Abstract
Abstract The present invention is concerned with a device for aiding the teaching and training techniques for hitting a baseball accommodating different initial head position and batting style, comprising: a helmet fitted with a mercury switch connected to a motor; a nulling circuit which sets the positional angle of the mercury switch, a tone generator control which activates a tone generator and notifies the batter; two magnetic switches located on each side of the helmet; and, a magnet located on the batter's shirt and a power supply.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
175 words
A device for training a baseball batter in assuming a correct head motion during swinging of a bat, the device comprising: a helmet fitted with a mercury switch attached to a motor in a manner whereby said motor is capable of adjusting position angles of said mercury switch with respect to said motor; a nulling circuit which sets the positioning angles of the mercury switch by causing the motor to move said switch in a first home direction until the mercury switch opens and until a home switch is activated, said activated home switch causing the motor to reverse its direction until the mercury switch closes; a tone generator control which switches on a tone generator when the mercury switch opens and switches off the tone generator when the mercury switch closes; magnetic switches located on the sides of the helmet and connected to the tone generator control, the magnetic switches for detecting tilting of the helmet from side to side; and an electrical power supply with sufficient electrical energy to activate the nulling circuit.
Claim 2
Independent Claim
175 words
A device for training a baseball batter in assuming a correct head motion during swinging of a bat, the device comprising: a helmet fitted with a mercury switch attached to a motor in a manner whereby said motor is capable of adjusting position angles of said mercury switch with respect to said motor; a nulling circuit which sets the positioning angles of the mercury switch by causing the motor to move said switch in a first home direction until the mercury switch opens and until a home switch is activated, said activated home switch causing the motor to reverse its direction until the mercury switch closes; a tone generator control which switches on a tone generator when the mercury switch opens and switches off the tone generator when the mercury switch closes; magnetic switches located on the sides of the helmet and connected to the tone generator control, the magnetic switches for detecting tilting of the helmet from side to side; and an electrical power supply with sufficient electrical energy to activate the nulling circuit.
Claim 3
Dependent Claim
28 words
A device according to claim 1 further comprising an overrange switch which removes power from the nulling circuit when the circuit is unable to find a null point.
Claim 4
Dependent Claim
34 words
A device according to claim 1 further comprising a motor direction control circuit which controls the direction of the motor, monitors the direction of the mercury switch and the status of the home switch.
Claim 5
Dependent Claim
35 words
A device according to claim 1 wherein the motor is mounted in the helmet and oriented such that the mercury switch tilts in frontward and backward direction to an angle of up to 45 degrees.
Claim 6
Dependent Claim
24 words
A device according to claim 1, further including magnets located on a shirt of the batter which are adapted to activate the magnetic switches.
