An Improved Strap Buckle.
I, PHILIP ARTHUR NEWTON of The Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, 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:-
The appliance that forms the subject of the present application for Letters
Patent is a simple buckle device, whereby, when the free end of the strap is
introduced into the buckle, the latter shall be caused to grip it automatically,
so that the greater the strain that is put upon the strap, the firmer will the
buckle be caused to hold it.
But in order that the invention may be more thoroughly understood, reference
will be made to the accompanying sheet of drawings, in which
Fig. 1 is a longitudinal section of the buckle taken on the line 1-2 of Fig. 2.
Fig. 2 is a plan of the same.
A A are the side plates of the buckle. B is the end bar, to which the strap B¹
is fastened. The free ends of the side plates A are turned up, and the two ends
connected together by a cross piece C, which is provided with a rolling sleeve C¹.
Between the two end cross pieces B and C is a third cross piece D, that forms the
axis of a cam E, the outer edge of which is roughened or serrated, as at e. The
sides of the cam E are provided with salient stops or studs F F, which will
prevent the cam E from being rotated beyond a certain position, as shewn in
Fig. 1, and may be inade so as to project slightly beyond the side plates, so as
to afford a finger-hold, to release the strap, as shewn in Fig. 2. The cam E is
provided with a light spring G, by means of which the cam E shall be lightly
retained in such a position that the stops F shall lie upon the upper edges of
the side plate A.
When it is desired to secure the free end of the strap in the buckle, the end
of the strap is pushed through the space between the sleeve C' and the cam E,
which latter will give way slightly, to allow the strap to pass, when forced in
from that direction, but as soon as any tension is brought to bear on the strap,
the serrated edges of the cam will grip the under surface of the strap, and hold
the same firmly between such serrated edges of the cam and the sleeve C¹.
The cam might be used without the spring G, but experience has taught that
with the spring much less manipulation of the buckle is required, as the cam is
always close up against its work.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed (as communicated to me
from abroad), I declare that what I claim is:-
A strap buckle consisting of two side plates, an end cross bar to which the strap
is attached, a fixed cross bar such as C, at the ends of the side plates most remote

page_text: from the secured end of the strap, and a medially placed cam baving serrated
edges that will grip the free end of the strap between itself and the cross piece, as
and for the purposes herein set forth.
Dated this 2nd day of September 1896.
