1 HENRY HARRIS LAKE of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
This invention relates to ruling apparatus and provides for the ruling in an easy
and almost automatic manner of parallel and equidistant lines.
This apparatus consists of two parts; a ruler and a cylinder united at their ends by
suitable connecting pieces nails or screws passing through each connecting piece
attaching them to the cylinder and ruler, and serving as axes whereon the said ruler
and cylinder can turn.
The apparatus may be made either of ivory, wood, metal or any other material
and the ruler may be of a square, flat or other form the operation thereof being the
same.
At one end of the ruler I attach a scale whereby the distance between each line to
be drawn is obtained; sometimes I place on this scale an index for more accurately
gauging the distance between the lines. When it is not required to use the rule the
scale is folded and passes under the rule.
When a sheet of paper is to be ruled by means of the apparatus, the rule is placed
parallel to the head of the sheet, a rotary motion is then imparted to the cylinder with
the left hand the ruler follows the cylinder and when stopped is always parallel with
the head of the paper or the last line drawn as the case may be.
The divisions on the scale serve to measure the distance between every line, it is
therefore evident that with this apparatus lines of any required distance apart can be
made.

1, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex 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
This invention relates to apparatus for ruling lines and has for its object the ruling 5
in an easy and almost automatic manner of parallel and equidistant lines.
The apparatus is illustrated in the accompanying drawings in which Figure 1 is a
plan of the said apparatus.
Figure 2 is an end view and
Figure 3 a cross section of the same.
This apparatus comprises two parts; a ruler A and a cylinder B; these two parts
are united at their ends by suitable connecting pieces a, a and nails or screws passing
through each connecting piece for attaching them to the cylinder, and ruler, and
serving as axes whereon the said ruler and cylinder can turn.
At or near one end of the ruler A is attached a small scale b provided with
divisions whereby the distance between each line to be drawn is obtained. I some-
times place upon this graduated scale an index for more accurately gauging the
distance between the lines.
When it is not required to use the rule the small scale bis folded and passes under
the rule A.
When a sheet of paper is to be ruled by means of the apparatus, the rule A is
placed parallel to the head of the sheet a rotary motion is then imparted to the
cylinder B with the left hand, the rule A follows the cylinder B and is always parallel
with the head of the paper or the last line drawn, as the case may be.
The divisions on the scale serve to measure the distance between every line, it is
therefore evident that with this apparatus lines of any required distance apart can be
made. The apparatus may be of wood, ivory, metal or any other suitable material,
and of any convenient form other than that shown in the drawing.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
The improved ruler constructed and combined substantially as described with
reference to the drawings, for the purpose specified.
