(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
WILLIAM WAHLER, of No. 22, Myddleton Street, Clerkenwell,
Middlesex, Lithographic Printer, do hereby declare the nature of the
said Invention for "LITHOGRAPHIC PRINTING, BEING A SELF-ACTING LITHO-
GRAPHIC PRINTING MACHINE, TO BE PROPELLED BY HAND, STEAM, OR OTHER
MOTIVE POWER," to be as follows (reference being had to the three
sheets of Drawings attached hereto, in all of which the same letters
refer to similar parts):-
Figure 1, represents a side elevation of my self-acting lithographic
press. Figure 2, the same in section, in order to exhibit more clearly
the wheels, 3, 4, and 6, and the levers by which the stone and inking
apparatus is put in and out of action, also the segment cylinder e, f, by
which the pressure is obtained under the scraper d. Figure 3, is a
plan or bird's-eye view of the frame and wheel work, the upper parts of
the press being removed, and is supposed to be taken at the line =,,
Figure 1. Figure 4, is a separate view of the damping apparatus.
Figure 5, is a left-hand detached view of the propeller M, and lifter L;

page_text: and Figure 6, is a side view of the damping apparatus, Figure 4. On
the several drawings are given the names of the parts to which the
letters refer; these will afford sufficient explanation to any workman or
other person conversant with lithographic printing. The action is com-
menced by causing the wheel and shaft to revolve, which communicates
motion to the wheels 3, 5, and 6. The proportions or number of teeth
in these wheels are so arranged that six revolutions of wheel 1, (by
which an impression is printed) the wheels 4, 5, and 6, make two revo-
lutions, and the wheel 3, makes one revolution. The wheel 1, may be
put in motion by steam, hand, or other motive power; that wheel com-
municates and puts in action the several parts, as seen by the Drawings,
and which any competent lithographic printer will clearly understand.
The whole operation-of damping, inking, and printing being done by
my machine, the paper alone requiring to be put down and removed by
a boy, as in letter-press printing machines.. I do not mean or intend to
claim any of the several parts shewn in the three sheets of Drawings
annexed, which are old and in use, (as the .inking rollers; &c.,) but
which it was necessary for the clear understanding of my Invention to
exhibit; but I do claim the various combinations of those parts as
shewn in the Drawings, whereby effects may be produced as therein
shewn, and especially the method of damping or wetting the stone,
the arrangement of the cylinder for giving the pressure, and the
arrangement or disposition of the excentrics and levers for producing
the various actions.
And whereas the several Drawings annexed are taken from a work-
ing model made by me, from which a full sized machine will now. be
constructed, and which may require some alterations to procure the
requisite strength of the several parts; I do not intend to confine my-
self to the exact forms or thicknesses of the several parts, should any of
them requiré modification.
