WRITING INSTRUMENT.

Application led December 6, 1923. Serial No. 678,855.

To all whom t may cof/wem:

Be it known that I, MAURICE ALLAND, a citize-n of the United States, residing at At lantic City, in the county of Atlantic and. State of New Jersey, have invented certain new and useful Improvements in Writing Instruments, of which the following is a specification.

The object of this invention is to provide an improved writing instrument, compris ing the combination of a magazine pencil and a ppn of the cofcalled fountain type.

Anot er object is to provide such an instrument with a pencil-mark eraser carried by the pen portion of the instrument and with an ink-mark eraser carried by the pencil Iportion f the instrument.

Still another object is to provide a pencil portion of the instrument, means, connected with the piece of lead being used, which is adapted to co-operate with other means within the pencil casing, whereby the extent to which the lead projects from said casing is automatically (governed in accordance with predetermine detailshereinafter p set forth.

A further object is to provide such a pencil with an elongated cylindrical eraser, means for operatively supporting said eraser, and means for actuating sa1d supporting means, whereby when the exposed portion of the eraser is worn away the supportingl means permits the cylindriform member to be withdrawn further, and then clamped so as to prevent its accidental retreat into the pencil casing.

In those Vtypes of fountain pens which are filled by means of a dropper, or the like, after removal of the pen-point supporting head, it ma be possible to completely ill the reservoir, though this type is not only uncleanly but practically obsolete. However, niculty has been ,encountered in filling the reservoir to the same degree, when employing anyI of the various colla sible 'tube reservoirs in constructions less li ely to spill ink and soily the fingers when filling, as the action in this case depends upon the expulsion of air from the tube, and commercially feasible mechanisms for collapsing the tube apparently fail to expel all of. the air therefrom,

and resultingly draw in only a. portion ofk a full ink content. Y

A still further object is to provide a cylindrical reservoir having non-exible and preferably transparent side walls, a piston adapted to reciprocate therein throughout the entire longitudinal extent of said cylinder, and a rod extending slidably through that end of said cylinder opposite to the pen-supporting head, said rod being engageable with said piston by means of -an angular movement to reciprocate said piston to expel the air from the cylinder and then by a counter reciprocation to draw a full content of ink into said cylinder, after which another angular movement of the rod disenl gages the same from the piston, to permit the rod to be slid into the reservoir, to prevent interference with the convenient use of the pen.

And a still further object of the invention lies in the construction of the piston, that is providing a radially yielding member, secured between oppositely positioned heads,

which are preferably secured together, and

means to prevent movement of said member with respect to said heads; also improved means for connecting to and disconnecting said actuating rod from operative relation with respect to said piston; and also providing an abrasive ink eraser upon a cap member which normally surrounds and incloses the en when not in use.

Additiona objects and advantages of the present lnvention are fully brought out in the following description, when read in conjunction with the accompanying drawings, in which Fig. l is a longitudinal view of one embodiment of the invention, showing the pen portion in section; Fig. 2 is a similar view showing the pencil portion in section; Fig. 3 is an enlarged fragmentary view of a portion of the pen section of the device;

Fig. 4 is a similar view of another portion of the said pen section; Fig. 5 is a similar view of a portion of the pencil section of the device; Fig. 6 is a section on the line 6 6v of Fig. 2; Fig. 7 is a, section on the line 7-7 of Fig. 2; Fig. 8' is a section on the line 8 8 of Fig. 1; and Fig. 9 is a section on the line 9--9 of Fig. l.

Referring to the drawing, the pen portion of the instrument will first be considered. This portion comprises a hollow cylindrical member l, both internally and externally threaded at one end 2, the inner threads of which a're adapted to receive in normally watertight engagement, yet removable therefrom, thee annelled head 3 which operatively supports the pen-point 4. The opposite end of said member is closed by a transversely extending wall 5, provided in turn with a longitudinally extending reduced and an externally threaded portion 6, through which extends a central bore 7. Through said bore is adapted to reciprocate a rod 8, enlarged at its inner end 9, and threaded adjacent thereto for engagement with the threads of the central bore 10 of a cylindrical member 11, having a radial flange 12 at one end, provided with a spur 13, a cylindrical section of cork or other suitable material 14 surrounding the member 11, and being pressed against the flange 12 and prevented from rotation by the spur 13 as a result of a nut 15 lirmly engaging the opposite end portions of the outer threads of the member 11.

