SLIDE BUCKLE
Daniel I. Reiter, New York, N. Y.
Application May 3, 1938, Serial No. 205,673
5 Claims.
This invention relates to slide buckles and par
ticularly to the type designed to have one belt or
strap end secured thereto and a cooperating belt
I6, I1 on the end bars I8 and I9 respectively serve
to limit such movement.
Extending from the bend I4 and formed inte
or strap end passed therethrough and locked into
grally therewith is the bendable securing plate 20.
Said plate is preferably narrower than the body
5 position to secure the belt in an adjusted position
to the buckle.
In slide buckles heretofore known, in which a
cross bar is slidable on a frame, the end of a strap
is secured to the slidable cross bar customarily by
10 looping the strap end about the cross bar and
then stitching the thus looped or folded-over end
of the strap or belt to close the loop.
This operation is inconvenient and compara
tively expensive and my invention, therefore, con
15 templates the provision of bendable metallic
means whereby the strap end is secured to the
cross bar adequately and ñrmly by a bending op
eration without the necessity for any sewing oper
ation.
20
My invention further contemplates the provi
‘
sion of means on the slidable cross bar of a slide
buckle for securing a strap end in place to the
cross bar, said means comprising a pair of mem
bers bendable on to the remainder of the cross
25 bar and means on said members cooperating with
the remainder of the cross bar to mechanically
stitch the belt end in place when said members
are bent.
-
The various objects of the invention will be
clear
from the description which follows and from
O

the drawing, in which,
Fig. 1 is a front elevational view of a buckle em
bodying my invention and showing the ends of a
strap held thereby.

(Cl. .Z4-196)
Fig. 2 is a horizontal section of the same taken
on the line 2-2 of Fig. 1.
Fig. 3 is a rear elevational View of the same.
Fig. 4 is a perspective view of the buckle as it
appears when furnished to the consumer, the
40 belt-securing means outstanding initially at an
acute angle to the remainder of the cross bar of
the buckle, preparatory to receiving the belt end
therebetween.
In the practical embodiment of the invention
45 which I have shown by way of example, the buckle
frame I0 is preferably made of a single piece of
sheet metal being provided with the pair of lon
portion 2l of the cross bar and at its edges is pro
vided with suitable prongs as 22, bent at substan
tially right angles to the plate 20 and directed
toward the body portion 2|. While the prongs 22
are illustrated as extending from the edges of the 10
plate 20, it will be understood that said prongs
may extend from any desired point of the plate as
will be obvious and hence needs no illustration.
Initially the plate 20 extends from the bend Ill at
an acute angle to the body portion 2|, leaving i
sufûcient room between said plate and said body
portion for the insertion of the strap end 23
therebetween.
In said body portion, perforations or recesses 24
are formed at the proper points to register with n
and receive the prongs 22 when the plate 20 is
bent towards the body portion. It will be under
stood, however, that in place of complete perfo
rations the material of the body portion may be
indented or depressed to provide depressions or
recesses corresponding to the perforations 24 and
functioning similarly thereto but closed by the de
pressed portion or wall of the material thereof.
A plate 25 similar in all respects to the plate 20
extends from the bend I5 of the cross bar at a 30
corresponding acute angle, said plates 20 and 25
being arranged adjacent the inner face of the body
portion and being directed toward each other but
being each spaced sumciently from the body por
tion 2l to permit the belt end 23 to be inserted
thereunder.
The end 23 of the belt or strap to be secured to
the cross bar, after having been inserted between
the plates 20, 25 and the body portion 2 I, need not
be looped about the cross bar, but is readily se
cured in place by merely bending said plates to
ward the body portion 2|, and into substantially
parallel relation thereto. When this -is done, said
plates firmly hold the belt end in place while at
the Sametime the prongs 22 either puncture the
belt end or force the material of said belt end into
the perforations or recesses 24.
Whether or not
gitudinally extending spaced parallel side bars I I
the belt end is punctured by the prongs 22, said
and I2. Extending between and secured to said
prongs enter the recesses or perforations 24 and
50 side bars is the sliding cross bar I3 also made of a
thereby mechanically stitch the belt end to the
single piece of metal. At its ends the cross bar I3
is provided with suitable 180° bends I4 and I5
each extending around one of the side bars I I and
I2, so that the cross bar may slide from one end of
55 the side bar to the other. Suitable projections as
cross bar (Figs. 1, 2 and 3).
>
It will thus be seen that by a simple bending
operation of the plates, the belt end may be ade
quately secured in place to the cross bar without
the necessity for looping the belt end around said 55

bar or for stitching the looped end of the belt
in place. Preferably, the body portion 2| carries
the coplanar edge prongs 26, 21, 28 and 29 for
2. In a slide buckle, a one-piece slidable cross
bar comprising a body portion having an outer
face and an inner face and having spaced per
adequately securing the adjusted strap or belt
30 in place. The strap 30 is passed underneath
the end bars I8 and I9 but over the cross bar
forations therein, a substantially 180° bend at
each end of the body portion, and a plate ex
tending from each of said bends and arranged
I3 into the position shown in Figs. 1, 2 and 3.
When the belt is tensioned, the cross bar I3
inwardly of the inner face of the body portion
at an acute angle thereto, each of said plates
moves towards the right as viewed in Fig. 1,
having a prong thereon adapted to enter a per
10 whereby the prongs 28 and 29 cooperate with the
edge 3I of the end bar I9 to adequately secure
the belt 30 in place and to maintain it removably
in its thus secured position. Should the belt l’âlIII
be passed in the opposite direction underneath
the end bar I9,
underneath the
plied to the belt
towards the left
then over the cross bar, then
cross bar I8, then tension ap
causes the cross bar I3 to slide
as viewed in Fig. l, so that the
foration when the plate is bent into parallel rela
tion to said body portion, and each of said plates
having a length less than half the length of the
body portion.
3. In a slide buckle, a frame having parallel
side bars, and a cross bar bent about and slid
able on the side bars, said cross bar having a
bar has the function of securing the end of one
perforated portion and having a pair of opposed
plates terminating in adjacent free edges and
initially arranged at an acute angle to and at
one face of the perforated portion and having 20
prongs thereon arranged to enter the perfora
tions of the perforated portion when the plates
belt thereto adequately by a simple bending oper
ation and Without the necessity for looping or
IO 1:1 stitching the belt, said cross bar having the addi
are bent toward the perforated portion to me
chanically stitch a belt end inserted therebetween
25
to the cross bar.
prongs 26 and 21 cooperate with the edge 32 of
the end bar I8 to secure the belt in place.
It will be seen that in my new buckle the cross
tional function by reason of the prongs thereon
of cooperating with the buckle frame to secure
the other belt thereto.
It will further be seen that I have provided a
simple but efficient buckle adapted for economi
cal manufacture and adequate for the purposes
for which it is intended.
While I have shown and described certain spe
ciñc embodiments of my invention, I do not wish
to be understood as limitingl myself thereto, but
intend to claim the invention as broadly as may
be permitted by the state of the prior art and
the scope of the appended claims.
