Year: 1886

page_text: I, THOMAS MITCHELL, residing at 248 Lafayette Avenue, Brooklyn, in the
County of Kings, and State of New York, in the United States of America,
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 an improvement in buckles and consists in a wedging
fastening so constructed that the strap may be held at any desired point, and it
further consists in certain peculiarities of the construction and combination of parts
as will be hereinafter fully set forth.
In the annexed drawings illustrating my invention.―
Figure, 1, is a side elevation of a shoe and roller skate secured together by means
of a strap provided with my improved buckle.
Figure, 2, is a representation of the blank which is to be bent into shape to form
the chamber of the buckle.
Figure, 3, is a cross section of the buckle when clamped upon a smooth metallic
strap.
Figure, 4, is a similar cross section when the fastening is clamped upon a flexible
strap.
Figure, 5, is a similar view of the buckle clamped upon a corrugated strap.
Figure, 6, is a plan view of a metal strap.
Figure, 7, is an edge view of a corrugated strap; and,
Figure, 8, is a perspective view of the buckle wedge.
Like letters of reference indicate like parts in the several figures.
A, represents the shank of the blank which is to be bent together at the line, x-x,
to form the buckle chamber frame, said shank being of any length that is desired,
and heing so formed that it may be riveted or otherwise secured to a strap, or may
be fastened direct to some object. The blank is preferably provided with lugs, B, B,
which will be bent to enclose the shank, & thus hold the top & bottom plates of
the chamber together.
The metallic blank is further provided with a transverse slot, C, which will be
on the under side of the chamber for the admission of the flexible strap to the
chamber as shown in figure, 4, another slot, D, is provided which will be at the end
of the chamber, the blank being bent at that point & through which the smooth

page_text: or corrugated metallic strap shown in figures, 6, &, 7, may pass. G, represents the
wedge which is preferably pivoted upon the lug, F, & is provided with a stop, a,
and a bent handle, B.
The movement of the wedge as shown by the arrow in figure, 1, is to and from
the buckle chamber, it being prevented by the stop, a, from entering too far within
the chamber, and yet its extent of movement being amply sufficient to allow it to
pass between the upper and lower plates of the chamber frame pressing against
the contained strap, and thus holding the latter firmly, and rigidly. Instead of
a smooth metallic strap, a corrugated strap, H, may be used in order to make
a more secure fastening and prevent liability of the slipping of the buckle. In this
case the side of the buckle chamber will generally be provided with corresponding
corrugations or grooves as shown in figure, 5. Also a leather strap will as shown
in the drawing be held securely by the wedge when it is properly placed within
the chamber and the wedge is clamped upon it.
It will be understood that I do not herein limit myself to the exact arrangement
of the parts just described, but reserve to myself the liberty of departing and
varying therefrom as shall be deemed best suited to the easy construction and
effective operation of the buckle, without however departing from the essential
features of my invention which are the chambered buckle, the clamping wedge, and
the smooth or corrugated straps.
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
1st. The combination of the chambered frame of the buckle, the strap passing
through slots in said frame, and the wedge, G, pivoted within the frame and having
a handle, b, substantially as described.
2nd. The combination of the buckle chamber having a corrugated side, the
correspondingly corrugated metallic strap, and wedging fastener, constructed and
operated substantially as shown and described.
3rd. The chambered frame of the buckle in combination with the wedge, when
.constructed and operated substantially as and for the purpose shown and described.
Dated this 18th day of May 1886.
