John Street West Birmingham in the County of Warwick Steel Pen Manufacturers
do hereby declare the nature of this Invention to be as follows:-
My invention consists of the improvements herein after described in metallic
pens by which improvements the point or writing part of the pen is prevented
from entering the paper or surface written upon. Spluttering is consequently
avoided and the pen glides over the paper very smoothly. By the said improve-
ments the point or writing part of the pen is kept uniformly or nearly uniformly
charged with ink so long as there is an appreciable quantity of ink in the pen.
In making a metallic pen according to my invention I form on each side of the
point of the pen a small wing or projection preferably of nearly a semi-circular
shape. These wings or projections are bent towards the under side of the pen and
are brought parallel or nearly parallel to each other. The point or writing part of
the pen thus consists of two small curved parallel plates almost in contact the
curved edges of which when the pen is used come into contact with the paper or
Burface and effect the writing. The curvature of the edges in contact with the
paper or surface prevents the pen entering the paper or surface by the pressure
exercised in writing and the capillary attraction of the said plates causes the
space between the plates to be charged with ink so long as an appreciable quantity
remains in the pen.
Instead of making the two wings or projections described a broad pointed pen
of the ordinary kind may have the extremities of its nibs bent inwards so as to
become parallel or nearly parallel. Or the pen may have at its point a small
trough like groove divided longitudinally by the slit of the pen. Both the last
described modifications act in the same way as the first described form of my
invention.

page_text: I JOSEPH LETIERE PETIT of the firm of C. Brandauer and Company of New
John Street West, Birmingham in the County of Warwick, Steel Pen Manufacturers
do hereby declare the nature of my invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:
My invention consists of the improvements herein after described in metallic
pens, by which improvements the point or writing part of the pen is prevented
from entering the paper or surface written upon. Spluttering is consequently
avoided and the pen glides over the paper very smoothly. By the said improve-
ments the point or writing part of the pen is kept uniformly or nearly uniformly
charged with ink so long as there is an appreciable quantity of ink in the pen.
In addition to the advantages already pointed out, pens made according to my
invention possess the further advantage that they are much more durable than pena
in which the points are made in the ordinary way.
In making a metallic pen according to my invention I form on each side of the
point of the pen a small wing or projection preferably of nearly a semi circular.
shape.
These wings or projections are bent towards the underside of the pen and are
brought parallel or nearly parallel to each other. The point or writing part of
the pen thus consists of two small curved parallel plates almost in, contact, the.
curved edges of which when the pen is used come into contact with the paper or
surface and effect the writing. The curvature of the edges in contact with the
paper or surface prevents the pen entering the paper or surface by the pressure
exercised in writing and the capillary attraction of the said plates causes the space
between the plates to be charged with ink so long as an appreciable quantity
remains in the pen.
Instead of making the two wings or projections described, a broad pointed pen
of the ordinary kind may have the extremities of its nibs bent inwards so as to
become parallel or nearly parallel. Or the pen may have at its point a small.
trough like groove divided longitudinally by the slit of the pen. Both the last
described modifications act in the same way as the first described. form of my.
invention.
In order that my invention may be the better understood I have represented in
the accompanying drawing portions of metallic pens drawn to a large scale.
Figure 1 represents in side elevation and Figure 2 in plan of underside the nibs
of a metallic pen the point or writing part of which is made according to my
invention; a, a are the wings projections or flanges formed at each side of the
point of the pen the said wings being bent towards the underside of the pen and
brought nearly parallel to each other and nearly in contact. The said wings a, a
are situated at right angles or nearly so to the nibs of the pen and their edges are
of a nearly semi circular figure. The said curved edges of the wings a, a when the
pen is used come in contact with the paper or surface and effect the writing.
The curvature of the edges of the wings a, a prevents the point of the pen entering
the paper by the pressure exercised in writing and as the wings a, a prevent the
sharp edge of the slit in the point from touching the paper the scratching of the
paper and the spluttering of the pen are avoided.

page_text: It will be seen by an examination of the drawing that the wings or projections a, a
constituting the point or writing part of the pen are nearly in contact, leaving a
narrow space between them which space by the capillary attraction of the said
wings is charged with ink so long as an appreciable quantity remains in the pen :
Figures 3 and 4 represent in side elevation and plan of underside a part of another
metallic pen the point of which is made according to my invention.
In this pen the wings a, a are somewhat broader than those represented in
Figures 1 and 2 and have a different curvature the lowest part of the curve being
situated nearer the point of the pen than that represented in Figures 1 and 2. It
will also be seen by reference to Figure 4 that the wings a, a are not parallel as in
Figures 1 and 2.
Figures 5 and 6 represent in side elevation and plan of underside, a part of
another pen made according to my invention. In this modification the wings a, a
are shorter than those represented in Figures 1. 2. 3 and 4 but the curved edges of
the wings which when in use come in contact with the paper have nearly the same
shape as corresponding parts in Figures 3 and 4.
Figures 7, 8 and 9 represent in side elevation, plan of underside and end elevation
respectively, a part of another pen made according to my invention. The wings a, a
in this modification resemble in shape and size those represented in Figures 5 and 6
excepting that the junction of the two curves of the wing is situated nearer the
point of the pen than in the arrangement Figures 5 and 6. Figure 10. 11. 12
and 13 represent parts of other metallic pens in which the wings a, a are elongated
backwards, the wings in the arrangement Figures 12 and 13 being of less depth
than those in the arrangement Figures 10 and 11.
The wings of the pens in the arrangements represented in Figures 3 to 13 both
inclusive do not differ in their action in any essential respect from the wings of
the arrangement represented in Figures 1 and 2; that is to say, the wings at the
point of the pen come in contact with the paper in writing and the ink from the
nibs readily passes by capillary attraction to the narrow space between the wings
as herein before fully described.
Figure 14 represents in side elevation; Figure 15 in plan of upperside and
Figure 16 in end elevation, a portion of a pen in which a trough like groove is
situated between the two wings a, a. In this arrangement portions of the wings
are bent upwards above the level of the middle of the nibs of the pen, the upwardly
bent parts of the wings forming between them a trough like groove b on the
underside of the pen into which the ink flows by capillary attraction.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I claim
as my invention of "Improvements in metallic pens,"
First Forming on each side of the point or writing part of the pen, a small
wing, projection or flange the said wings, projections or flanges being bent towards
the underside of the pen and at right angles or nearly at right angles to the nibs of
the pen and parallel or slightly inclined to each other and nearly in contact
substantially as and for the purposes herein before described and illustrated in
Figures 1 to 13 both inclusive of the accompanying Drawing.
Secondly-The modification herein before described and illustrated in Figures 14.
15 and 16 of the accompanying Drawing in which a trough like groove is formed
on the underside of the point between the wings, projections or flanges.
