WRITING DEVICE.

Aippl-icationled- July 23,1923, Serial No. 653;339.

Y To all .tc/Loin t may concern.'

-a eitizenot the AUnited I vented vcert-ain new Be it known that ALEXANDER CHESNE, States, residing at illinois, have iny and 4useful Improvements in VVritingDevices, of which the following is a specification.

Details of the present improvements relateto pencil construction and other details relate to. the construction of fountain pens. As a combined` utility the improvements 'relate to a pen-and-pencil organization.

The chief object otl the improvement is to for Writing with pencil or pen, and thus avoid the necessityv of tivo instruments'or devices. lt is an object to provide'a form of construction Chicago, Cook County,

whereby the chief advantages of such an organization may be had according to easily operable and conveniently used means.

In the accompanying drawings, `which form a part kof this speci-ication, Figure l is a medial longitudinal section through the device; Figs.

2, 3, 4 and' 5 are enlarged transverse sections on the lines 2--2, 3-3, tt and v5 5 respectively of Fig. l; and Fig. 6 is a medial longitudinal section through a front cap adapted for use With the instrumen-t for enclosing exposed pen and' pencil elements. v f t 'l 'The illustrated structure comprises rst a tubular body member or barrel l0 having an end fWall ll and having rigidly secured thereto atits front end a head member l2 which is shown Vas being threaded at 13 to engage the threaded portion 14 ofthe front cap l5.V cap tits with a. sliding and rotative tit upon the cylindricalbody l0.

The parts l() to 17 inclusive may Well be formed of hard rubber according to ordi n-aryfountaiI-i pen practice.

A metallic tube is threaded at A21 in fa cylindrical member 22 rigidly' secured within the Ahead 1nen1l. er "l2, the member 22 call the head and having jeetlon 3 constituting a feeder lor the 24,1vli1ch pen 24; 1S heldxln a 'recess in forming with the member l2 what ll shall an integral propen member 22, A channel'25 is cut in the `member 22 and a. hole or boring26 extends from the channel V to the ink chamber 27. This chamber 27 -is formed by a compressib'le soft rubber sack` which has an outer annular `Wall 28, an inner annular ivallA 29, and an end Wall as well shown in Fig. it.

`30, the Vchamber 2T thus being annular in the Renewed December 1, 1924.

shape, and closed at one end. The inner Wall 29 encompasses the tube 20 and is secured at 30, as by cement, upon a cylindri'cal extension 3l, part of the head piece l2, the outer wall 28 being similarly secured at 32 upon a cylindrical extension 33. of the member l2.

A `pair ot' spriugy sacit-compressing members 33, ot thin and stift sheet metal and formed trough-shaped where they overlie the inl: sach' are rigidly secured at Bit to the head l2, the rear ends being tapered or slanted inward as Well shown in Fig. l and adaptedy to be engaged by the ends of a IJ- shaped metallic member 3G slidably mounted for longitudinal movement in the end Wall ll ot7 the body member l() and also on the tube 20. ldlhen this member 36 is forced inward the saclecompressing members are forced toward each other, thus compressing the sack, exhausting air therefrom, and providing tor an intake ot ink into the sack when' the pen part is inserted in an inl; supply and the hand-operable member 36 is retracted.

The tube 2O carries a collar 1S held by screws 19 toV the end Wall 1l. lithin the tube 20 is a tube 37 interiorly screw threaded throughout most of its length `and adapted to be engaged by the screw-threaded crosshead or traveling member 3.8 to Which is secured a push rod or plunger 39 which passes `into the hollow pencil tip 4() and is adapted motion-'trom the cap 21T to the lube The springs 4.5 hold thc cap 17 readily rcleusably upon the tube ft2, and the cap li' may be pulled olli' o'l the end ot the barrel l0 whereby 'access' may bc had to the sack-.filling member Then the cap 17 is in its operative positlon as shown by Fig. l and the cap is turned in one direction or the other the tube 42 will be turned, and since this tube is slotted to accommodate the cross head 38 so as to move longitudinally therein the rotative motion will be communicated to the cross head which is thus made to travel upon t l) l) Vse i ce

r40 back into the body ot the device to the threads of the tube 37, with the result that the plunger' 39 is advanced or retracted.

rI`he view ot Fig. 1 shows the device as adjusted for using the pencil. Should it be desired to use the pen 24 the pencil tip 40 is retracted by simply pulling upon the cap 17, the holding effect of the springs 45 in the reduced or neck-like seat at 44 ot the tube 42 providing that this inner tube 42 will move longitudinally when the cap 17 is so moved. he pencil tip 40 isscrewthreaded at 47 into the tube 37. 'llo communicate pulling strains from the inner tube 42 to the tube 37 these two tubes are caused to move `simultaneously by a pair ot diametrically-opposed threaded pins 49 which are threaded through the wall of the tube 37 and into an annular recess in a collar 53 (Fig. 3) secured upon the inner tube 42. The inner tube 42 may thus rotate relative to the tube A37, Vand pulling and pushing strains upon the inner tube 42 will be communicated to the tube 37 and the pencil tip 40 will thereby be moved backward or forward as the case may be. To permit longitudinal movement of the tubes 42 and 37 the outer tube 20 is slotted at 55.

WhenV it is desired to move the pencilftip ree the pen 24 tor use the cap 17 is drawn back longitudinally. When the pins 49v come to the end of the slot55 aV further pull upon the cap 17 will release itat the spring connection at 44 and 45 and thereupon the U- s'haped member 36 may be forced inward by the ngers of the operator, partially collapsing the ink sack, and on inserting the pen point into a vsupply of ink and retracting the member 36 the spring members 33 will move away from each other, allowing the saclr to expand to its vnormal condition, drawing in the ink, Vand thereupon the cap 17 may be replaced.

Y The cap of Fig. 6 may be applied when the pencil tip 40 is retracted, the construetion being such that the central extension 58 of the cap having a recess 59 for the lead will act as a seal to prevent leakage of ink fromV coming objectionably upon the end of the pencil ltip and lead. Y
