I V. A. COLEMAN of the Town of Port Hope in the County of Durham in the
Province of Ontario in the Dominion of Canada Manufacturer, do hereby declare the
nature of this invention to be as follows, reference being had to the accompanying
drawings:-
:-
Figure I represents the buckle as it is in use. The parts towards A are called the
front and those toward B are called the back.
C is a bottom plate having suitable loops for the attachment of straps as may be
required for different uses, and a groove, recess, or processes for keeping the bail
in position.
D is a top plate with an independent tongue plate E hinged thereto at the rear end.
F is a bail connecting the top and bottom plates.
The tongue plate E shuts down over the bail having an arched recess to fit some-
what loosely. The bail also rests between processes of the top plate so as to keep it in
position.
The tongue plate has a tongue G figure II projecting downward through an
opening H in the top plate and into a hole in the trace to prevent the trace drawing
through the buckle.. This tongue also when closed down, rests against the rear edge
of the said opening in the top plate to relieve the tongue plate and hinge pin from
strain.
The tongue plate also has a spring box K at its rear end which fits into a spring box
in the rear end of the top plate. A hinge-pin passes through this spring box so as to
form a hinge. The spring is enclosed in this spring box and has one of its bearings on
the tongue plate and the other on the top plate at the rear of the hinge pin thus
keeping the tongue plate in its locking position.
Any suitable spring may be used in this buckle but that commonly to be used is
made of good highly elastic spring wire that will not easily corrode and about number
nineteen wire guage. It is formed in alternate loops and coils in the following
manner-
The wire is carried forward about half an inch then coiled about an axis, in a circle
a little larger than the hinge pin, about one and a half times; then backward about

page_text: half an inch; then turned outward and forward forming a close loop and again about
the same axis as before about one and a half times and backward about half an inch
to the place of beginning-when it is again turned outward and forward forming a
close loop and thus continued till as many coil and loop are formed as convenient or
desired when the springs may be cut apart.
Each spring has about six loops, more or less as desired for different sizes of buckles,
about three of these loops will bear upon the tongue plate and three
upon the top plate.
The hinge pin passes through the coils of the spring. The loops which bear upon the
tongue plate should be a little shorter than those which bear upon the top plate.
In use the trace is conveniently and easily taken up or shortened by shoving it
forward. The pressure upon the tongue causes it to rise and the trace may be thrust
forward as far as desired and the tongue let fall into the desired hole. In letting
out or lengthening the trace the tongue is raised by shoving the trace and it is then
held up and the trace drawn back and the tongue let fall into the proper, hole.
This buckle is simple, effective, and durable, and its construction is also simple.
What I claim as my invention is
1. The combination of the said tongue plate, top plate bail and bottom plate so as to
form a buckle substantially as described.
2. The bearing of the said tongue upon the rear part of the said opening of the top
plate to relieve the tongue plate and binge pin of strain substantially as described.
3. The construction and use of the spring and spring box substantially as described.

page_text: the buckle. This tongue G also, when closed down, rests against the rear edge of the
said opening H in the top-plate D (as shown in figures 1, 2 and 5), to relieve the
tongue-plate and hinge-pin k from strain. The tongue-plate E may be provided on its
outer or free end with a thumb-piece E¹, a ring, or other similar contrivance for
facilitating the release of the trace.
The tongue-plate also has a spring-box K at its rear end, which fits into a spring
box K¹ formed on the rear end of the top-plate D. A hinge-pink passes through
this spring-box so as to form a hinge connecting the tongue-plate E to the top-plate D.
A spring M is enclosed in this spring-box and has one of its bearings on the tongue-
plate E and the other on the top-plate D at the rear of the hinge-pin k, thus keeping
the tongue-plate E in its locking position as shown in figures 1, 2 and 5.
Any suitable spring may be used in this buckle but that commonly to be used is
made of good, highly-elastic spring wire that will not easily corrode, and about
number nineteen wire gauge. Figure 6 is a separate view of the said spring on an
enlarged scale. It is formed in alternate loops m m¹ and coils m³ in the following
manner. The wire is carried forward about half an inch, then coiled about an axis
in a circle a little larger than the hinge-pin k about one and a half times, then back-
ward about half an inch, then turned outward and forward forming a close loop, and
again about the same axis as before about one and a half times, and backward about
half an inch to the place of beginning when it is again turned outward and forward
forming a close loop and thus continued till as. many coils m² and loops m, m², are
formed as convenient or desired when, the springs may be cut apart.
Each spring M has about six loops, more or less, as described for different sizes of
buckles, about three of these loops will bear upon the tongue-plate E and three upon
the top-plate D. The hinge-pin
passes through the coils m³ of the spring. The
loops in which bear upon the tongue-plate E should be a little shorter than those m
which bear upon the top-plate D.
In use the trace L is conveniently and easily taken up or shortened by shoving it
forward. The pressure thus exerted upon the tongue G causes it to rise and the trace
may be thrust forward as far as desired and the tongue G let fall into the desired hole
in the trace.
In letting out or lengthening the trace, the tongue G is raised, either by shoving
the trace or by means of the thumb-piece E¹, and it is then held up, the trace drawn
back and the tongue G let fall into the desired hole in the trace.
This buckle is simple, effective and durable, and its construction is also simple.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :—
First The combination of the said tongue-plate E, top-plate D, bail F and
bottom-plate C, so as to form a buckle, substantially as described.
Second-The bearing of the said tongue G upon the rear part of the said
opening H of the top-plate D, to relieve the tongue-plate E and hinge-pin k of
strain, substantially as described.
Third The construction and use of the spring M and spring box K, K¹
substantially as described.
