Improvements in the Manufacture of Wheel Fire-lighters.
We, EDWARD PARRY STEVENSON, of 13, Hyde Park Place, Gentleman, and
WILLIAM BENJAMIN PINCHING, of 50, Great Percy Street, King's Cross Road,
London, W.C., Mechanical and Electrical Engineer, do hereby declare the nature,
of our said invention to be as follows:-
"
This invention relates to circular or wheel" fire lighters, formed of pieces of
wood tied together and dipped in melted resin or other inflamable material; and
its object is to effect improvements in the manufacture of the same.
According to our invention we group a number of laths of wood or composition
in a suitable position and secure them by suitable chucks or other means in such
a manner that the ends project a suitable distance beyond the support. On being
suitably rotated a groove preferably V shaped is cut in the outer portions of
the wheel. In this groove the string is inserted and secured by tieing or by
friction produced by tension without tieing. The wheel is then sawn or cut from
the laths and dipped in melted resin or other inflamable material as usual. We
prefer to coat the string with tar or some other suitable adhesive material, to
increase its binding properties.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Wheel Fire-lighters.
We, EDWARD PARRY STEVENSON, of 13, Hyde Park Place, London, W., Gentle-
man, and WILLIAM BENJAMIN PINCHING, of 50, Great Percy Street, King's Cross
Road, London, W.C., Mechanical and Electrical Engineer, do hereby declare
the nature of our said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement: --
This invention relates to circular or "wheel" fire lighters, formed of pieces
of wood fastened together and dipped in melted resin or other inflammable
material; and the object of our invention is to manufacture wheel fire lighters
in an improved manner, whereby a cheaper and equally efficient article is pro-
duced.
According to our invention we group a number of laths of wood or composition
such as compressed sawdust or a mixture of sawdust and pig potatoes or other

page_text: inflammable compound approximately longitudinally parallel and in such a
manner that a section thereof is the desired pattern or shape of the wheel fire-
lighter.
Fig. 1 of the accompanying drawings illustrates a suitable machine or apparatus
for holding, grooving and stringing the laths, and severing the wheel from the
grouped laths.
Fig. 2 is an elevation of a portion of the laths, illustrating the method of
grooving and stringing.
The laths are held in position temporarily in hollow mandrels, chucks, or
tubes 'b, the forward end projecting a suitable distance beyond the support. A
suitable rotary or other cutter c is caused to cut a groove d (preferably V shape),
around the circumference of the laths; the laths are then fed forward by any
suitable means, such as a suitable grippere and lever mechanism f, and,
simultaneously with the cutting operation of another groove, a jute "tyer," string
or wire is run round in the first mentioned groove by a rotary string or wire reel
or drum g, and secured by friction with the sides of the groove, or by tieing, or
hitching. The laths are again fed forward and the outer end cut or sawn off,
or nearly so, by circular saw h capable of swinging out of action, the portion
detached (or nearly so) forming the wheel strung together and ready for dipping
in the melted resin or the like.
Fig. 2 shows a portion of the grouped laths a grooved and strung, the diagonal
grooves carrying the "tyer" from one circumferential grooved to the other:
it will thus be seen that the action of cutting off the wheel also severs the "tyer."
The laths are fed through the various operations of grooving, stringing and
cutting all of which are acting simultaneously at different portions of the laths.
whereby a continuous action is obtained, other groups of laths being inserted
and held in the holders or supports as the group, being operated upon is 'fed
forward.
We prefer to coat the tyer with tar, or some other suitable material which will
increase its frictional or binding properties.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. The improved method of manufacturing wheel fire-lighters, consisting of
first grouping or bundling a suitable number of laths in the particular formation
or position desired, then cutting annular grooves, in said laths, securing the laths
by a suitable "tyer" in said grooves, and severing or nearly severing the wheel
from the end ready for dipping in the melted resin or other inflammable sub-
stance, substantially as set forth.
2. The improved fire-lighter manufactured in the manner substantially as
herein before described.
