PETER MACQUAY, of Birmingham, in the County of Warwick, Machinist. NEW
OR IMPROVED MACHINERY FOR THE MANUFACTURE OF BUCKLE TONGUES."
My Invention consists of the construction and arrangements of parts herein-after
described, of machinery for the manufacture of buckle tongues, that is to say,
straight or curved wires or bars pointed at one end, and having a hook at the
opposite end, the said hook being closed upon the buckle frame.
The said machinery consists essentially of mechanism for feeding the length of
wire into the machine, for cutting off and holding the cut off length of wire, for
pointing the end of the wire, and for fashioning the hook on the said wire.
The parts of the said machinery are constructed, combined, and worked sub-
stantially as follows:-The wire from the coil is fed into the machine by a recipro-
cating slide, a lever on which slide grips the wire on making its advance stroke, and
releases the wire on making its back or return stroke. The wire is fed by the feeder
through a guide block of steel having a hole in it of the size of the wire. The
inner face of this steel block constitutes the fixed cutter. The length of wire fed
into the machine is held by a pair of gripping tools, one of the said tools being
stationary and the other moveable, the said moveable gripping tool also constituting
the moveable cutter by which the length of wire is cut off. By the advance of the
moveable gripping tool it cuts off the length of wire against the face of the steel
block through which it was passed, and grips the cut off length between itself and
the fixed gripping tool. The cut off length of wire is thus held firmly while the
subsequent operations are performed upon the end protruding from the said

page_text: gripping tools, the said end being of sufficient length to form the hook of the buckle
tongue.
The fashioning of the hook from the protruding end of the wire held in the
gripping tools is effected, first, by a pair of dies simultaneously approaching to and
receding from one another, and afterwards by a second die moving in a direction at
right angles to the said pair of dies in conjunction with a peg having a vertical
motion, around which the hook is finally bent.
One of the dies of the pair of dies has on its acting face a convex projection, and
the acting face of the other die has a corresponding concavity in it. By the simul-
taneous closing of these dies upon the protruding end of the gripped length of wire,
a bow or nearly semicircular figure is given to it. The pair of dies open or retire
from one another, and the vertical peg descends into the bow or semicircular bend
of the wire. The die situated at right angles to the pair of dies described now
advances, and bends the bow or semicircular bend around the peg, so as thereby to
form the hook of the buckle tongue. The last described die retires, the peg rises,
and the gripping tools open and release the buckle tongue which falls from the
machine.
The end of the buckle tougue is pointed either by compression between the
gripping and cutting off tools herein-before described, or by making the moveable
gripping tool point the end of the wire by a cutting or shearing operation. Or
the pointing of the buckle tongue may be effected by a grinding operation after
it leaves the machine.
The tools and dies herein-before described are shaped to suit the sectional figure
of the buckle tongues to be made, such as round, flat, or half round buckle
tongues.
The feeding slide is worked by a lever acted upon by a cam on the cam shaft of
the machine.
The
The moveable gripping tool and cutter is worked by a slide acted upon by a cam.
The first shaping dies are worked by a series of slides acted upon by cams.
second shaping die and the peg around which the hook is finally bent are worked
by levers acted upon by cams on the cam shaft.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which my Invention may be performed.
Figures 1 and 2 represent plans of the machine (the cover and springs being
removed in Figure 1); and Figure 3 is a side elevation of the same.
Figure 4 is a cross section partly in elevation of the machine taken on the line
A, B, Figure 1.
Figure 5 is a vertical section of a portion of the machine drawn to a larger scale
taken on the line C, C, of Figure 1.
Figures 6 and 7 are plans of a portion of the machine drawn to a larger scale, the
first pair of shaping dies being represented open in Figure 6, and closed in
Figure 7.
Figure 8 is a horizontal section of the first pair of shaping dies, and parts near
the said dies.
The same letters of reference indicate the same parts in the several Figures of
the Drawings.
a is the wire from which the buckle tongues are to be made, the said wire being
fed into the machine by the reciprocating dovetail slide b carrying the gripping
lever c.
When the gripping lever c is first acted upon by the secondary lever d
the wire a is gripped between its acting end, and the support e and the further
motion of the said lever d gives the advance motion to the slide b, and a length of
wire is fed into the machine through the tubular steel guide block f. When the
pressure is removed from the lever d the grip of the lever c is taken off the wire a,
and the slide b makes its back stroke by the action of the spring g. In front of
; the feeding slide b is a weighted lever for holding down and putting the required
pressure on the wire being fed to the machine. The wire is fed into the machine
between the pair of gripping tools i, k, and first pair of shaping dies l, m. The

