever they occur, lFigure 1 is a perspective View of a toy flyingmachine constructed according to my invention; Fig. 2 is a fragment-ary view, partly in side elevation and partly -in longitudinal section, showing the preferred construction and arrangement ofthe hub portion for the propeller and connection with the motor element; Fig. 3 is a frag# .mentary edge view of a portion of the propeller; and Fig. i is a fragmentary View, partly in side elevation and partly in longitudinal section, showing the preferred form or arrangement for attaching the aeroplane to the body member. The device comprises an elongated body member, preferably a tube 1. The tube may be constructed of 'paper or any other light Weight material suitable for the purpose, which can be made suflicientlyrigid. On the opposite ends of the tube 1 are detachably secured bearing pieces or ferrules 2. The ferrules 2 are perforated centrally and have the axial stem portions 3 of the propellers insertedtherethrough. T he inner end portions of the axial members 3 areA hooked i looped and connected 'respectively to the g-posite'ends of atorsional spring, or prefbly, an elastic rubber band 4.

The propellers at the endsof the tube` each, comprise two oppositely disposed blades 5. The blades of one propeller are set at an angle or pitch in adirection opposite to that of` the blades of the opposite propeller, so that, as the two propellers are rotated in opposite directions, they act to propel the toy in one normal direction of Hight in line With the axis of the tube 1. The blades 5 are preferably composed of triangular sheets of thin paper orfother:

suitable material, which are secured along two sides to a Wire 6' which is bentangularly at its opposite ends.A 'lfhe-middlejportion.

of the Wire 6- is odset'as at 7 and clamped between the pinched or rolled end portions 8 of a substantially Vsha'pe hub pieceor member 9. This member Scomprises, preferably, a strip of sheet metal whichA is first folded longitudinally to constitute 'a 'channel which is substantially-.U-shape in cross section and then bent at its middle so that it assumes a substantially V shape with the side portions of the metal at the bend bulging outwardly as at 10. The sides of the end portions 8 are then pinched tightly. about the angular portions of the Wire 6 at the ends of the oifset portion 7.'

The axial stem members 3 are placed through a central perforation in the members 9v and have their outer ends hooked or looped about the middle of the offset portion k7 of the Wire frames 6. By this arrangement, the rubber band 4 which connects the inner ends ofthe axial stems 3, draws the llatented-Dec. 5, 1911i.

apen portions of themenbers 9 against the ferrules 2, whereby the parts are held intact' on the tube 1, yet permitting the removal of the ferrules 2 and Withdrawal of the stems I 3 from the tube so that the rubber band .4l

may be disconnected and replaced.

n'aeroplane 11 is mounted transversely of the body member or tube 1. Itcomprises a rectangular sheet of 'thin paper3 or other suitablematerial which is secured along its edges to vstrips 12. The aeroplane is prefer-v ably 'curved slightly upward on each side of the tube 1 and the middle` marginal portions on each sideof the aeroplane are cut-out or slotted as at 13 Wherebythe strips 12 are exposed. A rubber band 14 is looped over Y each of these exposed portions v12 so that the two .end loops 1-5 are drawn down on op- 4`fposite sides thereofunderneath the aeroplane. The tube 1 is placed through said l manner.

loops 16 ;and, b having the bands 14 small enough so that t ey have to b e stretched and placed under tension when thus applied, the aeroplane is held firmly in position. Ob` viously, however, in some'cases, a cord may `be substituted for the rubber band 14; and looped tightly about the parts in the same By this arrangement, the aeroplane is permitted to be shifted to dierent u positions endwise of the tube 1.A It also permits of readily removing the aeroplane from the tube and replacing 1t thereon.

Mounted on dthe tube .1 4is a balancing frame comprising a bail 16 whose end portions 17 are looped around the tube 1 sufiiciently tifght to hold in place, but permitf ting the rame to'be moved endwise of the tube. On the cross member 18 of the frame is slidably mounted a block 19.

In the o eration of the device, one of the propellers v1s held 'stationarily with the tube and the opposite propeller revolved, thereby twisting. the rubber band. After the rubber band has been sufficiently twisted, the toy 'is I released and the untwistinglof the rubber band will forcibly revolve the two propellers "in opposite directions and the toy will be thereby propelled. By adjusting the, aeroplane and balancing frame 'lengthwise of the tube 1 the toy' may be made to travellin a horizontal plane and at an upward and' downward inclination. Also, by tilting the aeroplane with respect to the balancing frame, the toy may be madeA to travel in a circle. Numerous adjustments may be effected by shifting the aeroplane or the balancing trame vand the sliding weight there on. So, too, the balancing frame may be dis,- pensed with in some cases; and, also, both the balancing frame and the aeroplane may be eliminated from the device, in which case the toy will iiy perpendicularly instead of horizontally. i

Obviously, the device admits of considerable modication without departing from,

l my invention. Therefore, I do not wish to be'limited rto the specific constructionand arrangement shown. l

What I claim as my invention anddesire to secure by Letters Patent is:

1. A toy fiyingsmachine Acomprising an elongated body member having a propeller at both of its ends, said propellers being oppositely rotatable but arranged and adapted to-propel the machine in one direction, an

4 aeroplane mounted transversely of said elon gatedbody member and adjustable lengthwise thereof, and a balancing trame dependj ing from saidbody member beneath said aeroplane and adjustable lengthwise ot said body member. i

2. A toy flying-machine comprising an elongated body member having a propeller at both of its ends, said propellers being op positely rotatable but arranged and adapted to propel hthe machine in one direction, an

aeroplane mounted transversely of said elongated body member, a balancing frame depending from said body member beneath said aeroplane, said aeroplane and said balancing frame being arranged and adapted to be tilted with respectto each other, and a weight movably mounted on said balancing fra-me and adjustable lengthwise thereof.

3. A toy flying-machine comprising a tub'ular body member having a propeller journaled at both of its ends, said propellers being rotatable about the axis ot said tubulai body member, a torsional spring-motorelement connecting said propellers whereby the same are rotated in opposite directions, said propellers being arranged and adapted to propel the machine 1n one direction, an aeroplanemounied transversely of said tubular body member and adjustable lengthwise thereof, a balancing frame depending from said tubular body member and adjustable lengthwise thereof, said aeroplane being adapted to be tilted with respect to said balancing frame.
