Combustion-powered tool with sleeve-retaining lockout device

Abstract:

The present disclosure provides various embodiments of a combustion-powered-fastener-driving tool that include a lockout device to ensure the tool's valve sleeve doesn't move to an unsealed position and the tool's combustion chamber remains sealed until the piston returns to the pre-firing position. The lockout device is engageable with a lockout device engaging member operably connected to the tool's trigger, which gives the operator direct control over locking the valve sleeve in the unsealed position.
