Abstract: An apparatus for monitoring the delivery of material from a spool or the like to a machine which is to perform some work upon the material and draws the material from the spool. The apparatus includes a shaft for accommodating and fixedly securing the spool thereon, apparatus for positioning the shaft at a predetermined location wherein the positioning apparatus also permits the free rotation of the shaft about the longitudinal axis thereof, apparatus for providing a pulsed electrical signal upon rotation of the shaft, the pulsed electrical signal device having an element thereof directly coupled to the shaft for rotation as a result of the rotation of the shaft, and apparatus for indicating the output of the pulsed electrical signal device wherein the apparatus which does work on the material can be shut off if the material being fed from the spool becomes tangled, snarled, or otherwise jammed or is consumed.

Abstract: A cutting apparatus for cutting strip material including a housing with a longitudinal and transverse axis and having an enclosed portion and an open work receiving portion, rollers for feeding strip material along the transverse axis of the open portion, and scissor-like means transversely disposed within the open work receiving portion for shearing the strip material.

Abstract: A bracket device has an extended plate-like body member with an upstanding cylindrical extension formed at one end and externally threaded for coupling to an engineers instrument, and a clamp means formed at the other end to mount the device to a column.
