Starter gun attachment

Claim 2

Apparatus for timing an event comprising a gun, an electrically operated timer remote from the gun for measuring the elapsed time of an event, a microphone operable to sense the sound of the gun being fired, mounting means detachably mounting said microphone on the gun, and an electrical circuit connecting the microphone and the timer operable to produce a signal for actuating the timer when the microphone senses the firing the gun, said circuit including flexible conductor means extending from said mounting means to said timer.

Claim 3

The apparatus of claim 1, wherein said mounting means comprises a magnet.

Claim 4

The apparatus of claim 1, wherein said mounting means comprises a housing having an aperture therein for receiving the muzzle of a gun, and said microphone and said circuit are mounted within said housing.

Claim 5

The apparatus of claim 3, wherein said mounting means further comprises a magnet secured to said housing which is positioned to contact the barrel of a gun when its muzzle is received in said aperture.

Claim 6

An attachment for a starter gun comprising a microphone for detecting the sound of the firing of such a gun, an electrical circuit having input and output terminals, operatively connected at its input terminals to said microphone and operable to produce an electrical signal at its output terminals when such firing is detected by the microphone, mounting means for detachably mounting said microphone and circuit on such a gun, elongated, flexible conductor means connected adjacent one of its ends to the output terminals of said circuit, and connecting means for operatively and detachaBly connecting the opposite end of said conductor means to an electrically operated timing device remote from the gun.

Claim 7

An attachment for a starter gun comprising a microphone for detecting the sound of the firing of such a gun, an electrical circuit having input and output terminals, operatively connected at its input terminals to said microphone and operable to produce an electrical signal at its output terminals when such firing is detected by the microphone, mounting means for detachably mounting said microphone and circuit on such a gun, elongated, flexible conductor means connected adjacent one of its ends to the output terminals of said circuit, and connecting means for operatively and detachaBly connecting the opposite end of said conductor means to an electrically operated timing device remote from the gun.

Claim 8

The attachment of claim 5, wherein said mounting means comprises a magnet.

Claim 9

The attachment of claim 6, wherein said mounting means comprises a housing having an aperture therein adapted to receive the muzzle of such a gun, said magnet is secured to said housing and is positioned to contact the barrel of a gun when its muzzle is inserted in the aperture, and said microphone and circuit are mounted in said housing.

Claim 10

An attachment for a starter gun comprising a housing having an aperture therein adapted to receive the muzzle of a gun, means in said aperture for detachably securing said housing to such a gun when its muzzle is inserted in the aperture, a microphone mounted in said housing, for detecting the sound of the firing of such a gun, an electrical circuit mounted in said housing having input and output terminals, operatively connected at its input terminals to said microphone and operable to produce an electric signal at its output terminals when such firing is detected by said microphone, elongated, flexible conductor means connected adjacent one of its ends to the output terminals of said circuit, and connecting means for operatively and detachably connecting the opposite end of the conductor means to an electrically operated timing device remote from said housing.

Claim 11

An attachment for a starter gun comprising a housing having an aperture therein adapted to receive the muzzle of a gun, means in said aperture for detachably securing said housing to such a gun when its muzzle is inserted in the aperture, a microphone mounted in said housing, for detecting the sound of the firing of such a gun, an electrical circuit mounted in said housing having input and output terminals, operatively connected at its input terminals to said microphone and operable to produce an electric signal at its output terminals when such firing is detected by said microphone, elongated, flexible conductor means connected adjacent one of its ends to the output terminals of said circuit, and connecting means for operatively and detachably connecting the opposite end of the conductor means to an electrically operated timing device remote from said housing.