page_text: tool is the moveable gripping tool, and the other tool k has a limited sliding
motion given to it by the action of the other tool i. The moveable tool i con-
stitutes the moveable cutter, and the face of the steel guide block f constitutes the
fixed cutter against which the length of wire is cut off. The said gripping tools
i, k, also point by compression between them the end of the wire from which a
buckle tongue is to be made.
The construction of the gripping and pointing tools i, k, is best seen in the
enlarged views, Figures 6, 7, and 8. By the advance of the moveable tool i it cuts
off the length of wire against the face of the steel block f and grips the cut-off
length between itself and the tool k, which said tool k has been slightly pushed
back to its abutment by the advancing tool i. The length of wire cut off by the
tool is by the action of the said tool i carried a little out of the line of the axis of
the machine, and the end of the cut-off length is compressed between the two
tools i, k, so as to point it. The parts of the two tools i, k, by which the pointing
of the end of the cut-off length is effected are marked 22, k², in Figure 8.
Instead of the two tools i, k, pointing the end of the wire by a compressing action,
the said tools or one of them may effect the pointing by a cutting or shearing
action by giving to the tools or tool the required shape. After the wire has been
cut off and its end pointed it is held firmly by the tools i, k, while the required
operations are performed on its protruding end, the said protruding end being of
sufficient length to form the hook of the buckle tongue. The fashioning of the hook
from the protruding end of the wire held in the gripping tools i, k, is effected by
the first pair of shaping dies l, m, and subsequently by the action of the die n in
conjunction with the vertical peg p around which the hook is finally bent. The
shaping die of the pair of dies l, m, has on its acting face a convex projection l³,
and the acting face of the other shaping die m has a corresponding concavity m³ in
it. The shaping dies l, m, are both moveable, and by the simultaneous closing of
the said dies upon the projecting length of wire a bow or nearly semicircular figure
is given to it, as represented in Figure 7, where the pair of shaping dies l, m, are repre-
sented closed upon the wire. The end of the wire having been thus partly shaped
the dies l, m, open or retire from one another, and the vertical peg p descends into
the bow-shaped end of the wire. The flat shaping die n which moves in a direction
at right angles to that in which the dies l, m, move next advances and bends the
bow around the peg p so as thereby to form the hook of the buckle tongue. The
dien retires, the peg p rises, and the gripping dies i, k, open and release the buckle
tongue which falls from the machine by the passage q (see Figure 4).
Figure 5 represents the partly made buckle tongue after the first pair of shaping
dies l, m, have operated upon it; and Figure 5B represents the finished buckle
tongue after the die n and peg p have operated upon it.
The several tools and moving parts of the machine are worked in the following
manner is the driving shaft, and s is the cam shaft driven by the toothed
gearing t. The lever & which operates the gripping feeding lever c and feeding
slide bis worked by the cam d² on the cam shaft 8. The moveable, cutting,
gripping, and pointing tool i is worked by the cam acting on the slide 5, the
return motion being effected by the spring . The return motion of the other
gripping and pointing tool is effected by the spring (see Figure 2). The
shaping die of the first pair of shaping dies l, m, is worked by the cam acting
on the slide 15, and the other shaping die m is worked by the cam m* acting through
the slides m³, me, and m7, (see Figure 1). The return motion of the die / is effected
by the spring 1, and that of the die m by the spring ms. The return motions of
the slides me and m are effected by the springs mo, m", respectively. The vertical
peg p is carried on the short arm of the lever u (see Figure 4), the long arm of the
said lever being acted upon by the cam p². The return motion of the lever u is
effected by the spring ps. The shaping or bending die n is operated by the cam n²
acting upon the lever n³, and the latter upon the slide nt. The return motions of
the lever n³ and slide n are effected by the spring n³.
Instead of feeding the length of wire into the machine by the arrangement

page_text: represented in Figures 1, 2, and 3, the modification represented in plan in Figure 6ª,
vertical section in Figure 7A, and a part separately in Figure 84 may be employed.
In this arrangement two feeding rollers v, w, are used, the roller w being plain on
its periphery, and the other roller v being provided with a feeding projection x.
The roller is shown separately in Figure 8. The rollers v, w, are carried on the
parallel shafts y, y², and are geared together by the toothed wheels at z. The
shaft У of the upper feeding roller is driven by the bevil gearing at 1 from the
cam shaft 8 of the machine. When by the rotation of the upper feeding roller v
its projection comes opposite the periphery of the other roller w, the wire a is
firmly gripped between the said projection x and the lower roll w, and by the con-
tinued rotation of the two rollers v, w, the required length of wire is fed into the
machine. As soon as the projection x leaves the periphery of the other roller wit
releases the wire a and the said wire comes to rest. By increasing or diminishing
the length of the gripping part of the feeding roller a greater or less amount
of feed may be imparted to the wire a at each rotation of the feeding rollers v, w.
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, as the same may be varied
without departing from the nature of my Invention; but I claim as my Invention,
the new or improved machinery for the manufacture of buckle tongues herein-
before described and illustrated in the accompanying Drawings, that is to say, the
combination of the tools i and k for cutting off, pointing, and gripping the length of
wire with the first pair of shaping dies l, m, and final shaping or bending die n and
peg p, the said tools and dies being constructed and operating substantially as
described and illustrated; also the combination of the said tools and dies i, k, l,
m, n, and peg p with the feeding mechanism represented in Figures 1, 2, and 3, or
with the feeding mechanism represented in Figures 6A, 74, and 84, for feeding the
length of wire into the machine, and also the combination or arrangement of parts
for actuating the said tools, dies, and peg, and feeding mechanism.
In witness whereof, I, the said Peter Macquay, have hereunto set my hand
and seal, this Twenty-first day of April, in the year of our Lord One thou-
sand eight hundred and seventy-seven.
