PROVISIONAL SPECIFICATION.
Improvements in Belts or Bands for Driving Machinery and for
like Uses.
We JAMES WETHERILT of 179 Maida Vale, in the County of Middlesex,
Gentleman and WILLIAM JOSEPH ARMITAGE of 81 Bramley Road, Notting
Hill, in the same county, Bicycle and Perambulator Manufacturer do hereby
declare the nature of this invention to be as follows:-
Our invention relates to the manufacture of belts or bands of an improved
construction for use in driving machinery, or parts of machinery and for like uses.
In carrying out our invention we employ metal strips, preferably steel of a
suitable quality placed side by side and crosswise are placed other like strips.
Each strip of metal has formed, as by punching at regulated distances apart, holes
therethrough and the holes in the underlying and overlying strips are arranged to
coincide accurately; and therethrough are forced blocks of india rubber, or
analogous composition, sufficiently to leave a portion of each block, on each side
the superimposed perforated strips, projecting.
Round, square or other shaped rubber blocks may be employed.
The holes in the bands or strips may correspond to the shapes of the blocks,
and be arranged so that when the strips are in their correct position in the driving
band for use the blocks shall be securely held.
Round or oval holes may be employed for use with square plugs, or other
combinations of forms of the respective parts may be employed.
The driving belts may be formed of longitudinal bands or strips, in some cases
of the entire length of the belt, the opposite ends being connected by overlay
jointing, steel, copper, brass or other suitable eyelet plates, or jointing parts being
used to connect the ends at the coincident perforations in the respective strips.
Such a construction of belting is not limited practically as to length, breadth
and strength.
Belts of the improved construction will be found not liable to stretch, to be very
durable, to possess great frictional hold, to be easily repaired, or altered in length
or additions made thereto.
The joints made being by means of the perforations at the previously adjusted
distances, they can hardly be out of the square.
Air between the pullies and the improved driving belts cannot lodge and cannot
therefore interfere with the grip of the belts on the pullies.
The joints made as described will not cause "jumping" or interfere with the
smooth running of the belts.
By these means undesirable thickening of the belt or band at the locality of a
joint is avoided.

Improvements in Belts or Bands for Driving Machinery and for
like Uses.
We JAMES WETHERILT, of 179 Maida Vale, in the County of Middlesex,.
Gentleman, and WILLIAM JOSEPH ARMITAGE of 81 Bramley Road, Notting
Hill, in the same county, Bicycle and Perambulator 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 :-
Our invention relates to the manufacture of belts or bands of an improved
construction for use in the transmission of power such as driving machinery, or
parts of machinery and for like uses.
Our invention embodies a band for the transmission of power composed of a
metal strip or strips preferably steel of a suitable quality placed side by side and
crosswise are placed other like strips. Each strip of metal has formed, as by
punching at regulated distances apart, holes therethrough and the holes in the
underlying and overlying strips are arranged to coincide accurately; and there-
through are forced blocks of india rubber, or analogous composition, sufficiently to
leave a portion of each block, on each side the superimposed perforated strips
projecting, metal eyelet connections being used at the meeting ends of the band.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan view of a portion of our improved construction of belt, and
Fig. 2 an edge view of the same.
The right hand half of these figures shows one way in which the cross strips
may be applied and the left hand half shows a modification.
Fig. 3 is an edge view, partly in section, drawn to a larger scale.
Fig. 4 is a sectional side view and
Fig. 5 a sectional plan view of a detail showing the jointing of the opposite
ends of a driving belt.
Fig. 6 shows a detail.
Fig. 7 shows a face view of the improved belt consisting of one wide strip of
metal.
Fig. 8 shows an edge view of the strip as sometimes formed by two or more
layers.
Fig. 9 shows a plan view partly in section of a metal strip according to a
modification.
Fig. 10 shows the same by an edge view.
a, a are longitudinal metal strips, b, bare cross strips, c, c rubber blocks,
d, d perforations for the same, and e is a metal eyelet connection.
Although in the drawings we have shown the india rubber block in shape round,
er square, other shaped rubber blocks may be employed in lieu thereof.
The holes e in the bands or strips may correspond to the shapes of the blocks,
and be arranged so that when the strips are in their correct position in the driving
band for use the blocks shall be securely held.
Round or oval holes may be employed for use with square plugs, as shown in
Figs. 9 and 10 or other combinations of forms of the respective parts may be
employed.
The driving belts may be formed of longitudinal bands a or strips, in some cases
of the entire length of the belt, the opposite ends being connected by overlay

page_text: jointing, steel, copper, brass or other suitable eyelet plates e, or jointing parts
being used to connect the ends at the coincident perforations in the respective
strips, see Figs. 4 and 5.
Fig. 6 shows one of these eyelet plates e before insertion.
Suitable pressure clinches the plate or ring to the form shown in Fig. 4.
Such a construction of belting is not limited practically as to length, breadth
and strength.
Belts of the improved construction will be found not liable to stretch, to be very
durable, to possess great frictional hold, to be easily repaired, or altered in length
or additions made thereto.
The joints made being by means of the perforations at the previously adjusted
distances, they can hardly be out of the square.
The longitudinal band or bands may be built up of several laminæ of metal
instead of one thicker strip, see Fig. 8.
Air between the pulleys and the improved driving belts cannot lodge and cannot
therefore interfere with the grip of the belts on the pullies.
The joints made as described will not cause "jumping" or interfere with the
smooth running of the belts.
By these means undesirable thickening of the belt or band at the locality of a
joint is avoided.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. A band for the transmission of power consisting of a continuous metal strip
of suitable width and length perforated at adjusted distances with series of holes
in combination with recessed plugs of elastic material as rubber held in said holes
and means for connecting the ends of said band, substantially as set forth.
2. In a band for the transmission of power, longitudinal metal strips laid side
by side and perforated with series of holes, other metal strips laid crosswise
thereof perforated with series of holes corresponding to those in the longitudinal
bands in combination with recessed plugs of elastic material as rubber and means
for connecting the ends of the band, substantially as set forth.
3. In a band for the transmission of power, longitudinal metal strips laid side
by side and perforated at regular distances throughout the band, overlying parallel
cross strips having perforations corresponding to those in the underlying longitudinal
strips and coinciding accurately therewith in combination therewith blocks of india
rubber fixed in said perforations and metal eyelet connections at the meeting ends
of the bands, substantially as set forth.
