PROVISIONAL SPECIFICATION left by the said Samuel Cropper at the
Office of the Commissioners of Patents on the 27th October 1882.
SAMUEL CROPPER of Budge Row, Cannon Street in the City of London
IMPROVEMENTS IN APPARATUS EMPLOYED IN THE MANUFACTURE OF AND
PRINTING UPON BLANKS FOR BOXES MADE FROM PAPER, CARDBOARD AND OTHER
SIMILAR SHEET MATERIAL. Partly the result of a communication to me froin
abroad by Messieurs Cornell and Shelton of Birminghain in the State of Connecticut
and United States of America and partly my own invention.
The Invention has for its object improvements in apparatus employed in the
manufacture of and printing upon blanks for boxes made from paper, cardboard
and other similar sheet material and relates to that class of box which is produced
from blanks cut to the required outline and creased or embossed where the foldings
are required to be made.
Heretofore it has been proposed to cut out such blanks and produce the creases
or embossings simultaneously thereon by the aid of dies constructed of the necessary
lengths of "cutting rule" and the necessary lengths of embossing or blunt edge
"rule" arranged in the desired order and held in position in relation to each other
and in a frame or chase by means of metal or other furniture and wedges in a
similar manner to preparing a form for the printing press,

page_text: In the construction of cutting and embossing or creasing dies or forms in the
above described manner it is necessary to employ "furniture" of a great variety of
shapes and sizes to enable the various designs and sizes of dies to be produced
whilst a considerable amount of trouble is experienced in the production of such
description of dies or forms on account of the difficulty of obtaining furniture of
the exact sizes to produce the required distances between the pieces of cutting and
creasing or embossing rule.
Now according to the present Invention cutting and creasing or embossing dies
are readily and cheaply produced and when not required for use, can be stowed
away in their complete form ready for use when required, without locking up a
quantity of expensive metal or other furniture.
For this purpose a draft is first made on paper of the form of blank required
showing all the embossing lines and all the lines on which the paper is to be cut
through for the flaps, sides and other parts, then upon a well seasoned piece of
wood of the proper thickness and that will neither shrink nor crack the said draft
is placed and all the lines are marked through on to the-wood-so that the draft-or
pattern is seen on the wood, then by means of a jig or scroll saw the lines are all
" are
cut through the wood, the proper lengths and shapes of sharp "cutting rule
then placed in all the cuts in the wood corresponding with the cuts required in the
blanks and also the proper lengths of blunt edge rule are placed in all the cuts in
the wood corresponding with the creases or embossings required in the blanks..
The form thus produced is, when required for use, locked up in a chase, small
pieces of india rubber are fixed in the spaces between the pieces of rule to throw
off the blanks from the knives. In combination with the above described die or
cutter it is preferred to employ a counter die formed with a hard cutting-base and
embossing channels above such base so that the material is simultaneously cut upon
"some lines-and-creased-or-embossed upon other lines so that the material can be
readily bent to the desired shape.
.The Invention also relates to a. novel arrangement and combination of parts
whereby the cutting creasing or embossing and printing of the blanks are per-
formed at one operation by the aid of a single form constructed in the manner
above described or by the aid of a form in which the cutting and creasing or
embossing rule are held in position by ordinary "furniture" and wedges.
When employing a form constructed according to the plan forming the subject of
the first part of this invention, I cut out or otherwise form a space or spaces where
required to receive the type and I lock the latter in position by means of ordinary
furniture and wedges. When employing a form in which the rule for cutting and
creasing or embossing are held in position in a chase or frame by "furniture" and
wedges I set up the type in the required positions and lock the whole together by
furniture and wedges. A form constructed to perform the three operations
simultaneously as above described is fixed on the type bed of a printing machine
and in order that the inking rollers may not touch the cutting rule I cut away or
otherwise form the composition of such a length as to run between the cutting rule
on each side of the form and I fix on the type bed or on the edges of the form or
on any suitable portion of the machine on each side of the form a moveable and
adjustable bearer or runner which is so shaped as to lift the inking rollers over the
cutting rule at each end of the form and lower the said inking rollers on to
the type

