Improvements in Wheels for Vehicles.
I EDWIN JOHN PINNOCK of 10 Union Square Islington, London, N.,
Wheelwright do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the construction of wheels for carts
carriages and the like and has for its object the strengthening of the said wheels,
and means whereby the spokes may be fastened therein for the purpose of easily.
replacing them when broken without the necessity as is now the case of removing
the tyre disjointing the felloes, and other work now necessary in fitting in new
spokes, thereby saving time, expense, and unnecessary labour.
In carrying my invention into practice I so construct the hub that it can be easily
separated at the place where the sockets or mortices are made for receiving the
tenons of the spokes so that when it is desired to adjust therein new spokes the
hub may be so separated as to allow of the spokes being slipped into the sockets or
mortices designed to receive them, the portion of the hub removed being thereupon
readjusted so that the spokes are again securely fastened in the hub.
The other end of the spokes engaging with the felloes of the wheel I propose
adjusting and fixing to the said felloes by means of a piece of metal of suitable
length and width flanged at both sides and forined to lap over the felloes at each
join thereof the same being provided with a cylinderical projection forming a
socket to take the end of the spoke.
The advantage of this method being to dispense with the holes at present formed
in the feloes and which materially reduce the strength of the wheel and in place
to provide the cover above referred to, of any suitable material, to fit over the
felloes at each joint thereof for the purpose of engaging with each spoke and also
to more securely bind together the joints of the wheel rim, the said cover being
fixed thereto by any suitable means.
As my improvements are capable of some modification without departing from
the principle thereof I do not restrict myself to the precise form and placement of
the several parts thereof.

I EDWIN JOHN PINNOCK of 10 Union Square Islington London, Wheelwright
5 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 improvements in the construction of wheels for carts,
carriages and other vehicles and has for its object means for fastening or securing

page_text: the spokes therein whereby they may be easily replaced by new ones when broken
without the necessity of having to remove the tyre, disjointing the felloes, and
other work now necessary in fitting in new spokes, thus saving time, expense and
unnecessary labour.
In carrying my invention into practice I construct the hub of two parts or
portions which can be easily separated at the place where the sockets or mortices
are made for receiving the tenons of the spokes, so that the latter can be readily
slipped into the said sockets or mortices, the portion of the hub removed being
thereupon readjusted and fastened in position by bolts or otherwise so as to securely
hold the spokes within the hub.
I fix the other end of each spoke to the felloe of the wheel by means of a metal
socket formed with flanges to lap over the sides of the felloe preferably at each
joint thereof and fixed thereto by means of bolts rivets screws or otherwise.
By means of my invention I dispense with the mortices hitherto formed in the
felloe, thereby increasing the strength of the latter and permitting of its lighter
construction and by placing the sockets aforesaid centrally with the joint of the
felloes to support the same the durability of the wheel rim is increased.
In the accompanying sheet of drawings wherein like letters of reference indicate
corresponding parts
Figure 1. represents a side view of a portion of a wheel according to my
invention.
Figure 2. is a side view of the fixed portion of the hub to a larger scale and
Figure 3 is a side view of the back plate or removable portion.
.
Figure 4 is a face view of the hub and back plate fitted together.
Figure 5 is a side view of a portion of the rim or felloe with spokes attached.
Figure 6 is a cross section showing the spoke attachment and
Figure 7 is an end view of the flanged socket.
a represents the hub formed of a metal casting fitted on to the wooden centre of
which b are the spokes and c the rim or felloe of the wheel. The hub is constructed
in two portions a and a¹ the latter being removable.
The part a is formed with the mortices or, sockets a² for receiving the inner
ends of the spokes, intermediate recesses a³ being formed in the hub and plate a
for lessening the weight. d are the screws or studs for attaching the parts a a¹
together.
The hub a is provided with lugs at and the plate a¹ with corresponding mortices
or slots a. These lugs serve to assist the studs d in keeping the parts a a¹
together, the slots a³ permitting the latter being placed in position on the hub, a
slight turn of the plate a¹ then disengaging the slots with the lugs as shown in
Figure 4.
ee (Fig. 5.) are the metal sockets for attaching the outer ends of the spokes to
the rim or felloe c and e' are the flanges formed therewith for embracing the rim
of the wheel and fixing the sockets thereto by means of bolts or screws f.
Should it be required to replace a broken or worn out spoke by a new one, the
part a' of the hub is detached from the part a by first unscrewing the studs d and
then turning the part a¹ so as to bring the slots a opposite the lugs a*; the damaged
spoke is then removed from the sockets a² and e, and a new spoke fixed at one end
in the socket e, the other end being forced into its mortice or socket a² in the back
face of the part a of the hub, the part a' is then again fastened in position against
the said face thus fixing the spoke firmly in the hub.
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 ;-
1. In the construction of wheels forming the hub with a removable portion
substantially as described and for the purpose specified.
2. In the construction of wheels the combination of the two parts a a¹ forming
the hub, the mortices or sockets a², the lugs at and the slots-a and the sockets -e

page_text: for receiving the outer ends of the spokes and attached to the felloe of the whee
substantially as described and for the purposes specified.
3. The improved construction of wheel substantially as described and shown in
the accompanying sheet of drawings.
