COMPLETE SPECIFICATION.
Improvements in Oil Lamps.
A communication by GIUSEPPE PIERONI of 17 and 18 Via Poli, Rome, in the
Kingdom of Italy, Lamp Manufacturer.
1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool & 6 Bank Street,
Manchester, both in the County of Lancaster, & 323 High Holborn, in the
County of Middlesex, Civil Engineer, 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 oil lamp forming the object of this invention is shown on the drawings
accompanying the present Specification and which form part thereof.
In these drawings:-
:―
Figure 1 is a front view and
Figure 2 is a section.
The two concentric tubes A. B, the former of which is a little higher than the
latter, are fastened together at their lower part, and whilst, by the tube C they
form a continuation of the oil reservoir, placed in any suitable position, they also
enclose the wick D. A disc E, carried by a rod F, is soldered or fixed in any
other suitable manner in the interior of the tube A and has, for its object, to extend
or subdivide the flame which is fed by three currents of air, the first of which
passes into the interior of the tube A, the second passes through the annular space
comprised between the tube B and the third tube G, and lastly, the third current
passes between this last tube and the glass tube H, which is supported by the
gallery I. The third tube G, contrary to the arrangement in other lamps of the
same kind, has a relatively larger diameter, so that the annular space comprised
between it and the tube B will be enlarged; it is higher than the tubes which hold
the wick, and it is slightly flared out at the top; this is so as to avoid an excessive
heating in the burner, such as takes place in lamps of the same kind which have
not a similar arrangement.
The tube G carries a ring I, fastened to its lower part in any suitable way,
whereby the tube G is secured to the cylinder B; stops m m limit the descent of
the ring L, so that the flanged end of the cylinder G is maintained at a suitable
height in relation to the upper edge of the wick. The gallery I is also attached to
the same tube G by suitable means.
Finally, a knob N with a rack and pinion serves for raising or lowering the wick
in the tubes A. B.
The improvements in lamps above described may be applied to any oil lamp on
the old system by the addition of the third tube G and the disc E.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated
to me by my foreign correspondent, 1 declare that what I claim is :-
1. An oil lamp having three tubes A B G and a glass tube H, all arranged in
such a way as to create a triple current of air for feeding the flame which is
attenuated or sub-divided by the disc E.
2. In an oil lamp constructed according to Claim 1, the special form of the tubes
and of the glass tube, as shown on the accompanying sheets of drawings.
Dated this 28th day of November 1891.
