page_text: LETTERS PATENT to John Smith Sworder, Civil Engineer, of Park Villas,
Loughton, in the County of Essex, for an Invention of "AN IMPROVED PRESS
OR MACHINE FOR PRODUCING COLOURED EMBOSSED IMPRESSIONS ON PAPER
PROVISIONAL SPECIFICATION left by the said John Smith Sworder at the
Office of the Commissioners of Patents on the 29th January 1881.
JOHN SMITH SWORDER, of Park Villas, Loughton, in the County of Essex.
"AN IMPROVED PRESS OR MACHINE FOR PRODUCING COLOURED EMBOSSED
IMPRESSIONS ON PAPER OR ANY OTHER MATERIAL FROM A DIE."
A vertical hand screw embossing press with plunger (A) carrying die (B),
unconnected with and arranged vertically underneath the screw (C), and lifted to
its highest position by a spring (D) or weight, and capable of vertical adjustment
at (E), the back part of the casting (F) or head of press being hollowed out to
receive a horizontal inking apparatus, consisting of a ducter (G), inking plate (H),
inking rollers (I), and roller carriage (J); a cam (K) fixed under the flywheel (L)
giving motion to the roller carriage through the medium of vibrating levers fixed
on a horizontal shaft (M); one of these levers (N) arranged horizontally carrying
a roller (O), kept in contact with the lower face of cam by a spring (P) or weight,
the other lever (Q) arranged vertically connected with the roller carriage, the
ducter and inking plate being made to partially revolve at each stroke of the press,
and the ducter, inking plate, and rollers, being arranged to readily disconnect.
The action of the press is as follows:-The first movement of the screw from its
highest position will cause the inking rollers to retire over the face of the die, the
plunger and die remaining stationary until the screw comes in contact with the
plunger; the motion of the screw being continued, the plunger and screw will
descend together to deliver the blow, the inking rollers retiring into the casting or
head of the press to receive a fresh supply of ink from the ducter.
I claim the general arrangement and action of parts combined in one hand
stainping press.

the said John Smith Sworder in the Great Seal Patent Office on the 28th July
1881.
JOHN SMITH SWORDER, of Park Villas, Loughton, in the County of Essex.
"AN IMPROVED PRESS OR MACHINE FOR PRODUCING COLOURED EMBOSSED
IMPRESSIONS ON PAPER OR ANY OTHER MATERIAL FROM A DIE."
A vertical hand screw embossing press constructed according to my Invention
is shown in its general features by the Figures on Sheet 1 of the annexed
Drawings.
Figure 1 is a side elevation; Figure 2 is a front elevation; Figure 3 is a section
on the line 1, 1, in Figure 1; and Figure 4 is a section on the line 2, 2, in
Figure 2.
The Figures on Sheet 2 of the Drawings show to a larger scale some details of
the machine as I prefer to have them. In some minute features they differ from
the Figures on Sheet 1.
The machine is provided with a plunger (A) carrying a die (B). This plunger is
unconnected with and arranged vertically underneath the screw (C), and it is
lifted to its highest position by a spring or springs (D) or a weight. The plunger
is capable of vertical adjustment at (E) to limit the height to which it shall rise.
The back part of the casting (F) or head of the press is hollowed out or fashioned
with a passage through it to receive and guide a horizontal inking apparatus.
The inking apparatus consists of several parts, a ductor, inking plate, inking rollers,
and a frame, in which the latter are carried. The ductor (G) is a roller mounted
in an ink trough affixed to the frame, and having a ratchet wheel upon its axis.
The inking plate (H) on which the ink is spread is arranged to rotate slowly upon
a vertical axis. The inking rollers (I) are carried in the frame or roller carriage (J).
A cam (K) fixed under the fly wheel (L) gives motion to the roller carriage through
the medium of vibrating levers fixed on a horizontal shaft (M); one of these
levers (N) arranged horizontally carries a roller (O), which is kept in contact with
the lower face of cam by a spring (P) or weight. The other lever (Q) is arranged
vertically, and is connected with the roller carriage by a link. The ductor and
inking plate are made to partially revolve at each stroke of the press by means of
a hinged finger or pawl (J') on the frame (J), which engages with the ratchet upon
the axis of the ductor roller. An endless cord passing around a pulley on the axis
of the ductor roller, and another pulley on the axis of the inking plate connects the
latter with the former, so that the inking plate also is caused slowly to rotate..
The ductor, inking plate, and rollers, are arranged to readily disconnect, and to be
capable of adjustment.
Figure 5 is a vertical section of the inking apparatus, and parts of the press in
the neighbourhood thereof.
Figure 6 is a plan, and Figure 7 is a side elevation of the frame or roller
carriage J.
Figures 8 are three views of the ductor G and the parts connected with the
supply of ink thereto.
Figure 9 shows in plan the arrangement for tightening the cord by which the
inking plate is rotated.
The action of the press is as follows:-
-
The first movement of the screw from its highest position will cause the inking
rollers to retire over the face of the die, the plunger and die remaining stationary
until the screw comes in contact with the plunger.
The motion of the screw being continued the plunger and screw will descend

page_text: together to deliver the blow, the inking rollers retiring into the casting or head of
the press; one of the rollers (I) then passes over the ductor roller, and receives a
fresh supply of ink from the ductor.
I claim the general arrangement and action of parts combined in one hand
stamping press.
In witness whereof, I, the said John Smith Sworder, have hereunto set my
hand and seal, this Twenty third day of July, in the year of our Lord
One thousand eight hundred and eighty one.
