PROVISIONAL SPECIFICATION.
A New or Improved Machine for Bending Wires in the Manufacture
of Hair Pins and Staples, and for other like purposes.
I, RICHARD RIDEOUT BEARD, Managing Director of Kirby, Beard & Co.
Limited, of Ravenhurst Works, Bradford Street, Birmingham, in the County of
Warwick, Pin and Needle Manufacturers do hereby declare the nature of this
invention to be as follows:-
:-
My said invention consists of a machine the parts of which are constructed and
arranged and operate in the manner hereinafter described.
I will describe my invention in connection with the -bending of a wire in the
manufacture of a hair pin.
On the bed of the machine is a dovetail slide working in an undercut or dovetail
in the bed of the machine. This slide has a reciprocating or to and fro motion
communicated to it preferably by a lever and cam. At about the middle of the
said slide and on its upper face two arms are jointed the said arms being capable
of turning on their joints in a horizontal plane. The rear short ends of the said
arms are connected by a coiled spring which tends to draw them together and
consequently to open the fore or longer parts of the said arms. On the bed of the
machine and near that end at which the bending of the wire is effected, and which
end I will hereinafter call the fore, are two adjustable upright projections or stops
between which the fore ends of the said arms pass as the slide is completing its
advance motion. The fore ends of the said arms are so inclined on their outer sides
that on passing between the said stops the said ends are pressed inwards so as to
approach within a short distance of each other. A bracket on the bed of the
machine carries a fixed depending pin round which the bending of the wire is
effected. When the slide has nearly reached the end of its stroke the fore ends
of the arms described pass a short distance beyond the said pin on either side
respectively. At the fore end of the machine and at a higher level than the
ends of the arms is an incline down which the wires to be bent are fed horizontally
between two guides. The wire is arrested before it reaches the bottom of the said
incline by two fingers which support it near its ends. These fingers are carried by
a horizontal axis to which by means of a lever attached to the said axis a slight
angular motion can be given. When the end of the said lever is slightly raised
the wire no longer supported by the fingers falls upon two small supporting
brackets. The wire is now immediately behind and its middle is in contact with
the depending pin hereinbefore referred to. The slide on the reversal of its
motion brings the turned up ends of the arms against the wire and by its further
motion bends the wire on the said depending pin. On the further retiring motion
of the slide the fore ends of the arms passing from between the projections or stops
which close them open by the action of the coiled spring described and the bent
wire being no longer supported falls through an opening in the bed into a receptacle
placed for its reception. The lever by which the fingers supporting the wire near
the bottom of the incline are operated is raised at the required time by a fixed stop
on the slide advancing under the inclined end of the said lever.
From the foregoing description it will be understood that the several operations
of the machine succeed each other in the following order.
The slide being in its withdrawn position the fed in wire is supported by the
fingers described the slide advancing the fore ends of the arms approach each other
and pass under the wire. The fingers which supported the wire being withdrawn
the wire falls upon the small brackets described. The slide performing its return

page_text: motion the turned up ends of the arms bend the wire at its middle on the depending
pin into the required shape. The ends of the arms on retiring from between the
stops which press them towards each other open by the action of the coiled spring
and the unsupported bent wire falls from the machine into a receptacle placed for
its reception.
The application of my invention to the bending of wires in the manufacture of
staples and for other like purposes differs in no essential respect from its application
to the bending of wires in the manufacture of hair pins as hereinbefore described.

COMPLETE SPECIFICATION.
A New or Improved Machine for Bending Wires in the Manufacture
of Hair Pins and Staples, and for other like purposes.
I, RICHARD RIDEOUT BEARD, Managing Director of Kirby, Beard & Co.
Limited, of Ravenhurst Works, Bradford Street, Birmingham, in the County of
Warwick, Pin and Needle Manufacturers, 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 :-
My said invention consists of a machine the parts of which are constructed and
arranged and operate in the manner hereinafter described.
I will describe my invention in connection with the bending of a wire in the
manufacture of a hair pin.
On the bed of the machine is a dovetail slide working in an undercut or dovetail
in the bed of the machine. This slide has a reciprocating or to and fro motion
communicated to it preferably by a lever and cain. At about the middle of the
said slide and on its upper face, two arms are jointed the said arms being capable
of turning on their joints in a horizontal plane. The rear short ends of the said
arms are connected by a coiled spring which tends to draw them together and
consequently to open the fore or longer parts of the said arms. On the bed of the
machine and near that end at which the bending of the wire is effected, and which
end I will hereinafter call the fore end, are two adjustable upright projections or
stops between which the fore ends of the said arms pass as the slide is completing
its advance motion. The fore ends of the said arms are so inclined on their outer
sides that on passing between the said stops the said ends are pressed inwards so as
to approach within a short distance of each other. A bracket on the bed of the
inachine carries a fixed depending pin round which the bending of the wire is
effected. When the slide has nearly reached the end of its stroke the fore ends of
the arms described pass a short distance beyond the said pin on either side
respectively. At the fore end of the machine and at a higher level than the ends
of the arms is an incline down which the wires to be bent are fed horizontally
between two guides. The wire is arrested before it reaches the bottom of the said
incline by two fingers which support it near its ends. These fingers are carried by
a horizontal axis to which by means of a lever attached to the said axis a slight
angular motion can be given. When the end of the said lever is slightly raised
the wire no longer supported by the fingers falls upon two small supporting
brackets. The wire is now immediately behind and its middle is in contact with
the depending pin bereinbefore referred to. The slide on the reversal of its
motion brings the turned up ends of the arms against the wire and by its further
motion bends the wire on the said depending pin. On the further retiring motion
of the slide the fore end of the arms passing from between the projections or stops
which close them, open by the action of the coiled spring described and the bent
wire being no longer supported falls through an opening in the bed into a

