I CHARLES GRIEVE MCDOWELL of Warrington in the County of Lancaster Coach
Builder do hereby declare the nature of this invention to be as follows :-
:-
This invention relates first to the method of attaching the spokes to the fellies of
wheels, and secondly to the method of strengthening the joints of the fellies.
In the first place according to my invention I dispense with the wooden spigot at
the outer end of the spoke which is usually let into a hole made through the felly and
held therein by a wedge driven in from the outside, which plan materially reduces
the strength of the folly.
The spokes therefore can be made from shorter pieces of timber.
1 attach the outer end of each spoke to the felly by means of a double socket plate
of malleable cast iron or other metal in the following manner.
The socket plate is made with two side clips which embrace the inner edge of
the felly, and two lugs by means of which it can be screwed to the inner side of the
samo.
Cast to the inner side of the socket plate (or that side nearest the hub of the
wheel), is a socket of such a form and size as will admit the end of the spoke and
about one inch deep (more or less). The inside of this socket is slightly dovetailed
and a saw cut being made in the end of the spoke and a wooden or other wedge
inserted, the spoke is driven home and being expanded by the wedge will be firmly
dovetailed therein.
At the outer side or back of the socket plate a second socket is cast of a cylindrical
form but split at one or two places so as to allow of its expansion.
In the inner side of the felly 1 bore a hole about seven eighths of an inch deep and
of such a diameter as will admit of the reception of the socket last named and I ease
out the inside of this hole lengthwise with a gouge so as to slightly dovetail or under-
cut it. A wedge (preferably of metal) is placed inside the split socket and when the
felly is driven on it expands the split socket inside the hole in the felly and thus a
firm and strong dovetailed joint is made.

page_text: The socket plate is additionally secured in its place by two screws passed through
the lugs and screwed into the felly.
For securing the ends of the felly together for bent fellies, or where only a small
number of long sections are employed I propose to strengthen the joint by means of
a felly plate of malleable cast iron or other metal. This felly plate is made with two
lugs by means of which it is secured by the tyre rivets to the two adjoining portions
of the felly, and two side clips which embrace the sides of the felly covering the
joint. The ends of the sections are dowelled together as usual and the joint is further
secured by a rivet passing transversely through the joint above the dowel and through
the two side clips of the felly plate.

page_text: I CHARLES GRIEVE MCDOWELL of Warrington in the County of Lancaster Coach
Builder 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 :-
This invention relates first to the method of attaching the spokes to the fellies of
wheels, and secondly to the method of strengthening the joints of the fellies.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof.
Fig. 1. is a side elevation (partly in section) of part of a wheel constructed according
to my invention and Figs. 2. 3 and 4 are sections taken respectively through the
lines A-B C-D and E-F on Fig. 1.
In the first place according to my invention I dispense with the wooden spigot at
the outer end of the spoke which is usually let into a hole made through the felly and
held therein by a wedge driven in from the outside which plan materially reduces the
strength of the felly. The spokes therefore can be made from shorter pieces of
timber.
I attach the outer end of each spoke a to the felly by means of a double socket
plate c of malleable cast iron or other metal in the following manner.
The socket plate is made with two side clips d which embrace the inner edge of the
felly band two lugs by means of which it can be screwed to the inner side of the
same.
Cast to the inner side of the socket plate c (or that side nearest the hub of the
wheel) is a socket e of such a form and size as will admit the end of the spoke a and
about one inch deep (more or less). The inside of this socket is slightly dovetailed
(see left side of Fig. 1.) and a saw cut being made in the end of the spoke and a
wooden or other wedge inserted the spoke is driven home and being expanded by
the wedge will be firmly dovetailed therein; or the wedge ƒ may be cast in one piece
with the socket plate as shown at Fig. 1.
At the outer side or back of the socket plate a second socket g is cast of a cylindrical
form but split at one or two places so as to allow of its expansion.
In the inner side of the felly b I bore a hole about seven eighths of an inch deep
and of such a diameter as will admit of the reception of the socket g last named and I
ease out the inside of this hole lengthwise with a gouge so as to slightly dovetail or
undercut it. A wedge (preferably of metal) is placed inside the split socket g and
when the felly is driven on it expands the split socket y inside the hole in the
felly b, and thus a firm and strong dovetailed joint is made.
The socket plate c is additionally secured in its place by two screws i passed through
the lugs and screwed into the felly b.

For securing the ends of the felly 6 together for bent fellies, or where only a small
number of long sections are employed I propose to strengthen the joint by means of a
felly plate & Figs. 1. and 4 of malleable cast iron or other metal. This felly plate is
made with two lugs by means of which it is secured by the tyre rivets to the two
adjoining portions of the felly & and two extended side clips which embrace the sides
of the felly covering the joint. The ends of the sections are dowelled together as
usual and the joint is further secured by a rivet m passing transversely through the
joint above the dowell n and through the two side clips of the felly plate k.
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
First. The construction and use of a double socketed plate in combination with two
wedges for attaching the spokes to the fellies of wheels substantially as hereinbefore
described and illustrated by the drawings annexed, and
Secondly I claim the construction and use of a felly plate with two extended side
clips to take a rivet, passing through the joint transversely, substantially as shown
and described in combination with the ordinary dowel for securing the ends of the
fellies together for wheels with bent fellies or where a small number of long sections
are employed.
