COMPLETE SPECIFICATION.
Improvements in Ohains for Driving Cycles, Motor-cars, and other
Machinery.
I, EDWIN TAYLOR, of 1 Alfred Street, Warstone Lane, Birmingham, in the
County of Warwick, Stamper and Piercer do hereby declare the nature of my
said 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 has for its object improvements in chaius for driving cycles, motor-.
cars and other machinery by which greater certainty is ensured in the chain.
passing over the teeth of the sprocket wheels, and the liability of fouling or riding
upon the teeth is avoided in a very simple and effective manner without reducing
the section of the metal or weakening the link-indeed the links of py improved
chain are stiffer than those now in use.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a sheet of drawings illustrating the-
same but it must be understood that the general formation of the parts of the chain
may be considerably varied to meet the various requirements of driving chains.
without departing from the principle of the invention.
Figure 1 is a side view of two links A, A of a driving chain connected by the
coupling block B.
Figure 2, is a plan of the two links A, A and of the coupling block B.
Figure 3 is a cross section through one of the links A on the line 1. 2.
Figure 4 is an elevation showing a modification of the link A to which my
invention is applied.
Figure 5 is a cross section of the link as seen at Figure 4 on the line 3. 4.
My invention has reference to the links A which couple the blocks B together
by means of the rivets E but the blocks B may be of any known kind. I form.
my new links A to any desired external configuration so far as the outline of their
edges are concerned, but I form each link in the case of such links as aro shewn at.
Figures 12 and 3 with the side which runs upon the sprocket wheels with a
recessed or cranked portion such as a' which has the effect of widening the sides.
of the links which are near to the sides of the sprocket wheel teeth so that they
are not liable to ride upon the teeth and at the same time this cranking has the
effect of stiffening the links without reducing the cross section of the metal. In.
the case of the link shewn at Figures 4 and 5 where either side of the link may
work upon the sprocket wheel I crank or chamber both sides a' a' but I leave a.
rib a' so as to maintain the line of the links and also the stiffness. These links
may be made quite straight or hollowed out to any desired configuration the shapes.
shown upon the drawings being only examples to which my invention is applied.
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 :-
The improvements in chains for driving cycles, motor-cars and other machinery

page_text: of the connecting side links A formed with one cranked recess a¹ as seen at
Figures 1 to 3 or with two recesses a' a' and a rib a' as seen at Figures 4 and 5
substantially as herein set forth.
