Improvements in Metallic Pens.
I, ALOIS DIEDRICK LEONARDT, of the Firm of D. Leonardt & Co., of No. 100,
Charlotte Street, Birmingham, in the County of Warwick, Steel Pen Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
My invention consists of the improvements hereinafter described in metallic
pens the said improvements having for their object to increase the durability of
the pen and to give greater smoothness in writing with the said pen.
In constructing metallic pens according to my invention I make the niб of
the pen preferably somewhat longer than usual and double it upon itself at a
short distance from its end the said doubled part being flattened by press tools
before the hardening of the pen the said flattening operation bringing the doubled
parts into close or intimate contact with each other. The width of the nib at
the part where it is to be doubled is preferably less than the extreme end of
the said nib so that the nib in the finished pen tapers nearly to a point as in
an ordinary pen. The extreme end of the nib may be either turned over on
to the back or upperside of the nib or turned on to the underside of the said
nib.

Improvements in metalic reus.
I, ALOIS DIEDRICK LEONARDT, of the Firm of D. Leonardt & Co., of No. 100,
Charlotte Street, Birmingham, in the County of Warwick, Steel Pen Manu-
facturers, 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 hereinafter described in metallic
pens the said improvements having for their object to increase the durability of
the pen and to give greater smoothness in writing with the said pen.
In constructing metallic pens according to my invention I make the nib of
the pen preferably somewhat longer than usual and double it upon itself at a
short distance from its end the said doubled part being flattened by press tools
before the hardening of the pen the said flattening operation bringing the doubled
parts into close or intimate contact with each other. The width of the nib at
the part where it is to be doubled is preferably less than the extreme end of

ordinary pen. The extreme end of the nib may be either turned over on to the
back or upperside of the nib or turned on to the underside of the said nib.
Figure 1 of the accompanying drawing represents in plan a pen blank (after
the piercing of the middle opening a and side slits by b) of the kind employed
in making pens containing my improvements.
Figure 2 represents in plan and side elevation the said blank Figure 1 after the
stamping or pressing operation by which the said blank is shaped or made con-
vex on its upper side.
Figures 3 and 4 represent the next stages in the manufacture of a pen con-
taining my improvements where the point of the pen is formed by doubling
the end over on to the back or upperside of the pen and Figures 3 and 4*
represent the like stages where the point is formed by bending the extreme end
of the nib on to the underside of the pen.
In order to effect the object of my invention it is necessary that the doubled
part should be practically solid or homogeneous and for this purpose great power
is employed in closing the bent part represented in Figures 3 and 3 on to the
back or underside of the pen as is represented respectively in Figures 4 and 4*.
It will be seen from the said Figures 4 and 4* that the doubled part is pressed
into such close contact with the body as to form a practically solid point of double
thickness of metal the writing point having a smooth or rounded surface.
After the stage represented in Figures 4 and 4 the pen is hardened and ground
in the ordinary way and finally the middle slit c is made in the ordinary way as
represented in Figures 5 and 5ª.
Pens made according to my invention will neither spurt nor scratch in writing
and their durability is very materially increased.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as my
invention:
The improvements in metallic pens herein before described and illustrated in
the accompanying drawing the said improvements consisting in making the point
of the pen of double thickness of metal by bending the extreme end of the pen
upon itself and by great pressure or precussion making the doubled part practi-
cally solid substantially as hereinbefore described and illustrated.
