An Improved Drawing Pen for Making Dotted or Broken Lines.
1, DENIS RIPLEY BROADBENT, of Linden Colwall, near Malvern in the
County of Worcester Gentleman, do hereby declare the nature of my said
invention to be as follows:-
My invention has for its object an improved drawing pen for making dotted or
broken lines without the necessity of lifting the pen from the surface of the paper
as in the case with the ordinary inking pen and I may also produce a series of
broken or dotted lines with the same instrument and by a single action of the arm.
My pen is formed with an ordinary handle but with an open ended chamber at
the lower end which is oblong in cross section. At the lower part of the chamber
I hang upon a pivot a notched wheel or there may be two, three or more of such
wheels. At the upper part of the chamber I form a channel which communicates
with the inner parts thereof. Into this channel or opening I fit a trough like plug
the lower end of which finishes with a hair or other brush the end of which just
touches the upper portion of the periphery of the notched wheel or wheels.
When the pen is to be used the trough like plug is taken out and is filled with the
required kind of ink by a pointed glass syringe having a rubber capsule at the back
end. The front end is placed in the trough of the plug and the capsule squeezed
when it is immediately charged with ink and ready for use.
Dated this 29th day of July 1895.

COMPLETE DI MULTICATION.
An Improved Drawing Pen for Making Dotted or Broken Lines.
I, DENIS RIPLEY BROADBENT, of Linden Colwall near Malvern in the
County of Worcester Gentleman do hereby declare the nature of my said inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
My invention has for its object an improved drawing pen for making broken or
dotted lines without the necessity of lifting the pen from the surface of the paper
as in the case with the ordinary inking pen and I may also produce a series of
broken or dotted lines with the same instrument by a single action of the arm.
My pen is formed with an ordinary handle but with an open ended chamber at.
the lower end which is oblong in cross section. At the lower part of the chamber
I hang upon a pivot a notched wheel or there may be two, three or more of such
wheels. At the upper part of the chamber I form a channel which communicates
from the inner parts thereof. Into this channel or opening I fit a trough like plug
the lower end of which finishes with a hair or other brush the end of which just
touches the upper portion of the periphery of the notched wheel or wheels.
When the pen is to be used the trough like plug is taken out and is filled by the
required kind of ink by a pointed glass syringe having a rubber capsule at the back

when it is immediately charged with ink and ready for use.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which examples
of my invention are illustrated sufficient to enable it to be applied to any other
circumstances met with in practice.
Figure 1 is a side view of one of my hand pens complete for forming dotted or
broken lines.
Figure 2 is an enlarged section of the lower part of the instrument.
Figure 3 is a section at right angles to Figure 2.
Figure 4 is a device for filling the trough with ink.
Figure 5 is an enlarged view of the inker a".
Figures 6. 7 & 8 are alternative modes of constructing the wheel B.
My new instrument A is composed of the handle or upper part joined on to the
lower metal portion a¹ or the whole may be formed from metal as will be readily
understood as for instance a complete stamping may be made in two parts so as
when brought together and soldered the whole would be complete for the addition
of the inking plug a² and the wheel B with the spindle as. I do not however
confine myself to the mode of making the instrument but the essential feature is
the lower portion consisting of the hollow casing a' and the inking plug a² and the
wheel or wheels B. In the section Figure 2 the inking plug a² is in working
position having ink charged into its trough a³ by means of the charging device
Figure 4. This charging device consists of the glass part E with its point e¹ and
the rubber or flexible cap e2 the action of which is well known or the ink may be
charged into the trough as in any other manner. The trough ends with the
brush a which just touches the upper periphery of the wheel B and constantly
and automatically supplies ink thereto. The wheel B may be made in a variety of
ways as for instance as shown by Figure 6 where 3 discs with intermediate solid
bosses come together or Figure 7 with grooves cut into a solid circular disc or
From these
Figure 8 where plain discs are used with intermediate washers.
examples it will be clearly understood that a one line disc or two, three, or more
may be used as desired and they may be so turned that the broken lines will occur
opposite to each other or alternately or in any manner as desired and various
thicknesses and designs and sizes may be quickly exchanged to suit the drawing
in hand. The pen is handled just as an ordinary drawing ink pen.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improved drawing pen for making broken or dotted lines consisting of the
parts A a in combination with the inker a² and the wheel or wheels B substantially
such as herein set forth and as illustrated upon the accompanying drawings.
