iMPROVEMENT lN PENS.

The ScheduIe referred to iu these Letters Patent and making part of the same.

II, GnnMoNn CaANonnL, ot' thecity and county ot \Vashmgton,' in Dthe District ot' Columbia, have invented certain Improvements in Writing-Pens, ot'

which the following is a specification.

The tirst part oi" my invention relates -to the construction of the nib7 in such a way as to give increased .depth at the extreme point, to prevent catching on making the upward stroke; also, in constructing the two sections of the nib in such a way as closely to resemble the blades of a drawing or ruling-pen, thereby securing a perfect-ly smooth line in 'the downward stroke.

The second partof my invention relates to the combination of my pen with amovable slide on the top of the pen, by moving which, toward the point, prevents or regulates the flexibility' of the nih, so that it may be used as adrawing-pen, making any desirable width of line.

Figure 1 is a plan view ot' a pen embodying my invention.

Figure 2 is a top view of the same after beine,r formed. M

Figure 3 is a side elevation otA the saine.

Figure 4 is a side elevation with a section removed,

disclosing the loop for holding the ink.

Figure 5 is aside elevation, showing the movable slide h for regulating the flexibility.

.For the shape of the body of the pen, any ot the known forms may be used.

Fig. l represents a dat piece ot' metal as rst eut with the dies.

0n bending the bodyot' the pen in its proper shape, the open space c is closed, the two sections of the nib being tirst twisted or heut inward in the direction ot' the dotted lines c d, as shown in fig. .t; this vbrings the two flatsuri'aces together at the point (l, and cmistitutes the split for the flow oi' the ink.

Should the rounding of the pen fail to close the opening c, a little bend downward, at the point where the dotted line (t 71 crosses, will eii'ect-ually do In the construction ot' metallic pens, heretofore, for tine writing, it was found indespensable to grind each side down until they nearly came to au edge at the point; then, in order to get the proper iexibility, the metal ot' which the pcn was made must also be veryrthin, so that the point ot' the pen when finished was necessarily!sharp, almost like a needle.

Vith such a point it was almost impossible to make the up stroke without one foot of the nih catching and' spatterng the ink, or the entire point penetrating the paper.

The object of my iuvention is to overcome this difficulty, and also to secure a perfectly smooth line, on both edges, in the down stroke. This, I believe, I have effectually accomplished.

By cutting each halt` of the nib broader at the point, at first, and then turning it up edgewise perpendicular to the body of the pen, I secure any desirable depth of point up and down, and consequently can cttectuall y prevent any catching and sputtering o'i' ink, and the possibility of penetrating the paper inl mkaing the up stroke, at the same time securing the line hair line desired.

.By this arrangement of nib, I also secure a Very important feature of the drawing-pen, the two edges corresponding to the blades of that instrument, and, like them, in making the down stroke, each side ot' the nib makes a slightly indented track or channel, by means ot' which the ink is guided, and a perfectly smooth line obtained.

When the point is made ot' the same material as the pen, these edges are formed by turning each section of the nib up edgewise, as stated.

But when extra pieces are added, as in the gold peil, these pieces are to be worked down to au edge on the under part, from the point back, to the same sharpness as at the cxtreme point, so that, ou pressing the peu down for a broader mark, the same thiu edges will he kept on the paper, instead of the const-antly-ncreasiug width from the point back, as iu the present plan.

By means ot' the slide h moving under the loop g, or its equivalent, fig. 5, this pen becomes a very good substitute for the drawing-peu.

Wheli moved forward, as shown in the ligure, it

prevents the spreading of the two parts of the nih,

and therefore secures a tine, even, hair mark.

.By moving the slide a little back, a slight motioi.` is allowed the nib, the sect-ions opening slightly, and consequently a larger line is obtained.

Any desirable size ot' line may be secured in that way, by moving the slide back or forward.

Fig. Lt represents the loop or strap f, secured to the body ot' the pen and extending well toward the point on the under side, for the purpose of holding a larger quantity oi' ink than the pen would otherwise carry. l

This lnay be att-ached tothe pen, as shown in the fi gurc, or fastened to the pen-hoh'ler, as desired.

I claim as my inventionl. Increasing the depth of the nib of ordinary elastic metallic pens, when such increased depth is produced by forming edges ou thc under ,parts of the nib, running back from the point toward the heel of the pen, substantially as and for the purposes set forth.

2. The improved pen, as described, in combination with the slide 71,01' its equivalent, substantially as and for the purposes specified.
