6 Claims.
, This invention relates to improvements in end
loop construction for‘band chains and steel
tapes.
I
‘
It has been proposed to provide an end loop
‘ construction of a reversely bent ribbon of metal
between the extremities of which the end of the
band chain or tape is disposed and clamped as
by rivets. Such construction has been found to
_ possess the common fault that vthe band or tape
breaks at the edge of the extremity of the end
loopv because of the fact that one portion of the
tape is held rigidly between the extremities of the
end loop while the rest of the tape is free to ?ex
with respect thereto. >

It ‘is an object of this invention to overcome
the tendency of the band chain or tape to break
at the edge of the end loop. Accordingly, the
bending of the band chain or tape at the edge
of the end ‘loop is retarded. More particularly,
20
this retardation is‘ accomplished by yieldingly
opposin‘gthe bending, preferably by yieldingly
engaging the band or tape for a short distance
from the edge of the end 1001).
Another object of the invention is to facilitate
25 the passage of the end of a band chain or tape
through the brush as when it is ‘dragged along
the ‘ground. In carrying this aspect of the in
vention into ‘effect, strips of spring steel are se
cured vupon opposite sides of the band or tape
so
where itgis engaged between the‘ extremities of
the, end loop and these resilient strips extend
beyond the extremities of the end loop and are
bent at theirT’endstoWard-the band or tape so
as to normally engage the same only by their
35 end edges. The tape can thus be ?exed in either
direction and at all times the free ends of the
resilient strips will be in contact with the tape.
These and other objects of the invention and
the means for their attainment will be more
40 apparent from the following detailed descrip
tion, taken in connection with the accompanying
operation of the spring members in opposing
the flexing of the tape; and‘
Figure 6 is a View in side elevation showing
another modi?cation of the invention.
For convenience, a band chain or any other 5
ribbon of steel'or equivalent material, the break
ing of which is to be prevented at its juncture
with a relatively in?exible part will hereinafter '
be termed a tape.
In one modi?cation of the invention, the end
loop is conveniently stamped or otherwise formed
from a strip of metallic material havinga cross
section such as indicated at the end 5 of the
member shown in Figure 1. Intermediate its
ends, the edges are conveniently out out, as at 15
6, and thereafter holes ‘I are formed for the rivets
8 (Figure 3). The end loop is then reversely
bent so that the extremities 9 are adjacent to
each other in spaced relation with the holes ‘I
in register.
In one simple form of the invention, as shown
in Figure 3, two spring pieces ll), each conven
iently of a plane strip or ribbon of resilient ma
terial, such as steel, are provided, each of a
width substantially that of the tape ll.
One
end of each of theserspring strips it is formed 25
with holes (not shown) adapted to register with
theholes '! of the end loop 5—9. The end Iii of
the'tape I1 is inserted between the extremities 9
of the end loop and the perforated end‘ of a
strip I0 is interposed on each side between the 30
tape end it and the extremity 9 and secured
tightly together by means of the rivets 8, as
shown ‘in’ Figure 3.
The length of the spring
pieces Ill is so selected that the pieces ill extend
beyond the ?xed edges 5 a sui?cient distance to
yieldingly oppose bending of the tape about the
abutment 5 where an unreeni‘orced tape fre
quently breaks.
.
drawing illustrating embodiments by which the
inventionnmay be realized and in which:
In some situations when the tape is ?exed to
one side with respect to the end loop, the spring
end I!) on the side opposite that toward which
the tape is ?exed will stand out straight (in a
Figure 1 is a view in perspective showing the
plane) and may catch in twigs or bushes as the
45 end loop of a steel tape in one of the stages of
its manufacture;
V
Figure 2 is a perspective view showing one of
the pieces of spring steel which is used to oppose
the breaking of the tape;
50
(01. 33-137)
Figure 3 is a side view of one form taken by
the invention in which the pieces opposing break
ing of the tape are plane members;
Figure 4 is a perspective view showing the parts
of Figures 1 and 2‘ in assembled position;
Figure 5 is a View in side elevation showing the
55
tape is moved along through the brush. In the 45
construction shown in Figures 2, 4 and 5, this
possibility is obviated.
Two spring pieces I l are formed as shown in
Figure 2 each conveniently of a strip of resilient‘
material, such as steel. One end of a spring piece 50
I I is preferably bent upwardly on a curve, as
shown at [3. It is provided with holes l5 adapted
to register with the holes. ‘i of the end loop 5-9.
The end 16 of the steel tape II is inserted be
tween the extremities 9. This end I6 is also 55
2,105,149
2
perforated with holes, not shown, to register with
the holes ‘I of the end loop. On the opposite
sides, between the tape IT and the respective ex
tremities 9, are disposed the spring members ll
so arranged that the ends l3 are de?ected toward
the tape. When the extremities 9, leaf springs I l
and the tape end 16 are clamped tightly together
by means of the rivets 8, as shown in Figure 3,
the spring pieces II will yieldingly'engage the
10 tape for a distance from the edge of the end loop.
The curved spring ends 13 will be so disposed
as to be de?ected or bowed outwardly from the
tape IT to engage the tape substantially only
at their ends “I.
It will be readily apparent that when the tape
H is ?exed, as shown in Figure 5, the spring end
I3 on the side toward which the tape is ?exed
will yieldingly oppose the ?exing and cause the
tape to bend on an arc of relatively long radius,
20 thus preventing the tape from making a sharp
angular bend at the edge 5 of the end loop ex
tremity 9 which might cause it to break on that
line, while the spring end l3 on the opposite side
will follow the contour of the tape as it ?exes
and no opening will ever be present between a
spring end l4 and the tape ‘I, in which twigs,
brush, grass, wire or other obstruction can be
caught.
The resilient members opposing or retarding
30 ?exing of the tape need not necessarily be formed
as separate elements. An end loop 20, which may
be made of a material which when in thin plates
has the desired degree of resiliency, is shown
in Figure 6. The extremity portions 22 are rela
tively rigid because of their thickness, while
spring-like ?exible portions 24 protrude there
from.
The tape end 16 is clamped between the
rigid portions 22 by rivets 8.
40
The portions 24
extend a su?icient distance beyond the rigid por
tions 22 and yieldingly engage the opposite sides
of the tape I‘! to oppose ?exing proximate the
thicker portions 22.
Various modi?cations will occur to those skilled
in the art in the composition, con?guration and
45 disposition of the instrumentalities by which
the tape is prevented from breaking at or
about the plane of the edge of the rigid part as
well as in the use to which the invention may be
put, and no limitation is intended by the phrase
50 ology of the foregoing description or illustrations
in the accompanying drawing, except as indi
cated in the appended claims.
