BALE BAND BUCKLE
Ezra A. Frantz, Weatherfcrd, Tex.
Application February 9, 1937, Serial No. 124,911
1 Claim. (Cl. 24——23)
This invention relates to improvements in fas
tening devices and, particularly, to buckles or ties
for securing the ends of the bale bands used in
‘
the baling of cotton or other materials.
5
' _
One object of the invention is to simplify the
construction of the buckle and, consequently, the
procedure necessary to form up the buckle, thus
minimizing production costs.
‘
Another object is to provide a buckle in which
10 the ends of the bale band are securely held against
slipping or creeping without imposing on said
ends strains which will be apt to shear the latter.
In the present instance, the buckle is formed with
an opening through which the band ends are in
' serted with said ends engaging opposite walls of
the opening and one or both of said opposite
walls are so formed as to effect .a transverse dis
tortion of the metal of the band end. However,
this distortion is limited to a portion of the band
20 spaced from the side edges.
In the preferred
construction, one or both of the band engaging
edges of the buckle opening are formed with an
intermediate dished portion and straight end
portions but the length of said dished portion is
less than the width of the band.
As a result, the
straight portions of said band-engaging edge or
edges do not distort the band but the latter is dis
torted at its intermediate portion only by the
dished portion of the edge of the buckle opening.
30
A still further object is to provide a buckle
which, together with the band ends, can be read
ily assembled on a compressed bale and which
when the pressure on the bale is released, will
cause one band end to be bent in reverse direc
35 tions, this bending of said end being accomplished
solely by the strains imposed upon the band and
buckle during expansion of the bale after release
of said pressures.
'
With these and other objects in View, the in
40 vention consists in certain details of construction
and combinations and .arrangements of parts, all
as will hereinafter be more fully described and
the novel features thereof particularly pointed
out in the appended claim.

'
In the preferred embodiment of the inven 10
tion, thebuckle .or tieis stamped out of a metal
blank, the blank being stamped to form an open
ing It into which the ends l1, l2 of the bale band
are inserted from what, for convenience, may be
termed the outer side of the buckle. In forming
the opening Iii, the central portion of the blank
is not detached but is bent inwardly and consti
tutes a tongue l3. As illustrated, the buckle may
be said to consist of upper and lower cross bars
I4, I5 and ends it, with the tongue l3 projecting
inwardly from upper bar M. In applying the
band and buckle to a bale, the band is placed
around the bale and the ends thereof inserted
in opening I I] while the buckle is held more or
less at right angles to the surface of the bale. As 25
will be understood, the bale is under compression
at this time. When the ends are inserted with
the buckle in this position, the band end II is
bent around the tongue l3 as shown in Fig. 3.
If desired, this end ll may be attached to the
buckle before placing the band around the bale.
In either event, when the end I2 is inserted, it
bears against both the edge of the opening along
lower bar l5 and the surface of the band around
the edge of tongue l3, so that the tongue may be
said to impinge against both ends of the band.
The frictional engagement of end l2 with the
buckle and tongue is such that when the pressure
on the bale is released and tension placed on the
band, said end It will not slip but, on the con 40
trary, the buckle will be caused to turn .and as
sume the position shown in Fig. 4. This turning
motion of the buckle will result in reverse bends
being produced in band end l2 by the edge of
lower bar l5 and the edge of tongue l3, the band 45
also being pressed into the bale by said tongue.
This form of buckle thus greatly facilitates
applying and securing the band around the bale
'in that one end of the band I2 in the present
instance does not have to be bent by the opera—
tor, but is automatically distorted by the buckle
during tensioning of the band, as just described.
In order to prevent subsequent creeping of the
band on the buckle, the edge of lower bar I5
against which band end I2 engages, may be
2

formed with a dished or concave portion [1. This
It will be seen that either form of buckle can
curved portion causes the band to be further
distorted when tensioned on the bale, this dis
be produced at a very-low cost. A minimum
amount of material can be used in forming the
buckle and the operations required to be per
tortion being best described as taking place
transversely of the band. However, to reduce
shearing of the band and excessive transverse
formed on the blank are few and inexpensive. If
desired, depending upon the use to be made of
deformation, this dished or concave formation
the buckle, a comparatively light-weight metal
of the edge of lower bar 15 is limited to the inter
mediate portion of the bar, the edge of said bar
10 at the ends of opening l0 being straight. As .a
result, an intermediate ‘portion only of band end
I2 is distorted by being pulled down, so to speak,
into the intermediate concave portion of the
buckle bar. This crimping or transverse'de
15 formation by the dished portion I‘! insures an
e?ective binding of the band end in the buckle,
can be used in the buckle. For instance, as illus
trated in Fig. '7, a buckle can be made light
' the binding action increasing with the tensioning
of the band. At the same time, unusually Jheavy
-strains will not shear the hand because thepro
vision of straight edges at the ends of bar t5
.limits the deformation :or crimping (of the iband
to an intermediate portion thereof.
In theffcrm 10f buckle illustrated in Figs. '5 to
‘.7, the central .portion :of :themetal blank is re
25 moved in stamping out the opening 10, thus
enough to permit its being ‘elongated by the 10
strains transmitted thereto iby the tensioned
band. This elongation of the buckle increases
the curvature of the dished portions I‘! and this,
in turn, increases the transverse deformation of
=the'band and the security of attachment of its 15
ends -to the buckle.
‘If desired, the edges of the buckle bars l4, 15,
can be ‘beveled slightly and, in the buckle of
Figs. .1 to 4, a slight enlargement i8 may be left
on the edge of tongue I3 to eifect a transverse 20
deformation-of the band ends.
What I claim is:
.
' A bale-band buckleof sheet material substan
tially rectangular in 'shape'having {asubstantially
rectangular opening ‘extending therethrough,
eliminating'ithe tongue l3. Onetheother hand,
however, ‘both :the ‘upper and lower :bars 14, I5,
