Method of and Apparatus for Making Stud Buttons with Jointed
Heads or Front Plates.
I,,NOAH MITCHELL of 194 Regent Street, near Oxford Street, in the County of
London, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention has for object, the construction and arrangement of various dies,
templates, gauges and other appliances affixable to a press head or heads and bed
plates for,
1. To cut a blank from a strip or sheet of metal, the blank so cut or stamped being
of ring shape with a comparatively wide bar across it.
2. To an arrangement of cutters for splitting the wide cross bar lengthwise, and
separating them into two distinct legs.
3. To an appliance for turning the two legs or posts at right angles and giving
simultaneously a rounded formation to both faces of the ring.
4. To a hammer or tapper appliances for thinning down and elongating the two
legs, or posts.
5. To pressure dies for curving the legs, so that their ends are caused to approach
each other and simultaneously kinking the extreme ends to form pins, onto which the
front plate or top may be pivotted.
6. To a stamp for cutting the front blank with two lips from a strip or sheet
of metal.
7. To a die for dishing the front plate or top and pressing inwardly the edge
thereof and simultaneously bending the two lips upwards.
8. To an appliance for heading up or thickening the two lips and forming recesses
on the inner faces to serve as means for locking the front plate in either of three
positions to which it can be turned, the two legs of the ring or back plate yielding
when the shoulders next the recesses of the lips are moved in contact with them.
It will be observed that by my invention, the whole of the parts are prepared
and fashioned by dies and other tools from two pieces of metal and that no solder
is used.
My invention will be more clearly understood by the following description when read
in connection with the annexed drawings.
Figure 1 is a view of a strip of metal A from which a blank B shown at Figure 2
has been cut by the double punch or die, seen at Figure 3. One of these punches
is formed with two arch shaped dies C, C, for forming the holes D, D, in the strip A
and leaving a kind of cross bar E in the blank. F is the second die for punching
the blank from the strip.
In Figure 3, I have shown the two dies C, F, on the same stock G because
their action is continuous in succession but they may be on separate stocks, if
desired.
Figure 4 represents the die composed of two cutters H, H, with angled faces
and set in opposite directions in the same stock I, and J is the matrix similarly
formed for acting in conjunction with the cutters H, H, for severing the cross bar E,
as indicated at Figure 5, these two pieces when bent at right angles by the die K
and matrix L, Figure 6, constitute the legs M, M, as seen at Figure 7.
The die K and matrix L have shaped shoulders and sufficient pressure is exerted
to swage or squeeze the ring portion of the blank which up to this operation has
square edges into a shape approximating an oval, as seen at Figure 7.
The blank thus far made is arranged in a matrix N on its side, as in the plan
and sectional side views Figures 8 and 9, the legs M, M, being half embedded in
tapered grooves, as indicated, and within which by a tapping action of a similarly

page_text: shaped top die, not shown, or it may be gradual pressure of the top die, the legs are
elongated to the desired length. The article is then placed ring downwards in
another matrix P, see Figure 10, a block Q in two parts is used on this matrix,
as will be understood by the plan view, Figure 12. Each part a, b, is pivotted
on the bottom die P and as their outer ends c, d, are moved towards each other,
the legs M, M, which engage in the grooves e, f, are pressed in to bear against
the corresponding grooves, h, formed in the sides of the stem of the bottom
die P, the end c, d, being then locked by the catch; taking round the pink. The
roughness of the edges of the legs during this is gradually reduced until they
become smooth. The top portion of the block Q is hollow and the ends of the
legs project, as seen at Figure 10. These projecting ends are then pressed outwards,
as shown in dotted lines and on the descent of the upper die, they become kinked,
and leave the article, as indicated at Figure 11, the two outspread portions serving
as axles on which the head can be folded.
