PROVISIONAL SPECIFICATION.
Improvements in Driving Chains for Use in Bicycles, Tricycles,
Velocipedes, Motor Cars, Carriages, Vehicles, and other such
Purposes.
ALBERT BAGSHAW, Bk. 86, Park Lane, Aston, Birmingham, Jeweller, & JOHN
TYLER BARNSLEY BENNETT, 2, Villa Road, Handsworth, Agent, do hereby declare the
nature of this invention to be as follows:-
The object of our improvements in driving chains, for use upon cycles & general
machines is to prevent the wearing away of the rivet, by taking the bearing
therefrom, of the roller or block or such like, & placing it upon a cone or spike
formed upon the side links.
In carrying out our improvements we form a side link,with two cones, or spikes
thereon, & with a hole through each cone. The cones are formed upon the inside of
the link.
Operation We take our improved side links, thus made (& having passed
through the process of manufacturing) with their inside cones formed thereon, we
place the roller's upon the cones & the rivets through the holes in the cones, & so
continue as ordinary to make any required chain. The roller's do not touch the rivets
but their edges revolve round the cones, thereby greatly reducing friction, & the
rivets freeded from bearing cannot wear away. It is understood, in carrying out our
improvements we shall adopt any mere modification required-We shall use other
links, with our improved links, for making a twin roller chain, or when using the
double block roller-We countersink such to fit our cones in the side link's or we
shall make a block roller in two halves.

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:-
The object of our improvements in driving chains for use upon cycles, & general
machines, for driving purposes is to prevent, the wearing away of the rivets, by
taking the bearing from off the roller, or block or such like, & placing it upon a cone

side link with two cones or spikes thereon & with a hole through each cone. The
cones are formed upon the inside of the link. We take our improved side link's
thus made & having passed through the process of manufacture, with their cones
formed thereon-We place the rollers upon the cones & the rivets through the holes
in the cones & so continue as ordinary to make any required chain. The rollers
do not touch the rivets, but their edges revolve round the the cone thereby greatly
reducing friction, & the rivets freed from bearing cannot wear away. It is
understood in carrying out our improvements we shall adopt, any mere modification
required, we shall use, other side links, if desired with our improved link's when
making a twin roller chain, or any other pattern chain, or when using the block
link, or the roller. We countersink such to fit, our side link's, or we shall make a
block link, or a roller in two halves, from sheet metal & if required strengthen such
with washer's inside. We stamp the impression of the countersink in the sheet
metal, block link, or roller, so as to fit, our coned link or the spike let into the
link.

In order that our improvements may be fully understood
particularly describe them, with the aid of the accompanying drawing's in which
similar parts are marked with like letter of reference.
Fig. 1. represents an elevation, of a side link, showing two raised cones thereon.
Fig. 2. represents an elevation, of a side link, showing two sunken cones therein.
Fig. 3. represents a side elevation, of two link's & showing one placed within the
other for working & bearing purposes.
Fig. 4. represents an elevation of the usual block link, countersunk, held in
position, by the coned links.
Fig. 5. represents an ordinary block link, in elevation, & countersunk.
Fig. 6. represents in plan two half blocks ready to be put together, to work upon
the coned link's.
Fig. 7. represents an elevation, of a single roller, being carried by the coned
link's.
Fig. 8. represents in plan, the single roller, countersunk, so as to fit, the coned
link's.
Fig. 9. represents in plan two half roller's ready to fit the coned link's when put
together.
Fig. 10. represents in elevation a section, of a chain, with the coned link's jointed
to other link's, & carrying single roller's, made from sheet metal stamped in two
halves or made in one piece.
a cone on link, b link, c block link, d single roller, e countersunk, sheet
metal, block link, or half of same, or represents the block link, stamped in one
piece g sheet metal roller-or half of same-or represents roller stamped in one piece,
h sheet metal, roller, in position, j back of sunken cone on link, b other side
links.
It is understood, that in constructing our sheet metal block, in one piece of
metal we cut from a suitable piece of metal, a round or any other shaped ordinary
flate blank of any required thickness or press or stamp the same between dies, or
tools, making indentations on each side, of the flat blank, which is somewhat like
countersinking, & piercing holes therein & is in appearance the same as the half
block link as shown in Figure 6 in the drawings, & in like manner
we construct rollers in one piece from flat blanks, which have the same appearance,
as shown in Figure 9. such block link's & rollers will fit, our cones upon the side
link's.
Having now particulary described & ascertained the nature of our
invention, & in what manner the same is to be performed, we declare that what
we claim is :-
1st Cones upon a side link, as described & set forth & illustrated in the
accompanying drawings.

page_text: 2nd A link, with cones formed thereon, for use in a chain, as set forth described
& illustrated in the accompanying drawings.
3rd To countersink the ordinary block link or single roller, to fit, our come link's
in a chain as set forth, described & illustrated in the accompanying drawings.
4th To make a block link, in two halves, from sheet metal, to fit our cones, as
set forth & described.
5th To make a roller, in two halves, from sheet metal, to fit our cones, as set
forth & described.
5th To make a block link, in one piece, from sheet metal, to fit, our cones as set
forth & described.
6th To make a roller, in one piece, from sheet metal, to fit our cones, as set forth
described.
