DRAFTSMANS FOUNTAIN RULING-PEN.

Specification. of Letters Patent.

Patented Jan. 13,1920.

Application filed January 12, 1918. Serial No.'211,'573.

To all whom it may concern:

Be it known that I, EVERETT It. MORE- LAND, a citizen of the United States, residing at Carrollton, in the county of Carroll and State of Missouri, have invented certain new and useful Improvements in Draftsmens Fountain Ruling-Pens; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make.and use the same.

The invention relates to a draftsmans fountain ruling pen.

The object of the present invention is to improve the construction of fountain ruling pens and to provide a simple, practical and efficient fountain ruling pen of strong, durable and comparatively inexpensive construction adapted to 'hold a quantity of ink and capable of positively feeding the same so that the fountain ruling pen may be used continuously without constant refilling as is necessary with the ordinary ruling pen.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: I

Figure 1 is a side elevation of a fountain ruling pen constructed in accordance with this invention.

Fig. 2 is a fragmentary, longitudinal sectional view of the same, the view being taken on line 2-2 of Fig.' 1.

F ig. 3 is a transverse sectional view through the nib adjusting device, the View being taken on line 33 of Fig. 1.

Fig. 4 is a detail view of the feed tube.

Fig. 5 is a detail view in side elevation of the stem.

Fig. 6 is a detail perspective view of a modified form of the feed tube, and

Fig. 7 is a detail View in side elevation of the modified form of the stem.

Like numerals of reference designate corresponding parts in all the figures of the drawings:

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the fountain ruling pen comprises in its construction nibs 1 of the ordinary configuration, preferably formed integral with a head or body 2 which is provided with a sleeve 3 having a threaded con nection 3* with a barrel 4. 'The barrel 4 may be made ofany desired size and it constitutes a reservoir for the ink and it may be readily filled from time to time by unscrewing it from the sleeve or tubular memher 3 of the body or head 2.

The ink flows through the bore or open ing of the tubular member or sleeve and is fed to the outer ends of the nibs by a feed tube 5 having a forked outer portion provided with tapered side portions 6. The nibs are curved in the, usual manner and their outer ends converge. The taper of the forked outer end of the feed tube conforms to the general configuration of the nibs and presents side openings to the inner faces of the said nibs so as to feed the ink to the same. The feed tube is suitably secured at the inner or rear end to the head or body 2 and it is provided with a centrally arranged stem 8 consisting of a small rod or wire and secured at its inner angular end 9 to the inner or rear end of the tube 5, whereby it is maintained in a concentric position with relation to the feed tube. The stem 8 is provided at its outer end with outwardly and laterally curved elastic fingers 9 which extend through the tube 5 and which engage the inner faces of the nibs l to insure the feeding of the proper amount of ink thereto. These fingers also insure the return of the ink to the barrel 4 when the pen is inverted. The stem extends longitudinally of the feed tube and it and the fingers 9 facilitate a free flow of the ink to the nibs of the pen. The ink will flow by gravity and capillary attraction and also the attraction of the paper or other material on which the ruling fountain pen is used. In the modification shown in Fig. 6, the fingers are, as indicated at 9 on the tube 5 opposite the openings in the sides thereof, and the outer end 10' of the stem 8 is tapered and located wholly within the tube.

Owing to the effective means for feeding refilling the pen. The fingers 9 of the construction shown in Fig. 5 and the fingers 9 of the construction shown in Fig. 6 are possessed of a high degree of elasticity, but they will not interfere with the adjustment of the nibs 1 inwardly and outwardly. It will therefore be seen that the fingers will remain in proper engagement with the nibs at all times.

The nibs of the pen are adjusted by means of screw 11 secured to one of the nibs and extending through an opening 12 in the other nib and provided with an adjusting nut 13 which bears against the nib having the opening. The adjusting nut is of the ordinary construction and is provided with a milled or otherwise roughened periphery to enable it to be readily rotated. The screw 11 is provided intermediate of its ends with a bend 14: which arches or straddles the feed tube and enables the screw to be centrally arranged with respect to the nibs. The screw 11 is secured to one of the nibs as at 15 and a washer or plate 16 of any suitable material is interposed between the nut and the adjacent nib.

What is claimed is:

1. A fountain ruling pen comprising nibs, a feed tube disposed between said nibs and having its outer ends thereof forked to provide arms thereby presenting feed openings to the inner side of the nibs, a stem extending through said tube, and outwardly diverging tapering fingers extending from said stem and disposed between said arms and adapted for contact with the inner sides of the nibs.

2. A fountain ruling pen comprising nibs, a feed tube disposed between said nibs and having its outer ends thereof forked to provide a pair of arms whereby feed openings are presented to the inner sides of said nibs, a stem extending centrally through said tube, said stem terminating short of the forward end of said nibs, and outwardly diverging tapering fingers extending from said stem and disposed between said arms and adapted for contact with the inner sides of said nibs, said tapering fingers being elastic whereby they will remain in contact with the inner side of said nibs upon the adjustment of the nibs.

In testimony whereof I aflix my signature in presence of two witnesses.
