Abstract

335,941. Vivian, G. S., and Valentine & Sons, Ltd. July 3, 1929. No Patent granted (Sealing fee not paid). Reservoir-pen caps.-The cap of a reservoir or stylograph pen contains a concentric tubular portion adapted to enclose the nib or style and to be inserted into the front end of the barrel to hold the cap in place. The tubular part 4 is spaced from the internal wall of the cap and is adapted to engage by means of screw-threads in an annular space formed in a bell-shaped end 5 of the barrel or nib-section and to form an ink-tight joint. The part 4 is preferably formed separate from the cap and is screwed into place through a part 7 of reduced diameter inside the outer shell 2 of the cap. The internal part may be formed integral with a head closing the end of the cap, or a cap 11 may screw on to the outer end. An annular part of a pocket clip 10 may be gripped between the end of the part 2 and the closing-cap. The outer part 2 of the cap may be formed of a number of tubular elements a, b, c, between any adjacent pair of which the clip may be gripped. The dimensions of the parts 2, 4, and 5 are such that the nib is prevented from entering between the walls of the parts 2, 4. Specification 334,570, [Class 43, Fastenings, Dress], is referred to.
