ALICE FRANCES CORNISH, 0F BIRKENHEAD, ENGLAND.

TOY AIRcRAr'r.

Application. filed J'uly 12,

T 0 all whom it may concern Be it known thatI, ALICE FRANCES Con- NISH, subject of the King of Great Britain, residing inBirkenhead, in the county of Chester and Kingdom of England, have invented certain new and useful Improvements in orRelating to Toy Aircraft, of which the'following is a specification.

The improved toy of the present invention isfin the form of an aircraft of the type in which. the propeller is driven by clockwork motor arranged within the fuselage.

The body of the 'toy' is formed of stamped tin or metal sheeting, the edges of the blanks being connected together with tab and slot connections as is usual or again the'body a may be of stiff paper, cardboard, ply-wood or any other desired material.

The spring-driven motor is mounted upon an .axis parallel with and preferably coincidentwith' the longitudinal axis of the aircraft and is wound up by a shaft extending through to the tail'of the toy aircraft, this shaft being provided with a suitable "number of bearings-alongthe length of the fuselagepreferably on lateral partitions. Similarly the propeller shaft is driven from the spring motor preferably through reduction gearings, the said shaft extending to the front of the machine and being mounted in bearings in further transverse partitions. These transverse partitions may be detachable if desired foraccess to the motor or other parts of the aircraft for renewal of the spring or the like.

Alternately the propeller may be mounted upon a hollow shaft having pinions upon it connected by reduction gearing with a coax ia-l spindle adapted to receive the winding key. a

The present invention is more particularly described with reference to the accompanying drawings in which Figure 1 is an outside elevation of one form of construction.

Fig. 2 isa corresponding view partly in a section of a modified form'of construction.

The toy aircraft consists of a fuselage 1, made up for instance of a single sheet of metal stamping bent round to a suitable contour and secured for instance by soldering, or again by tab and slot fastenings or any other desired usual means of toy construction. The body may conveniently be Specification of Letters Patent.

Patented Jan.'18, 1921. 1920. Serial No. 395,749.

The spring motor 2, is carried in a casing 6, arranged as a separate unit from the body, which latter is slotted as shown at 7, so that I a large spring can be used not necessarily confined to. the internal dimensions of the toy and thus an increased driving force may be obtained;

It will further be seen that this arrangement will have the advantage. that the stream line surface of the aircraft is retained when the spring is wound up.

The spring of the clock work motor 2 may be wound up by means of a shaft 8,extending to the rear and adapted to receive the winding key 9. The clock-Work motor 2, drives, through step up earing 1 0, the shaft 11 of the propeller 4, ti iis shaft being. supported in bearings in two or more lateral partitions 12.

These transverse lateral partitions 12, may if desired, be detachable for access to the motor or other parts of the aircraft when for instance, it may be desired to renew the spring without dismantling the whole toy.

The elements of the step up gearing 10 are mounted on stub shafts so that these spindle 13, adapted to project from a sleeve 14, by the operation of a bayonet catch bolt 15. This arrangement 13, 14, 15, forms an imitation quick firing gun as attached to aircraft. The tail may be formed of tail planes 5 and a tail-fin 16, which may be detachable and a movable rudder '17, the rudder tail of which may be connected to a cord 18, passing Withadouble turn over a rotatable head 19, so that before launching the model, the rudder may be set to any angle desired.

In the modified construction shown in Fig. 2, the spring motor is adapted to be wound up by means of a key20 on a spindle 21, running coaxial with the sleeve 22 on which the propeller 23 is secured. This key may be permanently attached to the spindle if desired. The spindle 21 may of course be extended through to the tail for the reception of the winding key if desired.

The motor, propeller and like parts may be arranged in a housing 24 having a flange 25, by which it may be detachably secured to the front of the body 26 of the toy aircraft,

so that the whole spring motor may be readily removed for instance for inspection or renewal of the parts.

It is obvious that the holes may be arranged in the outside of the body to allow of lubrication of the motor without detachment thereof.

The body of the aircraft may also if desired be built upon a light skeleton of it and connected to another wheelof said said fuselage, a shaft gearing said propeller and driven by one wheel of said spring motor, a separate winding shaft parallel with said propeller shaft and connected to another wheel of said spring motor and extending through the propeller and a winding key on said shaft in front of said propeller.

3. A toy aircraft comprising in combination a fuselage having slotted sides, a propeller, a spring motor driving said propeller and extending through said slotted sides when unwound, and an imitation machine gun parallel with the propeller shaft and sliding axially to said shaft to lock said propeller.

In witness whereof, I have hereunto signed my name this Qth day of June. 1920,

in the presence of two subscribing witnesses.

ALICE FRANCES GORNISH.
