FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed December 23, 1914. -Serial No. 878,747.

of Jackson and State of Missouri, have in-' vented certain new and useful Improvements 1n FOUIlttlllbPfiIlS; and I do hereby .declare the following'to be a full, clear, and

exact description of the. invention, such as sirable that the lever be normally securely held so that no part thereof will project "from the slot in the fountain pen barrel in will enable others skilled in the 'art to whi lL.

' it appertains to make and use the same.

This inventionrelates to improvements in fountain pens,'an'd more particularly in socalled lever-filler or self-filling fountain pens. and has for its particular objectto provide a fountain pen of this character in which the lever for actuating a sack-c01 lapsing means is held firmly but yieldinglx in open and closed positions respectively, by means other than and acting entirely 111- dependent ot'the said sack-collapsing means;

The invention consists in the features of construction and combination of parts here:

inat'ter fullv deswihed and partieularl claimed. 1 in" the accompanying drawings illustrating the invention: Figure l is a" fraguieutarv central longitudinal section through the barrel of a fountain 'pen equipped with a collapsible ink-sack and sack collapsing means including a lever for actuating the latter embodying m v invention. Fig; 2-

Figs. -5-- and are .views similar to Figs. l and respectively. illustrating a further modified term of construction. Fig. '-T is a view similar to Fig.

'iillustrating a difl'ereut method of securing thespring to the lever. Fig. is a view similar to Fig. l shi'iwing a 'urther modification in construction; Fig. 9 is a fragmentary section on the line of Fig. 8. Fig. -1() is a fragmentary detail plan view of the slotted portion of the barrel of a fountain pen showing the lever and a member associated therewith illustrated in Figs. S and '9. Fig. -l1 is a perspective view of the lever shown in Fig. 9.

In lever filler fountain pens it is very ties which said lever is pivotally mounted, whereby the accidental catching of the lever in the lining of the pocket of the user and the consequent operation...of....said lever in withdrawing the pen from the'pocket, where by the ink sack would be collapsed and the ink ejected, is obviated. It is also desirable, though of less importance, that the lever be firmly supported in its open position to maintain the sack collapsed after the lever has been turned to this position, and until the inlet or nib end of the fountain pen has been inserted in an ink-well preparatory to permitting the same to slowly expand to draw in a supply of ink. It will be obvious. of course. that the lever ma v be digitalb readil v held'i'n the last-named position without inconvenience, and that it is not very essential to 'provide'nieans for maintaining the lever in this position, for the reason that. an

aei' idental closure of the lever would not re sult n any disaster such-as would occur by the e ection oi ink in the'pocket of the clothing by an accidental opening .i'novement of the lever in withdrawing the same from the pocket.

further object of the invention is to provide means whereb the closing movement of the lever is resisted tOiH'PlCOllIG the tendency of the sack-collapsing means to turn the same to closed position, it being desirable to permit the sack to expand slowly b v Illtltlllilll) releasing the collapsing pressure thereon as it has'been found that; when the operator releases the sack-collapsing means suddenly from engagement with the sack hedoes not allow for'the slow expansion of the sack and removes the nib end from the ink-well before the sack has filled.

In the aeeompanving drawings illustrating the invention I have shown a fragnientar} longitudinal section of a fountain pen barrel 1 in which is housed the ink sack 2 ,and the sacleeollapsing means comprising the bar 3 and a spring carrier 4 for said bar. These elements constitute no part of the present invention and are. therefore, not illustrated in detail herein. the same being .more full illustrated in the patent to Kaufman, o. 827,022. dated the 24th day of July. 1906, and in the pending application of Joseph A. Kratcer. Serial No. 821393,

filed February 27,1914, and in the application of Harvey G. Craig, Scrialll'o. filed February 27, 1914-. The said bar 3 is adapted to be forced against the ink-sack 2 to collapse the latter against the resistance offered by the elasticity of said sack and against the action of the spring l supporting said bar within the barrel, by means of the lever 55, which is pivotally mounted'between its ends in a longitudinalslot 6 in the barrel 1 of the pen between the ends of said slot.

contiguous to one end of the slot and con tacts with the bottom of said recess the latter constituting a stop'for liiniting.the.

movement of the lever in-qone direction. The said lever is provided at its other end portionon opposite sides with flanges 9 which extend from the opposite'end of the lever to a point contiguous to the pivot 10 thereof. The last-na1ned ends 11 of said flanges are adapted to engage the inner wall of the barrel 1 on either side of'said slot 6 to limit the movement of the lever in the other direction, the total movement of said lever being substantially through an arc of ninety degrees. l l hen the pro gectlon 7 corn which extends substantiallyto the ends 11 of said flanges 9, or to a point contiguous to the pivot 10 ofsaid lever and normally lies upon the inner i a-c-e of said lever over the entire length of said spring.

