fa claims. (01.120-47) This invention relates generallyto pens; and more particularly to a novel and improved construction of a pen'of `the fountain type.

It is an object of this invention to provide/a :K pen of `the characterf described havingnovel and improved means for filling the same, which means will permit said pen to holda supply of ink substantially four times as large as that possible with pens heretofore used.

Another object of `this invention is to `provide in a pen of the character'described the novel and improved means for drawing asupply of ink into the same, said means being simple in operation and requiringonly a few parts which will not readily get out of order. A further objectof this invention is to provide a pen of the character described having novel and improved means for fillingjthe same, the

said means occupying 'aq comparatively small space within the pen barrel,` thereby. permitting the said barrel to hold a .relatively large `supply of ink and being constructed of only a few parts which will not become` inoperative and get out of order in use.' L, y

A` still further vobject of4 this invention isito providea,` pen of the character described comprising only a few parts which may be readily assembled and disassembled and which; ish provided with novel and improved means for filling the same in addition to novel and simplifie means for actuating said filling means.. i* A still further object of this inventionf is to provide a pen of the character described which will-be simple in construction comprising only a few parts readily assembled in operative position and which may beqproduced along lines convenient for low cost manufacture whileatthe same vtime vbeing highly `efficient for carrying out the purpose for which it is designed. i i.

`With the foregoing and other objects in `view `which appear as the description proceeds, the invention consists in certain novel features of construction, arrangement and1combination of lparts. hereinafter more fully` described, illustrated in the accompanying drawing and particularvly `pointed out in the appended claims-,it being understood that variousl changesl in the `form, "proportion, size and minordetails ofethe structure mayv be made without departing from the spirit-or sacricingany of the advantages ofthe invention.' I i 'y For the purpose Vof'facilitating an understanding of my invention, Iuhaveillustratedv in the accompanying drawing a preferred embodiment thereof, from an inspection of whichwhen consideredin connection withthe following description, my invention, its mode ofaconstruction., assembly and operation; and`- many of its advantages `should bereadily understood andappreciated.y .m

Said memberl extends centrally within, said barrel 10i and` is adapted for rotary movement therein as Awill behereinafter more The member 16. has'mounted thereon a piston generally designated bythe reference character 19, saidfpiston'consistingiof'a cylindrical member 20, the interior of which is hollow and may be filled with a resilient material 21 which will snugly encase the member 16 to prevent the passage of ink past the piston 19. In the end walls of the vmember 20 are provided suitable rectangular slots 22, as shown in Fig. 5, said slots being of a size and shape to permit the passage therethrough of the screw threads provided on the member 16.

The member 20 `is provided withlaterallly extendinghannulan flanges 23 and 24 between which is disposed the piston ring 25 formed from resilient material such as cork or the like. The

laterally extending annular flanges 23'form op-.. posed end abutments for the sleeve-likebody oi"l piston ring 25 which resist the tendeilcyoi'said member 25 to increase in lengthdue to radial, compression thereof whei'iinsert'din'the cyl-` By reason of this, .and byk inder or reservoir 11. reason of the fact that the body 25 is made of resilient material', the piston will nt snugly withinthe cylinderandseal the' same to prevent the passage ci inkipast: the-piston while permitting of the .reciprocati'orr loi :the pistonv within the pen barrel. It may be noted at this time that instead of' the resilientffl'llin'g 21. :provided within the. member` Zdftofpreyentfthe. passage of ink past thepiston, a plurality" of suitable washers of resilient material fhavingrectangularf openings' similar` tov the openings" 22 may be disposed within said member'. v20 lfoieffectivelyf preventing the. passage: oiii-inltlthrough theinterior. of the member 20.

