Year: 1864

page_text: LETTERS PATENT to John Abraham, of Birmingham, in the County of
Warwick, Machinist, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR COINING."
Sealed the 7th October 1864, and dated the 21st April 1864.
PROVISIONAL SPECIFICATION left by the said John Abraham at the
Office of the Commissioners of Patents, with his Petition, on the 21st
April 1864.
I, JOHN ABRAHAM, of Birmingham, in the County of Warwick, Machinist,
"do hereby declare the nature of the said. Invention for "IMPROVEMENTS IN
MACHINERY FOR COINING," to be as follows:-
In machinery. for coining, as ordinarily constructed, the blanks to be made
into coins are cut out in one machine, and the blanks are next placed in
another and separate machine, where they are milled or marked on their
edges, and the milled or marked blanks are afterwards stamped or impressed
in a third machine or press.
My Invention consists in constructing or arranging machinery for coining
in the manner herein-after explained, whereby the blanks to be made into
coins are cut out, and the edges of the blanks milled or marked in the same
machine. I feed the metal from which the blanks are to be cut out by means
of feeding rolls to the dies and punches for cutting out the said blanks, the
said metal having an intermittent motion given to it by the rolls. The metal
fed by the rolls may either be situated vertically or horizontally. The blanks

page_text: cut out by the dies and punches fall through guides or are guided in their fall
in any convenient way to the grooves in the periphery of a revolving milling
disc or wheel, by which said dise or wheel the edges of the blanks are milled
or marked. The milled blanks afterwards fall from the milling dise or wheel
into a box or other receptacle. The feeding rolls are driven by a ratchet
wheel, the punches are worked by a crank or excentric, and the milling wheel
is fixed on and worked by the main shaft.
The essence of my Invention consists in arranging or combining the parts
of machinery for coining, so that the cutting out of the blanks and the milling
or marking of the edges of the said blanks are effected in the same machine,
or in so combining or arranging a cutting-out machine with a milling or
marking machine that the blanks cut out by the former are conveyed without
being touched by the hand to the latter, where they are milled or marked on
their edges.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Abraham in the Great Seal Patent Office on the
21st October 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ABRAHAM, of Birmingham, in the County of Warwick, Machinist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date. the Twenty-first day of April, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year.
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Abraham, Her special licence that I, the said John
Abraham, my executors, administrators, and assigns, or such others as I, the
said John Abraham, 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, usė, 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 MACHINERY FOR COINING," upon the condition (amongst others)
that I, the said John Abraham, my executors or administrators, by an instru-
ment 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
ayhat manner the same was to be performed, and cause the same to be filed

page_text: in the Great Seal Patent Office within six. calendar months next and imme
diately after the date of the said Letters Patent.
.
NOW KNOW YE, that I, the said John Abraham, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol
lowing statement thereof, that is to say :-
:
In machinery for coining, as ordinarily constructed, the blanks to be made
into coins are cut out in one machine, and the blanks are next placed in
another and separate machine where they are milled or marked on their edges;
and the milled or marked blanks are. afterwards stamped or impressed in a
third machine or press.
My Invention consists in constructing or arranging machinery for coining
in the manner herein-after explained, whereby the blanks to be made into
coins are cut out, and the edges of the blanks milled or marked in the same
machine. I feed the metal from which the blanks are to be cut out by means
of feeding rolls to the dies and punches for cutting out the said blanks; the
said metal having an intermittent motion given to it by the rolls. The metal
fed by the rolls may either be situated vertically or horizontally, and the parts of
the machine may either work vertically or horizontally, or in any intermediate
plane without departing from the nature of the Invention. The blanks cut
out by the dies and punches fall through guides, or are guided in their fall in
any convenient way to the grooves in the periphery of a revolving milling
disc or wheel, by which said disc or wheel the edges of the blanks are
milled or marked. The milled blanks afterwards fall from the milling disc or
wheel into a box or other receptacle. The feeding rolls are driven by a
ratchet wheel, the punches are worked by a crank or excentric, and the
milling wheel is fixed on and worked by the main shaft.
The essence of my Invention consists in arranging or combining the parts of
machinery for coining so that the cutting out of the blanks and the milling or
marking of the edges of the said blanks are effected in the same machine, or
in so combining or arranging a cutting out machine with a milling or marking
machine, that the blanks cut out by the former are conveyed without being.
touched by the land to the latter, where they are milled or marked on their.-
edges.
Having explained the nature of my Invention, I will proceed to describe,
with reference to the accompanying Drawings, the manner in which the same
is to be performed.
Figure 1 represents in side elevation a machine for cutting out blanks for.
coins and for milling the said blanks, constructed according to my Invention;

