3 Claims. (Cl. 120-48) This invention relates to a fountain pen particularly adapted for use for drawing, writing and lettering.

The invention comprehends a fountain pen which provides convenient means for controlling and regulating the flow of any drawing or writing ink used with thepen.

Another object of the invention is to provide a pen having a needle for closing off the flow of the ink and with means adapted to be engaged by a tip of the finger of the user for moving the needle to open up and close off the fiow of the ink and for controlling the flow of the ink during use thereof.

Still another object of the invention is the provision of a slide member mounting the needle for reciprocatory movement toward and away from the ink discharge passageway and which slide member is disposed adjacent to the lower end of the pen in convenient position for manipulation thereof by the tip of one of the fingers holding the pen.

With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illustrated.

In the drawings:

Fig. 1 is a perspective view of a fountain pen in accordance with the invention.

Fig. 2 is an enlarged view in elevation showing the parts in separated juxta-position and a fragmentary portion of the handle in section.

Fig. 3 is an enlarged longitudinal vertical sectional view thereof with the handle omitted.

Fig. 4 is an enlarged transverse sectional view taken approximately on line 4-4 of Fig. 3.

Fig. 6 is an enlarged vertical sectional view taken approximately online 6-6 of Fig. 5.

Fig. 7 is an-enlarged transverse sectional view taken approximately on line 77 of Fig. 6.

Fig. 8 is a view in elevation of a modified form of fountain pen constructed in accordance with the invention and showing a fragmentary portion of the handle member in section.

Fig. 9 is an enlarged transverse sectional view taken approximately on line 9-9 of Fig. 8.

Referring to the drawings by character of reference, the pen may be of any desired character adapted to be conveniently held for drawing, writing and lettering and as illustrated in Figs. 1 to 4 inclusive of the drawings, a handle member '10 isprovidffed' to which an ink holder 11 is atfixed in prolongation of the lowerend thereof. The ink holder 11 consists of a cylindrical upper section 12 and a conical shaped lower section 13. The upper section 12 is formed with reduced upper and lower ends 14 and 15 which are exteriorly threaded for threadedly engaging the interiorly threaded ends 16 and 17 of the handle member 10 and the conical shaped lower section 13 respectively to secure the parts together.

The upper section 12 is formed with an opening 18 for I 2,878,783 Patented Mar. 24,- 1959 filling the pen with ink which is contained in the conical shaped portion 13. This portion terminates at its lower end in a reduced cylindrical extension 19 having a restricted passageway 20 for the flow of the ink. The lower end or tip 21 of the cylindrical extension 19 con-v stitutes a stylus for drawing, writing or lettering. Located within the ink holder 11 is a needle 22 having a blunt lower end 23 which is of a diameter slightlyv smaller than the flow passageway 20 to permit of the movement of the needle axially of the ink holder for engagement of the lower end thereof in the ink passageway as indicated in Fig. 3 of the drawings to close off the flow of ink from the pen. for axial reciprocatory movement longitudinally of the holder 11, the .upper end of the needle being somewhat larger in diameter than the lower end and fittingly engaging a bushing 24 in the reduced upper end 14 for guidely mounting the needle.

In order to permit of the convenient movement of the needle to control theflow of the ink during use of the pen and for closing ofi and opening up the fiow of the ink, a slide 25 is provided which is afi'ixed to the needle and protrudes through openings in the Wall of the upper section 12 in convenient location for engagement by one of the fingers of the hand grasping the pen. Thus when the pen is used, the slide 25 may be manipulated by the finger to move the needle 22 toward and away from the lower section 13 to control the flow of the ink. When the drawing, writing or lettering is completed, the slide is moved 'by the finger to close off the flow through the flow passageway 20.

The slide 25 consists of a rebent spring shown in plan in Fig. 4. The opposite legs are formed with inwardly

offset portions

26 and 27 which portions engage through

slots

28 and 29 in opposite sides of the needle 22. This retains the needle in fixed association with the slide. The slide protrudes through oppositely disposed

openings

30 and 31 in the upper section 12 above the feed opening 18. Either end of the slide 25 may be engaged by the finger for manipulating the needle 22.

