V1 claim. (ci. 12o- 42) This invention relates' to pens, and particularly to that class thereof known as Afountain pens.

It has for its object to produce a fountain pen iiow of the liquid to the pen point when pressed to paper. Y Still another object is to produce a fountain pen in which the ink stick, or other soluble ink element `is placed directly in the barrel thereof.

The invention also consists in certain other features of construction and in the combination.`

and arrangement of the several parts to be here- I inafter described, illustrated in the accompanying drawing as specically pointed outin the claim.

Figure 1 represents a perspective view of the pen, the particular place or position of the -ink stick being shown in dotted lines.

i Fig. 2 represents a longitudinal cross section of the pen showing the interior construction and positions of the several parts.

Fig. 3 is a side elevation of the reservoir and appended parts forming a unit, partly in section 3 and particularly pointing out the positionof the ink stick.

' Fig. 4 is a bottom plan view of Fig. 3.

Fig. 5 is a section along the line B-S of Fig. 3. Fig. 6 is a sectional view of one of the parts conuguous to the tube containing the liquid and fastened thereto.

Fig. 'l is a top plan view of Fig. 6.

Fig. 8 is a longitudinal cross section of the ink stick holder showing the ink stick compartment and the two ducts, or gutters, or slots, one on each side for the full length thereof, and particularly showing that the ink stick compartment does not extend through the said holder from end to end thereof. Y

Fig. 9 is a bottom plan view of Fig. 8. Fig. 10 is a cross sectional longitudinal view of the pen holding member which screws into the member shown in Fig. 6. `u, Fig. 11 is a top plan view of Fig. 10.

Fig. 12 is a side elevation of the feed bar which holdsthe pen point; and I Fig. 13 is a top plan view of Fig. 12. Similar numerals of reference indicate similar i parts throughout the several views.

The invention is constructed and operated substantially and preferably as follows:

I is the outer barrel which is securely fastened to the member 3 as at l; at the further end 5 of the member 3 isV fastenedV the reservoir or water sack 8 as at 1. 3 is provided with two threads on the portion 8; an outer thread 9 which engages with the internal thread III on the cap*` II which is placed over the writing end I2 and writing point or pen I3 when the same is not in use, to protect the same from accidental injury;

4and an internal thread Il which engages with an external thread I5 on the member I2.

Fastened internally on the narrow end of 3 as at I1 is the ink stick holder I8 having an orifice I8 through its center to near the end thereof where the orifice stops as at 20. The ink stick 2| is held in the said orifice I9. .Also there are `two slotsV or lgutters 22 extending the full length of the holder, one on each side thereof. The narrow portions 23 and 24 of 2 extend loosely over the ink stick holder, as more particularly shown in Fig. 2. The member I2 has the usual curvedin portion 25 .to fit the writing nger as well as the feed bar 26 with its feed slot 21 and pen I3.

When the writer desires to insert a new ink stick he unscrews the cap 3| containing a number of extra ink sticks and selects one thereof; he then unscrews the member I2 4from the rest ofthe pen, andholds the said member I2 in the one hand "as a unitary portion, and the other portion of the pen as another unitary portion, as

in Fig. 3, in the other hand. If he should turn the vlast mentioned unitary portion 32, comprising' members I, 6, 3, I8, upside down, no liquid from the sack l6 can ow out thereof; therefore there is no danger of his soiling his fingers; He then holds 32 with its sack downward, as illustrated in Fig. 4, and inserts the selected ink stick in the orifice I9 and brings the said other unitary perr-- tion 33. comprising members I2, I3, 26, against 32 and screws the two unitary portions together as at I4, I5; and the pen is ready to write.

As my invention is in some of its aspects ge neric, I do not limit myself to the particular construction shown and described, but also contemplate the employment of such equivalents as fairly fall within the scope ofthe claim.

In this connection l; may state that although water is specied more particularly for use iny my herein inventionas it is abundant everywhere,

ordinary ink, or any other fluid, maybe employed if desired.

yTherefore it will be understood lthat I may fmake various changes in the forni, proportion,

sizev and detail of the several members shown, having a slot along the side to the full length and the number and position thereof, without de`- thereof, and provided adjacent to its central p0rparting from the spirit of the invention. tion with a perforation which extends, when the I claim: l pen is held in its writing position, upward from 6 In a fountain pen, a barrel, a pen section sleeve the bottom of the bar but only partway thereat the lower end carrying a feeder in the lower through, and an ink. stick mounted in the per- `porti0n thereof and an ink stick holder in its. foration.

upper portion, the said holder comprising a bar WILLIAM F. ELLISON.
