page_text: LETTERS PATENT to William Simmons and George Walter Simmons,
both of Penge, in the County of Surrey, and George Smith, of
the Strand, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN THE MEANS, METHOD, AND APPARATUS FOR .PRINTING
TANYAWA "
PROVISIONAL SPECIFICATION left by the said William Simmons,
George Walter Simmons, and George Smith at the Office of the
Commissioners of Patents, with their Petition, on the 10th October
1871.
We, WILLIAM SIMMONS and GEORGE WALTER SIMMONS, both of
Penge, in the County of Surrey, and GEORGE SMITH, of the Strand, in
the County of Middlesex, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN THE MEANS, METHOD, AND APPARATUS FOR
PRINTING ZINCOGRAPHIC AND OTHER IMPRESSIONS," to be as follows:-
This Invention relates to improvements in the means, method, and
apparatus for printing zincographic impressions by which the paper

page_text: or other material to be printed is conducted between two cylinders
or rollers having printing surfaces bent around them so as to print one
or more impressions at the same time, the zinc plates or other printing
surfaces being readily applied to or removed from the cylinders.
For this purpose in carrying out our improvements the designs or subject
matter to be printed is first drawn upon or transferred to the surface
of a plate of zinc or other metal or material, as is well understood and in
common practice. The zinc or other plates thus prepared ready for
printing are then bent into a curved or semicircular form, and secured
in any convenient manner upon part of the circumference of the rollers
or cylinders mounted upon axes so as to revolve in suitable bearings
carried by the framing of the printing machine.
Each roller is formed with a recess for the insertion of the hand or
of an instrument to take hold of the impression as it comes out from
between the rollers in the process of printing; part of the surface or cir-
cumference of the cylinders is lower than the printing surface, and upon
this surface the ink is distributed, the inking rollers arranged around
the circumference of the cylinders being caused to descend on to this
lower inking surface after the printing surface has rotated beyond them.
Suitable damping rollers are arranged in front of the inking rollers to
damp or moisten the printing surface before it is presented to the inking
rollers. Felt or other suitable elastic or yielding material is placed upon
the surface of the cylinder underneath the zinc plate or other printing
surface to impart a slight degree of elasticity thereto.
The cylinders, damping and inking rollers are actuated by suitable
mechanism as is well understood.
By this means printed impressions can be obtained from zinc or
other plates mounted upon cylinders as previously described as fast as
the paper can be fed and passed through between them.

"
filed by the said William Simmons, George Walter Simmons, and
George Smith in the Great Seal Patent Office on the 10th April
1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
SIMMONS and GEORGE WALTER SIMMONS, both of Penge, in the County
of Surrey, and GEORGE SMITH, of the Strand, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of October, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said William Simmons, George Walter Simmons,
and George Smith, Her special licence that we, the said William
Simmons, George Walter Simmons, and George Smith, our executors,
administrators, and assigns, or such others as we, the said William
Simmons, George Walter Simmons, and George Smith, our exécutors,
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 THE MEANS,
METHOD, AND APPARATUS FOR PRINTING ZINCOGRAPHIC AND OTHER IMPRESSIONS,'
upon the condition (amongst others) that we, the said William Simmons,
George Walter Simmons, and George Smith, our executors or adminis-
trators, by an instrument in writing under our, or their, or one of their
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 we, the said William Simmons, George Walter
Simmons, on behalf of ourselves and the said George Smith, do hereby
declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement tliercof, that is to say :—

