Fabric for Belting.
1, JOSHUA PERKINS MADDOX, of No. 172, Newbury Street, in the City of Portland,
in the County of Cumberland, and State of Maine, United States of America,
Mechanic, do hereby declare the nature of my invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement and accompanying drawings
:-
My invention relates to a fabric for belting having metal wires extending longitudi“
nally through it for the purpose of increasing the strength of said fabric.
Fabric for belting has been made with a number of plies of fibre having a straight
or nearly straight central wire and binder wires extending through from one face to
the other. Wire warps have also been used for the alternate plies of a multiple ply
fabric.
By actual trial and experiment in the manufacture of such belting it has been found
very difficult to make a perfect belt when wire is laid in the fabric, straight or
nearly so.
In weaving fabric of this description it is found to be a very difficult matter to secure
uniform tension on the longitudinal wires at all times, and when laid or woven into
the belt so that they lay straight, or nearly so, they are nearly or quite devoid of
elasticity, and a uniform strain exerted on the belting is liable to break those wires that
are put in with the highest tension.
This difficulty is particularly encountered when the belts run over small pulleys
where they are subject to frequent changes of tension.
The object of my invention is to produce a fabric wherein the wire used shall be
used as a binder warp to bind solidly together the central plies, at the same time pro-
ducing in it a corrugation which gives it a limited amount of elasticity in the direction
of its length.
My invention consists of a fabric having several central plies bound together with a
wire warp which passes through them from one side to the other, and facing plies
secured to said central plies by fibre binders.
In the accompanying drawing I represent a fabric which embodies my invention.
In the drawing:
:-
Fig. 1 represents a longitudinal section through my belt fabric.
Fig. 2 is a cross section.
I have here shown a fabric composed of six plies, two outer or facing plies A A, and
four inner central plies B B. The four central plies I have shown as bound together by
a wire warp E, which passes back and forth through them binding them solidly
together, a representing the ordinary warp and 6 the weft.
The facing plies are bound to the body of the fabric, as here shown by fibre binders
which extend from one face to the other of the fabric.
As thus woven my fabric contains a series of metal wire binders which bind firmly
together the central plies, and strengthen the fabric longitudinally, and which have a
imited amount of elasticity in the direction of the length, so that any small inequalities
of tension will not cause a break of the wire.
It is evident that I may vary the number of plies in my fabric uniting two or more
nterior plies by my wire binder and tying to them the facing plies by means of fibre
binders which may not in all cases extend from one face to the other.
The facing plies are laid in such a manner as to produce a surface of fibre on each
ace of the fabric.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed 1 declare that what
I claim is :-
―
1. The herein described material for belting, consisting of two or more interior plies
having binding wires extending back and forth through their entire thickness, and
the facing plies joined to said interior plies, substantially as set forth and indicated.
Dated the 27th day of January 1890.
