statement from the owner. giving the date
on which the tire was purchased by him
together with the name and number of the
wheel on which 1t was used and that all
imperfect or defective tires shall IL re-
ferred to us before any claim for repairs
or replacement shall be allowed We
agree to repair free of charge any tire that
can be repaired, provided such tire is de-
lyered to US, transportation prepaid. This
guarantee continues for six months from
the date OF sale by agent, but expires in
any event on May l, 1893 This agreement
does not apply to tires into which any So
called anti-leak preparation has been in
troduced."
The rubber tire is rapidly coming into
use on light carriages of all sorts. cabs,
hacks, ambulances, hotel omnibuses, and
on the new motor wagons. A great va
riety Of opinion, however, is expressed as
to the future of the pneumatic tire on We
hicles Of the heavier class. As in the
case OF bicycles, the aim OF inventors and
manufacturers is to displace as far as
possible the use of the solid tire in favor
of the pneumatic. In regard to the for
mer, its use is now an accepted mark Of
excellence in the heavier vehicles A
prominent carriage-maker in this city de-
clares that a four-wheeler of high finish,
such as he turned out year or year
and half ago with steel tires, would not
almost necessity. Pneumatic tires for
the lighter carriages are an undoubted sue
cess, both here and in England, but the
difficulties to be overcome in the case of
the heavier ones have compelled some
good carriage makers TO take a dubious
view. 1t is only just to say, however,
that they have not so thorough an appre-
citation of the difficulties of the problem
as those who have been better acquainted
with its strictly scientific aspects. With
these latter the simple facts Of success
in few instances goes far. and ought
to go far, to anticipate sue
cess on a very large scale. They
have no doubt whatever that the
pneumatic tire on vehicles between 1000
and 1900 pounds in weight win soon be in
general use. One large firm OF tire
makers, whose works are in district
where unusually good roads are the
rule, claim a. decisive success.
They have fitted cabs, hacks, ambulances,
hotel omnibuses, and motor wagons
with tires that give perfect satisfaction.
Generally speaking, the greater the weight
of the carriage, the greater must be the
diameter of the tire and the greater the
increase in the layers of fabric. Partly
on account of very good roads. this con-
Germ found less difficulty in making d sue
cess of their work; but they had to use an
extra quantity of material which consd-
erably increased the cost. Special can
vas, special quality of sea island cotton,
and extra fine Para rubber were employed
The tire was fastened on by bolt going
through the felly and screwing into nut
which had been embedded in the canvas
of the tire, thus serving the purpose of
preventing the latter from creeping as well
as strongly holding it. Cement could
scarcely be used with safety in a tire of
this weight, as it could not prevent the
tire from creeping or slipping off the rim
in case of very rapid motion.
AS It stands to-day, therefore, the dis
placement of the solid rubber tires in
favor of the pneumatic on heavy vehicles
seems to resolve itself into a question of
better roads and increased cost of con-
struction. Contrary to ordinary opinion,
English roads are not as well adapted as
our own for this purpose. their greater
hardness making them less fit for the
pneumatic tire than roads with a softer
foundation. In spite of the opinion of
carriage -makers, it may be held that the
immediate future will see a greater use of
the pneumatic tire on heavy carriages.
Those who are most conversant with the
considerations of material and structure
see a strong ground for success in the fact
of what has already been done, and the
probability that 1t will create the demand
and attract the capital which are sure to
result in cheaper production. In this city
alone more than a million dollars were
spent on the 10000 rubber tires now in use
Although the proportion of pneumatic
tires i'm this number is not known, it is
certainly increasing +, and with the pro-
gress of invention Will become larger every
year.
