Improvements in the Manufacture of Raw Hide and other Belting.
I, SIMON SCHREIBER, of 164 Fenchurch Street, in the City of London,
Merchant, do hereby declare the nature of this invention to be as follows:-
My invention relates to the manufacture of raw hide and leather belting such
as is employed for communicating motion in machinery; and my said invention
is designed to increase the strength and durability of such belting, more especially
at the edges and joints thereof.
It is well known that the belts or bands used for communicating motion from
one wheel or pulley to another, wear more rapidly at the edges, than along the
middle, and that the edges of such belts or bands are liable to injury by the
action of belt-shifters when such are employed.
In some instances, belts have been made of two or more thicknesses or bands
of raw hide or leather cemented, stitched or riveted together. Such belts are,
however, liable to open or separate at their edges especially when frequently
subjected to the action of a belt-shifter, as, for example, in machines wherein the
frequent shifting of a belt is effected automatically.
By my invention, I am enabled to make a belt or band which is much stronger
and more durable at the edges than those of like thickness or quality heretofore
employed and which is adapted for use with the ordinary wheels or pulleys.
In making my improved belting, I take a piece of raw hide or of leather of
suitable thickness and of greater width than the belting to be made therefrom,
and I fold the raw hide or leather upon itself along both edges thereof so that
each edge of the belt is solid and of double thickness, the folds being presented
to the action of the belt-shifter. I can secure the two thicknesses of the material
together by means of cement or by stitching, or both, or by riveting or the like.
If necessary I cut suitable slits or channels along the lines where the raw hide
or leather is to be folded, so as to facilitate the folding thereof.
I find it advantageous to fold the material so that the edges thereof abut or
nearly abut against each other about the middle of the belt, and to secure the
parts which are folded over to the main or middle portion first by means of cement
or other suitable adhesive material and then by two or more rows of stitching.
It is evident that, in this mauner, I can produce belting as strong and durable as
that hitherto employed, from raw hide or leather of much less thickness, or I can
produce belting of much greater strength and durability than that heretofore used,
by employing raw hide or leather of equal thickness.
In joining the ends of the belting, or of two pieces of belting, I first unite the
said ends by means of cement or the like, and I then fold the material upon itself
along the edges thereof and secure the folded-over parts by means of cement or
the like, and by stitching. The stitching serves to unite the two ends in a very
strong and durable manner. This mode of joining the ends is very advantageous,
as one end of the joint is completely covered, and the end which is not covered is
turned or folded over at the edges of the belt. There is therefore much less
liability to injury to the joint than is the case with the ordinary joints of belting.
I sometimes take raw hide or leather of about twice the width of the belting to
be made therefrom, so that when the edges thereof are folded over they will meet

page_text: or abut against each other along the middle of the belt, or so that the edges will
more or less overlap one another, in which case the edges are preferably bevelled
and united by means of cement or in any other convenient manner.
In some instances I make belting of greater thickness by inserting one or more
additional strips or plies of raw hide, leather or other suitable material between
the middle portion of the piece or strip of raw hide or leather and the parts
thereof which are folded over upon the same. Or I can use two or more
thicknesses or plies of raw hide or leather of greater width than the belting to
be made therefrom, and then fold over the edges of all of the said plies.
It may be advantageous to stitch the plies together along the edges or near
the edges of the belting.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Raw Hide and other Leather
Belting.
I, SIMON SCHREIBER, of 164 Fenchurch Street, in the City of London,
Merchant, 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 statement:-
My invention relates to the manufacture of raw hide and other leather belting
such as is employed for communicating motion in machinery; and my said
invention is designed to increase the strength and durability of such belting, more
especially at the edges and joints thereof.
It is well known that the belts or bands used for communicating motion from
one wheel or pulley to another, wear more rapidly at the edges than along the
middle, and that the edges of such belts or bands are liable to injury by the action
of belt-shifters when such are employed.
In some instances belts have been made of two or more thicknesses or bands of
raw hide or other leather cemented, stitched or riveted together. Such belts are,
however, liable to open or separate at their edges, especially when frequently
subjected to the action of a belt-shifter, as, for example, in machines wherein the
frequent shifting of a belt is effected automatically. Moreover the joints or laps
of such belts are liable to be opened or otherwise injured by the action of the
belt-shifter.
By my invention I am enabled to make a belt or band which is much stronger
and more durable at the edges than those of like thickness or quality heretofore
employed, and which is adapted for use with the ordinary wheels or pulleys. By
my invention I am, moreover, enabled to make a joint between the ends of the
belt or belts in such a manner that any risk of detachment or displacement of
the ends is entirely prevented.
In the accompanying drawing.
Figure 1 is a cross section, and
Figure 2 a plan of a portion of a belt of double thickness made in accordance
with my said invention.
Figure 3 is a plan showing the joint of such a belt.
Figure 4 is a cross section showing another form or modification of my
invention.

