This Invention has for its object improvements in line dividers for dividing lines
of any length into any number of equal parts.
For this purpose we employ a sheet of paper or fabric on which are ruled a series
of lines so inclined towards one another and of such length that if two parallel lines be
drawn across them at suitable distance apart then each of these parallel lines shall
be divided into a number of equal parts the length of the divisions on one of the
parallels being twice the length of the divisions on the other.
Between the above parallels and parallel to them may be drawn a series of other
lines at equal or other distance apart.
In some cases in order to diminish the size of the paper a line may be drawn
dividing the space containing the converging lines between the two parallels above
described into two parts equal in distance from parallel to parallel, and the converging
lines on the one half so described may then be transposed or transferred on to the
other half thus forming two sets of inclining lines on the same fabric the divisions
made by one set on either of the parallel lines being two thirds the length of those
made by the other set on the same parallel.
The lines are numbered or they may be divided into sets of two three or more
and the end line of each set be numbered the spaces also between the lines in the
various sets may be tinted to different colors so that the lines of one set may
readily be distinguished from the lines of other sets or the lines themselves might
be of different colors.
The paper or fabric on which the lines are ruled or marked might be trans-
parent.
In this case in order to divide a line into any desired number of equal parts the
transparent fabric may be placed over the line keeping the parallel lines which are
marked upon it parallel with the line to be divided. The transparent paper is then
shifted up or down until the line to be divided has the requisite number of the
aloping lines passing across it.
The requisite number of divisions can then be pricked through on to the line or
marked upon it in other suitable manner.
A transparent paper or fabric having lines marked upon it as above described
may be attached at its ends to two rollers so that it may be wound from one to the

page_text: other always keeping the parallel lines on the fabric parallel with the rollers-
sufficient space may be left between the rollers to allow of part of the fabric where it
passes from one roller to the other being readily seen. This portion of the fabric
can be placed over the line to be divided and then by turning one or other of the
rollers the fabric can be made to travel in one or other direction until the requisite
number of the sloping lines cross the line to be divided-the points where they cross
can then be marked upon it by pricking through the transparent fabric or other-
wise.
Or in place of this arrangement the fabric passing from roller to roller may be
bent over a sharp straight edge which can be held parallel to the line to be
divided and the fabric be drawn over the edge in either direction desired by turning
one or other of the rollers,-or the fabric may be made up into an endless band
passing over a straight edge or over a pair of parallel straight edges at a distance
apart from one another and over a roller and similarly drawn to and fro over
the straight edge.
In the cases where a straight edge is employed it is unnecessary to mark the
series of the parallel lines on the fabric and the fabric need not be transparent as
the line which has to be divided has not to be seen through it.

We, ARTHUR GEORGE DAWSON of Park Mount, Macclesfield in the County of
Chester Manufacturer and FRANK EDWARD ADAMS of Cottage Lane Buxton
Road Macclesfield aforesaid Silk Designer do hereby declare the nature of our
invention for "IMPROVEMENTS IN LINE DIVIDERS FOR DIVIDING LINES OF ANY
LENGTH INTO ANY NUMBER OF EQUAL PARTS" and in what manner the same
is to be performed to be particularly described and ascertained in and by the 3
following statement:―
This Invention has for its object improvements in line dividers for dividing lines
of any length into any number of equal parts.
For this purpose we employ a sheet of paper or fabric on which is ruled a series
of lines so inclined towards one another and of such length that if two parallel lines
be drawn across them at suitable distance apart then each of these parallel lines shall
,be divided into a number of equal parts the length of the divisions on one of the
parallels being twice the length of the divisions on the other. One of these con-
verging lines may be drawn perpendicular to the parallel lines,

page_text: Between the above parallels and parallel to them may be drawn a series of other
lines at equal or other distance apart.
In some cases in order to diminish the size of the paper a line may be drawn
dividing the space containing the converging lines between the two parallels above
described into two parts equal in distance from parallel to parallel. The converging
lines on the one half so described may then be transposed or transferred on to the
other half in the manner shown in Figure 5 thus forming two sets of inclining lines
on the same fabric. The divisions made by one set on either of the containing
parallel lines being two-thirds the length of those made by the other set on the
same parallel.
The lines are numbered or they may be divided into sets of two three or more
and the end line of each set be numbered the spaces also between the lines in the
various sets may be tinted to different colors so that the lines of one set may
readily be distinguished from the lines of other sets-or the lines themselves might
be of different colors.
The paper or fabric on which the lines are ruled or marked might be trans-
parent.
In this case in order to divide a line into any desired number of equal parts the
transparent fabric may be placed over the line keeping the parallel lines which are
marked upon it parallel with the line to be divided. The transparent paper is then
shifted up or down until the line to be divided has the requisite number of the
sloping lines passing across it.
The requisite number of divisions can then be pricked through on to the line or
marked upon it in other suitable manner.
If the inclining lines above described are ruled upon some non transparent
substance, a transfer of paper or other suitable material may be employed, which
having the length of line to be divided marked upon it can be moved along the
lines in the manner above described until the requisite number of divisions being
found they can be ticked or marked on to the transfer and from there conveyed to
the line which has to be divided.
A sheet of paper or other fabric having the lines above described marked upon
it may for convenience be mounted on rollers like a map, or a transparent paper or
fabric having lines marked upon it as above described may be attached at its ends
to two rollers so that it may be wound from one to the other always keeping the
parallel lines on the fabric parallel with the rollers-sufficient space may be left
between the rollers to allow of part of the fabric where it passes from one roller to
the other being readily seen.
This portion of the fabric can be placed over the line to be divided and then by
turning one or other of the rollers the fabric can be made to travel in one or other
direction until the requisite number of the sloping lines cross the line to be divided
-the points where they cross can then be marked upon it by pricking through the
transparent fabric or otherwise.
Or in place of this arrangement the fabric passing from roller to roller may be
bent over a sharp straight edge which can be held parallel to the line to be
divided and the fabric be drawn over the edge in either direction desired by
turning one or other of the rollers or the fabric might be made up into an endless
band passing over a straight edge or over a pair of parallel straight edges at a
distance apart from one another and over a roller and similarly drawn to and fro
over the straight edge.
In the cases where a straight edge is employed it is unnecessary to mark the
series of the parallel lines on the fabric and the fabric need not be transparent as
the line which has to be divided has not to be seen through it.
In the Drawings,
Figure 1 shows the inclined lines cutting the two parallel lines in this case the
divisions on one parallel being in and on the other in.

The lines drawn between the two parallels are at unequal distances and are
drawn where the inclined lines mark upon them the simple fractions of an
inch ""&c.
The inclining lines are marked into sets by tinting certain spaces.
Figure 2 shows a method of marking into sets by dotting certain of the lines.
Figure 3 shows the perpendicular line in the middle of the inclined lines and the
sets marked by colouring certain of the lines.
Figure 4 shows two sets of inclined lines drawn similarly to Figures 1, 2 placed
side by side on the fabric for convenience the inclining lines on one set being
closer together than the inclining lines on the other set. In this case, the lines in
one set commencing at in apart and going on to 1 in apart and in the other set
commencing at in and going on to in apart. The intermediate parallel lines
being also similarly drawn to Figures 1 and 2.
Figure 5 shows the method of transferring one portion of the inclined lines on
to the other portion so that the parallels are divided into two sets of divisions one
set being two thirds the length of the other.
They are divided into sets of two or three by tinting certain spaces.
The intermediate parallel lines are drawn similarly to Figures 1 and 2.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
Our improvements in line dividere substantially as described.
