FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed January 1'7, 1905. erial No. 241,483.

To all whom it may concern.-

Be it known that I, JOHN A. L. SNYDER, a citlzen of the United States, residin at S0- mls, in the county of Ventura and tate of California, have invented a new and useful Fountain-Pen, of which the following is a specification.

This invention relates generally to fountam pens, and particularly to that class wherein means is provided for controlling the feed of ink to the pen-point.

The objects of the invention are in a novel manner to render unnecessary the removal of any of the parts of the pen to regulate the supply of ink, either to increase or to diminish, or, when desired, wholly to discontinue its flow; to establish a feed of ink to the pen point in the act of removing the cap or closure and to discontinue the feed in the act of replacing it; to regulate the supply of ink as requisite; to prevent bleeding; to obviate any tendency of the ink to clog the ink ducts or channels; to permit ready cleansing of the parts when necessary; to allow bodily disconnection of the pen and its feed from the barrel when required; to facilitate filling; to adapt the pen to be carried in any position either vertical or horizontal, and generally I to improve fountain pens of the character described.

With the above and other objects in view, as Wlll appear as the nature of the invention is better understood, the same consists, generally stated, in a fountain pen embodying a barrel, an ink-feeder rigid therewith, a penholder inclosing a portion of the ink-feeder and adapted for rotary movement thereon, a pen-feeder combined with the penholder, and a cut-off interposed between the penfeeder and the ink-feeder. The construction and cooperation of the parts is such that when the penholder is turned in one direction a flow of ink will be supplied from the barrel by the ink-feeder to the pen-feeder, and when turned in the other direction, the supply of ink will positively be cut off, thereby to prevent any bleeding of the pen when carried in the pocket. The cut-ofl' between the pen-feeder and ink -feeder is yielding in character, so that without undue friction, and thus resistance in turning, a positive seal will be secured between the parts.

Another feature of the invention resides in making the penholder with the pen-feeder and ink-feeder bodily detachable from the barrel, thereby to permit ready filling of the barrel and also to facilitate the cleansing of the parts.

Another feature of the invention resides in the fact that the barrel is adapted to be opened at both ends, the plug or closure employed in connection with the upper end of the barrel, or that opposite the pen-point, permitting ready filling of the pen from that end, thereby obviating the necessity of removing the penholder and its combined parts for this purpose.

Further and more specific details of construction will hereinafter fully appear.

In the accompanying drawings, forming a part of thisspecification, and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a view in elevation, partly in section, of a fountain-pen constructed in accordance with the present invention. Fig. 2 is a view in vertical longitudinal section throught the pen proper, the cap or closure being removed. Fig. 3 is a perspective detail view of the ink-feeder. Fig. 4 is a perspective detail view of a portion of the penholder and inkfeeder, showing the position occupied by the latter when ink is supplied to the pen-point. Fig. 5 is a similar view showing the position of the part similar view showing the position of the parts when the supply of ink is cut off. Fig. 6 is a perspective detail view of the pen-feeder. Fig. 7 is a transverse sectional view taken on the line 7 7, Fig. 2, the ink-feeder being omitted. Fig. 8 is a sectional detail view showing the position of the ink-feeder when the supply of ink is cut off. Fig. 9 is a similar view showing the position of the ink-feeder when the ink is fed to the pen. Fig. 10 is a perspective detail view of the cut off between the ink-feeder and pen-feeder. Fig. 11 is a perspective detail view of the penholder. Fig. 12 is a sectional detail view of a portion of the cap or closure, showing the means combined therewith by which the penholder may be rotated to effect opening or closing of the ink-duct.

Referring to the drawings, 1 designates the barrel of the pen, which is provided on the inner side of each terminal with threads and in termediate of its ends with a circumferential shoulder 2, having oppositely-disposed recesses 3. The end of the barrel that will be the upper one in use is closed by a threaded plug 4, having a longitudinal bore 5, intersecting which is an air-vent 6, the latter being provided to permit the escape of caged air when the plug is screwed home, thereby to prevent bleeding. This plug is readily detachable from the barrel and is removed when ink is to be supplied thereto, thereby obviating the necessity of removing the penholder and the ink-feeder, as will hereinafter more fully appear.

