Abstract: The system includes a grease pump assembly connected to a conduit having a grease outlet adjacent an endless chain of the chainsaw. The method includes pushing the grease toward the grease pump, pumping the grease, and feeding the grease between the endless chain and the guide bar. The pumping of the grease can be done automatically upon detecting an activation of the chain saw.

Abstract: A food product slicer includes a base and a knife mounted for rotation relative to the base. A slide rod extends in a direction past the knife. A carriage assembly is mounted for reciprocal movement back and forth past a cutting edge of the knife. At least one bearing arrangement connects the carriage assembly to the slide rod to facilitate the reciprocal movement of the carriage assembly. The bearing arrangement includes a lubricant reservoir. A bearing bracket holds a bearing that rides on the slide rod. The lubricant reservoir is fluidly connected to deliver lubricant to the slide rod in proximity to the bearing.

Abstract: A motor-driven portable chainsaw of the sort that includes a power source enclosed in a casing and a cutter device comprising a toothed chain and a chain guide. The saw being characterized in that the power source is a brushless direct-current electric motor controlled and switched electronically, with a rotor with magnets. A handle for holding and operating the saw is located underneath the motor assembly which supports the chain guide and includes said direct-current electric motor.

Abstract: A cutter for cutting a workpiece while using a water includes a housing, an electric motor disposed in the housing, a rotation shaft, a base, and a splashboard. The rotation shaft is supported by the housing for rotatably supporting an end tool driven by the electric motor. The base supports the housing, and has a top surface and a bottom surface to be in contact with the workpiece. The end tool has a part protrudable from the bottom surface. The splashboard section is positioned on the top surface and behind the end tool in a cutting direction. The splashboard section protrudes in a direction away from the top surface and extends in a direction substantially parallel to an axial direction of the rotation shaft.

Abstract: Chain saw featuring an endless cutting chain (5), mounted turning around a drive sprocket and a guide bar (6) equipped with a guide rail, a motor (8) driving this cutting chain, through the intermediary of said sprocket, a storage tank (11) of a lubricating fluid, as well as a pump (13) impelling the lubricating fluid towards the guide bar/cutting chain assembly (5-6), from the storage tank (10), characterized in that said pump (13) is coupled to an electric drive motor (13a) which is independent of the motor (8) driving the cutting chain (5).

Abstract: A gearbox is provided for a handheld power tool. The gearbox includes a housing including a recess having a wall section, a main gear disposed within the recess and including a plurality of gear teeth, and a drive gear engaged with the main gear for driving the main gear. The gearbox also includes means for retaining lubricant within the housing for improved retention of the lubricant on the main gear. The means for retaining is configured to create a localized pressure reduction within the housing during operation of the power tool. In one example, a portion of the wall section curves towards the main gear, and a localized pressure reduction is formed proximate the minimum distance between the curving wall section and the main gear during operation of the power tool.

Abstract: A slotter capable of providing a cut of precise depth into a tube is comprised of a main base and an adjustable roller base capable of extension and retraction from the main base, controllable by an adjustable over-center actuator linkage. A pair of roller sets securely hold the tube within the device. A cutting blade, straddled by a pair of limiting rollers, cuts into the tube. Cutting blade rotation is provided by a pneumatically powered rotational motor.

Abstract: The drive mechanism for imparting reciprocating movement to the tool plunger includes first and second drive members. The first drive member is mounted on an eccentric formation which is in turn mounted on a drive shaft thereby to impart a wobbling movement to the first drive member. The second drive member is in the form of a piston mounted for reciprocating movement within a bore formed in the first drive member. The second drive member is pivotally connected to the plunger. The second drive member has a helical groove in its exterior surface. A lubricant is forced along the groove in part due to the reciprocating movement of the second drive member in the bore of the first drive member.
