Abstract: A cutting device is provided for opening the container of a standard oil filter and comprises a rigid mounting frame; first and second support disks rotatably mounted to the mounting frame, the first support disk including an outer edge which is roughened so as to frictionally grip the oil filter; a handle for rotating the first support disk; and an adjustable, rotating cutting blade, the cutting blade made adjustable by an advancing mechanism such as a screw. The first and second disks and cutting blade are disposed relative to each other so as to support the oil filter when the adjustable cutting blade is properly positioned. The oil filter is then rotated by the handle such that the cutting blade effectively separates the top and bottom portions of the oil filter.

Abstract: Strip feeding mechanism for a terminal applicator comprises a feed pawl which is mounted on an oscillatory pawl carrier so that oscillation of the pawl carrier results in to and from movement of the feed pawl. The pawl carrier is coupled by a torque responsive coupling to an oscillatory shaft which in turn is coupled through a gear train to a rack on the applicator ram. Reciprocation of the ram results in oscillation of the shaft which in turn results in oscillation of the pawl carrier. The amplitude of oscillation of the pawl carrier, and therefore the limits of the feed stroke of the feed pawl, are adjusted by means of a fixed stop which is on the applicator frame and movable stops which are on the pawl carrier. The torque responsive coupling permits overtravel of the shaft relative to the pawl carrier.

Abstract: A method and apparatus for changing dies on a moving bolster for a press including a control circuit in combination with a cam-actuated deceleration valve. A ramp is located at a predetermined location along a path for the moving bolster. Upon reaching the ramp location when the bolster is moving toward the press, the deceleration valve is actuated to inhibit and shut off a flow of air to air-operated motors on the bolster. Thereupon, the moves to a stop at a predetermined location relative to the press.

A two-fold adjustment is possible by mounting each cutting blade on an upper section of an insert mounted in a recess of a support or support ring sector. The upper insert section is secured to a lower insert section. The lower insert section is radially adjustable. The upper insert section is axially adjustable. Each adjustment can be made independently of the other adjustment.
