Complete Specification Left, 1st Mar., 1900-Accepted, 7th Apr., 1900
I, JAMES WETHERILT, of 179, Maida Vale, in the County of Middlesex, Gen-
tleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in belts or bands for use in the trans-
mission of power for driving machinery or like use.
The improved band or belt is formed as a continuous strip or band of sheet
steel, or other suitable metallic substance leather, cotton, or combination of fibrous
material and wire, or other suitable material joined as required to form a suffi-
ciently long and continuous band.
In the expression continuous strip or band I include constructions made up
of any number of pieces joined together, or connected.
Upon the frictional surface of this band I affix circular or other suitably shaped
discs, or other forms of india rubber, or equivalent elastic material, fastening
these frictional surfaces, in series, to the band, by means of rivets
fastenings
or other
A convenient form of belt, according to my invention, consists of a band of
thin sheet steel of suitable quality and temper joined at its ends, as by eyelets,
and having thin discs of vulcanized india rubber arranged in rows transversely
and longitudinally, each disc being secured to the band by a bifurcated rivet,
whose head is on the outer side of the band and the rivet stems pass through the
steel and the india rubber and are then clinched on the side to be engaged on the
pulley or wheel, the clinching lying bedded in the rubber, or the reverse arrange-
ment may be adopted.
The form of the separate pieces of the elastic material may be varied to the
eircumstances of the case-such forms as strips may be applied lengthwise, across
diagonally, or in other relations or arrangements.
By the use of this invention slack belting can be used, and stretching of the
belt or band is rendered harmless.
The jointing of the belts and bands is much facilitated and greatly improved,
whilst an efficient means for the transmission of power at a low cost is secured.
not attended with any danger of failure of operation by reason of the lodgment
of air between the band and the surface it is placed in frictional contact with,
thereby avoiding "air cushioning" and its consequent waste of power-efficient
grip being constantly maintained.

page_text: I, JAMES WETHERILT, of 179, Maida Vale, in the County of Middlesex, Gen-
tleman, 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 belts or bands for use in the trans-
mission of power for driving machinery or like use.
The improved band, or belt, is formed as a continuous strip or strips, or band,
or bands of sheet steel, or other suitable metallic substance, leather, cotton, or
combination of fibrous material and wire, or other suitable material, joined as
required to form a sufficiently long and continuous band.
In the expression continuous strip, or band, I include constructions made up
of any number of pieces joined together, or connected.
Upon the frictional surface of this band I affix circular, or other suitably shaped
discs, or other forms of india rubber, or equivalent elastic material, fastening
these frictional surfaces, in series, to the band, by means of rivets, or other
fastenings.
Figure 1 shows by an external, or plan view an arrangement of pieces of
steel connected together and faced on the under working side by strips of vul-
canized india rubber of oblong forms ranged side by side.
Fig. 2 is an edge view of the piece of belting shown by Fig. 1.
Fig. 3 is an under side view of the same.
Fig. 4 is a cross section of Fig. 1 about the line A, A.
Fig. 5 shows by a side view to much reduced scale a driving band of the kind
to be described working over two pullies.
Fig. 6, shows a similar view to Fig. 1, of a portion of a belt according to this
invention, but with india rubber pieces of circular form instead of oblong as
in the previous figures.
Fig. 7 is an edge view, Fig. 8 an underside view and Fig. 9, a cross section
of the arrangement indicated by Fig. 6.
A convenient form of belt, according to my invention, consists of a band of
thin sheet steel a of suitable quality and temper joined at its ends a¹ as by
eyelets and having thin pieces of vulcanized india rubber bb of oblong form
arranged in rows transversely as in Figs. 1 to 4, or it may be longitudinally,
each piece being secured to the band by a bifurcated rivet e whose head dis
on the outer side of the band, and the rivet stems pass through the steel and
the india rubber and are then clinched on the side to be engaged on the pulley or
wheel as d, d, Fig. 5, the clinching lying bedded in the rubber b, b, or the
reverse arrangement may be adopted. Or, as in Figs. 6 to 9, the rubber may
take the form of series of discs b, b, arranged in rows transversely and longi-
tudinally of the band a.
In place of a single rivet, a plurality of rivets may be employed or instead
other suitable forms of fastenings may be substituted.
The form of the separate pieces of the elastic material b, b, may be varied to
suit the circumstances of the particular use, or case-such forms as strips may
be applied lengthwise across diagonally, or in other relations or combinations of
arrangements thereof.
By the use of this invention slack belting can be used if desired and stretching
of the belt, or band if it should occur is rendered harmless.
The jointing of belts and bands is much facilitated and greatly improved,

page_text: whilst an efficient means for the transmission of power at a low cost is secured,
not attended with any danger of failure of operation by reason of the lodge-
ment of air between the band and the surface it is placed in frictional contact
with, thereby avoiding "air cushioning" and its consequent waste of power-
efficient grip being constantly maintained.
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:
In a belt or band for the transmission of power the combination of a thin
steel band, or equivalent band, or combination of materials either composed of
one piece, or a number of pieces, joined at its or their ends by eyelets, or equi-
valent fastenings and having secured thereto on the working or frictional side
thereof pieces of india rubber or equivalent elastic material, all substantially as
set forth and illustrated by the accompanying drawings.
