PROVISIONAL SPECIFICATION.
Improvements in Elastic Tires for Carriages, Motor Cars and like
Vehicles.
I, ROBERT ADAMS HALL, Schoolmaster, of 113, Brighton Grove, in the City
and County of Newcastle-on-Tyne, do hereby declare the nature of this inven-
tion to be as follows:
1
My invention relates to elastic tires for carriages, motor cars and like vehicles
and it consists in the combination of two or more parts of resilient material of
unequal quality, one or more inferior parts being secured to the wheel rim and
having fixed thereto a part of superior quality constituting the running surface
of the tire, whereby said part can be readily removed and renewed when worn
without necessitating the replacement of the other part or parts, thereby
economising the cost of both production and upkeep.
The invention is applicable to both solid and cushion tires, and according to
one way of constructing a solid tire embodying same, I secure in the wheel rim,
by means of a wire or the like, a ring or band of india rubber of an inferior
quality formed with lateral convexities and a medial cavity wherein the wire
or its equivalent is located. Over this ring or band I arrange another ring or
band of the same material and quality having its outer periphery or back convex
and its inner surface shaped to conform to the adjoining face of the first ring
or band whereto it is fixed. Over and upon this convex-backed or second ring,
I attach a band or ring of superior rubber and of an arched configuration to
wholly or partially enclose the other rings or bands, thereby completing the tire.
In constructing a cushion tire according to my invention, by one plan I employ
a ring or band of inferior rubber which is shaped and secured to the rim as
described in regard to the first ring in the solid tire and to it I directly attach
an arched ring or band of superior rubber fashioned at its inner face to the con-
tour of the adjacent portion of the said ring and celled to procure increased
resiliency.
In both tires, the number of rings or bands of inferior rubber interposed be-
tween the rim and ring of superior material is determined by the weight of the
vehicle and the nature of the road to be traversed, while the rim may be of the
crescent or other appropriate shape but preferably formed with large globular
edges to prevent the tire chafing against curb stones. The securing wire may
be endless or adapted for connection and disconnection in any suitable manner.
The bands or rings are joined to each other in any of the known ways.
From the foregoing, it will be seen that the ring or band of superior material
serving as the running surface of the tire can be displaced when worn and re-
placed without interfering with the other ring or rings constituting the tire
body, so avoiding the great expense attending renewal in existing tires.

Improvements in Elastic Tires for Carriages, Motor Cars and like
Vehicles.
I, ROBERT ADAMS HALL, Schoolmaster, of 113, Brighton Grove, in the City
and County of Newcastle-on-Tyne, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention relates to elastic tires for carriages, motor cars and like vehicles
and it consists in the combination of two or more parts of resilient material of
unequal quality, one or more inferior parts being secured to the wheel rim and
having fixed thereto a part of superior quality constituting the running surface
of the tire, whereby said part can be readily removed and renewed when worn
without necessitating the replacement of the other part or parts, thereby
economising the cost of both production and upkeep.
The invention is applicable to both solid and cushion tires, and both forms are
shown in the two annexed figures, which are transverse sections of a solid and
cushion tire respectively.
In the figures, the same letters of reference designate the same or similar
parts.
Referring first to Fig. 1, according to one way of constructing a solid tire
embodying my invention, I secure in the wheel rim A, by means of a wire or
the like B, a ring or band C of india rubber of an inferior quality formed with
lateral convexities, and a medial cavity wherein the wire or its equivalent B is
located. Over this ring or band (I arrange another ring or band D) of the
same material and quality having its outer periphery or back convex, and its
inner surface shaped to conform to the adjoining face of the first ring or band C
whereto it is fixed. Over and upon this convex-backed or second ring ), I
attach a band or ring E of superior rubber, and of an arched configuration to
wholly or partially enclose the other rings or bands C and D, thereby completing
the tire.
Now as regards Figure 2. In constructing a cushion tire according to my
invention, by one plan, as examplified in this figure, I employ a ring or band of
inferior rubber C, which is shaped and secured, by wire B, to the rim A as
described in regard to the first ring in the solid tire, and to it I directly attach
an arched ring or band E of superior rubber fashioned at its inner face to the
contour of the adjacent portion of the said ring and celled, as at ‹, to procure
increased resiliency.
In both tires, the number of rings or bands C, D of inferior rubber interposed
between the rim A and ring of superior material E is determined by the weight
of the vehicle and the nature of the road to be traversed, while the rim A may
be of the crescent or other appropriate shape, but preferably formed with large
globular edges a, a to prevent the tire chafing against curb stones.
The secur
ing wire B may be endless, or adapted for connection and disconnection in any
suitable manner. The bands or rings C, D, E are joined to each other in any
of the known ways.
From the foregoing, it will be seen that the ring or band of superior material E
serving as the running surface of the tire, can be displaced when worn and re-
placed without interfering with the other ring (or rings C, D constituting the
tire body, so avoiding the great expense attending the renewal in existing tires.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. In a tire, the combination of two or more parts of resilient material of
unequal quality, one or more inferior parts being secured to the wheel rim and
having fixed thereto a part of superior quality constituting the running surface
of the tire, substantially as described.
2. A solid tire consisting in the combination of one ring or band of inferior
material, or two or more such rings or bands, secured to or next the wheel rim
to form the body of the tire, and an outer, ring or band of superior material fixed
thereto to constitute the running surface, substantially as described.
3. A cushion tire consisting in the combination of one ring or band of inferior
material, or two or more such rings or bands, secured to or next the rim to form
the body of the tire, and an outer cellular ring or band of superior material
fixed thereto to constitute the running surface, substantially as described.
