Improvements in Disc Ruling Machines.
I, JOHN SHAW of Honley near Huddersfield in the County of York, 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 relates to what are known to the trade as disc ruling machines.
Hitherto in these machines when it has been required to adjust the position of
the lines to be ruled it has been necessary to loosen or unscrew the set screws which
secure the collars for holding the spaces and dises in position upon the shaft and
then move the discs and spaces to the position required.
In this arrangement a considerable amount of time and trouble is necessary, and
it is difficult to arrange an accurate adjustment; and also in ordinary dise ruling
machines the ink roller is arranged to bear on the discs with its own weight only,
whereby the necessary pressure for the required supply of ink is not always
attainable; the objects therefore of my present invention are, one, to combine with
the shaft which carries the discs certain mechanism whereby the adjustment of the
discs may be easily and accurately performed without it being necessary to unloosen
the collars or move the discs on the shaft, and-two-to combine with the ink
roller certain mechanism whereby its pressure upon the discs can be easily regulated
as desired.
In the attainment of object-one-aforesaid I arrange a shaft above the shaft
which carries the discs and connect the discs' shaft thereto by means of toggle
carriers which have movable covers to their bearings in order to facilitate the
removal of the discs' shaft when required.
Each end of the discs shaft bears in a radial slot or bearing formed in adjustable
brackets which are carried upon slides fitted to each side frame of the ruling
machine, and one said slide is formed with a bearing within which is carried the
journal of a double collared screw which is arranged with a thumb and finger head
in order to easily turn it. The upper shaft is also carried upon the adjustable
brackets aforesaid and has fixed thereto a lever or handle which is bent downwards
and carries at its lower end a screw with head and adjustable stop nut and the
lower end of said screw bears upon a plate which is fastened to the frame of
machine and upon said plate is pivotted a small lever or stop. By screwing the
said screw further through the lower end of the bent handle the upper shaft is
turned and the toggle carriers lift up the disc shaft by which means it will be
obvious that the vertical position of the discs are adjusted.
It will also be obvious that by lifting the bent lever or handle the upper shaft
with toggle carriers pull up the discs shaft within the radial bearings by which
means the discs are removed from their work and the ruling process upon the paper
or other material ceases.
The small lever or stop may then be moved round and the lower end of adjustable
screw rest thereon during the time the lateral position of the discs are being adjusted
accurately by turning the thumb and finger head of the screw which moves the
adjustable brackets upon the slides.
In order to attain object-two-aforesaid I carry the ink roller in adjustable
bearings which work in recesses or pockets formed in the adjustable brackets and
are moved as required by means of screws bearing in lugs also formed on said
brackets.
My invention will be more clearly understood by reference to the accompanying
drawings in which

Fig. 3 a cross sectional elevation taken on line a a and looking towards the right

Fig. 4 a cross sectional elevation taken on line b b and looking towards the right
of Fig. 1,
and
Fig. 5 is a side elevation of the lever or handle I employ for lifting up the discs
shaft.
Similar letters of reference denote corresponding parts in each view.
I arrange a shaft C above the ordinary shaft D which carries the ruling discs E,
and I connect the said discs shaft D thereto by means of toggle carriers F; which
are arranged with hinged or movable covers to their lower bearings in order to
facilitate the removal of the discs shaft, D when required and the said covers may
be kept in position when closed by the pivotted stops f².
Each end of the discs shaft D bears in a radial slot d¹ (see Fig. 3) or bearing.
formed in adjustable brackets G, one or both such slots having a movable cover g³
arranged in order to allow the discs shaft, D to be easily removed when required.
The adjustable brackets G are carried upon slides H which are secured to each.
side of the ruling machine frame T, and the right hand slide His formed with a
bearing within which is carried the journal of a double collared, screw K.
which is arranged with a thumb and finger head in order that it may be easily
turned.
The upper shaft C is also carried upon the adjustable brackets G and has fixed
thereto a lever or handle J which is bent downwards and has at its lower end j¹, an
adjustable screw and nut ', the lower end of said, screw bearing upon a plate M
whereby the vertical position of the discs shaft is secured in manner hereinbefore
described, and upon the said plate M is pivotted a small lever or stop m¹.
The machine is arranged with the ordinary ink trough O, which is carried upon
the adjustable brackets G.
The usual ink roller P is carried in adjustable bearings Q, which are supported
in recesses or pockets q' formed in the, adjustable brackets G and are moved as
required by means of screws S which bear in lugs formed on said brackets G..
The usual cloth wo conducts the ink from the trough O to the ink roller Q.
It will be obvious that by lifting the bent lever or handle J the upper shaft C
with toggle carriers F pulls up the discs' shaft D within the radial bearings d', by
which means the discs are removed from their work and the ruling process upon
the paper or other material X ceases.
The small lever or stop m¹ may then be moved round and the lower end of
adjustable screw rest thereon during the time the lateral position of the discs E
are being adjusted accurately by turning the thumb and finger head of the screw K
which moves the adjustable brackets G upon the slides H.
By turning the screws S one way or the other the required amount of pressure
of the ink roller Q upon the discs E is secured as will be well understood.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner, the same is to be performed. I declare that what I
claim is.
1. In disc ruling machines the combination with a discs' shaft D of a carrier
shaft C, toggle carriers F, adjustable brackets G, slides H and handle J,
substantially as described and for the attainment of the object specified.
2. In disc ruling machines the combination with an ink roller P of adjustable
bearings substantially as described and used for the purpose specified.
