Patented Get. 30, 1923.
WILLIAM HfAVEB'ILL, 0F BOSTON, MASSACHUSETTS, ASSIGNOB 0F ONE-HALF T0 ARTHUR C. ERISMAN, F BROOKLINE, MASSACHUSETTS.
FOUNTAIN' PEN.
Application ined may 1a,
Spf Massachusetts, have invented new and useful Improvements in Fountain Pens, of which the following is a specification.
The present invent-ion relates to fountain ns and particularl to the means for filllng and refilling suc pens with ink.
The object of the invent-ion is, primarily, to enable the pen to be filled without either dipping the en`into ink 0r pouring ink into the barrel ofP the pen; and this object is accomplished by providing for the use of such pens a cartridge having stiff walls and adapted to be Sold to users already filled with ink and to be placed by the user in a pen and removed when empty to make room for a new filled cartridge.
Another object of the invention is to enable a close, non-leaking, packed joint to be made between the cartridge and the stock of the pen without need of especial care on the part of the user and without fail upon each charging of the'pen. This further object is accomplished b the use of a special stopper for the cartri ge and a special construction of the pen stock which punctures the stopper, the stopper being further so made as to form a yielding packing between the end of the cartridge and the penstoek.
For a complete illustration and explanation of the preferred manner in which l have carried my invention into practice, attention is directed to the drawings furnished `herewith in which there are illustrated three of the possible forms in which the essential characteristics of the invention may be embodied.
In the drawings,-
Figure l is a longitudinal sectional viewY on an enlarged scale of a pen embodying my invention.
Figure 2 is a view of the open end of the cartridge and a stopper for the same having the form and construction shown in Fi ure 1. 4
ike reference characters indicate the same parts in all of the figures wherever the occur.
Iii Figure'l the barrel is shown as made of two parts a and b which are detachably secured together by a threaded joint c about midway of the barrel. d is the stockwhich 1921. Serial No. 470.528.
carries the metal pen e and the leader f for ink by which ink is conducted to the en point, such stock having a threaded endp d which is detachably screwed into the end of the barrel. g is the cap which is placed over the-pen stock and pen and may be screwed on the barrel by complemental threaded parts g1 and a1 in the cap and on the exterior of the barrel, respectively.
As thus far described the pen does not differ from other fountain pens now known and used except in so far as the construction of the pen barrel in two parts is a departure from common construction; but this two part construction is not an essential of the invention, for all essentials thereof may be combined with a fountain pen having a one piece barrel. It is to be understood, also, `that any material suitable for fountain pen construction may beemployed in -making the pen as thus far described.
Within the barrel is a cartridge It containing ink, being closed at the end h which enters the closed end of the barrel, and being open at the other end but having a stopper therein. The cartridge may be made of any material which is sufficiently stiif to enableit to be handled without collapsing, to be inserted endwise into an open fountain pen barrel and to sustain the pressure applied as hereinafter described by the pen stock in puncturing its stopper. Materials suitable for the purpose are glass, metal, hard rubber, waterproof fiber or paper, and compositions of various sorts. In transverse dimensions and outline the cartridge is preferably made to conform as closely as possible with the ninside of the barrel and in length to extend from the closed end of the barrel to the pen stock, but being preferably enough shorter than this distance to admit a cushioning piece Z between the head of the barrel and the closed end of the cartridge. The stopper c has certain characteristics to which attention is called. It is formed with a flange k1 which overlaps the edge of the cartridge at its open end to form a packing between such end and the base of the pen stock d and it also has a transverse wall or web k2 which extends across and closes the entrance to the cartridge. This web is piercer is a channel n which extends froln near the point to its base and opens into the passage o throughv which ink is con# the stopper suicient bearing on the walls of the -cartridge to hold it. firmly seated, the stopper is made as a plug which enters to a substantial distance into the bore of the cartridge making contact with the inner surface thereof, but itis also recessed from one end'or the other, or permissibly from both ends, whereby the thickness of the web is reduced to a small fraction of, the axial length of the entire stopper.
In the pen stock' is vmounted a piercing point m which projects opposit'ely to the pen oint and is of such dimensions that it wi l enter the open mouth of the cartridge within the walls of the plug; and it is pointed and sufficiently stiff to A.be capable of puncturing and passing through the end wall k2 of. the stopper. In the sideof this ducted to the pen point.
A, filled cartridge closed by a stopper like the stopper Is maybe placed in the barrel of the fountain pen when eitherthe barrel is taken apart at 4the joint or the pen stock is removed. Then when the parts of the barrel are brought together, or when the pen stock is replaced, the approach of the barrel head' to the stock causes the piercer to enter the cartridge and pass through the end wall ofv the stopper, thusl establishing a channel from the interior of the cartridge 'to the pen poinJ Athrough supply of a pen made according to my in-.
which inkmay flow. When the stock is screwed tightly into the barrel and the parts of the barrel are screwed tightlytogether, the cushioning plug l, and the lip 1:1 of
the stopper are put under compression and the stopper lip is then caused toact as an elastic gasket between the stock of the pen and the end of the cartridge, packing the joint between those parts and preventing leakage of ink.
It will be readily understood from'the.
foregoing description that when the ink vention is exhausted, the supply may be renewed by removing the empty cartridge -and substituting a filled one. The substituted cartridge is' sealedand is dry and clean externally, while )the packed joint between the exhausted cartridge Vand the stock of the pen has prevented inkl from'l n liability of the pen becoming clogged withv sediment which exists when the supply is taken from an ink bottle.- l
What I claimand desire to secure by Letters Patent is:
1. A fountain pen comprising a barrel having a head at one end, a pen stockatf the other end having an inwardly projecting piercing point provided with an ink conducting channel, and an ink cartridge l adapted to enterxthe barrel and having 'one closed vend and one open end, a stopper penetrable b saidv piercing oint located 'in the open en of said cartri ge and formed Wi th a lip of resilient material overlapping the walls of the cartridge andadapted to be pressed -against the a jacent end of the pen stock, and a cushioning piece mounted in the barrel in position to engage the closed end of said cartridge and pressthe other end against the' pen stock. 2.
fountainpen as set forth in claim 1- and in which the stopper for the cartridge is a plug of rubber compositionfittin within the open end of the cartridge an having a bead which overlies the edge'of the latter, said stopper having a transverse closing Wall which is adapted to be penetrated by said piercing point.
In testimony whereof signature.
