This invention relates to fountain pens, and particularly to the closing up or capping features of pocket fountain pens.

The principal object of the invention is to provide a simplified, conveniently and economically manufacturable, economically salable, and improved fountain pen and capping device therefor, wherein the cap will not be removable from the pen-barrel, and which capping device will be efficient, reliable, strong, and durable.

Other objects and advantages will hereinafter appear.

In the accompanying drawing,Fig. 1 is a longitudinal cross-sectional elevation of the fountain pen of this invention.

Fig. 2 is a view similar to Fig. 1, but showing the fountain pen as it appears with its cap drawn away when the pen is in operative condition.

Figs. 3, 4 show a front and side elevation respectively of the pen-barrel, as it appears before assemblage of the pen during manufacture.

Figs. 5 to 10 show details of the fountain open capping device.

Figs. 11, 12 show modifications of the invention.

The cap I of the fountain pen 2, Figs. 1, 6, is completely open at it's terminal 3, and has a cylinder 4 fixed therewithin provided with a pair of opposite parallel elongated slots 5, Figs. 7, 8, the cap being provided with the usual pocket clip 6, as shown. On the periphery of the ink carrying barrel 7 are formed guiding lugs 8 for the slots 5, whereby the cap I may be slid over the barrel forwardly to the upward position shown in Fig. 1 or rearwardly backwardly to the lowered position shown in Fig. 2. The barrel 1 is also provided with a slotted depression 9, Figs. 3, 4, in which is inlaid a T-shaped metallic lug 10 consisting of a vertical strip II and crosspiece 12. Within cap I, at its terminal 3, is located a collar 13, Figs. 6, 10, which is held in place by a pair of pins fixed to the cap passing slidingly through slightly elongated holes in said collar, as illustrated, the holes 15 permitting a small limited vertical sliding movement of the collar 13, which is thus held and guided by the pins 14. To the collar 13 is held a lid 16 for the terminal of cap I by means of a hinge 17, whereby the open terminal of the cap may be thus opened and closed, and to a lug 18 depending from the underside of said lid is in turn hinged at 19 a bar 20, Figs. 9, 10, which is thus suspended from the lid 16 and is located between the barrel 7 and the cap I, as shown in Fig. 2.

The bar 20 is provided with parallel strips 21 forming a slot 22, springy lateral bends 23 in the said strips, and laterally projecting terminals 24, as illustrated in Fig. 10. In the assemblage of these parts, the strip I I lies between the strips 21 for lateral guidance and directioning of the bar 20, the projecting terminals 24 are engageable with the fixed cross-pieces 12 during completion of the upward forward movement of the cap, and the springy bends 23 a tensional frictional engagement of the bar 20 with the surface of depression 9 of barrel 7 as well as the interior surface of the fixed sleeve 4 of cap 1.

During non-use the fountain pen and all its parts appear as shown in Fig. 1, with the lid 16 closing up the cap 1. When it is desired-to use the pen, the cap I is drawn dowrngardly rearwardly, and thereupon the bar 20 ihitially actuates the lid 16 to open up to the position shown in Fig. 2 about its hinge 17. This opening action is automatically performed by the bar 20 pressing upwardly upon hinge 19 and lug 18, since said bar is initially relatively at rest, due to its frictional and tensional engagement with the barrel 7 and cap I, the elongated holes 15 simultaneously permitting limited movement of the collar 13 and hinge 17 required during swinging action of the cover 16. During downward movement of the, cap I to the ultimate position shown in Fig. 2 the bar 20 is carried along therewith and the lid 16 is disposed to the location shown, exposing the pen point 7a for operating writing requirements. When it is desired to close the pen, the cap I is slid forwardly upwardly, carrying with it its dependent parts and lid 16, and just before completing its stroke the lid 16 is swung backwardly and caused to firmly, lockingly, and efficiently close the cap, as illustrated in Fig. 1. This closing action of the lid is automatically performed by the engagement of the projections 24 of bar 20 with the transverse strip 12, just prior to the completion of the upward stroke of the cap 1, which causes the bar 20 45 to pull the lid 16 and swing it to a locked closing position over the terminal of cap I. It will be noted that due to the automatic opening and closing actions of the lid 16 there is precluded any contact thereof with the pen point 7a. " If desired the pen barrel 7 may be provided with a scabbard 30, to conceal the showing depression 9 when the fountain pen is in closed state, as illustrated in Fig. 11.

According to the modification shown in Fig. 12, the ink carrying barrel 7 is provided with an automatic magazine pencil device 31.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:A fountain pen having the combination with a pen and an ink carrying barrel for said pen, of a cap for said parts including a sleeve over said barrel being longitudinally slidable thereover from a position of covering the pen to a rearward position to uncover said pen, a collar held to said cap within its terminal, a lid hinged to said collar to open and close the cap, a bar hinged to said cap lying longitudinally between the cap and barrel and frictionally engaging the cap and barrel, said frictional engagement of the bar causing it to open said lid upon initial rearward movement of said cap and to close said lid upon termination of the forward movement of the cap, and said collar being longitudinally slidable in said terminal to facilitate the opening and closing action of said lid.
