PROVISIONAL SPECIFICATION.
New or Improved Machinery for the Manufacture of Hair Pins.
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 invention has reference to those parts of machines used in the manufacture
of hair pins by which the feeding, cutting off and pointing of the wires, which on
being afterwards bent form hair pins, is effected.
The new or improved machinery constituting my invention is constructed
essentially as follows. The wire after being drawn through the ordinary
straightening appliance is by an intermittent motion fed into the machine. The
said intermittent motion is effected by a connecting rod operated by an adjustable
crank pin on a crank plate fixed on a rotating axis. The length of the feed is
determined by the position of the crank pin on the crank plate. The said
connecting rod gives a to and fro motion to a slide, between which and a gripper
the wire is gripped on the advance motion of the slide. The gripping action is
effected by a lever the long arm of which is at the required times raised by a cam
on the rotating shaft referred to. The short arm of the said lever being depressed'
on the gripper causes the wire to be gripped on the advance motion of the slide.
On the return motion of the slide the cam permits of the descent. of the long arm
of the lever and the wire being no longer gripped remains stationary during the
return motion of the slide.
The advancing wire crosses the summit of a compound rotating disc having the
construction hereinafter described. The wire having advanced the required
distance, a piece of the arranged length is cut off, by a cutter operated by the
rotating shaft described. The cut off length of wire is pressed by a spring finger
rising and falling with the cutter upon the rotating disc described and is carried by
the said disc to the "mills" or rotating grinders by which its two ends are pointed,
the required rotary motion being at the same time given to the wire.

The compound rotating disc by which the cut off wire is carried to the "mills
and at the same time is made to rotate is constructed as follows. The said disc,
the axis which is at right angles to the shaft by which the feeding is effected, is
situated immediately in advance of the cutting off tools and the cut off length of
wire is situated between the periphery of the disc and the spring finger, The said
rotating disc consists of two parts; namely, a middle and two outer parts. The
two outer parts are fixed upon the shaft and partake of the slow rotary motion of
the said shaft. The middle part which is of larger diameter than the outer part
is toothed at its middle and turns freely on the shuft. A rotating pinion gearing
with the teeth of the middle part of the disc gives to the said middle a rotary
motion at a different speed than that of the outer parts fixed to the shaft. The
two outer edges of the inner or middle disc have equidistant cross slots or notches
made in them of a size suitable for the reception of the cut off length of wire, and
the cut off length of wire is pressed into a pair of these notches, one in each of
the edges of the inner or middle disc. The wire by the rotation of the disc is
carried down to the "mills" situated near the lowest point of the disc. Spring
metallic bands situated at the descending side of the disc support the ends of the
length of wire. The middle part of the wire bears upon cylindrical portions of

page_text: the middle part of the disc while its ends bear on cylindrical parts of the outer
discs. As the rate of rotation of the parts supporting the ends and middle of the
wire respectively differs, the wire in being carried down to the "mills" has a
rolling or rotary motion communicated to it; and on reaching the two rotating
mills, situated on opposite sides of the disc, the ends of the rotating wire are
pointed by the rotating "mills" against which they are brought. By the further
motion of the disc the pointed wire passes the end of the spring bands described
and being no longer supported falls into that part of the machine by which it is
doubled.

New or Improved Machinery for the Manufacture of Hair Pins.
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 my
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has reference to those parts of machines used in the manufacture
of hair pins by which the feeding, cutting off and pointing of the wires, which on
being afterwards bent form hair pins, are effected.
The new or improved_machinery constituting my invention is constructed
essentially as follows: The wire after being drawn through the ordinary
straightening appliance is by an intermittent motion fed into the machine. The
said intermittent motion is effected by a connecting rod operated by an adjustable
crank pin on a crank plate fixed on a rotating axis. The length of the feed is
determined by the position of the crank pin on the crank plate. The said
connecting rod gives a to and fro motion to a slide, between which and a gripper
the wire is gripped on the advance motion of the slide. The gripping action is
effected by a lever the long arm of which is at the required times raised by a cam
on the rotating shaft referred to. The short arm of the said lever being depressed
on the gripper causes the wire to be gripped on the advance motion of the slide.
On the return motion of the slide the cam permits of the descent of the long arm
of the lever and the wire being no longer gripped remains stationary during the
return motion of the slide.
The advancing wire crosses the summit of a compound rotating disc having the
construction hereinafter described. The wire having advanced the required
distance, a piece of the arranged length is cut off by a cutter operated by the
rotating shaft described. The cut off length of wire is pressed by a spring finger
rising and falling with the cutter upon the rotating disc described and is carried by
the said disc to the "mills" or rotating grinders by which its two ends are pointed,
the required rotary motion being at the same time given to the wire.
The compound rotating disc by which the cut off wire is carried to the "mills"
and at the same time is made to rotate is constructed as follows. The said disc,
the axis of which is at right angles to the shaft by which the feeding is effected, is
situated immediately in advance of the cutting off tools and the cut off length of
wire is situated between the periphery of the disc and the spring finger. The said
rotating disc consists of three parts, namely a middle or inner and two outer parts.
The two outer parts are fixed upon the shaft and partake of the slow rotary motion
of the said shaft. The middle part which is of less diameter except at its edges,
than the outer parts is toothed at its middle and turns freely on the shaft.

