Improvements in or connected with Metallic Fasteners for Fixing
Buttons to Fabric, Leather, or the like, and in Apparatus
therefor.
We, CHRISTEN REES BONNE, Patent Agent and EDWARD KENNEDY,
Solicitor, both of 57 & 58 Chancery Lane, London do hereby declare the nature
of this invention to be as follows:-
In fixing buttons by means of a metallic fastener machines similar to eyeletting
machines are usually employed, in which one die causes the fastener to be deflected
and bent around some part of the button.
Our invention refers to the metallic fastener, to the construction of the die on
which the fastener is placed and to the means employed for holding the button
during the operation.
According to our invention a fastener may be made from suitable wire by twisting
and bending it so as to take the shape of a large headed nail or staple, but an
ordinary nail or headed staple may also be employed and the head may be eccentric
or otherwise relatively to the stalk.
In machines for fastening buttons by means of a metallic fastener the die which
receives the fastener is usually surrounded by a receding cylinder, controlled by a
spring. For the purposes of our invention the same arrangement is employed but
the receding cylinder is provided with a guide for the stalk or stalks of the fastener
such guide being arranged so as to permit of the fastener head being dropped into
the cylinder while the stalk can be inserted and withdrawn from the guide in an
horizontal direction. With this end in view the guide may take the shape of a
plate slotted to a point which is in the line of the stalk when the head rests on the
die. A slot is likewise formed between the guide plate and the rim of the cylinder
in about half its periphery and in a perpendicular direction relatively to the slot in
the plate so that by these means the fastener may be passed sidewise (the head
under the plate and the stalk in the slot of the plate) into the cylinder. The stalk
is thus guided on all sides except the one of the slot. It is obvious that the guide
plate does not require to be the full circumference of the cylinder so long as there
is sufficient substance to form a guide for the stalk.
When a washer is employed in connection with the fastener such washer takes
the place of the guide plate, being lodged in a recess made in the top of the
receding cylinder. In order to prevent such washer from slipping out of the recess
before the fastener has been thrust fully home, I provide the recess with a lip or
stop on the side opposite the direction in which the stalk is being bent.
The upper die, which is provided with well known means for bending and
deflecting the metallic fastener employed, is furnished, according to our invention,
with certain contrivances for holding the button in position during the operation.
Now having particular reference to hole buttons such as are commonly used for
trousers and more especially the kind with two holes and an oval indentation (the
neck of the button) we take a metal plate in which we form a notch of a shape that
corresponds to the indentation of the button, which can therefore rest on the plate
by the rim. The plate we fix under a sleeve which can move up and down on the
die plunger, guided by a slot and pin, to the extent at least of the overall thickness
of a button. When at rest the sleeve by its own weight or assisted by a spring or
otherwise, drops as far as the guide pin and slot will permit and the button can
then be pushed into the notch, the oval shape of which and of the indentation
causing the button to be seated in the proper position. When now the plunger is
brought down against the lower die, the sleeve with plate and button is forced

page_text: upwards until the button comes against the die. When the plunger is again
raised, the sleeve drops and the button, now connected with the fastener can be
withdrawn.
The plate, which forms the seat for the button as described may also be attached
to, or form part of, a bow shaped spring fastened to the plunger or die and arranged
in such a way that the notch is directly under the die the tendency of the spring
being to force it against same.

Improvements in or connected with Metallic Fasteners for Fixing
Buttons to Fabric, Leather, or the like, and in Apparatus
therefor.
We CHRISTEN REES BONNE Patent Agent and EDWARD KENNEDY Solicitor
both of 57 & 58 Chancery Lane London do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
In fixing buttons by means of a metallic fastener machines similar to eyeletting
machines are usually employed in which one die causes the fastener to be deflected
and bent around some part of the button.
Our invention refers to the metallic fastener to the construction of the die on
which the fastener is placed and to the means employed for holding the button
during the operation.
The manner in which we prefer to carry our invention into effect is shewn by the
accompanying drawings in which
Fig. 2 is a cross section of the die in which the fastener is placed and Fig. 1 is a
cross section through upper die shewing the means of holding the button during
operation,
Fige. 3 & 4 are top view and section respectively of a form of fastener and
Fig. 5 shews a detail.
According to our invention a fastener may be made from suitable wire by
twisting and bending it so as to take the shape of a large headed nail or staple as
shewn in Figs. 3 & 4 but an ordinary nail or headed staple may also be employed,
and the head may be eccentric or otherwise relatively to the stalk.
l
In machines for fastening buttons by means of a metallic fastener the die which
receives the fastener is usually surrounded by a receding cylinder controlled by a
spring. For the purposes of our invention the same arrangement is employed but
the receding cylinder is provided with a guide for the stalk or stalks of the
fastener such guide being arranged so as to permit of the fastener head being
dropped into the cylinder while the stalk can be inserted and withdrawn from the
guide in an horizontal direction. With this end in view the guide may take the
shape of a plate slotted to a point which is in the line of the stalk when the head
rests on the die. A slot m is likewise formed between the guide plate and the rim
of the cylinder in about half its periphery and in a perpendicular direction
relatively to the slot in the plate so that by these means the fastener may be
passed sidewise (the head under the plate and the stalk in the slot of the plate)
into the cylinder. The stalk is thus guided on all sides except the one of the slot.
It is obvious that the guide plate does not require to be the full circumference of
the cylinder so long as there is sufficient substance to form a guide for the stalk.
When a washer is employed in connection with the fastener such washer takes
the place of the guide plate being lodged in a recess made in the top of the receding
cylinder. In order to prevent such washer from slipping out of the recess before

page_text: the fastener has been thrust fully home I provide the recess with a lip p or stop on
the side opposite the direction in which the stalk is being bent.
The upper die which is provided with well known means for bending and
deflecting the metallic fastener employed is furnished according to our invention
with certain contrivances for holding the button in position during the operation.
Having reference to hole buttons we may employ a holder for the buttons of the
construction shewn in Fig. 1. fis the die with curve, x is a sleeve which can move
up and down on the plunger m which the die f is fixed, set screw Z and slot Z' in
the plunger regulating the extent of the up and down movement of the sleeve x.
To the bottom of sleeve x is fixed a plate y having a notch y' which corresponds in
size and in shape with the indentation of a hole button. In operation the button is
placed on plate y, the indentation fitting in notch y'. When the indentation is
oblong, having only two holes, these naturally come directly under the curve.
forcing the upper and lower die together, the sleeve a is moved upwards until the
indentation of the button is in contact with the die, when the fastener point, enters
through one hole, strikes the curve bends over and issues by the second hole, as
before. When the dies separate the sleeve a drops and the fastened button may
thus be removed.
On
When the plunger is again raised the sleeve drops and the button now connected
with the fastener can be withdrawn.
The plate which forms the seat for the button as described may also be attached
to or form part of a bow shaped spring fastened to the plunger or die and arranged
in such a way that the notch is directly under the die the tendency of the spring
being to force it against same.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I hereby declare that what
I claim is :-
1. In apparatus for fastening buttons a slotted plate / acting as guide for the
stalk of fastener, substantially as described.
sub-
2. In apparatus for fastening buttons the means for holding the buttons in
position during the operation consisting in a sleeve x with notched plate
stantially as described.
3. In apparatus for fastening buttons the lip p (Fig. 5) overhanging the recess
for washer substantially in the manner as and for the purpose described and shewn
in the drawings.
