page_text: I, JOHN WOOD of 236 Wellington Road South, Stockport in the County of Chester,
Professor of Music do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct an improved metallic pen by means of
which two, three or more parellel lines can be drawn simultaneously and which is
specially applicable for ruling cash columns and for ruling the lines between which
the total is placed when a column of figures is added up.
The pen is constructed in the form of a domne (or some such similar shape) which
does duty as a holder, such holder having divisions or grooves into which the requisite
number of nibs may be placed, the aforesaid divisions or grooves, corresponding to the
curve of the respective nibs, which are to be inserted.
The back or heel of the pen which projects from the centre of dome, and forming
part of the holder may be constructed round, or barrel shaped; so as to fit on the end
of a stick, or may be and preferably is constructed to fit into any ordinary holder in
general use, exactly the same as a single slip pen.
Each nib is provided with a pin working lengthwise in a slit in the said holder,
forming part of a bayonet joint by means of which a nib can be raised when it is not
required to rule a line, so that the same pen can be used for different combinations of
lines.

page_text: I, JOHN WOOD of 236 Wellington Road South, Stockport in the County of Chester,
Professor of Music do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object of this invention is to construct an improved metallic pen by means of
which two, three, or more parallel lines can be drawn simultaneously, and which is
specially applicable for ruling cash columns and for ruling the lines between which
the total is placed when a column of figures is added up.
The pen is constructed in the form of a dome (or some such similar shape) which
does duty as a holder, such holder having divisions or grooves, into which the requisite
number of nibs may be placed, the aforesaid divisions or grooves corresponding to the
curve of the respective nibs which are to be inserted.
The back or heel of the pen which projects from the centre of the dome and forming
part of the holder may be constructed round or barrel shaped, so as to fit on the end
of a stick or may be and preferably is constructed to fit into any ordinary pen holder
in general use, exactly the same as a single slip pen. Each nib is provided with a pin
working lengthwise in a slit in the said holder, forming part of a bayonet joint by
means of which a nib can be raised when it is not required to rule a line so that the
same pen can be used for different combinations of lines.
And in order that my invention may be more fully understood and carried into
practice, I will now proceed to describe the same with reference to the accompanying
drawings in which similar letters indicate corresponding parts in all the figures.
Figure 1 shews the holder A with the aforesaid divisions or grooves a a the slits b¹
and constructed as a slip pen b. Figure 2 is a side view of Figure 1. Figure 3 shews
the same holder A with the aforesaid nibs inserted therein, placed in the shank c of an
ordinary pen holder ready for use, and with all the nibs drawn out in position for
ruling. Figure 4 shews the reverse side of figure 3 shewing the clips d d à bent over
the sides to the curve of each division or groove thus giving additional support to the
inserted nibs, and when any of the said nibs are not required to rule a line they can
be raised like the one shewn at e. Figure 5 shews an alternative to the clips d d d
shewn in Figure 4 consisting of eight narrow rims fff (embossed in or otherwise)
and placed at the sides of each division or groove. These rims are just sufficiently
raised as to bring them closely under the side edges of each inserted nib thus inclining
them to the inner grooves of the holder A and thereby keeping the points of the said
nibs upon a level with each other. Figure 5* which is a section on the line xx
Figure 5 shews the eight narrow rims fff. g is the heel part of the holder A con-
structed round or barrel shaped as a variation from the slip shewn in Figures 1 & 2.
This heel part g is fitted on to the end of a stick in the ordinary manner as shewn in
Figure 4. Figure 6 shews the four nibs separate from the holder A, each provided
with a pin h by means of which the nibs can be so arranged as to produce the different

page_text: combinations of lines shewn in Figure 7. The nib No. 4 (Fig. 6) has a coarser or
broader point which yields a line in proportionate contrast to the other three-The
holder A may be constructed without the clips d or the rims but it would add to the
firmness and accuracy of the pen when ruling to adopt either one or the other. The
slits in the holder A should be neither wider nor longer than is necessary to produce
the correct working of the nibs.
The drawings illustrate my invention as fitted with four nibs but I wish it to be
clearly understood that I do not confine myself to this or any other number.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
(1) The construction of a holder A with divisions or grooves a and slits 6¹ made
either as a slip or as a barrel pen substantially as and for the purpose hereinbefore set
forth and illustrated in Figures 1 to 5.
(2) The holder A constructed as described in claim 1 with side clips d or rims f
substantially as and for the purpose hereinbefore set forth and illustrated in Figures 4,
5 and 5.
(3) The construction of the two nibs 3 and 4 (Figure 6) for the purpose of ruling
parallel lines close together and also the pins (Figure 6) substantially as and for the
purpose hereinbefore set forth and illustrated in Figures 3, 4, 6 and 7.
Dated this 11th day of January 1889.
