' AEROPLANE TOY.

Specification of Letters Patent.

Application filed September 22, 1921. Serial No. 502,312.

To aZZ whom it may concern:

Be it known that I, MICHAEL DYKAs, a citizen of Poland, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Aeroplane Toys, of which the following is a specification.

This invention relates to certain new and useful improvements in aeroplane toys and has particular reference to a toy constructed in simulation of an aeroplane or flying machine and containing a spring motor for operating horizontal and perpendicular propeller blades.

The primary object of the invention resides in the provision of an aeroplane toy embodying a spring motor for operating perpendicular and horizontally disposed ,propeller blades with a cord operated catch dev1ce for the spring motor to control operation thereof and a holding cord for the toy while suspended in the air.

lVith the above general objects in view and others that will appear as the nature of the invention is better understood, the invention consists in the novel form, combination and arrangement of parts hereinafter more fully described in connection with the accompanying drawings and in which like characters of reference indicate corresponding parts throughout the several views.

In the drawings,

Figure l is a top plan view of an aeroplane toy constructed in accordance with the present invention, showing the catch cord for the spring motor and the holding cord for the toy, with the horizontally disposed propellers for raising the toy journaled rearwardly of the side wings and partially overlying the same,

Figure 2 is a horizontal sectional view taken online IIII of Figure 5 showing the spring motor and gearing for operating the propeller blades,

Figures 3 and 4 show diagrammatic plan views of the catch device for controlling the spring motor, Figure 3 showing the catch device in operation, and Figure 4 showing the same disengaged from the spring motor,

Figure 5 is a detail sectional view taken on line VV of Figure 1, 1

Figure 6 is a top plan view of a modified form of the toy showing the horizontally disposed propellers positioned abovethe side wings, and

Figure 7 is another modified form of the toy showing a single horizontally disposed propeller centrally positioned above the aeroplane body or fuselage.

Referring more in detail to the accompanying drawings and in particular to Figures 1 to 5, there is illustrated an aeroplane toy embodying a central body or fuselage 1 carrying upper and lower planes 2 and 3 and having guiding vanes 4 at the rear end of the fuselage.

The propelling means for the toy includes a perpendicular shaft 5 .journaled at its upper end in the upper wall. of the fuselage 1 and having a key portion 6 upon the u per projecting end thereof, the lower end 0 the shaft 5 being fixed in a bearing 7 journaled in the lower wall of the fuselage and provided upon the lower projecting end thereof with a horizontally disposed gear 8. A bevel gear 9 is fixed to the shaft 5 within the fuselage while a coil band spring 10 is secured at its inner end as at 11 to said shaft while the outer end thereof is secured as at 12 to a post 13 depending from the upper wall of the fuselage as clearly shown in Figures 2 and 5.

A shaft 14 journaled horizontally in the fuselage 1 carries a bevel pinion 15'upon the inner end for engagement with the bevel gear 9 upon the shaft 5,-the perpendicular propeller 16 being secured to the forward end of the shaft 14 outwardly of the fuselage 1.

A horizontally disposed propeller is positioned at each side of the fuselage 1, each propellerl? journaled rearwardly and upwardly of the side wings 2 and 3 being fixed to a shaft 18 journaled in rear extensions 19 of the planes 2 and 3 and carrying abevel gear 20 adjacent the lower end thereof. A horizontal shaft 21 journaled at its outer end in a bracket 22 supported on the lower wing 3 and journaled at its inner end in the adjacent side wall of the fuselage 1 carries a bevel gear 23 meshing with the bevel gear 20 upon the shaft 18 while a bevel pinion 24 secured to the inner end of the shaft 21 is in mesh with the bevel gear 9.

A catch device is associated with the spring motor, the same being shown more clearly in Figures 3 to 5 and embod ing spaced hangers 25 and 26 depending rom the fuselage 1 and through which hangers a catch rod 27 is slidabl mounted, a coil.

spring 28 surrounding t e catch rod between the stop washer 29 and the hanger 26 Patented Jan. 17, 1922.

normally to force the catch rod in a direction toward the gear 8 as shown in Figure 3. When the catch rod 27 is retracted against the tension of the spring by the catch cord 30, the lug 31 upon the catch rod engages the hanger 26 to hold the-catch rod retracted against the tension of the spring as shown in Figure 4.

' In the operation of the device, a key 32 as shown in Figure 1 is employed for rotating the shaft 5 'to place the spring 10 under tension, and with the catch rod .27 retracted to the position shown in Figure 4, the perpendicular propeller 16 is rotated for forwardly propelling the toy while the horizontally disposed propellers 17 are similarly rotated for elevating the toy, a holding cord 33 attached to the bottom of the fuselage as shown in Figures 1, 3, and 4 being emplo ed for holding the toy against escape. ith the spring 10 operating the propellers, the toy may be suspended in the air while the spring is under tension, but should it be desired to retract the toy, the catch cord 30 is operated to disengage the lug 31 from the hanger 26 and permit the catch rod'27 to engage the teeth of the gear 8 as shown in Figure 2 arresting movement of the propeller blades while the complete toy is then controlled by the holding cord 33.

It will be noted that the longitudinal axis of the catch rod 27 is at an angle to the longitudinal axis of the fuselage 1, so that by pulling the cord 30 the catch rod 27 is shifted slightly laterally through the enlarged opening in the hanger 26 to insure disengagement of the catch rod lug 31 from the hanger. i

y A modified form of the toy is shown in Figure 6 wherein the horizontally disposed propeller blades 17 are dis osed directly above the upper wings 2, whi e in Fi ure 7 another modified form is illustrated "w erein a single horizontally disposed propeller blade 17" is journaled above the fuselage body.

From the above detailed description of the device, it is believed that the construction.a nd operation thereof will at once be apparent and while there are herein shown and described the preferred embodiments of the invention, it is to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed as new is:

1. An aeroplane toy of the type described comprising a central body, lateral win s carried thereby, a shaft journaled in sald body, a bevel gear fixed to said shaft within the body and a gear wheel fixed to said shaft beneath the body, horizontal shafts journaled on said body and wings, bevel pinions carried by the inner ends of the horizontal shafts in mesh with said bevel gear,.a band spring associated with said perpendicular shaft and bevel gear, a perpendicular shaft journaled at opposite sides of the body, a horizontal pro eller journ'aled on the upper end of each side shaft, gear connections between the side shafts and the horizontal shafts and means associated with the gear carried by the, lower end of the first named shaft for controlling movement thereof.

2. An aeroplane toy of the type described comprising a central body, lateral wings carried thereby, a shaft journaled in said body, a bevel gear fixed to said shaft within the body and a gear wheel fixed to said shaft beneath the body, horizontal shafts journaled on said body and wings, bevel pinions carried'by the inner ends of the horizontal shafts in mesh with said bevel gear, a band spring associated with said perpendicular shaft and bevel gear, a perpendicular shaft journaled atopposite sides of the body, a horizontal propeller journaled on the upper end of each side shaft, gear connections between the side shafts and the horizontal shafts, and a tensioned catch rod associated with the gears secured to the lower end of the first named shaft for controlling movement thereof.

In testimony whereof I aflix my signature.

MICHAEL DYKAS.
