摘要： Two different eccentric shaft portions are formed on a secondary shaft. A contact plate has two different contact portions which are selectively brought into contact with two eccentric shaft portions of the secondary shaft. The contact plate is attached to a guide sleeve. A plunger is slidably coupled in the guide sleeve. A saw blade, attached to a front end of the plunger, causes an orbital motion according to a phase difference between two eccentric shaft portions regardless of attached direction (i.e., normal or upside-down) of the saw blade.

摘要： A counterweight is provided to cancel axial vibration of a plunger of a saber saw. Swing rollers, rotatably supported at both ends of a roller shaft provided at a rear end of the plunger, interpose between a pair of opposing tracks formed in an axially elongated groove formed on the counterweight.

摘要： A saber saw includes a housing. A motor is contained in the housing. A second shaft is rotatably connected to the housing, and is rotated by the motor. A plunger connected to the housing is used for holding a saw blade. The plunger is free to reciprocate. A motion converting mechanism provided between the second shaft and the plunger operates for converting rotation of the second shaft into reciprocation of the plunger. A guide member is connected to the housing, and has a track surface. The plunger is moved along the track surface of the guide member during reciprocation of the plunger.

摘要： An attachment for a reciprocating saw comprises an offset member mounted on the drive head of the saw and comprising a lateral extension which holds a saw blade clear of the saw body The attachment also comprises a guard member having a planar surface adapted to engage a wall, and a slot through which the saw blade extends. The guard member is pivotally mounted on the saw body at a point spaced from the drive head. The attachment facilitates making a saw cut in a surface adjacent an inside corner.

摘要： A scroll saw including an adjustable tensioning mechanism is disclosed. The saw includes a housing having an inner surface and a pivoting arm having a rearward end disposed within an opening in the housing. A first blade clamp is disposed at the forward end of the pivoting arm and secures the upper end of a saw blade. The lower end of the saw blade is secured in a second blade clamp disposed at the forward end of a lower arm. A wedge is disposed within the housing, in contact with the inner surface of the housing. The wedge also is disposed in contact with and translatable along a surface of the pivoting arm. A rod is linked to the wedge at one end and extends through the pivoting arm. The rod includes an upwardly turned arm. A cam having a spiral track is rotatably mounted at the front of the pivoting arm with the upwardly turned arm disposed in the track. Rotation of the cam causes the track to move along the upwardly turned arm, further causing the rod and wedge to move forwardly, with the contact between the wedge and the inner surface causing the wedge and the rearward end of the pivoting arm to pivot downwardly, and the forward end of the pivoting arm to pivot upwardly to increase the tension of the blade.

摘要： A pneumatic power cutting tool is constructed to include an eccentric shaft, the eccentric transmission shaft having a first eccentric shaft and a second eccentric shaft eccentrically forwardly extended from the first eccentric shaft and adapted for reciprocating a cutter blade to cut the workpiece, a sliding block coupled to the first eccentric shaft by coupling means and adapted for sliding in a longitudinal sliding way in reverse to the reciprocation of the cutter blade to balance the centrifugal force due to the reciprocating motion of the cutter blade with the second eccentric shaft and to reduce the production of vibration and noise.

摘要： A fuel injection diesel internal-combustion engine, having a fuel injection nozzle and having a spring chamber for the pressure spring acting upon the nozzle needle. The spring chamber is constructed as a closed chamber without a leak oil connection and forms a space which is under a fuel pressure. The spring chamber fills with fuel, by way of a slide guide for the pressure linkage of the nozzle needle constructed as a throttling point. As the fuel pressure in the spring chamber rises above an operating pressure corresponding to the control position of the injection pump for the defined driving condition, the delivery time of the pump is prolonged for compensating the lowering of the injection quantity connected with the pressure rise in the spring chamber.
