ABSTRACT:
An auto-pull follower is provided for use in a grease gun of the type having a grease reservoir with a piston mounted for reciprocating movement in the reservoir. The reciprocating piston is provided with a novel auto-pull mechanism comprising a spring biased spool mounted for rotation on the piston, and a flexible cord or chain extending from the spool and out of the reservoir through a hole in a rearward end wall of the reservoir. Pulling the end of the cord outside the reservoir causes the spool to rotate against the bias of the spool spring and causes a length of cord to be unwound from the spool. After unwinding the length of cord from the spool, continued pulling of the cord from the reservoir end wall causes the piston to move against the bias of a piston spring in a direction towards the reservoir end wall. The movement of the piston toward the end wall increases the interior volume of the reservoir and enables the loading of grease into the reservoir interior. Releasing the cord causes the spring bias of the spool to automatically retract the length of cord pulled from the reservoir interior back into the reservoir interior and rewinds the length of the cord back on the spool.
