Abstract
1,176,193. Reservoir pens. PAPER MATE MFG. CO. 4 Aug., 1967 [8 Aug., 1966], No. 35899/67. Heading B6P. Means for increasing the air pressure in an ink reservoir to cause the ink to flow towards the writing point comprises an assembly 20 insertable in the rear end of a reservoir, particularly a ball-point pen reservoir 12. The assembly 20 comprises a hollow cup-shaped adapter 22 with a port 28 in the bottom thereof, and a loosely fitting piston 50 with a stem 52 which extends through the port 28. A spring 60 biases the piston outwardly so that ears 58 formed on the stem 52 abut the rear surface 26 of the adapter. A rubber washer 70 positioned between the piston and spring 60, seals against a shoulder 40 when the piston moves inwardly, thereby compressing air in the chamber 36 of the adapter 22, which high pressure air communicate with the interior of the reservoir 12. Inward movement of the piston is limited by the shoulder 56. In an alternative embodiment (Figs. 4 and 5), the chamber 36 is defined by a compressible tubular sleeve (70a) which radially deforms to reduce the chamber volume when the piston moves radially inward. Movement of the piston 50 is achieved with the normal writing pressure exerted by the user. The reservoir 12 may be used in a non-retractable or retractable pen. With a retractable pen (Fig. 1), the retract spring (5) is weaker than spring 60. Specification 1,058,098 describes in detail the retracting mechanism shown in (Fig. 1).
