Year: 1867

page_text: LETTERS PATENT to John Gough, of 42, Kirby Street, Hatton Garden,
in the County of Middlesex, Engineer, for the Invention of "IMPROVE
MENTS IN ARMING PRESSES FOR PRODUCING DEVICES IN THE COVERS OF BOOKS
AND OTHER ARTICLES."
Sealed the 15th November 1867, and dated the 21st May 1867.
PROVISIONAL SPECIFICATION left by the said John Gough at the Office
of the Commissioners of Patents, with his Petition, on the 21st May
1867.
I, JOHN GOUGH, of 42, Kirby Street, Hatton Garden, in the County of
Middlesex, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN ARMING PRESSES FOR PRODUCING DEVICES ON THE COVERS OF
BOOKS AND OTHER ARTICLES," to be as follows:-
My said Invention consists, first, of improvements in the gauges employed
for the correct adjustment of the book cover or other article to be impressed
underneath the die plate. To these gauges I attach springs which rise above
the level of their upper surface, and serve to prevent the edge of the book
cover or other article from being pushed over the gauge, but which are
flattened down on the gauge by the die plate when the impression is being
given.
My second improvement relates to the mechanism employed to force
down the die plate on the substance to be impressed, the table which supports
the said substance being a fixture. Above the heater box (to the under side

page_text: of which the die plate is attached) and underneath the head frame of the
machine a shaft is mounted in suitable bearings free to revolve therein; to
this shaft a continuous rotatory motion is imparted by suitable geering. I
form an eccentric on this shaft, and supports the shaft immediately on each
side of it by extra bearings formed in the head frame of the machine; this
eccentric is made to bear against the circumference of a friction roller
mounted in suitable bearings on the upper side of the said heater box, as
the shaft revolves the eccentric depresses the box together with the die plate;
balance weights are employed to raise the box again. When it is thought
desirable to give two impressions for one revolution of the said shaft I
substitute a double-acting cam for the eccentric, which cam as the shaft
revolves serves to depress the said box and die plate once for each half turn
of the shaft. When it is thought desirable to make the said heater box
together with the die plate a fixture, and to force up the table against the
die plate, I place the said shaft and the mechanism connected with it under-
neath the table which is then made free to rise and fall.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Gough in the Great Seal Patent Office on the 20th
November 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GOUGH, of 42, Kirby Street, Hatton Garden, in the County of Middlesex,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of May, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Gough, Her special licence that I, the said John Gough, my executors,
administrators, and assigns, or such others as I, the said John Gough, my
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
Isle of Man, an Invention for "IMPROVEMENTS IN ARMING PRESSES FOR PRO-
DUCING DEVICES ON THE COVERS OF BOOKS AND OTHER ARTICLES," upon the
condition (amongst others) that I, the said John Gough, my executors or
administrators, by an instrument in writing under my, or their, or one of their

page_text: 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 1, the said John Gough, do hereby declare the
nature of my said Invention, and in what manuer the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment, that is to say:-
My said Invention consists, first, of improvements in the guages employed
for the correct adjustment of the book cover or other article to be impressed
underneath the die plate. To these gauges I attach springs which rise above
the level of their upper surface, and serve to prevent the edge of the book
cover or other article from being pushed over the gauge, but which are
flattened down on the gauge by the die plate when the impression is being
given.
My second improvement relates to the mechanism employed to force down
the die plate on the substance to be impressed, the table which supports the
said substance being a fixture. Above the heater box (to the under side of
which the die plate is attached) and underneath the head frame of the
machine a shaft is mounted in suitable bearings free to revolve therein; to
this shaft a continuous rotatory motion is imparted by suitable gearing. I
form an excentric on this shaft, and support the shaft immediately on each
side of it by extra bearings formed in the head frame of the machine; this
excentric is made to bear against the circumference of a friction roller
mounted in suitable bearings on the upper side of the said heater box ; as the
shaft revolves the excentric depresses the box together with the die plate;
balance weights are employed to raise the box again. When it is thought
desirable to give two impressions for one revolution of the said shaft I
substitute a double-acting cam for the excentric, which cam as the shaft
revolves serves to depress the said box and die plate once for each half turn of
the shaft. When it is thought desirable to make the said heater box
together with the die plate a fixture, and to force up the table against the
die plate, I place the above-described shaft and the mechanism connected
with it underneath the table, which is then made free to rise and fall.
And in order that my said Invention may be most fully understood and
readily carried into effect I will proceed to describe the Drawings hereunto
annexed.
In the accompanying Sheet of Drawings, Figs. 1 and 2 represent
different views of an arming press embodying my improvements, and Figs.