The holder may be adjustably connected with the handle member in order to dispose the holder in any desired angular position with reference thereto as shown in Figs. 5 to 9 inclusive of the drawings. In this form of the invention the ink holder 35 consists of a cylindrical upper section 36 and a conical shaped lower section lower portion thereof. The conical shaped lower section 37 is formed with a cylindrical extension 45, the lower end or tip 46 thereof forms a stylus for making relatively wide lines. The conical shaped lower section 37 together with the cylindrical extension 45 are provided with a restricted passageway 47 for the flow of the ink.

Located within the ink holder 35 is a needle 48 similar to the needle 22 in the previous form of the invention. The needle 48 is formed with a blunt lower end '49 which is of a diameter slightly smaller than the flow passageway 47 to permit of the movement of the needle axially of the ink holder for engagement of the lower end thereof in the ink passageway to close ofi the flow of the ink. The needle is mounted for axial reciprocatory movement longitudinally of the holder 35 with the upper end thereof slidably protruding through a cap 50 which threadedly engages the upper end of the cylindrical upper The needle 22 is mounted- 3 section 36 to close the same: A slide 51 is provided whiehis-similarto theslide 25inthe previous-form ofthe invention and is formed with inwardly oifset portions 53 and 54 extending through slots 55 and 56 in opposite sides of the needle-48 for retaining the needle'in' fixed association with the slide. The slide protrudesthrough oppositely disposedopenings 58 and 59 in the cylindrical upper section 36 above the filling opening 43 with the opposite ends ofthe slide'in convenient position for engagement by-one of the fingers ofthehand holding the' penfor manipulation thereof toimpart reciprocatoryniorvernenttotheneedle.

In the? form of the invention: illustrated in Figs: 8'-

and 9 of-thedrawings', the ink holder 60- is-adaptedto' bTereleasably atfixed tothe handlemember 6-1 inplace of the pen point ofthe' usual type-'of writingpen. The ink holder 60 similarly consists of acylindrical upper section 62 and aconical shaped lower section 63'. The-upper section-62 is-preferably fashionedfrom: a strip of" thin sheet metal which is rolled into cylindrical formation with the'en'ds of'thestrip secured together in overlapping rela tion.

Tlieupper section 62,is formed with an upwardlyextendingtongue 64 which together with the-upper-end of said section, fits within the recessed lower, end of the handle member 61. The said section is also formed with an ink' feed opening 65- and with oppositely disposed slots 66 through which protrudes a slide 68 formanually moving a needle 69 for regulating the flow of the ink. The slide 68 consistsof a rebent'flat-springv which extendsthrough a slot 70 in the sideof theneedle 69 for retaining theneedle in fixed association with the;-

slide.

The conicalshaped lower section 63 constitutesthereceptacle for holding the ink" and is provided with a; cylindricallextension 74 having a passageway for the'flow of the ink similar to the flow passageways in the previous forms of the invention. The needle 69 is'mounted for guided'sliding movement in. aligned openings 71 in inwar'dly directed tongues 72 formed integrally with the" cylindrical upper section 62 and .bent" inwardly into overlapping relation.

It is to be understood that the slots in which the slide is slidable in each of'the forms of the invention are of sufficient length to permit of the movement of the needle so that the needle may be moved to dispose the lower end thereof in protruding relation from theink holder whenever the use;of the pen is discontinued and. when the pen is used again, theslide maybe moved upwardly to dispose the lower end of the needle sufliciently above the-flow passageway to permit of the flowof the ink therethrough. The slots are of'a width that'the slideifrictionally engages the opposite wallst'thereofso as'to'retain the; slide in any desired set position therein; '[he slides in the, several forms being positioned; adjacent-the lower: ends of" the handle members, respectively, as shown .in; Fi 1,,5f'and 8 of the drawings, are convenientlylocated" for: engagement by the tip of the' index'finger'of thehand" holding, the pen so that when the" pen is being .used, the