SAMUEL CROPPER of Budge Row Cannon Street in the City of London
'IMPROVEMENTS IN APPARATUS EMPLOYED IN THE MANUFACTURE OF AND
PRINTING UPON BLANKS FOR BOXES MADE FROM PAPER CARDBOARD: AND OTHER.
SIMILAR SHEET MATERIAL" Partly the result of a communication to me from
abroad by Messieurs Cornell and.Shelton of Birmingham in the State of. Connecticut.
and United States of America and partly my own Invention.
The Invention has for its object improvements in apparatus employed in the
manufacture of and printing upon blanks for boxes made from paper cardboard'
and other similar sheet material and relates to that class of box which is produced
from blanks cut to the required outline and creased or embossed where the foldings.
are required to be made.
Figure 1 represents a blank for a paper box cut and creased or embossed as
above described a being the lines produced by cutting and b the creases or
embossings.
Heretofore it has been proposed to cut out such blanks and produce the creases
or embossings simultaneously thereon by the aid of dies constructed of the necessary
lengths of "cutting rule" and the necessary lengths of embossing or blunt edge
"rule" arranged in the desired order and held in position in relation to each
other and in a frame or chase by means of metal or other furniture and wedges in
a similar manner to preparing a form for the printing press.
In the construction of cutting and embossing or creasing dies or forms in the
above described manner it is necessary to employ "furniture" of a great variety of
shapes and sizes to enable the various designs and sizes of dies to be produced
whilst a considerable amount of trouble is experienced in the production of such
description of dies or forms on account of the difficulty of obtaining furniture of
the exact sizes to produce the required distances between the pieces of cutting and
creasing or embossing "rule."
Now according to the present Invention cutting and creasing or embossing dies
are readily and cheaply produced and when not required for use can be stowed
away in their complete form ready for use when required without locking up a
quantity of expensive metal or other furniture.
Figure 2 is a cross section, Figure 3 is an elevation or edge view and Figure 4 is
a plan of a cutting embossing and printing form or die and parts of machinery
constructed according to the present Invention.
For this purpose a draft is first made on paper of the form of blank required
showing all the embossing lines and all the lines on which the paper is to be cut
through for the flaps sides and other parts then upon a well seasoned piece of
wood c of the proper thickness and that will neither shrink nor crack the said
draft is placed and all the lines are marked through on to the wood so that the
draft or pattern is seen on the wood, then by means of a jig or scroll saw the lines
are all cut through the wood; the proper lengths and shapes of sharp "cutting
rule" are then placed in all the cuts in the wood corresponding with the cuts
required in the blanks and also the proper lengths of blunt-edge rule e are placed
in all the cuts in the wood corresponding with the creases or embossings required
in the blanks. The form thus produced is when required for use locked up in a
chase. Small pieces of india rubber fare fixed in the spaces between the pieces of
rule and also outside the die to throw off the blanks from the knives. In combi-
nation with the above described die or cutter it is preferred to employ a counter

page_text: die not shown but which is formed as is well understood with a hard cutting-base
and embossing channels above such base so that the material is simultaneously cut
upon some lines and creased or embossed upon other lines in order that the material
can be readily bent to the desired shape.
The Invention also relates to a novel arrangement and combination of parts
whereby the cutting creasing or embossing and printing of the blanks are per-
formed at one operation by the aid of a single forin constructed in the manner
above described or by the aid of a form in which the cutting and creasing or
embossing rulo are held in position by ordinary "furniture" and wedges.
When employing a form constructed according to the plan forming the subject
of the first part of this Invention I cut out or otherwise form a space or spaces g
where required to receive the type and 1 lock the latter in position by means of
ordinary furniture and wedges. When employing a form in which the cutting
rule d and creasing or embossing rule e are held in position in a chase or frame by
"furniture" and wedges I set up the type in the required positions and lock the
whole together by ordinary furniture and wedges.
A form constructed to perform the three operations simultaneously as above
described is fixed on the type bed of a printing machine and in order that the
inking rollers i may not touch the cutting rule I cut away or otherwise form the
composition of such a length as to run between the cutting rule d on each side of
the form and I fix on the type bed h or on-the edges-of-the form or on any suitable
portion of the machine on each side of the form a moveable and adjustable bearer
or runner which is so shaped as to lift the inking rollers over the cutting rulo d
at each end of the form and lower the said inking rollers i on to the type locked
up in the spaces g..
It will be readily understood that other forms of blanks for paper boxes can bo
produced according to-the-present-Invention and that the die or form may be fixed
in other position on the type bed and the printing can be variously arranged 'as
may be required and the bearers or runners will be shaped and adjusted as may
be required to lift tho inking rollers i over the cutting rule and lower them into
position to supply ink to the type.
Having thus described the nature of the said Invention and the mode in which
the samo can be carried into effect 1 would have it understood that what I
claim is
First The method of constructing a cutting and embossing die substantially as
herein shown and described and for the purpose stated.
Second The novel combination and construction of parts whereby the combined
processes of cutting embossing and printing blanks for paper boxes can be performed
at a single operation substantially as herein shown and described, and
Third The employment of bearers or runners, in machines for simultaneously
cutting out embossing and printing blanks for paper boxes, so that the inking
roller or rollers may be automatically raised clear of the cutting rule and
lowered into position to supply ink to the type substantially as herein shown and
described.
In witness whereof I the said Samuel Cropper have hereunto set my hand
and seal this Twenty fifth day of April in the year of our Lord One
