Complete Specification Accepted, 6th Apr., 1889
I, JAMES ARNOTT, of Calverley Chambers, Victoria Square, Leeds, Yorkshire,
do hereby declare the nature of the said Invention to be as follows:-
:-
This Invention relates to certain improvements in or applicable to wheels of
vehicles and consists essentially in the formation of the nave of the wheel of an elastic
construction substantially in the manner hereinafter described as distinguished from
the present formation thereof of a rigid construction.
The Invention may be carried into effect according to an advantageous modification
by constructing the nave in opposite parts or sections of wood or other suitable
material a tubular part of one of which also extends centrally through the other part,
and by fitting around such extending part between the said opposite parts a seating
of india-rubber or analogous material which is morticed for the reception of the inner
ends of the spokes which are inserted thereinto, the said rubber seating being so
compacted between such wooden or other rigid parts of the nave as aforesaid as to
be well supported and to offer a sufficient resistance to properly support the weight
of the vehicle.
By such means the travelling of the vehicle is rendered easier, less noisy, and
otherwise more comfortable than with wheels the naves of which are of a rigid
construction, jarring and sudden jolting of the axle and springs being avoided and
the general wear and tear reduced.

Improvements in or Applicable to Wheels of Vehicles.
I, JAMES ARNOTT, of Calverley Chambers, Victoria Square, Leeds, Yorkshire,
do hereby declare the nature of the said 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 to certain improvements in or applicable to wheels of
vehicles, and consists essentially in the formation of the nave or hub of the wheel of
an elastic construction substantially in the manner hereinafter described as
distinguished from the present formation thereof of a rigid construction.
On the accompanying drawings, Fig. 1. represents a central longitudinal section
of the nave of a wheel embodying the present Invention, the upper half illustrating
the modification thereof hereinafter firstly described, and the lower half illustrating
the modification thereof hereinafter secondly described.
Fig. 2. represents a transverse section of the same through about the plane, a, b,
the upper and lower halves thereof respectively illustrating the modifications herein-
before referred to as illustrated by the upper and lower halves of Fig. 1.
According to the modification herein before firstly referred to, the nave is made in
opposite parts, 3, 4, of wood metal or other suitable material, one of such parts being
formed with a tubular extension, 5, of a less diameter which projects into or through
the other part and may be screwed or otherwise suitably secured thereto. As thus
fitted the parts, 3, 4, 5, form an annular recess adapted to receive, slightly distend
and to internally and laterally support an annular cushion, 6, of india rubber, any
suitable compound thereof or any other suitable analogous material, of a sufficient
thickness or substance to be of utility for the purpose of the Invention. The part, 5,
of the nave and the cushion, 6, are respectively morticed at opposite parts for the
reception of the inner ends, 7, of the spokes, 8, the shoulders, 9, of which abut on
the elastic cushion, 6.
According to the modification hereinbefore secondly referred to, the nave may
be made in one piece in a usual manner and recessed, as at, 10, at the parts at
which it is morticed for the reception of a series of independent and corre-
spondingly morticed seatings, 6x, of elastic material, each of which is adapted to
support the shoulders of one of the spokes as represented in the lower halves of
Figs. 1, and, 2.
13, represents a box which surrounds the axle, 14, and passes centrally into and
nearly through the nave of the wheel, and is fitted with a surrounding elastic
cushion, 15, of rubber or other suitable material adapted to prevent the inner ends of
the spokes from being forced into contact with the box.
By the hereinbefore described improved means the spokes are well supported and
offer a sufficient resistance to properly support the weight of the vehicle, the travelling
of which is rendered easier, less noisy, and otherwise more comfortable than if fitted
with wheels having naves of a rigid construction, jarring and sudden jolting of the
axle and springs being avoided and the general wear and tear reduced, besides which
access of water to within the hub is to a great extent prevented.

page_text: 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. The formation of the naves or hubs of wheels of vehicles of an elastic construction
substantially in the manner hereinbefore described.
2. The construction of the nave in opposite parts, 3, 4, forming an annular recess for
internally and laterally supporting an annular elastic cushion, 6, the inner projecting
part, 5, and the cushion, 6, being correspondingly morticed for the reception and
support of the inner ends of the spokes, substantially as hereinbefore described.
3. The construction of the nave in one piece in an ordinary manner with peripheral
recesses, 10, adapted to support independent elastic cushions or seatings, 6×, the nave
and the said cushions being correspondingly morticed for the reception and support of
the inner ends of the spokes substantially as hereinbefore described.
4. In combination with the nave of a wheel formed of an elastic construction
substantially as herein before described, an axle box, 13, fitted with a surrounding
elastic cushion, 15, substantially as and for the purpose hereinbefore described.
Dated this 25th day of February 1889.
