PROVISIONAL SPECIFICATION.
An Improved Apparatus for Simultaneously Ruling Parallel Lines.
[WILLIAM ARTHUR SHAW, of Hyde Villas, Beechcroft Road, Upper Tooting,
in the County of Surrey, Student, do hereby declare the nature of this invention to
be as follows:-
The object of this invention is to produce an apparatus for simultaneously ruling
parallel lines such as the five lines used for musical staves, parallel lines for cash
columns, total lines for cclumns of figures, parallel lines for copy books, parallel lines
for block-cutters and die-sinkers, and all other purposes in which parallel lines are
required.
The invention consists of a frame carrying two rollers with loose horizontal axles
one above the other. The upper roller is covered with felt or other similarly.
absorbent material for the purpose of absorbing the ink necessary, which is put on in
any suitable manner.
The lower roller is provided with five or other number of projecting metal rails or
rings which slightly touch the circumference of the upper or ink roller, causing the'
same to rotate by the friction of the lower roller when rotated.
The metal rails or rings on the lower roller project below the frame carrying the
two rollers.
A suitable handle is provided, and the lines drawn by simply drawing the apparatus
over the paper or other material to be ruled, causing the lower roller to rotate on its
axle by the friction between the rings thereon and the paper; the rings taking off
the ink from the ink roller as they rotate.

COMPLETE SPECIFICATION.
An Improved Apparatus for Simultaneously Ruling Parallel Lines.
I WILLIAM ARTHUR SHAW of 3 Hyde Villas Beechcroft Road Upper Tooting
in the County of Surrey, Student 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 produce an apparatus for simultaneously ruling
parallel lines such as the five lines used for musical staves, parallel lines for cash
columns, total lines for columns of figures, parallel lines for copy books, parallel lines
for block cutters and die sinkers and all other purposes for which parallel lines are
required.
The invention consists of a frame carrying two rollers with horizontal axles one
above the other. The upper roller consists of felt or of wood covered with felt or
other similarly absorbent material for the purpose of absorbing the ink necessary,
which is put on in any suitable manner. The lower roller is provided with five or
any other number of projecting metal rails or rings which slightly touch the circum-
ference of the upper or ink roller causing the same to rotate by the friction of the
lower roller when rotated. The lower roller may consist of a solid roller on which
the required number of rings are produced by the incision of grooves; or of an axle
on which any number of loose rings may be slipped, the said loose rings being kept
at a proper distance apart from each other by means of smaller rings or washers also

page_text: slipped on to the axle, the whole contents of the axle being tightened up by a thumb
screw at one end of the said axle.
The said axle bearing the rings as aforesaid, can be inserted into the frame afore-
mentioned by springing the sides of the frame or by means of a slot or groove in the
frame aforesaid or in any other suitable manner.
The metal rails or rings on the lower roller project below the frame carrying the
two rollers.
A suitable handle is provided and the lines drawn by simply drawing the apparatus
over the paper or other material to be ruled the rings taking off the ink from the ink
roller as they rotate.
And in order that my invention may be fully understood and readily carried into
operation I will proceed to describe the accompanying sheet of drawings reference
being had to the figures and letters marked thereon.
Figure I is an elevation of the end of the apparatus.
Figure II is a transverse section.
Figure III is a section of the axle of the lower roller on which the rings A and
the washers B are slipped.
C. is a thumbscrew to tighten up the contents of the axle.
my
Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed I declare that what
said
I claim is
(1) The combination and arrangement of mechanism as and for the purpose herein
fully described.
(2) The mechanism hereintofore described with reference to Figure III of the accom-
panying drawing for rendering the rings on the lower roller moveable, thus enabling
any number of lines, any combination of lines, or lines of any distance apart to be
drawn.
In witness whereof I have hereunto set my hand and seal this Twelfth day of
September in the year of our Lord One thousand eight hundred and eighty
nine.
