Improvements in and relating to Driving Bands for Cycles, Vehicles,
or other Light Machinery.
BELTON TATTNALL HAMILTON 1 Myrtle Terrace Crayford, in the County of
Kent, do hereby declare the nature of this invention to be as follows:-
My invention relates to driving bands for the transmission of circular motion
between any two or more rotating spindles or shafts and may be applied preferably
to cycles or other light machinery.
My invention relates to the use of a metal ribbon or strip preferably steel forming
an endless band upon which are fixed at suitable distances apart, as I shall herein-
after describe, lugs, which project out and beyond on either side of the ribbon and
are so shaped and arranged to engage with notches or teeth cut in or on the wheels
on which the said ribbon sun
In the accompanying drawings:-
Fig. 1. shows a side elevation of a short length of the said band.
Fig. 2. shows a plan of the same.
Figs. 3, 4, 5, 6 & 7 show the method of fixing the lugs on to the ribbon.
Fig. 8. shows a side elevation of wheel on which band runs.
Fig. 9. shows a section of same wheel.
My invention relates to the manner or method of fixing these lugs on to the
ribbon. The lugs are formed of two pieces, the upper half (b) and the lower
half (6) one piece having a slot cut longitudinally through it and the other piece
having a corresponding ridge projecting on it which shall fit into the slot on the
former piece. This ridge or slot might preferably be cut so that its direction shall
lie across or at right-angles to the metal ribbon on which they are to be fixed.
These lugs are now pressed on to the ribbon one piece from above and the other
from below on to the two flat sides of the ribbon so as to clip the said ribbon
between them at the same time making a corrugation in the ribbon in such a way
that the lugs are fixed immoveably on the ribbon without in any way reducing its
sectional area, the ends of the lugs projecting out beyond the ribbon on either
side (Figs. 3, 4, 5 & 6).
Over these projecting ends are now placed hardened steel collars one on either
side of the ribbon & the ends of the lugs rivetted over in such a way so as to keep
the said collars in position and also to keep the lugs in position on the ribbon
(Fig. 7).
The wheels on which the ribbon runs, one the driver the other the driven should
be formed with a channel or L-shaped section rims the ribbon running between
the two flanges and bearing on the flat bed of the chaunel; the projecting sides or
flanges of the channels should be cut into notches or teeth of a suitable shape so as
to engage with the projecting ends of the lugs on the ribbon (Figs. 8 & 9).
In the accompanying drawings:-
Fig. 1. shows a side elevation of a short length of the said band.
Fig. 2. shows a plan of the same.
Figs. 3, 4, 5, 6 & 7 show the method of fixing the lugs on to the ribbon.
Fig. 8. shows a side elevation of wheel on which band runs.
Fig. 9. shows a section of same wheel.
My invention relates to the manner or method of fixing these lugs on to the
ribbon. The lugs are formed of two pieces, the upper half (b) and the lower
half (6) one piece having a slot cut longitudinally through it and the other piece
having a corresponding ridge projecting on it which shall fit into the slot on the
former piece. This ridge or slot might preferably be cut so that its direction shall
lie across or at right-angles to the metal ribbon on which they are to be fixed.
These lugs are now pressed on to the ribbon one piece from above and the other
from below on to the two flat sides of the ribbon so as to clip the said ribbon
between them at the same time making a corrugation in the ribbon in such a way
that the lugs are fixed immoveably on the ribbon without in any way reducing its
sectional area, the ends of the lugs projecting out beyond the ribbon on either
side (Figs. 3, 4, 5 & 6).
Over these projecting ends are now placed hardened steel collars one on either
side of the ribbon & the ends of the lugs rivetted over in such a way so as to keep
the said collars in position and also to keep the lugs in position on the ribbon
(Fig. 7).
The wheels on which the ribbon runs, one the driver the other the driven should
be formed with a channel or L-shaped section rims the ribbon running between
the two flanges and bearing on the flat bed of the chaunel; the projecting sides or
flanges of the channels should be cut into notches or teeth of a suitable shape so as
to engage with the projecting ends of the lugs on the ribbon (Figs. 8 & 9).

Improvements in and relating to Driving Bands for Cycles, Vehicles,
or other Light Machinery.
I, BELTON TATTNALL HAMILTON of 1, Myrtle Terrace, Crayford, in the
County of Kent, Mechanical Engineer, 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 driving bands for transmitting rotary motion, and it
consists in attaching to a band formed of one or more metallic strips or wires, a
series of transverse lugs arranged at any predetermined pitch.
In the drawing filed with the Provisional Specification and in the accompanying
drawing which illustrates this invention :-
Figure 1 is a view in side elevation of a short length of the band,
Figure 2 is a view in plan thereof.
Figures 3, 4, 5, 6 and 7 are views showing one method of attaching the lugs to
the band.
Figures 8 and 9 are broken views in side elevation and transverse section
respectively of a wheel suitable for use with this driving band.
Figure 10 is a broken view in plan showing an alternative construction.
Figures 11 and 12 are views showing an alternative method of attaching the lugs
to the band, and
Figures 13, 14, 15 and 16 are views showing a further modification.
Throughout the views similar parts are marked with like letters of reference.
The band a may consist either of a single strip as shown by Figures 1 and 2 or
of a series of strips-which may be either wires or flat ribbons-as shown by
Figure 10.
The lugs are formed in two pieces 6 and 61, so shaped that when placed together
with the thickness of the band between them they form round pins with reduced
ends. In the flat side of the one piece b is cut or formed a central longitudinal
slot and in the flat side of the other piece b' is a central longitudinal ridge adapted
to fit in the slot in the piece b.
The lugs are fixed to the band a by placing the pieces b and 6 one on each side
of it and subjecting them to pressure so that the ridge on the piece b' and the slot
I in the piece b form a corrugation in the band. Hardened steel collars c are then
placed over the reduced ends of the lugs which are then rivetted over in such a
way as to fix the said collars on to the lugs. It will be seen that by this con-
struction the lugs which form the driving media are securely fixed to the band
without in any way reducing its sectional area.
As a modification the lugs may each be made in one piece as shown by Figures 11
and 12. In this construction the lug B is slotted transversely and has a hole through
its centre to receive a pin d. The band runs over the pin d which is then rivetted
up at each end.
Figures 13, 14, 15 and 16 show another method of attaching the lugs to the
band. In this construction the lugs are each formed in two parts b and b' which
when placed together leave a circular hole running through them. After the
corrugations have been formed on the band the two parts of the lugs are placed
above and below them respectively and a pin d is passed through the hole and
rivetted up at each end. The two parts band 6' of the lugs interlock with each
other by means of dovetails or their equivalents as shown.
The wheels intended to transmit motion to or receive motion from the band
hereinbefore described have channelled rims the sides or flanges of which are

page_text: provided with suitably shaped recesses to receive the ends of the lugs on the band,
and the bottom of the channel has transverse grooves to receive the under parts of
the said lugs.
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 :-
(1.) The improvements in driving bands, substantially as hereinbefore described
and illustrated by the accompanying drawing.
(2.) A driving band consisting of one or more metallic strips or wires laid side
by side and having transverse corrugations formed at a predetermined pitch, and
of a series of lugs adapted to form the driving projections thereof formed and fixed
to the said strips or wires, as set forth.
