IMPROVEMENTS IN MACHINE BELT
Year: 1886

page_text: I, WILLIAM L. TETER, of Philadelphia, Pennsylvania U.S.A., Manufacturer,
do hereby declare the nature of my invention for IMPROVEMENTS IN MACHINE
BELT, and in what manner the same is to be performed, to be particularly described
and ascertained' in and by the following statement :-
My invention has reference to woven machine belts; and consists essentially of
one or more layers of metal warp interposed between two or more layers of cotton
warp each layer being formed of two sets of warps and a suitable filling, and these
layers of warps being bound together by suitable binding warps which extend
entirely through the various layers and securely bind them together; and in details
of construction all of which is fully set forth in the following specification and
shown in the accompanying drawings which form part thereof.
I am aware that woven machine belts have been made with metallic warp, and
also metallic longitudinal strengthening strands and therefore do not here lay any
claim to the generic use of metallic warp in belting of this class, but the specific
construction of belting as herein specified, as far as I am aware, is entirely new.
The object of this invention is to form a machine helt which shall be non-
extensible in the direction of its length, and in which none of the layers of metallic
warp should come in contact with the band wheels, being thoroughly protected by
layers of cotton warp thereby producing not only a more perfect belt but one
which shall have a greatly increased durability.
In the drawings =
Fig. 1 is a longitudinal sectional elevation on line x x showing the various layers
composing the belt and how they are bound together, and
Fig. 2 is a cross section of same on line y y.
H represents layers of cotton warp and B represents layers of combined cotton
and metal warp in which E are the metal warps as is seen in Fig. 1 the layers
embodying the metal warp are separated by the layers composed wholly of cotton
warp thereby being protected from each other, and as the outer layers are of cotton
the metal warp is protected from being cut or worn by running over the pullies or
by coming in contact with external objects. D are the filling threads, and while in
practice a single filling thread is used as indicated in dotted lines, passing between
the warps of alternate layers thus binding them thoroughly together at their edges, it
is evident that each layer may have its own specific filling thread. The light dotted

page_text: lines connecting the filling threads indicated their passage at one edge of the belt
while the heavy dotted. lines indicate their passage at the other edge of the belt
showing that a strong selvage is insured. These layers H and B are firmly bound
together by the binding warps F which pass around the filling threads of the two
outer layers of the belt thus binding every layer throughout their entire surface
tightly together making the belt extremely compact and entirely protecting the
metallic portions thereof, and the peculiar construction prevents any possibility of
the metallic warp working out while the belt is in use.
Any number of layers may be employed, but in all cases the outer layers are of
cotton or fibrous material alone, while the alternate inner layers may be either
metal alone or preferably metal and cotton combined, hence the belt may be three
or more ply as desired, and in some cases that face of the belt which runs next to
the pullies may have two layers of cotton in place of one the second layer being
indicated in dotted lines in Fig. 1.
Having now particularly described and ascertained the nature of my inven
tion, and in what manner the same is to be performed, I declare that what
I claim is
1st. In a woven machine belt three or more cotton layers of warp every alternate
layer being furnished with a series of metal warp, in combination with filling and
binding threads to unite the several layers of warp to form a compact belt.
2nd. In a woven machine belt three or more cotton layers of warp every
alternate layer being furnished with a series of metal warps, and in which the two
outer layers are of cotton only in combination with filling and binding threads to
unite the several layers of warp to form a compact belt.
3rd. A machine belt composed of one or more layers of combined metallic and
cotton warp, and three or more layers of cotton warp the metallic warp being
enclosed between the cotton layers of warp and in which the wearing surface or
that which runs next to the pullies is made with a double layer of cotton warp.
4th. A machine belt composed of one or more layers of combined metallic and
cotton warp, and three or more layers of cotton warp, the metallic warp being
enclosed between the cotton layers of warp and in which the wearing surface or
that which runs next to the pullies is made with a double layer of cotton warp, in
combination with a single filling thread. which passes successively between the
warp of each layer.
5th. A machine helt consisting of the combination of the cotton warp H the
cotton and metallic warp B interposed between them, suitable filling threads, and
binding warp.
6th. In a woven machine belt one or more layers of metallic warp interposed
between two or more laye's of cotton warp in combination with suitable filling
threads and binding warp the latter passing entirely across all the layers of warp
binding them together.
