Abstract

414,929. Reservoir pens. WADE, E. E. S., 13, Hope Street, Liverpool. Oct. 28, 1933, No. 29959. [Class 146 (iii).] A self-filling reservoir pen of the kind provided with an air tube of small bore extending from an ink passage in the feed-bar into the reservoir, and co-operating with means for varying the pressure in the reservoir, comprises a barrel divided into two sections a, a<1> detachably connected by a flush tubular member g, a rubber ink sac e substantially filling the barrel, and an air tube f extending from the feed-bar c into the sac e; filling is effected by removing the barrel section a<1> and repeatedly collapsing and expanding the closed end e<1> of the sac by finger manipulation. The air tube f fits in a central passage c<1> in the feedbar communicating through a lateral duct c<3> with the feed channel c<2> in the feed-bar. The sac e may be attached over a reduced extension b<1> of a push-in nib section b, or may have a beaded end clamped between an annular shoulder in the barrel and a washer above a screw-in nib section, or a flared end clamped between a correspondingly shaped shoulder and washer.
