ABSTRACT:
A velocity indicator for a swingable, striking device for indicating physically the velocity of the striking part at the time of its maximum speed, especially desirable for golf clubs. The indicator is in the form of a single unitary structure easily clamped on a club shaft or taken off without the use of any tools; said indicator being very light in weight, and leaves an indication of a previous swing to compare with a present swing. The device includes a weight member which is linearly displaced during the club swing and acts against a helical tension spring or a pair of rubber bands. A pair of indicator rings on a guide rod are adapted to be pushed by the weight on an initial swing of the club to indicate club velocity with the ring adjacent the weight then being manually retracted leaving the other ring in its advanced position as a target for a subsequent swing pushing the retracted ring so that its advanced position relative to the other ring may be noted to provide a comparison of club swing velocities.
