TOY FLYING MACHINE.

Application filed June @1923. Serial No. 044,362.

To all whom it may comm:

Be it known that I, HENRY V. DE'MPSTER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Toy Flying Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a toy and particularly to a toy in the form of an aeroplane. Aeroplane toys continue to be exceedingly interesting and entertaining to children, es-

to provide such a toy comprisin an aero-v plane having a hollow fuselage-su stantially rectangular or square in cross section, a removable plane extending transversely thereof, a pin loosely mounted beneath the plane to which one end of a string is .connected, the other end of said'string being secured to the end of an elongated handle.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the dilferent views, and in which .Fig. 1 is a plan view of the device;

Fig. 2 is a Vertical section taken on the line 22 of Fig. 1, as indicated by the ar-. rows; and

Fig. 3 is a View in end elevation of the device as seen from the right of Fig. 1.

Referring to the drawings, a toy is illustrated comprising a device simulating an aeroplane structure having a fuselage memher 1. The member 1 is hollow and preferably made from a single rectangular blank of light sheet material, such as cardboard,

having a tab extending from one end thereof. The said blank is folded to form an open ended box-substantially rectangular or square'in cross section. The corners of said box are slitted and the sides of the box at said slits fold inwardly and are fastened together by glue, or 'other suitable means, thus forming inwardly projecting ribs 2, as shown in Fig. 3. The ends of the member 1' are thus given a tapered' shape and the same conveniently reinforced. The tab at the end of the blank is then folded substantially at right angles to the sides of said box and glued, or otherwise fastened in position to form a closed end 3 for the fuselage. The top side of the member 1 is transversely slitted at spaced points somewhat toward the front-end thereof, to provide oppositely disosed lips 4. The rear end of the'member 1 is open and the sides thereof are transversely slitted to receive a horizontal tail rudder 5 which is glued or otherwise suitably secured to the member land also has secured thereto a vertical tail rudder 6 disposed in a slit in the top side of the member 1 and havingits lower edge bent substantially at a right angle and glued or otherwise secured to the member 5. A small headed'pin or tack 7 is secured axially in the front end 3 of the member 1 and has journaled thereon a helical blade 8 having oppositely extended arms. A wing or plane member 9 of flat sheet material is provided and is removably held in position on the member 1 by having" its sides extending under the lips 4. The member 9 will be bent somewhat along the longitudinal axis so as to dispose the sldes beneath the lips 4 and when said member is in osition. It will preferably be held in slig tly curved form. A pin 10 is loosely mounted beneath the plane 9 and the latter has a small aperture extending centrally therethrough, through which extends a cord or string 11, one end of which is secured to the pin 10. The other end of the string 11 is secured adjacent one end of an elongatedrod 12 forming a handle member. 7

In operation, the rod 12 is held adjacent its free end and the other end swung about the head or in the form of a figure 8 in front of the operator. The aeroplane thus moves through the air in flying position and the pressure of the air against the blade 8 causes the same rapidly to revolve and the aeroplane thus appears to fly through the air. The string 11 is swivelly connected to the plane 9 by the loose pin 10 so that there is no twisting of the string as the toy is operated. The plane 9 can readily be removed by bending the same and withdravi ing it from beneath the lips 4 when the toy is packed, or if it is necessary to examine the connection of the string. The toy is constructed so as to be balanced about the axis from which the string 11 extends so that it will maintain a proper balance or flying position. The string, of course, should be of sufficient length to allow the aeroplane to have considerable scope of travel and with a little practice the aeroplane can be made to do many flying stunts. The propeller continuallv revolves and produces a buzzing sound, thus simulating, in a remarkable degree, an actual flying machine.

From the above description it is seen that ap licant has provided an extremely simple an eflicient toy and one which will greatly interest and amuse children. The device is very easily and quite inexpensively made .and can be marketed at a very reasonable figure. The same has been amply demonstrated in actual practice and found to operate very successfully.

' applicants i It will, of course, be understood that various changes may be made in the form, de-

tails, arrangement and proportions of the freely revoluble helical blade journaled on. said pin, a string passing through said plane in line with the longitudinal axis of saidfuselage and retaining means on said string between said plane and-fuselage, and a comparatively long rod to one end of which said string is attached.

2. A toy device comprising an aeroplane having a hollow fuselage of sheet material, a plane detachably connected to the top of said fuselage, horizontal and vertical tail rudders secured to the rear of the'fuselage,

a freely revoluble blade mounted. at the front'of said fuselage, a string passing through the top of said plane at the transv verse center and substantially at the ion itudinal center thereof, retaining means or said vstrin disposed loosely beneath said plane to w ich one end of the string is secured, and an elongated handle rod to one end of which the other end of said string is secured.

3. A toy device comprising anjaeroplane having a hollow substantially closed fuselage made of sheet material and being substantially square in cross section, the top of said fuselage being oppositely slitted to form spaced oppositely directed lips, a plane of sheet material having its sides disposed under said lips and held in, place thereby, a cord extending centrally through the top of said plane, means secured to said cord beneath said plane for holding the cord in po- -sition, said fuselage being slit at its corners adjacent its front and rear ends and the edges of said slits being inturned and secured together to give the fuselage a tapered I ihape and forming reinforcing means there- 4. A, toy device comprising an aeroplane having an elongated hollow fuselage substantially square in cross section and made from a blank of foldedlight sheet material, said folded blank being slit at its corners adjacent each end of the fuselage and the slit edges folded inwardly substantially at an angle of 45 degrees and secured together to form reinforced tapered ends on the fuselage, the top of said fuselage being provided with oppositely directed slits, a plane having its longitudinal edges i serted in said slits and having a eentra aperture therethrou'gh, a short rod disposed between the top of the fuselage and said plane, and a string attached centrally to said rod and passing out through the aperture in said plane and forming a manipulating member for said toy. i

5. A toy device comprising an aeroplane .having a hollow closed fuselage of sheet material, a plane adjacent the forward end of said fuselage having its frontand rear edges detachably insertedin the top of said fuselage, a, pin secured in and projecting forwardly from the front of said fuselage,

a freely rev'oluble helical blade journaled on said pin, means engaging the underside of the top of said fuselage for securing a string, and astring attached to said means and extending upwardly therefrom substantially centrally of said plane and a comparatively long .rod to one end,of which said string is attached.

In testimony Whereof I affix my signature.
