Original yapplication led Janna! 22, 1919, Serial No. 272,480. Divided and this application filed4 May 21,

To all whom muy coma/,rn

Be it known that (animas A. lnx-n. :l lcitizen of the United States, and a resident of Toledo, in the county of Lucas and `ltate of Ohio, have invented aV certain new and useful FountainPen; and l do hereby declare the following to be a full, rieur, and exact description of ther invention, nue-h as will enable others skilled in the art to which it appertains to make and use the same. referenee being had to the aecoinpanying drawings, and to the diameters ofreferenee marked thereoin which form a part of this Spef-ileation.

This invention relates to fountain nene, and has for its primary object the pre sion of a novel construction of ther barrel tn ereof adapting it to be made of thin metal or other suitable material in place of the hard ruhher now commonly employed in the construction of fountain pen barrels. The invention, however, does not exclude the use of hard rubber hut is more paltienlarly direct-ed to a (construction which renders the use of metal practicable as a substitute for hard rubber,

A further object of my invention is the provision of simple and etfieient means for locking the several sections of the barrel in assembled relation.

The invention is fully deserihed in the following speeifieation, and while, in its broader aspect, it is capable of embodiment in numerous forms, one embodiment thereof illustrated in the aeeompanying drawing,

in whieln- Figure 1 is a central longitudinal section of a` 'fountain pen embodying the invention with parts in full. Fig. 2 is a cross section on the

line

2, 2 in Fig. l, and Fig. 3 is a ventral longitudinal seetion of a slightly modified form of the invention with the compressible ink hug omitted.

This applieation is filed as a division of the application fied by me January 22, 191%), Serial No. 272,480.

Referring to the drawings, and partienlarly to 1 and 2 thereof, l and 2 designate the iongitudinally alined rear and front end sections respectively, of the external shell. or casing of a fountain pen barrel embodying the invention, and 3 the internal reinforcing shell or easing thereof, which shells are tubular in form and may be of Serial No. 298,710.

thin metal or othersnitahle material. The interred eheil il is preferably longitudinally eorrngated to stiften its structure and thereby form a more rigid. reinforcement for the outer elheli.

The outer end 'of the rear section l is rlosed h r a plug l. whieh may lie of Stamped netal, und is inserted into the section from the inner end thereof and prevented from romplete passage therethrough b v eoaetiou with the tapered outer end portion of the' ser-tion and hv the inwardly turned end edge 5 thereof. 'lille inner shell 3 is intended to tit elosely within the outer shell sections i and 2 and is fixedly secured in the rear set= tion t by soldering or electric welding at dilferent points. as indicated at (3, or it may be seeured within the section l in any other suitable manner. The rear end of the shell Il ahnte against the alined inner edge portion of the end elosing plug 4 to firmly hold said plug to its seat in the outer end of the ser-tion 1. This plug may, however` he soldered or seein-ed in any other ,suitable manner in the section l.

The outer shell seetion has n turning lit on the inner shell 3 and is threaded to the forward end of the inner shell 3 at 7, The threads are preferably rolled in the

shell Sections

2 and 3 so as to forni each section with inner and outer threads, the adjavent threads of the two seetions being intended to interengage and the outer thread of the section 2 being provided for engageinent with the customary internal thread of an inelosing cap. The engaging threads of the two sections are so disposed as to permit an unserewing and removal of the outer section 2 :from the inner end., of the inner shell or section 3 away from the section 1.

The eustomary pen point carrying seetion 8 is threaded into the inner end of the Yshell Il and has the shoulder J at the base of itsl thread abutting againstthe adjacent ends of the inner and

outer shells

2 and 3, thus preventing e removal or unserewing of the shell 2 from the shell 23 until the pen carrying section S has been removed from engagement with the shell The usual ink-img i() is earried loy the inner end of the pen point carrying Section 8 and is disposed within the shell 3 to substantially fili the same.

The customary compressingbar 11 for the ink-ba is disposed within the shell 3 at one side ot the bag longitudinally thereof and is provided intermediate. its ends with the outwardly projecting rontrol member 152, which, in thepresent instance, is of segmental form and projects out through

regis tering slots

13 and 14 in the. respective inner and outer shells of the barrel. The slot 14 in the outer shell sections 1 and if; extends at both sides of the line of division between such sections so that when the member 12 is projected therethrough. it prevents a rela.- tive turning of the sermons 1 and 2 and ronsequently prevents a removal o the section 2 from the shell El. The comircssing-bar 11 and control member 12 are held in retracted or outwardlj,v :.lisposed position relative to the ink-bag, in the present instance, by a lock-ringr `lo ol' the eccentric split ring type, as in fountain pens of the` Conklin type, and this ring may be stamped from sheet metal or formed in any other suitable manner. projects through the control member l2 and when the split portion of the 'ing is in register with said member, the member may be compressed. The ring l5. in the` present instance, turns within a seat or a vguide groove provided in the :uli-arent cnil portions ot' the sections l and 2 b v the annular ribs or raised portions lo on said ser-- tions. lt will. be understood that the form of locking means and compressingbar rontrol disclosed is merel)l illustrative ot the idea and is not intended to limit the invention herein covered to the use of any particular form of compressirig-bar control or locking means.

As stated above, the rontrol member l2 of the compressitig-bar 11 is intended. when in its normal or outwardly projevted position` to perform the additional function of locking the inner shell sei-tion Il. together with the rear outer sei-tion l. when attached thereto. and the removable outer shell sern tion il. in assembled position by reason of the member l: passing through the slot 13 of the shell 3 and through the slot or notch t4 in the section 2, thereby locking the

members

2 and 3 against relative turning movements and preventingl a consequent unserewing of the Section 2 from the shell 2l. Such unscrewingir or removal of the sertion 2 from the shell 3 may be accomplislual. however. when the compressing-bar 1l and ,its-rontrol member 12 anl suliiciently depressed within the barrel to withdraw the member 12 from within the slot or notch ll4 of the section 2. It is therefore evident, lso far as the barrel section lockingr feature of the member 12 is concerned` that it mav be of any other form, suitabl i'or the purpose, than that illustrated7 as am' outwardly projecting part or control member for the har 1l might accomplish the same purpose.

It is evident that the ring 5' The form of the invention illustrated in Fig. il differs from that illustrated in Fig. lA in that. the outer shell., which is designated 20, is formed in a single section instead of two sections, and the inner shell il is '..ree For longitudinal and turning movements within the entire-outer shell. ln this form the outer shell il is uuscrewed outwardly from the inner shell 23 or away from the pen carrying section 8, thus necessitating a positioning of the threads 7 for such purpose.

lt '1s evident that l have provided a simple Aind cheap construction of pen barrel, which may be of metal or other suitable material; that the sections of the barrel may he quickly assembled; and that the sections oi.' the barrel are locked in assembled relation by the control member of the ink-bag ,fomprcssiiig-bar. and may be released by a movement ot' suvh control member from its normal position.

It is also evident that il'v it is desired to make a gold finished barrel, the outer shell may be composed of thin. rolled gold or plated, as desired, the inner shell being of suliirient strength and rigidity to reinforce the outer shell against compressing, twisting or bending stresses.

l wish it um'lerstood that my invention is not limited to any speciic'consti-action, arrangement or form of the parts, as it is capa ble olV numerous modifications and changes without. departing;` from vthe spirit of the in vention as defined in the claims.

Having thus described my invention, what l claim as new and desire to secure-hy Letters Patent., is,--
