JOSEPH RICHMOND and WALTER WHITING, both of Kirby Street, Hatton Garden,
in the County of Middlesex, Engineers. *IMPROVEMENTS IN MACHINES FOR
EMBOSSING AND PRINTING THE COVERS OF BOOKS AND OTHER ARTICLES."
Our Invention has for its object the construction of machines commonly called
arming presses" in such a manner as to effect the following improvements therein,
that is to say, the production of the requisite pressure with less expenditure of
power, an increase of speed in working, the more effectual maintenance of the
parallelism of the table on which the book cover is placed with the face of the die,
increased facility for adjusting the cover or article on the table, and the more
effectual inking of the face of the die.
And our Invention consists in the combination of parts herein-after described as
constituting our improved machine.
The framework of the machine consists principally of two side frames or standards,
a head and base, which are firmly united together. The two side frames or
standards are united in the centre of the machine, so as to form a vertical rect-
angular opening which forms a deep guide for the moveable bed of the machine,
which bed supports on its upper surface the table on which the book cover is laid,
and also the inking apparatus. This moveable bed so guided receives at the proper
intervals an upward movement from below caused by the straightening of a pair of
jointed arms, the lower extremity of one of which arms abuts on the before-named
base. These jointed arms are worked by a cam, which through the intervention of
a connecting rod alternately straightens and bends the joint, and thereby raises or
lowers the bed. The said cam is fixed on the main shaft, which is suitably mounted
at the back of the machine. On this shaft is a spur wheel which receives motion
from a pinion shaft mounted above the main shaft; to this pinion shaft the power
is applied. On the upper surface of the bed is the table which receives the book
cover, this table is capable of a to-and-fro motion from the centre of the machine
outwards to the front thereof. This motion is imparted to the table at the required
intervals by a cam, also on the main shaft of the machine, through the intervention
of a connecting rod and levers. The die is attached in the usual manner to the
under surface of a heater box, which is fixed to the under side of the head of the
press. The rising of the bed underneath the table forces it, together with the book

page_text: cover resting thereon, upwards against the die, and thereby the cover is caused to
receive the impression from the die. On the sinking of the bed the table is passed
outwards to the front of the machine, where the impressed cover is removed and a
fresh one substituted.
As soon as the table passes from underneath the die a carriage carrying inking 5
rollers is rolled across the bed and back, inking the die as it passes under it both
ways. These inking rollers are supplied with ink from the surface of two ink
tables, one of which is placed on each side of the bed, face uppermost. The
direction of motion of the said carriage is at right angles to that of the table, and
the motion is given at the required intervals by a cam, also on the main shaft, 1
through the intervention of a connecting rod, bevil gearing (to change the direction),
levers and rods.
