Improvements in and connected with Machines for Scoring Cards
and similar Material.
We, JOHN GUMMER Stationers Assistant of Avenue Cottage Cranford near
Hounslow in the County of Middlesex and ROBERT OSBORN Stationers Assistant
of 69 Farleigh Road Stoke Newington N. in the County of Middlesex do hereby
declare the nature of this invention to be as follows:-
An appliance for scoring cards or similar material affixed to and working in
conjunction with a printing machine-lithographic or letterpress, by means of one
or more adjustable knives, either fixed or rotary-on a movable shaft or bar placed
on bearings at each side of machine so that the knives come in contact with the
sheet as the cylinder revolves, & scoring same, so that they can be easily and cleanly
folded.
We claim the novelty of this invention to be the process of scoring being
performed by and upon a printing machine during the process of printing by
means, of an appliance, so placed that the knives and cylinder work in combination.

COMPLETE SPECIFICATION.
Improvements in and connected with Machines for Scoring Cards
and similar Material.
We, JOHN GUMMER, of Western Villas, Bath Road, Hounslow late of Avenue
Cottage, Cranford, near Hounslow, in the County of Middlesex, Stationer's
Assistant and ROBERT OSBORN of 69 Farleigh Road, Stoke Newington, N., in
the County of Middlesex, Stationer's Assistant, 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:-
Our invention relates to machines for scoring cards or similar material in order
to facilitate the folding of the same and has for its object the provision of means
whereby the scoring is effected during the operation of printing upon the cards or
other material.
Our invention consists in the combination of a scoring device with the cylinder of
a printing machine-lithographic or letter-press.
This scoring device consists of one or more adjustable knives, which may be
either fixed or rotary; the whole being mounted upon the frame work of the
machine so that the knife or knives come in contact with the card or cards as the
cylinder revolves in the operation of printing, and scores them in order that they
may be easily and cleanly folded.
In order that our invention may be the better understood, we will now proceed
to describe one way in which our invention may be carried into effect, in relation
to the accompanying drawings, reference being had to the letters and figures marked
thereon.
Like letters refer to like parts in the figures.
Figure 1 is a side elevation of one form of our scoring device.
Figure 2 is a plan of the same.
Figure 3 is a perspective view showing our scoring device fitted upon a printing
machine the exlinder and fromine haine chowed only in nort

page_text: The form of scoring device we prefer to use, consists of a metal block A through
which is a square hole B, on the upper part of the block A a small arm C is
situated, to which is pivotably connected the lever D. At the other end of this
lever D, a circular rotary cutter E is pivotted and through a suitable hole in the
lever, a screw F passes which engages with a lug G upon the block A. Between
the head of the screw F and the lever D, a spiral spring H is arranged, so as to
press the lever in a downward direction, the amount of pressure being regulated by
the distance the screw F is screwed down or up as the case may be.
A set screw J is screwed in the lever D, so that its end rests upon the upper
surface of the block A in order to form an adjustable stop to prevent any further
downward movement of the lever D, than that desired, a lock nut K being provided
to lock the screw J in position, when any given position of it, is desired to be
definitely retained.
In Figure 3 we show how we use our device. The cylinder L of the printing
machine is supported as usual upon frames M and upon the frames we support a
square bar N so that it is disposed paralled to the axis of the cylinder L. Upon
this bar N we place the block A and clamp it thereto by the set screw O. We
may place any number of scoring devices upon the bar, as circumstances demand.
The operation of our device is as follows:-The set screw J is adjusted so that
the rotary cutter is within a very small distance of the cylinder, being close
enough to score any card or other material that is carried round by and upon the
cylinder in the path of the rotary cutter. The spring pressure is adjusted by the
screw F to be such as to force the cutter into the card, and should the cylinder
be uneven or not perfectly circular, the spring allows the lever to rise when
the cutter is passing over any prominence, but it cannot sink into the card
any deeper than it is desired or touch the cylinder by reason of the set screw J
forming a stop as herein-before described. The block or blocks A can be slid along
the bar N and adjusted at any point or points that may be desirable.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. A scoring device consisting of one or more adjustable cutters adapted to
work in conjunction with the cylinder of a printing machine substantially as and for
the purpose described.
2nd. In such a scoring device, an elastically pressed lever carrying a cutter and
an adjustable setting device substantially as and for the purposes described.
3rd. A scoring device constructed and arranged substantially as described and
illustrated in the accompanying drawings and for the purpose set forth.
