ATENT FOUNTAIN PEN-HOLDER.

SPECIFICATION forming part of Letters Patent No. 354,664, dated December 21, 1886. Application filed January 22, 1886. Serial No. 189,333. No model.)

To all whom it may concern.-

Be it known that I, WILLIAM W. STEWART, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in FountainPenHolders, of which the following is a specification.

This invention relates to fountain pen holders ofthat class wherein the tubular handle or reservoir is closed at its upper end, a duct or ducts being provided at the lower end for conducting ink down to the pen, and for admitting air intothe holder.

My invention relates, principally, to the devices for securing and adjusting the pen and for controlling and regulating'the flow of ink, and it includes several improvements in the construction of fountain-holders.

Figure 1 of the accompanying drawings is a longitudinal mid-section of a fountain penhoider constructed according to my invention and in its most preferred form. Fig. 2 is a fragmentary view of the pen-mounting. Fig. 3 is an elevation of three different forms of keys for securing the pen. Fig. 4 isatransverse section on alarger scale, cut on the line 4 4 in Fig. 1. Fig. 5 is a transverse section on line 5 5in Fig. 1. Fig. 6 is a similar view to Fig. 5, showing a slight modification. Fig. 7 shows the elements of an adjusting device detached. Fig. 8 is an elevation of a sleeve detached. Fig. 9 is a cross section on line99in Fig. l; and Fig. 10 is a detached view showing a slight modification. The remaining views illustrate modified constructions, which will be described hereinafter.

Referring to Figs. 1 to 9, and more especially to Fig. 1, let A designate the pen (or pen-nib,) which is preferably a gold pen; B, the tubular holder or reservoir, which is closed at its upper end; 0, the tubular nozzle in which the pen is held, and D the bar or plug which passes through this nozzle into the reservoir. The holder or reservoir B is simply a tube with the nozzle 0 screwed into its lower end, and a plug, E, screwed into its upper end. The nozzle 0 has a contracted throat,.a, in its upper portion, into which throat the bar D may fit. Beneath this throat it is enlarged to form a chamber, 12, for bold ing the pen, and at its lower end it is further enlarged at c to avoid contact with the pen,

forming thereby the tubular extensionclaimed in my Patent No. 237,454, dated February 8, 1881, for preventing evaporation'and protecting the fingers from being soiled. The bar D has a chamber, (1, at its lower end, formed by a bell-mouth, an external flange or head, 6, a contracted neck, which preferably fits the throat a, and a shoulder, g, to limit the upward movement of the bar in the nozzle. The portion F is tubular and extends above the neckfinto the cavity of the reservoir. A shoulder, h, is preferably formed by making the tubeFsomewhat smaller than the neckf. The tube F and bar D are preferably made in one piece, as shown, a1: though this is not essential. A bore, 1', forming a duct, extends through the bar D and tube F, from the upper end of the latter down to the chamber d. Several branch ducts or vents, jj, lead into this duct i, affording passages for ink or air to flow through either from the duct i into the reservoir or from the reservoir into the duct.

The pen A is held between the flange 0 and the wall of'the chamber 1), a key or wedge, G, being inserted above it to make it tight. There is sufficient freedom of motion when the key is not in place to enable the pen to be tilted or rocked on the flange e as a fulcrum, as shown in Fig.2. In this way the point may be elevated or depressed to suit the requirements of the individual writer who is to use the pen, and to adapt it to Varying conditions as regards the flow of ink and the like.

The degree of elevation or depression of the point of the pen is determined by the form of the keyused. Fig. 3 shows three different shapes of keys, No. 1 being to hold the pen in the position 1 in Fig. 2. No. 2 in the position 2 in that figure, and No. 3 in the position 3. The thickness of the wedge or key, or the force with which it is pressed in, is made also a means of-adjusting the action of the pen. The key bears only on the top of the pen, as best shown in .Fig. 4, and the pen being fulcrumed on the flange 0 the degree of pressure brought to bear upon it by the key has an important influence upon the action of the point of the pen. Thus if the pen be flattened by the key to a certain extent, its nibs will be drawn somewhat apart, causing it to make a heavier mark. The degree of stiffness of the pen may be thus adjusted.

The key G may be applied in three ways. It may be placed on top of the pen, the pen and key inserted into the nozzle, and the bar D inserted afterward and pressed in until the requisite tension is obtained; or the bar may be inserted first, the pen next, and the key last, the key being pressed in from below; or the bar and pen may be inserted, and (the nozzle 0 being detached from the holder) the key may be pressed in from above. The shape of the key and the particular construction of the other parts will determine the method by which it should be inserted.

