serial Nt. 290,530.' Divided and this application sied 1tay7,19o7.v saisi No. 372,363.
.With these various objects of this invention in view,
the said invention consists, primarily, in the novel` fountain-pen; and, furthermore, this invention consistsl To alli'whom it may concern:
Be it known that I, WILLIAM C. LUTHER, a citizen of the United States, residing at Newark, in the county New Jersey, have invented certain new and useful Improvements in Fountain-Pens; and l dohereby declare the following to be a full, clear, of the invention, such as will an essential part of this specification.
The invention is clearly illustrated in the accompanying drawings, in which r- `Figure l is a plan View of a fountain-pen embodying pen-holder being represented in longitudinal section, said view showing the suction-device in side elevation, within the closed holder, when filled with ink, and is ready forense in writing.' Fig. 3 is a similar view of the same parts, showing theA telescopically arranged parts of the suction-device in their is composed of a transparent or translucent material, so that the ink contained within the holder is always exposed to view, and the user gf the "pen can readily see when the reservoir or pen has to be refilled with a fresh supply of ink. i
A further object of this invention is to provide a novel andisimply constructed is movably connected with and fresh supply of ink into the holder.r Fig. 5 is a longitudinal section taken on line 5-5 in Fig. 2, onan enlarged scale, of the upper end-portion of the pen-holder, and of the closed members of the suction device, the plunger, however, being shown in elevation; 6 is a transverse section of being taken on line 6-6in are views similar to Figs. 4 and 2, respectively, showing ithe fountain-pen provided with a suction device of a modified construction, but still embodying the principles of this invention.
Similar characters of of the said above descr sponding parts.
constructions of fountain pens.
The object of following up the supplyfof ink, as it is being used up, Vby the plunger is, as has been stated, to the ink, and thus avoid the ink being forced by such collection of the reference are employed in all 'bed views, to indicate correi the reference-character l indicates a hollow or tubular holder or barrel, which is parent material, such as glass, Celluloid, orathe like, but which may be the usual hard rubber barrel, if
A further robject is that it can be used 1n the manner of-a syringe for suckbarrel 1 is provided with the usual construction of inkfeedingmember or sleeve 2 carrying the usual nib or pen 3, the said s`leevev2 being detachably connected device by contact with the inner surface of the reservoir with/the said end-of the holder or barrel in'any usual the ink from said surface, and well-known manner. At its opposite end the said that a clean reservoirfor a fresh supply of ink will bel holder or barrel' l is made with a reduced and shoulf the result. )dered end-portion 4 upon which is slipped and held Other objects of this invention not at this time more by frictional contact, a second member or sleeve' 5, the particularly enumerated will be clearly .l understood outer end of the said sleeve 5 being closed by means of followingdetailed descriptionof theinvention. a removable plug or cap, of substantially the conthe pen-holder has been Referring now to the several figures of the drawings, M
preferablymade from a transi desired. At its forward end the said tubular holder or los j struction shown in the several iigures 0i the drawings. While I'Epreier to havethe said holder or barrel 1 oi a transparent material, or the purposes hereinafter more fully specified, I preier to make the sleeves or members 2 and 5 oi ar non-transparent material, preierably oi vulcanizedb orv hard rubber` whereby the general appearance oY the ountain pen is greatly enhanced. The said plug or cap 6 is preferably provided-with a reduced and shouldered end-portion 7 by means oi which the said plug or cap is held in irictional, but removable engagement with the outer end-portion of the sleeve 5. While the said sleeve 5 is held in irictional engagement with the reduced and shouldered end-portion 4 oi the holder or barrel 1, the said sleeve 5 may also be rotatedfupon said end-portion 4 ior the purpose to be presently described.
