Description

Patented Nov. 18, 1930 PATENT OFFICE JOSEPH BUIKOWSKI, OF CHICAGO, ILLINOIS i MECHANICAL TOY Application filed January 16, 1930. Serial No. 421,132.

i This invention relates to'fmechanical toys,`

the principal object'thereof being the provision of a toy having a plurality of platforms which could rotate in opposite directions.

" 5` A. further object of the inventionr is the provision of a mechanical toy with a plurality of turning platforms of graduated size and in which the platforms may turn q iny opposite directions.

n With the above general objects in view and others that will appear as the nature of the invention is better understood, the same consistsjin' the novel'combination, construction andv 'arrangement of parts hereinafter more fully7 described, illustrated in -the, accompanying ,drawing and pointed out in the appended claims.

In the drawing forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views, M

Fig. 1 isl a cross-sectional view on vertical plane through the toy; and

Fig. 2 is a top plan view, taken on line 2-2 of F ig. 1.

Referring in detail to the drawing there is shown therein base 10 having in its center rigidly embedded therein the reduced end 11 of stationary post 12. Mounted upon said the upper edge of annular wall 13, said platform 14 having flange 15 at its edge downwardly depending therefrom. Rigid ly afliXed on the underface of said platform and set upon post 12 is a bevel gear 16 having anintegrally formed and downwardly depending collar 17 restingupon bearing 18 which is rigidly afiXed to post 12.

Passing through annular wall 13 is shaft 19 Aterminating at its outer end in crank handle 20, and having at the opposite end a small bevel gear 21 meshing with larger gear 16. Standard 23 positioned near gear 21 forms a bearing for shaft 19'.

base 10 near the edgethereof is an annular Wall 13 enclosing the mechanism positioned'` 14 which is substantially on the plane vwith A number of U-shaped plates 23 aflixed aty their horizontal portions by means of screws 24 to Vbase 10 are provided to receive at the upper ends rollers 25 which contact with the underface of platform 14 for supporting said platform and maintaining the same in its D;

uniform rotary movement.

Positioned above platform 14 are four rods 26 which are arranged in cross-wise formation and by their inner ends rigidly affixed to post 12. Attheir outer ends said rods 2611@ carry freely rotatablelrollers 27, made preferably of rubber or other'suitable frictional material, said rollers contacting with the upper face of platform 414. i

Positionedabove said platform 14 is ani-see other platform 28 of a smaller diameter resting upon said rollers 27. Said yplatform`28 is provided at its edge with downwardly dependingl flangeV 29.

Anotherset of four rods 30 rigidly aliixedi@ by their'inner ends to post 12 is positioned above'said platform 28, said rods carrying a-t their outer ends similar freely rotatable rollers 31 which Contact with the upper face of platform28.k Resting upon said rollersv' 31 is a third platform 32 which is of a smaller diameter than'thezlower platform 28. Said last mentioned platform 32 rhas a similar downwardly depending flange 33 at its edge.

"Positioned above said plat`formf`32 is an-"`- 80 other'set of four rods 34 arranged incrosswise formation and byl their inner ends rigidly afliXed to post 12, which rods carry at their -on Fig.A 1. c Thus, each platform, with relation tothe nextplatform of` a smaller diameter, has an annular free space adjacent its edge upon which-ha number ofv figures 40,169

, means of a number of standards 48, which by representing marching soldiers, horses, ordinances, and the like, are arranged in round formation.

Post 12, adjacent its upper end has a ring 41 rigidly aiiixed thereto by pin 42, constituttheir lower ends 10, as at 49.

Said annular wall 13 at its lower edge is provided with a horizontal fiange 50 which rests upon base 10 and by means of which are rigidly ariixed to base said wall 13 is rigidly aiiiXedt-o said base 10' through the medium of screws 51.

Referring to the operation of the invention, it is observed that each of

rollers

27, 31 and 35 isin frictional contact with platforms which are below and above each respeetive set of said rollers.

Therefore, assuming that crank 20 is turned into a direction to cause platform 14 to turn,

`through the medium. of gears 21 and 16, to

the direction indicated by an arrow on Fig. 2, rollers 27 will rotate in the reverse direction, and the direction of rotation of said rollers 27 will be imparted to platform 28, which will turn in the reverse direction from that of platform 14, since, as already stated, said rollers 27 are in frictional contact with the upper face of platform 14 and with the underface of platform 28. A similar operation .will take place with platform 32 to which the reverse direction of rotation from that of platform 28 will be imparted through` y the medium of rollers 31 which are in frictional contact with the upper face of platform 28 and with the underface of platform 3 2. Thus, said platform 32 will turn to the direction opposite from that of platform 28, but to the same direction with platform 14. Platform 36 will then turn to the direction `opposite from that of platform 82 but the sameras of platform 28, due to the reverse transmission ofmovement through the inef` dium of rollers 35 which remain in frictional contact withthe upper face of platform 32 and the under face of said platform u36. Therefore, said 4fourplatforms in said assumed case will rotate to the directionsl indicated by arrowson Fig. 2. Observation block 38 will remain stationary as already stated. It is to be understood that through the center of each of said platforms passes post 12 around which said platforms rotate.

`From the hereinabove descrip-tion it will be seen that whensaid fourplatforms rotate s in alternate directions, figures 40 arranged upon said platforms will present a striking appearance and a mass of movement since said figures rotate with their respective platforms. Due to the connection of wires 46 between platform 14 and loops 44 and the aeroplane toys 45 will likewise rotate to the same direction to which platform 14 rotates.

lhile there is described herein a preferred embodiment of the present invention it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

1. A mechanical toy comprising a plurality of platforms ofgraduated diameters, a post passing through said platforms and around which the latter are adapted to rotate, a gear aliixed to'one of said platforms, a crank shaft, a gear positioned upon said crank shaft and meshing with the first named gear, and rollers in frictional Contact with each pair of adjacent platforms.

2. A mechanical toy comprising aplurality of platforms of graduated diameters, a post around which the same are positioned. and adapted to rotate, plurality of sets of rods rigidly affixed to said post, each set of said rods being interposed between each adjacent pair of said platforms, freely rotatable rollers carriedy by each set of said "rods, each set of rollers being in frictional contact with each pair of adjacent platforms, means for supporting said platforms, and means for imparting a rotary movement to one of said platforms.

In testimony whereof I affix my signature.
