"AN IMPROVED TYPOGRAPHIC PRESS."
This Invention relates to improvements in the construction of treadle printing-
presses, and will be of great service in printing books or similar work, also for
fancy printing, and for printing engravings. This result has not hitherto been
obtainable with a treadle printing press; moreover this machine will enable even a
lad of 12 years of age, and of average strength, to print from 1400 to 1600 sheets
of foolscap size per hour, whilst presses of similar size, but of ordinary construction,
require an attendant for turning the wheel and another for laying, and will,
nevertheless, not accomplish as much work.
The following points chiefly distinguish the press constructed according to my
Invention from ordinary presses, that is to say:-The bed or travelling table on
which the type is placed runs upon eight rollers turning on their axes; the to
and fro movement of the feed board is effected on slides by means of an excentric
guided by two connecting rods, and the feed-board delivers the sheet to the pincers
or nippers; the cylinder carries the sheet forward on the lower side so as to shorten
the space required for the machine; an excentric gear, connecting rod, catch, and
rachet actuate the inking cylinder; an automatically acting receiver formed of
laths or strips receives the sheet and places it upon the table, and a pointer
underneath the feed-board ensures the proper registering of the sheets in relaying
the same.
This press comprises the following the parts:-
A treadle, which by a rod is connected with the main-crank carrying a toothed
driving wheel; the said driving wheel, which takes into a suitable cog wheel, to
which is attached a connecting rod which by means of suitable guides actuates the
bed carrying the type which runs on suitable rollers, as herein before mentioned.
On a suitable shaft are mounted the excentrics, one of which actuates the cylinder
and the fork for stopping the same; another excentric mounted on this shaft
guides by suitable connecting rods the pincers, which are closed by another
excentric.
On the aforesaid excentric-shaft the excentric which imparts motion to the
feed board by suitable connecting rods is also mounted. The said feed-board is placed
in a convenient position for properly feeding the sheets to be printed to the
cylinder, suitable guides being provided for the same.

page_text: The inking mechanism is mounted on that side of the press which is opposite to
the sheet feeding table, but is likewise driven by an excentric mounted on the
general excentric shaft and a connecting rod in conjunction therewith. To this
connecting rod is hinged a lever or arm which actuates the ink-supplying device
and inking cylinder, the latter being provided with a crank and pawl gearing with
a ratchet wheel concentric to the said cylinder.
Above the inking mechanism the receiving table is placed. The receiving
apparatus or mechanism is driven from the excentric shaft by a rod, one end of
which forms a rack and gears with the toothed wheel which actuates the receiving
mechanism.
The sheets are delivered by suitable gearing, and passing over rollers are
conducted by cords or bands while travelling between the cylinder and the delivery
mechanism; the said cords or bands are stretched by suitable pulleys or rollers.
The cylinder of the press has a toothed ring on one side, which ring gears with a rack
at the side of the type-table from which it receives its motion. The machine is
also provided with a suitable fly wheel. The whole of the parts above described
are mounted on a suitable frame, substantially consisting of four or any requisite
number of legs, suitable bed plates, and the like, the whole being strengthened
by tie bars, as may be required.
