Definitions

  • the coupling 232 is operated to engage and disengage the supply hose 234 and the flexible conduits 260 and 262 from the tool by axial movement of the member 254 against the bias of spring 280 to allow the ball detents 270 to move radially away from the groove 282 in the member 236.
  • the conduits 260 and 262 may be flexed, along the portion shown which is not covered by the sheath 264, to allow axial movement of the member 254.
  • the aforementioned passages in the members 236 and 254 leading to the conduits 260 and 262 comprise signal-transmitting means operable to transmit pressure fluid signals produced within the tool 210 to indicating means such as the pressure fluid visual indicators 284 and 286 which may be mounted remote from the tool.
  • the indicators 284 and 286 may be of the type disclosed in applicant's U.S. Pat. No. 3,492,968.
  • the signals transmitted by the conduits 260 and 262 may be converted to an electrical signal in a manner similar to the embodiment of FIGS. 1 and 1a or used to actuate a recording device such as disclosed in the aforementioned U.S. Pat. No. 3,505,928.
  • the present invention provides coupling means for transmitting a signal from a portable hand-held power tool without impairing the handling characteristics thereof and also providing for quick disconnection of the tool from the power supply and the signal-transmitting means.
  • said first member of said releasable coupling is operable to rotate with respect to said second member when said first and second members are engaged and said electrical conductor means on the periphery of said first member is circumferential whereby said electrical contact means on said second member is in signal-transmitting relationship with said circumferential conductor means in any rotative position of said first member with respect to said second member.
