A four-stroke internal combustion engine is provided that is capable of use in many power tools, including those power tools subjected to tippable applications. There is provided within an engine housing an oil reservoir and a valve chamber which independently communicate with a crank chamber. A strategically placed divider and passageway, located within the engine housing, appropriately direct lubricant within the engine housing so that the internal cavity of the engine is lubricated during use in various operating attitudes, and so that the fluid flows to and is held in the proper chambers of the engine housing during storage. There is also provided a breather arrangement for an internal combustion engine which includes a cam shaft having a hollow passageway in communication with the crank chamber and the air intake system of the engine.

A swim stroke exercise device including an adjustable resistance mechanism is provided. The resistance mechanism is attached to one end of the exercise device and includes a roller assembly having a roller clutch and a drive shaft extending from one end and a spring rewind assembly attached opposite the drive shaft. The drive shaft supports a drive pulley including a number of concentric engagement areas having different diameters. Adjustably disposed above the roller assembly, a resistance device includes an output shaft terminating in a mag pulley opposite the resistance device formed similarly to the drive pulley with a number of concentric engagement areas having different diameters that are aligned with the engagement areas on the drive pulley. The concentric engagement areas allow a belt trained about the pulleys to be moved to various positions on both the drive pulley and mag pulley to increase or decrease the amount of resistance provided to the drive shaft by the clutch. A separate adjustment mechanism is also connected directly to the clutch to vary the resistance provided by the clutch. An elongate member is attached to the roller assembly and is pulled to simulate a swimming motion against the resistance provided by the resistance device and the spring rewind assembly. When pulling ceases on the elongate member, the spring rewind assembly retracts the elongate member without interference from the resistance mechanism due to the roller clutch.

A tool for performing lopping, pruning and similar operations includes a housing assembly formed of a pair of telescoping tubular sections. The tool also includes a tool head, a head line and an actuating line. The tool head, which is connected to one end of a tubular section, preferably includes a spring-biased blade coupled to the head line which is connected to a slidable block. The actuating line, while engaging the slidable block so that tensioning the actuating line causes movement of the blade, is also slidable relative to the block upon relative movement of the tubular sections.

The invention is an apparatus having opposed jaws remotely located at a distance from actuator for the jaws. In particular, the apparatus has opposed jaws supported rotatably with respect to the actuator for the jaws. More particularly, the apparatus is a cutting device having opposed jaws located remotely and rotatably with respect to the jaw actuator for lopping limbs.
