An Improvement in or connected with Double Side Ruling Machines.
I, FREDERICK WILLIAM VICKERY, of 14, Newcastle Street, Farringdon Street,
London, Ruling Machine Maker, do hereby declare the nature of this invention
to be as follows:-
This invention has for object, ruling the unruled side of a sheet of paper or
material by a second set of ruling discs arranged a short distance from the first
ruling discs on a roller or bar under a second blanket, against the under face of
which the sheet is carried by the conveyor cords, the particular part where the
second ruling takes place having a roller to resist the up-thrust of the discs and
to ensure the line ruling being perfect.
The double side ruling machine by this invention is rendered very compact,
with less vibration, occupies very little room, ensures line ruling to perfection,
and if it has a top forward delivery by a separate set of conveyor cords from the
second blanket back roller, one attendant only will be required.
The shortness of the conveyor cords and that of the blankets prevent draughts
of air from windows and doors having effect upon the paper such as is found so
injurious with the usual long double side ruling machines in which the paper has
to be turned over for the second ruling from the top.

An ímprovėment in or connected with Double Side Ruling Machines,
I, FREDERICK WILLIAM VICKERY, of 14, Newcastle Street, Farringdon Street,
London, Ruling Machine Maker, 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 has for object, ruling the unruled side of a sheet of paper or
material by a second set of ruling discs arranged a short distance from the first
ruling discs on a roller or bar under a second blanket, against the under face of
which the sheet is carried by the conveyor cords, the particular part where the
second ruling takes place having a roller to resist the up-thrust of the discs and
to ensure the line ruling being perfect.

page_text: The double side ruling machine by this invention is rendered very compact,
with less vibration, it occupies very little room, ensures line ruling to perfection,
and by having a top forward delivery by a separate set of conveyor cords from
the second blanket back roller, one attendant only will be required.
The shortness of the conveyor cords and that of the blankets prevent draughts
of air from windows and doors having effect upon the paper, such as is found so
injurious with the usual long double side ruling machines in which the paper has
to be turned over for the second ruling from the top.
My invention is represented on the annexed sheet of drawings.
Figure 1, side elevation.

Figure 2, plan through line x, x.
A, frame composed of uprights and connecting beams. B, feed table. C,
taking off or delivery board. D, E, main rolls, between which the sheets of
paper to be ruled are placed by hand.
In contact with the roll I and guide rollers F, F, is an endless blanket or
canvas G. In addition to this endless blanket or canvas G, the roll D carries
and gives motion to endless cords H which bear on the blanket or canvas G and
pass round guide rollers I, I, I, and a tension roller J, as indicated by the
arrows for the first ruling of the sheets of paper. The roll E, guide roller K
and tension roller L have another series of endless cords M as top cords to bear
on the paper and keep it flat while passing to and from the first inking discs N
which are plain circular pieces of metal threaded on a rod P, and held at the
proper distances apart by intervening washers, or short lengths of tubing of
smaller diameter also on the rod P. The inking discs N run in contact with a
rubber roller Q on which the dropping edge of a strip of absorbent material
lays, this otherwise dipping in a trough R of colour from which the ink or colour
is supplied by capillary action in the well known manner.
The trough R is adjustable as to height in end uprights by the screws S to
regulate the supply of colour, the rod P with the discs bearing by their own
weight on the paper by the ends of it being free in the forks of the uprights.
T, is a roller directly under the discs to resist downward pressure and to keep
the paper perfectly flat while being ruled. U, is a balanced plate with raised
lips U which preserve the regular parallel travel of the blanket or canvas G
and at the same time keep it in tension.
The paper after leaving the first set of ruling discs N, and still between the
blanket cords H and held down by the cords M, moves along on the cords H,
the upper cords M being somewhat raised to free the paper from contact with
them, so that it moves along on the cords H only until it arrives under the second
endless blanket or canvas V, which for this purpose is above the paper and forms
the resisting surface while the second ruling is being effected on the underside
of the paper by the discs W mounted in a similar manner on the rod X and fed
with colour in a similar manner as the first set of discs N and whereby the
reverse side of the paper is me ruled in the desired manner either corresponding
with the first ruling or otherwise, both sides being ruled in the same machine
and without the paper being turned over as is usually done with double side
ruling machines.
The endless blanket or canvas V of the second ruling method is carried by
guide rollers Y and is kept in tension by the adjustable screw appliances Z.
Said blanket or canvas V only passes round the roller a and then upwardly, one
ply going over the roller b, and the other ply over the roller c, then both plies
run back downwardly round the roller Y and travel as indicated by the arrows.
It is round this back roller Y that the cord H from the first named blanket or
canvas G passes, so that the sheets of paper after the second ruling are carried
upwardly towards the front of the machine until they in succession arrive at
the fingers d up which the sides of the paper rise in order that an additional
stiffness may be given to the paper while being pushed forward by the blanket
or canvas V over above the receiving or delivery board C, the blanket or canvas

page_text: in conjunction with the cords H retaining their hold on the paper between them
until it is finally discharged.
The receiving board C at the delivery end has side cheeks e, e, and a stop or
check board f, all of which are adjustable to suit different sizes of paper sheets
that have to be ruled.
All the cords rollers are provided with annular channels along their length
and somewhat close together for reception of the cords, which channels also serve
for the adjustment and ensure the correct travel of the cords to carry or guide the
paper in a parallel manner through the machine.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
In a double side paper ruling machine, the combination of two separate endless
blankets or canvas bands G, V, one for receiving, in conjunction with cords H,
the sheets of paper to be ruled, and conveying them under the ruling discs N,
thence along to the point from which point the cords H alone carry the paper
to the second blanket or canvas V which bears on the paper only while the
second ruling on the reverse side of the paper is effected, the paper thus ruled on
both sides being conveyed by the cords H to the roller Y, and thence up between
the second blanket or canvas V, and the cords H to the delivery end of the
machine, where the sides of the paper ride over fingers d which cause the side
edges of the paper to rise and bellying the centre and thus give additional stiff-
ness to the paper for ensuring the final delivery in a flat even condition without
risks of the ruled lines sincaring or becoming blurred.
