Abstract: A golf ball is shown with an outer surface that is substantially covered with a plurality of spaced dimples that give the ball a suitable long and predictable flight pattern for wood or iron shots due to imparting an increased lift to the ball when the ball is given a backspin. Several modifications of the invention are shown. One or more elongated grooves are formed on the outer surface of the ball for interlocking with grooves that are formed in the face of a golf club so as to increase the grip as well as achieve more "hang time" for a given amount of backspin of the ball. Another modification has a cluster of grooves that is spaced about 90.degree. from the manufacturer's brand name indicia that is marked on the ball. The preferred modification has a continuous band of grooves that encircles the ball and increases the amount of backspin the ball will have leaving the tee which will improve the trajectory or "hang time" of the driven ball.

Abstract: A bowling ball according to one embodiment of the present invention has a hollow member, or a member of less specific gravity than the mass of the bowling ball, disposed therein with its centroid displaced from the geometric center of the ball. The lighter weight member in the ball permits the use of a dense polymerizable composition for the basic mass of the ball. The ball is molded without the usual shell so that it has a resilient striking surface for maximum impact and pin carry. In another embodiment, a member of a higher specific gravity than that of the polymerizable mass is added generally on the same axis as the lighter weight member to increase the eccentricity of the ball and give it even more driving power upon impact with the pins. The member of higher specific gravity may be provided with pin members extending therefrom to the surface of the ball.

Abstract: A golf ball has alternating rough and smooth bands formed in its outer surface and the rough bands are aligned parallel to the ground when the ball is teed up. The rough bands are formed to completely trip the boundary layer of air flow around the ball in order to generate forces which counteract the forces generated by the smooth bands when the golf ball rotates about certain axes of rotation so as to control the path of the golf ball during its flight. The rough bands are formed in a plurality of spaced depressions in the outer surface of the golf ball.

Abstract: Balls comprised of (1) a generally spherically shaped center portion or core prepared from a piece(s) of material, such as a rag or sheet rubber, (2) cohesive tape at least partially covering this center portion, (3) yarn covering the cohesive tape-covered center portion, (4) additional tape (preferably cohesive) substantially completely covering this yarn layer, and (5) a synthetic cloth cover (preferably a double knit polyester). The cover is preferably formed of two figure eight-shaped cloth pieces which have short lines imprinted thereon extending inwardly from the perimeter of each cloth piece such that when the two cloth pieces are joined, corresponding short lines on each cloth piece are aligned such that they either intersect or would intersect if extended thereby simulating the stitching utilized in the construction of conventional baseballs and the like.

Abstract: A golf ball is shown with an outer surface that is substantially covered with a plurality of spaced dimples that give the ball a suitable long and predictable flight pattern for wood or iron shots due to imparting an increased lift to the ball when the ball has a backspin. An undimpled patch is formed on the outer surface for use as a smooth putter-contacting surface. The size of the undimpled patch is chosen to achieve the desired putting accuracy objective without detracting from the increased "hang" time of the flight of the ball. The center of the undimpled patch is substantially spaced between about 90.degree. and 100.degree. from the center of the imprint of the brand name of the ball manufacturer, so the ball may be positioned for putting with the brand name indicia located at the top of the ball, and the location of the undimpled patch being easily discernible from above by the golfer as he stands over the ball and prepares to putt.

Abstract: This invention relates to a golf ball adapted to improve a golfer's score in that the dimples, or cavities, which are aligned on the great circle of the golf ball are provided with diffraction discs whereby the golfer is instantly warned of movement of his eyes and head when looking at the ball while addressing same and executing a golf club swing.In the game of golf, it is most important for the golfer to rivet his eyes to the ball prior to and during the swing of the golf club. Even the slightest movement of this riveted or fixed gaze upon the ball during the swinging of the club can give unwanted and even disasterous results.It is an objective of this invention to provide a new and novel golf ball capable of improving a golfer's game.It is another objective to provide a novel golf ball article of manufacture having diffraction means thereon which indicates, by color change, even the slightest movement of the eyes and head fixed to said ball.

Abstract: An example of the shock resistant transparent polymer sphere is a billiard or pool ball. The molding apparatus includes lower and upper mold halves defining juxtaposed concave hemispherical surfaces to define a spherical mold cavity with a top fill opening on the upper mold half. Interlocking of the mold halves together is accomplished by tongue and window structures circumferentially spaced about the meeting points of the two halves at 120.degree.. A holder in the form of an annular ring is provided for supporting a central disc provided with a symbol on each of its opposite faces. The design is such that the ring when positioned in the spherical cavity defined by the mold halves supports the disc with its center coincident with the center of the spherical cavity. The molded sphere is made by a single pouring operation of resin through the fill opening, the disc and ring being encapsulated within the sphere.

Abstract: In moulding a ball consisting of a cover on a hard spherical core, e.g. a base ball, or a golf ball, one of the problems is maintaining accurate location of the core in the ball. According to the invention the core is surrounded by a moulded shell having co-spherical projections which support the ball in a spherical mould in which the cover is moulded on. The shell may be of two half shells clipped together.

Abstract: An improved two piece aerodynamic throwing disc, commonly known as a flying saucer or Frisbee, having a central wall portion or insert positioned within an opening through and perimetrically secured to an outer annular rim portion. This two piece construction facilitates embossing and/or imprinting of the disc with a design, lettering or the like and provides the disc with improved gyroscopic stability and overall flight characteristics.

Abstract: A puck for playing an ice hockey-like game, on untraditional surfaces, is provided with a generally cylindrical body of foam rubber or the like. Two smaller-diameter disks or end plates of glide material are secured coaxially therewith on respective opposite ends of the body. The disks and main body are attached to each other by adhesive bonding; maybe a provision is made within the main body and between the end disks to receive weights. An aperture is provided for installing selected amount of material internally of the body weighting after the disks and main body have been secured together.

Abstract: A golf ball has a surface pattern of dimples arranged to provide at least 12 symmetrically disposed bald patches, a bald patch being defined in terms of its ability to accommodate a spherical rectangle of specified minimum width and area relative to the dimple size.

Abstract: A transparent game ball particularly useful as a billiard or pool ball is disclosed, along with manufacturing processes and apparatus for producing the ball. The ball includes a weighted opaque object centered within the transparent spherical outer covering of the ball for providing the required weight for the ball as well as a desirable appearance. The transparent portion of the ball is produced bubble free of polyester resin through the use of a special, two-piece mold for forming the entire ball at one time. Into this two-piece mold a centering spider or disk of the same rigid polyester resin is inserted. The spider or disk may be either transparent or opaque, and is used to precisely center the opaque weighted object at the ball's geometric center.

Abstract: A novelty device in the form of a color-changing amusement ball comprising a spherical body member, a transparent spherical cover concentrically surrounding the body member and spaced therefrom to define a spherical cavity, and a layer of liquid crystalline material disposed within the cavity. The liquid crystalline material is responsive to temperature changes and/or deformational stresses applied thereto so that the material changes color with a change in temperature to which the ball is exposed and/or on deformation of the ball which can be accomplished by impacting the ball against a hard surface.

Abstract: An improved billiard ball is provided comprising a major portion and a minor portion together forming a solid, spherical body. The minor portion is preformed with inclined surfaces which define an interlock adapted to cooperate with associated surfaces of the major portion to form a mechanical bond between the major and minor portions after the major portion is formed about the minor portion. When the minor portion is molded in the shape of a bracelet, a slit may be provided therein to relieve stresses caused by shrinkage during cooling.
