RESERVOIR-PEN 'OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 754,000, dated March 8, 1904.

Application iilecl August ll, 1902.

To all whom t may concern:

Be it known that I, ALEXANDER MUNRo, a subject of the King of Great Britain and Ireland, and a resident of Stockport, England,

5 have invented certain new and useful Improvements in Reservoir-Pens or the Like, of which the following is a specification.

This invention relates to what are commonly known as reservoir or fountain pens; and its object is to insure a proper flow of the ink whenever the pen is required for use, to provide means for drawing any ink that may remain on the pen-nib after use back into the reservoir, and to allow of the reservoir being lled without inconvenience.

I/Vith fountain -pens as at present made the ink often flows too fast or refuses to iiow until the pen has been violently shaken, while after use the ink is often allowed to remain on the lpen-nib land become wasted by evaporation or otherwise.

According to this invention I employ an arrangement of devices within or about the pen which constitute a pump capable of being worked by the users finger while writing and when operated in one direction serving to draw ink into the pen and by continued action rfill the reservoir and when operated in the opposite direction serving to eject the ink and feed it onto the nib-point. In conjunction with such feed devices I may employ means for wetting or cleaning the nib-point prior to writing.

On the accompanying drawings, Figure 1 illustrates an exterior View of a fountain-pen tted with my invention. Fig. 2 illustrates a longitudinal section of Fig. 1 to a larger scale. Figs. 3 and 4 illustrate like views (in part) but with certain of the devices removed. Fig. 5 illustrates a sectional plan of Fig. 4. Fig. 6 illustrates a transverse section of Fig. 4on the line a b. Fig. 7 illustrates a transverse section of Fig. 2 on the line c d. Fig. 8 illustrates a further longitudinal section, but upon another plane to that shown in Fig. 2 and showing a modification. Fig. 9 is a plan of certainparts shown in Fig. 8. Figs. 10, 11, 12, and 13 illustrate details. Fig. 14 illusstrates a transverse section of Fig. 8, and

modifications. Fig. 18 illustrates a side eX- terior view in part, and Figs. 19 and 20 transverse sections of two further modifications, Fig. 2l being a longitudinal section.

Referring to Figs. 1 to 13, 1 is the penholder, wherein is formed a cavity 2. In the opposite end walls of such cavity are small holes 3, leading, respectively, into the ink-reservoir 4 and to the pen-nib 5. Within the said cavity (the oor of which, as shown, is semicircular) and projectingthrough the said holes 3 is an india-rubber tube 6. This tube is by preference of the shape shown in Fig. 13, having anges 7 and 8, so that after passing through the holes 3 such ianges serve to hold the tube in its proper place and to resist any tendency of being pulled out. It may, however, be of other shapes and be held in other ways, such as by an adhesive substance. Also within the said cavity is a wheel 9, mounted on an axle 10, the ends of which take their bearings in small recesses 11 in the opposite sides of the cavity. (See Figs. 5 and 7.) Upon the said wheel are studs 12, preferably two in number, and upon each stud is an antifriction roller or sleeve 13. The wheel 9 lies to one side of the tube 6, and the rollers 13 lie directly over the tube 6 and in the same v plane. The position of the rollers relatively to the wheel center is also such that as the wheel is rotated the rollers roll and press upon the tube, thereby attening the tube, as shown in Fig. 2, and diminishing or closing the passage for the. ink at the point of contact, the tube, due to its own elasticity, eX- tending or expanding again as soon as the roller has passed.

To one end of the india-rubber tube is connected an ink-feeder consisting by preference of a small tubular part 14, terminating at one end in a plate 15, which loosely lits the channel of the pen-nib 5, and at the other end terminates in an enlarged tubular part 16, Which iits over the anged end 17 of the india-rubber tube, as shown in Fig. 2, and thereby connects the feeder and tube to each other. The said enlarged part of the feeder is held in position within the holder by fitting tightly or screwing into a metal vpiece 18, carried by a rod 19, which in turn is secured to the split IOO steel nib-holder 20. (See Figs. 11 and 12.) With the parts thus assembled the user may charge the ink-reservoir 4 in the ordinary way through the removable end 21 or he may charge it by dipping the pen-nib into a supply of ink and by constantly rotating the wheel 9 pump it in through the tube 6.

To prepare for writing, the wheel 9 is rotated by, say, the users finger-tip until the ink reaches the pen, each traverse of one of the rollers along the tube serving to drive for; ward a portion of ink.

After using the pen and desiring to prevent the waste of ink remaing on the nib the user rotates the wheel backward, and thus causes the rollers to roll up on the tube in an opposite direction, and thereby drive the ink back into the reservoir.

To provide for the more effective flow of the ink and wetting of the nib or to clear the nib of dried or elotted ink, the feeder 14 and its holder 18 may be capable of sliding to and i ro upon the rod 19, and in such connection the retraction of the tube 6 may serve for returning the feeder after it has been moved outward, and to facilitate the moving out of the l feederImay provide a small bent wire 22, se-

cured to the part 18 and after passing through a slot 23 in the holder terminating in a small head 24, so that the user by applying his thumb-nail or linger-tip thereto may readily move the feeder forward and allow the indiarubber tube to draw it back again, the plate 15 thereby rubbing the ink over the point of the nib and making it ready for use. In place of the said Wire 22 I may use a further wheel 25 within the cavity 2 and upon the same axle 10, but loose, as shown in Fig. 14, also a rack 26, (see Fig. 8,) gearing with the said wheel 25. This .rack is a continuation of the part 18, (a small hole being provided for it to pass through,) so that upon rotating the wheel 25 in the direction of the arrow the feeder-plate 15 is moved forward to the nib-point, as shown by dotted lines in Figs. 2 and 8, the tube 6 returning it after the wheel 25 is released.

