ILLUMINATED FQUNTAIN PEN.

Application filed March 20, 1824.

To all whom it may concern:

Be it known that 1, JOHN J. DEVINE, a citizen of the United States, residing at Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in illuminated Fountain Pens, of which the following is a specification.

This invention relates to a fountain pen, of the illuminable type, and has for its object to provide a pen of such class, in a manner as hereinafter set forth, with automatically shiftable means to provide for the illumination of a writing surface at and surrounding the writing point when using the pen.

A further object of the invention, is to provide a pen of such class, in a manner hereinafter set forth, with a lamp for illuminating the writing surface and to so position the lamp within the pen body to provide for an increase in size of the ink reservoir, whereby the ink carrying capacity of the reservoir will be materially greater than the capacity of the reservoirs used in fountain pens of the same class.

A. further object of the invention is to pro vide a pen of the class referred to, in a manner as hereinafter set forth, with new and novel means whereby the lamp, the socket therefor, and the holder for the lamp and socket can be quickly and conveniently inserted and removed from the pen body when occasion requires, and further to prevent said holder from accidently sliding out of posi tion from within the pen body.

A further ohiect of the invention is to provide a pen of the class referred to, in a man ner as hereinafter set forth, with means for utilizing a flat battery for the lamp. whereby a pen body can be set up of reduced length, with respect to a pen of the class referred to employing a battery of tubular shape.

A further object of the invention is to provide a pen of the class referred to, in a manner as hereinafter set forth, with a removable soft rubber ink reservoir capable of being self filled, and further capable of being Serial No. 708,595.

quickly positioned within and removed from the pen body and by such provision a reser voir of simple construction is employed resulting in expeditious manufacture of the reservoir and the quick setting up of the fountain pen.

A further object of the invention is to provide, in a manner as hereinafter referred to, a pen of such class, with means whereby the ink does not come in contact with any metal part of the pen body when the pen is employed or not in use.

Further objects of the invention are to pic vide, in a manner as hereinafter set forth, a fountain pen of the illuminable type, which comparatively simple in its construction and arrangement, strong, durable, compact, thoroughly efficient and convenient in its use, readily assembled, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and. illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

Referring to the drawings in detail. 2 fountain pen, in accordance with this invention, comprises a pen body formed of a hollow polygonal shaped section 1 and a hollow cylindrical section 2 formed at one end with a polygonal shaped 'Gfil'tnflrd'l 3* which is vertically disposed and torlned with a flange 4t inset with respect to the edges of the extensimi whereb; a shoulder 5 is formed. The flange 4- has a series ot openings 6 for the reception of logs 7 carried by the section 1 whereby the latter and the section 2 are detachahly connected to gether.

The section 1 provides a hatter cl'nnnher T which is oi greater length than the length of the battery 8 encased lay the section 1. The battery 8 is of the same shape as the shape of the section 1 and when the pen is view oi the in position to be used the battery 9 slices towards that end ol the section 1 whirh is connected to the flange 4-.

hen the section 1 is mounted in po ition. with respect to the section the section 1 is seated upon the flane'c 4: and abuts against the shoulder and the hats T extend into the openings 6 whereby the sect as are detachably connected together. The section 1 is narrow so that the battery 5% nanrnml there-in will be flat and by setting up the section 1 to receive a fiat battery; the lereth thereof can be inateri l reduced. which would not be the if a tubular ba trv was employed.

The section 2 is of substantial 1 length and diameter and projects iroin the lower part of the extension 5-3 and the \lian'ieter oi the section 2 is substantiall equal to the width of the extension 3. The cylindrical portion of the section 2 is inte; al with the extension and said cylindrical portion provides a sleeve which has the part thereof in proximity to the extension 8 threaded as at 9.

The extension 3 is formed with an opening which registers with the cylindrical part of the section 2 and the said opening is indicated at 10, and above the opening 10. in proximity to the upper end of the er-ztension 3 the latter is provided with an opening 1.1 and an upwardly inclined interiorlv threaded sleeve 12 which registers with the opening 11 and the function of the 12 will be presently referred to.

jlxtending across the opening 11 an! arranged against the inner :tace oi the extension 3, is a contact member 13. secured in position by the holdttast devices 11-. The opening 10 in the extension 3 establishes communication between the cylindrical par of the section. 2 and the battery chamber T The liiattery 8 is provided with a terminal 15 which cooperates with the contact 1 and said battery 8 is furthermore provided with a substantially elongated terminal H? e):- tending to the opening 1.0 tor the purpo e to be presently referred to.

Threadably connected to and arranged within the section 2 ol the pen body is an inner shell of substantial length and diznneter and which is formed of an internnaliaw portion 1?, an inner end portion in. and a forward end portion 19. The end portion 18 is threaded for engagement with the threaded inner portion 9 of the section 2 of the pen body whereh the inner shell is detachably connected to the sect on :2. The end portion 19 is ol tapering contour and has the sides thereof rut imvardlv in r. semi-circular manner as at 20.

