WRITING IMPLEMENT Application. filed October 10, 1930. Serial No. 487,707.

This invention relates to improvements in writing implements and it is the principal object of my invention to provide a pen of simple, and consequently inexpensive construction, yet durable and highly eificient in use.

Another object of my invention is the provision of a writing pen having a pen point permanently attached to a suitab e holder 19 and equipped with a tubular wire body for feeding the ink to said pen point.

Still another object of my invention is the provision of a writing pen having its permanent pen point provided with a plurality of ink feeding grooves through which the ink is gradually fed from said tubular wire body to the point.

A further object of my invention is the provision of a writing pen equipped with a plurality of writing points.

A still further object of my invention is the provision of a writing pen including a tubular body of helically wound wire adapted to engage a holder in such manner as to allow a removal therefrom by turning the point in one direction only.

I furthermore consider as my invention the application of the ink feeding helix and its writing point to a fountain pen of any suitable construction.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds, and will then be specifically defined in the appended 5 claims.

In the accompanying drawings forming a material part of this disclosure: 7

Fig. 1 shows in elevation the preferred form of pen, constructed according to my in 49 vention.

Fig. 2 is a fragmentary sectional elevation thereof, showing the tubular wire body and pen point on an enlarged scale.

Fig. 3. is an enlarged end view of the same.

Fig. 4t illustrates in elevation a modified form of pen having four writing points.

Fig. 5 is an end view thereof on an enlarged scale.

Fig. 6 shows a pen constructed according to my invention in form of a fountain pen,

Fig. 7 is a fragmentary sectional elevation of thelower end of the fountain pen, Figure 6.

Fig. 8 is a cross-section on line 88 of F ig. v 7 on an enlarged scale.

Figs. 9 and 10 are end views of modified forms of my pen, on an enlarged scale.-

As 7 illustrated on the drawings; av pen holder 10 of any suitable shape, color, or ma terial has its lower end reduced, as at 11 and bored in the direction of its longitudinal axis for the receptionof a pen-point 12 held to the holder in anyconventional manner.

T he lower end ofthe pen point has-formed in its walls at oppositely disposed points thereof grooves 13.

A tubular body lat which consists of a helical coil of metal, preferably brass wire is cylindrical at its inner wider end, as at 15, and conically shaped atits outer restricted end 16, and is'wound at its inner end about the reduced end 11 of holder 10 and the shoulderl? formed thereby. The coil will hold the upper end thereof firmly but 'removably on its seat, the direction of the helixdetermining the direction in which the body 14 can be removed from the holder.

In operation, the tubular body is dipped into an ink well or other source of ink supply and the ink heldbetween the convolutions of the coil will gradually be fed towards the lower end of the pen point in grooves 13 and allow writing for a considerable time without leaking or smearing. It will be evident that the lower point 18 of the pen can be formed to suit the various requirements of writers, preferring blunt, or pointed, etc., pen-points.

In Figures 4 and 5 I have shown a modified form of my writing pen according to which the pen 19 may have a plurality of points 20, for instance 4, in which instance a plurality of grooves 21 preferably four, one on each side may be provided and when writing it will naturally be necessary to hold the pen at an appropriate angle to the paper.

In Figures 6,7, and 8 I have illustrated the application of my invention to a fountain pen provided with the usual barrel 22, filler lever 23 and holder for the pen point 24 provided with the grooves 25 for feeding the ink to the point.

The ink is fed from the inker 26 to the spiral or helical spring 27 as above described with respect of the preferred form of my device, through channels 28.

A cap 28 of convenient design may be provided to cover the writing point.

It will be understood that I have described 19 and shown the preferred forms of my invention as examples only of the many possible ways to practically construct thesame and that I may make such changes therein as come within the scope of the appended claims without departure from the spirit of my invent tion and the principles involved.

As shown in Figures 9 and 10 the point of the pen may also be formed by metal blanks 29 shaped as shown and bent inwardly as at 30 and 31 respectively.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A writing pen comprising a holder, a

25 reduced end formed with said holder, a tubular body of helically wound wire having its inner end engaged by said holder and the reduced end thereof and held thereon by the tendency of said wire body to contract and a 39 pen point engaged in said holder, extending through the lower conical end of said wire body and provided with grooves for feeding the ink to its writing point.

2. A writing implement comprising a holder, a helical wire body tubular at one end and conical at its opposite end adapted to receive and retain the writing fluid, said wire body held to said holder by the tendency of the wire to contract, and a writing point 40 held in said holder in the direction of the longitudinal axis thereof, said point having a plurality of grooves formed therein for receiving the writing fluid from said wire body and feeding it to the writing point of the pen.

Signed at New York, in the county of New York and State of New York, this 9th day of October, A. D. 1930.

PAUL SIPTROTT.
