FOUNTAIN PEN-HOLDER.

SPECIFICATION forming part of Letters Patent No. 290,820, dated December 25, 1883. Application led November 6, 1883. (No model.) Patented in England September 14, 1853, No. 4,40l.

T0 all whom it may concern."

Be it known that I, WILLIAM. VALE, a subje'ct of the Queen of Great Britain, residing at Birmingham, in* the county of Varwick, England, have invented certain newand useful Improvement-s in Reservoir or Fountain Pen-Holders or other Vrit-ing-Instruments, (for which I have received Letters Patent in Great Britain, No. 4,401, dated September 14, 1883,) and I do hereby declare the following to be a full, clear, and exact description ofthe invention, reference being had to the accompanying drawings, which form part of this specification.

rI`he object of my invention is to construct pen-holders or other writing-instruments containing a reservoir of ink or writing-fluid, which, by a slight rotary movement imparted to the terminal mount of the holder, causes a supply of fluid to flow to the nibs of the pen or writing-instrument, and on the reverse movement of the mount the writing-fluid instantly recedes again to the reservoir.

The reservoir or chamber for containing the writing-duid consists, essentially, of an elastic or hollow cylinder composed of caoutchouc, india-rubber, or other suitable elastic material, the upper end of which said elastic tube or reservoir is connected to a short length of metal tubing (hereinafter called the i reservoir-mount) closed at its bottom. The said reservoir-mount has an external collar formed at its junction with the elastic tubular chamber, and immediately above the said collar the mount is wormed for a short distance with a slow-threaded screw, and above the wormed part is left plain.

'Io the lower end of the elastic reservoir the pen-holding mount is attached, and running in the aXis thereof a small tube, bent at its end, conveys the Writing-fluid from the reservoir to the nibs of the pen. A tubular casing or barrel, screwed internally at its upper end, incloses the elastic reservoir, and connects the top andbottom mounts. The internal screwed part of the barrel or casing takes into or engages with the screw of the reservoir-mount. The -terminal capk for operating the reservoir covers and is attached permanently to the reservoir-mount, so that the operating terminal mount and t-he reservoir-mount described move together.

rlyhe action on propelling the terminal mount of the pen-holder is as follows: On the reservoir or chamber having been supplied with writing-fluid, -on propelling the holder, the reservoir-mount is rotated, and advanced axially within the internal screw of the casing, so that the elastic or yielding reservoir is twisted spirally through its entire length to an extent dependent on the amount of propulsion. The effect produced by the twisting described is to reduce the capacity of the reservoir, and consequently to urge or drive forward the writing fiuid through the conveying tube or channel to the nibs of the pen, thereby supplying the said pen with an intermittent quantity of ink as the act of propelling is from time to time repeated. The motion of propelling is limited by the abutmentedge of the propeller-mount, and the repelling by a stop on the reservoir-mount coming against the shoulder of the screwed part in the inclosing case or barrel. On rotating the propeller-mount in the reverse way than that as before described, repelling is edected. n

The twisted and partially contracted caout chouc tube or elastic is uncoiled or straightened out, resuming its normal state, and in so doing theinl: left in the pen (or for refilling the reservoir) instantly recedes or flows up the conducting-tube into the reservoir, as before described. Therefore the pen-holder or writing-instrument both propels and repels at pleasure.

I will now proceed to describe, with reference to the accompanying drawings, the inanner in which the same is to be performed.

Figure l represents in front elevation, and Fig. 2 in side elevation, partly in longitudinal vertical section, a reservoir or fountain pen-holder constructed according to my yinvention, the reservoir being filled ready for use. Fig. 3 shows the same in action, the ink in the reservoir being forced therefrom by 9 ceiling spirally the chamber or reservoir, as represented. The other Figs. 3", 4, 5, 6,7, 8, 9, and l0 represent the parts separately.' Fig.

4 is the outer casing ofthe holder. Fig. 5 is an elevation of the propelling-cap. Fig. 6 I

shows a section of the barrel inclosing the reservoir. Fig. 7 shows in elevation the reservoir with its top and bottom mounts. Figs. 8,l 9, and 10 show in section the principal parts separately.

