Improvements in Wheels for Vehicles.
We, WILLIAM STEPNEY RAWSON of 86 York Street Westminster, Electrical
Engineer, JACOB BONN of The Limes, St. Stephen, Hounslow, Middlesex,
Engineer, and FRANCIS DRAKE LESLIE Receiver and Manager of Woodhouse
and Rawson United Limited, of 74 Coleman Street, in the City of London,
Accountant, 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 :-
Our invention relates to a construction of wheel for a carriage or other vehicle
with spokes secured to an iron or steel tyre of T section, as we shall describe
referring to the accompanying drawings.
Fig. is a front view of part of the tyre with socket for attachment of spoke.
Fig. 2 is a transverse section of the tyre and side view of spoke socket.
Figs. 3 and 4 are central sections of the spoke socket on planes at right angles to
each other.
Fig. 5 is a plan at X where the socket is divided, Fig. 6 is a plan looking into its
mouth at Y, the tyre and elastic cushions being removed. Fig. 7 is a corresponding
plan with the cushions in position.
Fig. 8 is a front view, and Fig. 9 is a plan looking from below of one of the
cushions.
On the end of each spoke S, which is shewn as made of wood, we fix a metal
socket A. which terminates in a projecting dovetail a made slightly taper in plan to
wedge into a correspondingly tapered dovetail groove formed in another socket B.
The tyre T, after being bent to a circle with its ends welded or otherwise joined,
is subjected to the action of a punch and die which makes a hollow t on the one
side and a prominence on the other side of its rib, at a point corresponding to the
centre of each spoke. The socket B is made with a shaft b projecting inwards from
each side and leaving between them a groove admitting the rib of the tyre, this
groove having in its middle a curved part to fit the punched up part t of the tyre.
The shelves bb are stiffened by ribs 6. Into the mouth of the socket B are fitted
two cushions C of elastic material, such as caoutchouc, shaped so as to bed on the
shelves b and their ribs and having curved ends c which overlap the ends of the
shelves b.
с
Both cushions are equal and similar having hollows c to admit the punched up
part of the rib of the tyre, and having projections at their bases to fill up the
space left between the edge of the rib of the tyre and the face of B. Thus either
cushion will suit for either side of the tyre. Instead of punching up the
part of the tyre in order to prevent it from moving, the socket B may be made
with ears indicated by the dotted lines 63 in Fig. 1, and pins may be passed through
holes in the cars and the rib of the tyre, the holes in either being radially slotted
to allow for movement of the tyre in compressing the cushions.
When the sockets A have been fixed on the spokes and the tyre T fixed in the
other sockets B, the two parts of the wheel are put together by first clamping the
parts B to the tyre, compressing the cushions C, and then introducing lateraliy
the small ends of the dovetails a into the large ends of the dovetail grooves in B
and driving them home, after which they are prevented from being shaken loose
by a rivet R. The clamps being then removed the wheel is complete. Obviously
the spokes may be of material other than wood having the sockets A secured to
them in any convenient manner.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A vehicle wheel having an iron or steel tyre of T section bedded on elastic
cushions in sockets attached by dovetails to sockets fixed on the ends of the spokes,
substantially as described.
2. The herein described method of putting together the two parts of the wheel,
by first clamping the cushioned sockets on the completed tyre and then connecting
the spoke sockets to them.
