COMPLETE SPECIFICATION.
An Automatic Reignition Apparatus for Hydro-carbon Furnaces.
I, SYDNEY PITT, of Sutton, in the County of Surrey, Gentleman, do hereby
declare the nature of this invention (which has been communicated to me from
abroad by La Compagnie Internationale des Procédés Adolphe Seigle of 147 Rue
de Courcelles, Paris) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This invention has for its object an automatic re-ignition apparatus intended to
be used in conjunction with a sprayer or gasefyer of heavy oils, oils, petroleum,.
schiste oil and the like.
This re-ignition apparatus is placed between the sprayer or gasefyer and the
heating apparatus.
It is composed of a cylinder inside which a truncated cone is fitted. Suitable
openings are arranged as air inlets.
The cylinder is coated inside with a non-conducting lining.
It is traversed by the ignited jet on its way to the furnace and if this flame-
becomes extinguished or interrupted the ignition apparatus preserves its heat for
several moments which permits of the automatic re-ignition of the jet.
All stoppage due to the extinguishing of the flame which frequently happens in
apparatus burning hydrocarbons is thus prevented.
The automatic re-ignition apparatus is shown in the accompanying drawing in.
which;
Figure 1 is a longitudinal central section
Figure 2 is an end view
Figure 3 shews a modification of the apparatus.
In these figures:-
A is the sprayer or
gasefyer of any suitable type.
The automatic re-ignition apparatus consists of a cylinder B combined with a
truncated cone b.
bb are openings for the inlet of air.
6 is a non conducting lining of cement asbestos or other material.
6 is an inner cylinder of thin steel or other metal.
64 is a washer fixed on the end of the cylinder B.
D is a support carrying a clip d in which the cylinder B is held.
is a ring of insulating material.
E is the furnace.
The modification shown in Figure 3 consists in employing instead of the
truncated cone a second cylinder B² of smaller diameter than the cylinder B',.
mounted concentrically in this latter by any suitable means.
Of course the automatic re-ignition apparatus may also be connected to the
prayer in any suitable manner.
Having now particularly described and ascertained the nature of my said
avention and in what manner the same is to be performed I declare that without
limiting myself to the details of construction or to the use of any particular
honconducting material what I claim is :-
1. An automatic re-ignition apparatus consisting of the combination of a cylinder
ined with a non conducting material, with a truncated cone placed inside the
E is the furnace.
The modification shown in Figure 3 consists in employing instead of the
truncated cone a second cylinder B2 of smaller diameter than the cylinder B',.
mounted concentrically in this latter by any suitable means.
Of course the automatic re-ignition apparatus may also be connected to the
prayer in any suitable manner.
Having now particularly described and ascertained the nature of my said
avention and in what manner the same is to be performed I declare that without
limiting myself to the details of construction or to the use of any particular
nonconducting material what I claim is :-
1. An automatic re-ignition apparatus consisting of the combination of a cylinder
ined with a non conducting material, with a truncated cone placed inside the

page_text: cylinder, openings for the inlet. of. air being arranged between the cone and the
cylinder.
2. An automatic re-ignition apparatus consisting in the combination of a cylinder
lined with a non conducting material, with a second cylinder of smaller diameter,
openings for the inlet of air being arranged between the two cylinders.
3. The combination of these automatic re-ignition apparatus with a sprayer or
gasefyer of heavy oils, oils, petroleum, schiste oil and the like, all substantially as
described and shown in the drawings.
Dated this 9th day of March 1896.
SYDNEY PITT.