The head blank R is stamped from a strip to a shape shown at Figure 13 with
two ears S, S, and then by the upper and lower dies T, U, seen at Figure 14, the
blank is caused to assume the cup shape, Figure 15, the ears S, S, being bent up
at right angles to the base. The cup shaped blank next placed inverted upon the
lower die V, Figure 16, into which the ears are lightly sprung, so that when the
upper die W is brought down into contact, the ears and the edge of the cup are
squeezed inwards along the holes X, X, of the lower die which causes the edge of the
cup to curve inwards sufficiently for the next operation, namely, to be curled between
the dies Y, Y, as indicated at Figure 17, at which process the ears are compressed
and thickened and made ready for angled notches to be formed at three portions of
their inner faces by the appliance shown at Figure 18 consisting of a bed plate
recessed to the shape of the head R, so that the ears S, S, project upward beyond the
top face of the bed to be covered by a fold over plate Z in holes of which the ears
are held firmly.
The fold over plate Z carries a couple of plates Z, Z, having V cutters on their
outer faces and on these plates being driven apart by a tool forced into a central hole,
the V shaped cutters are pressed into the legs S, S, to form the notches seen at
Figures 19 and 20.
A hole of the size of the axles of the legs shown at Figure 11 is then made
through the two ears S, S, for easy connection of the legs as pivots on which the
head can be folded almost flat with the legs for being easily passed through ordinary
holes of a shirt neckband and a collar, the head being temporarily held in the required
position by the edges of the legs springing into the horizontal V notches at the side
of the ear, whether the head be folded to the right, or to the left of the legs, and when
the head is folded up as the head proper of a stud, the edges of the legs engage in the
vertical notches of the ears and fixes it in that position, or until a side pressure is
exerted to overcome the grip of the legs in the notches.

COMPLETE SPECIFICATION.
Method of and Apparatus for Making Stud Buttons with Jointed
Heads or Front Plates.
I, NOAH MITCHELL of 194 Regent Street, near Oxford Street, in the county of
London, Manufacturer 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 stateinent :-
This invention has for object the construction and arrangement of various dies,
templates, gauges and other appliances affixable to a press head or heads and bed
platos for

page_text: 1. To cut a blank from a strip or sheet of metal, the blank so cut or stamped being
of ring shape with a comparatively wide bar across it.
2. To an arrangement of cutters for splitting the wide cross bar lengthwise and
separating them into two distinct legs.
3. To an appliance for turning the two legs or posts at right angles and giving
simultaneously a rounded formation to both faces of the ring.
4. To a hammer or tapper appliances for thinning down and elongating the two legs
or posts.
5. To pressure dies for curving the legs so that their ends are caused to approach
each other and simultaneously kinking the extreme ends to form pins on to which the
front plate or top may be pivotted.
6. To a stamp for cutting the front blank with two lips from a strip or sheet of
metal.
7. To a die for dishing the front plate or top and pressing inwardly the edge thereof
and simultaneously bending the two lips upwards.
8. To an appliance for heading up or thickening the two lips and forming recesses
on the inner faces to serve as means for locking the front plate in either of three
positions to which it can be turned, the two legs of the ring or back plate yielding
when the shoulders next the recesses of the lips are moved in contact with them.
It will be observed that by my invention the whole of the parts are prepared and
fashioned by dies and their tools from two pieces of metal and that no solder is
used.
My invention will be more clearly understood by the following description when
read in connection with the drawings accompanying my Provisional Specification.
Figure 1 is a view of a strip of metal A from which a blank D shown at Figure 2.
has been cut by the double punch or die, seen at Figure 3. One of these punches is
formed with two arch shaped dies C, C, for forming the holes D, D, in the strip A and
leaving a kind of cross bar E in the blank. F'is the second die for punching the
blank from the strip.
In Figure 3 I have shown the two dies C, F, on the same stock G because their
action is continuous in succession but they may be on separate stocks, if
desired.
Figure 4 represents the die composed of two cutters H, H, with angled faces and
set in opposite directions in the same stock I, and J is the matrix similarly formed for
acting in conjunction with the cutters H, H, for severing the cross bar E, as indicated
at Figure 5, these two pieces when bent at right angles by the die K and matrix L
Figure 6, constitute the legs M, M, as seen at Figure 7.
