1, SAMUEL ROWBOTTOM of Glossop in the County of Derby, Cotton Spinner, do
hereby declare the nature of my said Invention for "IMPROVEMENTS IN DRIVING-
BELTS," to be as follows:
My invention relates to belts for driving all kinds of machinery and consists in
making the said belts of woven belting combined with leather, in the manner herein-
after described.
For heavy belts I use two woven belts of cotton, wool, worsted or other suitable
material or combination of materials, and of suitable width and thickness. Between
the said belts and extending throughout their length is inserted leather of suitable
thickness and wider than the said belts, and the said leather and woven belts are
secured together by cementing, stitching or rivetting in such a manner as to leave an
equal portion of the leather extending beyond each edge of the woven belts.
If one
thickness of leather is insufficient, two or more may be used. Another strip of leather
is placed on each side of the projecting edges or portions of the inserted leather.
Each of the said strips is of the width of the extending edges or portions of the
inserted leather and of the same thickness as each of the woven belts. The said strips
and inserted leather are secured together by cementing, stitching or rivetting when
the whole forms a leather-edged belt of equal thickness throughout.
For light belts I take leather of suitable width (say three inches) and cut or rasp
out a portion of its width (say two and a half inches) and say one third of the thickness
of the leather from the centre of each side or surface thereof, thus forming a central
longitudinal groove on each side of the leather, and leaving one third of the thickness
of the leather between the said grooves. I then place a light woven belt of cotton,
wool, worsted or other suitable material or combination of materials in each of the
said grooves, each of the said woven belts being of sufficient thickness and width to
Pi

page_text: exactly fill the groove in which it is placed. The whole are then cemented, stitched or
rivetted together as before stated thus making a leather-edged belt of equal thickness
throughout.
I also make heavy belts in the manner herein before described for making light belts.
In making heavy belts if two thicknesses of leather are required to make up the
desired substance of the belt I cut or form a groove of the required width and depth
in one side only of each leather and cement the two strips of leather together by their
backs or ungrooved sides. The woven belts are then inserted in the grooves and the
whole secured together in the manner hereinbefore described.

I, SAMUEL ROWBOTTOM of Glossop, in the County of Derby, Cotton Spinner do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following state-
ment, reference being had to the accompanying drawing forming a part of this
specification
:-
My invention relates to belts for driving all kinds of machinery and consists in
making the said belts of woven belting combined with leather, in the manner herein-
after described.
:
For heavy belts I use two woven belts of cotton, wool, worsted or other suitable
material or combination of materials, and of suitable width and thickness. Between
the said belts and extending throughout their length is inserted leather of suitable
thickness and wider than the said belts, and the said leather and woven belts are
secured together by cementing stitching or rivetting in such a manner as to leave an
equal portion of the leather extending beyond each edge of the woven belts. If one
thickness of leather is insufficient two or more may be used. Another strip of leather
is placed on each side of the projecting edges or portions of the inserted leather. Each
of the said strips is of the width of the extending edges or portions of the inserted
leather and of the same thickness as each of the woven belts. The said strips and
inserted leather are secured together by cementing stitching or rivetting, when the
whole forms a leather-edged belt of equal thickness throughout.
For light belts I take leather of suitable width (say three inches) and cut or rasp
out a portion of its width (say two and a half inches) and say one third of the
thickness of the leather, from the centre of each side or surface thereof, thus forming
a central longitudinal groove on each side of the leather, and leaving one third of the
thickness of the leather between the said grooves. I then place a light woven belt of
cotton, wool, worsted or other suitable material or combination of materials in each of
the said grooves, each of the said woven belts being of sufficient thickness and width
to exactly fill the groove in which it is placed. The whole are then cemented, stitched
or rivetted together as before stated, thus making a leather-edged belt of equal
thickness throughout. Or one groove in the leather may be cut deeper than the other
so as to admit a stouter and stronger woven belt to be secured therein on the working
side or face of the belt.
I also make heavy belts in the manner hereinbefore described for making light
belts. In making heavy belts, if two thicknesses of leather are required to make up
the desired substance of the belt, 1 cut or form a groove of the required width and
depth in one side only of each leather and cement the two strips of leather together
by their backs or ungrooved sides. The woven belts are then inserted in the grooves
and the whole secured together in the manner hereinbefore described, either cemented,
stitched or rivetted with any kind of metallic substance, or any kind of wooden pegs.

page_text: The drawing illustrates various modes or methods of constructing my improved
driving-belts.
Figure 1 is a transverse section and Figure 2 is a view of one side or face of a
portion of one of my improved belts. a a are woven belts of cotton, wool or other
suitable material and of suitable length, width and thickness between which and
extending throughout the length of the belt is inserted the leather whose edges
project from the edges of the woven belts, as shown. The woven belts a a and leather b
are secured together by pegs or rivets c or in any other suitable manner. Upon the
upper and lower sides or faces of the projecting portions 6 of the leather bare secured
strips of leather d, each of the width of the said projecting portions 61 and of the
thickness of the woven belts a a. These strips & are secured to the projecting ends b
by rivets e or by cementing or other suitable means, the whole then forming a leather-
edged belt of equal thickness throughout. Two or more thicknesses of leather 6 may
be inserted if one thickness is insufficient. This method of construction is adapted
for heavy belting.
Figure 3 is a transverse section and Figure 4 a side or face view of a light belt.
The leather b, of suitable width and thickness (say three inches wide) has cut or rasped
out a portion of its width (say two and a half inches) and say one third of its
thickness from the centre of each of its sides or faces, thus forming a longitudinal
groove on each side or face, and leaving one third of the thickness of the leather
between the said grooves. A woven belt a of cotton or other suitable material is then
inserted in cach of the said grooves, the said woven belts being of sufficient width and
thickness to exactly fill the said grooves, and they are secured therein by pegs or
rivets c, or by cementing, or other suitable means.
Figure 5 is a transverse section of another form of light belt, in which the grooves
in the leather bare formed of unequal depth, one being deeper than the other in order
to receive a stouter and stronger woven belt a¹ for the working face of the belt.
a
Figure 6 is a transverse section showing another mode or method of making
heavy belt. Two thicknesses of leather 62 63 are employed, each having a longitudinal
groove of the required depth in the centre of one side thereof. The two strips of
leather are then cemented or otherwise secured together by their backs or ungrooved
sides. The woven belts a a are then inserted in the grooves and the whole secured
together by pegging, rivetting or other suitable means.
I do not limit myself to the precise modes of construction herein described, as the
same may be varied without departing from my invention, but,
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
Leather-edged driving belts, substantially as herein set forth and illustrated by the
accompanying drawing.