The rod 8 is furthermore provided at its outer end with a knob 16, by means of which the piston-head 12-14 is reciprocated within the member 1. l/Vhen the interior of said last-named member, that is, the reservoir portion of the pen, is filled with a writing liuid, the parts are in the position shown in Fig. 1, and the knob 16 is covered by a ferrule 17 engaging the threads of the extension 6, said ferrule also being provided with a pencil-erasing member 18 for use as hereinafter described. When the reservoir becomes empty, and it is desired to lill the same, the rod 8 is withdrawn and then rotated until the threads upon the inner end thereof engage the threads of the bore 1() of the member 11, whereupon the air is expelled from the reservoir by moving the said piston into its innermost position, thereby immersing the pen and supportinghead 3 beneath the surface of a writing iuid, and removing said piston to its outermost position as illustrated, the fluid is drawn past the pen and through the channel of the head 3 into the said reservoir. The rod 8 is then rotated until its inner threaded portion is disengaged from said piston, whereupon the rod is returned to its innermost fposition as illustrated, and the ferrule an eraser are replaced as shown in Fig. 1.

A c lindrical member 19 is provided, the same aving a centrally positioned recess 20, into which the pen 4 extends (as shown in Fig. 2) when the pen portion of the instrument is not in use, and in which position the parts are retained by the threaded portion 2 of the pen engaging the threads 21 of the cylinder 19. The member 19 ma be provided with a sprin -clip or thelike 22 for engagement with t e pocket to prevent the instrument from accidentally becoming lost, and is alsoprovided upon its opposite'end with the reduced threaded portion 23, upon which is normally secured the removable cylindrical member 24, which is Lesoagecs hollowed to provide a spare lead magazine 25 surrounding the tubular member 26, which is secured in spaced relation with the walls of said magazine by means of a collar 27. When the member 24 is screwed upon the head 23, said tubular member surrounds a smaller tubular member 28, which at its inner end is secured to and within the said head 23, and is adapted to contain one or more leads, depending upon their length, in addition to the lead 29, which is shown in Fig. 2 as in its normal position for writing.

The lead 29 is closely surrounded bythe inwardly extending fingers 30, made radially yielding by longitudinally saw-cutting the otherwise outer free end portion of the tubular member 26, which portion is also externally screw-threaded to receive thereupon a tapering head 31, which when screwed into the position shown in Figs. 1 and 2 engages and contracts the :lingers 30 upon the outer surface of the lead 29, to prevent its accidental recession into the tube 28. The member 31 is also provided with a sharply serrated portion 32, which is sutlicientl abrasive to make possible the erasure of lines or spots by carefully manipulating it.

The bore otthe tube 26 terminates outwardly in shoulders 33, forming a portion of the lingers 30, which .shoulders are opL posed in the opposite direction by the tree end portion 34 ofthe tube 28, but which opposed shoulders are separated to provide a reciprocat-ion between them of a sleeve 35, surrounding and in frictional engagement with the lead 29, which is exposed for use in writing purposes. Except when the tube 28 is filled, the lead 29 when not in use may be returned to an inner protected position as shown in Fig. 1) by loosening the member 31, and merely pushing the lead inwardly until the sleeve 35 abuts a ainst the shoulder 34, whereupon the mem er 31 is tightened into operative position, and by means of the contracted fingers 30 prevents the lead from slipping into itsextended position. If the sleeve 35 engages the shoulder 34 before-the lead is com by the head 32 of the mem er 31,"while the lead is loosened, the movement of the lead 29 is continued inwardly, while the sleeve slides thereupon until suchI inward movements ceases. Thereupon, when it is desired to expose a predetermined len h of lead for use, the member 31 is loosene and the lead 29 permitted to slide therethrough y by gravity, which movement will continue unti the sleeve 35 co-operates with the shoulders 35, after which the member 31 is tightened and the encil portion of the instrument is ready or use.

1t will then be seen that with the pen shown in Fig. v1 inverted into the in erative position shown in Fig. 2, the pencilletely hidden lao Having thus described my invention, what I claim and desire to protect by Let.
