IMPROVEMENTS IN THE MANUFACTURE OF WHEELS FOR VEHICLES." A com-
munication from abroad by Charles Bried, of Newark, in the County of Essex,
State of New Jersey, United States of America.
This Invention relates to the manufacture of wheels for vehicles and parts thereof
from india-rubber, gutta percha, celluloid, or similar materials or compositions, the
wheels being moulded complete or the hub spokes and felly made separate and put
together.
The Invention will be described more particularly with reference to the
accompanying. Drawing, wherein Figure 1 is a side elevation of a complete wheel;
Figure 2 shows the parts separately; Figure 3 is a side view of the hub. A is the
wheel complete; a is the felly; b, the spokes; and c, the hub. The wheel A,
when moulded complete, may be proportionately lighter than when made in
separate parts, as the strength will not be reduced by the mortising required when
the wheel is made in parts. The felly a may be made in sections as usual with
dowel pins for connecting the ends, or it may be made as a complete annulus and
sprung upon the spokes. The spokes 6 are of the same general shape as wooden
spokes, and the hub c will be moulded with mortices as usual for receiving the
spokes; the hub may be fitted with a metal point band and dust cap, or these may
be formed of the same material. The wheel may have a tire if required. These
parts are made so as to be interchangeable, and the parts of the wheel may be used
in connection with wood, as for instance, wooden spokes and felly may be used
with the rubber hub.
The material is vulcanized india rubber, that known as hard rubber or vulcanite;
gutta percha, or celluloid, or similar compositions may be used

page_text: The advantages of the improved wheel are briefly as follows:-The material will
not rot as is the case with wooden wheels and hubs at the joints; all parts of the
wheel are impervious to moisture, so that the parts will not check, shrink, or swell.
The material does not require paint or varnish to preserve it, and it is capable of
bigh polish and ornamentation. The wheel is of uniform elasticity throughout,
and not subject to attacks by worms. In comparison with a wooden wheel it is
lighter, with the same strength.
The Invention is applicable to wheels for any kind or style of vehicles, carriages,
waggons, baby carriages, etc.
Having described the nature of the said Invention I declare that what I claim
as new and desire to secure by Letters Patent is,
1st. A wheel for vehicles made of india rubber, gutta percha, celluloid, or
similar materials or compositions moulded in one piece, substantially as described
and shown.
2nd. A wheel for vehicles having its separate parts made of india rubber,
gutta percha, celluloid, or similar materials or compositions, substantially as
described.
3rd. A wheel hub moulded from india rubber, gutta percha, celluloid, or similar
materials or compositions, substantially as described and shown.
In witness whereof I, the said William Clark have hereunto set my hand
and seal, this Twentieth day of August, in the year of our Lord One
thousand eight hundred and seventy nine:
