Complete Specification Left, 17th Sept., 1894-Accepted, 3rd Nov., 1894
PROVISIONAL SPECIFICATION.
An Improved Detachable Driving Chain for Machinery or Cycles.
I, ARCHIBALD LEE GOODALL of The Plough Inn, Derby in the County
of Derby, Licensed Victualler, do hereby declare the nature of this invention to be
as follows:-
My invention relates to an improved construction of a detachable driving chain
for machinery or cycles, and in carrying out my said invention I construct my
improved detachable driving chain with side links, the holes or perforations in
which are formed to fit accurately over heads on pins which are united by a cross
central portion. Each of these central portions carries four heads, two on each
side of the chain.
In putting the chain together the open parts of the side links are passed
over the heads of the central portions and then turned at right angles thereto and
bear upon the pins and work between the heads and the cross central pieces.
Openings are thus left between the side links and between the central portions, in
which the sprockets of the sprocket wheel fit when in work.
Dated this 5th day of October 1894.

COMPLETE SPECIFICATION.
An Improved Detachable Driving Chain for Machinery or Cycles.
I, ARCHIBALD LEE GOODALL of The Plough Inn, Loudon Road, Derby
in the County of Derby, Licensed Victualler, 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 an improved construction of a detachable driving chain
for machinery or cycles and in describing the same I shall refer to the accompanying
sheet of drawings, the different figures and letters of reference upon which will be
deemed to form a part of this Specification.
Figure 1 shews a plan of one of the central portions of the said chain, detached
from the side links.
Figure 2 is a side elevation of the above.
Figure 3 is a side elevation shewing the construction of the chain when put
together.
Figure 4 is a plan of the parts shewn on Figure 3.
In carrying out my invention I construct my improved detachable driving chain
with side links A A¹, the holes or perforations B in which are formed to fit
accurately over the heads C on the pins D which are united by a cross portion E.
It will be seen that each of these central portions carries four heads C, the two
heads on one side of the chain being turned in one direction, that is to say with the
full ends either upwards or downwards and the narrow ends either downwards or
upwards; while the heads belonging to that particular central portion on the other
side of the chain are turned in the opposite direction, (as will be seen upon referring
to the drawings and particularly to Figures 1 and 2); the object of this being to
make it impossible for the links to slip off the central portion when the chain
is completed and in work. In putting the chain together the open parts of the side

page_text: links are passed over the heads C of the central portions and then turned at right
angles thereto and bear upon the pins D and work between the heads C and cross
pieces E. It will be seen that openings F are left between the side links and
between the central portions, in which the sprockets of the sprocket wheel fit when
in work.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what. I
claim is :-
The improved construction of detachable driving chains having side links such
as A, A¹, and central portions consisting of cross pieces E, pins D and heads C
substantially as and for the purposes described and illustrated.
