IMPROVEMENTS IN THE MANUFACTURE OF DRIVING BELTS
Year: 1885

page_text: I JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents, do hereby declare the nature of my invention for
"IMPROVEMENTS IN THE MANUFACTURE OF DRIVING BELTS" to be as follows:-
The invention consists in the employment of asbestos in the manufacture of
driving belts whereby I obtain a belt capable of resisting high temperatures, acids
or moisture, which will stretch very little and whose smooth surface ensures a good
adherence.
I employ asbestos cloth for the manufacture of the belts. The cloth which is
folded into a number of plies or folds proportionate to the required resistance to be
obtained is cemented together by caoutchouc. The cloth is stretched before and
during the process of vulcanization, and during this operation the belt is strongly
compressed. The cloth may be made entirely of asbestos, or either the warp or the
weft may be made of other material such as silk, cotton &c. In lieu of the
caoutchouc which binds or cements the parts of the belt together I may use any
other suitable material, coating or process, and the asbestos may, if desired, be in
the form of threads instead of cloth. The caoutchouc or the material used in lieu
thereof may, if thought desirable, form a greater or less thickness on the exterior of
the belt, or not be apparent, and any suitable vegetable, metallic or other substance
may be placed in the interior of the belt. The section of the belt may be
rectangular, circular or otherwise, and the ends may be joined in any ordinary
manner.

I JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents do hereby declare the nature of my invention for
"IMPROVEMENTS IN THE MANUFACTURE OF DRIVING BELTS (a communication
from abroad by Jérôme André Magnin of 1 Boulevard St Denis, Paris, France,
Driving Belt Manufacturer) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
The invention consists in the employment of asbestos in the manufacture of
driving belts whereby I obtain a belt capable of resisting high temperatures, acids,
or moisture. It will stretch very little and its smooth surface ensures a good
adherence.
The asbestos may be employed in different ways for the manufacture of the
belts. One way is to use it in the form of cloth. The cloth which is folded into
a number of plies or folds proportionate to the required resistance to be obtained is
cemented together by caoutchouc. The cloth is stretched before and during the
process of vulcanization, and during this operation the belt is strongly compressed.
The cloth may be made entirely of asbestos, or either the warp or the weft may be
made of other material such as silk, cotton, &. In lieu of the caoutchouc which
binds or cements the parts of the belt together I may use any other suitable
material, coating or process, and the asbestos may, if desired, be in the form of
threads instead of cloth. The caoutchouc or the material used in lieu thereof may
if thought desirable form a greater or less thickness on the exterior of the belt, or
not be apparent, and any suitable vegetable, metallic or other substance may be
placed in the interior of the belt. Or, the asbestos may be used in the form of
paint or solution to paint, coat or impregnate belts made of cotton, hemp, leather
or other material.
•
The section of the belt may be rectangular, circular or otherwise and the ends
may be joined in any ordinary manner.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, as communicated to
me, I declare that what I claim is
The employment of asbestos in the manufacture of driving belts substantially as
hereinbefore described.
