COMPLETE SPECIFICATION.
Improvements in Tire-heaters.
I, WILLIAM BIRT NEVILL, of Salisbury, in the County of Hall and State of
Texas, United States of America, Inventor, 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 tire-heaters or furnaces more particularly to that class of
heaters which use oil, vapour, or gas for fuel. Heretofore furnaces of this
description have been made with expensive connections-such as reservoirs or
piping and gas, vapour, or oil burners-attached.
The object of my invention is to provide a tire-heater which shall be simple and
economical of construction, adapted to the use of gas, oil, or vapour fuel, but free of
all connections for supplying and burning the same.
My invention consists in providing a rotary circular box revolving in a horizontal
plane and carrying a rack, upon which is supported the tire, said box having a
stationary bottom provided with openings to admit the flames of oil, gas, or vapour
burners to immediate contact with a rotated tire.
My invention consists further in the parts and combinations of parts, as herein-
after more fully shown and described.
In the accompanying drawings, forming a part of this Specification,
Fig. 1 is a perspective view of my tire-heater or furnace with the tire-rack
removed.
Fig. 2 is a perspective view of the tire-rack.
Fig. 3 is a sectional view taken on the line a- of Fig. 1 but with the rack and
cover in place.
Reference being had to the drawings, A. denotes a circular bottom plate made
up of four sections as shown in Fig. 1 fastened together by screws n.
, y, denote a cruciform frame mounted upon supports z, and bolted to said
bottom plate by bolts f. x denotes an axle mounted upon said frame.
B, B, denote friction wheels or rollers journaled to a track D, said track being
formed on the outer circumference of the bottom plate by a vertical rim or flange d.
c, c, denote circular openings in the bottom of the bed-plate and serve to admit
the flame from oil, vapour or gas burners. B denotes friction wheels or rollers
journaled in the track D', said track being formed on the inner circumference of
the bottom plate by the vertical rim or flange d'.
H represents the hub of the tire-rack, said hub carrying arms h, to which are
secured broad metal bands G, G, as shown in Fig. 2, Said hub and rack are
composed of two sections bolted together through the flanges y. This rack is
designed to revolve over the bottom plate and is journaled to the axle x, by the
hub H, the bands G, G, riding upon the rollers or friction-wheels B, B, B¹, B',
fixed in the tracks or ways D, D'. K represents a detachable cover provided with
ventilating holes K, four in number.
L, L, denote lamps. The sections A. composing the bottom plate, are preferably
made of sheet iron and joined together as shown in Fig. 1, their edges overlapping.
The flanges d, d', are preferably made of quarter-inch iron and are elevated about
half an inch above the bed-plate. The tracks D D', are about an inch wide. The
rollers B, B, B', B', are about one and three-quarter inch in diameter and journaled
to the tracks so as to project about a quarter of an inch above their surface. One.
of the axles of said rollers B, B, is lengthened to carry a crank handle b by which
the said roller and the tire rack may be rotated. The openings c, c, should be
about two inches in diameter. The bands G, G, of the tire-rack are preferably
made of quarter-inch iron and are about ten inches high. The arms h, are about

page_text: an inch in diameter and are secured to sail band's about three inches above their
bearing-edges. The cover K is made of sheet iron with a rim or flange turned
down. The ventilating-holes K' are about two inches in diameter.
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 !
claim is-
1. In a revolving tire-heater or furnace, a stationary bottom plate having
circular tracks or ways and friction wheels or rollers, and provided with openings
to admit the flames from independent burners to contact with a rotated tire
supported upon a suitable rack.
2. In a tire-heater, the tire-rack, means for rotating the same in a horizontal
plane, a bottom having perforations C, C, and independent burners beneath said.
perforations, substantially as shown and described.
3. In a tire-heater or furnace a tire-rack consisting of the hub H, arms h, and
bands G. G, and means for rotating the same in a horizontal plane, substantially as
shown and described.
4. A. tire-heater having a bottom plate A, provided with perforations C, track-
ways D, D¹ flanges d, d', and rollers B, B, B', 'B', mounted upon a suitable frame y,
an axle x, mounted upon said frame and a tire rack journaled to said axle, said
rack consisting of arms h, and bands G. G, and hub H, and provided with a
cover K, substantially as shown and described.
