The invention relates to woven Wire fabric
and involves an improvement in means for hing

hinging units, partly broken away.
While the present improvements may be
made up as a belt. 'I‘he use of a hinge rod for
the purpose of connecting the helical coils of a
woven wire fabric is well known. It has also
been suggested heretofore that onev end of such
a hinge rod be joined to the end of an 'adjacent
hinge rod in such a manner that the rods of
successive pairs are connected together at one
end of the hinging unit. In such structures the
2 O unjoined ends of the rods which form the pairs
are free to move laterally with respect to each
other, so that the opposite edges of a belt con
structed in this manner do not have the same
ner as to be confined within the same marginal N 0
limits.- The adjacent ends of the two coils form
ing this composite structure are welded together
in one direction transversely of the belt. These
disadvantages are overcome in the present im
as shown at I2 and I3 in order to provide a rigid
coil unit in which each coil element is held
against movement with respect to the other.
A plurality of such coil units are successively
interwoven with each other to form a continuous
length in a manner well understood in the art.

thermore, such structures provide no means for
preventing endwise movement of the hinge rods
ends of successive pairs of hinge rods- so that
each of the pairs of rods forms a rigid structural
unit, and the rods are restrained against end
wise movement thereof in both directions with
respect to the belt.

Another object of the invention is the pro
vision of a wear resistant edge for wire belting,
so constructed that the wear thereon when the
belt is in use does not affect the coil elements
of which the woven fabric is made. With such
40 a structure, the wear resistant elements may be
made of a material which is more resistant to
wear than the material of the coils, and they
may be repaired or replaced at a cost much less
45
utilized with other forms of woven wire fabric
and belting made therefrom, I have illustrated
the same in the drawing in connection with a 15:
fabric in which the helical coils are of a com
posite character in that each coil element com
-prises two independent coils I0 and II of similar
structure and threaded together in such a man-_
than the cost of repairing or replacing the coils
themselves.
A further object of the invention is the pro'
Vision of a wear resistant edge for a wire belt,
so constructed that one edge of the wear resistant
50 element is positioned substantially in the plane of
one surface of the belt in order to provide a con
tinuous operating surface throughout the width
of the belt.
Still further objects and advantages of the im
55 provements will be apparent from the following
portions I4 of the turns of the coils Iii overlap U
and interengage with loop portions I5 of the coils
II in the adjacent coil unit. It will also be ap
parent that loop portions i6 of coils II overlap
and interengage with loop- portions I'l of coils
Ill in the adjacent coil unit. The loop portions 35
of adjacent coil units overlap to such an extent
as to provide openings I8 extending transversely
of the fabric for receiving hinge rods I9. As
is well understood in the art, the tension which
is exerted upon the loop portions of one of the
coil elements by an endwise pull upon a belt of
this character is transmitted through the hinge
rod, and not directly, to the interengaging loop
portions of the adjacent coil elements, to there
by provide a more flexible belt structure.
'I'he hinge rods I9 are not attached to the loops,
but extend freely through the overlapping por
tions of the adjacent coil units and are thus freely
movable with respect to the coils to provide a
flexible hinge structure. Each of the rods pro
jects outwardly beyond the opposite edges of the
fabric as shown at 20. The adjacent ends of
successive pairs of hinge rods are rigidly con
nected together by means of short bars 2l made
of wear resistant material and having the oppo