Figure 6 a cross section of a belt made therefrom, illustrating another-
modification of my said invention.
Figures 7, 8 and 9 are cross sections, and
Figure 10 a plan illustrating further modifications of my invention.
Figures 11, 12, 13 and 14 are cross sections illustrating still further modifications
thereof.
In making my improved belting, I take a piece a of raw hide or other leather of
suitable thickness and of greater width than the belting to be made therefrom, and
I fold the raw hide or other leather upon itself along both edges thereof so that
each edge of the belt is solid and of double thickness, the folds being presented
to the action of the belt-shifter. I can secure the two thicknesses of the material.
together by means of cement, or by stitching as shown, or by both cementing and
stitching or by pegging, lacing, riveting or the like.
In the belts shown in Figures 1, 2 and 3, and in Figures 5 and 6, the material
is folded so that the edges thereof abut against each other about the middle of
the belt, as at e, or so that they very nearly abut against each other, and the
parts which are folded over are secured to the main or middle portion first by
means of cement or other suitable adhesive material and then by two or more
rows d of stitching.
It is evident that, in this manner, I can produce, from raw hide or other
leather of much less thickness, belting as strong and durable as that hitherto
employed, or 1 can produce, from raw hide or other leather of equal thickness,
belting of much greater strength and durability than that heretofore used.
In Figures 5 and 6 I have shown a modification of my invention in which I cut
slits or channels along the lines where the raw hide or other leather is to be
folded, su as to facilitate the folding thereof, Figure 5 showing the strip a before
the edges are folded over and Figure 6 the finished belt.
In joining the ends of the belting or of two belting strips, I first scarf the
ends of the belting in the usual manner, before the edges have been folded over,
and then unite the said ends by means of cement or by stitching or the like; I then
fold the material upon itself along the edges and secure the folded-over parts by
means of cement or the like, and by rows d of stitching as shown in Figure 3. The
stitching serves to unite the two ends in a very strong and durable manner. The
scarfing is preferably effected in such a manner that, when folded, the combined
thickness of the scarfed ends of the belting will equal approximately the average
thickness of the belting throughout its length.
This mode of joining the ends is very advantageous as one end of the joint is
completely covered and thus protected, and the end which is not covered is
turned or folded over at the edges of the belt. There is, therefore, much less
liability to wear or injury at the joint than is the case with the ordinary joints
of belting, only one end of the joint being exposed instead of both ends as
heretofore. Moreover the corners or points g of the said ends are brought to
the centre of the belt and are thus protected from displacement or detachment.
I sometimes take raw hide or other leather of slightly more than twice the width
of the belting to be made therefrom, so that, when the edges thereof are folded
over, they will more or less overlap one another; in this case the edges are
preferably bevelled as at c' and united by means of cement, as shown in Figure 7;
or they may be united in any other convenient manner, for example, by stitching
and cementing, as shown in Figure 8.
According to another modification of my invention, I make belting of greater
thickness, as shown in Figure 4, by inserting one or more additional strips or plies
of raw hide or other leather or other suitable material between the middle portion
of the piece or strip a of raw hide or leather and the parts thereof which are folded
over upon the same. Or 1 can use two or more thicknesses or plies of raw hide or
other leather of greater width than the belting to be made therefrom, and then
fold over the edges of all of the said plies.

page_text: It is advantageous to stitch the plies together along the edges or near the edges
of the belting as shown.
In the modification of my said invention illustrated in Figures 9 and 10, the
strip a is folded on itself so that the edges thereof only extend iuwardly a short
distance from the edges of the belt, and the belt is completed by the addition of a
separate band or strip secured to the strip a and abutting or nearly abutting
against the edges c2 cn each sile, the strips a and being united by rows of
stitching d, cement or other suitable means.
In Figures 11 and 12 I have shown further modifications in which the edges
of the strips a and h are scarfed together, and are further secured by stitching.
Figure 13 shows a still further modification of the belt shown in Figures 9
and 10, in which the strip his omitted; or, if desired, a separate or independent
belt of less width (shown in dotted lines) is arranged to run in the space between
the edges e, on the top or outside of the strip a. This separate belt may, if
desired, be made by folding over the edges of a strip of raw hide or other leather
as herein before described.
I sometimes combine three or more belts thus made, as shown for example in
Figure 14, the said belts being either placed together without being united, or
being united by stitching or otherwise, as may be desired.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. Raw hide or other leather belting composed of a strip or strips of such
material of greater width than the belting, folded over at both edges so that
the folds will be presented to the action of the belt-shifter, the plies being
cemented, stitched or otherwise secured to each other, substantially as hereinbefore
described.
Second. The jointing of leather belting by first scarfing the ends of a strip or
strips of the material of gréater width than the belting, and then folding over both
edges thereof so that one end of the joint is enclosed and the corners or points of
the strip at the other end are situated at the middle of the inner surface of the
belt, substantially as hereinbefore described.
Third. A raw hide or other leather belt composed of a strip or strips of the
material of greater width than the belting, jointed by the scarfing of the ends and
folded over at both edges, the plies being cemented, stitched or otherwise secured
together, substantially as herein before described.
Fourth. The improved raw hide or other leather belting made substantially as
described with reference to either of the forms or modifications shown in the
accompanying drawing, for the purposes above specified.
