IMPROVEMENTS IN APPARATUS FOR FORMING AND SHAPING METALLIC ENDS AND COVERS FOR BOXES AND CASES
Year: 1873

page_text: LETTERS PATENT to Charles Frederick Parsons, of 24, Bermondsey
Wall, and 30 and 31, East Lane, Bermondsey, in the County of
Surrey, Paper and Wood Box Manufacturer, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR FORMING AND SHAPING METALLIC ENDS
AND COVERS FOR BOXES AND CASES."
Sealed the 15th May 1874, and dated the 18th November 1873.
PROVISIONAL SPECIFICATION left by the said Charles Frederick
Parsons at the Office of the Commissioners of Patents, with his
Petition, on the 18th November 1873.
I, CHARLES FREDERICK PARSONS, of 24, Bermondsey Wall, and 30
and 31, East Lane, Bermondsey, in the County of Surrey, Paper and
Wood Box Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR FORMING AND SHAPING
METALLIC ENDS AND COVERS FOR BOXES AND CASES," to be as follows:-
This Invention relates to improvements in apparatus for forming and
shaping metallic ends and lids or covers for boxes and cases.
The apparatus is composed of, say, two plungers, which are caused to:
rise and fall by cranks or eccentrics upon an overhead shaft, the plunger
rods working in guides fitted to or forming part of standards or uprights,

page_text: which are firmly bolted to a bed or foundation plate. The bed plate
carries matrices (adjustable), in which dies are free to rise under the
action of springs encircling their stems, and to be depressed by the
plungers or by dies fitted in them, as the case may be. The lower dies
are arranged in boxes, which are fitted into apertures under the bed
plate to facilitate their removal when desired.
In forming or shaping, say, the circular lid or cover of a box, a blank
disc is placed upon the matrix, and the plunger is brought down, which
forces it into the aperture, the pressure also forcing down the lower die
to the required depth to form a rim or raised edge all round the cover;
the plunger then lifts and the spring of the lower die pushes that die up,
and with it the shaped cover, about level with the top surface of the
matrix, from which it can be removed by hand.
The advantages derived by this Invention are, a greater number of
ends and covers can be made in a given time than is now accomplished,
less manual labour is required, and the ends and covers are not put out
of shape while being released from the matrices.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Frederick Parsons in the Great Seal Patent
Office on the 16th May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
FREDERICK PARSONS, of 24, Bermondsey Wall, and 30 and 31, East
Lane, Bermondsey, in the County of Surrey, Paper and Wood Box
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of November, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Frederick Parsons, Her special
licence that I, the said Charles Frederick Parsons, my executors, admi-
nistrators, and assigns, or such others as I, the said Charles Frederick
Parsons, 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

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN APPARATUS FOR FORMING AND SHAPING METALLIC ENDS AND
COVERS FOR BOXES AND CASES," upon the condition (amongst others) that I,
the said Charles Frederick Parsons, 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 Charles Frederick Parsons, 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
hereunto annexed, that is to say :-
This Invention relates to improvements in apparatus for forming and
shaping metallic ends and lids or covers for boxes and cases.
The apparatus is composed of two plungers A, B, Figures 1 and 2,
which are caused to rise and fall by excentrics O, D, upon an overhead.
shaft E, the plunger rods F, G, working in guides H, I, fitted to or
forming part of standards or uprights J, K, which are firmly bolted to a
bed or foundation plate L. The bed plate L carries matrices M, N,
(adjustable by screw pins R and removable); in which dies P are free to
rise under the action of springs S, as in the detached view, Figure 3,
which springs encircle their stems for the lower dies to be depressed by
the plungers A, B, or by dies fitted in them, as the case may be. The
lower dies P are arranged in boxes T, which are fitted into apertures in
or under the bed plate to facilitate their removal when desired. The
upper or lower die or both may be engraved or otherwise ornamented or
impressed for imparting the necessary device or inscriptions on or in the
lid or end being produced.
The operation is as follows for each side or end of the apparatus:-In
forming or shaping, say, a circular lid or cover of a box, a blank disc is
placed upon the matrix, and the plunger is brought down, which forces
it into the aperture, the pressure also forcing down the lower die to the
required depth to form a rim or raised edge all round the cover; the
plunger then lifts and the spring of the lower die pushes that die up,
and with it the shaped cover about lovel with the top surface of the

page_text: matrix, from which it can be removed by hand, generally by sliding it
off sideways into a receptacle by a fresh disc blank, while the attendant
is in the act of placing the new disc in position upon the matrix, and
while the upper die or plunger is lifting and descending again under the
action of its excentric, the movement being effected from a band upon
the fast pulley W, the other pulley V being loose for the strap X to be
shifted on to by the lever and fork Y when it is necessary to stop the
working of the apparatus. Z is a fly wheel for steadying and regulating
the motion.
The advantages derived by this Invention are, a greater number of 1
ends and covers can be made in a given time than is now accomplished.
Less manual labour is required, and the ends and covers are not put out
of shape while being released from the matrices.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,-
Firstly. The improvements in apparatus for forming and shaping
metallic ends and covers for boxes and cases, such apparatus being
arranged in the manner described and shown and acting in the manner
and for the purposes set forth.
Secondly. I claim the combination of a lower matrix, die, return 2
spring, and box when arranged in or to apparatus for forming and
shaping metallic ends and covers for boxes and cases, as set forth and
shown.
In witness whereof, I, the said Charles Frederick Parsons, have
hereunto set my hand and seal, this Fifteenth day of May, One 2
thousand eight hundred and seventy-four.
