orronrLANn, OREGON H HELICOPTER To? Application filed December 28, 1929. Serial No. 417,161.

The present invention relates to toys and more particularly to helicoptical toys.

An object of the present invention is to provide a toy of this character wherein a propeller is projected upwardly from the toy upon rotation of the device.

Another object of this invention is toprovide a toy which may be readily and easily manufactured and which may be so constructed as to withstand extremely hard usage.

A further object of this invention is to provide a device wherein the handle and pivot are formed integrally so that the handle and pivot may be constructed of a section of wire or the like.

The above and various other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein V Figure 1 is a detailed side elevation partly as in section of a device constructed according to the preferred embodiment of this invention; I

Figure 2 is a top plan view of the projectile member; and

Figure 3 is a fragmentary perspective view of the retaining stop means for the operating member.

Referring to the drawing wherein like numerals of reference designate correspond 1 ing parts throughout the several views, the

numerallO designates generally the handle portion of a helicoptical toy constructed according to the preferred embodiment of this invention and which may be constructed of a section of wire which is provided with a substantially elongated looped portion 11 which may be grasped in the hand.- One of the free ends of the loop member 10 may be bent into a second loop member 12 and extended upwardly as at 13 so as to provide ashaft or pivot member, the use of which will be hereinafter described. The opposite end portion of the loop 10 is preferably extended upwardly through the smaller loop 12 and bent in a substantially horizontal plane about the lower end portion of the shaft or pivot mem- I ber 13 asflat 14: so as to provide a base for an operating member or spool 15. a i r V The horizontal loop14: is adapted to have V relative horizontal movement about the shaft 13. The lower end portion. of the spool member 15 is provided with a restricted portion 16 which is adapted to rotatably seat on the upper edge portion of the loop 14, andan annular groove 17 is interposed between the .re-' stricted member 16 and the lower end portion ofthespool 15. The horizontal loop 1a is preferably extended upwardly in a substantiallyvertical plane, and the free end'of the wire is bent'inwardly 'at at 18 so. as to provide a stop which will loosely engage in the groove 17 and not only prevent'thespool 15 from movingupwardly onthe shaft 13 but when the loop 11 has been squeezed'by the hand, the horizontal base sectionld will move laterally so as ,to cause the f'reejend of the stop member 18 to engage the spool so as to prea vent turning thereof on the shaft 13. a

The spool member 15 isprovided an- 5a opening 19 which is adapted to extend substantialy horizontally through the spool and in which a flexible member 20 may be mounted andwound around the spool, the inner end of the flexible member being rovided with a knot or enlarged portion 21 so as'to retain the flexible member on the spool. The spool 15 is provided'with a plurality of upstanding pins 22 on the upper portion thereof preferably positioned diametrically opposed to each other and in spaced relation to the axis of the spool.

A propeller or projectile member 23 is provided with an axial opening 24 for loosely facilitate the winding of the string 20 about i the spool 15, the handle 10 may be squeezed so as to laterally move the stop member 18 so as to hold the spool 15 against movement on the shaft 13. The outer end portion of the flexible member 20, which is provided with an apertured bead or the like 26, may be pulled horizontally or outwardly thereby turning the spool 15 and the speed of the spool will cause the propeller or helicopter 23 to rotate, and when the propeller rotates .at a sufficiently rapid rate it will rise upwardly from the pins :22 and off of the axial shaft member 13 and spin around in the air.

In the construction of the device, the handie member 10 and the axial shaft 13 may be constructed integrally with each other and constructed of a substantially resilient Wire member.

It will, of course, be understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of the invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

What is claimed is A toy of the character described comprising a resilient looped handle member, a shaft outstanding from said handle, a pulley loose- 1y mounted on said shaft, said pulley having a restricted lower end portion, said pulley also having an annular groove intermediate the pulley and said restricted lower end portion, stop means mounted on said handle and engaging said pulley in said grooved portion, a plurality of diametrically spaced pins mounted on the upper end of said pulley, a flexible member engaging said pulley, and a propeller loosely engaging said upstanding pins on said pulley and adapted for rotation thereby.
