Application September 12, 1947, Serial No. 773,623

This invention relates to an improved self propelling figure toy.

More particularly the invention relates to a toy which is constructed so as to simulate a skier, and which moves over a horizontal or slightly inclined surface by successive movements of ground engagin poles operated by a spring operated mechanism housed in the body of the toy skier figure.

One of the objects of the invention is to provide a toy skier figure with a body which is constructed so as to simulate a skier in a normal partly crouched position. Such a skier figure is supported upon skis having a rolling action on the floor or ground and provides movable spring operated arms and poles supported thereby, which arms and poles have a repeated pushing action against the ground or other supporting surface ing a reduction gear train so arranged that its ,friction acts as an escapement for the unwind- "ing of the spring motor. The toy skier is further provided with a crank arm which is connected to pivotally supported arms of the figure by means of a link so arranged that a swinging motion is imparted to the arms and to the propelling ground poles carried thereby.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. l is a perspective view, showing the skier in motion producing position.

Fig. 2 is a partial front elevation of the skier figure, partly broken away, to illustrate the spring motor and the drive for the arm swinging shaft.

Fig. 3 is a partial side elevational view, shown partly in vertical section, illustrating the position of one of the arms and its propelling pole.

Fig. 4 is a detail enlarged sectional view of the 3 Claims. (01. 46- 107) spring motor, showing the crank shaft andconnecting pitman drive for the swinging arms. Fig. 5 is a bottom plan view of one of the skis. Fig. 6 is a detail enlarged sectional view, showing bearing members for the arm swing shaft, of a modified construction, taken on line 6-6 of Fig. 1, looking in the direction of the arrows.

Fig. 7 is an enlarged vertical sectional view taken on the line of Fig. 3. The self propelling toy, according to the pres- .ent invention, includes a body [0 simulating the simulate a skier in the natural position of proelling himself over the ground by pushing hand carried poles against the ground.

The legs II are shown with their upper or hip portions bent at a rearward angle to themselves, thus disposing the figure in a semi-crouching position to simulate the natural position of a skier engaged in propelling himself over the ground by the manual operation of pushing poles. The feet 16 are secured by means of fasteners I! to the skis l8 and I9. These skis are shown to be formed of plastic or sheet metal, which may be aluminum or other metal, and provided with a forward end portion 20, which is curved upwardly. 7 Each ski has two wheels l8 mounted to turn in slots lB on shafts l8.

The body In is of hollow construction to provide a compartment in which a spring motor 2! is housed. This toy spring motor includes the metal frame 22 rotatively supporting a main spring arbor or shaft 23 which turns in bearings of the frame 22, and which shaft 23 carries the spring 24 and the drive gear 25. The drive gear 25 drives the pinion 26 of the shaft 2? which also turns in bearings of the frame22 and is provided with a crank arm 28 on one end thereof. The

shaft 21 carries a transmission gear 29 which engagesthe pinion 30 on the shaft 3| and this shaft 3| carries a gear 32, which drives the pinion 33 .on the shaft 34. All of the shafts turn in bearings of the frame 22. The shaft 34 has a gear 3 which drives the pinion 34 A shaft 35 is also mounted to turn in the bearings of the frame 22, and is provided on its outer ends with

squared portions

36 and 31 On the end portion 36 of the shaft 35, the arm [4 is mounted, the same being connected thereto to swing with the shaft 35 and not upon it. On the opposite end portion 31 of the shaft 35, the arm M is mounted to swing with the shaft and not independently of the shaft.

The shaft 35 is provided with a short lateral arm or lug 40 which is keyed thereto against relative turning, and the upper end of the pitman or link'rod A vpivotally c nne e t 2 to said arm or lug 40. The lower end of the pitman or link rod 4| is pivotally mounted on the crank arm 28.

One outer end of the spring arbor or shaft :23 projects outwardly of the body and is squared to receive a winding key.

The arms l4 and Ill swing against the sides of the body In and are wholly supported on the ends of the shaft 35, to which they are interlocked against relative ,turning. Each of'these arms is equipped with a gloved hand 43, which isconneete dthereto, as by the pivot pin '41. Qn each hand, a" pushing pole 45 is secured' "Thelower' end of each pushing pole is provided with a sheath lfi'of leather or other fric..

tional material. The square portions 38 and 31 'of the shaft 35 are disposed in the same angular relations to each'other and 'to the body I'll, so that the lower end of one of the arms will engage the ground orfloor at the same time with the lower end of the other arm. The lower ends a of both poles engage the ground or floor outvvardl'y of the outer sides of the skis, so as not to interfere with the movement of the wheel equipped'skis over-the ground or floor.

" 'If desired the

square portions

36 and 31 may also be disposed in difierentangular relations to eachother so that the lower end of one arm 'will engage the ground or floor before the lower end ofthe other arm and by means of this arrangement one pole will start its pushing or propelling stroke when the other pole hasreached a point (nearly the limit of" its own pushing stroke. By winding the spring, energy will be stored up and the gear train will be started in motion, thereby driving the' crank shaft and oscillating the rock shaft 35. To insure an easy motion to this rock shaft, metal bearings 41 are proyided in the body I ll therefor. The connection between each arm and the rock shaft may in- .-1Lld a metal sleeve 48, having an integral disc conar 48*, by which it is interlocked or cemented to the u er end of the ar 5 ha the a will'notbe displaced on the end of the rock ha t When the rock shaft 35 is oscillated by the action of the pitman or link rod' 4|,the square portions 36 and 3'! will be swung back and forth, andas they are swung, the" lower ends of the poles 45 will be forced against the ground or floor, and the toy will be propelled forwardly, thus simulating the natural movements of a skier. While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right'is reserved to all changes and modifications coming within'the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secur'e'by United States Letters Patent is:
