Year: 1860

page_text: LETTERS PATENT to Charles John Hill, of Froliche Cottage, Turnham
Green, in the County of Middlesex, for the Invention of "IMPROVEMENTS
IN PRESSES FOR STAMPING MEDALS, EMBOSSING AND CUTTING OR PUNCHING
OUT METAL OR PAPER, AND PRINTING ON PAPER, LINEN, OR ANY OTHER
MATERIAL."
Sealed the 4th June 1861, and dated the 7th December 1860.
PROVISIONAL SPECIFICATION left by the said Charles John Hill at
the Office of the Commissioners of Patents, with his Petition, on the
7th December 1860.
I, CHARLES JOHN HILL, of Froliche Cottage, Turnham Green, in the County
of Middlesex, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN PRESSES FOR STAMPING MEDALS, EMBOSSING AND CUTTING OR
PUNCHING OUT METAL OR PAPER, AND PRINTING ON PAPER, LINEN, OR ANY OTHER
MATERIAL," to be as follows:-
My Invention consists of a direct acting press so constructed that it may
be worked either with one or more levers, or the blow struck by weight or by
hand, and is formed, when employed for coining or stamping metal, or when
rapid action is required, of a strong metal frame, to which the following parts
are attached, viz. :-A hollow vertical plunger, to contain or be connected with
another plunger, which I prefer acting inside the former, so as to counteract
the rotary influence of the action of the lever or levers herein-after described, the
top part of which inner plunger extends above the outer plunger to the extent

page_text: required to reach the said lever or levers. The said outer plunger to be
attached to and suspended by one or more springs when more than one spring
are used; they should be placed one at the top and one at the bottom of outer
plunger parallel to each other, that portion of the said springs where the outer
plunger is attached to be raised higher than the parts attached to the frame-
work. Above the said inner plunger are two levers working on fulcrums, so
arranged that by the alternate action of the levers double the number of blows
or depressions are given to the plungers than by the ordinary lever press; this
is effected by the fulcrums being placed in a horizontal plane equidistant to
centre of top of inner plunger; that part of each of the levers which acts on
the plunger is of circular form corresponding to the top of plunger, the blow
being given at that time when the lever is at right angles with the plunger,
whereby a direct blow is produced, so that on depressing either lever the blow
is given, the other is raised, and so on alternately; these levers are connected
together by a double tee-bolt working in bearings, and are weighted at their
extremities or power ends. This form of lever I term a compound loaded
lever. When rapidity of action is not required I dispense with one of the
levers and the couplings; it may then be termed a single direct-acting loaded
lever press, or the levers may both be dispensed with, and the blow struck on
the top of a then single and solid plunger, either by weight or by hand,
according to the force required, the spring or springs remaining as before
described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles John Hill in the Great Seal Patent Office on the
7th June 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
JOHN HILL, of Froliche Cottage, Turnham Green, in the Parish of Chiswick,
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of December, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles John Hill, Her special licence that I, the said Charles John Hill,
my executors, administrators, and assigns, or such others as I, the said
Charles John Hill, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-

page_text: after 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 "IM-
PROVEMENTS IN PRESSES FOR STAMPING MEDALS, EMBOSSING AND CUTTING OR
PUNCHING OUT METAL OR PAPER, AND PRINTING ON PAPER, LINEN, OR ANY OTHER
MATERIAL," upon the condition (amongst others) that I, the said Charles
John Hill, 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 John Hill, 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, and the accompanying Drawings, that is to say:-
My Invention consists of a direct-acting press, so constructed that it may
be worked either with one or more levers, or the blow struck by weight, or by
hand, and is formed, when employed for coining or stamping metal, or when
rapid action is required, of a strong metal frame, to which the following parts
are attached, viz. :-A hollow verticle plunger, to contain or be connected.
with another plunger, which I prefer acting inside the former, so as to
counteract the rotary influence of the action of the lever or levers herein-after
described, the top part of which inner plunger extends above the outer plunger
to the extent required to reach the said lever or levers. The said outer
plunger to be attached to and suspended by one or more springs,, when more
than one spring are used they should be placed one at the top and one at the
bottom of outer plunger parallel to each other, that portion of the said springs.
where the outer plunger is attached to be raised higher than the parts
attached to framework. Above the said inner plunger are two levers working
on fulcrums, so arranged that by the alternate action of the levers double the
number of blows or depressions are given to the plungers than, by the ordinary
lever press; this is effected by the fulcrums being placed in a horizontal plane-
equidistant to centre of top of inner plunger; that part of each of the levers
which acts on the plunger is of circular form corresponding to the top of
plunger, the blow being given at that time when the lever is at right angles.
with the plunger, whereby a direct blow is produced, so that on depressing
either lever the blow is given the other is raised, and so on.alternately; these
levers are connected together by a double tee-bolt working in bearings, and

solid plunger C, C. The size of these presses must entirely depend on the
purposes for which they are required.

page_text: Having thus described the nature of my Invention, and the construction of
the same, I wish it to be understood I do not limit myself to the precise
details, nor do I claim the loading of a lever as new; but I claim the con-
struction of a press or presses, as herein shown, the application of the loaded
lever or levers for the purpose of collecting power during the passage through
the space allowed, and delivering the accumulated force at the instant either
of the levers and the plungers are at right angles, for all the uses and purposes
set forth in the title of this my Invention; the peculiar conformation and
combination of levers, as described and shown in the Drawings, and their mode
of action on the plungers, together with the arrangement of plungers and
springs, as herein-before set forth.
In witness whereof, I, the said Charles John Hill, have hereunto set my
hand and seal, this Seventh day of June, in the year of our Lord
One thousand eight hundred and sixty-one.
