RESERV
I, FRANCIS FLEMING of West Grove Mills, Halifax, in the County of York, Card
and Driving belt Manufacturer do hereby declare the nature of this invention to be
as follows:-
--
This invention relates to improvements in driving belts, or belts for transmitting
power and the object is to prevent lodgement of or to displace the air between the
biting or driving surface of the belt, and the surface of the pulley on which the belt
runs, the air cells or air cushions between the surface of belt and pulley being the
main cause of slipping" with the consequent loss of power.
According to this my invention I perforate the belt if of leather by punching, or
otherwise forming holes transversley or across the width of the belt, and thereby
providing escape ways for air trapped or lodging between the belt and the surface of
the pulley, the said holes do not detract practically from the tensile breaking strain
of the belt, and they also serve as lace holes for joining the ends of the belt.
In case of wovon belts the perforations or air passage ways will be formed in the
weaving or otherwise, whilst in leather hide, gutta percha, india rubber, dermatine, or
other material, punching or otherwise forming the perforations as may be found most
convenient.

page_text: Improvements in Belting for Transmitting Power.
I FRANCIS FLEMING of West Grove Mills, Halifax in the County of York, Card
and driving belt manufacturer, 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:-
This invention relates to improvements in driving belts, or belis for transmitting
power, and the object is to prevent lodgement of, or to displace the air between thic
belting, or driving surface of the belt, and the surface of the pulley on which the belt
runs, the air cells, or air cushions between the surface of the belt, and pulley being
the main cause of "slipping" with the consequent loss of power.
According to this my invention I perforate the belt, if of leather, by punching or
otherwise forming holes transversley, or across the belt, and thereby providing escape
ways for air trapped or lodged, between the belt, and the surface of the pulley, the
said holes do not detract practically from the tensile breaking strain of the belt, and
they also serve as lace holes for joining the ends of the belt.
In case of woven belts the perforations, or air passage ways will be formed in the
weaving, or otherwise, whilst in leather, hide, gutta-percha, india rubber, dermatine,
or other like material, punching, or otherwise forming the perforations as may be
found most convenient.
Such being the nature, and object of the said invention, the following is a completo
description of same, reference being had to the accompanying drawings forming a
part of this specification in which :-
Fig. 1. is a plan view of a portion of my improved belt.
Fig. 2. is a sectional elevation through line A, B of Fig. 1.
According to this my invention I perforate the belt 1 if of leather by punching, or
otherwise forming holes 2 transversley or through the belt 1. and thereby providing
escape ways for air trapped, or lodged between the belt 1 and the surface of the
pulley. The said holes 2 do not detract practically from the tensile strength of the
belt, and they also serve as lace holes for joining the ends of the belt.
In case of woven belts the perforations, or air passage ways 2 will be formed in
the weaving, but in case of leather and similar materials the holes are punched or
otherwise cut out, as may be most convenient.
Having now particularly described, and ascertained the nature, and object of my
said invention, and in what manner the same is to be employed 1 declare that what
I claim is :-
Driving belts, perforated for purpose, and as herein fully described and as illustrated
by the accompanying drawings.
