ABSTRACT:
The present invention is an accessory useful in servicing capillary tube type ink pens associated with strip chart recorders and the like. The device can be used to insert an air bubble into the metallic capillary tube pen during periods of nonuse, flush the pen with solvent when necessary, and prime the pen with ink from an ink supply. The device comprises a container for holding a quantity of ink solvent and having an air pump means such as a bellows communicating with the area above the liquid in the container whereby pressure or vacuum can be applied to the interior of the container. A base member communicates with the liquid in the interior of the container and has an extended tube contained therein terminating at the opposite end in an opening containing a bushing designed to snugly mate with the tip of the recorder pen to provide an airtight/watertight seal.
