Abstract
Abstract An apparatus for practicing timing includes a pointer to be rotated at a constant tempo in one direction and to be watched by the exerciser and an indicating member to be registered with the pointer at a predetermined position to be thereafter rotated in registry with the pointer. Upon reaching a predetermined position the indicating member is moved in a direction opposite to the direction of movement of the pointer at a higher speed than the pointer and returns to the previously registered position. The exerciser prepares for the timing practice by the movement of the pointer and swings his club in unison with the movement of the indicating member for timing practice. To assure more effective timing practice, auditory practice means is also disclosed in combination with visual practice means. The apparatus further includes means for providing profile of an actual swing form and means for minute adjustment of the swing tempo. Thus, swing form can be corrected along with practicing timing for swinging the golf club.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
121 words
An apparatus for practicing timing for a sport comprising a pointer to be driven at a constant tempo supported on a shaft at the front of a main body provided with a support and an indicating member supported coaxially with the pointer, the indicating member being rotatable together with the pointer approximately a half turn at the same tempo when the pointer comes into registry with the indicating member in the course of rotation, the indicating member being movable backward at a higher speed than in the forward movement from the position where the half turn of rotation is completed to the position where the pointer came into registry with the indicating member, whereby the rhythm of the sport is embodied.
Claim 2
Independent Claim
121 words
An apparatus for practicing timing for a sport comprising a pointer to be driven at a constant tempo supported on a shaft at the front of a main body provided with a support and an indicating member supported coaxially with the pointer, the indicating member being rotatable together with the pointer approximately a half turn at the same tempo when the pointer comes into registry with the indicating member in the course of rotation, the indicating member being movable backward at a higher speed than in the forward movement from the position where the half turn of rotation is completed to the position where the pointer came into registry with the indicating member, whereby the rhythm of the sport is embodied.

33 words
The apparatus for practicing timing for a sport as set forth in claim 1 wherein the indicating member comprises a spring member so as to embody the rhythm of the sport more practically.
Claim 6
Dependent Claim
33 words
The apparatus for practising timing for a sport as set forth in claim 1 wherein a member for adjusting the rotation of the pointer at a constant tempo is included in its circuit.
Claim 7
Independent Claim
203 words
An apparatus for practicing timing of a swinging motion comprising: a. a support structure; b. a first shaft mounted on and projecting from said structure; c. a pointer supported on the projecting end of said first shaft and adapted to rotate relative to said structure about the axis of said shaft in a given direction at a constant speed; d. an indicating member supported coaxially with said pointer adapted to corotate with and at the same speed as said pointer from an initial position to a terminal position when said pointer comes into register therewith at said initial position and, upon reaching said terminal position, to rotate in the opposite direction at a greater speed returning to said initial position; e. first means for rotating said pointer in said given direction at said constant speed; f. second means for corotating said indicating member from said initial to terminal positions with and at the same speed at said pointer when the latter comes into registery with the former at said position and for rotating said indicating member at a greater speed in the opposite direction to return the same to said iniTial position; and g. motive means for actuating said first and second means.
Claim 8
Independent Claim
203 words
An apparatus for practicing timing of a swinging motion comprising: a. a support structure; b. a first shaft mounted on and projecting from said structure; c. a pointer supported on the projecting end of said first shaft and adapted to rotate relative to said structure about the axis of said shaft in a given direction at a constant speed; d. an indicating member supported coaxially with said pointer adapted to corotate with and at the same speed as said pointer from an initial position to a terminal position when said pointer comes into register therewith at said initial position and, upon reaching said terminal position, to rotate in the opposite direction at a greater speed returning to said initial position; e. first means for rotating said pointer in said given direction at said constant speed; f. second means for corotating said indicating member from said initial to terminal positions with and at the same speed at said pointer when the latter comes into registery with the former at said position and for rotating said indicating member at a greater speed in the opposite direction to return the same to said iniTial position; and g. motive means for actuating said first and second means.
Claim 9
Dependent Claim
19 words
The apparatus of claim 6 wherein said motive means comprises a main spur gear driven axially by a motor.
Claim 10
Dependent Claim