Arranged within the end of the barrel that will be the lower one in use is the ink-feeder, which comprises a shank 7, a head 8 to engage the recesses 3, a pair of shoulders 9 at the base of the head to contact with the shoulder or stop 2, and thus limit the insertion of the ink-feeder, and an abutment 10, disposed at right angles to the length of the shank and adjacent to the shoulders. The ink-feeder when positioned within the barrel is rigid or stationary relatively thereto, and the term stationary hereinafter employed in defining the ink-feeder is to be understood as meaning fixed relatively to the barrel. By preference all of the parts of the ink-feeder are made integral; but, if preferred, theymay be made as separate elements and assembled, and as this will be readily understood detailed illustration of such arrangement is deemed unnecessary.

The shank is housed by a penholder 10,

which is provided at its inner end with an an nular head 11, having at one side of its bore a segmental stop 12, which when the penholder is rotated engages with the abutment 10, and thus limits the rotation of the penholder on both movements either to establish a flow of ink to the penpoint or to cut it off. Adjacent to the head 11 the holder is slightly reduced in cross-diameter to form a bearing 13 to receive a packing 14, which may be of cork, as shown, or of any other suitable compressible and liquid-proof material, this packing being engaged by the inner end of a collar 15, engaging the threads at the outer end of the barrel and serving to compress the packing, and thus expand it laterally to produce an ink-tight joint between it and the in ner wall of the barrel. From the bearing 13 the holder is slightly reduced in cross-diameter and fits snugly within the collar 15, and this reduced portion is frictionally engaged by an internal collar 16, formed on the inner wall of the cap 1.7, the collar operating to ro tate the penholder when the cap is positioned or removed, the twisting movement given to the cap in either of these operations serving to secure the function designed. This feature is one of importance, inasmuch as it renders unnecessary any turning of the holder by hand and further insures the cutting off of the supply of ink when the cap is replaced, which might otherwise be overlooked by the user if dependence had to be placed upon the manual operation of the penholder when the user was through with the pen. As shown in Fig. 3, the shank is a segment-in cross-section, and its chord 18, in conjunction with the inner wall of the penholder, forms an inkchannel 19, Figs.- 8 and 9, through which the ink passes from the barrel into the penholder.

In the lower end of the penholder is arranged the pen-feeder which comprises, as usual, a cylindrical body portion 20 to engage frictionally with the inner walls of the penholder and a beak 21, and in addition to these features, which are common to most pen-feeders, there is combined with the body at the end opposite the beak a teat or exten- .sion 22, which, as well as the body and the beak, is provided with an ink-channel 23, that terminates at a point near the end of the beak. The teat is provided to hold in position a cut-off 24, which is disposed between the pen-feeder and the outer terminal of the ink-feeder. This cut-off may be constructed of any suitable material, preferably of rubber or cork, and is provided in its periphery with a semicircular recess 25, which engages the teat 22, the coaction between the teat and recess operating to prevent the cut-off from turning when the penholder is revolved. In addition to performing the function of a cutofl' the part 24 also serves when the penholder is revolved to rub off from the end of the ink-feeder any accumulation of ink which might operate to clog the ink-channel 19.

The shank 7 fits the inner wall of the bore of the penholder with sufficient frictional resistance as to remain combined therewith when the penholder is removed, thereby obviating the necessity of catching hold of the shank, which would be objectionable on account of soiling the hands. Thus when the collar 15 is detached from engagement with the barrela slight outward pull upon the penholder will remove it and the ink -feeder, thereby leaving the interior of the barrel free for purpose of cleansing or otherwise.

One of the principal features of this invention is the provision of the collar 16 upon the cap or closure 17, which by frictional engagement with the penholder will result in turning the same, and thus positively insure the cutting on or off of the supply of ink to the pen-point.

Of course it is to be understood that the penholder may be adjusted by the fingers to regulate the supply of ink in case the same be so copious as to cause bleeding, but under ordinary circumstances the adjustment of the penholder by the cap relatively to the inkfeeder will be effective in supplying the proper amount of ink.

lVhile the improvements herein described and illustrated are thoroughly effective in use and will secure the functions designed, it is to be understood in practice that changes and modifications as to the structural arrangement of the parts may be adopted and still be within the scope of the inventionj Having thus described the invention,what is claimed is- 1.
