FOUNTAIN- PEN.-

Application filed February 17, 1928. Serial no. 254,955.

My invention relates to pens. V

The object of my invent1on is to provide a dip pen or a-fountain pen with, a .feed plug having a bore for holding an ink-stick into which an ink-stick may be inserted from the exposed front end without disassociating anyof the parts of the pen. g A further object is to provide a fountain pen that may be filled and used with ordinar ink, and that also may be provided wit a stick of indelible inkand filledwith water, which when coming in contact with thefink-stick, will dissolve a portion thereofto provide a writing fluid. A further object is to provide a pen of the self filling type having a feed plug adapted to'hold an ink-stick that may be inserted in the front end of the plug and pushed therethru or therein to be acted upon by water toprovide a writing fluid for the I pen, without disassociating any of the parts of the pen construction.

Referring to the drawings which form a part of the specification, a Fig. 1 is a longitudinal, partly sectional view.of' a fountain-pen embodying my invention.

Fig. 2 is a longitudinal sectional view of the pen section and feed-plug-ill ustrating a modified form of constructionless expensive in cost of construction.)

Fig. 3 is a longitudinal sectional vi wshowinga further feature of construction es pecially adapted for use with dip pens.

Fig. 4 is a cross sectional view taken on line 4-4 of Figure 1, shownon an enlarged scale.

Fig. 5 is a cross sectional view taken on line 5-5 of Figure 1. n

Fig. 6 is alongitudinal planview of the feed-plug with a portion broken away to disclose the relative size of'the ink-duct, pockets and cross bores.

Fig- 7 is a longitudinal sectional view taken on line 77 of Figure 6, and further illustrating said pockets.

*Figs. 8 and 9, are longitudinal sectional views showing the cheapest forms of construction for use with self-filling fountain pens using the ink-stick, but are not adapted for use with dip-pens.

In patents heretofore, granted to me for improvements in pens using an ink-st1ck,1t has been necessary to disassociate the parts in order to insertthe ink-stick, and this defeet has made the pens unmarketable, as the fingers are sure to become ink-stained when the parts are being taken apart to fill or provide a new ink-stick.

L Also,- the diameter of the ink-sticks here tofore used have been too large, preventing I The small diameter of ink-stick, commonly called indelible leads, and used in. pencils,

is small enough to be held in a bore that will notpermit the. ink to flow therefrom at its front end, and therefore I am able. to provide a pen that may be used with or without the ink-stick, and to fill the pen reservoir without disassociating the parts.

In the prior patents above referred to it was necessary to remove the pen section from the body orbarrel of the pen in order to insert the ink-stick in the back end of the feed-plug, and therefore a sack type of reservoir self filling pen could not be used for the reason that the sacksare cemented directly to the backend of the pen I sections; therefore it was necessary dropper to fill the reservoir.

The present invention permits the use of an ink-stick with any type. of self-filling sack pen; f

Furthermore, the pen feed-plug may be made in various sizes to fit any of the standard make of pens, and sold as a separate article of manufacture for use by persons who have purchased'pens of such standard construction..

touse a A, indicates the barrel of a fountain "in which a sack B, held in'the usual manner, and filled in the usual .way.

C, indicates the pen section; which is-attached to the barrel A, by a screw C',.or may be made with a sliding frictional joint'in a manner well known to this art. 7

The-pen section C, isprovided with the usual bore G in which the feed-plug D, is held by friction in the usual manner. The feed-plug D, is rovided with the. usual feed-duct E, whic front end to the back end of the plug as illustrated in Figures 1, 8 and 9, as is usual, or may extend e'ntirely thru the front end as extends from near the I" illustrated in Figure 3, at E, when the pen is to be used as a dip pen, as it permitsthe ink to flow directly from the inkwell into the feed duct at E when the pen is dlpped into said inkwell.

D indicates the lower side of the feed plug.

F, indicates a bore of small diameter which I prefer to have extend the entire length of the feed plug in open communication with the reservoir, and just large enough in diameter to permit anink-stickof small diameter, such as used in Eversharp pencils and which are about fortyfive one thousandths of an inch in'diameter. I may, however, use a smaller diameter if dcsirable, or I may use a larger diameter, such as heretofore used, and when-using ordinary ink, insert a rod of hard rubber in the bore to prevent ink from flowing from the bore by reason of the capillary action not being suflicient to hold the ink therein, as will be readily understood;

The smaller diameter of bore is such that it acts as a capillary tube when the inkstick G, is removed therefrom, and no ink will flow from its outer end Whenthe pen is being used with ordinary ink, and it also serves as a filling channel in filling the reservoir rapidly with ink.

The feed-plug may be provided with one i or more holes H, which extend thru the the penas a dip pen,

partition I, to connect the feed-duct E, and bore F, in open communication, as illustrated in Figures 2367 and 8. In Figures 1+6 and 7, I have shown the passages H, as larger in diameter than. the width of the feed-duct E, to' rovide pockets to hold a larger quantity 0 water in contact with the ink-stick than the smaller holes would hold, which serves to provide the writing fluid or a more uniform color, especially when using that is, inserting the gen point into water to provide a Writing uid, as the fresh water mixes with some of the dissolved fluid from the ink-stick still remaining in the pockets. The capillary holes part of the plug, are made as small, or smaller than the diameter of mit the feed-plug to be and the sediment from the ink-stick as it dissolves, which sediment usually consists of starch grains used to hold the color of the stick.

In Figure 8, I have shown the bore F enlarged in diameter relative to the size of the bore at its forward end, and have shown the holes 'Hlocated nearer the inner end of the plug.

This construction permits a larger drill to be used in drilling the bore for this part of its length, which is an advantage in making the plugs as the small drills break very easily in making a long bore, and this conthe bore F, andpermore easily cleaned ried into the reservoir .mespectivly, formed in the lower removed which collectsstruction' also permits a supply of water being pressed entirely thru the bore as illustrated, or only part way therethru, and'the Water from the reservoir acting on the rear end of the stick only, the color being carto provide the writ ing fluid therein.

ure 9, I have shown the most simple It Will'be understood that the writing fluid provided by the use of the ink-stick is not a true record ink, since it contains no nutgalls or iron, but it serves as a convenient writing fluid for most purposes.

In use, the parts are assembled as illus-- trated in Figure 1, and after removing the cap J, the ink-stick G, is inserted into the bore F, as illustrated and the reservoir then filled with clean water which will come in contact with the ink-stick. and dissolve a portion thereof to provide a writing fluid, as will be readily understood.

If. ordinaryink is to be used, simply fill the reservoir with the ink in the usual way, unless a bore of large size is formed in the ink-plug, in which event'the hard rubber rod havingthe same diameter and length as the ink-stick, should be inserted in the bore before thepen is filled with ink.
