PROVISIONAL SPECIFICATION.
Improved Carriage Wheel for Pneumatic Tyres.
1, RICHARD PALMER, of Polygon Avenue, Ardwick, Manchester Coachbuilder
do hereby declare the nature of this invention to be as follows:-
The fixing of the metal tyre of pneumatic wheels direct on the end of the spokes
by means of spoke sockets with longitudinal flanges, which latter are rivetted or
bolted to the tyre, thus dispensing with the wooden felloe, and the present bulky
and unsightly appearance of the pneumatic tyre on the ordinary carriage wheel.

Improved Carriage Wheel for Pneumatic Tyres.
I RICHARD PALMER of Polygon Avenue, Ardwick, Manchester, in the County
of Lancaster, Coachbuilder, 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 and accompanying drawings:
My said invention refers to carriage wheels fitted with pneumatic tyres.
Hitherto wheels of this nature and for this purpose have been made with ordinary
wooden fellies to which the pneumatic tyre and rim have been applied. The result
has been a carriage wheel of so bulky and unsightly an appearance that their more
general introduction and use have been seriously retarded. The object of my
invention is to produce carriage wheels, that is to say wheels for application to
broughams, landaus, cabs, dogcarts, hansoms and the like, fitted with pneumatic
tyres, which shall be of light and graceful appearance and which shall go far to
remove the objections to their use which have hitherto prevailed.
According to my invention I dispense with the wooden felly altogether and
fix the metal rim which receives the pneumatic tyre, directly upon the ends of
the spokes, sockets being employed to effect the union between the spokes and the
metal rim.
The practical carrying into effect of the invention will be more clearly apparent
from the annexed sheet of illustrative drawings.
Fig. 1 is a cross section of the rim, tyre and socket.
Fig. 2 is a side view of a portion of the wheel rim.
The
The pneumatic tyre, which may be of any suitable design, is marked a.
trough shaped rim to receive the pneumatic tyre is marked b; the socket to receive
the spokes is marked c; and the spoke is marked d.
In making the wheel I fix the spokes d in the hub and place the sockets c upon
the outer ends. I then shrink the metal rim 6 upon the circle of sockets, thus
compressing and securing the spokes. To prevent movement of the sockets I secure
them by rivets e to the rim. The pneumatic tyre a is then secured in the rim and
the wheel is complete.
It will be seen at once, upon comparing my improved wheel with the ordinary
pneumatic tyre carriage wheel with wooden felly, how light and graceful its
Appearance 18.

page_text: To provide for the use of a brake, I may form upon the rim b an annular
projection of a conical or other shape suitable to receive the pressure of the
brake block; or a brake surface may be provided upon the hub of the wheel.
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.
The improved carriage wheel with pneumatic tyre in which the metal rim to
receive the tyre is attached by sockets directly to the spokes, and without the
interposition of the ordinary wooden felly substantially as described and as
illustrated.