The key is provided with a duct or channel, is, extending through it, in order to afford a passage for ink to flow through down to the pen, or for air to pass through upward to the holder. This duct is preferably made by cutting a groove or channel in the under side of the key next the pen, as shown best in Fig. 4.. The throat a of the nozzle' has one or more grooves, Z, out in it to afford a continuation of the duct is with the holder. These grooves are shown in Fig. 5. As a substitute the grooves may be cut in the neck f of the bar D, as shown in Fig. 6.

In the preferred construction there are two ducts for feeding the pen, one being on top of the pen and the other beneath it. One of these may be feedingink down to the pen while the other is conveying bubbles of air up into the holder. of the pen is composed of the channels it and l. The duct which extends down beneath the pen is composed of the bore t in the bar D and the chamber d at the lower end thereof. This chamber is closed by a cap, I, which comes close to the open lower end of the plug D, leaving, preferably, a narrow space between, asshown. Through this space the ink may flow out and climb by capillary attraction up to the outside of the bar D to the'pen A, down which it may flow to the point; or the space between the end of the bar and the pen may become filled with fluid, which may thus flow directly to the pen; The inclosing of the bar in the tubular extension 0 prevents the evaporation of the ink from the outside of the bar, and enables the spaces around the bar to act as capillary reservoirs when occasion may require.

The chamber dis, in efiect,the condensingchamber foundin several of my former patents,but placed somewhatlower down or nearer the pen-nib. Its function is to effect a union of the ink and air, the latter entering in the form of small bubbles, which become saturated with the fluid in this chamber and work their way thence up into the holder. The rate of flow of ink to the pen depends, to a consider able degree, on the capacity of this chamber and on the area of the exit-opening therefrom, both of which may be varied by moving the cap I toward or from the end of the bar D.

The duct extending down on top This is adjustable by means of astem or wire, m, having a fine screw-thread, on which stem the cap Iis fastened, and which may be screwed in or out by turning it. A small knob or handle, m, is provided to turn it by. The screw may engage a female thread in the bar D or tube F, or, what is better, in a'small plug, P, which is screwed into the upper end of the tube F. This plug P closes the upper end of the bore t, which can thus communicate with the interior of the holder only through the holes j j. The cap, stern, and plugPare shown detached in Fig. 7.

In order to keep the ink-duct k Z on top of the pen clear and open, Iprefer to arrange in it an irritant, as I term it, (lettered n.) This is preferably a fine gold wire, but it may be a bristle or any other slender and flexible substance, preferably non-absorbent, which has the property of attracting to itself the water of the ink, thus keeping the duct always lubricated with a solvent of the solid constituents of the ink and preventing its being choked by the drying of ink in it.

To prevent the accumulation of large airbubbles in the holder from interfering with the proper capillary flow of the fluid,'I provide one or more capillary rings, J, one only of which is shown. hard rubber, with enough elasticity to permit of a slight compression. It is inserted in the tubular holder by pushing it in edgewise, leaving it in any desired position, where it remains held by friction. A large bubble may form within the ring thus arranged without acting as a stopper or plug to impede the flow of ink, as it otherwise would, since when a bubble is thus encircled by the ring the fluid may flow around the bubble upon the ring itself, which thus enables the fluid to get past the bubble gradually. These rings are particularly useful for holders using small pennibs, in order to reduce the tendency of the ink in the holder to flow down too rapidly.

This ring is preferably of ISO By using more or fewer of the rings J and placing them in different positions in the holder, the flow of ink may be retarded and adjusted as desired.

My longitudinally; arranged rings J are to be distinguished from transverse diaphragms or ribs or other transversely-arranged devices for subdividing the reservoir or choking the flow.

I make no claim to'a perforated partition arranged transversely in the reservoir, as shown in the Patent No. 221,815, dated November 18, 1879. Such a partition favors the stoppage of the flow by the accumulation of bubbles, instead of affording a capillary duct for enabling the fluid to pass around the bubble, as is the purpose of my ring J.

The tube F extends into the reservoir a considerable distance, and'upon it is fitted a tubular adjustable sleeve, H, the upper end of which is cut away on one side, leaving the rein Fig. 8. IVhen in the holder, the tongue acts as a capillary grip for attracting a I body of ink and retaining it in the space between itself and the adjacent inner wall of the holder. Fig. 9 shows this in cross-section. The space between the tongue 10 and the adjacent wall is narrow enough to hold the ink by capillary attraction, while on the opposite side of 2 the ink is subject to the action of gravity. The sleeve H may be turned on the tube F so that the tongue-p'may be brought to either side of the holder desired relatively to the pen A. If turned toward the upperside, asshown, the same as the pen A, the action of gravitation is contrary to the capillary action of the tongue, and the ink will flow more freely down to the pen than ifthe tongue were turned to the under side, as is denoted by dotted lines in Fig. 1, in which case the attraction of gravitation would co-operate with capillary attraction, and a greater mass of ink would tend to remain in the holder.

