FOUNTAIN-PEN.

7 Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed August 11, 1914. Serial No. 856,265.

To all whom it may concern:

Be it known that I, FREDERICK C. Bins, a citizen of the United States, residing at Macon, in the county of Bibb and State of Georgia, have invented new and .useful Im-,

provements in Fountain-Pens, of which the following is a specification.

The present invention has reference to fountain pens, and it proposes, briefly, an improved cover for pens of this general type which is so constructed as to enable it to fit upon either end of the pen and, when in place upon the point end, to provide for an extensive air circulation, which serves to prevent sweating and other pen trouble arising from heating.

An embodiment of the invention illustrated in the accompanying drawing, whereof Figures 1 and 2 are, respectively, a plan View and a side elevation of a fountain pen equipped with the improved cover, the latter appearing in section in Fig. 2; Fig. 3 is an enlarged, transverse section taken on line 33, Fig. 2; Figs. 4 and 5 are views similar, respectively, to Figs. 1 and 2, but showing a modification; and Fig. 6 is a detail view of the cover in the modified form.

The pen 7 represented in Figs. 1 and 2 is, in the main, of conventional form and, hence, requires no extended description. Its barrel, however, is provided with a rigid centrally-located, circumferential rib or collar 8, which is approximately semi-circular in cross-section and which may be either of the same material as the barrel or of any other suitable material. I

The pen 7 depicted in Figs. 4 and 5 is substantially identical in its essentials to that previously described, and is likewise provided with a collar 8. The cover for the pen is preferably in the form of a cylindrical tube which is closed and rounded at one end and having its opposite end fully open and provided with a retaining device for coaction with the afore-mentioned collar; it may be constructed in any desired length and from either friction or spring metal, or in fact of any other material which may be deemed suitable. In the form disclosed in Figs. 1, 2 and 3, the cover 9 is assumed to be made from spring metal, and its open end or mouth is formed with a longitudinal extension or tongue. 1.0 which. in turn. is provided with a seat or depression 11, this tongue constituting the retaining device above referred to. The tongue 10 is integrally formed with the open end of the cover and is normally straight and in the same plane as the body of the cover so as to avoid the least obstruction to insertion of the op osite extremities of the pen 7 asa whole lnto the said cover. The said tongue, as will be understood, projects beyond the end of the cover whereon it is formed, and 1s designed to have a snap engagement, so

to speak, with the collar on the pen, its seat 11 fitting over the collar, as shown in Fig. 2. Opposite the tongue, there is provided, in this form of cover, a second tongue 12, which may be produced by slitting the cover, and which is designed to bear against the surface of the barrel when the cover is fitted upon either end of the latter, and provides a resilient means diametrically opposite the tongue 10 to permit yielding movement of that part of the cover which engages the pen body so as to relieve the said portion of the open end of the cover of undue strain by reason of the tension exerted thereon when said tongue engages the rib or collar 8. The diameter of the cover is somewhat greater than that of the pen barrel. so that an air chamber 13 will be formed between the side walls of said barrel and cover when the latter is in place, (see Figs. 2, 3 and 5), such chamber communicating with the space or chamber 14 formed within the cover at the closed end thereof. lngress and egress of air to and from the first-named chamber are rendered possible owing to the provision of a pair of vents or apertures 15 which, in the present construction, are produced by cutting away the cover at opposite sides of the main or collar-engaging tongue 10. these vents tapering in width from their outer to their inner ends. In this way, aconstant circulation of air through the cover and around the contained portion of the pen is insured. with the result that the pen is kept cool and sweating and kindred troubles are avoided. Also, owin to the difference between the diameters of the cover and barrel, only a small part of the latter will be in contact with the cover which thus assists in brass or other friction metal, and. with the 1 that the second or auxiliar exception depression 1. are

tongue and seat or omitted, is otherwise. identical with the first, the corresponding parts or features being indicated by the same numerals as in the said first form, but with the rime mark applied thereto. The cover, as a ove stated, may be applied to either end of the pen, and is moved inwardly thereon until the

tongue

10 or 10 projects across the collar and the adjacent side of the latter engages the edge of the cover, the said collar thus acting as a stop to limit the movement of the cover.- In the case of the spring metal cover, the

seat 11 in the tongue 10 snaps over the collar, and the said cover is retained b the pressure of this tongue and of the auxlliary tongue12, while in thecase ofthe brass cover, the tongue "10 has a frictional engagement with the collar. In the latter form, there is also provided. upon the front end of the barrel a second circumferential collar 16', which is designed to hold the pen point in position within the cover 9; that isto. say, this second collar will serve to' center the pen point within said cover during its insertion therein-and, obviously, during the time that the cover is in closed po-- sition, thus maintaining the said point as far as possible away from the wall of the cover. To facilitate withdrawal and subsequent re-insertion of the pen point and spoon, a removable cross-pin, or the like, may be passed through registering openings in said parts, as shown, this pin being indicated in Fig", 2 by the numeral 17 and in Fig.4 by the numeral 17.

Having fully described 'my invention, I

1. The combination with a fountain pen,

of a circumferential collar fixed thereon and having a convex surface, and a'resilient tubular cover having one end fully open and provided with an integral retaining member projecting from the said open end and provided by forming inwardly extending slots in the open end of the cover, the retaining member projecting beyond the open end of the cover to engage the convex surface of the collar, the remaining vportion of the open end of the collar being straight to abut against the said'collar and the open- 7 ings forming the retaining member also serving as vents to admit air into the cover, vthe cover being applicable to either end of the pen to bear upon and project over. the collar in opposite directions.

2. The combination of a fountain pen having a fixed circumferential collar on the intermediate portion of the body thereof,

said collar having a convex surface, and a tubular cover completely closed at one end and fully open at the opposite end and formed of resilient material, the cover at the open end being provided with inwardly projecting openings to form an integral tongue which extends beyond the open end of the cover and formed with a depression in its under side to engage and receive a portion of the convex surface of the collar,

the said tongue being normally straight and in the same plane as the body of .the cover, the remaining portion of the open end of the cover being straight and abutting against the collar to limit the movement ofthe cover, the cover being reversible or apnlicable to'either end of the'pen body and held againstaccidental disengagement solely by the frictional bearing of the tongue on the collar.

3. The combination with a fountain pen having a barrel with an intermediate fixed circumferential collar having a convex surcent to the collar and whereby the portion of the open end of the cover diametrically opposite the tongue is forced in close engagement with the barrel and the collar.

- 4. The combination of a fountain pen having a fixed circumferential collar provided upon the intermediate portion'of its barrel and formed with a fixed surface, and

a tubular cover having one end fully openv and provided withan integral yielding retaining member projecting outwardly beyond the fully open end of the cover and normally in the same plane as the body'of the cover to move over and frictionallv en'- gage the .saidcollar, the remaining portion of the open end of the cover being straight and said open end provided with a yielding tongue at a point diametricallv opposite the said retaining member to relieve the cover of strain when the retaining member en- 7 gages the collar. y

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
