and Within the same upon the Wall 45 is seated a spiral compression spring 47, which is compressed against the cartridge B, as
the cap 41 screw threads in place'upon the body 10, from the position shown in' Figure 1, to the position shown in Figure 2, for the purpose of forcing the cartridge B in a piston-like action against the plunger 15, in order that the stopper 31 will be moved into the cartridge and permit `the ink vto iow through the passageway of the tube 15` and onto the distributor and pen point.
It is to be particularly noted that when the cartridge B is firmly seated in place u on the barrel, the tapered neck end `thereof as been forced by the compressed spring 47 into the yieldable gasket material a leak-proof connection therewith, preventing leakage of ink into the barrel and along the tube 15, since it is noted that When fully seated the extreme edge of the end 29 of the cartridge lies spaced fromthe Wall 14, and which space is illed by the packing material 18 surrounding the tube 15 in a leak-proof Contact.
Various changes in arrangement of parts may be made to the form of invention herein shown and described, Without departing from the spirit of the invention or vthe scope of the claim.
