摘要： A lubricating system for a heavy-duty material processing shears provides lubricant to one of more wear surfaces on one or more wear portions in the shears. The system includes a hydraulic lubricant pump that is actuated by the main hydraulic control system by means of which the jaws of the shears are opened and closed, and may include a sequential valve to distribute lubricant to various wear portions in sequential fashion. The lubricating system may lubricate one or more wear surfaces of the lateral blade stabilizers, primary and secondary blade(s) on the upper and/or lower jaws, pivotal connections between jaws and/or between the upper jaw and the hydraulic cylinder, a forward wear plate, or any other wear portion of the shears. The lubricating system may be retrofitted onto a conventional non-lubricated shears by replacing a conventional upper jaw with an upper jaw with lubricant conduits and a lubricating system.

摘要： A hand-held cutting tool for removing encapsulant surrounding a fiber optic cable splice includes a pair of saw-tooth edged scissor blades, coupled through a gear and drive shaft to a motor included within the tool. When activated, the gear functions to move the pair of blades back and forth, resulting in a scissor motion of the blades sufficient to cut through and remove encapsulant surrounding an fiber optic cable.

摘要： A branch cutter tool (1) having two blades (11,12) that are movable in relation to each other, of which one blade (11) is rigidly connected with a housing (2) and the other blade (12) can be moved by an electric motor (5) via a threaded spindle (8), a threaded nut (21) arranged on the threaded spindle and a rod assembly connected to the threaded nut. The blade (11) has an extension (13) projecting into the housing (2) and the threaded spindle (8) is rotatably supported by means of a rolling bearing (31) which is fixed to the threaded spindle (8) and is axially supported in a recess (17) formed into the extension (13) such that the cutting forces taking place in a cutting operation are absorbed by the components involved so that the housing (2) is not subjected to stress by these forces. The tensile forces transferred to the threaded spindle (8) when the movable blade (12) is closed are applied to the extension (13) via the rolling bearing (31). Furthermore, a force acts upon the extension in the opposite direction in the region of the bearing support of the movable blade (12) so that these forces thus cancel each other out and a closed power flux results.

摘要： A hedge trimmer includes a motor and a cutting mechanism driven by the motor. A clutch mechanism is interposed between the motor and the cutting mechanism. A first and a second handle are provided to be grasped with both hands of an operator. A clutch control mechanism is provided for connecting and disconnecting the clutch mechanism. The clutch control mechanism includes a first and a second switch lever which are associated with the first and second handles, respectively, and which are operable by the operator between a first and a second position, respectively. A pin is operably connected to the first and second switch levers and is movable between a connecting position for connecting the clutch mechanism and a disconnecting position for disconnecting the clutch mechanism. Biasing members serve to hold the pin at the disconnecting position when at least one of the first and second switch levers are at the first position. The biasing members permit movement of the pin from the disconnecting position to the connecting position when both the first and second switch levers are moved from the first position to the second position.

摘要： A portable, power-driven machine for cutting a threaded rod to any required length by the shearing action of a movable cutting bit thrust past a fixed cutting bit. Each cutting bit has a series of semicircular internal threads for mating engagement with the threaded rod, and a cutting face disposed perpendicular to the axis of the internal threads. A depression with a depth less than the thread pitch is formed in the cutting face of the fixed cutting bit. When the threaded rod is sheared, to one rod section is partly received in the depression at the end of the cutting stroke of the movable cutting bit, in order to prevent the jamming engagement of the movable cutting bit with the rod section through their mating threads. A similar depression is formed in the cutting face of the movable cutting bit in an alternate embodiment of the invention.

摘要： A portable electric tool, such as, for example, shears or secateurs suitable for pruning and/or harvesting work, comprises at least one moving working component disposed at the front and of a hollow frame one part of which forms the handle of the tool and inside which are housed an electric motor and a speed reducer. The outlet of the speed reducer is connected to the moving working component by means of a transmission system which comprises a moving gear unit. The tool also includes a trigger which protrudes outside the frame and operates an electric control device. The trigger and the electric control device are connected to the moving gear unit of the moving working component and follow the movements of the component. The trigger and the control device can occupy different relative positions, so that each movement made by the trigger from a neutral position, activates the control device, which in turn starts the electric motor to move the whole unit: i.e. the moving gear unit, the trigger, and the control device which then returns automatically to the neutral position at which the trigger is immobilized either by the limit stops, or manually.

摘要： In a reciprocating blade for cutting sheet material first and second side surfaces inclined relative to one another intersect to define an elongated cutting edge. The cutting edge is offset from a reference plane located midway between the side faces of the blade so that the first side surface passes through the reference plane in going from its associated side face to the cutting edge. At least the first side surface is covered with a thin coat of hard material harder than the base material of the blade. During use the second side surface is ground to cause the cutting edge to be defined by the hard material covering the first side surface. As a result of repeated sharpening grindings of the second side surface the cutting edge gradually moves to and then beyond the reference plane to give the blade a long useful service life.
