Abstract
An automatic BX cable cutter including a cable guide and clamp, a circular saw carried by a floating pivoted carriage actuated between cutting and inactive positions by a cam, the machine being so electrically coordinated that, when the saw motor is started and the cable end is inserted into its guide to a pre-set stop point, the clamp screw moves to cable-holding position, and the feed motor permits the carriage and saw to be raised to cutting position; after the cut has been made, the saw is retracted, the clamp screw drive is reversed and the cable is released.
Claims9
An armored cable cutting machine comprising, a base, cable guiding and holding means supported on said base, a carriage mounted on said base for pivotal movement about a horizontal axis, a circular saw carried by the carriage, a motor on the carriage for driving the saw, and carriage moving means including a carriage feed motor supported on the base, a cam on a cam shaft and driven by the feed motor, a toggle linkage system having one link journaled on the cam shaft and another link connected to the carriage, and resilient means cooperating with said links to bias the carriage toward cutting position.
An armored cable cutting machine comprising, a base, cable guiding means and cable holding means supported on said base, a carriage mounted on said base for pivotal movement about a horizontal axis, a circular saw carried by the carriage a motor on the carriage for driving the saw, and means for moving the carriage to bring the saw into and out of cable armor cutting positions, the cable holding means including a clamping screw and reversible driving means for driving the screw into and out of engagement with the cable at a point substantially opposite the cutting position of the saw.
An armored cable cutting machine comprising, a base, cable guiding means and cable holding means supported on said base, a carriage mounted on said base for pivotal movement about a horizontal axis, a circular saw carried by the carriage, a motor on the carriage for driving the saw, and means for moving the carriage to bring the saw into and out of cable armor cutting positions, the cable guiding means including a tubular element, two adjacent walls of which meet at an angle between 100.degree. and 170.degree., and means positioned to bias the cable toward the apex of said angle.
An armored cable cutting machine comprising, a base, cable guided and holding means supported on said base, a carriage mounted on said base for pivotal movement about a horizontal axis, a circular saw carried in a position adjacent the guiding and holding means, a motor on the carriage operatively connected to the saw, carriage moving means including a carriage feed motor supported on the base and toggle linkage connecting the feed motor to the carriage, and cable holding means including a clamping screw, a reversible motor supported on the base and a clutch between the reversible motor and the clamping screw.
