Improvements in Illuminating Apparatus for Burning the Vapour
of Mineral Oil.
I, SYDNEY PITT, of Sutton, in the County of Surrey, Gentleman (a communica-
tion to ine from abroad by La Compagnie Internationale pour l'Exploitation des
procédés Adolphe Seigle of 4 Rue des Archers; Lyons in the Republic of France)
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:-
The present invention is applicable to illuminating apparatus for burning vapours
of mineral oil and especially to portable apparatus for giving light by the
vaporisation or spraying of combustible liquids when the open burner is at a height
too great to be readily reached.
Such apparatus is usually formed of a reservoir which serves as a base and
supports a vertical pipe, at the end of which is a burner. To allow of access to
this latter for lighting, cleaning or other purposes, the pipe is either jointed which
allows it to be bent back at a point in its length or it is telescopic or again steps
are arranged along a stay or otherwise.
These several arrangements all have objections which the present invention
remedies by avoiding in these apparatus every sort of moveable joint and causing
the burner to be lowered near to the ground by an oscillating or rocking movement
given to the entire apparatus including the reservoir.
The annexed drawing shows several arrangements which may be adopted.
Figure 1 shows in elevation an apparatus mounted on rollers.
Figure 2 shows a simpler arrangement suitable for small apparatus..
Figure 3 shows a modification of the preceding arrangement in which the
apparatus rocks onto an iron foot.
Figures 4, 5 and 6 are detail views showing certain modifications.
In Figure 1 the reservoir A, the pipe B and the burner form a rigid whole
provided with two trunnions a resting on a frame D mounted on rollers as shown,
or which may be fixed.
n
It will be understood that the whole apparatus is kept in a vertical position when
at work by the weight of the reservoir or by a bolt and that it suffices to incline
the apparatus to the position shown in dots to be able to clean and light the
burner. The trunnions a instead of being a single pair as shown in the drawing
may be doubled one pair being placed on each side similar to those of a sideway
tipping ballast waggon.
A handle E fixed to the reservoir facilitates the, operation, and the apparatus
may be kept at any desired height of a dog F or by any other means.
If the tube B be of great length or if it be exposed to the wind equilibrium
may be maintained by guys G G fastened to a collar b on the tube, and to the
Frame D by any suitable hooking arrangement; to incline the apparatus one of
these guys is unhooked and takes the position shown in dotted lines in Figure 1.
His a support upon which the tube B may be made to rest for lighting. The
tube B is for this purpose provided with a stop collar b¹ for the support H.
Figure 2 shows a simpler arrangement suitable for small apparatus.
The reservoir, tube and burner still form a rigid whole and are carried by three
egs a' a' fixed to the reservoir A. This latter also carries at its top one or two
upports a² which with the two legs a' upon which the apparatus is turned allow it
o be turned down and rest on the ground in the inclined position shown in dots.
The supports a' may also be replaced by a small moveable stand.

page_text: Figure 3 shows a modification of the foregoing arrangement in which the
apparatus rests upon an iron foot Informed in one with an arched stay I to support
the tube B. This mounting may be fastened down in any suitable manner.
In every case the end 63 of the feed tube is beut as shewn in Figure 3 in, such a
manner that it will always remain immersed in the liquid when the apparatus is
inclined.
•
Figures 4 and 5 show respectively in end and side elevation a reservoir A.
provided with a fixed or jointed heel-piece K which prevents it from turning when
the apparatus is in the position for lighting.
Lastly Figure 6 shows a reservoir A in which the portion of the tube B
referred to in the other figures is not rigid, but is replaced by a flexible metal.
tube L provided at its lower end with a leaden ring sufficiently heavy to curve-
the tube L on rocking the reservoir in such manner that its lower end is always
immersed in the liquid whatever may be the position of the reservoir.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that without
limiting myself to the details of carrying out the invention what I claim is:-
1. A light giving apparatus burning the vapour of mineral oil consisting of a
reservoir, a tube, and a burner, the said reservoir being mounted on trunnions in a
suitable frame which allows the apparatus to be rocked.
2. The combination with the apparatus above referred to of a support. for
lighting substantially, as described and shown in the drawings.
3. In a light giving apparatus burning the vapour of mineral oil, the combination
of legs and supports allowing the apparatus to be turned down as shown in
Figure 2.
4. In a light giving apparatus burning the vapour of mineral oil, the combination
of a foot and arched support allowing the apparatus to be turned down as shown.
in Figure 3.
5. In these apparatus the combination with the reservoir of a
heelpiece as shown in Figures 4 and 5.
fixed or jointed
6. In these apparatus a flexible metal tube placed in the reservoir and carrying
at its free end a leaden ring which keeps the end of the tube in the liquid
whatever may be the position of the apparatus.
Dated this 2nd day of October 1894.