The interi'nediate portion 17 between its center and the end portion lfl is formed with a circular opening 21 and at a poin between its center and the rnd portion i is slitted as at 22. and the material t e-A by the slit is bent to extend inwar l v oi the portion 17 to torrn a semi-circular slop lug L The intermediate portion 17. directly below the opening 2! is torna-d with arectangular opening 2t which rcnnnnnicates at its rear with a longitndinallv ewtending rectangulm' slot 25. The inter mediate portion 17. has its bottom sl ttrd s at 26, 27. and the n'iaterial trend by the slits 26 and 27 is bent inweidl to torni a pair of oppositely disposed ion "tadinalh' extending supporting flanges 28. :3

Disposed axially oil the inner shell, as well as projecting forwardly therefrom. and of a length to terminate in proximity to the forwa rd end of the intermediate portion 17. of said inner shell, is a metallic sleeve 30. having formed integ'al therewith series of radially disposed arms 31 which are connected to the inner faces of the portions 17 and 19 of the inner shell. Extending through the sleeve 30, as well as being secured therewith by the rivet 32, is a hard rubber tube 33 having projecting from its ltlii llt) lfl

outer end the pen point 34 and feeder 35. The rear end of the tube 33 has projecting therefrom a curved extension 36, which extends into and is secured with a hollow soft rubber body 37, which provides the ink reservoir 38 and said extension 36 communicates with the reservoir 38 for conducting the ink to the feeder 35, for the purpose of supplying the ink to the pen point 34. The soft rubber receptacle 37 is arranged forwardly of the lug 23 and is also mounted upon a lamp socket holder to be presently referred to. As shown in Figure 6 the soft rubber receptacle 37 snugly engages the inner face of the inner shell. The curved 8X- tension 36 communicates with the upper portion of the receptacle 37 as shown in Figures 2 and 6.

The opening 21, in the intermediate portion 17, of the inner shell, provides means when the inner shell is removed, whereby the receptacle 37 can be compressed for the purpose of self filling, in connection with the opening 24. The filling of the reservoir 38 can be had without detaching it from the tube 33 or detaching the latter from the sleeve 30.

The receptacle 37 is formed with a neck 39 and to this neck is secured the curved extension 36, and with the neck arranged at the upper portion of the receptacle 37. Arranged below the neck 39 is a lamp 40 provided with a plug 41. Associated with the plug 41 for the purpose of positioning the lamp within the inner shell is a holder formed of a hollow body portion 42 providing a socket of substantial length having its wa l threaded as at and extend ing into the body portion 42 and engaging with the threads 43 is the plug 41. In longitudinal section the body portion 42 gradually decreases in height rearwardly and the socket formed thereby therein also extends at an inclination whereby the plug 41 will be disposed at an upward inclination with respect to the bottom of the section 2 and in a manner as shown in Figure 2.

Each side of the body portion 42 is formed near its bottom with a lengthwise extending shoulder 44, and said shoulders 44 when the body portion 42 is in position, abut against the lower face of the flanges 23 whereby the said flanges in connection with the bottom of the section 2 will slidably see cure the body portion 42 in position. The shoulders 44 terminate at a point removed from the forward and the rear end of the body portion The plug 41 is of greater length than the length of the body portion 42 so that the plug will project rearwardly therefrom as shown in Figure 2.

Formed integral with the rear end of the body portion 42 is a vertically extending arm 45 having projecting rearwardly therefrom, at a point below the top thereof, an

enlargement 46 formed with a vertically disposed opening 47, and arranged within the opening 47 is a sleeve 48 of insulation which has an extension 49 terminating at the upper end of the arm 45.

Supported by the arm 45 and insulated therefrom through the medium of the insu lation member 43 is an inverted hook shaped contact member 49 which is in electrical contact with the plug 41 and terminal 16. The member 49 extends up through the insula tion member 48, arranged in the enlargement 46, and is bent as at 50 to project rearwardly therefrom and in the path of the terminal 16.

i Vhen the battery 3 shifts towards the section 2 of the pen body, the terminal 15 engages the contact 13 and as the terminal 16 abuts the projecting portion of the member 49 the lamp circuit is closed. The plug holder has its arm 45 abutting against the lug 23. hen the lamp circuit is closed the circuit is set up by terminal 16, member 49, plug 41, plug holder, lug 23, inner shell, section 2 of the pen body, contact 13 and terminal 15.

The reference character 51 indicates a cylindrical protecting cap for the pen point 34 and which is detachably mounted on the section 2 of the pen body and has its onward movement. arrested by a bead 52 formed on the periphery of the section 2 in proximity to its free end thereof. The cap 51 has its closed end formed with an exteriorly arranged peripherally threaded lug 53, which. engages with the interiorly threaded sleeve 12, for detachably connecting the cap to the extension 3 when occasion requires, and further is of a length to force the contact 13 rearwardly to a point in proximity to the terminal 15.

By setting up the battery 8 to shift. in a manner as stated, the lamp circuit will be automatically closed when the pen is in position for writing or when the pen is tilted in a direction. so that the battery 3 can shift to have the terminal 15 thereof engage the contact 13. The battery 8 automatically shifts to open the circuit when the pen is positioned whereby the pen point 34 will extend upwardly, or the circuit is opened by the contact 13 returning to normal position when the lug 53 is out of engagement therewith. f

The section 1 of the pen body can be set up of any suitable material but the section 2 can have the cylindrical part thereof of nonconducting material, and the extension 3 of conducting material, in view of the fact that when the inner shell is mounted in position, it has Contact with the extension 3. The section 2 of the pen body can, if desired, be constructed of conducting material throughout. The cap 51 is preferably set up of nonconducting material.

' It is thought the many advantages of a fountain pen as set forth can be readily understood, and although the pref-erred cmbodiment of the invention is as illustrated and described, yet changes in the details of construction can be had which will fall within the scope of the invention as claimed.
