FOUNTAIN-PEN.

sPncIFIcATIoN forming part of Letters'ratent No. 734,563, dated .my 2e, 1903. Appncation med'ntmber 9,1902. serial No. 134,514. (No maar tain new and useful Fountain-Pen, of which' the following is a specification, reference be-A ing had therein to the accompanying drawings.

This invention relates to fountain-pens,the

principal object of the invention being to pro- Avide a pen of the class referred to which is always ready for use and which may be reversed or used either side up, the ink being supplied simultaneously to both sides of the pen-point, provision being also made at the same time whereby air is admitted to the penreservoir at either or both sides of the penpoint to insure the proper flow of ink.

A further object of the invention is to construct the pen holder or clamp in such man# ner that the proper positioning of the penpoint therein will be insured, the placing of the holder or clamp in the body of the pen made easier and more reliable, and the cost of the pen as a whole reduced to aminimum.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination, and arrangement of parts,as hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a central longitudinal section through a fountain-pen constructed in accordance with this invention, said view being taken at right angles to the plane of the pen-point. Fig. 2 is a similar section taken at right angles to Fig. l and omitting one of the pen holder or clamp sections. Fig. 3 is an enlarged cross-section taken through the end portion of the pen.'

Fig. 4 is a detail longitudinal section through the pen holder or clamp sections. Fig. 5 is a plan view of one of the peu holder or clamp sections. Fig. 6 is a plan view of the penpoint. Figs. 7 and Slare edge views of the pen-point, Fig. 8 illustrating a slight modili` cation of the construction shown in Fig. 7.

Like reference-numerals designate corresponding parts in all the figures of the draw- 1ngs.

Referring to the drawings, the pen is seen to comprise the usual barrel-shaped body or `reservoir l, ,havinga tapering end portion 2,

which is made removable from the main bodyI or re)servoir bya screw-thread joint, (shown at 3.

In carrying out the present invention the Vbore 4 of the end portion 2 is enlarged or made, flaring outwardly, as shown at 5, adjacent to the extremity of said end portion` in order to adapt it to receive with a wedging fit the ta-V pering inner portion of the peu holder yor clamp 6.

The pen holder or clamp 6 is preferably composed of twin sections 7, which taper reversely from about the center in opposite directions, as best illustrated in Figs. l and 4, the taper of the inner portions of the sections corresponding with the flare of the outer portion of the bore 4, so that when the sections lare pushed into the end of the body they will be held frictionally after the manner of a lwedge and will at the Asame time securely clamp the pen-point 8 between them.

In order to receive and hold the pen-point 8, the parts 7 of the pen holder orclamp are recessed, as shown at 9, to provide a space equal to the thickness of the pen-point, shouli ders or stops 10 being at the same time formed at the rear ends of the sections 7 to limit the backward movement or insertion of the penpoint, thus permitting the. proper amount of the pen-point to project beyond the outer end of the holder or clamp.

Each section 7 is also 'provided interiorly with a longitudinal groove 11, which forms the ink-duct, the latter extending from the inner end of the holder or clamp nearly to the outer extremity thereof, as shown in Figs. l and 4. Each section is further provided exteriorly with a relatively small groove 12, which forms the air-duct, said groove extending from the inner end of the holder or clamp to a point slightly beyond the center, or, more accurately speaking, beyond the end of the body of the pen when the holder or clamp is in its inserted position, thus permitting air to pass into the reservoir to take the 'place of the ink iiowingtherefrom.

nThe pen-point 8 is perfectly flat, being roo clamped or otherwise cut from sheet metal of the requisite thickness. The pen-point is preferably provided with an ink-holding recess 13, While the point or nib may be enlarged or thickened, as shown at 14 in Fig. Y8, or left the same thickness of the body of the pen-point, as shown in Fig. 7.

From the foregoing description it will be understood that ink is supplied automatically to both sides of the pen-point and that air may enter the reservoir also at both sides of the pen-point. Therefore it matters not which side of the pen-point is used in writing, thus enabling the device to be used either side up. This feature is of special value to rapid writers, who are compelled to frequently lay down and take up the pen. It Will also be observed that the pen is extremely simple to repair and clean, it only being necessary to apply suicient pulling force to the sectional holder or clamp to Withdraw the same from the end portion of the body or reservoir, whereupon the sections of the holder and the pen-point maybe disassociated. In reassembling the parts the pen-point is inserted between the sections of the holder or clamp until its rear end abn ts against the shoulders l0. The holder or clamp as a whole is then, together with the penpoint, inserted in the body or reservoir and pressed inward with sufficient force to enable the holder to beheld Within the daring part of the end portion of the body frictionally or with a wedging fit. The holder or clamp sections are thus caused to bind against the pen -point on opposite sides and securely hold the latter in proper position. A l

Having thus described the invention, what is claimed as new, and desired to be secu red by Letters Patent, is-

l. A fountain-pen comprising a body, a sectional pen holder or clamp seated with a wedging fit in the end of the body, and a penpoint held between the sections of the holder or clamp.

2. A fountain-pen com prisinga body, a sectional pen holder or clamp having a tapering rear end portion seated with a wed'ging fit in the end of the body, and a pen-point held between the sections of the holder or clamp.

3. A fountain-pen comprising a body having a tapering and outwardly-flaring seat, a sectional pen holder or clamp having a tapering rear portion held with a wedging it in the tapering seat, and a pen-point held between the sections of the holder or clamp.

et. A fountain-pen comprising a body, a sectional pen holder or clamp seated with a wedging iit in the en d of the body and provided With oppositely-located ink-ducts, and also having a pen-point recess terminating at the rear in a shoulder, and a pen-point held between the sections of the holder or clamp.

5. A fountain-pen comprising a body hav ing a tapering and outwardly-Haring seat, a pen holder or clamp consisting of sections the inner portions of which are tapered adapting them to be inserted with a Wedging t in the tapering seat, each section being provided with ink and air ducts, a pen-point held between the sections of the holder or clamp, and oppositely-located shoulders on said sections for limiting the insertion of the pen-point.

6. In a fountain-pen, a holder or clamp for the pen-point having means for conducting ink simultaneously to both sides of the .penpoint and also means for admitting air at both sides of the pen-point.

7. In a fountain-pen, a fiat pen-point, in combination with a pen holder or clamp constructed to supply ink to both sides of the pen-point and also to admit air at both sides ot' the pen-point whereby the pen-point may be used either side up, substantially as described.

In testimony Whereof I aiix my signature in presence of two witnesses.