The uppermostedg'e othefbarrel is .of reduced .diameter .asl Ashown at:r 31,.VV thereby formingv a shoulder;` 32...4 Adaptedtobei received over the ree lduced portion. .31 a cap member 33,v said cap member` being 'freely rotatable :son the reduced portion 31 for actuatingfthe.sorewmember 16m a mannerv vto benowd'escribed. 1 Loosely mounted within thev cap member 33v is an annular member v34 :provided with a dependa'- ingi internally :threaded portion 135.; which is adaptedto bethreaded in the openthreaded. end forthe'barrel` 10-. .The niember34 isfprovided with. a centralwopening 36, said-opening. being of' reduced diameter atits upper portion and is adapted to permitthepassage therethrough of :the member. 37,A which member has a threaded shank 38, the. freel end of` .which is :rigidly yand permanentlyusecured to the cap 33, as shown in 'Fg;,1, 1i;

The member 37 is'provlded witha rectangular head 'sdasfshown inFig. 3, which. head is adapted to be received between the-'bifurcations inthe end otthenscrewmember ld.'I The head 39,is,of such .a-size as tobereeeived within the enlargedpcrtion of thewopening 36 in the meinber 34, but is larger than the diameter of the reduced portion of said opening, whereby said head 39 will complete the assembly of the member 34 within the cap 33. As already stated, the cap 33 is readily rotatable relative to the member 34 and by reason of the head 39 of the member 37 engaging between the bifurcations of the screw member 16, the rotation of said cap 33 will impart rotary movement to the screw member 16.

As already stated, they screw member' 16 is swivelly mounted at its lower end in the nib end section 13, the reduced end 17 on said screw member providing an annular shoulder which takes the end thrust imparted to the end member 16 in one direction. The end thrust in the other direction is taken by the threaded shank 38 of the memberV 3'?.

In assembling the pen, the nib end section is screwed into one end of the barrel 10, the screw member 16 withitsI associated piston 19` being disposed within the barrel with the reduced'portion 17 thereof received in the opening 181 pro-'- vided in the nib end section 13. The ` members 27, 28 and 29 are then mounted in place, as shown in Fig. 1. The members 2-7 and 29 are provided with diametrically disposed recesses 40 and 41, respectively', whereby the same may be readily assembled in operative position'by reason of a suitable toolV having projections for disposition within said recesses. Similarly, the member 34V is provided with the recesses 42 which may be reached by a similar tool through the openings 43 provided in the cap portion 33 when it is desired to either assemble or disassemble the member 34 with the end of the barrel .10. A

-When the pen is completely assembled, as shown in Fig. 1,` it will be readily apparent that the 'rotation of the cap 33' will iin-part rotary movement to the screw member 16, which member is held against longitudinal movementr The rotary movement of the member 16 will in turn impart reciprocating movement to the piston 19 causingfthe same to move. either up or down depending upon the: direction of rotation; The nib end section 13 is provided with the-.openings 44.ior permitting the passage of ink into and out of the reservoir 11.3` A

When it is desired to ll the pen'with inkorother writing fluid, the nib end is inserted into an ink well with the piston in its lowermost position. Thereupon the pistonl is retracted to its uppermost position by rotation of the operating screw member 16l by means of the cap 33. VThis will draw the ink into: the pen'barrel. or reservoir llas will be obvious.y It will also be apparent that the rotation of the cap 33 in the opposite direction will cause the piston to descend toexpel the ink from the barrel should there beany in the barrel when that is found necessary or desirable.

As is customary, lthel body 10. of the pen will be preferably constructed of an opaque material, so that the construction of. the interior parts vare obstructed or concealed from view;l `The screw member 16 as well 'as the other metal parts which go to make up' the construction of my improved penl are preferably formed of-a non-corrosive material, and, if desired, may be made of some light alloy, such as aluminum. .or thelike, so as to be oa minimum weight.

The novel details of construction. and the combination and arrangement vof the parts of my improved pen result in anarticle having.' many 'i practical commercial advantages. It will be readily apparent that the structure may be quickly and economically manufactured, and by reason of the small number of parts may be readily assembled in a minimum of time Iby' heretofore used, and particularly over that of vio pens of corresponding size employing the conventional compressible rubber sack. l

It is believed that my invention, its mode of construction, assembly and operation, and many of its advantages should be readily understood from the foregoing without further description,

and should also be manifestthat while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation within the purview of my invention as dened in the appended claims.

What I claim and desire to secure by Letters Patent of the United States is:
