IMPROVEMENTS IN A "LINK PRESS" FOR MAKING EARTHENWARE AND OTHER PURPOSES to be as follows:
Year: 1885

page_text: We FREDERIC GEORGE JOHNSON and ALFRED JOHNSON both of Charles Street
Works, Hanley, in the County of Stafford Earthenware Manufacturers do hereby
declare the nature of our invention for "IMPROVEMENTS IN A "LINK PRESS"
FOR MAKING EARTHENWARE AND OTHER PURPOSES to be as follows:-
"
"
This invention of ours relates to improvements in the making of "Link presses'
in a simple and direct manner and the advantages of the same over and above
those now in use is that only a certain power can be brought down to bear on the
mould or die by being made with links so that at a certain point they reverse
causing the pressure to be taken off again, this is fully shown in the accompanying
drawing F. F and which will be found to be a great improvement on those now in
use. The following is a full description of said drawing.
Letter A represents the lever made of wrought iron which when pulled down
gives motion to the links F. making them perpendicular and pressing the ram C.
down, to which a mould or die is fixed which makes the desired article.
B. Is the cast iron frame work of the machine.
C. Is a spindle or ram and is made of wrought iron planed up to slide in
bracket H.
D. Is a weight attached to lever A with a set pin to same and balances machine
and when lever is loosed pulls ram C. into its proper place again as shown in
Drawing.
E. Is a screw for adjusting ram C. with lock nuts K to make different thicknesses
of ware as desired.
F. Links by which a certain power can be brought into action on the article to
be produced and no more than is necessary. The power is brought to bear.on
same when the links F. are perpendicular, they then reverse if the lever is still
pulled down and heaves the ram off the work again.
G. Is 2 set pins to screw cap on bracket H for ram to slide in."
H. Cast iron bracket, screwed to frame B.
I. Is the jaw on end of adjusting screw E. to which end of links F. is coupled.
J. Is a set pin to screw cast iron bracket to frame, which carries a small shaft to
which the lever A and the crank F. is keyed on.
This we think is a great improvement on the present make of presses.

statement:
This invention of ours relates to improvements in the making of Link Presses

with our Provisional Specification F. F. and which will be found to be a great
improvement on those now in use. The following is a full description of said
drawing.
Letter A represents the lever made of wrought iron which when pulled down
gives motion to the links "F" making them perpendicular and pressing the
ram C" down, to which a mould or die is fixed which makes the desired article.
"B" is the cast iron frame work of the machine.
"I
C" is a spindle or ram and is made of wrought iron planed up to slide in
bracket "H"

"D" is a weight attached to lever" A" with a set pin to same which balances
machine and when the lever is loosed pulls ram C" into its proper place again as
shown in drawing,
"E" is a screw for adjusting ram "C" with
thicknesses of ware as desired.
lock-nuts "K" to make different
"F" links by which a certain power can be brought into action on the article
to be produced and no more than is necessary. The power is brought to bear on
same, when, the links F" are perpendicular, they then reverse if the lever is
still pulled down and heaves the ram off the work again,

"
Ġ" are 2 set pins to screw cap on bracket "H" for ram to slide in.
H" cast iron bracket screwed to frame "B."
'I" is the jaw on end of adjusting screw "E" to which end of links "F" are
coupled.
.
"J" is a set pin to screw cast iron bracket to frame which carries a small shaft
to which the lever "A" and the crank "F" is keyed on.

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is:-
Firstly. The use of the "Link Press" for pressing Earthenware, metals and
other substances.