page_text: receptacle placed for its reception. The lever by which the fingers supporting the
wire near the bottom of the incline are operated is raised at the required time by a
fixed stop on the slide advancing under the inclined end of the said lever.
From the foregoing description it will be understood that the several operations
of the machine succeed each other in the following order.
The slide being in its withdrawn position the fed in wire is supported by the
fingers described; the slide advancing the fore ends of the arms approach each
other and pass under the wire. The fingers which supported the wire being with-
drawn the wire falls upon the small brackets described. The slide performing its
return motion the turned up ends of the arms bend the wire at its middle on the
depending pin into the required shape. The ends of the arms on retiring from
between the stops which press them towards each other open by the action of the
coiled spring and the unsupported bent wire falls from the machine into a receptacle
placed for its reception.
Figure 1 of the accompanying drawings represents in side elevation, Figure 2 in
back, elevation and Figure 3 in plan, a machine for bending wires in the
manufacture of hair pins, staples and the like constructed according to my
invention;
Figure 4 represents the same partly in side elevation and partly in vertical
section, the section being taken on the line e, . Figure 2;
Figure 5 is a horizontal section of the said machine taken on the line y, y
Figure 4.
The same letters indicate the same parts in the several figures of the drawings.
a is the incline down which the wires bare fed, one by one, into the machine, the
said wires b being temporarily supported by the fingers c, c (see Figure 1) which
constitute the short arm of the bent lever c, c² turning on the pin or axis d. The
said fingers c, c are raised into the position represented in Figures 4 and 5 so as to
allow the wire to pass into the machine by the stop e coming under the rear end of
the long arm 2 of the lever c, 2 on the forward motion of the dovetail slide f to
which the said stop e is fixed.
The dovetail slide carries the arms or levers g,g which turn upon the pins or
centres h, h. The short arms of the said levers g, g are connected by the coiled
spring which tends to open the fore ends g², g2 of the said levers. The fore
ends, of the levers g, constitute raised or projecting parts on the ends of the
levers 9, 9.
On the forward motion of the slide f, that is, in the direction of the
arrow Figure 1, the fore ends 92, 2 of the levers g, 9 pass between the adjustable
pins or studs k, k on the bed of the machine and are thereby nearly closed as
represented in Figure 4. The forward and backward motion of the slide fare
effected by a lever and cam or other equivalent device not shewn in the drawings.
Situated midway between the pins or studs k, k is the depending pin / carried by
the bracket m. When the slide has completed its forward motion and the
fingers c, c have been raised by the stop e, the wire falls and is supported upon
the long arms of the levers g, g behind the raised or projecting fore ends g², g² and
in front of the depending pin 7 as represented in Figures 4 and 5, so that on the
back motion of the slide (that is, in the direction of the arrow in Figure 4) and
levers g,g the said fore ends g, y coming into contact with the wire b bends it at
its middle on the depending pin into a hair pin. On the fore ends g² g² passing
from between the pins or studs k, k the long arms of the levers y, open by the
action of the spring i and the bent wire being no longer held falls through the
opening into a receptacle under the bed of the machine.
μ
On the slide making another forward motion the operations hereinbefore described
are repeated upon another length of wire which has been fed into the machine in
the manner herein before described.
The application of my invention to the bending of wires in the manufacture of
staples and for other like purposes differs in no essential respect from its application
to the bending of wires in the manufa ture of hair pins as hereinbefore described
and illustrated in the accompanying drawings..

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that I claim
as my invention :-
The construction and combination or arrangement of parts herein before described
and illustrated in the accompanying drawings constituting a new or improved
machine for bending wires in the manufacture of hair pins, staples and the like,
the parts of the said machine consisting essentially of a dovetail slide working on
the bed of the machine, the said slide carrying wire bending arms or levers and a
stop for raising at the proper time the fingers which temporarily support the wire
to be bent in combination with adjustable pins or studs for closing the fore ends of
the levers on the forward motion of the alide and a fixed depending pin on which
the wire fed into the machine is bent substantially as herein before described and
illustrated.
