PROVISIONAL SPECIFICATION.
Improvements in Electrical Igniting Apparatus.
We, HUGO HIRST, Electrical Engineer, and ARTHUR ERNEST ANGOLD,
Electrician, both of 69-71 Queen Victoria Street in the City and County of
London, do hereby declare the nature of this invention to be as follows:-
Our invention relates particularly to the production of a concentrated heat
focus, the energy being derived from any ordinary alternating electric lighting
circuit, and the objects of our said invention are firstly, to obviate the deterioration
caused by the deposition of carbon particles during use; and also to present a
heat focus that is adaptable for lighting cigars, pipes, or for domestic purposes
generally.
'
In carrying our invention into effect, we employ a split nipple terminating in a
flange which is also slotted or divided so that it may present two surfaces
insulated or electrically divided from each other. A circular cap or plate of
platinium, or like metal or alloy of high electrical resistance is mounted upon washers
of asbestos or any suitable refractory substance capable of retaining its shape
under rapid alternations of temperature. The platinium or other cap is preferably.
of convex form exteriorly, or with a bevelled edge, which encloses the washers
which are held in place by a central pin, the head of which slightly projects above
the surface.
It is obvious that the platinium or resistance cap closes the circuit across the
split, slot, or other division of the nipple.
Now the essential features of our said invention are, firstly, to employ a solid
plate or piece of platinium or other metal of high resistance instead of laminations
or wire, and secondly, we adapt the nipple so made to a small transformer or
inverse coil, and we may or may not use a press or other hand switch. The whole
apparatus may be constructed in such a manner as to be a light and handy
appendage to the electric light fittings of a building as a cigar lighter and for
kindred purposes.
One of the advantages of our invention is in the fact that instead of a heavy
flexible secondary conductor being necessary, a light flexible may be used, since
the transformer is made so as to constitute the handle of the igniter, and may be
ornamented or shaped to suit various conditions of adaptation.
The nipple itself may be bent, elongated, or otherwise made to conform to any
special purpose to which the apparatus may be applied.
In order to render the insulation perfect, and prevent deterioration due to
atmospheric and external influences we prefer to close the nipple in by an external
plate of insulating material, the secondary conductors being fixed to the two
sections of the flange, by any of the ordinary methods of coupling.
We do not confine ourselves to the actual conformation or design of the device
forming the subject of our invention, but desire to hold the essential features of
the combination of a small transformer with a heat focussing nipple, and also the
formation and insulation of the focussing nipple as a whole.

the point of fusion. The terminals of the primary wire, o and u are connected to
the circuit by means of a flexible or other conductor.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is;
First. In electrical igniting apparatus the combination of a transformer having
a primary winding a secondary winding b and core c within a portable case d, with
a split nipple N on a flange F with dividing insulation A, substantially as and for
the purposes as herein described with reference to the appended drawings.
Second. In electrical igniting apparatus, the construction and use of a split
nipple N, and split flange F with a connecting cap C of high electrical resistance,
backed with washers of refractory material W. in combination with a transformer,
the sections of the divided nipple N being connected to the secondary winding
thereof, substantially as herein described and shown by the drawings hereto
appended.
Third. In electrical igniting apparatus, the combination of a transformer,
nipple and switch, the coupling of which is according to the diagram Figure 4,
and the general arrangement of the several parts substantially as herein described
and shown by the drawings hereto appended.
Dated this 22nd day of September 1896.
