Improvements in Woven Cartridge Belts.
I JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of
Middlesex Gentleman do hereby declare the nature of this invention (which has
een communicated to me from abroad by Thomas Corwin Orndorff residing at
No. 131 Central Street in the City of Worcester and State of Massachusetts
United States of America Manufacturer) and in what manner the same is to be
erformed to be. particularly described and ascertained in and by the following
tatement:-
This invention relates to cartridge belts made of woven material having the
pody of the belt and the cartridge thimbles or pockets woven in one piece, and has
for its object to increase the cartridge carrying capacity of the belt, without
materially increasing its bulk or weight. To this end, the invention, generally
speaking, consists in providing the belt with two layers or series of pockets or
thimbles one layer or series being outside or exterior to the other series or layer
and both being integral or woven in one with the body of the belt. It is preferred
to construct the belt so that the pockets of the second or outer layer or series of
pockets alternate with those of the first or inner layer or series the pockets of the
outer layer or series being carried by and woven in one with double ply tongues
which project outwardly between the pockets of the inner layer or series just far
enough to permit the outer pockets to seat themselves between the diverging convex
outer portions of the walls of the inner layer or series of pockets.
The nature of this invention and the manner in which the same is or may be
carried into effect will be understood by reference to the accompanying drawing in
which
Figure 1 is a perspective view of a belt constructed in its preferred form according
to this invention.
Figure 2 is a diagram drawn to an enlarged scale representing a part of the belt
in longitudinal section, the warp, weft, and binders being clearly shewn in their
relative positions in the belt and the two series of pockets.
Figure 3 is a diagramatic view similar to Figure 2 showing a modification.
The belt selected to illustrate this invention is with the exception of the additional
series of pockets, the well known Mills cartridge belt, made in accordance with the
Specification of his Letters Patent No. 5393 dated December 23rd 1880.
The two thicknesses of fabric which compose the belt are shewn in Figure 2, the
warp threads of the inner ply or thickness are marked a the weft threads of
the said inner ply or thickness being marked b. The warp threads of the outer
ply or thickness are marked c and the weft threads of the said outer ply or thickness
are marked d. The two series of binders which hold together the two plys or
thicknesses and cause them to form one fabric are marked ef. The thimbles or
pockets C are formed by the warp c and weft d of the outer ply and extend only
part way across the belt leaving at each edge a selvage composed of the full
thickness of the double fabric. The warp and weft of the inner ply do not enter
into the composition of the thimbles.
Thus far there is nothing new in the belt, it being substantially the same as that
described and claimed in the Specification of Letters Patent No. 5393 dated
5 23rd December 1880 herein before referred to.
According to the present invention as shewn in Figures 1 and 2, there is formed
in addition to the ordinary series of pockets C another series of pockets D which
alternate with the pockets C and form a layer of pockets exterior to the first layer.
In the belt shown in these figures, each pocket D is woven in one with and is
50 carried by a double or two ply tongue E of fabric which is in one with the outer

page_text: ply of the belt, and extends out between contiguous pockets of the first or inner
layer of pockets C.
This result is produced by means of the binders f which in the weaving are
carried into the fabric of which the two plies of the tongues E are composed.
The binders are carried by a separate warp beam from the binders e.
Usually in the weave there are twelve binders e and twenty-four binders f each
set of binders having its own separate warp beam and harness.
Both sets of binders e and f enter the fabric of the body of the belt but neither
set enters the fabric of the pockets C and the binders alone enter the fabric of
which the tongues E are composed but are omitted from the outer pockets D.
Thus during the weaving of the pockets C, both sets of binders are thrown out
of the weaving.
When however the tongues E are being woven, the binders e are
thrown out of the weaving, but the binders f continue in until the fabric composing
the first ply of any one tongue is completed; then they are thrown out of the
weaving (at the point i) while the fabric of the pocket D is being woven; and
then when this last named fabric has been woven of the proper length for the pocket,
the binders fare again brought into the weaving, thus uniting the ends of the
pocket fabric at the point i, and continue in the weave of the second ply of the
tongue E, until that has been completed, when the binders e are also thrown in and
the weaving of the body of the belt proceeds.
Inasmuch as the tongues E are composed of two plies joined only at their
outer and inner ends, they are in effect tubes which might serve as the inner layer
of thimbles or pockets. Such a construction is represented in Figure 3. The
only differences between the belt shown in this figure and that in Figures 1 and 2
-(1) the pockets C are dispensed with (2) the two plies of each tongue are so
proportioned as to form a thimble or pocket (distinguished by the reference
letter C') of the dimensions required for the cartridge and (3) these pockets (C¹)
are brought as close together as they would be in a Mills" cartridge belt having
only a single layer of pockets.
are-
It will be seen that in this belt as in that illustrated in Figures 1 and 2 two
layers of pockets are woven in one with the body of the belt, and that the binding
warps which define the limits of, and close, the pockets of the outer layer on the
side next to the belt are omitted from the fabric of the outer pockets. In this
form of belt a greater number of pockets may be formed since the interval between
adjoining pockets of the inner layer (usually about an eighth of an inch) required
for the tongues E in the arrangement Figures 1 and 2 is not necessary in the form
of belt shewn in Fig. 3. The advantage thus gained is however counteracted by
the increased thickness of the belt as a whole-the belt shewn in Figure 3
necssarily being thicker than that in Figures 1-2 where the pockets of the outer
layer are partly contained and held in the spaces between the outer portions of the
pockets of the inner layer.
Although the invention has been described as applied to Mills double ply woven
cartridge belt it is not restricted thereto as it is evident that with such modifi-
cations of weaving mechanism as will readily suggest themselves to the skilled
workman, it may be applied to a single ply woven belt, or to a woven belt, whether
single ply or multi-ply in which the pockets extend the full width, instead of only
part of the width, of the belt.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. A woven cartridge belt, having two layers of pockets or thimbles woven in
one therewith, the pockets of the outer laver alternating with those of the layer
next to the body of the belt, and being carried by tongues extending outwardly
between the pockets of the latter layer substantially as herein before described.
2nd. A woven cartridge belt having two layers of pockets or thimbles woven in
one therewith the pockets of the outer layer being carried by and formed in one

page_text: with tongues projecting outwardly between the pockets of the inner layer and
consisting each of two plies or thickness of fabric joined at their outer extremities
by auxiliary binding warps which are omitted from the fabric of the outer pockets
substantially as hereinbefore described.
3rd. A woven cartridge belt having two layers of pockets or thimbles woven in
one therewith the pockets of the outer layer being completed by binding warps
which enter into the fabric of the belt but are omitted from the fabric of
which the body of the outer pockets is composed, substantially as hereinbefore
described.
