  • Patent number: 8661953
    Abstract: A trimmer to cut a backing on which an overlay is mounted. The trimmer includes cutting blades and a removable fence that has a stop. The fence is carried by a pair of risers that are capable of moving relative to the work surface. A rotatable lever arm is coupled to the risers by a linking cam rod. When the lever arm and linking cam rod are rotated in a first direction, the risers move upwardly from the work surface and the stop of the fence is lifted upwardly and off the work surface to create a gap that enables the backing to move past the fence to the cutting blades to be trimmed. When the lever arm and linking cam rod rotate in an opposite direction, the risers move downwardly toward the work surface, and the stop is lowered against the backing to prevent the overlay from moving to the cutting blades.

  • Patent number: 8156851
    Abstract: This invention includes a system for cutting food products, such as potatoes, into proportional length pieces. In a one embodiment, the system includes a cutting assembly, sensors upstream of the cutting assembly and a programmable logic controller. The cutting assembly preferably includes a housing defining a passageway, at least two separately actuatable stops extendable into the passageway to provide an abutment to hold the food product in place, and at least two separately actuatable blades for slicing the food product into pieces. The controller cooperates with the sensors to determine the length of each food product and, based on a length determinative algorithm, selectively actuate one of the stops and at least one of the blades to determine how many times the food product will be sliced and location of the cut(s) relative to the leading end of the food product.

The cutting system includes a frame that supports a first saw assembly for cutting at one end of the workpiece and a second assembly for cutting at the other end of the workpiece. The first saw assembly supports a stop having an up position (non-cutting position) or a down position (cutting position). For measurement purposes, the one end of the uncut workpiece is placed next to the stop in the non-cutting position and during the cutting operation the stop moves below the workpiece. The cutting system also includes a first clamp connected to the first saw assembly and a second clamp connected to the second saw assembly or the frame. The first and second clamps have either an opened position or closed position. The workpiece is secured when the first and second clamps are in the closed position. The closed position also enables the operation of the first and second saw assemblies.

  • Patent number: 4548114
    Abstract: A cylindrical body resembling a piece of pipe has the sharp edge of a utility-knife blade extending into the bore of the body to cut a longitudinal slit in the wall of a piece of plastic tubing that is pushed or pulled through the bore. A removable stop protruding into the bore momentarily stops the piece of tubing until another utility blade, connected to a guide and handle positioned at an angle across the cylindrical body, is pulled into the slitted end of the tubing to cut on a line that intersects the longitudinal slit. A pointed angular piece is thereby cut out and removed to leave in the end of the piece of tubing a notch with a surface slanting outward toward the end of the piece of tubing for functioning as an inclined plane to spread the tubing. A linkage connected between the angular guide and the stop removes the stop to permit completion of slitting. A handle with a triangular blade is also connected transversely to the cylindrical body for cutting the slitted tubing into lengths.

    Abstract: The apparatus comprises a wheel-mounted frame on which engine driven hydraulic pumps are mounted to provide hydraulic power. Extending from the side of the frame is a live deck for transporting logs transverse to their length. A longitudinal conveyor receives the logs from the live deck and transports the logs to a retractable stop to establish the length of a firewood block. A saw adapted to transversely cut the log is arranged to be lowered to cut the block from the log. A guard encloses the saw and supports clamps that clamp the log on each side of the saw during cutting. The retractable stop is retracted from the log end as the guard clamps the log for cutting. Following cutting the cut block is directed to a centering device which centers the block relative to a hydraulic actuated ram and fixed splitter blades. The block is split when forced across the splitter blades by the ram. A kicker rejects log remnants to a reject conveyor. Unsuitable blocks are rejected to the reject conveyor.

  • Patent number: 4269095
    Abstract: A stop mechanism for facilitating the cutting of an elongated workpiece into a large number of equally sized pieces with a radial arm saw. An elongated rail extends perpendicularly beneath the arm to serve as a guide for the workpiece as it is fed into the saw from the infeed side to the outfeed side of the table. An elongated infeed guide which is parallel to the rail spaces the workpiece from the rail as it is fed into the saw. A stop mechanism includes a housing which is secured to the outfeed side of the table and a plunger which moves toward the rail in an extended position and away from the rail to a retracted position. As the workpiece is guided toward the outfeed side of the table, the end of the workpiece contacts the extended plunger thereby terminating further infeed. The workpiece is then cut with the saw, and the plunger is momentarily retracted to allow additional infeed of the workpiece. The end of the workpiece for the next cut then abuts the extended plunger.

  • Patent number: 3949630
    Abstract: Battery grid plate castings are trimmed in a two-step operation. Each plate moves flat along a horizontal or inclined path against a first stop bar. One of two trim blades on a reciprocating upper die block then shears flashing from the leading end of the plate during a downward stroke of the die. Then the stop bar raises during the upward stroke of the die, and the plate moves forwardly against a second stop. Upon the next downward die stroke the second trim blade shears flashing from the trailing edge of the plate. During the next upward stroke, the fully trimmed plate moves forwardly onto a stacking device. As the leading end of one plate is trimmed at the first trim station, the trailing end of a preceding plate is trimmed at the second trim station. The second stop is easily moved to different stop positions along the path of travel of the plates to change the distance between such stop and the second trim blade and thereby enable trimming plates of different lengths without changing dies.
