Improvements in Vehicle-wheels.
I, REGINALD WALTER BARKER, of Monument Chambers, King William
Street, London, Middlesex, Patent Agent, do hereby declare the nature of this
invention to be as follows:-
In my invention the rim is rolled circular and channeled or it may be made of
the well-known hollow form.
A band of elastic material, preferably of rubber or analogous substance, is
moulded around so as to completely encircle a rim or band of material which is
somewhat denser than the elastic band, and is of a substance such as cane, or
preferably a dense fibrous or rigid material of a somewhat springing nature,
and preferably placed nearer the side of the gum, which contacts with the
channeled rim, the object of such locating being, first, to secure the maximum
elasticity of material employed and the best economy in its use, and, second, to
accomplish a more secure joining together of all the parts composing the said
wheel-rim, as will be hereinafter shown.
The denser band is lapped or scarfed together obliquely, or when made of two
or more pieces of material, a series of such laps, or made in one or more pieces and
their flat meeting ends are butted together, or they may simply meet, or be pinned
or doweled together, the main object always being to so contract the said core as
to adapt it to be enlarged and diminished in diameter for the purpose of applying it
to the channeled rim.
My improved wheel is assembled as follows: The channeled rim having been
formed and securely attached to its hub by means of spokes in the ordinary
well-known manner, and the combined tire having been prepared as described, the
said combined tire is then applied to the channeled rim by being strained apart at
one or more of the laps or divisions in said core and placed within the channel
of said rim, when the fastening or locking of said tire within said rim is completed
by rolling or closing inwardly upon said tire the edges of the said channeled rim,
thereby completing the wheel. It will be seen that at this time said edges-of
the rim rest against the elastic band where the latter surrounds the inelastic band,
and by this means the complete tire is held on the rim with a somewhat yielding
force. I should have said that the elastic band is moulded so as to be somewhat
thicker outside the inelastic band or 'core' than at its sides, and beneath it, as seen
in the sectional views, and in this manner all possibility of the band condensing
and pulling or rolling out of the rim is avoided, yet as the band is integrally carried
down below and around the core it is impossible for it to become separated
therefrom, and the combined tire is held firmly in place.

band, and by this means the complete tire is held on the rim with a somewhat
yielding force. I should have said that the elastic band is moulded so as to be
somewhat thicker outside the inelastic band or 'core' than at its sides, and beneath
it, as seen in the sectional views, and in this manner all possibility of the band D
condensing and pulling or rolling out of the rim C is avoided, yet as the band D is
integrally carried down below and around the core E, it is impossible for it to
become separated therefrom, and the combined tire is held firmly in place.
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. A tire consisting of a hard core having a curved outer face and a soft rubber
tubular covering entirely surrounding the core and being thickened at the outer
side thereof and rounded on its outer face, combined with a wheel rim below said
base and having flanges pressed against and embedding the thin sides of the rubber
covering opposite the sides of the core, substantially as set forth.
2. A tire consisting of a core in sections having obliquely cut and lapping ends
sliding circumferentially on each other and an elastic and longitudinally
expansive covering on said core, combined with a flanged wheel-rim, substantially
as set forth.
3. A tire consisting of a core made in sections having certain of their ends cut
obliquely and lapping so as to slide on each other and a tubular covering entirely
surrounding said core and thicker at the outer side thereof, combined with a flanged
wheel-rim, substantially as set forth.
