FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 408,909, dated August 13, 1889.

Application led January 25, 1889. Serial No. 297,526. (No model.)

T0 all whom t may concern.-

Be it known that I, JOHN D. BRAY, of Montreal, in the Province of Quebec and Dominion of Canada, have invented a new and useful Improvement in Fountain-Pens, of which the following is a full, clear, and exact description.

This invention relates to fountain-pens similar to the one for which Letters Patent No. 405,458 were granted me on the 18th of June, 1889. Such fountain-pen mainly consisted of a combination, with a tubular pen-staff having a feeder at its forward extremity, an opening or aperture in rear of the iinger-grasping portion, and a pen-holder to receive the pen to be fed by the feeder, of a compressible bulb communicating with the interior of the staff through said rear opening and resting when the pen is in use against one of the fingers of the writer.

The invention which is the subject of the present specification differs in some important respects from such construction; and it consists in certain novel constructions and combinations of parts, substantially as hereinafter described, and pointed out in the claims, whereby not only complete control over the ink is obtained while writing, but also when the pen is not in use, and a separate cap to cover the outer end of the feeder is dispensed with.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure l represents a longitudinal section of a fountairpen-that is, fountain penholder with attached pen-embodying my invention and with the feeder as arranged to supply the ink to the pen from below. Figs. 2 and 3 are like longitudinal sections, upon a larger scale, of the front or ink-feeding end portions of the same broken away, and showing, respectively, the parts as adjusted to establish and to shut off the supply to the pen. Fig. 4 is a transverse section upon the line @c ac in Fig. 2. Fig. 5 is a transverse section upon the line g/ y in Fig. 3; and Fig. 6 is a longitudinal section of the forward portion of the fountain-pen, but with the feeder as arranged to supply the ink to the pen from above.

A is the tubular main body portion or reservoir part of the fountain-pen of cylindrical or other suitable shape in transverse section and of any desired size. Said body portion or ink-reservoir tube A terminates in its rear in a solid rod-like extension l), which provides for the proper holding and manipulation of the instrument when in use.

Fitted, as by screw -thread or otherwise, within this tubular reservoir A, at a suitable distance back of its forward end, is a plug B, which has a contracted ink-feeding aperture or duct c in a longitudinal direction relatively to the tubular reservoirthrough it to one side of the center of the plug. Arranged to fit or screw within the front end of saidd tubular reser- Voir A is a forwardly-protruding pen-holder C, which may be provided with a shoulder or collar d, that, when the holder C is fitted or screwed home to its place, bears against the front end of the tube A. This pen-holder C, which is of tubular construction, has a longitudinal duct c in it to one side of the socket portion of said holder, corresponding to the duet c in the plug B, so as to come in line with it when the pen holder C is suitably turned for the purpose, as shown, for instance, in Figs. l, 2, and 4 of the drawings. The penholder C has also a flexible feeding-eXtension @,which bears at its outer end against the pen D, to supply the latter with ink, and which has the duct c extended lengthwise through it, terminating in a contracted aperture at its outer end,whcre it supplies the pen with ink.

E is the compressible bulb, made of indiarubber or other suitable material, and which may be fitted at its ends, as shown in Fig. l, to set into the rod-like extension b and tube A, so as to present an even or flush surface with both.

G is a removable cap on the back end of the rod-like extension h, and which, when the fountain-pen is designed to be carried in the pocket, may be removed from such place and be slipped over the front en d of the instrument to protect the pen.

lVhen the apertured plug B is made of elas- IOO sponding to the feed-hole maybe cemented to it for the socketed end ot the holder (l to bear against, and which will serve as a spring to follow up the holder C when loosened or turned to allow the ink to follow, and so prevent leakage of the ink between the plug B and feeding' pen-holder C,

The tubular reservoir A is provided within the compressible bulb E with the hereinbetore-referred-to aperture s' in rear of the finger-'grasping portion of the instrument.

The construction shown in Fig. G is substantially the same as that shown in the other figures of the drawings, excepting that the feeding-extension e. is arranged to supply ink to the top of the pointed end portion of the pen instead of to its under side, as the manufacturer or writer may prefer. When the feeding pen-holder C is turned or adjusted to bring its duet c in line with the duct e in the plug B, as shown in Figs. l, 2, and 6 ot the drawings, then upon pressing on the bulb E, so as to expel the air contained in it, and at the same time dipping the point ot the feeding-eXtcnsion e into the ink in an ink bottle or stand, and afterward releasing pressure from the bulb, the reservoir A will be charged with ink and will be retained there until expelled by another force. This other force will be the compression of the bulb, which the writer can manipulate, preferably, with his index or fore finger resting in rear of its outer joint on the bulb, so as to supply the pen with ink as required, all as in my former invention, hereinbefore referred to. By the construction of the device, however, as shown in the accompanying drawings, a most perfect control is not only given over the ink while writing, but also when the pen is not in use. Thus by very slightly Jturning or unserewing the feeding pen-holder C, so as to bringl its duct c in line with the duct c in the plug B, ink is supplied lo the pen l) as required, and

by turning said holder C in a reverse direction, or so as to put its duet c out of line with the duet c, as shown, for instance, in Figs. and 5 ot the drawings, the delivery of ink from the reservoir A is shut oit and air excluded, without any extra cap provision, from entering the reservoir.

The instrument may be made oi different sizes and of any suit-able material or materials and its duets as fine or coarse as desired.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a tubular pen staff having an opening or aperture in rea'r of the ifinger-grasping portion and a compressible bulb communicating with the interior of the statt through said rear opening, for operation as described, of a plug or filling within said statt having a feed-duct through it out of line with its center, and a rotatable pen-holder provided with a forward feedingextension and a feed-duet passing through its rear and soeketed at its back in contiguity with the apertured plug in the stall? to put its feed-duet i 11 or out of line with the feed-duet in the plug, substantially as and for the purposes specified.

2. The combination, with the reservoir-tube A, having a rear aperture s, and the eompressible bulb E, of the plug B, having a feedduet c out of line with its center, the apertured elastic washer f, and the pen-holder C, itted to screw within the forward end of the tubular reservoir and provided with a feed* ing-extension e and duct c', for operation in relation with the apertured washer and plug B, essentially as shown and described.
