PROVISIONAL SPECIFICATION.
Improvements in, and in the Manufacture or Production of, Brace
and other Buckles.
I, THOMAS WALKER of Brook Street Works, St. Paul's Square, in the City of
Birmingham Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention relates to, and to the production of, the frames of buckles, as herein-
after described, whereby the said buckle frames, are made neater in appearance, and
the cost of their manufacture greatly reduced.
The first part of my invention consists in the buckle frame, secondly in the production
of the said frame from wire, or other drawn metallic lengths.
In carrying out the first part of my invention, I form a long rectangular three
sided frame, with a flattened top bar, and round side bars, with the junctions of the
latter with the former, rounded at both the corners, and at the fronts and backs.
Directed inwardly from the opposite side bars, and parallel to the top bar, are two
pivots or joint centres, upon which, the tubular, and open ends of the prong-bar,
passes.
Thus, the prong bar, which carries the prongs, consists of a length of tubing, equal
to the inside breadth of the frame, and turning upon the turned in ends of the side
bars as joint centres.
In carrying out the second part of my invention, I take a piece of round wire of
the diameter of the side of the frame to be produced, and of a single length, sufficient
to form both the top and side bars, and also the joint centres, for the prong bar to
turn upon.
This said length of wire, is then bent into a three sided frame, with the ends of the
side bars, directed inwardly. I then by dies and pressure flatten out and shape the
top bar, and its junctions with the side bars; and I also square, and give shape to
the turned-in ends of the said side bars, which are to form reduced joint centres, for
the ends of the tubular prong bar to turn upon.
This said frame is thus produced from wire, and in one piece.
I do not confine myself to the section of wire employed or to the shape of the
frame, nor as to whether the top and joint parts, be shaped before, or after the fashioning
of the frame.
In making the frames from drawn wire instead of from cut out sheet metal, a great
saving in the cost of production is effected.

COMPLETE SPECIFICATION.
Improvements in, and in the Manufacture or Production of, Brace
and other Buckles.
I, THOMAS WALKER of Brook Street Works, St. Paul's Square, in the City of
Birmingham, Manufacturer, 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 :-
This invention relates to brace, and other buckles, and particularly to the frames
thereof, and their production or manufacture.
By my invention, the said buckle frames, are neater in appearance, and the cost of
their manufacture, greatly reduced.

page_text: Thus, my invention consists in the first part of a buckle frame, and secondly in the
production of the said frame from wire, or other drawn or rolled metal lengths.
According to the first part, I produce a long rectangular shaped three sided frame,
with a flattened top bar, and round side bars, and with the junctions of the latter
with the former, rounded off at both corners, and also at the fronts and backs
thereof.
Directed inwardly from the opposite side bars, and parallel to the top bar, are two
pivots or joint centres, upon which, the tubular and open ends of the prong-bar, pass
and take.
Thus, the prong bar, which carries the prongs, consists of a length of tubing, equal
to the inside breadth of the frame, and turning upon the turned-in ends of the side
bars, as joint centres.
In the second part of my invention, 1 take a piece of preferably round wire, of a
size equal to the sides of the frame to be produced, and of a single length, sufficient
to form both the top and side bars, and also the joint centres, for the prong bar to
turn upon.
The said length of wire, is then bent into a three sided frame, with the ends of the
side bars, directed inwardly. I then by dies and pressure, flatten out and shape the
top bar, and its junctions with the side bars; and I also square, and give shape to
the turned-in ends of the said side bars, which are to form reduced joint centres, for
the ends of the tubular prong-bar, to turn upon.
I do not confine myself to the section of wire employed, or to the shape of the frame,
nor as to whether the top and joint parts, be shaped before or after the fashioning of
the frame.
By making the said frames from drawn wire, or metal strips, instead of cutting out
the frame or frame blank from sheet metal, a great saving in the cost of production,
is thereby effected.
Figure 1 of the accompanying drawings, represents in front elevation, a buckle,
provided with a buckle frame, made according to my invention.
Figure 2 is a transverse section of the same.
Figure 3 is an elevation of the said buckle frame, and Figure 4 a transverse
section of it.
a are the opposite sides of the frame, terminating in a flat top bar b, in one
direction, and by reduced pivot centres in the other direction, and upon which
centres, the tube prong barrel d, takes and turns, and carries the prongs d².
The junctions of the top bar b, with the sides a, are rounded off, and so also are
the junctions of the sides a, with the reduced pivot or trunnion-like centres c.
The frame is preferably produced from wire, or from a length of strip metal as
hereinafter described, and which constitutes the second part of my invention.
Figure 5 represents a front elevation of a buckle, whose frame is made from
round wire.
Figure 6 is a transverse section of the same.
Figure 7 is a like view as Figure 5, but with the ends of the prong barrel
broken away, in order to show how they take upon the reduced centres, or trunnion
portions of the frame.
In producing the said frame from wire, I take a length alike unto Figure 8,
and bend the same into the shape Figure 9, and then by dies and pressure,
fashion the same into the form Figure 10, consisting of a frame, with round side
bars a, flattened top bar b, with the junctions of them, rounded off at 62, and reduced
or trunnion centres c. The said centres are reduced from the metal of the turned-
in parts of the blank Figure 9, by squeezing a portion of the metal, out into a web,
which is subsequently clipped by suitable tools.
The production of the said frames from strip metal differs in no essential respect
from the production of it from drawn metal.
Instead of employing reduced joint centres c, I may provide the insides of the
lower ends of the sides a, with recesses or bearings, wherein the ends of the prong
bar d, takes and rotate.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First: A buckle frame, consisting of sides a, a, flattened bar b, and inwardly
directed, reduced joint centres or trunnion centres c, for taking the ends of the tubular
prong bar, substantially as described and set forth in Figures 1, 2, 3, and 4.
Secondly-Making a three-sided, or other like rectangular shaped buckle frame,
from wire (or strip metal), or a single length of wire, which is bent into shape, and
operated upon, substantially as described and set forth in Figures 8, 9, 10, and 11.
Thirdly-Making a three-sided, or other like rectangular shaped buckle frame,
with joint centres, or reduced joint centres, from wire (or strip metal) or a single
length of wire, which is bent into shape, and fashioned, substantially as described and
set forth.
