Abstract
Abstract A communications headset in which a unidirectional microphone at the end of a support boom is adjustably secured in a position selected by the wearer. The support boom is clamped under adjustable compression in a ball-and-socket arrangement which, at reduced compression, allows the boom to be moved longitudinally, pivoted about its axis, or pivoted about the center of the ball. The wearer turns a knob to compress the ball-and-socket joint to secure the boom in the position desired. A tube transmitting sound from the receiver to an ear plug is adjustably attached to the headset by means of a second ball-and-socket joint. A pivoting clamp attached to a pivoting temple member permits the microphone support assembly to be switched from one side of the head to the other as desired.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A communications headset comprising: a resilient headband adapted to be worn over the head, a substantially rigid microphone boom having a sound pick-up at one end thereof, and adjustable mounting means attached to said headband for securely supporting said sound pick-up in a position selected by the wearer, said adjustable mounting means comprising, in combination, first and second hemispherical members having substantially equal curvatures together forming the ball of a ball-and-socket joint, at least one of said hemispherical members being recessed to form a passageway for slidably receiving said boom, first and second bearing members having opposing surfaces forming the socket of said ball-and-socket joint, and means for applying an adjustable clamping force to said bearing members to place said ball and said boom under variable compression.
Claim 2
Dependent Claim
127 words
A communications headset comprising: a resilient headband adapted to be worn over the head, a substantially rigid microphone boom having a sound pick-up at one end thereof, and adjustable mounting means attached to said headband for securely supporting said sound pick-up in a position selected by the wearer, said adjustable mounting means comprising, in combination, first and second hemispherical members having substantially equal curvatures together forming the ball of a ball-and-socket joint, at least one of said hemispherical members being recessed to form a passageway for slidably receiving said boom, first and second bearing members having opposing surfaces forming the socket of said ball-and-socket joint, and means for applying an adjustable clamping force to said bearing members to place said ball and said boom under variable compression.
Claim 3
Dependent Claim
47 words
A communications headset as set forth in claim 1 wherein said sound pick-up is a unidirectional microphone and wherein said boom has a circular cross-section at least at said ball-and-socket joint to permit the wearer to pivotally position said microphone when said adjustable clamping force is reduced.
Claim 4
Dependent Claim
30 words
A communications headset as set forth in claim 1 wherein said adjustable mounting means are removably secured to said headband by means of a clamp pivotally mounted on said headband.
Claim 5
Dependent Claim
67 words
A microphone-supporting headset comprising, in combination, a resilient, semicircular headband adapted to be worn on the head, a temple member pivotally attached to said headband for rotation about a first axis, a mounting bracket pivotally attached to said temple member for rotation about a second axis spaced from said first axis, and a microphone support removably attached to said temple member by means of said mounting bracket.
Claim 6
Dependent Claim
67 words
A microphone-supporting headset comprising, in combination, a resilient, semicircular headband adapted to be worn on the head, a temple member pivotally attached to said headband for rotation about a first axis, a mounting bracket pivotally attached to said temple member for rotation about a second axis spaced from said first axis, and a microphone support removably attached to said temple member by means of said mounting bracket.
Claim 7
Dependent Claim
44 words
The headset of claim 4 including first detent means for securing said temple member in two stable angular positions with respect to said headband and second detent means for securing said mounting bracket in two stable angular positions with respect to said temple member.
Claim 8
Dependent Claim
18 words
A headset as set forth in claim 4 including an ear tube pivotally mounted on said microphone support.
