Improvements in Buckles for Securing Straps.
1, THORWALD BRANDT, of 13, Eichstrasse, Baden-Baden, in the German Empire,
Joiner, 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 buckles for fastening straps of leather or other material,
especially leather harness-straps of large size.
The buckles hitherto used, particularly when employed with heavy leather straps,
are difficult to fasten and equally difficult to unfasten. The object of the present
invention is to provide a buckle suitable for use with heavy leather straps and capable
of being easily manipulated.
In the accompanying drawings,
Fig. 1 is a longitudinal section shewing a buckle constructed according to this
invention and serving to connect two straps or the ends of a belt. The position of the
parts when the buckle is open is indicated by dotted lines.
Fig. 2 is a plan of the buckle when open; the straps being omitted.
Fig. 3 is an end elevation of the opened buckle; the straps or the ends of the belt
being represented in transverse section.
Fig. 4 is a perspective view of the fastening plate.
To the strap A is secured a plate B, from which project at right angles two side-pieces D
and D¹. The fastening plate G is pivoted on the pin E. and carries a stud H, which
passes through any one of the holes i in the strap K and into the hole C in the plate B.
A locking plate L having a projection or toe M and a catch is pivoted on the pin F,
and serves to raise and lower, and lock in the lowered position, the plate G, which is
formed with an upwardly-projecting tongue R.
The action of the parts is as follows:-In raising the plate L from the position
shewn in Fig. 1 to the position indicated by dotted lines in that figure, the toe M engages
with the tongue R and raises the fastening plate G, thus withdrawing the stud H, so that
the end of the strap K. can be readily pulled out of the buckle. In depressing the plate L
into its normal position, the toe M slides over the surface of the plate G (which may be
hollowed, as shown at N) and causes the plate G to return to the position shewn in
Fig. 1, the stud H passing through one of the holes and into the hole (. Finally,
the catch O snaps over the knuckle P of the plate G, and the parts are securely locked
in the closed position.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 claim :-
The improved buckle for securing straps or belts, constructed substantially as herein
described, and having a fastening plate G, provided with a stud H and a tongue R, as
also a pivoted locking plate L formed with a toe M; the plate G being raised or
depressed by the plate L accordingly as the toe of the latter engages beneath the
tongue R or against the back of the plate G.
Dated this 3rd day of October 1890.
