IMPROVEMENTS IN THE MANUFACTURE OF BUCKLES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We, THOMAS EVANS of Summit Works Walsall, in the County of Stafford,
Manufacturer, and WILLIAM DEAYMAN of 4 Sandwell Street, Walsall, in the
County of Stafford, Manager do hereby declare the nature of our invention for
"IMPROVEMENTS IN THE MANUFACTURE OF BUCKLES" to be as follows:-
Our Invention relates to Improvements in the manufacture of Buckles such as
are used for fastening braces, belts, straps, bands and other articles, and for other
purposes to which buckles are ordinarily applied; and it relates particularly to
that class of buckles which consist essentially of two parts, that is to say; firstly, a
metal tongue-piece having formed therewith or attached thereto a spike or spikes;
and secondly, a metal frame partly forming a cross-bar against which the spike or
spikes rests or rest when the buckle is closed. The tongue-piece and the frame are
binged or jointed together at each side so that they are capable of being turned on
their hinge or joint to lift the spike or spikes away from the cross-bar of the frame
or to turn it or them against the cross-bar of the frame..
The object of our Invention is to improve the method of hinging or jointing
together the tongue-piece and the frame. An ordinary method of hinging or
jointing together the tongue-piece and the frame is by bending parts of the tongue-
piece round parts of the frame, the said parts of the frame forming joint pins round
which the tongue-piece may revolve.
The said parts of the tongue-piece often break in bending, thereby causing loss,
but according to our Invention we joint or hinge the tongue-piece and the frame
together as follows; that is to say, we shape the frame at the sides to form two
joint pins turned towards each other in, or approximately in, the same straight
line; and we provide in the sides of the tongue-piece two holes for the said pins to
enter. Parts of the tongue-piece forming the holes for the pins are wanting for
nearly half the diameters on either side, but not at the same part of the pins, so
that by slightly springing the frame open the pins can be inserted in the holes and
the joint or hinge thereby formed.
We make our improved buckles either of cast metal or stamp them by means of
suitable dies from sheet metal.

Manufacturer, and WILLIAM DEAYMAN, of 4, Sandwell Street, Walsall, in the
County of Stafford, Manager, do hereby declare the nature of our invention for
"IMPROVEMENTS IN THE MANUFACTURE OF BUCKLES" and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :—
Our Invention relates to Improvements in the manufacture of buckles such as
are used for fastening braces, belts, straps, bands and other articles, and for other
purposes to which buckles are ordinarily applied; and it relates particularly to
that class of buckles which consist essentially of two parts, that is to say; firstly, a
metal tongue-piece having formed therewith or attached thereto a spike or spikes;
and secondly, a metal frame partly forming a cross-bar against which the spike or
spikes rests or rest when the buckle is closed. The tongue-piece and the frame are
hinged or jointed together at each side so that they are capable of being turned on
their hinge or joint to lift the spike or.spikes away from the cross-bar of the frame
or to turn it or them against the cross-bar of the frame.
The object of our Invention is to improve the method of hinging or jointing
together the tongue-piece and the frame. An ordinary method of hinging or
jointing together the tongue-piece and the frame is by bending parts of the tongue-
piece round parts of the frame, the said parts of the frame forming joint pins round
which the tongue-piece may révolve.
The said parts of the tongue-piece often break in bending, thereby causing loss,
but according to our Invention we joint or hinge the tongue-piece and the frame
together as follows; that is to say, we shape the frame at the sides to form two
joint pins turned towards each other in, or approximately in, the same straight
line; and we provide in the sides of the tongue-piece two holes for the said pins to
enter, Parts of the tongue-piece forming the holes for the pins are wanting for
nearly half the diameters on either side, but not at the same part of the pins, so
that by slightly springing the frame open the pins can be inserted in the holes and
the joint or hinge thereby formed.
We will now proceed to describe with reference to the accompanying Drawing
the manner in which our Invention is to be performed; the same letters of
reference on the Drawing indicate corresponding parts in all the corresponding
.Figures.
Figure 1 is a front view; Figure 2 is a side view; Figure 3 is a sectional plan
on line X. X. of Figure 1; and Figure 4 is a back view of a brace buckle of cast or
stamped metal having the tongue-piece and. the frame hinged or jointed together
according to our Invention; Figures 5 and 6 represent separate views of the
tongue-piece and the frame respectively and which are shewn partly hinged or
jointed together in Figure 7; Figure 8 represents a sheet metal blank for forming
the tongue-piece; Figure 9 is a sectional elevation of the tools for forming the
hinged or jointed parts of the said tongue-piece blank; Figure 10 is a cross
sectional elevation of the same; Figure 11 is an inverted plan of the top tool and
Figure 12 is a plan of the bottom tool; Figures 13, 14, 15, 16 represent views of n
brace buckle of cast or stamped metal with a modified form of hinge according to
our Invention.
A is the metal frame partly forming a cross-bar for the spikes 63 to rest against
when the buckle is closed and being shaped at the sides to form two joint pins a³, a²

page_text: turned towards each other. B is the tongue-piece having formed therewith the
spikes 6 and having provided in the sides the two holes b', b* for the pins a¹, a³ to
enter. Parts of the tongue-piece forming the holes b¹, b³ for the pins a¹, a³ are
wanting for nearly half their diameters on either side but not at the same part of
the pins, as at 6, 68, so that there remain two bars 6º, 6' on opposite sides of each
pin. By springing or bending the frame open as shown in Figure 6 the pins can
be inserted in the holes as shewn in Figure 7 and can then be pressed together to
form a joint or hinge as shewn in Figures 1, 2, 3, 4 and 13, 14, 15, 16. The
bars be may be either at the front and the bars 6 at the back of the buckle
as shewn in Figures 1 to 7, both inclusive, or the bars 6 may be at the back and
the bars 67 at the front of the buckle as shown in the modified form in Figures
13 to 16, both inclusive. In this said modified form projections a³ have to be
provided on the frame to work against the bars 67 and prevent the said frame
moving endways.
We make our improved buckles either by casting in the ordinary manner or we
stamp them from sheet metal by means of suitable dies. The sheet metal blank
for the tongue-piece shewn in Figure 8 has been stamped out by ordinary press
tools and has two bars 66, b7 at each side. By means of the top tool N and the
bottom tool M, each having projections m¹, n¹ and recesses m³, n³ of suitable form,
as shewn in Figures 9, 10, 11 and 12, the said bars 66, 67 will, when the top tool
descends, be formed of semi-circular shape to take the pins a¹, a on the frame.
We wish it to be understood that we do not confine ourselves to the general
shape or form of the buckle as herein described and illustrated as it is evident our
improved method of hinging or jointing is applicable to any buckle which consists
essentially of a metal tongue-piece and a metal frame.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. A metal buckle having the tongue-piece formed at its hinged parts sub-
stantially of the shape and for the purpose herein before described and illustrated
in Figures 1 to 8, both inclusive, of our Drawing.
2. A metal buckle having the tongue-piece formed at its hinged parts sub-
stantially of the shape and for the purpose herein before described and illustrated
in Figures 13 to 16, both inclusive, of our Drawing.
