No. 825,393 4 Claims. (Cl. 27386) My invention relates to a game of skill or the like which may be used by a single person for amusement or competitively by a group of persons.

In my new game I use a set of differently sized and shaped rotational bodies having a circular base face. I have found that all bodies of such set, provided that the diameter of said circular base face does not substantially exceed the greatest diameter of the body and further provided that in all bodies of the set the linear sum of said diameters and of the distance between the planes containing said diameters is substantially identical, per form substantially similar, though in magnitude differ-ing, rotational and pendulating movements when spun on a supporting board about their inclined rotational axis with the plumb line containing the center of gravity passing through said circular base face. With said provisoes adhered to the said rotational bodies may have any desired size and shape; for example they may substantially have the shape of a truncated cone or of a goblet or the like, they may be solid or partially hollow, and they may be made of any material having a substantial specific weight for example from glass, ceramic or plastic material, or metal. When the bodies are spun on a supporting board the successive contact points between the base face and the board will move along a substantially cycloidal trajectory; if the board is horizontal the center line of the trajectory will be more or less curved according to the skill of the operator; if the board is inclined said center line will be flattened and depending on the skill of the operator even straightened so that it will extend substantially perpendicular to the slope of the inc-lined board.

The said and other objects of my invention will be more fully understood from the following specification when read with the accompanying drawing in which several embodiments are illustrated. In the drawing FIG. 1 shows in front view a truncated conical body being one of differently sized and shaped rotational bodies forming a set in accordance with my invention,

FIG. 2 shows in front view a substantially gobletshaped body being one of differently sized and shaped rotational bodies forming a set in accordance with my invention,

FIG. 3 shows the substantially cycloidal trajectory formed by succeeding contact points between the supporting board and the circular base face of the rotational body when the same is spun about its inclined rotational axis,

FIG. 4 shows in front view another rotational body and the manner how it is manually spun about its rotational axis,

FIG. 5 shows in front view a set of rotational bodies interrelated according to my invention,

FIG. 6 shows in front view a set of rotational bodies supported by an inclined board, and

FIG. 7 shows the trajectories of said bodies on said inclined supporting board.

The same reference characters indicate the same or equivalent elements in all figures of the drawing.

The set of rotational bodies according to my invention may be composed of differently sized and shaped conical bodies 11 shown in FIG. 1. The bodies 11 are spun about their rotational axis 16 as indicated by arrow 19. The plumb line 17 passing through the center of gravity 14 of the body should not pass beyond the base :face 12. Succeeding contact points 15 between the supporting board 18 and each of the spun bodies 11 of the set will move along substantially similar cycloidal trajectories 20 having a curved center line 21 as shown in FIG. 3.

FIG. 2 shows a rotational body 11 having substantially the shape of a goblet. The upper part of the body 11 may be substantially cylindrical as shown in full lines or it may be bulged as shown in dotted lines, and in either case either solid or hollow. The diameter of the base face 12 does not exceed the greatest diameter d of the body. As stated above with regard to the embodiment shown in FIG. 1 the plumb line 17 passing through the center of gravity of the body 11, when the same is spun about its inclined rotational axis, should not pass beyond the base face 12 of the body and the bodies of a set will move along substantially similar cycloidal trajectories 20 as shown in FIG. 3.

FIG. 4 shows another shape of a rotational body 11 in a set according to my invention and the figure also indicates how such body is manual-1y spun about its rotational axis 16 in the direction of arrow 19.

FIG. 5 shows six differently sized and shaped rotational bodies 11 forming a set according to my invention. The individual bodies 11 of the set are so interrelated that the sum of the diameter d of the base face 12, of the greatest diameter d of the body and of the distance d between the planes in which said diameters d and :1 are located is substantially identical in all bodies 11 forming the set.

FIG. 6 shows a set of rotational bodies 11 supported by an inclined base plate 22. When the bodies 11 are spun starting at one of the inclined edges of the base plate 22 the center line 21 of the cycloidal trajectory 20 (see FIG. 3) will be flattened or even straightened as shown in FIG. 7 depending on the skill of the operator.

While specific embodiments of my invention have been shown and described in detail to illustrate the application of the principles of my invention, it will be well understood that the same may be otherwise embodied without departing from such principles.

What 1 claim as my invention:

1. A game of skill comprising a set of rotational bodies having a circular base face; in each of said bodies the diameter of said base face not substantially exceeding the greatest diameter of the body; and in all bodies the sum of said diameters and of the distance between the planes containing said diameters being substantially identical; said rotational bodies being differently sized and shaped to perform generally similar rotational and pendulating movements differing in magnitude when spun about their inclined rotational axis with the plumb line containing the center of gravity of the respective body passing through said circular base face.

2. A game of skill comprising a set of rotational bodies; each of said bodies composed of a circular base disk, an upper body and an intermediate connecting stem; in each of said rotational bodies the diameter of said base disk not substantially exceeding the greatest diameter of said upper body, and in all bodies the sum of said diameters and of the distance between the planes containing said diameters being substantially identical; said rotational bodies being differently sized and shaped to perform generally similar rotational and pendulating movements differing in magnitude when spun about their inclined rotational axis with the plumb line containing the center of gravity of the respective body passing through said base disk.

3. A game of skill according to claim 1 and comprising a tiltably mounted desk board supporting said rotational bodies when being spun and causing the rotating and pendulating bodies to move in a direction substantially perpendicular to the slope of the board.

4. A game of skill according to claim 2 and compris- Patented Aug. 14, 1962' 3 ing a tiltably mounted desk board supporting said rotational bodies when being spun and causing the rotating and pendulating bodies to move in a direction substantially perpendicular to the slope of the board.