The same letters indicatethe same parts in the above figures of the drawings.

a is the reservoir or chamber, composed of caoutchouc or india-rubber, for containing the reservoir of ink or writing-fluid. The upper end, a2, of the elastic chamber or cylinder a is connected to a terminal mount, b, closed at its lower end. The mount is wormed externally with a slow-threaded screw, b2. This res# ervoir-mount is connected permanently by soldering, or otherwise, to the terminal or operating cap c, so that this cap and the mount b move together when operating the pen-holder. The lower end, a, ofthe elastic reservoir a is connected to the pen-holding mount d, and in the axis of the said mount a tubular channel, di, communicates with the reservoir of ink, and through which said channel inl; or writing-fluid flows to the nibs of the pen e. fis a tubular casing or barrel inclosing the elastic or yielding reservoir a, and connects the top mount, I), and bottom mount, d. The said inclosing barrel or casing f is screwed internally at f2, which takes upon or engages with the screw b2 of the mount b. The barrel f is surrounded by an external covering, g, of vulcanite or other suitable material.

In order to supply the pen with inl: or writing-fluid, the action of the parts is as follows: rlhe reservoir or chamber having been supplied with the necessary writing fluid, on propelling the cap o, Fig. 2, the reservoirmount b is rotated and advanced axially down the barrel f through a distance proportionate to the amount of propellingby b2 of the mount b worming within the screw f2 of the barrel f, ad at the same time the cap e is lowered or ad. anced within the upper end of the barrel, in` which end c2 of the cap c slides, thereby diminishing the distance (as in FiO. 3) between the end of the barrel and collar or stop c, which limits the motion of the cap within the barrel, so that in consequence of the mount b, attached to the upper end, af, of the elastic or yielding chamber, having been turned or rotated several times by thepropelling action of the cap (while the lower end, a, of the said reservoir is held stationary) it acts upon the elastic or yielding reservoir, so as to twist it spirally through its entire length, as represented in Fig. 3 of the accompanying drawings. The effect produced by the twisting described and represented is to reduce the internal capacity of the reservoir, and consequently to urge or drive forward the writing fluid through the channel d?, and conveying-tube d tothe nibs of the pen e, as shown at Fig. 3, and thereby supplying the said pen with an intermittent quantity of ink, as the act of propelling is from time to time repeated. The mot tion of propelling, and consequently the twisting of the ink-reservoir, is limited by the abutment ci of the cap e, while the repelling is limited by the shoulder b3 of the mount b,com ing against the under side, f5, of the screwed part f2, of the inclosing-barrelf. On rotating the cap c in the reverse way than that as before described, repelling is effected. The twisted and partially constricted caoutchouc or india-rubber tube or reservoir a, as in Fig'. 3, is uneoiled or straightened out, the parts resuming their normal positions, as represented in Figs. l and 2, and in so doing the ink left in the pen or for refilling the reservoir) instantly recedes or flows up the conductingtube by partially i'arefying the reservoir by opening out its folds or coils and increasing its internal area, as shown in Fig. l, so that ink at the mouth of the conducting-tube recedes up the said tube d3 into the reservoirehamber, as described. rlherefore the penholder or writing-instrument both propels and repels at pleasure. The cap 7L, Fig. 4, covers the lower mount, d, when the pen-holder is not in use. Vhen the flow ofink is required to be made continuous instead of intermittent, as before described, a small hole in communication with the reservoir is uncovered. The refilling is effected by temporarily stop-A ping or closing the said hole in order to rarefy the interior of the ink chamber or reservoir by the raising of the point of the screwt out of the seat ai of the passage u, thereby admitting air to the ink-chamber and causing a continuous flow. O11 closing the mouth of the hole u by the point of the screw and repelling the mount, ink flows back into the reservoir for refilling or otherwise, as shown at Fig. 3*.

Having described the nature of the said invention, I wish it to be understood that I claimM l.
