TOY AIRPLANE Ernst Horn, Nuremberg, Germany Application January 19, 1937, Serial Nb. 121,357 In Germany January 31, 1936 2 Claims. (CI. 46-78) This invention relates to toy-airplanes and rod I0 extends into the interior of the fuselage more particularly to toy-airplanes that are driven I and is guided therein by means of the bent by means of a propeller and a clockwork and suspended from a string or cord. 5 As compared with known toys of the present kind, my present novel toy-airplane consists es sentially therein that at the tail of the fuselage‘ there is provided amovable tail-rudder which at the commencement of the ?ight is obliquely positioned and adjusted by means of said clock work automatically into straight direction, as soon as the toy-airplane which is suspended from a cord or string has been directed into its normal, circular ?ight. , off end or nose of a prolonged rail I2 that forms part of the casing of the clockwork 5. On said rail I2 there is further mounted a slide I3 which (PI is longitudinally displaceable thereon and which is under action of a retracting spring I6, said slide I3 co-operating with a cam-disk or eccen tric I4 mounted on said winding-stem 6, a fric tion clutch I5 being inserted therebetween. Backward rotation of the winding stem 6 which takes place during running of the clockwork will cause said cam-disk or eccentric I4 to rotate therewith, the latter now acting upon said slide I3 to displace the same in longitudinal direc tion, thus to push said actuating rod III for the tail-rudder 8 towards the outside and to adjust By so arranging the toy-airplane the said nor mal circular ?ight will be automatically initiated from the suspended condition of the toy and‘ after the latter has assumed normal circular said rudder into its straight position with respect motion, said tail-rudder is automatically ad to the fuselage I. Adjustment of the rudder 8 justed into straight position by action of said into its oblique position, as indicated in Fig. l, clockwork, thus maintaining the further circular is effected by hand and limited by a lateral stop normal ?ying motion of the toy. ‘ II on the tail of said fuselage. In obliquely ad ~The toy-airplane now may enter from its sus justed position of the rudder 8 the airplane will pended condition into said circular normal mo- ‘ start from its suspended condition into its nor tion in fully equalizedcondition and does not need to be thrown by hand into said motion. In addition, the novel toy-airplane when being started from said suspended condition to, follow mal circular path of motion and after it has assumed this motion the rudder 8 is being moved into its straight position by action of said cam; disk or eccentric I4 which is rotating with the its normal circular path of motion will no more be subject to any rotation or similar motion work 5. round the suspension-cord. Also, any failure of the toy-airplane to start will be positively avoided and the latter caused to gradually move quietly and in fully equalized condition from its sus pended condition ?rst into a single spiral path of motion and thereupon into its normal circular path of motion andv continuously kept therein during operation of the clockwork. ' In the accompanying drawing, which forms 40 part of this speci?cation, I- have shown some examples of construction of my novel toy-air plane, Fig. 1 being a bottom-view of one con struction of my present toy, Fig. 2 a lateral view, partly broken away, taken on Fig. 1, and Fig. 3 45 an enlarged partial detail view showing the clockwork and the controlling mechanism for properly steering the aforesaid tail-rudder. In my novel toy-airplane, the hollow body or fuselage I is provided with a wing 2 detachably secured thereto. Said fuselage I is further - a spring-driven clockwork 5 with a downwardly projecting winding-stem 6. To the rear end of the fuselage I, there is hinged, as shown at ‘I, the‘ tail-rudder 8, and an actuating rod I0 is ,55 pivoted as shown at 9 to said rudder 8. Said winding-stem 6 during the running of the clock Subsequent to the outward motion of . said rod ID by action of the slide I3 and sub sequent to the 'motion of the rudder 8 into straight position, further rotation of said cam disk I 4 will no more act on said rod III, that is" to say, said rudder during normal circular flight of the toy-plane will remain in the same posit-ion with respect to the fuselage. On the other hand, . said rudder is again adjusted into its oblique position by hand after having again wound-up the clockwork. 40 While I have shown and described what is now thought to be a preferred embodiment of my device, yet it is to be understood that it is susceptible of other forms and expressions within the spirit and scope of the invention as herein~ after claimed. I claim: - 1. A suspended toy airplane, comprising sus pension means, a fuselage, wings, a propeller, and a rudder, said rudder being adapted to be po sitioned to direct said airplane into a circular course from a stationary pendant position, a rud der actuating rod having one end operatively connected to said rubber and having the other end positioned within said fuselage, a pdwer 2 2,122,848 plant in said fuselage and operatively connected in said fuselage and operatively connected to said to said propeller to-actuate the'same to move propeller to actuate the same to move said air said airplane in a generally forward direction, plane in a generally forward direction, a rotat means associated with said power plant and op ing cam operatively connected for rotation to erable thereby to engage the inner end of said 7 said power plant, a rail member in said fuselage, rod to move the same to position said rudder to maintain said course after the forward move ment of said airplane has commenced, and said means thereafter being disengaged from said rod ' ll) to permit the maintenance of said rudder in said last named position. 2. A'suspended' toy airplane, comprising sus pension means, a fuselage, wings, a propeller, and a rudder, said rudder being adapted to be posi tioned to direct said airplane into a circular course from a stationary pendant position,‘ a rud der actuating rod having one end operatively connected to said rudder and having the other end positioned within said fuselage, a power plant a slide mounted on said rail member, spring means normally maintaining said slide adjacent one end of said rail. said slide being engageable with said cam for sliding movement against the action of said spring, a portion of said slide dur ing said movement being adapted to engage'the inner end of said rod and move the same there with in a direction to move said rudder from said ?rst named position to a position to maintain said course, said slide being t'hereafter disengaged from said rod-to permit the maintenance of said rudder in said last named position.