If the tongue be turned to either side, the action will be modified accordingly. -Thusif the ink flows too freely or too scantily to suit the user of the pen, he need only unscrewthen'ozzle from the holder and adjust the sleeve H" to regulate the fiow to his liking. Theadjustment may be further effected by sliding the sleeve out or in on the tube F.

The sleeve H, with its tonguep, may be made in one piece with the bar D, as shown in Fig. 10, so that by turning the bar the position of the tongue may be altered; but as thisinvolves the disturbance of the fitting and adjustment of the pen A, I much prefer the separate construction first described.

The upper end of the holder, instead of being closed by a simple plug or screw-cap, as heretofore, is closed by means of a screw-plug,

E, which is hollowed out to form a cup or re-' ceptacle, K, for holding an extra pen or pens, as shown. This cup is closed by a cap, L, which screws into or onto it. This cap forms on its exterior the bearing over-which fits the usual cap, K, (shown in dotted lines in Fig. 1,) which protects the pen A when the holder is being carried in the pocket. The cap Lis provided in its end with a series of perforations, as shown, to permit the air to circulate to and from the interior of the pen-receptacle, as it is found that if the latter be hermetically sealed the pens will corrode.

The holder is filled by unscrewing the nozzle O, dropping the ink into the inverted holder 13, and then replacing the nozzle. If the holder is a new one it should not be used im mediately. but should be left awhile for the ink to soak and soften it. When a new holder is first filled the action is imperfect, as the ink is apt to roll out in large drops; but when the hard rubber of which the holder is made has become well soaked the ink attaches itself to it, and thereafter obeys the capillary attraction of the surfaces in preference to the attraction of gravitation, being thereby fed to the pen in proportion to the demand for it.

" I will now proceed to describe some'modifications of my invention with reference to Figs. 11 to 15 of the drawings.

"- Fig. 11 is a longitudinal mid-section of the lower portion of the pen. Fig. 12 is a similar section of the bar D and pen-nib A removed, showing a different construction. Fig. 13 is a longitudinal midsection of the lower part of a pen, showing afurther modification; Fig. let is a transverse section of Fig. 13 on the line 14 14:. Fig. 15 shows the pen-nib detached.-

In the construction shown in Fig. 11 the barD fits quite loosely in the neck of the nozzle C, so that when the pen A is wedged in place the rib e on the bar rests against the opposite wall of the nozzle. The channel Z in the neck of the nozzle is large enough to admit the key G through it when the bar D is in place. The key is introduced from above or from the end of the nozzle,which enters the holder B. The pen A rests on the rib e 'as a fulcrum, so that it may be tilted up or down by the insertion of a key, G, having a greater.

or less taper. The bar D, below the rib e, is formed with atubular neck, Q, which curves toward the pen A, and terminates with its open end against the under side thereof. Thus the bore or duct t is continued down to the pen instead of terminating. in a condensingchamber. The key G has a duct, k, formed through it in contact with the upper side of the pen, as already described.

Fig. 12 showsa modified construction of the bar D and condensing chamber (1. This chamber,instead of having an adjustable metal cap or disk, as before, is made with a rubber cap, I, which is screwed to'the end of the bar D. This cap is perforated with fine holes, which admit the passage of ink from the chamber (1 and the entrance of the air thereto. The flow is regulated by increasing or diminishing the capacity of the condensingchamber. This is done by a pl unger,R,wh'ich is movable longitudinally in the bar D, and the lower end of which projects more or less into the chamber. It is preferably screwthreaded,engaging a thread in the bore of the bar, and having a head, 1", at its upper end by which to turn it. The duct t and lateral branchesjj are formed in the plunger R.

Figs. 13, 14, and 15 show a construction that is well adapted to ladies pens. The pen A has a grooved bar or duct, is, fastened upon its upper side, preferably, by riveting, as shown, or in any other convenient manner. Under the pen is the bar D G, which passes through the throat of the nozzle into the holder. The lower portion of this bar is made of wedge shape on its lower side, as shown in Fig. 13,

so that it acts as the equivalent of the wedge.

shaped key G in the former constructions. The rib e, on which the pen A may be rocked as on a fulcrum, is here formed on the inside of the nozzle 0 instead of on the bar D. thus bears downwardly on the grooved bar or duct k, and thus compresses the pen.

The inclination of the pen will depend upon the inclination of the upper face of the bar D G, of which there may be several different shapes, to adapt the pen for different writers. The duct'i and chamber at are formed in the bar D G, as shown. The pen A, with its duct k, is first inserted in the nozzle, after which the particular bar D G which has been selected is pressed in, thereby forcing the pen upward and binding it fast. This construction is in great measure a reversal of my preferred construction, by which, however, the same or very similar effects are secured.