In" the instance illustrated said spring 12 is secured to the lever by means of the rivets 13, but obviously the same may be otherwise so cured without departing from the inven' tion. v

s panning the slot 6 contiguousto the pivot and between the same and the secured end .ot the. spring 152. is a pin 'ltagainst' which thcfiiree end portion of the spring l2bears ct'with the bottom of the recess 8 and like-- wise to hold the flanges tl in contact longi tudinallywith the inner :Wall of the barrel on either side of said slot 6. lhe said pin serves to normally maintain the springdil, slightly separated at its-inner end from the face of the lever, or in other words, out of its normal position, thus causing the secure end or the springto draw the contiguou end of the lever into the slot to hold the said projection 7 in contact with the bottom The said lever 5 is oi": greater length. than said slot and is provlded atone end" with a pro ection 'l' engaged in a recess8 eldingly hold the projection 7 in con masses of said recess 8. It will be obvious, of

. course, that the said stop consisting of the bottom of said recess 8 may be omitted as the flanges 9 Wlll atlord a sullicient stop to hunt the inward movement of the leverand vice versa, the said flanges 9 may be omitted as a stop for limiting the inward movement of the lever and only the stop formed by the bottom of the recess 8 may be used. ior

that purpose. The said spring 12 will re sist movement of the lever to open position til the said lever has been turned through .n-a-rc greater than the angle formed between a line intersecting the axis of its pivot andlthe axis of said pin 14: and a line -perpendicular to the axis of-the barrel 1 flntersecting the axis of sand pivot 14:, and thereafter said spring will act to auto niatically turn said lever to-the open position indicated in dotted lines in Fig. 1.

In turning the lever to closed position the spring will similarly resist ithe movement thereof until said lever has turned through an arc equaling its total movement less the angle previously referred to, and there after it will automatically return the lever to its closed position. The said spring acts in conjunction with the pivot pin and thepin it similarly to the spring or apoche't knife and is ordinarily termed a jaclnilanife spring. The spring may be of any suitable form in cross-section, and may secured in any suitable manner to the lever. The same may also he applied to a lever devoid of the flanges 9 or similar stopi 'or limiting the opening movement of the lever, and as shown in Figs. 3.and -'l:- the inner end of the spring may be "provided with a; flange 15 which engages the pin 14 as the lever attains its open position and serves as a. stop for limiting "further. moveinentof said lever in that direct on. I

"llhe lever Bfillustrated in Figs. l '.andand the lever 16 illustrated in l and -lare shown as composed of a block of metal, but the samemay also be :"made of sheet metal as illustrated in detail nsFigs. -76- and -7 the body of the lever 16 there shown being U-shaped in cross section and the respective flanges thereof provided with outwardly extending flanges l8 corresponding to the flanges 9 illustrated in lugs. 1- and 2. As shown inFig.

6-, the spring'l'l' used may be secured to.

the lever by inserting the outer end of the spring between the flanges 19 of the body of the lever and pinching the same therein by contracting said enoLof said lever. The saidlflanges 19 of the lever may also, as illus trated in Fig. .'Z, be provided with pro ectio'ns 2G integral therewith between which the flat spring 21 is received and which will pend over upon the same to secure it to the ever.

The construction may be further modified as shown in Figs. 8- and -9 in which'there is mounted in the slot 6 1n the barrel 1 a member provided with a projection .23 extending from one end thereof midway between its side faces beyond the pivot 24: of the lever and into the slot 26 in the opposed'end of the latter and into engagement with the spring 27 carried by said lever :25. The said lever is provided at one side. of each of the arms bordering the slot 20 therein with a flange 28 corresponding to one of the flanges 9, shown in Figs. -1 and 2 or one of the flanges 18 shown in Figs. (3' and T. The invention may be further modified within the skill of the mechanic without departing, from the invention as defined in the appended claims.
