page_text: I WILLIAM PORTER WARD, of 46 Holborn Viaduct in the City of London,
Merchant, do hereby declare the nature of this Invention (a communication to
me from abroad by William Davis Stratton, of Boston, United States of America,
Manufacturer) 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 more especially to buckles made out of a single piece of
sheet metal or other springy material and it consists in such a buckle provided
with two tongues arranged with suitable cross bars and slots as described below, so
that it may be conveniently used as a means for adjustably attaching two straps. .
It also consists in a buckle, in which the edges of the tongue and cross bar
against which the strap is pressed by the tongue, have interlocking surfaces so that
the projecting portions of the tongue may force the strap into the retreating portions
of the cross bar, and vice-versa; the strap consequently being strained over the
several projections of the tongue and being held upon each of them and prevented
from slipping over to one side of the tongue, as often happens when the tongue of
the buckle is straight edged.
In the drawings is shown double buckles embodying this invention.
Fig. 1 is a plan of a buckle embodying the invention and Fig. 2. is a section
showing the manner in which such a buckle may be used. Fig. 3. shows such a
buckle provided with an extra loop or slot for the running strap, and Fig. 4 a
section showing its mode of use. Fig. 5 shows a buckle in which the two middle
cross bars are in one piece so that the buckle is without a middle loop. Fig. 6.
shows one form of interlocking surface and Fig. 7. is a cross section on line X X
of Fig. 6.
a. a¹ are cross bars, and 6 6¹ are tongues forming a part thereof. a care cross
bars adjacent to the free end of the tongues, and each serving with its tongue to
hold a running strap. Between the bars, a. a¹. (except in the buckle shown in
Fig. 5. which has only a single crossbar a) is the slot d capable of holding the ends
of one or both straps (see Figs. 2 & 4). e is a crossbar at the end of the buckle
which with the crossbar c¹ forms the slot f. The main purpose of this slot will be
understood by reference to Fig. 4. of the drawings.
A. & B. are two straps, one of which A., is used as the standing strap, that is ;
the strap permanently attached to the structure, by means of the tongue 6¹, its end

page_text: being tucked into slot d. The strap B. being passed under the tongue b, is passed
over the buckle and down through the slot f.
The projections g. glare for the purpose of raising the tongue, to release the strap.
The holding edge of the tongue, and cross bar next it, may be provided with a
crooked interlocking edge, so as to offer several projections over which the strap
shall be strained, and so be both held in the buckle, and prevented from sliding
sideways into the space at the side of the tongue.
One form of edge useful for the purpose is shown in Figs. 1 and 3. of the
drawings, and another in Fig. 6.
These edges are cut with a die having a crooked blade which separates the
tongue from its adjacent cross bar, while the remainder of the die cuts and finishes
the buckle.
The edge of this buckle may be embossed or strengthened in any one of a number
of known ways, if thought best. One way of strengthening such a buckle, is by
providing it with a truss at each side. A buckle so strengthened is shown in
Figs. 6. and 7. in which h. h. are the trusses.
They are widest at the weakest part of the buckle, viz; at the loop d, and
become narrower as they approach either end of the buckle. These trusses standing
at right angles to the face of the buckle, take the strain which otherwise would
tend to bend it, and by reason of their shape and position strengthen the buckle
⚫ materially.
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 buckle above described cut from one sheet of material, and consisting of
the cross bars a. a¹ between which is the slot d, the tongues 6 6 forming a part of
said cross bars, and the cross bars c. c¹ adjacent to the free ends of the tongues,
each cross bar c. c¹ adapted with its tongue to hold a running strap, all as set
forth.

2d The buckle above described cut from one sheet of material and consisting of
the cross bars a. a¹ between which, is the slot d, the tongue b. 6' forming a part
of said cross bars a. a¹, the cross bars c. c¹ adjacent to the free ends of said tongues
each cross bar c. c¹ adapted with its tongue to hold a running strap, and the end
cross bar e. forming, with the cross bar c¹, the slot f, all as set forth.
3d The buckle above described, cut from one sheet of material, and consisting
of tongues b. b¹ each projecting from a cross bar and forming a part thereof, and
the cross bars c. c¹ adjacent to the free ends of said tongues, all as set forth.
4th The buckle above described cut from one piece of sheet material provided
with suitable means for attachment to a standing strap having a spring tongue
projecting from a cross bar, a. and forming a part thereof and a cross bar, c,
adjacent to the free end of said tongue and adapted, with said tongue, to hold a
running strap, the holding edge of said tongue being crooked and interlocking with
the corresponding crooked holding edge of its adjacent cross bar, all substantially
as set forth.
5th The buckle above described cut from one piece of sheet material, having one
or more tongues and suitable cross bars and provided with strengthening trusses h. h.
arranged as described and adapted for the purposes set forth.
