PROVISIONAL SPECIFICATION.
Improvements in Buckles.
I, AUGUST TRECKMANN of Crefeld, in the Empire of Germany, Manufacturer do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in that class of buckle described in the
specification of Letters Patent No. 1299 of 1885.
According to the present invention the sliding serrated or holding bar is provided
with a spring or formed to act spring-wise in such a manner that when there is no
tension or strain on the strap, the said bar automatically presses against the loose
part of the strap and thereby prevents the same from slipping.
To adjust the strap it is simply necessary to draw back the bar.

COMPLETE SPECIFICATION.
Improvements in Buckles.
I, AUGUST TRECKMANN, of Crefeld, in the Empire of Germany, 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 improvements in that class of buckle described in the
specification of Letters Patent No. 1299 of 1885.
According to the present invention 1 provide a spring or springs arranged to
act on the sliding serrated or holding bar, or I form the said bar to act spring-wise,
in such a manner that, when there is no tension or strain on the strap, the said bar
automatically presses against the loose part of the strap and thereby prevents the
same from slipping.
To enable my invention to be fully understood I will describe how it can be carried
into practice by reference to the accompanying drawing, in which :
Figure 1 is an elevation; and
Figure 2 is a cross section of a buckle provided with my improvement.
Figure 3 is an edge view illustrating the application of my improved buckle to a
strap or straps.
Similar letters in all the figures indicate similar parts.
A and B are the two parts of the buckle.
a is the bar of the part A to which one end b of the strap is attached; c, c are
the side portions connecting the bar a with the adjustment bar d.
g is the serrated or holding bar of the part B, and g³, g' are the side portions
connecting the bar g with the adjustment bar h; e, e are the turned-over portions
of the bar g which clip the sides c of the part A, all the said parts being substan-
tially of the same construction as those of the buckle described in the specification of
the said former Patent.
, are the springs with which I provide the buckle, the said springs being shown,
by way of example, secured to the side bars c, c and bearing against the clips e, e
of the serrated or holding bar g.
By this arrangement, when there is no tension or strain on the strap f, the latter,
instead of being liable to slip out of the buckle as hitherto, will be held by the
serrated bar which is automatically caused by the springs x to constantly press the

page_text: loose part of the strap between itsell' and 'the bar (as shewn in figure 3) and thereby
prevent the strap from slipping.
To adjust the strap it is simply necessary to draw back the serrated bar 9
the strap will be free to be drawn through the buckle.
when
Instead of providing the buckle with springs of the form shown it is obvious that
any other suitable form of spring may be employed.
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 :-
1. The combination with a buckle of the kind herein before referred to, of a spring
or springs, substantially as, and for the purpose, set forth.
2. The improved buckle herein before described and illustrated in the accompanying
drawing.
