Definitions

  • An object of this invention is to provide an improved presettable actuator assembly which furnishes smooth and positive automatic release and locking of the cam by an arcuate movement.
  • the cam When rods 53 and 51 have been properly positioned by manually tuning through knob 21 to the desired frequency, the cam may be locked in place by pressing the pushbutton 25 down sui'liciently to cause the com to align itself with the rods. This presets the cam and provides bearing pressure whereby actuator member 31 will pivot with respect to elongated member 57 to cause projection 91 to force end E5 of clamping bar '75 away from actuator member 31 and toward member 57, placing locking pressure on cam 65, as previously explained.
