Mrs. GRACE MARY MILNE 31 Heathfield Park Willesden Green London
County of Middlesex do hereby declare the nature of this invention to be as
follows:-
-
This machine is to be named the Rolograph. It consists of two rollers the one
placed on the top of the other and running conversely, they turn on screw spindles
or axles and these axles are let in to two brackets or side-pieces which hold the
rollers together the axles themselves being also held close and connected by elastic
bands. These bands being held tight press the one roller firmly on the top of the
other and also assist in making the rollers act as a clip, by stretching when the
rollers are lifted up the one from the other. These rollers can be fitted to any
ordinary desk or writing slab and are for the purpose of assisting to write and
rule evenly & easily etc. There is fixed on the axle of the under roller a wheel
with twelve or more or less teeth and which is about half the size of the circum-
ference of one of the rollers and fixed on to the bracket is a spring which fits into
the teeth of the wheel for the purpose of checking the revolving of the rollers so
as to give certain equal distances in the circumference of the rollers and for the
purpose of thereby enabling the writer to rule or mark at equi-distance papers
which may be passed through between them. On the top roller are placed several
layers of blotting-paper to dry the writing as the paper is passed through between
the rollers and as one layer is used it can so be pulled off to leave several other
distinct ones underneath; these rulers which can be made of any kind of paper
are also made and sold separate from this machine for the purpose of providing as
relays and as rulers to be used alone and they are made in different lengths &
diameters & with a greater circumference and also hollow in the centre as the case
may be. There is also a flat slab or desk which may or not be attached to the
rollers on both or all sides for the purpose of writing and ruling on, and this slab or
desk has several lines drawn across it for the purpose of writing & ruling evenly
and for keeping the same distance between each of the lines. Attached to the
left hand axle of the top roller is a small knife which works by turning the roller
round.

GRACE MARY MILNE 31 Heathfield Park, Willesden Green London, 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 named the Rolograph, consists of two rollers affixed to a desk
one on the top or above the other which run conversely and in contact so that by
placing the hand by the one roller both are turned. Drawing furnished herewith
to show the mode of working, viz., the cogged wheel C which is affixed to the lower
roller which rotates beneath the desk by means of an iron pin I serving to prevent
the roller turning back although the little ratchet R can be released if it is desired,
as the lower roller is not seen. A letter, as dotted lines L, when placed at the
lower edge of the upper roller is carried through without creasing on the principle

thus holding it in its place whereas for mechanical purposes lines can be drawn
parallel one to another. Two parallel lines S, there may be more if required, are
drawn or engraved on the slab of desk parallel to the axis of roller so that when
a letter is being written the lines show through keeping what is written equi
distant.
The side bracket B may be made of metal or wood being fixed to desk having a
slot at top and a hole punctured at the side. The two rollers have iron pins driven
in at each end forming the axis on which the roller is turned as at A & A'-the
top one falls in the slot, the under one passes through the side bracket, the rollers
are by this means held in their place and the india rubber band, as dotted line, D'
holds them together. These rollers may be sold separately as blotting pads being
covered with blotting paper which in itself is made on the principle of an Archi-
medean screw by which means the blotting paper can be put on to insure a level
surface and by which creasing is prevented. This is important because the paper
then is not pinched tighter in one place than another. The shape of blotting paper
is shown in drawing at T.
A pencil sharpener may be attached at left hand of the upper roller.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is the following features of novelty viz.,
1. A desk and ruler combination which not only holds paper firmly when writing,
but will admit of its being raised or lowered in the same horizontal position without
putting down the pen. Assisting people to write straight by means of the lines
printed or tooled on the desk.
2. A ruler by which lines can be ruled more parallel than any other by means of
the soft padded nature of the blotting paper & the particular form in which it is
cut and put on the roller.
3. A circular cutter affixed to the ruler for sharpening pencils.
