IMPROVED CONSTRUCTION OF MACHINES, AND THE FITTING OF APPLIANCES THEREIN, POR STAMPING, PUNCHING, AND EMBOSSING
Year: 1872

page_text: LETTERS PATENT to Alfred Smith, of Ilford, in the County of Essex,
Engineer, for the Invention of "IMPROVED CONSTRUCTION OF MACHINES,
AND THE FITTING OF APPLIANCES THEREIN, POR STAMPING, PUNCHING, AND
EMBOSSING."
PROVISIONAL SPECIFICATION left by the said Alfred Smith at the
Office of the Commissioners of Patents, with his Petition, on the
6th September 1872.
I, ALFRED SMITH, of Ilford, in the County of Essex, Engineer, do
hereby declare the nature of the said Invention for "IMPROVED CON-
STRUCTION OF MACHINES, AND THE FITTING OF APPLIANCES THEREIN, FOR STAMPING,
PUNCHING, AND EMBOSSING," to be as follows:-
This Invention relates to improved construction of machines, and
appliances, for stamping, punching, and embossing, and is intended.
chiefly to be used in the manufacture of paper collars.
This machine consists of a square casting with a bed plate in the
front, upon or towards which a press head is caused to descend inter-
mittently by the action of a beam or rock rever; moved by a cam or

eccentric from the back of the frame, the eccentric shaft being actuated
direct by band from the main shaft for maintaining the power and
motion. The press head extends to the sides, and has rods depending
and working through sockets to ensure the positive up-and-down motion
over the bed plate for the "register. The arms or trunnions of the
beam are carried by projections on or forming part of the side frames,
the arms being in such a position relatively to the centre as will
determine the proper length of the stroke, and to obtain the required
power for the stamping, punching, and embossing process.
.
For ensuring the fitting in or applying the proper plates or dies in
the patterns for stamping, punching, and embossing, pins, studs, and
grooves are arranged in opposite faces of the opposite pieces, these being
so arranged as to prevent the liability of either of them being fitted in
in wrong positions or places. The pins, studs, and grooves are employed
in connection with angle faces of the dies and patterns into which they
slide.
I sometimes make the faces of each die bolder in the pattern of a
different angle to ensure their dies fitting in their proper places; by
either of the above means the non-interchangability of the dies are
secured.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Smith in the Great Seal Patent Office on
the 6th March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
SMITH, of Ilford, in the County of Essex, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of September, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Alfred Smith, Her special licence that I, the
said Alfred Smith, my executors, administrators, and assigns, or such
others as I, the said Alfred Smith, 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

page_text: 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 "IMPROVED CONSTRUCTION OF MACHINES, AND
THE FITTING OF APPLIANCES THEREIN, FOR STAMPING, PUNCHING, AND EMBOSSING,"
upon the condition (amongst others) that I, the said Alfred Smith,
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 Alfred Smith, 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 thereof, reference being had to the Drawings here-
unto annexed, that is to say:-
This Invention relates to improved construction of machines and
appliances for stamping, punching, and embossing, and is intended
chiefly to be used in the manufacture of paper collars.
This machine consists, as shown at Figures 1 and 2 in the accompany-
ing Drawings, of a square casting A with a bed plate B in the front,
upon, or towards which a press head C is caused to descend inter-
mittently by the action of a beam or rock lever D moved by a cam or
eccentric E from the back of the frame, the eccentric shaft F being
actuated direct by band from the main shaft over the rigger G for
maintaining the power and motion. The press head C extends to the
sides, and has rods H, H, depending and working through sockets I, I, to
ensure the positive up-and-down motion over the bed plate for the
"register. The arms or trunnions J, J, of the beam are carried by one
or more projections K on or forming part of the side frames, the arms
being in such a position relatively to the centre as will determine the
proper length of the stroke and to obtain the required power for the
stamping, punching, and embossing process.
"
For insuring the fitting in or applying the proper plates or dies in the
patterns for stamping, punching, and embossing, pins, studs, and grooves
are arranged in opposite faces of the opposite pieces, as shown in
Figures 3, 4, 5, and 6, these being so' arranged as to prevent the
liability of either of them being fitted in wrong positions or places.

page_text: The pins or studs P, P, and grooves L, L, are employed in connection
with angle faces of the dies M, M, and patterns, into which they slide.
I sometimes make the faces of each die holder in the pattern of a
different angle, to ensure their dies fitting in their proper places, and
the non-interchangability of the dies is secured thereby. The angles at
the sides of the grooves correspond with the angles of the dies, each pair
of them being different to prevent the possibility of one being placed in
the wrong holder. By this means a perfect system of working can be
maintained even in the hands of non-experienced operatives. The same
is also the case if the pin system first explained is employed. Here each 1
pin is arranged at a different portion of the plate to that of any other
pin of the other plates, and the holders are grooved correspondingly to
prevent mistakes happening, and the goods being spoiled or wrongly
marked or embossed.
And having now described the nature of my said Invention, and in 1
what manner the same is to be performed, I declare that I claim,--
Firstly. The improved construction of machine for the purposes set
forth with the side guides in combination for establishing a positive up-
and-down register of the die, as described and shown.
Secondly. The improved arrangements of the rock lever or beam a
worked by an eccentric cam at the back, as shown.
Thirdly. The method of operating the dies and press head from a back
shaft, as shown, for the purposes set forth.
And Fourthly. The improved method of ensuring the non-inter-
changability of the dies and die holders of machines employed, for the
purposes set forth as described.
In witness whereof, I, the said Alfred Smith, have hereunto set my
hand and seal, this Fourth day of March, One thousand eight
hundred and seventy-three..
