FOUNTAIN-*PEBL Specification of Letters Patent.

Patented Mar.3o,192o.

vApplication led March 21, 1919. Serial No. 284,202.

To all whom t may concern:

Be it known that I, HENRY J. JoRGENsEN, a citizen of the United States of America and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Fountain-Pens, of which the following is a specification.

This invention relates to fountain-pens of V of convenientb dimensions, and actually com- V pact in structure.

Another object is the production of a fountain-pen of the kind mentioned having no part that protrudes exteriorly thereof, when the pen is filled and in working condition, so that'a person carrying the same may not be troubled with the clearing of an obstruction every time it is put in or taken out of the pocket in the usual manner.

A further object is to provide a simple construction for a pen of the character described, comprising only a few parts that can be quickly assembled or disassembled, though not liable to get out of order, and shall not prevent the renovation nor hinder the renewal of any standard portion of the pen that may need to be repaired or changed from time to time.

Still another object is the provision of a pen of the nature specified that shall be eiiicient, easy to manipulate, strong, durable, adapted to be manufactured either plain or with any approved style of ornamentation, and yet amenable to lowcost of production.

Other objects and advantages of the invention will become apparent as the specification proceeds. y

With the aforesaid objects in view, the invention consists of the novel combinations and arrangements of parts hereinafter described in their preferredr embodiments, pointed out in the subjoined claims, and illustrated on the annexed drawing, wherein Vthe barrel.

like parts are designated by they same reference characters throughout Vthe `several views.

In the said drawings,- Figure I is a sectional plan of a fountain- `pen embodying a convenient form of the invention, certain parts appearing in full view, and others being omitted;

Fig. II is a sectional side elevation of the same embodiment of the invention, the actuating elements thereof being, shown in their open or operative position;

Fig. III is a similar-.elevation with the said elements in closed or in operative position, a part being left out;

Fig. IV is a transverse section, lookin in to `the pen toward the right-hand en theireof, as shown in lthe preceding views; an

Fig. V is an end view, showing the closed extremity of the fountain-pen, -lookin at the exterior thereof, that is, toward the Iefthand side of the drawing as related to the other figures.

Generally described, the improved form of writing .implement disclosed herein comprises, in combination with the customary parts of a self-filling fountain-pen, a de- Yunderlying the same, the collapsible inkcontainer thereto 4attached, and the barrel inclosing the latter. The defiator consists of a flexible tongue fulcrumed at one end upon a pivot-pin disposed transversely of the barrel head. It is stii'ened intermediately of its fulcrum and the point of flexure, and thence curves upwardly under the inkcontainer, to deflate it when needing to be re-charged. A bell-crank lever is provided to raise the deflator as required. This bellcrank constitutes a closure for an elongate opening made in the barrel head, and is so connected therewith that it swings in and out entirely within the projected area of The shorter arm of the bellcrank is the instrumentality employed to actuatethe deflator, and it is normally spaced from the latter when the barrel is closed, so that there occurs a preliminary movement or pre-travel of the arm prior'to 4 Y its contact with the deflator, thereby facilitatingthe opening of the closure and enablingV thebellcr'ank to 'be placed in the most favorable position to carry out the deflating operation. r Y n The advantages of the invention as here outlined are best realized when all' ofits" features and instrumentalities are combined in the one and same structure, but, usefull devices may be produced embodying less than the whole.

It will be obvious to those skilled in the '.art to which the invention appert-ains, upon 4emplified in the' drawing comprises, as usual, Aa penl point or niba, with a sublying feedbar .5, both of which are entered into the outerfend of a penlstockV c. The latter' has a shanl; d, fitted in theopen'end of a barrel e. A .neck f is formed on the shank, to receive the mouth of a deiatable sack g, adapted to hold the ink. Thence the sack extends inwardly into the barrel c, toward the. normally closed .end or head thereof, designated by the reference letter 7L. The several elements above enumerated are found inthe ordinary types of self-filling fountainpens, and therefore no claimis made to any one among them, save in so far as they may constitute .parts of legitimate combinations with the novel components of the present invention.

Transversely of the head '7L of the barrel c, .is .formed an elongated aperture 11, the upper edge whereof, as seen in Fig. II, 1s

shapedl sofasV to constitute .a rounded lrp12,

'of a belli-crank vlever as shown", is provided for the said aperture 11, The principal part ofthe closure 1s formed by the longer arm of this'lever, the shorter arm 17 where- ,of overlies the beveled edge 13 above' mentioned, the bevel, it will be observed, providing a clearance for the lever, when 1n closed position.. Fig. III.

