FOUNTAIN REIN.'y

The present invention relates to improve-V ments in writing implements and has particular reference to an improved fountain pen.',` 1.

-Animportant object of the invention resides in the provisionof a fountain pen of simple and durable construction and which lmay be conveniently manipulated for replenishing the supply of` writing liquid.

A further object of the invention is the provision of a fountain pen-of the above character designed so that the -filling operation may beV effected by rotary movement` ofan end block mounted thereon.

A still further object of thel invention is the provision of a fountain pen formed So as to permit' convenient re-placement 'of the reservoir .and 'f disconnection for cleaning,

Still another object of the invention is the provision of a fountainpen of the `above type which will beecientin4 operation and Y which maybe manufactured at a relatively low cost.` .j 1

Other objects and advantages of theinventionwill become apparent as thedescrip-v tion progresses p In the accompanying drawing forming a part of this specification'and in which rlike lreference characters areemployed todesignate ycorresponding parts throughout the same:V i i Figure 1.. isa 'longitudinali sectional View through a fountain -pen constructed in ac- Figure 2 is a side elevational view of a detailed structure forming part of the improved pen, j

Referring to the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 10 generally indicates the penbody yorbarrelV which isof hollow cylindrical form tapering slightly vat its ends in the customary manner.

Formed Yadjacent the lower or forwardend of the barrel are exterior screw threadsffll adapted for threaded engagement with a' dust Y lower end rportion "of the' barrel n,

vis'interiorly screw threaded for connection with a co-acting member. as will later appear. Formed adjacent the `upper or rear end of y the barrel in the` interior periphery thereof is f i an anmilargroove 12,'the purposeofwhich gresses.

. will become-apparent as the description pro- Formedfor connection with thelowei' end y i of the barrel is a substantiallycylindrical pen section sleeve 13, the outer contour being arranged A to symmetrically conformVV to the tapered formation of the shank 14 exteriorly screw threaded for engagement with the interior threads of the barrel. "As isusual, this sleeve formed with alongitudinal bore in which Yisvtightly Vfitted a feeder. sleeve 15 and on the outerV end of which is formed a feeder duet 16. As shown to advantage inFigures 1 and 2, apen nib 17 is detachably mounted in the lower end ofthe sleeve in contact with the vfeeder duct 16 so that the liquid is constantly fedto thepen.- f .1.

Rigidly mounted in the lower-portion of the pen barrel in a centrally disposed posiso Y tion is a conducting tube 18, the lower end thereof being' tightly fitted inthe bore of the sleeve tomaintain the ytube in position: This tube communicates with the feeder sleeve 15 sothat the writing fluidv maybey conducted through the' sleeve and duct 16. i 1

, Mounted on the :upper or rearend of .the .barrel 10.for rotatable movement is an end block 19' designed to conform to the contour #of the barrel and'provided with an inwardly projecting cylindricalv shank k2O adapted for slidable engagement with the interior ybore of the barrel. Thisshank is formed with an annular groove 21 adapted to be disposed in feo co-acting relation with the groove 12 Vformed in the barrel vin operative position.- Theblock is secured against longitudinal displacement f cular in cross section'and inserted -for engagewall` of thebarrel. This will permit convenient rotary movement of the block rela.

`tive tot-he barrelv but Willobviate the possi? bility of longitudinal displacement of these VAs illustrated' in Figures 1 and 5,

' by means of a iiexible retaining band 22,.cir.

the block is formed with a longitudinal bore v ,23,substantially rectangular in vcross sect-ion f extending through the 'majorvportionof the lblock and communicating with theinnertendf V l f of the barrel.

An important characteristic of the present invention resides in the provision o1 a cylindrical holloW reservoir 23a preferably formed of rubber or similar material forming a ilexible 'tube or sac and designed to contain Writing ink orA similar liquid. The lower end of the reservoir 23a is formed to provide a reduced neck 24 Which is securely attached in the here of a circular ring 25. This ring is formed so as to be tightly lit-ted Within the bore of the barrell() and disposed in a central position in :the barrel. The upper end of the sac 23L is closedfand of rounded formation. Secured to y this rounded end of thesac is a longitudinally rprojecting ar1n26 of rectangular cross section adapted for slidab'le engagement with the longitudinal bore 23 formed in the block 19. One 'end of the arm 26 is formed with a sub,-

'stantially semi-circular cap27 arranged so as to be suitably fitted over the rounded end of the sac and secured'thereteby adhesive in any suitablemanner. The intermediate portion of lthe arm 26 is provided with a transversely extending inortise 28 adapted to be disposed in transverse alignment with `transverse bores 29 `iormed in the block. These bores are arranged :to slidably receive therein a pin 30 by means .of which the arm 2G is secured Within the block. p

Frein the foregoing description it will be obvious that the upper end oitl the conducting tube 18 may be tightly fitted Within the bore of the annular ring 25 so that a continuous conduit from the sac 23:L to the pen nib 17 is produced. To lill the sac 23@ and replenish the supply of writing'liquid the block 19 is rotated while'the'barrel '10 is held instat-ionary position. This action of the block will twist .the sac .23L in spiral form so "that the liquid as Well as thevairftherein Will be expelled t0V form a partial vacuum with the sac. The pen nib and feeder duct 16'are immersed in the Writing liquid and the block 19 rotatably actuated to its initial starting position, This will cause the Writing liquid tobe drawn through the Vconduit into the `sac andsubstantially till the same. Thus, the'filling operation maybe accomplished with facility andV convenience. Ilurthermere, the assembled parts of the pen may be readily disconnected for cleaning or repiacen'ient of parts.

1t is to be understood that the form oi my invention herewith shown and `described is to be taken as apreiferred example ofthesame and .that various changes .as to .thesha'pe',' size and arrangement ot parts may be. resorted to Without departing from 'the spirit lof the invention or scope ot' the subjoinedelaim.

Having thus described Viny invention, I