page_text: :
Figure 2 is an end elevation of the same; Figure 3 is a plan of the same;
Figure 4 is a longitudinal section of the same, taken through the line a; b, of
Figure 3; and Figure 5 is a transverse section of the same taken at the
line c, d, Figure 3; Figure 6 represents a portion of the machine as herein-
after explained. The same letters indicate the same parts in each Figure."
The metal from which the blanks are to be cut is fed into the machine by.
means of the pair of vertical rolls e, e, and the waste metal is removed from
the machine by means of the pair of vertical rolls f, f, at the opposite side of
the machine. The sheet metal being fed into the machine is marked g, and
the waste metal being removed from the machine is marked h in Figures 3.
and 5. The rolls e and f have an intermittent rotatory motion communicated.
to them in the manner herein-after explained. The metal g is fed by the rolls
ácross a series of three fixed hollow dies i situated in an oblique line one.
ábove the other in the bed k. Working in a line with each of the fixed:
liollow dies is a punch 1 fixed in the ram or plunger m. A greater or less
number of punches and fixed dies than three may be used. The required
reciprocating motion is given to the punches in the manner herein-after
explained. By the operation of the said punches blanks are cut out from the
sheet metal fed into the machine. Each of the hollow fixed dies i com-
municates at back with a spout or guide n, and the blanks cut out by the
operation of the punches pass down the said spouts or guides to the grooves p
(see Figure 4) in the periphery of a rotating milling disc or wheel 9, the
bottom end of each of the said spouts or guides n opening over a groove, in
the said milling disc or wheel, as will be understood by an examination of
Figure 4. By the rotation of the milling disc or wheel 9 the blanks are
carried against the fixed milling plate r, and thereby milled, and the milled
blanks then fall from the machine. The milling disc or wheel 7 and fixed.
plate r are of the ordinary construction, I therefore do not think a detailed
description of the said parts necessary. The motions of the several moving
parts are obtained in the following manner :-s is the driving shaft, provided.
with fast and loose pulleys t, t, and fly wheel u. The said shaft s works in
bearings at w, a, carried by the framing of the machine, and to the end of the
said shaft s the rotating milling disc or wheel q is connected in the manner
represented in Figure 4. On the driving shaft s is a bevil pinion, which,
gears with a bevil toothed wheel 2 on the vertical shaft 3. On the upper end
of the shaft 3 is a crank or excentric 4 (see Figure 4), working in and giving
motion to the slide 5 on the bed 6 of the machine. To this slide 5 the ram
or plunger m carrying the series of punches l'is fixed by means of the screws
7 and nuts 8. By the motion of the shaft 3 transmitted from the driving

page_text: shaft s.by. means of the bevil gearing 2, 2, the crank or excentric 4 on the end
of the shaft 3 gives a reciprocating sliding motion to the slide 5, and throughi
the said slide 5 to the ram or plunger-m and punches 1. The intermittent
rotatory motion of the two pairs of rolls e. and f is effected by means of the
Imechanism represented separately in Figure 6; part of which is also represented
in Figure 1. On the vertical shaft 3 is an excentric 10, the connecting rod 11
of which excentric has at its end'a bell-crank lever 12, turning, loosely on the
axis of one of the rolls f, f. On the axis of the roll upon which the
lever 12 turns a ratchet wheel 13 is fixed, and on the axis of one of the
rolls e a similar ratchet wheel 14 is fixed. An arm or lever 15 turning
loosely on the axis carrying the ratchet wheel 14 is connected by the con-
necting rod 16 to one of the arms of the bell-crank lever 12. On the said
lever 12 is a pall 17, engaging with the teeth of the ratchet wheel 13, and on
the lever 15 is a pall 18 engaging with the teeth of the ratchet wheel 14. By
the motions of the excentric 10, connecting rod 11, lever 12, connecting rod 16,
and arm or lever 15, the palls 17, 18, are made to push round the ratchet
wheels 13, 14, and thereby to give the necessary intermittent motions to the
two pairs of rolls e and f. The distance between each pair of rolls is adjusted
by means of the spring 20 acted upon by the screw nut or box 21, to which
it is connected. In order to prevent the scrap metal from sticking to the
punches when they make their return motions, I place immediately in front
of the fixed hollow dies i a plate or releaser marked 22, in Figure 5; this
releaser 22, is omitted in the other Figures, as its position obscures and
conceals more important parts. The said releaser has three holes 23, in it
of the size of the punches 7. On the retiring of the punches 1.if the scrap
metal should stick thereto it is removed by coming against the plate or
releaser 22. Instead of placing the parts of the machine horizontally, as in
the machine represented in the Drawings, the said parts may be situated in a
vertical plane. The punches in this case rise and fall vertically, and operate
upon the sheet metal situated in a horizontal plane.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do not
limit myself to the precise details herein described and illustrated in 'the
Drawings, as the same may be varied without departing from the nature of
my Invention; but I claim as my Invention the improvements in machinery
for coining, herein-before described and illustrated in the accompanying
Drawings, that is to say, arranging or combining substantially in the manner
described and illustrated the parts of machinery for coining, so that the

page_text: cutting out of the blanks and the milling or marking of their edges are effected
in the same machine.
In witness whereof, I, the said John Abraham, have hereunto set my
hand and seal, this Seventeenth day of October, in the year of our
Lord One thousand eight hundred and sixty-four.

RICHARD SKERRETT,
Clerk to George Shaw,
