I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this Invention (a communication to me
from abroad by Charles Menger Merchant residing at 470 North 2nd Street
Brooklyn in the county of Kings and State of New York United States of
America) 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 adapted especially for use in fastening shoes or
overshoes, but applicable also as a glove fastener, or a general strap fastener, and
the object of the Invention is to provide a simple inexpensive and effective buckle
of this character.
The Invention consists in certain novel features of construction and combinations
of parts of the buckle; all as hereinafter fully described and claimed.
Reference is to be had to the accompanying drawings forming a part of this
specification in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1. shows the improved buckle with the tongue separated from the clamp
or head, as when the parts to which the buckle is attached are unfastened; figure 2.
shows the tongue wedged in the clamp or head, as when the parts to which the
buckle is attached are fastened or buckled together. Figure 3. is a longitudinal
central sectional elevation of the buckle; figure 4. is an end view of the buckle
clamp, and figure 5 is a plan view of the blank of which the main portion of the
buckle clamp is made.
يا
The main portion or clamp of the buckle comprises a bent plate A of any
suitable metal, and a metal wedge or plate B pivoted to the plate A by a pin b.
This clamp plate A is formed from a blank.D shown in figure 5 and which has a
long lip portion d at one end pierced at d' for the passage of a rivet b¹ by which
the clamp A. B. is to be held to a tab E shown in dotted lines and which is to be
fixed to the body of a rubber or "Arctic" overshoe for instance, or to the end of
a strap, or the clamp may be held by the rivet directly to the wrist of a glove at
one side of the longitudinal slit or opening of the glove. At the inner end of the
part & of the blank, the latter is widened at both sides forming opposite side
lips d d and the blank is provided transversely and about in line with the

page_text: centres of the opposite lips d d with a slot d³. Beyond the lips d² d³ the blank
has a couple of notches d d at each side whereby opposite lips d³ d³ are produced
and beyond the notches d* d* the blank has opposite lateral end lips do d', the
lip de having a hole d³ through which the wedge plate pivot b is passed.
To shape the blank C to produce the buckle clamp plate A the blank is bent or
doubled over on the line 11 figure 5 or at the centre of the slot d³ thereby forming
an upper or outer part a to the inner face of which the wedge plate B is pivoted
at b, and a lower or inner and longer part a¹ which is curved or bent back ward to
provide a wedge shaped space between the parts a a¹ into which the pivoted
wedge B may be turned to clamp firmly to the part a¹ of plate A the tongue C of
the buckle the end of which is passed into the slot d at the bend of the blank, and
as clearly shown in figures 2 and 3 of the drawings. The opposite lips d³ ³ of
the blank are turned over beneath the part a¹ to stiffen it and support it against
the thrust or pressure of the wedge B on the tongue C see figures 3 and 4.
The buckle-tongue C is a piece of plate-metal curved flatwise in direction of its
length and having a hole c at its back end through which a rivet c¹ is passed to
hold it to the end of a tab or strap F indicated in dotted lines in figures 1 and 2.
The other end of this tab F is to be attached to the body of an overshoe; or the
tongue C may be fastened at one side of the slit of a glove to which, at the other
side of the slit, the clamp A, B may be attached as above intimated. The side
lips d d of the blank D allow the slot d to be made long enough to accomodate
a tongue C quite as wide as the part 'd of 'the blank and yet leave the plate A
amply strong to resist all strains to which it may be subjected. The lip d of the
Blank D serves as a guard to protect the projecting end portion 63 of the wedge B
from contact with objects which would tend to swing the wedge back and open the
buckle and this part 6 of the wedge is preferably provided with a lip b³ for greater
convenience in operating the wedge to fasten or unfasten the buckle.
Having now particularly described and ascertained the nature of the said
Invention; and in what manner the same is to be performed I declare that what
I claim is
.T
1. A buckle comprising a clamp formed of a metal plate A bent double and
having a slot as at d³ at the bend, a wedge plate B pivoted to plate A and adapted
to be turied in between the inner and outer parts of the plate A and a tongue C
adapted to be passed through the slot d³ of plate A and to be clamped therein by
the wedge plate B substantially as herein shown and described.
2. In a buckle, the clamp comprising a main plate A formed of a blank D having
lips d, d³ d³, d³ d³, and transverse slot d and bent over transversely at the slot ³
to form outer and inner parts a a¹, and said lips do bent beneath the part a¹ of
the doubled plate; and the wedge plate B pivoted at b to the part a and adapted
to be turned between the parts a a¹ to clamp the buckle tongue in and to the
plate A substantially as described for the purposes set forth.
:
3. In a buckle, the clamp plate A forined of a blank D having a longitudinal
lip d and transverse lips d² d³, d³ d³, dº, d', and a transverse slot d³ and bent over
transversely at the slot d³ to form outer and inner parts a a¹ and said lips d³ bent
beneath the part a¹ and a wedge plate B pivoted to lip do and adapted to be:
turned inward to clamp the buckle tongue in and to the plate A, substantially as
described, for the purposes set forth.
