A device for locating bowling ball gripping apertures with respect to a bowling ball weight block angle inherent to that particular bowling ball and the track of a particular bowler. One embodiment of the device includes a curved base portion adapted to substantially rest on a curved surface of a bowling ball, the perimeter of the base portion including degree indicators and the center of the base portion including a hole, at least four curved angle indicator arms adapted to substantially rest on a curved surface of the bowling ball, the angle indicator arms including length measurement indicators, the angle indicator arms connected with and extending from the curved base portion, and at least two of the angle indicator arms are adapted to rotate about the center of the curved base portion. Methods for both diagnostically measuring the location of the gripping holes on a drilled bowling ball relative to the block angle and pin distance to the positive access point and for laying out the placement of gripping holes on an undrilled bowling ball relative to a desired weight block angle and pin to positive access point distance for a particular bowler's track. A device for both measuring and duplicating the thumb hole angle on drilled and undrilled bowling balls, respectively.

Bowling ball angulator and methods of use

The control-enhancing material of the present invention includes a plurality of recesses, such as suction cups, positioned on the palm portion of the bowling glove. The areas covered by the control-enhancing material include the underside of the index finger, the underside of the thumb, the underside of the little finger, and the underside of the middle and ring fingers. Basically, the control-enhancing material is positioned at all or some of the areas on the glove that contact the bowling ball when the glove is worn on the hand of the user and the user is holding a bowling ball. The control-enhancing material works to grip the surface of the bowling ball by a suction force and a friction force. The additional grip is maintained even though the user moves his or her hand slightly either away from, towards, or laterally with respect to the bowling ball.

An insert shim for use in adjusting the size of a finger hole in a bowling ball, the finger hole being formed by a substantially cylindrical wall, and having a closed bottom end and an open top end, and having a standard insert positioned therein. The shim is a semi-rigid member having first and second axes, the first axis being linear and the second axis being arcuate. When inserted in the finger hole between the cylindrical insert and the cylindrical wall, the shim bending to substantially conform to the cylindrical wall of the finger hole. The shim may also be self-adhering and include adhesive means for releasably securing the shim to the cylindrical wall of the ball finger hole.

Bowling ball glove

A bowling aid adapted to be mounted on either the bowler's index or little finger. The aid is a sheath into which the bowler's finger is inserted. Appropriate padding is provided in the sheath for gripping and protecting the finger. The padding can include a full-finger insert having removable serrated longitudinal sections. On the outer end of the sheath there is provided a plate which extends outwardly from the sheath under the head metacarpal joint of the bowler's index finger and part of the palm of the bowler's hand and is provided with a concave surface with a frictional coating thereon for assisting the bowler in gripping the bowling ball. The concave surface and friction coating extend along the length and width of the sheath. The bowler presses the plate and the length and width of the sheath against the surface of the ball to generate enhanced control during ball release. The sheath can define a gap along its length with a fastening system attached to the sheath to accommodate varying finger sizes.

A train communication and control system is described having the cars of the train connected by a two-wire train line running continuously from car to car. Each car has a transmitting circuit and a receiving circuit connected across the line. Any car may be selected to be a master unit. The selection of one car as a master unit disconnects the power sources of all other cars from the train line, leaving the master unit power source as the sole power source for the line. The master unit or any other car unit communicates with each other car by causing a high voltage ('mark' state or logic one) or a low voltage ('space' state or logic zero) to be on the train line. Each non-master car can receive a communication from a transmitting circuit, or can transmit to another car by applying a low impedance across the train line to change from a 'mark' state to a 'space' state. The power source consists of a voltage regulator with precision constant current limit. Output voltage is maintained substantially constant until a load greater than the rated current limit causes the power source to change to a substantially constant current regulator, whereby its regulated voltage falls rapidly to the 'space' state voltage.