The die K and matrix L have shaped shoulders and sufficient pressure is exerted to
swage or squeeze the ring portion of the blank which up to this operation has square
edges into a shape approximating an oval, as seen at Figure 7.
The blank thus far made is arranged in a matrix N on its side as in the plan and
sectional side views Figures 8 and 9, the legs M, M, being half embedded in tapered
grooves, as indicated, and within which by a tapping action of a similarly shaped top
die, not shown, or it may be gradual pressure of the top die, the legs are elongated to
the desired length. The article is then placed ring downwards in another matrix P,
see Figure 10, a block Q in two parts is used on this matrix, as will be understood by
the plan view Figure 12. Each part a, b, is pivotted on the bottom die P and as their
outer end c, d, are moved towards each other, the legs M, M, which engage in the
grooves e, f, are pressed in to bear against the corresponding grooves g, h, formed in
the sides of the stem i of the bottom die P, the ends c, d, being then locked by the
catch taking round the pin k. The roughness of the edges of the legs during this is
gradually reduced until they become smooth. The top portion of the block Q is
hollow and the ends of the legs project, as seen at Figure 10. These projecting ends
are then pressed outwards as shown in dotted lines and on the descent of the upper die,
they become kinked, and leave the article as indicated at Figure 11, the two outspread
portions serving as axles on which the head can be folded.
The head blank R is stamped from a strip to a shape shown at Figure 13 with two

page_text: ears S, S, and then by the upper and lower dies T, U, seen at Figure 14, the blank is
caused to assume the cup shape, Figure 15, the ears S, S, being bent up at right
angles to the base. The cup shaped blauk is next placed inverted upon the lower
die V, Figure 16, into which the ears are lightly sprung, so that when the upper
die W is brought down into contact, the ears and the edge of the cup are squeezed
inwards along the holes X, X, of the lower die which causes the edge of the cup to
curve inwards sufficiently for the next operation, namely, to be curled between the
dies Y, Y, as indicated at Figure 17, at which process the ears are compressed and
thickened and made ready for angled notches to be formed at three portions of their
inner faces by the appliance shown at Figure 18 consisting of a bed plate recessed to
the shape of the head R so that the ears S, S, project upward beyond the top face of
the bed to be covered by a fold over plate Z in holes of which the ears are held
firmly.
• The fold over plate Z carries a couple of plates Z', Z', having ✓ cutters on their
outer faces and on these plates being driven apart by a tool forced into a central hole,
the shaped cutters are pressed into the legs S, S, to form the notches seen at
Figures 19 and 20.
A hole of the size of the axles of the legs shown at Figure 11 is then made through
the two ears S, S, for easy connection of the legs as pivots on which the head can be
folded almost flat with the legs for being easily passed through ordinary holes of a
shirt neckband and a collar, the head being temporarily held in the required position
by the edges of the legs springing into the horizontal V notches at the side of the
ear, whether the head be folded to the right, or to the left of the legs and when the
head is folded up as the head proper of a stud, the edges of the legs engage in
the vertical notches of the ears and fixes it in that position or until a side pressure is
exerted to overcome the grip of the legs in the notches.
In the drawings, B, is identified as a ring but when a flat or solid kind of base is
required a shell of thin metal or other material may be secured thereto and the head
may have a stone, a diamond, an enamelled or other mounting fitted to it.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The manufacture of a stud button from two pieces of metal and capable of being
jointed one to the other, the head being foldable against the legs of the base in the
manner and for the purposes set forth.
2. The construction and employment of the various appliances shewn on the
drawings accompanying my Provisional Specification Figures 3, 4, 5, 6, 7, 8 10
and 12 whereby by a succession of operations the bottom and legs of the stud base can
be-manufactured ready for the attachment of a bead as described.
3. The construction and employment of the various appliances shewn on the
drawings accompanying my Provisional Specification Figures 14, 16, 17 and 18
whereby by a succession of operations a head can be manufactured for a stud and
jointable thereto for folding pnrposes as set forth.
