Abstract
Abstract A plurality of feelers are pivotally mounted on an elongated support pipe. A contact member is positioned adjacent the feelers, extending between support rods which are positioned on either side of the feelers and which are also secured to the elongated support pipe. The control member and the feelers are part of a low voltage circuit which is completed when the feelers are pushed into the contact member. The low voltage circuit can be used to shut down a press or to monitor the passage of parts. The angle of the support rods with respect to the vertical can be varied to thereby vary the distance between the contact member and the feelers. The elongated support pipe is itself secured to a main support pipe by yokes which can be adjusted to allow one to move the feelers either closer to or farther from the press. A handle is secured to the main support rod to allow one to pivot the contact member into the feelers and then lift them up and out of the way completely. In an alternative embodiment, the feelers are fixed at one end to the elongated support pipe, but have spring sections which allow them to be pivoted. The contact member comprises a bracket having apertures therein through which the feelers extend. Movement of the feelers causes them to engage the contact member through which they extend and thereby shut down the press or monitor parts.