The' bell-crank lever just referred to is .A pivotally mounted on a. pin 18, carried in Vthe head 72; of the barrel c, at right angles (SU to the aperture 11, previously mentioned. Figs. II, III, vand IV.

Between the outer extremity of thelong arm 1,6` ofthe bell-*crank constituting the closure aforesaid, and the adjoining wall of the barrel e, is provided a locking' device,

which may be in the natureof a resilient latch 19, formed a continuation of the safidar'm. This vlatch-is adapted to take nnder and effect engagement with the lip 12, when the former is pressed inward between the opposed sides of the aperture 11. Thus held by the latch, the bell-crank affordsV a full closure for the apertured head of the pen-barrel, as illustrated in Figs. III, IV and V.

In order to'v guide the said arm 16 in its inward movement, and also impart rigidity thereto, flanges'QO' are providedalongthe opposed lateraledges of the' sam-e. These flangesA may fill al'bproximately the angles intervening between the arms 1G and 17 of the bell-crank lever, at the oppesite sides thereof, respectively, c as clearly shown in Figs. II and III. Through and across the said flanges is passed the before mentioned pin 18, that pivotally supports the bellcrank.

Upon the -pin 18, intermediate ofthe flangesl 20, is also pivoted an eye 23, formed constitutes; a presser wherewith to deflate the. sack or container' g, preparatively Vvto filling" it with ink. The connection of'the tonguewitlr the pinl is independent of' that of thebell-crank, and suoli that when the latter is in closed position, the tongue lies above and spaced'away from the short arm 17; As a consequence, this arm hasa preliminary movement, mielusirelyk its own, to ],erfor'r'n before it can reacl'rthe underside of' tlie tongue, whenever the bell-cranhr is swung open.-L Upon toucliing-the tongue, it is understood, the arm 17 operates to raise the' same against the sack g, so as tofdeflat'e it preparatory to drfai vving inli-thereinto. The preliminary movement, or lwhat may be termed the^ pre-travel, of the arm 17, enables the arm 16, to wit,- that part of the bellcrank which constitutes the closure of this improved writing implement, to be swung out partly before any pressure'is applied to the tongue, incidental to Vsqueezing the sack g flat, to expel the air and produce a vacuunr therein.v The bell-cranlr lever, therefore, is placed in the b'est position to obtain an effective' purchase upon' the tongue before vtouching the latter', and no resistance is'coffered in drawing Vit ont, other than'that of the spring latch 19. Actually, the combinedbell-crank and closure can opened without effort by a slight pull with the thumbnail, Vand a further movement outward will bring the tonlgueiinto contact with the sack g, as may be seen by referring to Figs. 1I and'IIL i i I Thev tongue 24 is stifi'ened-4 so as to.l resist bending, close toit'sffulerum and at. a certain distance therefrom, before an' initial flexure takes place at the free end of the tongue. To this end, the tongue is provided with a reinforcement, which may be in the nature of a rib 25, Vpreferably formed integral therewith. Such a rib may be produced, for instance, by a depressionextend' ing along tle underside of the tongue for the major part thereof, and alsoin its upper face, as at 26, adjacent to the fulcrum or pivotal connection 23. See Figs. 'I to IV inclusive. Y Y

It will be noted that the Dell-crank lever hereinabove described is arranged to swing endwise of the pen-barrel e, that is, within the projected area of the writing implement. There is no obstruction or protuberance whatsoever located or occurring exteriorly ofthe cross-sectional area of the barrel, and nothing that extends outward longitudinally of the implement, when put into condition for actual use. There is but one aperture, slot, or recess provided in the barrel, and that occupies only a small space diametral to the end or head h, which is closed by a smooth-faced cover Vat all times, except when the pen has to be refilled. The closure is held sufficiently tight by means of the resilient latch or retainer 19, which may be an inward projection of the lever arm 16, as shown, or in any other suitable manner. The bell-crank may be loosely pivoted on the same pin as the tongue, as represented, or otherwise fulcrumed, if preferred. In either case, however, the tongue 24 should be jioating independently of the arm 17 of the bellcrank, to insure the pre-travel or separate Y specified.

initial movement hereinbefore The lever being flanged sidewise, it will be noted that it affords ample protection to the pivoted end of the tongue, to the extent at least that its connection with the pivotpin 1S is shielded laterally as well as rearwardly whenever the bell-crank is swung open, and besides the tongue is properly guided at the point of fiexure by the joint action of the flanges 20 and the free, upwardly-projecting end of the short lever arm 17. Thence the tongue assumes the curve represented in Fig. II, when flexed during the operation of replenishing the deflatable reservoir with ink, as before explained.

While a certain preferred embodiment of this device has been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made, without departing from the scope of the invention as defined by the appended claims.
