Improvements in Driving Chains for Velocipedes, Motor Cars, and
other purposes, and in the Manufacture of the same.
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 velccipedes,
motor cars and other purposes and in the manufacture of the same and is especially
applicable to roller chains by which the rollers extend the full width that the
links are apart thus bringing the ends of each roller flush against the inner sides
of the links and preventing the teeth of the sprocket wheels from catching against
the ends of the links.
In order that my invention may be clearly understood and easily curled into
practical effect I have appended hereunto a double sized sheet of diawings upon
which I have illustrated several examples of my improved driving chain.
Figure 1 is a plan view of my driving chain shewing the rivet head, protruding
bevond the sides of the links.
Figure 2 is a part sectional plan view of Figure 1.
Figure 3 is a side elevation of Figure 1.
Figure 4 is an edge view of one of the side links as shewn at Firure 1.
Figures 5 and 6 are part sectional plan views shewing mcdifications of the
chain as shewn at Figure 1.
Figure 7 is a part sectional plan view of my driving chain shewing the rivet
leads flush with the surface of the side links.
Figure 8 is a part sectional plan view of a modification of Figure 7 shewing my
method for lubricating the rollers.
In carrying my invention into practice I form the ends of the rollers A with a
aecess or cupped out and then crank or bend or otherwise form the ends b' of the
links as shewn at Figure 4 so as to fit into the recessed end of the rollers A, the
other ends 62 of these links are formed straight and rest upon the cranked or bent.
ends of the next link which is cranked sufficiently so as to bring all the links in a
parallel line. The rivets or connecting pius C are then placed in position, the
ends being rivetted over in the usual manner. These rivets may be hardened
or hardened and tempered or case hardened or made from very hard wire.
At Figure 5 I have shewn the ends cl of the rivets or connecting pins shouldered
or tliinned down so that the ends of the links fit against the shoulders of the
rivets which are then rivetted over in the ordinary way.
In the method as shewn at Figure 61 form the rollers D from tubing and
shoulder down the ends of the rivets or connecting pins so that the ends b' of the
links fit into the ends of the rollers. Or these rollers may be formed from a
metal blank cupped or pressed up by suitable tools the solid end being afterwards
cut off or pierced.
At Figure 7 I have shewn both ends baud of the links cranked or cupped or
otherwise formed so as to fit into the recessed ends of the rollers the heads of the

page_text: rivets being flush or parallel with the sides of the links. The roller D¹ is formed
from a piece of tubing. or a metal blank as previously explained the ends being
opened out so as to allow the cupped ends of the links to fit therein and the ends
of each link may be cupped up as shown at 65. Or instead of cupping the ends
of the links they may be formed as shewn at Figure 8, and the rollers may be
formed from tubing or a metal blank as previously explained. When desired I
may drill the hole in the rollers and form the groove or grooves f around the
connecting pins or rivets for lubricating purposes or I may dispense with thic
groove or grooves and in some cases I may wrap a piece of worsted or similar
material around the groove or grooves so as to prevent any dirt or foreign
matter from entering and also as a means for conducting the oil around the groove
or grooves.
rivets being flush or parallel with the sides of the links. The roller D¹ is formed
from a piece of tuling. or a metal blank as previously explained the ends being
opened out so as to allow the cupped ends of the links to fit therein and the ends
of each link may be cupped up as shown at 65. Or instead of cupping the ends
of the links they may be formed as shewn at Figure 8, and the rollers may be
formed from tubing or a metal blank as previously explained. When desired I
may drill the hole in the rollers and form the groove or grooves fa around the
connecting pins or rivets for lubricating purposes or I may dispense with tlie
groove or grooves and in some cases I may wrap a piece of worsted or similar
material around the groove or grooves so as to prevent any dirt or foreign
matter from entering and also as a means for conducting the oil around the groove
or grooves.
This method of lubricating driving chains is applicable to other than roller
chains.
Instead of rivetting the links together as shown they may be connected together
in the same manner as described in my previous Letters Patent No. 9385 of
1897.
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
CLAIMS:
First: In driving chains for velocipedes, motor ears and other purposeb
recessing or cupping the ends of the rollers and forming one or both ends of each
link so as to fit into the recessed or cupped ends of the rollers in the manner and
for the purpose substantially as hereinbefore described and as shewn upon the
accompanying sheet of drawings.
Second In driving chains for velocipedes, motor cars and other purposes
forming the rollers from tubing or a metal blank cupped or pressed up so as to
allow the ends of one or both links to fit into the ends of the rollers in the manner
and for the purpose substantially as herein before described' and as shewn on the
accompanying sheet of drawings.
Third: In driving chains for velocipedes, motor cars and other purposes
forining a hole or holes in the rollers or blocks either with or without a groove or
grooves on the connecting pins or rivets in the manner and for the purpose
substantially as hereinbefore described and as shewn upon the accompanying
sheet of drawings.
Fourth: The improvements in driving chains for velocipedes, motor cars and
other purposes substantially as herein set forth and as sliewn upon the accompanying
drawings.
