NESTED SLEEVE RECORDING PEN HEAD

摘要

Special construction of a recording pen for use with capillary tubing in an inking pen system. The pen includes a stainless steel capillary tube terminating in the pen head construction which includes a removable recording pen tip made of a suitable material providing passage for flow of ink to a recording surface. The head includes several coaxial nesting sleeves cooperating to form a small head reservoir located immediately adjacent the pen tip. The end of the capillary tubing is secured to the pen head by bonding between the end of the capillary tubing and at least the outer one of the coaxial sleeves.
