certain improvements in fountain pens, sov

as to obviate many of the present defects and adapt them to ordinary use, and especially to the useot shorthand writers.

Reference is to be had to the accompany-- ing drawings, forming a part of this speciication-in which- Figure l is a longitudinal vertical section ypartly broken away, of 1n invention ;-an Figs. 2,and\3 are detail views of the spring door and the ink valve, respectively. Fig.

4 is a detail sectional view of the nib end suction is being produced. This dirtics the I end of the pen-holder, so that it has vto be wiped off after every filling. To obviate this, I provide a tubular portion (n) which may be a part of the pen, or a part of the inkfeed, or entirely separate. This tubular portionts the pen-holder quite snugly; and may be further sealed by vaseline, or cement (fn). The ink is drawn up through the tube; and the `pen-holder does not have to ybe dipped into the ink.

My improvements further consist in devicesl for sealing the magazine tube, so that the ink shall not escage when the pen is oarried in the pocket. ack of the opening in the end or the handle, which is intended for the reception of the pen proper, is a slightly enlarged chamber, containing a valve 4(e) and its operating sprin .(f). A s'mall collar (g), having an in passage (19'), is screwed into the inner end of the point section (d) of the pensholder pressing the spring against the valve. he valve has 'small' projections (e), as shawnl in Fi .#3,

- permitting the inlr to pas@ around the vs. ve

and a small packing 'ring (er) is interpose between 'the valve and its seat. operatyknob-like inner end oi the collar 2g) and ving wd (e), preferably attached toward the right hand side of the valve, passes intol the tubular 'pen (71.); and, ,turning to the rlght at (e3), proJects loutward so as to b'e struck by the poin cover (m) at its contracted portion (m when the said cover 1s placed in position. The valve rod (e has a small hole (e2), near its lower end; and a small lug (et) 'on the rim of the tube (a) is bent inward to engage in said hole4v when the valve is o en.

In operation z-- en the pen is removed from the pocket, the point cover is drawn o; and the lower end of the point cover, or

the finger nail, is used to press the projecting part (es) of the valve rod back and upward until the lug engages in the hole. The pen is then ready ,for writin' When the ,pen is'to be replaced in the poiet, the point cover (m), as itis placed over the wrlting point, strikes the projecting portion of the valve rod,automatically disenga es it, and allows the valve (e) to close. he ink is thus-securely confined in the reservoir of the pen-holder; and the pen may be carried in ,any position, or even dropped, without the ink spilling. If the cap should sli oil, while the pen is in the pocket, any acci ental pressure upon the door Z would also be inedective to cause the pen to leak. Before covering the pen point, the handle may be inverted and tapped gently on the table, so as to jar as much as possible of the ink out of the writing point.

Myrim rovements further consist in auto-` matic `iil 111g devices. A small rubber tube (i), closed at one end, is stretched over the tied with a small thread or rubber i. To the side of this tube (d) which is next the back surface ofv the pen-holder, are cemented', or vulcanized,a small tape (Ir), and

a flat bar The tape is to prevent undue stretching of the rubber tube (i) beyond the end `of the bar (j). This tube (t) is covered which is screwed into the point section (ld). This handle section (h) has a small opening (11.' l), directly over the bar (j). A. strong steel spring (l), having a slight enlargement (Z) made to fit the opening (h), is thrust into the handle (h) and engages therewlth so as to be securely hold at its other en gl). The spring is preferably made (see ig. 2) [so that, when free, it opens out conby the handle section (h) of the pen-holder,

siderably more than it is able to do when in .the handle (h) g so that perhaps from two to eight pounds pressure will be required to further collapse it.- Thus the opening (z), which does not lie in such a position as to be ordinarily struck by the ngers, is fairly v well protected against accident. A weaker spring may be used for a ladys pen, which would not be subjected to such hard usage. The point cover (m) is made long enough to cover this opening, when the pen is closed; but it does not cover it when the pen is open. In operatiom-To ll the pen, the tubular part' (n) is dipped into the lnk; the thumb, for an instant, presses the door (Z) and releases it again; and the pen is ready handle containing an ink-retaining collapsiblei tube from which ink is supplied to the writing p oint, a door capable of yielding to pressureJ 1n the outer portion of the handle, and bearing upon the said ink-retaining tube so that when. pressed inwardly it collapses the tube, in combination with a selfclosing air-tight valve adapted to cut ofi' communication between the ink-retaining tube and the Writin pen has been filled t e said door is pressed inwarrf. to collapse the tube, land means under the control of the user for positively holding the valve open when desired.

2. A self-lilling fountain pen, having a handle containin an inner ink-retaining tube, and rovide with an inwardly-opening door in tlie handle, said door being yunder an original strain of outward pressure, so that it will not yield until a certain specied pressure is applied.

In testimony whereof I aHiX my signature in presence of two witnesses.
