FOUNTAIN-PEN CAP.

Specification of Letters Patent.

Application filed April 4, 1912. Serial No. 688,522.

Patented Apr. 22, 1913.

i To all whom it may concern:

. Be it known that I, PHILIP J SCHREIBER, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Fountain-Pen Cap; and I do hereby declare the followin to be a full, clear, and

exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to the characters of reference marked'thereon, which form a part of this specification.

My invention relates to an attachment intended particularly for use in: connection with fountain pens, but maybe used in connection with other kinds of pens if desired, or in any otherconnectionfor which it may be adapted or appropriate.

1 The object of my invention is the provisions of means for use within a fountainpen cap for permanently attaching the cap to the pen barrel for longitudinal move.- ments thereon, and for causing the automatic opening of the outer cap; end to expose the pen proper for writing when the cap is moved rearwardly on the barrel, and. -to close the outer cap end over the pen end when the cap is moved to pen protecting position, thus preventing the liability of misplacing or losing the pen cap, or of breaking the same by reason of its falling,

lowing specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of a fountainpen embodying my invention, with the cap in closed position. Fig. 2 is a similar view with the parts in open position. Figs. 3 and 4 are similar side views thereof turned in difi'erent positions, with the cap in closed position in the latter and partially opened in the former, and Fig. 5 is a detail of the operable parts separate from the cap.

Referring to the drawings, 1 designates the barrel of afountain-pen, and 2 the cap which is mounted for longitudinal sliding movements 'thereover to enable it to be moved into positions to cover or uncover the pen point 3.

In carrying out the feature of my invention, I open the outer end of the ca 2, as shown at 4, and mounta ring 5 preferably of metal therein, adjacent to such outer end. This ring has an arm 6 projecting laterally from the inner end thereof toward and adjacent to the inner end of the cap 2, such arm being rigidly attached to the cap by screws 6, or in any other suitable manner, to adapt such arm to move in unison with the cap.

A slide-bar 7 is mounted in longitudinal parallelism with the arm 6 adjacent to one side edge thereof and has its inner end working in a guide 8 projecting laterally from the inner end of the arm 6 and its outer end working through the ring 5 in close relation to its inner wall, and guided for reciprocatory movements at such end by a pin or lug 9, projecting laterally therefrom through a guide-slot 10 provided in an extensionll on the inner end of the ring 5. The inner or adjacent longitudinal edges of the arm 6 and slide-bar 7 cooperate to form a guide-slot 12 for a pin 13, pro ecting, 1n the present instance, from a ferrule 14, that is threaded or,otherwise suitably attached to the barrel 1 adjacent to its pen point end, to work in.

The pin 13, in addition to servmg to prevent a rotation of the cap and internally attached parts uponthe pen barrel, also coacts with a notch 15 in the rear or inner end portion of the slide-bar 7 to move such bar cam surface 16, which is intended to force the pin 13 laterally into the notch 15when such notch is positioned in opposed relat1on to said surface and the cap carried parts are at a predetermined point in their outward sliding movements, and vice versa. Upon a continued outward movement of the cap carried parts relative to the pen barrel, the

pin 13 is held in engagement with the notch 15 by the surface 16 of thearm 6, thus causing the bar 7 to stand fixed relative to thewhereby the gate is permitted to swing into positions to open or close the open outer end of the cap 2. The gate 17 is preferably of suitable size to fit snugly within the end of the cap 2 against the shoulder formed by'the outer end of the ring 5, and preferably has its inner side faced with soft rub-" ber or other suitable material to enable the gate to have a substantially air tight fit within or against the outer end of the cap.

The opening and closing movements of the gate are controlled by longitudinal movements of the slide-bar '7 relative .to the ring ,5 and fixedly attached parts, and for such purpose has its outer end projected through the ring 5 and pivotally attached to the inner side of the gate 17 in suitable position to effect an opening of the gate when the slide-baris moved forwardl tive to the cap, and to effect a closing of the gate when the bar is moved rearwardly relative to the cap. When the gate is in the full open position shown'in Fig. 2, the pin 9, which projects from the slide-bar 7 is seated Within a laterally curved portion 19 of its guide slot 10, thus tending to .hold the

parts

6 and 7 in their relative positions of adj ustment.

As the cap 2 and associated parts are preferably made of suitable size to adapt them to be mounted on pen barrels of difierent sizes, the rear or inner end of the cap has a reducing ferrule or adapter 20 threaded therein. These ferrules are made in different sizes to adapt their outer reduced ends to have a sliding fit around the pen barrel upon which the cap is 'to-be mounted.

The 0 eration of my attachment is as follows: I en the cap 2 and associated parts are in closed position relative to the pen barrel with the gate 17 closing the open end of thev cap, the slide-bar 7 stands at the limit of its rearward movement relative to the member 6 that is fixed. to the cap 2, and the pin'13 is seated in the slide-bar notch 15,

. being retained therein by the broadened or 1 cam portion 16of such member, asbest LShOWIl in Fig. 1. To uncover the pen point 3 for the purposeof writing, the user is merely required to graspthe cap 2 and move relait rearwardly upon the barrel to the limit of its permissible movement in such direction. During the initial portion of such movement the slide bar is caused to stand stationary relative to the pen barrel due to the pin 13 fitting into the notch 15, thus.

causing the gate 17 to move to the open position shown in- Figs. 2 and 3 due to the rearward movement of its pivot with the cap parts. When the gate '17 has been moved to its full open position, the member 6, which is attached to the cap 2, will have moved'rearWa-rdly a suflicient distance for the cam portion 16 thereof to move into register with the notch 15. to. permit a release of the pin 13 from engagement therewith, thus enabling the member 6 and slidebar 7 to move together during the remainder of the rearward opening movement of the cap 2, which movement places the parts in the positions shown in Fig. 2. When it is desired to close the cap over the pen point the user moves the cap 2 outwardly on the barrel, and when the notch 15 has" been .moved into register with the pin '13 on the barrel, such pin is forced into engagement with such notch, thus holding the slide bar stationary relative to the pin duringth'eremainder' of the outward movement of the cap. The holding of the bar 7 in this man ner during the continued outward movement of the cap and attached member 6 causes the gate 17 to be swung into the cap-closing position shown in-Fig. 1. It is apparent that this attachment prevents a losing of the cap, and provides a simple and elficientprotecti on for the pen point when carrying the pen in the pocket. my invention may be easily attached to any of the fountain pens on the market or tothe 105 It is also apparent that holders of the ordinary writing pens,' as it is only necessary to slip the parts over the pen barrel or holder and to secure the collar or ferrule member 14, whichcarries'the pin 13, in proper adjustment thereon.

I Wish it understood that my. invention is not limited to any particular construction or arrangement of the parts except in so far. as such limitations are specified in the claims;

Having thus described my invention, what I claim as new and desireto secure by Letters Patent, is,-'-
