An applicator/remover mechanism automatically applies and/or removes a clip, such as the so-called Safelok clip. Each clip applicator/remover mechanism preferably includes a workarm which is pivotable transversely towards and away from the longitudinal centerline of the rail, a clip applicator tool mounted on the workarm, and a clip retractor tool mounted on the workarm. The clip retractor tool includes first and second retractor arms pivotably mounted on a housing, each arm having downwardly-extending fingers to engage the side of a rail clip. The arms have intermeshing teeth which cause the second retractor arm to pivot upon pivoting of the first retractor arm to selectively pinch and release the rail clip. The resulting mechanism is capable of both applying and removing clips rapidly and efficiently while accommodating variations in position and orientation of the rail and/or the clips.

Mechanism and method for removing and/or applying transversely applied

A machine is capable of automatically applying and removing transversely applied rail clips such as the so-called Safelok-type clip. The machine preferably includes a workhead on which is disposed one or more applicator/remover mechanisms, each of which is capable of automatically applying and/or removing a clip. Each clip applicator/remover mechanism preferably includes a workarm which is pivotable transversely towards and away from the longitudinal centerline of the rail, a clip applicator tool mounted on the workarm, and a clip retractor tool mounted on the workarm. The resulting mechanism is capable of both applying and removing clips rapidly and efficiently while accommodating variations in position and orientation of the rail and/or the clips.

Apparatus and method for applying and removing transversely applied

A rail saw has a power head which includes a two cycle engine which does not require premixing of gasoline and lubricating oil. Instead, undiluted gasoline is stored in the engine's fuel tank, and lubricating oil is supplied to the engine's fuel supply system downstream of the fuel tank by a mechanical metering pump which delivers a designated, preferably adjustable, quantity of oil to the fuel supply system per engine revolution. In the case of a power head formed by converting a chain saw power head to a rail saw power head, the oil supply system may comprise the lubricating oil system originally designed to lubricate the chain saw's chain. Also disclosed is a preferred method of converting a chain saw power head requiring the storage of a premixed gasoline/lubricating oil mixture in its fuel tank to a rail saw power head whose fuel tank stores gasoline only.
