the box or chamber into a plurality of lon-
gitudinal and transverse rows of pockets or
cells 17, each designed to hold a proportion
of the combustible fluid to a certain depth
5 or elevation. It will be understood that the.
flames produced by the ignition of the com-
bustible fluid heat the fluid and the wall 2,
and these flames are designed to impinge
against metallic pins or other equivalent
10 heat conducting elements extending up-
wardly from the bottom wall 2 whereby the
heat is better transmitted thereto, a group
or desired number of such heat conducting
elements being disposed within each pocket
15 or cell.
The purpose of subdividing the box or
chamber into compartments is two-fold,
first to make the effective height or level of
the combustible fluid substantially the same
20 at all points, in order to effect a uniform
heating of the vulcanizing plate 2, which
could not otherwise be obtained, and second
to enable a local' portion of the tire to be
treated without unduly heating adjacent
25 portions which are not under treatment. In
addition to these frictions the thin division
plates 15 further form conducting surfaces
which act in conjunction with the conduct-
ing members 18 to transmit the heat to the
30 plate and thereby render the heating of the
plate uniform at all points in the use of all
of the pockets or cells in the vulcanizing
action.
In the process of vulcanizing a portion
35 of the tire, a suitable quantity of the com-
bustible fluid is placed in all or a desired
number of the cells or pockets, and the sur-
face of said fluid ignited. The fluid itself
is thus heated to the vaporizing point, and
40 thereby transmits heat to the plate 2, while
the flames also impinge against and heat
the surfaces 15, 16 and 18, whereby a uni-
form heating of the vulcanizing plate is
obtained. The device is especially intended
45 and will be found of maximum advantage
in vulcanizing the tread surfaces of tire
shoes or casings, for the purpose of sealing
punctures or blow outs, or to enable cuts or
abraded surfaces to be closed and covered
s0 to protect the fabric of the tire from the
action of moisture, under which it is liable
to rot and weaken the casing. By means
of the device, the surface of the tire may
also be kept smooth in a ready, convenient
55 and inexpensive manner.
I claim:-
1. A tire vulcanizer of the character de-
scribed comprising a receptacle including
a bottom wall or plate which is longitudi-
60 nally and transversely of concavo-convex
form. and of a width to embrace the tread
and sides of the tire, walls rising from the
marginal portions of the convex surface of
the plate and forming a chamber for the
s5 reception of a combustible fluid of a widthto extend across the tread and sides of the
tire, and parallel rows of longitudinal and
transverse division plates within said cham-
ber and subdividing the same to provide
longitudinal and transverse rows of cells of 70
restricted size from side to side of said
chamber.
2. A vulcanizer comprising a bottom wall
or plate longitudinally and transversely of
concavo-convex form, end walls rising from 75
the convex surface of the plate, parallel
side walls connected with the end walls to
provide a box chamber for the reception of
a combustible fluid, said side walls being
spaced a distance greater than the width of 80
the plate and having inwardly projecting
horizontal extensions at their lower ends
connected with the lower portions of the
side walls of the plate, longitudinal and
transverse partitions within the box or 85
chamber subdividing the same to provide
longitudinal and transverse rows of cells
or pockets, and securing means connected
with the depending portions of the sides.of
the plate. 90
3. A vulcanizer of the character described
having a vulcanizing surface comprising a
base plate of concavo-convex form longitu-
dinally and transversely, bottom walls ex-
tending laterally from the sides of said 95
plate, side walls rising from said bottom
walls, end walls rising from the plate and
side walls, said bottom, side and end walls
forming a receptacle for a combustible fluid
open at its side.opposite the plate and bot- 100
tom walls, a plurality of longitudinal par-
titions separating said receptacle into a plu-
rality of central side cells, and transverse
partitions sub-dividing said cells.
4. A vulcanizer of the character described 105
comprising a base plate longitudinally and
transversely of concavo-convex form, bot-
tom walls projecting laterally from the
sides of the base plate above the lower edges
thereof, leaving short portions of the latter 110
depending below said walls, side walls ex-
tending upwardly from said lateral walls
beyond the sides of the base plate, end walls
connecting said base plate, bottom and side
walls forming therewith an oblong rec- 115
tangular chamber, series of longitudinal
and transverse compartments separating
said chamber into rows of longitudinal and
transverse cells, members depending from
the said depending short portions of the 120
side walls of the base plate and arranged
so as to lie on opposite sides of a tire and
wheel to which the device is applied, and
connecting means extending transversely
between said members and provided with 12
means for securing the vulcanizer to the
wheel.
5. A vulcanizing device comprising a vul-
canizing plate, having a vulcanizing face
adapted to lie in direct contact with a tire, 130