page_text: 8 to 8 details of the same. Similar letters of reference point to corresponding
parts in all the views.
These presses consist principally of the table for giving support to the
book cover or other article to be impressed; the gauges for adjusting the
said article on the table so as to set it correctly underneath the die plate;
the die plate and the box for heating it to which it is attached; the
mechanism by means of which the die plate is forced down on the article to
be impressed; or the table together with the article is forced up against the
die plate (according to the position which the said mechanism occupies in the
press); lastly, the gearing for the transmission and control of the motive power
employed in actuating the press.
a represents the impression table on which the article is placed; it is made
adjustable as to height by means of the wedge b, which is regulated by the
screw c; this wedge rests on the lower portion of the table a. The table is
free to separate vertically as it is acted on by the wedge, but is prevented
from lateral motion by the corresponding guides d, d, formed on each. The
table a is also capable of a lateral motion along the guides e, e, regulated by
the screw shown at f. 9, 9, represents the gauges for adjusting the article on
the table a correctly underneath the die plate; they consist of a thin piece of
metal furnished on the upper surface with a series of springs h, h, and with
the binding screws i, i, to fix them in their required position. , represents the
heater box, to the under surface of which the die plate l is attached, the said
box is usually kept hot by means of gas jets kept burning in its interior.
The said heater box is attached to the frame m, which is formed with guides
n, n, which slide on the columns o, o, by which the head frame P is united
to the lower frame q of the press.
The mechanism employed in producing the pressure consists of the excentric r
formed on the shaft s, which shaft is free to revolve in the bearings t, t, in
the head frame p, and is further supported by the extra bearings u, u, ono
immediately on each side of it. This excentric is made to bear against the
circumference of a friction roller v, the spindle w of which is free to turn in
suitable bearings x, x, on the upper side of the sliding frame m. The
balance weights y, y, through the medium of the levers,, and the links
a', a raise the said sliding frame m together with the heater box k and die
plate after the impression has been given. The power is applied to the
press through a belt to the pulleys b', b, at one extremity of the shaft c'
which is carried in bearings d', d'; in the head frame p of the press a pinion
marked e¹ fast on this shaft gears into the tooth wheel f¹ fast on one extremity
of the excentric shaft S. 9¹ represents, a tooth wheel fast on the opposite

page_text: extremity of the shaft c¹, which gears into the pinion h¹ loose on the stud i
fixed in the head frame p; this pinion is connected with the fly wheel ¹ (also
loose on the stud ) and drives it. A brake is fitted to the circumference
of the said fly wheel for the purpose of stopping the press readily; it is
attached to the vertical bar m¹, the upper end of which is supported by the
extremity of the stud on which the fly wheel is mounted, while its lower
extremity engages the hand lever n', the fulcrum of which is fixed in the
lower frame of the press at o. The belt is shifted on the pulleys h¹, h',
through the medium of the treadle lever p¹, the link q', the lever, the
link a', the bell crank t', and the sliding bar u¹.
Figs. 4 and 5 represent a modification of the mechanism for producing
the pressure, here the short excentric rod v¹ and strap ware substituted for
the friction roller v and the balance weights y, y.
Figs. 3 and 4 represent views of the arrangement where two impressions
for one revolution of the shaft s are required, the double-acting cam a¹ here
taking the place of the excentric as it revolves, twice producing an
impression for one revolution of the shaft s. When I prefer to maintain the
die plate a fixture, and to force up the impression table against it, I place the
same mechanism underneath the table, and as the same parts are employed,
their position in the press only being changed, I have not thought it necessary
to give separate views of the arrangement.
The mode of operation is as follows:-The table a having been previously
adjusted as to height to suit the thickness of the article to be impressed, and
the gauges g, g, adjusted to suit its length and breadth, the article is placed
on the table and pushed up against the gauges 9, 9, the springs h, h,
preventing its being pushed over them; as the excentric r revolves it forces
down the die plate or forces up the table against the die plate, according as
either arrangement of this part of my Invention is employed, and as it
continues to revolve the balance weights y, y, raise the die plate off the
article and allow of its removal and the substitution of another; or where the
table is forced up against the plate its own weight causes its descent and the
consequent separation of the parts.
Having thus described the nature of my Invention, and the manner of
5 performing the same, I would have it understood that I do not confine
myself to the exact details described; but what I claim is, the applica-
tion of the springs to the adjusting gauges as described. Also the
placing the shaft, furnished with the excentric or double-acting cam, either

page_text: between the heater box and the head frame of the press, or underneath
the table and between it and the lower frame of the press, and the
causing the said excentric or double-acting cam directly to produce the
required pressure by acting on the circumference of a friction roller, or against
the excentric rod, either being supported in bearings directly over the heater
box in the one arrangement or under the impression table in the other.
In witness whereof, I, the said John Gough, have hereunto set my
hand and seal, this Twentieth day of November, in the year of our
Lord One thousand eight hundred and sixty-seven.
JOHN GOUGH. (L.S.)
