IMPROVEMENTS IN APPARATUS FOR PRINTING OR ENDORSING
Year: 1868

page_text: LETTERS PATENT to Giovanni Battista Puricelli, of Alfred Street,
Bedford Square, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR PRINTING OR ENDORSING."
Sealed the 12th January 1869, and dated the 13th July 1868.
PROVISIONAL SPECIFICATION left by the said Giovanni Battista
Puricelli at the Office of the Commissioners of Patents, with his
Petition, on the 13th July 1868.
I, GIOVANNI BATTISTA PURICELLI, of Alfred Street, Bedford Square,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR PRINTING OR ENDORSING,"
to be as follows:-
My Invention relates to apparatus to be used for printing or endorsing
purposes, such as for printing names and addresses or otherwise marking
wrappers and bags of all kinds, packing cases, and otherwise applicable
for marking purposes generally.

page_text: The apparatus consists of a spring cylinder fitted to rotate on a fixed
axis carried on a suitable frame provided with a handle. Around the
circumference of this spring cylinder is placed a strip of india-rubber or
other suitable material, on which are formed the letters or design to be
marked or printed. An adjustable inking roller is mounted in bearings
on the frame above mentioned in front of the printing cylinder, against
which it is caused to bear by the aid of spiral or other springs attached
to the movable axis of the inking roller. On either end of the printing
cylinder is a raised india-rubber band or rim against which the inking
roller bears in rotating, as well as against the type or design on the
cylinder before mentioned, so as to ensure a uniform pressure. When
using the printing cylinder it is passed once over the surface to be marked
by hand so as to coil its spring, one revolution producing the desired
impression, during which time the inking roller maintains a constant
supply to said type cylinder. The cylinder is then removed and returns
to its normal position by the uncoiling of the spring attached to its axis.
A stop is provided on the cylinder, which comes in contact with the frame
and limits the motion to one revolution in either direction. The inking
roller consists of a hollow perforated cylinder covered with flannel, felt,
or other suitable substance, which cylinder I fill with ink through an
opening at one end. The ink passing through the perforations permeates
the flannel, and as the roller is rotated by the motion of the printing
cylinder against which it bears the type on the latter is kept continually
supplied with ink. The india-rubber type strip may be readily detached
from the printing cylinder and another substituted when required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Giovanni Battista Puricelli in the Great Seal Patent.
Office on the 12th January 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GIOVANNI
BATTISTA PURICELLI, of Alfred Street, Bedford Square, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of July, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,

page_text: give and grant unto me, the said Giovanni Battista Puricelli, Her special
licence that I, the said Giovanni Battista Puricelli, my executors, adminis-
trators, and assigns, or such others as I, the said Giovanni Battista
Puricelli, 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
"IMPROVEMENTS IN APPARATUS FOR PRINTING OR ENDORSING," upon the con-
dition (amongst others) that I, the said Giovanni Battista Puricolli, my
executors or administrators, by an instrument in writing under my, 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 I, the said Giovanni Battista Puricelli, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Sheet of Drawings (that is to say) :-
:-
My Invention relates to apparatus to be used for printing or endorsing
purposes, such as for printing names and addresses, or otherwise marking
wrappers and bags of all kinds, packing cases, &c., and is otherwise
applicable for marking purposes generally.
The apparatus consists of a spring cylinder fitted to rotate on a fixed
axis carried on a suitable frame provided with a handle. Around the
circumference of this spring cylinder is placed a strip of india-rubber or
other suitable material, on which are formed the letters or design to be
inarked or printed. An adjustable inking roller is mounted in bearings
on the frame above mentioned in front of the printing cylinder, against
which it is caused to bear by the aid of spiral or other springs attached
to the moveable axis of the printing roller. On either end of the printing
cylinder is raised an india-rubber band or rim against which the inking
roller bears in rotating, as well as against the type or design on the
cylinder before mentioned, so as to ensure an uniform pressure. When
in use the printing cylinder is passed once over the surface to be marked
so as to coil its spring, one revolution producing the desired impression,

page_text: during which time the inking roller maintains a constant supply of ink
to the said type cylinder. The apparatus is then removed from the
material, and the cylinder returns to its normal position by the uncoiling
of the spring attached to its axis. A stop is provided on the cylinder,
which comes in contact with the frame and limits the motion to one
revolution in either direction. The inking roller consists of a hollow
perforated cylinder covered with flannel, felt, or other suitable substance,
which cylinder I fill with ink through an opening at one end. The ink
passing through the perforations permeates the flannel, and as the roller
is rotated by the motion of the printing cylinder against which it bears
the type on the latter are kept continually supplied with ink. The
india-rubber type may be readily detached from the printing cylinder
and another substituted when required.
In order that my Invention may be clearly understood, I will explain
the same with reference to the accompanying Sheet of Drawings, in which
Figure 1 is a section through the centre of the marking cylinder, and
Figure 2 a side view of the apparatus.
a is the marking cylinder revolving in bearings 6 on the shaft c. At
the right-hand side of the cylinder the ribs d are thicker than at the left-
hand side, so that a recess e may be formed in the centre thereof, in
which recess is coiled around the shaft c the spring f, fastened at its inner
end to the said shaft and at its outer end to one of the ribs, as shewn
at g, Figure 2. The india-rubber rings h are sprung around the cylinder a,
and rest in the grooves i, and the strip of india-rubber or other material K,
on which the letters or device is formed (parts of the said letters being
shewn in section), is fastened around the cylinder a by screws 1, or by
any other suitable means, so that it can be easily removed and exchanged.
The perforated zinc or other cylinder m is filled with ink or other dye
through the opening n, closed by a cork n' or otherwise, the ink per-
meating the layers of flannel o, which are brought into constant contact
with the letters by the springs p acting on washers 9 on the spindles r,
the said spindles being screwed or otherwise fastened into the cylinder
ends 8, and being free to move in their bearings in the direction of the
pull of the springs p. Recesses t are formed in the outer ends of the
ribs, in one of which is the pin u, which after each revolution of the
cylinder a in either direction strikes against the screw v, so that the said
cylinder cannot make more than one revolution without being brought
back to its first position by the spring f.

page_text: Having now described the nature and particulars of my said Invention,
I claim, the improvements in apparatus for printing or endorsing, as
herein described and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Giovanni Battista Puricelli, have
hereunto set my hand and seal, this Ninth day of January
in the year of our Lord One thousand eight hundred and sixty-
nine.
