PROVISIONAL SPECIFICATION.
Improvements in the Construction of Elastic Tyres for Cycles and
other Vehicles.
I, DANIEL CONRADE BATEMAN, of Brookhouse Wire Works, Cleckheaton, in the
County of York, Wire Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to certain improvements in tyres suitable for cycles and other
or like vehicles, and has for its objeot, the construction of the same in such a
manner, so as to make the tyre more durable, and remove the liability of destroying
the clastic utility of the tyre by puncture; and to sa arrange the tyre that, any
shocks caused on the cycle or vehicle passing over irregular or uneven roads, are
to some extent absorbed by the elasticity of the tyre.
I accomplish my object in the following manner. The rim of the cycle or
other wheel to which my improved tyre is to be applied, is made concave on the
outer circumference for the reception of the tyre, which I form of light sheet
steel plate, bent to the circle of the wheel rim, and circulur or somewhat elliptical
in cross section; the edges of the plate forming the type being on the inner
circumference, and some distance from each other, thereby giving a certain amount
of elasticity to the tyre, which is strengthened by corrugating in the direction of
the axis of the wheel or at a suitable angle.

COMPLETE SPECIFICATION.
Improvements in the Construction of Elastic Tyres for Cycles and
other Vehicles.
I, DANIEL CONRADE BATEMAN, of Brookhouse Wire Works, Cleckheaton, in the
County of York, Wire Manufacturer, 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:-
My invention relates to certain improvements in tyres suitable for cycles
or like vehicles, and has for its object, the construction of the same in such a
manner, so as to make the tyre more durable and remove the liability of destroying
the elastic utility of the tyre by puncture; and to so arrange the tyre that, any
shocks caused on the cycle or vehicle when passing over irregular or uneven roads are
to some extent absorbed by the elasticity of the tyre.

page_text: In describing my invention in detail, reference is made to the accompanying
sheet of drawings, in which Fig. 1 represents a portion of a metal sheet in a flat
state before it is rolled circular into a tyre. Similar letters indicate similar parts
where they appear.
Fig. 2 is a section through the tyre and rim of the wheel, and
Fig. 3 a side view of a segment of the rim and tyre.
The rim A. of the cycle or other wheel to which my improved tyre is applied,
is made concave on the outer circumference for the reception of the tyre B. which
I form of light sheet steel plate, bent to the curve of the wheel rim A. and
circular or somewhat elliptical in cross section to fit the rim A. of the wheel.
The edges C. of the sheet steel plate forming the tyre B. may be bent and
inserted into a recess formed in the rim A. and secured thereto by bolts or the
like D. somewhat as shown, or the tyre may be secured to the rim in any con-
venient manner and the joining of the two ends of the steel plate forming the said
tyre may be accomplished by brazing or other known means of uniting metal.
The tread of the tyre B. is corrugated circumferentially, that is at right angles
to the axle of the wheel as clearly shown by Fig. 2 at 1. and at each side between
le circumferential corrugations and the rim A. of the wheel, other corrugations F.
are formed at a suitable angle, those shown in the drawings being at right angles
to the circumferential corrugations E, thus by arranging the corrugations in the
manner described, strength is given to the sheet steel tyre B. and by combining
with the corrugations an opening between the edges of the plate on the inner
circumference somewhat as shown by Fig. 2, elasticity and strength is obtained
without the liability of destroying the elasticity of the tyre by puncture.
It will be obvious to persons acquainted with wheel tyres that my object may
be accomplished by reversing the order of the corrugations, that is to say, the
circumferential corrugations E. may be arranged at each side in the spaces occupied
by corrugations F. and the transverse corrugations running at or about parallel
to the axle of the wheel, may be arranged on the trend of the wheel tyre, shown
as occupied by the corrugations E. by which arrangement the strength and
elasticity of the tyre is maintained.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
1 claim is :-
A metal tyre corrugated and arranged substantially in the manner as shown
and described.
