Improvements in Regenerative Gas Lamps.
I, WILHELM BREYMANN, of 104 Skalitzerstrasse, Berlin, Germany Regenera-
tive Lamp Manufacturer, 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:—
This invention relates to improvements in regenerative gas lamps, the object
being to promote within as large a circular area as possible the combustion of gas
by means of hot air, the burner being of the smallest possible size and capable of
being produced at the lowest possible cost.
Figure 1 is a vertical sectional elevation of a lamp of my invention.
Figure 2 cross section on line A, B, Figure 1.
Figure 3 cross section on line C, D, Figure 1.
The lamp consists of a cast iron frame or body a furnished with a set of radial
tubes 6 also of a circular cast iron base e connectable thereto, and provided with
a flange fhaving a circular row of air holes g.
The lamp is furnished at its lower end with an ignition piece or nipple k, the
circular periphery of which is provided with small perforations.
The
The cone (porcelain) is fixed to the base e by means of a bayonet joint; 1, mare
the inner and outer reflectors, the glass globe n being fixed by the screws w.
cylinder p is secured to the projection hand by resting on the body a shuts off
the air from the products of combustion. The cylinder p supports the canopy_q,
the chimney r, and the smoke cap or covert with its support s. The gas inlet
pipe u is fixed in the cast iron base e, and passes through the body a to which it is
secured by the nut v.
In action, the gas issues horizontally and circularly within the lamp globe, is
ignited at k, and the flame is drawn through the annular opening of the inner
shade and around but away from the porcelain cone i towards the hollow space d
so as to assume a bell or tulip shape; the hot products of combustion in their
upward travel impinge against the radial tubes 6 and pass through the chimney.
The air required for combustion is drawn through the opening and is divided
into two parts, one of which is conveyed upwards through the heated tubes 6 into
the chamber c, and thence to the flame, which assumes a tulip shape through the
depth of the porcelain cone i and contracted opening of the shade l. The other
part of the air is drawn in a cold state through the holes 9 into the glass globe n
cooling its walls, and reaches in a heated condition the outer part of the flame.
The glass globe is furnished below with a circular opening closed by a small ball
or marble o placed loosely over the same, so that by raising this marble with the
igniting device, the lamp can be readily lighted without having to open the glass,
as at present. This burner produces with a supply of 141 litres of gas, a light of
51-3 candle power.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. In regenerative gas lamps, the division of the inflowing air into an inner air
stream which is heated by the radial tubes b and an outer air stream which enters
the glass bell through the holes g in the flange fand cools its walls while at the
same time it is heated as set forth.
2. In regenerative gas lamps, the conversion of the horizontal circular flame
gas
„….sed ho the air draught from the chimney to

cup i as described.