In Figs. 15 to 17 I show various ways of mounting the wheels and rollers, the rollerstuds 12 in Figs. l5 and 16 being carried by the wheel 9 and a disk 9X.` In such examples the rollers 13 may be on studs secured to both wheel and disk or be solid and have trunnions 13X, taking loosely into holes in the wheel and disk.

In Fig. 17 I show how the axle 10 may pass right through the holder and the wheel 9 be rotated by a loose key applied to the squared end of the axle or by aring; but I prefer the wheel to be rotated as aforesaid.

In Fig. 7 the wheel 9 is fast to the axle; but it may have an elongated boss and be loose.

In Fig. 14 the wheel 9 is fast on the axle, and the wheel 25, with its supporting-boss or sleeve, is loose.

In Fig. 15 the wheels 9 and 9X, together 65 with the axle and trunnions, are formed out of one piece.

In Fig. 16 both wheels and disk are loose on the axle, and the boss of the wheel 9 forms also the boss of the wheel 9X.

When the axle 9 does not pass through the holder, it is sprung into position. The wheels and their rollers may be variously made and mounted, the main requirement being cheapnessA of production and eiiiciency.

The reservoir may consist of a thin rubber bag 27, lying inside the holder and attached to one end of the rubber tube 6, as shown in Fig. 2. Inside such bag I may place avuleanite or thin metal tube 28, perforated with a few holes. The rod or tube serves to keep the rubber bag in position, to conduct the ink,

and to afford a means of aflixing the rubber bag to the rubber tube.

The top end of the holder iselosed by the plug 21,which fits tightly orscrews into the holder, and in such plug I form a small air-hole. When so constructed, it is impossible thatthe ink can spill or leak when the pen is carried in any position in the pocket.

Fig. 11 illustrates a section of the split steel lining 20, which holds the pen-nib pressed against the inside of the penholder. The steel lining also supports at its inner end the rod 19, and the projection 29, which supports the rod, takes into a recess 30 of the penholder and prevents the lining being withdrawn when the pen-nib is Withdrawn. Fig. 10 illustrates a section of the lining 2O 1and the metal piece 18 when the stud 22 is used, as shown in Fig. 2. Fig. 12 is an end view of the lining 20.

The cavity between the wheels may be covered by a small lid or lap, fixed or sliding, and to facilitate the manufacture the wheels and tube may be fitted in a metal box adapted in turn to fit the cavity. I may use the wheel 9 for operating any other kind of small pump; but I prefer the rubber tube and semieircular cavity.

The rod 19, as shown more particularly in Figs. 2 and 11, may be screwed into its place after all the other parts have been litted in. rlhe rubber tube used may also be round or oval in section.

In the illustrations I have shown the wheel 25 mounted on the opposite side of the cavity to the wheel 9. As a modilication it may be mounted adjacent to such wheel. The holder 1 may be made of a larger diameter where it contains the cavity in order to permit of the cavity being made of larger size than would be the case if the penholder was of a uniform size in every part. The cavity itself may also be formed from the side or from the bottom instead of from the top, the essential points being that it should contain part of a circle, whereon the rubber tube may rest, and that it IOO IIO

izo

should permit of a part of the wheel circumference being outside the cavity and convenient to the finger-tip.

Figs. 1 to 13 have particular reference to cases where a U-shaped cavity is employed. In the modifications hereinafter described where a transverse cylindrical cavity is used the whole of the wheel or wheels may lie outside the cavity.

In the Inodication shown in Fig. 19 the transverse cylindrical cavity extends only partly across the penholder. The movable feeder is operated by means of a stud 22, as already described, and the wheel 25 is therefore unnecessary. The rollers 13 are supported on studs 12 on the wheel 9, and a metal liner 2X is used. The liner is of cylindrical shape to fit the cavity, and in it are formed holes to lie exactly opposite the holes 3. One end of the liner 2 is open, and the closed end supports in its center a sleeve or tubular part which serves to hold the axle of the wheel 9. The end of the axle away from the wheel is secured by a nut 31.

In the modification shown in Fig. 2O the cylindrical cavity passes right through the penholder, and I use two disks 32 33, with holes at their centers, to support the'axle 10 and in which the axle revolves. These disks are fixed by their circumference fitting tightly against the substance of the penholder at the ends of the cylindrical cavity. The gear-teeth in this case are preferably formed on a small pinion affixed to and lying on the inner side of the wheel 25, and the rack 26 is bent to pass through a slot in the disk or holder, which enables the rack to be moved as described in order to operate the movable feeder. The wheel 25 is loose on the axle. In this modification it will be seen that I employ two disk-wheels to support the rollers 13. Preferably I form these two disk-wheels and the axle out of one piece of metal, and the wheel 9 is made fast to the axle after the other parts are placed in position.
