Improvements in Driving Chains.
JAMES MILLS of No. 8 Harders Road, Queen's Road, Peckham, London, S.E.
Printer, do hereby declare the nature of this invention to be as follows:-
My invention relates to a new and improved device for cycle chains, and chains of
other vehicles. The object of my said invention is to provide a detachable and
interchangeable chain link.
My chain for cycles and other vehicles consists of detachable links, which for the
purpose of my invention can be shaped or designed in either of the following
forms: the link can be in the form of a hook (which can be either a single or double
hook) having a bar passing through the top or upper end. In connecting this
detachable link the bar of the one is drawn through the hook or hooks of the other.
To disconnect the links, the bar referred to, is drawn backwards from the hook or
hooks of the other.
For the above described chain, the cycle chain wheel must be suitably adapted.
Or, for the purpose of my invention I provide a link which in shape resembles
the ordinary chain link now in use, but is made detachable and interchangeable,
having a hook attachment provided, which chain is adapted for chain wheels
now in use.
The attachment provided to this link, above referred to, is simply a hook
coupling at the front end of link which slips over the bush or bar at rear end
of link, in place of the ordinary coupling now in use.
Dated the 10th day of August 1896.
I, JAMES MILLS of No. 8 Harders Road Queen's Road Peckham London S.E.
Printer 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:-
My invention relates to a new and improved device for bycicle trycicle chains and all
and every other known vehicle propelled by such agency or machinery stationary or
otherwise.
The purpose then of my said invention is in providing a detachable and
interchangeable chain link which is of such a character that in the event of any
portion of the detachable or interchangeable chain link breaking by any extra strain
or unlooked for accident it can be readily mended and in a very short space of time
by having in readiness one or more of the chain links in the tool pouch of any bycicle
[Price 8d1

page_text: trycicle or like machine propelled by such agency as hereinafter described. This
chain then for bycicles tricycles or any class of machinery propelled by such like
agency consists then in being detachable or interchangeable links which for the
purpose of my invention can be shaped or designed in either of the following forins
as shewn on the drawings in Figs. 1, 2, 3, 4 accompanying this specification such as
the links being in the form of a hook which can be either single or double hook
having a bar passing through the top or upper end.
In connecting this detachable or interchangeable chain link the bar of the one is
drawn through the hook or hooks of the other and in disconnecting the links the bar
referred to is drawn backwards from the hook or hooks of the other so that if it is
desired to clean the chain thoroughly at any time it can be readily parted cleaned and
reinstated or put together in a very short space of time this then fully described
driving chain as shewn in Figs. 1, 2, 3, 4. Figs. 2 and 3 will engage with any wheel
or wheels of bycicle tricycle or other machinery suitably adapted or so constructed
the hook chain may fall into a groove the periphery or outer edges of the wheel which
will have the receptacles or cogs for each end of the bars to fall into or engage with
as shewn in Figs. 2 and 3.
Or for the further purpose of my invention I provide a link which in shape
resembles the ordinary chain link now in use but is made detachable and
interchangeable by having a hook attachment provided which chain is applicable for
chain wheels now in general use as shewn in Figs. 1 and 4.
The attachment therefore provided to this link as before mentioned is simply a
hook coupling at the front end of link which slips over the bush or bar at rear end of
link in place of the ordinary coupling now in use.
Fig. 5 is a side view of my driving and propelling chain as shewn in Fig. 1.
In the before mentioned and detachable and interchangeable links forming my
driving chain complete I reserve the right to make or manufacture the driving chain
in its entirety in any class of metal iron or steel most essential or desirable for
durability wear and service for propelling any bycicle trycicle vehicle or machinery
stationary or otherwise as before mentioned.
My driving chain is also applicable to either shortning or lengthning as necessity
may require for gearing purposes.
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. In a driving chain adapted for use in propelling bycicles trycicles vehicles
or other machinery provided with detachable and interchangeable links in the
form of a hook having a bar passing through the top or upper end for the
purpose of connecting, disconnecting, propelling, cleaning or repairing as may
be required as herein before described.
2. In a drawing chain adapted for use in propelling bycicles trycicles vehicles
or other machinery provided with detachable or interchangeable link or links
forming hook at front end of such link or links for the purpose of being readily
removed from one another forming such driving chain as herein before described.
3. In a driving chain adapted for use in propelling bycicles trycicles vehicles
or other machinery provided with ordinary book attachment applicable for chain
wheels now in use as herein before described.
4. In a driving chain adapted for use in propelling bycicles trycicles vehicles
or other machinery provided with hook couplings at front end for purpose of slipping
over bush or bar at rear end of such links as herein before described.
Dated this Eighth day of May 1897.