Coming now to the construction lof the suction-device vfor filling the said holder or barrel with ink, the said barrel or holder is provided with an internally arranged i f v ings, it will be seen,`that these various sleeves can be ring 10, which is suitably secured in its fixed position within the end oi the holder or-barrel, preierably by means of pins 11, as shown, or in any other suitable means. The said suction device comprises a plunger 12, which may be oi rubber, cork, or any other flexible .materiah in slidable and rictional engagement with "the inner cylindrical surface oiisaid holder or barrel 1,
' elongated slots or openings pin 2O moving in said spiral said plunger 12 being disposed between a pair oi com pressor and re-iniorcing disks or plates 13 and 14, which are suitably arranged upon the end-portion oi a plunger-rod 15, and are suitably secured upon said rod and in their compressed relation'upon the opposite faces oi the plunger 12, by a nut 16 upon the screw-threaded end, (not shown) oi the said plunger-rod 15. The said ring 10 acts as a stop, againstwhich the disk or plate 13 is brought in Contact, to prevent the withdrawal or the plunger 12 irom the holder or barrel, when the telescopically arranged parts o the suction device are drawn out or extended for operation, in the manner and for the purposes now to be more particularly set iorth. Encircling the said plunger-rod 15 is a sleeve 17, which is made with a pair oi oppositely located spirally formed 18, extending from a point near one end of the seeve 17 to a point near the other end oi the said sleeve, the said spirally formed slots or yopenings 18, being ,made in the same' manner as a double-threaded screw. The said rod 15 is provided at its free end 19 with a laterally extending pin 20, having its ends projecting from the opposite sides of the said rod, and respectively extending into the oppositely located slots or openings 18 of the sleeve 17. In this manner the said sleeve 17 is both slidably and rotatably arranged upon the plunger-rod, the end-portions of said brought in engagement with the recessed end portions 21 oi said slots or openings 18. Encircling -the said sleeve 17 is a second sleeve 22 which is made with a pair oi oppositely located spirally formed elongated slots or openings 23, which extend from a point near one end oi the sleeve 22v to a point near the other end oi the sleeve, the said sleeve 17 beingprovided at its free end 24 with a laterally extending pin 25, having its ends projecting from the opposite sides o said sleeve 17 ,and respectively extending into the oppositely located slots or openings 23 of the sleeve 22. Thus, the said sleeve 22 is both slidably and rotatably arranged upon the sleeve 17 the ranged openings or slots, until end-portions oi the pin 25 moving in said spiral openings or slots 23 until 22, may be employed, said sleeve being made with alpair. o oppositely located spirally formed elongated slots or openings 28, which extend irom a point near one ond of the sleeve 27 to a point near the opposite ond oi the sleeve, the said 'sleeve 22 being provided at its irce end 29 with a laterally extending pin 30, having its ends projecting from the opposite sides of said sleeve 22,` and respectively extending into the oppositely located slots or openings 28 of the sleeve 27. In this manner, the said sleeve 27 is both slidably and rotatably arranged upon the sleeve 22, the end-portions oi the pin 30 moving in said spiral openings or slots 28 until brought in engage-` ment with the recessed end-portions 31`o said slots or openings 28.
`From an inspection oi the several figures oi the drawclosed up, in the manner oi the sections oi a telescope, upon the said plunger-rod 15, so as to be directly within the sleeve 5, and out oisight, when not in use, as indicated in Figs. 2 and`5. That the said telescopically arsleeves may be drawn out into their extended relation shown in Fig. 3 oi the drawings, the said sleeve 27, as will be seen more particularly from an inspection oi Fig. 5, has arranged and suitably secured within its ree end-portion 32, a disk or plate 34 which is provided with a stud or stem 33, extending into and loosely arranged in a tubular portion 35 of the previously mentioned cap or plug 6. ,The said stud or stem 33 is provided with a screw-threaded socket 36 into which is screwed a screw 37, having its head 38 in retaining engagement with a washer 39 resting ina depression 40 in the face oi said cap or plug 6, substantially as shown. 1n this manner, the parts are operatively connected, and the said cap or plug 6 serves as a finger-piece or knob, or bringing the telescopically arranged sleeves and the plunger and its rod from the relation indicated in Fig. 2 to their extended positions shown in Fig. 3, until the various pins are brought'into holding engage# ment with the several recessed parts 21, 2,6 and 31 o the respective sleeves 17, 22 and 27. `The parts are now in position or moving the plunger l2 in a reciprocatory manner within the holder or barrel 1, as in a syringe or pump, from the position in said Fig. 3 t@ that represented in Fig. 4 oi the drawings. By dipping the nib or pen into the ink, and returning once more to their positions shown in said Fig. 3, the ink is readily sucked into the holder or barrel 1, the latter thereby becoming replenished with a complete supply oi ink. By means oi a slight twist, the various pins can again be removed from their retaining engagement with the recessed portions 21, 26 and 31 o the respective slots or openings 18, 23 and 280i the sleeves 17, 22 and 27 and by pressing the parts in the direction toward the opposite end oi the holder or barrel 1, the said parts of the suction device are again returned into their closed relation within the sleeve 5, with the cap or plug 6 once more closed down` upon the shown. l i.
Of course it will be understood, that although in the foregoing description and in the drawings I have dei scribed and illustrated an arrangement of three telebrought in engagement with the 'recessed end portions 26 oi the said slots or openings .23. Another sleeve 27, which encircles said sleeve the plunger and its parts, y
end oi said sleeve 5, as
req
seaeos scopically arranged sleeves 17, 22 and 27, the number of such sleeves and their arrangement may be departed from, and a smaller or larger number of such sleeves may be used, if desired. Instead of the spirally arranged slots or openings in the various sleeves, the said tubes or sleeves 17, 22 and 27 may be provided with the straight and longitudinally extending slots or openings 4l, 42 and 43, and the retaining off-sets or recessed parts 44, 45 and 46, respectively, and as clearly indicated in Figs. 7 and 8 oi the drawings, the actions of the several parts being the same as hereinabove described, in connection with the construction shown in said Figs. l to 6 inclusive, except that the sleeves instead of having a rotary motion in addition to the longitudinal motion, are capable only of a reciprocatory sliding motion longitudinally one upon the other. After the holder or barrel has been replenished with ink, and the parts of the suction device have been closed, in the manner shown in said Figs. 2, 5 and 7, the pen can be used for Writing.
