W R KENNEDY GAP FOR FOUNTAIN PENS. APPLICATION FILED ml a, 1900.

v To all whom itmay concern:

WILLIAM lhKENNEDY, OF WASHINGTON, DISTRICT OF COLUMBIA.

Be it known that I, ,WILLIAM R. KENNEDY,

x of Washington, District of Columbia, have invented a new and useful Improvement in Caps for Fountain-Pens, of which the followin is a specification.

his invention relates to a closure or cap intended more particularly for fountainpens, the object of the invention being to rovide; ca "which will be confined on the arrel or bod yof the pen, but which may be moved forward to cover the penoint when the pen is not in use and drawn ack to expose the pen-point when the pen is to be used, thus avoiding the necessity of removing the cap bodily from over the penoint and applying it to the op osite end 0 the pen, as is necessary with ountain-pen caps now in general use.

With this end 'n view my invention consists primarily of a closure or cap adapted to close over and cover the penoint and movable rearwardly on the en bo y or barrel to uncover and expose t e pen-point.

The invention conslsts-also in forming the a cap with a relatively movable portion adaptof the penoint, so as to expose the end of' ed to open automatically when the cap is moved rearward.

The invention consists also in constructing the movable portion of the ca so that it will open laterally, whereby it wil clear the point 5;) tabs pen when the cap is drawn back on the The invention consists also in the details of construction and combination of parts hereinafter described and claimed.

In the preferred embodiment of my invention the cap or closure comprises two conical half-shells adapted when in'contact to close over and cover the point of thepen and separable to uncover the pen-point, the said shells being ivoted to a carrying-sleeve movable alon 51B barrel of the pen, the movement of the s eeve rearward serving to automatically separate the half-shells to uncover the penpoint andacting to carry them rearward free the pen to t e grasp of the fingers for writing; but it will be understood that the invention may be embodied in other forms, as will be more fully described later on and illustrated in the drawings, the essential feature being that the cap or closure will be confined on the Specification of Letters Patent.

pen-body and will be movable rearwardly to uncover and expose the en-point.

In the accompanying awings, Figure 1 is a side elevation of a fountain-pen equipped with my improved cap, the latter being shown in closed position. Fig. 2 is a similar view with the cap in 0 en position and 1etraoted on the pen-b0 y elevation of apen, showlng the cap in longitudinal section and in closed position.v Flg. 4 is a transverse section; on the line a a of Fig. 1. Fig. 5 is a longitudinal section through-a cap of modified construction and in closed position. Fig. 6 is a similar view of the same opened. Fig. 7 is an end -view of Fig. 6 looking in the direction of the arrow in said figure.

Referring to the drawings, referring particularly to Figs. 1 to 4, inclusive, A represents a fountain-pen embodying the barrel portion (1,, carrying, as usual, the pen-point a. B represents my lmproved cap or clo- Fig. 3 is a side sure comprislng two opposing conlcal halfshells b b, pivoted, as at C, to opposite sides of a carrying-sleeve D in such manner that they may be spread apart when the cap is to be opened or closed together over the enpoint, as shown in Figs. 1 and 3, the two alf- I shells being normally and when in closed position held yieldingly closed by means of two curved springs b and b the s ring 12 being fixed at one end to the side of the shell I) and passing horizontally around and bearing with a sprin ressure against the opposite side of the shell while the spring 1) 1s fixed to the side of the shell I) and passes around and bears with a s rin -pressure against the opposite side of iilie s ell b.

When in closed position, the sleeve D and halfshells of the cap are in the position shown in Fig. 1, at the forward end of the penbarrel,'.'with the half-shells held yieldingly together by the springs and conj ointly forming a ca surrounding and covering't e penpoint. 11 opening t e cap when the pen is to be used the sleeve is drawn rearward along the pen-barrel, which action will cause the inner surfaces of the half-shells to contact with the forward end of the barrel, and there rearward movement 0 the sleev serving to draw the two parts of the cap oaok to the r I to the fingers of the user.

point and barrel,

' position illustrated in Fig. 2, thereby ex osmg the pen-point and the adiacent end 0 the barrel, sothat the latter wil be free of any obstruction and will offer a comfortable grasp In order that the cap ma be 'ded in its movements back and fort an prevented from twisting around the barrel, so thatit may maintain its proper relation to the penform in the latter' a longitudinal grooveE, adapted to receive a pin e, carried by the sleeve, the contact of the pin with the ends of the slot acting to limit the forward and rearward movements of the cap 15. and the slot and serving to confine the cap movably on t e pen-barrel. The opposite ends of the slot ma be provided with lateral recesses F, into w 'ch the pin may be I turnedby a lateral twisting motion in order v to lock the cap against. endwise movement when in either of its extreme positions.

Instead of forming the cap with the two spreading or movable sections or shells, as described, but one movable section may be pro- 2 vided, as illustrated in Figs. 5, 6, and 7, where it will be seen that the sleeve D extends forwardly and continuously at one side and is recessed in its opposite side to receive a movable section or door G, pivoted in' the re- 0 cess on a transverse axis 9 and having its outer end adapted to cooperate with and close against the extended end of the sleeve when the latter is moved forward, and thereby close over and cover the point of the pen.

3 5 The section G is acted on by a fiat spring H, fixed to the sleeve and bearing against the movable section and acting to yieldmgly urge it toward the extended end of the sleeve, with which it cooperates. In opening the 0 cap when the pen is to be used the sleeve, as

in the first instance described, is drawn rearward along the body of the pen, which action will cause the section G to open laterally, the continued movement of the sleeve causing 5 the parts to be drawn rearward free of the pen-point and adjacent parts of the barrel,

so that the latter may be grasped for writing.

In both instances described the cap is of such form that it is confined movably on the en-body, so that it may be moved backandorth, its construction being such that when in its forward position it w1ll close over and cover the pen-point and when its rearward position the pen-point will be uncovered 5 5 and ex osed.

Whi eIhave illustrated and described a construction by which the rearward movement of the cap serves to automatically open it laterally, it will be understood that-this is not absolutely essential to the invention.

Instead of providing for the automatic opening of the movable part of the cap it may be so formed as to be opened independently of the movement of the sleeve and before the 6 5 sleeve is moved rearward. It is preferable,

The invention is susceptible of variousqo' modifications as regards the detailed construction and arrangement of the parts. I

believe myself, however, to be the first to provide a closure or cap which is confined'on the pen-body and movable longitudinally thereof and adapted to respectivel cover and uncover the point of the pen; believe myself also to be the first to rovide a cap or closure which islongitudinal y movable on the pen bod and which opens in a lateral direction. I be ieve myself to be the first also to provide a cap or closure which when moved rearwardly along the pen-body will be automatically opened to expose thenpen-point. It isob vious, therefore, that the invention may be embodied in various specific constructions without departin from the limits of my invention, provide the operation is substantially as set forth. I
