SPECIFICATION forming part of Letters Patent No. 278,201, dated May 22, 1 883. Application filed March 18, 1882. (No model.)

To all whom tt may concern:

Be it known that I, JAMES E. TEGARDINE, of Chicago, in the county of Cook and State ot' Illinois, have invented certain new and useful Improvements in Fountain-Pens, of which the following, in connection with the 'accompanying drawings, is a speciiicat-ion.

In the drawings, Figure 1 is a side view of a fountain-pen embodying my invention. Fig. 2 is a vertical central section thereof. Fig. 3 is a detail of the pen-clamp, and Fig. 4 is a detail of the tip or feeder.

Like letters of reference indicate like parts.

A represents the handle, and B the pen.

Gis that part of' the handle which constitutes the ink-reservoir.

D is a diaphragm near the upper end of the This diaphragm has a central conical opening, a, the smaller end of which is downward, as shown.

E is a hollow vertical screwextension on the upper end of the reservoir. In this extension are air-ports a a.

F is a cap screwed upon the said extension. By screwing' this cap up and down the ports a a will be alternately opened and closed.

G is a slender rod or wire depending from the top of the cap F. This rod has a taper point, b, and a conical shoulder, b', the latter ot' which is adapted to close thc opening a.-

H is a hollow extension screwed into the lower end of the reservoir O, and this eXtension has an interior shoulder, c.

I is a tubular piece depending from the upper end ot' the extension H.

J is a split and curved tip or feeder screwed into the lower end ofthe tube I. The split portion ot this feederis inclosed in a rubber sleeve, d.

Kis a point or supplemental tip projecting from and applied to the lower end of the tip J. The pointK rests uponor near the nib oi' the pen, as shown. The upper part of the tip J contains a conical opening, c, into which the lower end of the rod Gtits removably, and immediately below the opening e is a larger channel, e". v

L is a spring-metal clamp, split longitudinally and arranged in the extension H. The pen is slipped in between the extension H and the part L, the spring action of the latter, which is outward, holding the pen removably in place for use.

M is a cover, which, when the pen is iu use, may be slipped removably down over the cap F. When the pen is not in use the cover M is slipped removably on the lower end of the part H, and protects and shields the pen.

In order to prepare the peu for use, I lill or partly till the reservoir G with ink or writinguid, removing the extension H for that pur .pose, and then, after the reservoir has been iilled and the extension H replaced, unscrewing the cap F far enough toopen the air-ports a' a', and by this means also leaving the opening a open, as the conical part b will then stand above the said opening, and also leave open the conical opening c in the tip J. The ink, therefore, depositsitself upon the nib of the pen, and will feed the pen as fast as the ink is shed by writing. in use I cover it with the cover M, in the manner described, and screw down the cap F until the part b enters and closes the opening a, the opening c and ports a a thus preventing the ink from then leaking out ofthe pen. By making the channel c larger than thcopening e any ink-crusts or foreign matter clogging the smaller opening may be pushed down into the larger, where it will escape, the. point ot' the part Gr being forced into the opening ein order to clear it. By splitting the tip J it may readily lbe cleaned, in ease it becomes clogged, the' sleeve d being removed to admit ot' cleaning, and replaced to prevent the ink from escaping, except at the lower end ot' the tip.

it is not absolutely essential that the opening a and the ports a a should he closed at the same time, for it is obvious that the ink cannot leak out ot' the upper end ot' the pen holder or handle when either the said opening or the said ports are closed.

Having thus described my in vention,.what I claim as new, and desire to secure by Letters Patent, isl The combination, with the in k-reservoir and pen, ot' the split feed-tip and its rubber sleeve d, substantially as and for the purposes specied.

JAMES E. TEGARDINE.
