"IMPROVEMENTS IN THE MANUFACTURE OF BELTING
"
This Invention which relates to Improvements in the manufacture of belting has
reference to belting made of canvas or cotton and woven belting generally also to
felted belting as well as to what is sometimes known as paper belting and it has
for its object to render such belting more durable and that without destroying the
flexibility thereof.
In such belting as hitherto made it has been the practice to sew the same with
cotton or other fibrous sewing,
According to the present Invention the belting is sewn with copper wire, or brass
wire, or steel wire, or aluminium bronze wire, or wire of other suitable metal and
such belting may be wholly sewn with such wire, or with such wire in rows
between which the sewing of cotton or other textile or spun material is, or may be,
interposed.
Besides rendering such belting more durable, in the sense that the metallic copper,
or other wire, bearing against the pulley prevents the woven or felted material, or
paper, from being so quickly worn as hitherto, it also prevents the sewing from
becoming undone and the belt coming to pieces as under the existing modes of
manufacturing the same.
Under a modification of this Invention instead of sewing the material together
by copper or other wire it may be held together by screwed studs of metal passed
through the layers of the said material and rivetted over on each side.
Another part of the present Improvements has for its object to prevent the sides
or edges of belting of the kinds hereinbefore described from being worn or
[Price 6d1

page_text: destroyed by the action upon the said edges of the shifting fork by which the
aforesaid belts are moved from and to the fast and loose pulleys respectively which
they are caused to run upon. This object is effected by attaching to each edge of
such belts a strip of leather which may either be sewn down upon the outer face
of the said belts or between the layers of woven or felted material, or paper, of
which the said belts are composed and in either case projecting sufficiently far
beyond the edges of the woven or felted material, or paper, so that the leather
itself forms a shield to the said edges and thereby prevents the fork from coming
into contact therewith. The strips of leather at the edges of the said belt may be
sewn thereto by copper or other wire, or by other suitable mode of attachment.

"IMPROVEMENTS IN THE MANUFACTURE OF BELTING
"
My said Invention relates to Improvements in the manufacture of belting, and
has reference to belting made of canvas or cotton and woven belting generally
also to belting known by the following designations: "cotton-canvas belting,"
"solid cotton woven belting" "camel-hair-belting" "linen, hemp and jute belting
made either in several plies or of one thick ply, gutta-percha belting," belting
made of india-rubber or india-rubber and cloth, "felted belting" and belting made
of paper.
"
My Invention has for its object to prevent the sides or edges of belting of the
kinds hereinbefore described from being worn or destroyed by the action upon
the said edges of the shifting fork by which the aforesaid belts are moved from and
to the fast and loose pulleys, respectively, which they are caused to run upon.
This object is effected by attaching to each edge of such belts a strip of leather,
which may either be sewed down upon the outer face of the said belts or between
the layers of woven or felted material or paper of which the said belts are
composed, and in either case projecting sufficiently far beyond the edges of the
woven or felted material or paper, so that the leather itself forms a shield to the
said edges, and thereby prevents the fork from coming into contact therewith.
The strips of leather at the edges of the said belt may be sewed thereto by copper
or other wire or be fastened thereto by other suitable mode of attachment.
In the drawings Figures 1, 2, and 3, represent respectively, in plan, transverse
section and in side elevation a portion of belting constructed according to and
constituting a part of my present invention. Figures 4, 5 and 6, represent
respectively corresponding views of a modified form of the same.
The belting, with a view to enhancing its durability is sewed as represented
at a, Figure 1, with copper, brass, steel or aluminium bronze wire, or with wire of
any other suitable metal, and the said belting may be wholly sewed with such
wire or with such wire in rows, between which the sewing of cotton or other
textile or spun material is or may be interposed.
The belting, instead of being sewn together with copper or other wire, may be
held together by screwed metal studs b, Figures 4, and 5, passed through the layers
of the material forming the belting and riveted over on each side.
I now proceed to describe my improvement, which as above stated, has for its
object to prevent the sides or edges of belting, of the kinds herein before described
from being worn or destroyed by the action upon the said edges of the shifting
fork by which the aforesaid belts are moved off from and on to the fast and loose
pulleys respectively upon which they are caused to run. This object is effected, as
represented on the accompanying drawings by attaching to each edge of the belt c,
a strip d, of leather, which may either be sewed down upon or otherwise suitably
secured to the outer face of the said belt c, as represented at Figures 1, 2, and 3,
or it may be inserted into the edges of such belt, as represented at Figures 4, 5,
and 6, wherein it is secured by sewing or by any other suitable means. In either
of these cases the leather strips d, project out from or over the edges of the belting,
so that the leather forms a shield to the said edges and thereby prevents the fork
from coming into contact with the said belting.
The strips d, of leather, although shewn on the accompanying drawings as
secured to or into the edges of the belting by the wooden pegs e, and copper

page_text: rivets f, the latter of which are bent over at their ends for the purpose of being
secured therein, may be sewed thereto or thereinto with copper or other metallic
wire or by any other suitable mode of attachment.
Having now described and particularly ascertained the nature of my said
Invention and the system, mode, or manner in or under which the same is or may
be used or practically carried into effect I would observe in conclusion that what
I consider to be novel and original and therefore claim as the Invention secured to
me by the herein before in part recited Letters Patent is
First. The combination, with the body of the belting of separate leather strips
applied to the longitudinal edges of the belting so as to project laterally beyond
the same, substantially as and for the purposes herein before set forth.
Second. The combination, with the belting of separate strips of leather inserted
and secured in or between the longitudinal edges of the belting, so as to project
laterally beyond the same, substantially as and for the purposes herein before set
forth.
In Witness whereof I, the said John Keil Tullis have hereunto set my hand
and seal this twelfth day of March in the year of our Lord One Thousand eight
hundred and eighty four.