page_text: A rotating pinion gearing with the teeth of the middle part of the disc gives to
the said middle a rotary motion at a different speed than that of the outer parts
fixed to the shaft. The two outer edges of the inner or middle disc have equidistant
cross slots or notches made in them of a size suitable for the reception of the cut
off length of wire, and the cut off length of wire is pressed into a pair of these
notches, one in each of the edges of the inner or middle disc. The wire by the
otation of the disc is carried down to the "mills" situated near the lowest point
of the disc. Spring metallic bands situated at the descending side of the disc
support the ends of the length of wire. The middle part of the wire bears upon
the bottom of the notches in the middle part of the disc while its ends bear on the
cylindrical outer dises. As the rate of rotation of the parts supporting the ends
and middle of the wire respectively differs, the wire in being carried down to the
"mills" has a rolling or rotary motion communicated to it, and on reaching the two
rotating "mills," situated on opposite sides of the disc, the ends of the rotating
wire are pointed by the rotating "mills" against which they are brought. By the
further motion of the disc the pointed wire passes the end of the spring bands
described and being no longer supported falls into that part of the machine by
which it is doubled.
Figure 1 of the accompanying drawings represents in plan, Figure 2 in side
elevation, partly in section and Figure 3 in vertical section, ou the line a, .c
Figure 1, machinery for the manufacture of hair pins constructed according to my
invention. Figure 4 represents a portion of the compound carrier disc and
parts connected with it, in section detached, from the machine.
The same letters of reference indicate the same parts in the several figures of
the drawings.
a is the principal shaft of the machine driven by beit gearing from the driving
shaft. From the shaft a the principal working parts of the machine are operated
in the manner hereinafter described.
The
The feeding of the wire and the cutting off of the said wire into the required
lengths are effected as follows:-On the principal shaft a, is a crank plate a³
attached to which, by an adjustable crank pin d, is a connecting rod e. The other
end of the connecting rod e is fixed to a dovetail slide working on the bed of the
machine. Pivotted to this slide is a lever g, g' the short army of which actuates
the moveable jaw of the gripper 4, the long arm of the said lever resting on the
cam a³ on the principal shaft a. g is the pin on which the lever g, g' turns.
end of the arm g' of the gripping lever is maintained upon the cam a³ by a weight
or spring. When the connecting rode has made its backward stroke, the cam a³
raises the long arm g' of the lever g, gl and effects the gripping of the wire i. On
the advance or return stroke of the said connecting rod e into the position
represented in Figure 2 the gripped wire is drawn through the ordinary straightening
appliance and a length of the said wire sufficient to form the hair pin to be made
is fed onto the compound carrier disc 12, 1, 12. The length of the wire fed into the
machine is determined by the position of the adjustable crank pin d in the slot a
(see Figure 2) of the crank plate a. The length of wire fed onto the compound
disc, l, is cut off by means of the cutter m carried by the arm m¹ fixed to the
shaft m which shaft has the required angular motion given to it by a face cam a
on the principal shaft a bearing against the roller m³ on the arm m keyed to the
end of the said shaft m'. The roller m³ is kept to its bearing against the face
cam a by the spring n one end of which is fixed to a prolongation m of the
arm m; the other end being secured to the frame of the machine at p (see
Figure 1).
The compound carrier disc 12, 1, 12, a portion of which is represented in vertical
section in Figure 4, is made up of two cylindrical outer discs 1', keyed to the
shaft which is driven from the principal shaft a in the manner hereinafter
described and an inner disc turning loosely on the shaft q. The middle portion
of the inner disc is toothed and its edges have flanges 1, P. The said flauges l,
have equi-distant slots or notches for the reception of the cut off lengths of wire

page_text: fed into the machine, the parts of the wires beyond the notched flanges of the
inner disc resting on the cylindrical outer discs 1, 1. The wires are pressed into
the notches of the inner disc by the spring fingers which is carried by the cutter
arm m (see Figure 3).
q
The shaft and the inner toothed portion of the compound disc 1, 1, are
driven by the toothed wheels c' and c respectively the said toothed wheels being
situated on the shaft c. The toothed wheel gears with the toothed wheel q' on
the shaft while the toothed wheel gears directly with the disc 7 (see Figure 1).
The shaft c is driven by the worm a on the principal shaft a gearing with the
worm wheel on the end of the shaft (see Figure 3). By the arrangement
described of the gearing the outer cylindrical discs 12, 12 are rotated at a greater
speed than the inner disc 1. By the action of the said outer discs 12, the
wires which are carried, by the notched disc l, to the rotary grinding mills r, 1',
have a rotary or rolling motion communicated.to them. By the action of the said
grinding mills r, and the rotary motion of the wires referred to the ends of the
said wires are pointed.
The wires are retained in position in the notches and in contact with the outer
cylindrical discs 1, 1 by the metallic bands t, t't on the descending side of the
compound carrier disc. The position of the wire after it has been carried down
by the compound carrier disc and its ends brought in contact with the grinding or
pointing mills r, is indicated in dotted lines in Figure 2, and the manner in which
the bands t, t, t maintain the cut off wires in place on the compound carrier disc
is best seen in Figure 4. When the pointed wires pass beyond the metallic
retaining bands on the ascending side of the carrier disc 1, 1, they fall from the
said disc into the doubling or bending mechanism of the machine which is not
represented as it constitutes no part of my present invention.
Having described the construction and action of the several parts of the machine
1 remark that the several operations take place in the following order. The
feeding slide having come to the end of its back stroke the gripper his operated
and the wire is seized and drawn on the return or forward motion of the slide
through the straightening appliance k into the machine. The length of wire fed
into the machine is cut off and pressed into the notches of the compound carrier
disc, 1, while the slide f is making its next back or non-feeding stroke. By
the rotary motion of the compound carrier disc the series of wires fed onto it are
carried in succession to the grinding mills r,r where the ends of the wires are
pointed in the manner herein before described. On passing from the grinding
inills, the pointed wires fall one by one into the bending or doubling mechanism
of the machine.
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 of "New or improved machinery for the manufacture of hair
pins":
