A combustion nailer includes a tool housing, a combustion source disposed at least partially in the housing and including a valve sleeve reciprocating relative to a cylinder head along a tool axis between a rest position and a pre-firing position, a fuel cell chamber in the housing in operational proximity to the combustion source and dimensioned for accommodating a fuel cell, at least one pivot point associated with the fuel cell chamber transverse to the tool axis for facilitating movement of the fuel cell between a non-activated position and an activated position, and at least one actuator pivotable about the pivot point and engaging the valve sleeve at a point closer to the tool axis than to the fuel cell chamber such that movement of the valve sleeve from the rest position to the pre-firing position causes movement of the fuel cell from the non-activated position to the activated position.

Fuel cell actuation mechanism for combustion-powered tool

An adapter configured for use in combination with a cap on a fuel cell having a closure formation, the cap having at least one leg portion and a corresponding foot extending from the leg, including a ring portion configured for engagement upon the closure formation of the fuel cell and including a top edge, a bottom edge, and a sidewall therebetween having an inner sidewall and an outer sidewall, a grooved portion defined by the inner sidewall, a convex gripping formation on the outer sidewall complementary to the closure formation, and at least one recessed formation adjacent the grooved portion for receiving the foot.

Interchangeable adapter for in-can and on-can fuel cells

An adjustable depth of drive assembly for use with a fastener-driving tool includes a workpiece contact element having a contact end and an adjustment end, at least one stop configured for being secured to the tool and being normally moveable between an adjusting position in which the workpiece contact element is movable relative to the tool, and a locked position where the adjustment end is secured from movement relative to the tool, and at least one biasing element associated with the stop and configured for urging the stop and the adjustment end into a selected locked position relative to the tool without the use of tools.
