IMPROVEMENTS IN APPARATUS FOR EM
Year: 1866

page_text: LETTERS PATENT to John Ingram, of 3, Cleveland Villas, London Road,
Clapton, Stationer, and John Gough, of 66, King Street, Stepney,
Engineer, for the Invention of "IMPROVEMENTS IN APPARATUS FOR EM-
Sealed the 27th July 1866, and dated the 30th January 1866.
PROVISIONAL SPECIFICATION left by the said John Ingram and John
Gough at the Office of the Commissioners of Patents, with their Petition,
on the 30th January 1866.
We, JOHN INGRAM, of 3, Cleveland Villas, London Road, Clapton, Stationer,
and JOHN GOUGH, of 66, King Street, Stepney, Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR EM-
BOSSING IN COLOURS ON PAPER, ENVELOPES, OR OTHER ARTICLES," to be as follows:-
This Invention consists in an automatic method of coloring a die in an
ordinary embossing press while in motion, and thereby producing by expeditious
and economical means, and in a superior manner, what is known as
bossing in colours."
To the plunger of an ordinary screw press is attached a forked guide frame,
which embraces the sides of the press, and is free to rise and fall with the
plunger. This frame is parallel to the face of the die, and carries a second
guide frame free to move in it in a horizontal direction. To this second
guide frame is attached a roller case containing the requisite number of rollers
for completely distributing and applying the color. Motion is given to this

page_text: frame with roller case attached by a lever affixed to the body of the press, one
arm of which is connected with the plunger, the motion of which effects the
passage of the rollers over the distributing table and face of the die. By this
arrangement the time occupied by the rise and fall of the plunger is utilised by
the distribution and application of the color, and a more expeditious result
thereby obtained.
To effect the distribution and application of the color is affixed a table to
the under side of the frame first referred to, an opening in a certain portion of
which exposes the face of a color box placed above it, and having in its under
side an adjustable aperture effectually to control the quantity of color to be
applied, which is carried away and distributed by the rollers in the roller case
before referred to, and which are so arranged as to secure effectual and
perfect distribution.
The peculiar features of this Invention consist in the time occupied by the
motion of the plunger being utilised by the action of the coloring apparatus
and the self-acting and adjustable color supply by means of the color box
herein referred to, and which afford the following among other advantages,
cleanliness of working, great economy of color, and facility for working short
numbers (if necessary) without tedious delay in changing the die and color.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Ingram and John Gough in the Great Seal Patent
Office on the 28th July 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Jonn
INGRAM, of 8, Cleveland Villas, London Road, Clapton, Stationer, and JoHN
GOUGH, of 66, King Street, Stepney, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of January, in the year of our
Lord One thousand eight hundred and sixty-six, in the twenty-ninth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said John Ingram and John Gough, Her special license that we, the
said John Ingram and John Gough, our executors, administrators, and assigns,
or such others as we, the said John Ingram and John Gough, our executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time, and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and

page_text: Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR EMBOSSING
IN COLORS ON PAPER, ENVELOPES, OR OTHER ARTICLES," upon the condition
(amongst others) that we, the said John Ingram and John Gough, our execu-
tors or administrators, by an instrument in writing under our, or their, or one
of their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said John Ingram and John Gough, do
hereby declare the nature of our said 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 consists in an automatic method of coloring a die such as is
used in an ordinary embossing press while the die is in motion by employing
self-acting apparatus such as is herein-after described and shewn in the
Drawings annexed.
Fig. 1 is a side elevation of our improved apparatus; Fig. 2 is a front
elevation; Fig. 3 is a sectional plan on the line y ----z in Fig. 1; Fig. 4
is a plan, and Fig. 5 is a section of the color box F; Fig. 6 is a perspective
Drawing of the frames B and C, with the roller case E removed, and with the
distributing table D attached. The corresponding parts in cach Fig. are
indicated by the same letters.
A represents the body of an embossing press, which is constructed in the
ordinary manner. To the plunger (a) is attached the guide frame B, which
moves vertically with the plunger, the latter being raised by a helical spring
or other means. A second frame C is fitted to the frame B, and moves in it
horizontally, being moved by the action of the extending arm of the lever (e)
acted upon by the plunger. The die (6) is fixed into the plunger in the usual
manner. A distributing table D is attached under the frame B, and to the
frame C is affixed the roller case E carrying the coloring rollers; those used
by us are so arranged that a portion of them act obliquely, as shewn in Fig. 3.
We prefer to use several rollers of comparatively small diameter. At the end
of the distributing table D is an opening (d), into which fits the adjustable
color box F, so placed that when in use it is flush on the under surface. The
construction of the color box we use is shewn in plan and section in Figs. 4
and 5; it is fitted by preference with a hinged door (f) acted upon by a
thumbscrew, which completely controls tho quantity of color to be distributed
over the table; but other methods of regulating the supply of color may be

page_text: employed. The action of the press may be described generally as follows:-
When the press is in motion the roller at the back of the case E removes the
prescribed portion of color which is allowed to issue from the color box F.
This color is then evenly and thoroughly distributed over the table D by the
reversed oblique rollers next in place, as shewn in Fig. 3, and is applied by
the front rollers to the surface of the die. The plunger (a) in its descent
actuates the lever (c), and the frame C and roller case E are thus withdrawn,
and the plunger (a) with the colored die (b) allowed to descend upon the
surface required to be embossed, and the back roller is then again in position
to receive a new charge of color from the color box.
Having now described our self-acting apparatus, we would have it under-
stood that we do not limit ourselves to the precise details of the parts shewn,
as while the principle of action may be retained it may be carried out by
other equivalent means; nor do we claim the mechanical parts separately;
but what we claim is,-
1st, the combination of parts forming the self-acting coloring apparatus
constructed and applied as herein-before described.
2nd, the application of the adjustable and removeable supply apparatus F
in combination with the table D, as described.
3rd, the application of the moveable frames B and C in combination with
rollers arranged in the roller case E, substantially as described.
In witness whereof, we, the said John Ingram and John Gough, have
hereunto set our hands and seals, this Twenty-eighth day of July,
in the year of our Lord One thousand eight hundred and sixty-six.
