Improvements in Wheel Tyres.
I, CILARLES JOHNSTON REEVES, of the Town of Woodstock, in the County of
Oxford, in the Province of Ontario, Canada, Machinist, 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 improvements in wheel tyres and the object of the
invention is to design a form of tyre, which will take the place of the pneumatic
tyre and have no tendency to slue or be thrown to one side of the rim when turn-
ing, under heavy loads and it consists essentially of a tyre consisting of a
plurality of substantially circular springs arranged adjacent peripherially, having
depressions in the tread portion thereof and encompassed throughout the entire
circumference of the tyre by a steel band, the inner ends of the substantially
circular springs being held in place in recesses between circumferential strips
next the rim and a suitable rubber envelope being preferably provided to completely
cover the tyre, and the parts being otherwise arranged as hereinafter explained:
Fig. 1, is a perspective view of portion of a tyre constructed in accordance with
my invention.
Fig. 2, is a cross section through the tyre and rim.
In the drawings like letters of reference indicate corresponding parts in each
figure.
2 is the rim of a wheel, which is made of wood or any other suitable material
and is provided with an outer peripheral groove 3.
A are the springs, which are placed adjacent to each other and are flat and are
substantially semi-circular in form. The inner ends of the spring A fit into
recesses or pockets b, formed between the circumferential metal strips B and B¹,
which are fitted into the groove 3. The circular metal strip B is substantially
arc-shaped in cross section while the metal strip B is formed with shoulders
by which the pockets are formed. These strips are connected together throughout
their entire circumference by rivets 4. On the ends of the strips are formed the
cross bars B2, which are connected together by the set screws b³, so that such
circumferential strips may be held securely on the rim.
A is a depression made in the centre of the tread portion of the springs A.
D) is a band of steel, which passes through the depressions A around the
circumference of the tread portion fitting snugly in the depressions.
E is the rubber envelope, which forms a covering for the entire metallic portion
with the exception of the rim info which it fits, preferably extending under the
metal strips B and B¹.
It will be seen that the band of steel will be perfectly resilient in itself and
admit of perfect resiliency in the circular steel springs A, and these will, on
account of fitting in the depression A' effectually prevent any portion, or portions
of the springs from slueing either to one side or the other when the wheel is
being turned under heavy loads. This latter feature is of essential importance,
as the rim and wheel are liable, to be broken under heavy loads where the tyre is

page_text: thrown or slued off to one side in turning, the lateral strain being very great in
such a case.
The pockets b into which the ends of the springs A fit, effectually hold the ends
of the springs in place as upon the outer periphery of the springs the tendency
is to throw the inner ends of the springs inwardly. The rubber envelope E
further serves to insure the holding of the springs in place and yet, on account
of being elastic, permits of the depression of the springs under a load.
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 tyre for wheels, and in combination, a rim having a concave peripheral
face, two circumferential strips suitably fastened together, one outside of the
other and fitting into the concave face of the rim, a plurality of divided rings
having their free ends extending towards each other, pockets formed on each side
of the strips by the shoulders in the outer strip, and flat, split, spring rings
lecated adjacent to each other around the entire periphery of the rim and having
their free ends extending into the pockets on each side of the circumferential
strips as and for the purpose specified.
2. In a tyre for wheels, and in combination, a rim having a concave peripheral
face, two circumferential strips suitably fastened together, one outside of the
other and fitting into the concave face of the rim, a plurality of divided rings,
having their free ends extending towards each other, pockets formed on each side
of the strips by the shoulders in the outer strip, and a suitable rubber envelope
or outer tyre extending around the wheel and beneath the inner free ends of the
circular springs and circumferential strips as and for the purpose specified.
3. In a tyre for wheels, and in combination, a rim having a concave peripheral
face, two circumferential strips suitably fastened together, one outside of the other
and fitting into the concave face of the rim, a plurality of divided rings having their
free ends extending towards each other, pockets formed on each side of the strips
by the shoulders in the outer strip, and depressions formed circumferentially in
alignment in the tread portion of the split, spring rings and an encompassing
strip bounding the rim and fitting into the depressions as and for the purpose
specified.
