CERTAIN IMPROVEMENTS IN MACHINERY FOR PRINTING
Year: 1855

page_text: LETTERS PATENT to William Brown, of No. 113, Albany Road, Old
Kent Road, in the Parish of Saint George, Camberwell, in the County
of Surrey, Engineer, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY FOR PRINTING."
Sealed the 17th August 1855, and dated the 26th February 1855.
PROVISIONAL SPECIFICATION left by the said William Brown at the
Office of the Commissioners of Patents, with his Petition, on the 26th
February 1855.
I, WILLIAM BROWN, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN MACHINERY FOR PRINTING" to be as follows; and
consists of improvements in the kind known as platten or surface machines.
The framing carries the platten, and the table, which rises and falls in order to
give the impression, carries the form of type, and is guided by a combination
of levers, known as a parallel motion, in order to retain the faces of the table
and platten always parallel to each other, and another combination of levers,
one point or centre of which is fixed to the framing, the said levers receiving
their motion from the table, the use of which is to traverse the inking rollers
which are in suitable bearings over the form, and give motion to the ink
doctor, vibrating rollers, &c. The platten and table may be reversed, and the
machine may be erected horizontally, vertically, or angular.

by the said William Brown in the Great Seal Patent Office on the
25th August 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BROWN, of Number 113, Albany Road, in the Parish of Saint George, Camber-
well, in the County of Surrey, Engineer, send grecting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of February, in the year of our
Lord One thousand eight hundred and fifty-five, in the eighteenth year of
Her reign, did, for Herself, Her, heirs and successors, give and grant unto
me, the said William Brown, Her special license that I, the said William
Brown, ny executors, administrators, and-assigns, or such others as I, the
said William Brown, my executors, 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
"CERTAIN IMPROVEMENTS IN MACHINERY FOR PRINTING," upon the condition,
amongst others, that I, the said William Brown, by an instrument in
writing under my hand and seal, 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 I, the said William Brown, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Drawing hereto annexed, and the
letters and figures marked thereon, that is to say :-
A is the driving shaft of the machine, connected by teeth wheels to B, the
crank; C is the table for carrying type, guided by the carriage D and parallel
motion rods E; F is the platten; G and G 1 are rollers for endless bands N
and return tapes N1; H is a pinion carrying a pall into the tooth of the
rotchet I; J is a spur wheel, connected by rod O to the crank shaft B, for
working what is called or known as feed motion; K is the inking apparatus;
L, L, are the inking rollers; M. are the arms or levers on carriage D, which are
connected by rods to the framing and to the carriages of the inking rollers L, L,
so as to give motion to the inking rollers.

page_text: Having thus described the several parts of the said machine, I now proceed
to shew how the same is to be used. Motion being given by steam or other
power to the driving shaft A, is thereby communicated to the crank B,
which causes the table C, carrying the type, to rise and fall, the face of
the table being always kept parallel with the face of the platten F by
means of the carriage D, and the parallel motion rods E; the carriage D
carries the arms M, and gives motion to the inking rollers L, L, for inking
the type, which is effected whilst the table is up or rising. On the descent or
fall of the table the rollers run back or recede to receive or renew their
supply of ink from the inking apparatus K. The paper, card, or other
material to be printed is placed or laid by hand or otherwise upon the endless
band N. Motion is communicated by rod O from the crank B by the spur
wheel J to the pinion H, which carries the pall into the tooth of the rotchet I,
and so gives notion to the roller G 1, which carries forward the endless band
with the paper, card, or other material, which paper, card, or other material
remains stationary upon it at the point required for receiving the impres-
sion, the tapes and return tapes at the same time pressing upon the sheet.
The pinion H has then a backward motion communicated to it until the pall
has passed the tooth in the rotchet, when the forward communication again
moves the rotchet, and so passes the paper, card, or other material continuously
on to receive the impression, which paper, card, or other material is then
delivered or discharged by the return of the tapes at N 1.
Having thus described the nature of the Invention, I wish it to be understood
that I confine my claim,-
First, to the use or application of a parallel motion for the purpose of
causing the surfaces of the table or platten to move parallel with each other.
Second, I claim the carriage D and combination of levers M for giving
motion to or traversing the inking rollers.
Third, I claim the general arrangement of the machine with the pinion,
rotchet, and spur wheel, as above described, for feeding the machine with
paper, card, or other material.
In witness whereof, I, the said William Brown, have hereunto set my
hand and seal, this Twenty-fifth day of August, One thousand eight
hundred and fifty-five.
