COMPLETE SPECIFICATION.
Improvements in Driving Chains for Velocipedes, Motor Cars, and
other purposes.
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 driving chains for velocipedes,
motor cars and other purposes by which I materially lessen the cost of manufacture
and greatly reduce the weight.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto a double sized sheet of drawings upon
which I have illustrated several examples of my improved driving chains.
Figure 1 shows three links of my improved driving chain.
Figure 2 is a plan view of Figure 1.
Figures 3 and 5 are similar views to Figure 1 showing modifications of my
driving chain.
Figures 4 and 6 are plan views of Figures 3 and 5 respectively.
Figure 7 shows another form of driving chain with the links connected together
in the centre by wires.
Figures 8, and 10 show different methods of connecting the links of driving
chains together with wires.
Figures 11 and 12 are part elevations of the wheels.
In carrying my invention into practice I form the links A of my driving chains
from sheet steel or other metal by suitable tools with the projection a¹ on the
underside of each or I may form two projections a¹ and a² as shown in plan at
Figure 4. These links are then connected together by the side plates B and the
rivets b. Or I may form a recess or slot a³ in the ends of the links and insert
the connecting links at and then rivet them together. Or instead of connecting the
driving links together by side plates or links I may connect each link by the
wire a the two ends of which are headed at a as clearly shown at Figure 6, or
I may use two pieces of wire to each link one piece on either side and head the
ends of each piece. Instead of forming the projections a' on the links A I may
form them on the side plates B or on the connecting links a*.
At Figure 7 I have shewn another method of forming the links of my driving
chains. In this case I extend the sides of the links at a' and connect them
together by the wires a³.
The wheels to be driven by my driving chains as hereinbefore described are
formed with transverse slots or recesses w¹ on the periphery as shown at Figures 11
and 12 in which the projections a' fit and in the case of the chain as shown at
Figure 71 also form a parallel groove w² around the centre of the wheel for the
wires as and the centre portion of the links to fit into the sides a' which drive the
wheel fitting into the slots w¹ as in Fig. 13.
At Figures 8, 9 and 10 I have shown my improved method for connecting the
links together of driving chains to be used with the ordinary sprocket wheel. In
this case I connect the links which are formed out of sheet steel as herein before
mentioned by the two wires a and a⁰ and in some cases I may form the ridge all
on the sides of the links as shown at Figure 9 so as to prevent any side play

page_text: -or I may form the groove a¹ and secure the wires in the groove as shown at
Figure 10.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
First. Driving chains constructed with one or more projections such as a' on the
underside of each intermediate link which take into slots or recesses in the driven
'wheel in the manner substantially as herein before described and as shown upon the
accompanying drawings by Figures 1 to 6 inclusive.
Second. Connecting the links of driving chains together by wires in the manner
substantially as herein before described and as shown by Figures 5, 6, 7, 8, 9 and 10,
on the accompanying sheet of drawings.
Third. Driving chains constructed in the manner as shown at Figure 7 on the
accompanying sheet of drawings.
Fourth. The improvements in driving chains for velocipedes, motor cars, and
other purposes substantially as hereinbefore described and as shown on the
accompanying sheet of drawings.
Dated the 21st day of January 1897.