page_text: This Invention relates to improvements in the means, method, and
apparatus for printing zincographic impressions by which the paper or
other material to be printed, is conducted between two cylinders or
rollers having printing surfaces bent around them so as to print one or
more impressions at the same time, the zinc plates or other similar 5
printing surfaces being readily applied to or removed from the cylinders.
For this purpose in carrying out our improvements the designs or
subject-matter to be printed is first drawn upon or transferred to the
surface of a plate of zinc or other metal or material, as is well under-
stood and in common practice. The zinc or other plates thus prepared 1
ready for printing are then bent into a curved or semicircular form, and
secured in any convenient manner upon part of the circumference of
the rollers or cylinders mounted upon axes so as to revolve in suitable
bearings carried by the framing of the printing machine.
Each roller is formed with a recess for the insertion of the hand or 1
of an instrument to take hold of the impression as it comes out from
between the rollers in the process of printing; part of the surface or
circumference of the cylinders is lower than the printing surface, and
upon this surface the ink is distributed, the inking rollers arranged
around the circumference of the cylinders being caused do descend on
to this lower inking surface after the printing surface has rotated beyond
them. Suitable damping rollers are arranged in front of the inking
rollers to damp or moisten the printing surface before it is presented
to the inking rollers. Felt or other suitable elastic or yielding material
is placed upon the surfaces of the cylinders underneath the zinc plates
or other printing surfaces to impart a slight degree of elasticity thereto.
The cylinders, damping and inking rollers are actuated by suitable
mechanism as is well understood.
By this means printed impressions can be obtained from zino or other
plates mounted upon cylinders as previously described, as fast as the s
paper can be fed and passed through between them.
And in order that our Invention may be more clearly understood and
readily carried into practice, we will proceed to describe the Drawing
hercunto annexed, which shews a side view and an end view of a
zincographic printing machine arranged in accordance with our im-
provements.

page_text: A and B are the cylinders or rollers upon part of the circumference
of which the zinc plates or other similar printing surfaces are mounted
and secured in any convenient manner, being bent so as to fit accurately
on to the circumference of the cylinders A and B. Blanketing or other
suitable elastic material is placed underneath the zinc plates or other
similar printing surfaces in order to impart a slight degree of elasticity
thereto. a, b, are the rollers which supply the printing ink to the
vibrating rollers a', b', which transmit the ink to the distributing
surface of each of the cylinders A, B. The surface of each cylinder
upon which the ink is distributed is rather below the printing surfaces
in order to prevent the damping rollers from acting thereon, the inking
rollers being drawn or forced by springs or otherwise on to the dis-
tributing surfaces during their revolution. a³, 63, are the damping
rollers, and a, b, the inking and distributing rollers, which are supported
and revolve in bearings formed in brackets bolted to standards at each
side of the machine, the rollers being drawn towards the surface of the
cylinders by springs, as shown in the Drawing. c is the driving axis
which may be actuated by the crank handle c¹ or by pulleys c+ actuated
by a steam engine or other motive power. The toothed pinion c³ fixed
on the axis c takes into and drives a toothed wheel fixed on the axis
of the lower cylinder or roller B, which transmits motion to the
cylinder A by means of a corresponding toothed wheel a* fixed upon
its axis. The vibrating inking rollers a', 6', carried by the levers a*, b*,
are actuated by means of eccentrics upon the axes of the cylinders A, B,
as will be readily understood on examining the Drawings. The bearings
of the upper roller A are capable of adjustment by set screws, as shown.
D is the table upon which the paper or other material to be printed
is laid, the table having a to-and-fro movement imparted thereto so as to
present the edge of the paper to be gripped and carried through between
the printing surfaces mounted upon the cylinders as they revolve. A
small amount of horizontal motion is communicated to the table D
through the lever ďand rod ď³ by means of an eccentric upon the axis
of the cylinder B. F is the taking-off table, and any one acquainted
with the operations of cylinder printing from the foregoing description
will readily understand the working of machinery arranged in accordance
with our improvements as previously described.
.
'
Our improvements may be readily applied to ordinary cylindrical
letter-press printing machines by applying the bent zinc plates or other
similar printing surfaces thereto as previously described.

page_text: Having thus described the nature of our Invention and the manner
of carrying the same into practice, we would have it understood that
we do not confine ourselves to the exact details herein described, as the
means, method, and apparatus employed for carrying our Invention into
practice may be considerably varied without departing from the main à
features thereof; but what we claim is, the printing of zincographic
and other similar impressions from printing surfaces consisting of plates
of zinc or other suitable metal or material bent and applied to the
surfaces of the cylinders A and B, substantially as herein-before described
and shewn in the accompanying Drawing.
In witness whereof, we, the said William Simmons and Georgo
Walter Simmons, have hereunto set our hand and seal, this Tenth
day of April, in the year of our Lord One thousand eight hundred
and seventy-two.
