RESE
Improvements in Bands or Chains for the Transmission of Work.
I ALFRED JOHN GASKING of Lime Villa Essex Road Enfield in the County of
Middlesex Managing Director do hereby declare the nature of my said invention to be
as follows:
This invention has for its object improvements in bands or chains for the transmission
of work and which combines adhesive qualities with tensile and torsional strength
while at the same time considerable flexibility is retained and the band may be used
with equal facility on either side thereof thus enabling both faces to be used at the
same time-if desired-in driving from the same band without detriment thereto.
In some respects these bands are similar in construction to those described in the
Specification of my Patent No. 3942 of 20th March 1886 i.e. I use metal links and pins
with small sections of leather or other suitable material connected therewith but in the
former case the tension was in many cases taken wholly by the metal links only a
portion of the total length being assisted by the tensile strength of the leather (or
other material) itself, whereas according to my present invention I thread the pieces of
leather or other material to either lap each other alternately in each piece or thickness
of leather or in blocks or groups of say two or more thicknesses and probably in
medium width bands two thicknesses would be correct except at the outer edges where
two single ones may be used or two single ones crossing each other at the centre of
their length. By this means I obtain the strength of the leather itself in tension as
well as of the metal lengths each assisting and supporting the other. Besides this the
general and regular elasticity is more equal and the strain is less severe upon the cross
pins when the band is twisted indeed it approaches nearer to a solid leather band
without its disadvantages and with many advantages.
In some cases I make the holes in the metal links oblong or larger than the pin and
in making the band at first I couple the parts together with the pins as near together
as possible the leather sections having round holes and agreeing with the shortest pitch

page_text: of holes in links thus allowing in the first place all the strain to come direct upon the
leather sections themselves until the band is thoroughly stretched when the metal links
would take up and bear their part of the strain thus reducing the strain upon the
leather sections and dividing it with them. I make these sections of leather or other
material of any length shape or size and couple them up together in any way most
suitable for various purposes as described in the Specification of my Patent No 3942
of March 20th 1886. The metal links may be made any shape most suitable for
various purposes but sometimes I form them with a projection which is pierced with
one or more holes in order to attach appliances to one side of the belt for such
purposes as elevating or moving various substances and other similar objects.

Improvements in Bands or Chains for the Transmission of Work.
I ALFRED JOHN GASKING of Lime Villa Essex Road Enfield in the County of
Middlesex Managing Director do hereby declare the nature of my said 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 has for object improvements in bands or chains for the transmission
of work and which combines adhesive qualities with tensile and torsional strength
while at the same time considerable flexibility is retained and the band may be used
with equal facility or either side thereof thus enabling both faces to be used at the
same time if desired-in driving from the same band without detriment thereto.
In some respects these bands are similar in construction to those described in the
Specification of my Patent No. 3942 of 20th March 1886 i.e. I use metal links and pins
with small sections of leather or other suitable material connected therewith but in the
former case the tension was in many cases taken wholly by the inetal links only a
portion of the total length, being 'assisted by the tensile strength of the leather (or
other material) itself whereas according to my present invention I thread the pieces of
leather or other material to either lap each other alternately in each piece or thickness
of leather or in blocks or groups of say two or more thicknesses and probably in
medium width bands two thicknesses would be correct except at the outer edges where
two single ones may be used or two single ones crossing each other at the centre of
their length. By this means I obtain the strength of the leather itself in tension as
well as of the metal links each assisting and supporting the other. Besides this the
general and regular elasticity is more equal and the strain is less severe upon the cross
pins when the band is twisted indeed it approaches nearer to a solid leather band
without its disadvantages and with many advantages.
In some cases I make the holes in the metal links oblong or larger than the pin and
in making the band at first I couple the parts together with the pins as near together
as possible the leather sections having round holes and agreeing with the shortest
pitch of holes in links thus allowing in the first place all the strain to come direct upon
the leather sections themselves until the band is thoroughly stretched when the metal
links would take up and bear their part of the strain thus reducing the strain upon the
leather sections and dividing it with them.
I make these sections of leather or other material of any length shape or size--and
couple them up together in any way most suitable for various purposes as described in
The metal links may
the Specification of my Patent No. 3942 of March 20th 1886.
be made any shape most suitable for various purposes but sometimes I form them with
a projection which is pierced with one or more holes in order to attach appliances to
one side of the belt for such purposes as clevating or moving various substances and
other similar objects.
In order that my invention may be thoroughly understood I have appended
hereunto two sheets of drawings upon which several modifications are shown which
will serve to illustrate the principle.

page_text: Figure 1 is a plan showing a very strong band made up of the leather sections A which
are made of two thicknesses_except at the outer edges which are generally one
thickness and the metal links B and the pins C and washers D.
Figure 2 is a side elevation of the edge of the belt showing the washers D and
pins C.
Figure 3 is a similar elevation to Figure 2 but showing that edge of the belt which
receives the heads C of the pins C.
Figure 4 is a horizontal sectional elevation through two pins C for the purpose of
showing that the pins are so left in the leather pieces A as to allow them to slightly
stretch or bed themselves before taking a bearing upon the side of the holes of the
links B i.c. the metal links are slightly longer in pitch than the leather pieces A or the
holes in B may be made oval horizontally or the holes may be slightly larger in
diameter which allows the necessary stretch as set forth. Small spaces and 2 are
marked in the metal links which allow for stretch.
Figures 5 and 6 are plan and edge elevation of a modification showing three
thicknesses of leather groups A crossing each other lengthwise and with three rows of
metal links B but otherwise tightened up to allow of the leather stretching as
previously explained for Figure 4.
Figures 7 and 8 are plan and edge elevation of a band with four leathers A grouped
together in three single rows and four rows of metal links B but otherwise the
construction is practically the same.
Figures 9, 10 and 11 show metal links of a special kind which may be used at
intervals in the construction of these bands to receive elevators at the holes E
and other attachments used upon bands. Of course the shapes may be varied to suit
circumstances.
It will be noticed in all cases that both the leather sections A and the links B
must be broken before the band can be severed the tension being divided between
the two.
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 :-
First: The improved belt for transmitting power consisting of a chain work of
metallic links and transverse rods in combination with leather or other flexible sections
or pieces which are also linked the one to the other by the said pins substantially as
herein set forth.
Second-In compound belts for transmitting power the formation of an arm or extra
hole to the metallic links for the purpose of connecting other parts at intervals thereto
substantially as set forth.
