Improvements in and relating to Non-regenerative Gas Lamps.
We, THOMAS BUTTERWORTH HARRISON, of 101 Tong Road, Armley, Leeds,
Plumber, and GEORGE WILLIAM SCARR HUDSON, of Stock's Hill, Armley,
Leeds, Plumber, do hereby declare the nature of this invention to be as follows:-
Our invention has reference to certain improvements in and relating to what are
known as non-regenerative gas lamps.
According to lamps of this description the burners are usually arranged in and
around a bulb or chamber from which they derive the gas, and at or about an
angular position of 45 degrees from the vertical. The heat from the burners
ascending and striking upon the under edge or surface of a superposed basin shaped
dome, or deflector.
According to one part of our said improvements the burners are arranged in and
around a bulb or chamber of special or improved construction which construction
consists in providing such bulb or chamber with a tap or valve whereby the supply
of gas can be turned on or off or regulated as required.
Above the burners is a dome or deflector and a cover or canopy above the dome
or deflector, the cover or canopy being separated from the dome or deflector
sufficiently to allow a passage for the escape of the heat or products of combustion
to a ventilating or exhaust shaft or opening in the said cover or canopy, a suitable
fan being arranged at the top of such ventilating opening for exhaust purposes.
The dome or deflector may be constructed of mushroom shape having a turned up
rim or flange, the said dome or deflector being perforated for ventilating purposes,
and for preventing the formation of carbon deposits thereon and is carried upon a
taper (either single or double) or straight tube as required, the said tube being
upon the supply pipe.
Our said tap or valve for regulating or shutting off the supply of gas is as
follows: The lower end of the bulb or chamber is constructed with a stuffing box
through which screws a spindle having a spherical, globular, or other suitably
shaped termination for closing the passage of the gas.
Another part of our said invention consists in a special or improved construction
of joint for suspending such lamps in workshops etc. The pipe union at its top end
is provided with a swivelling joint, similar to a ball and socket joint, which allows
considerable freedom of motion, the union at the lower end is provided with a pivot
which fits into a recess upon a bracket which is secured to woodwork, other
brackets are also employed for holding the union at the required parts.

page_text: The tap comprises a collar T and taper end T¹, both made of cast iron, so that
such tap can be readily turned when required, which it would not be easy to do, if
the tap was made of brass, as the cast iron is less susceptible to the action of heat
than brass.
The dome or deflector D may be used without the cover or canopy E when
required, as in the case of an
66 open" light.
Fig. 4.
A is the lantern the framework of which is preferably made of malleable iron,
and bolted together as indicated, B is the bulb with burners C, and D is the dome
or deflector, the canopy or cover E, being dispensed with. For the purpose of
ventilating the lantern the dome or deflector D has perforations K, and is separated
sufficiently from the glass D' to allow a passage F for the escape upwards of the
heat or products of combustion to a ventilating top G. The top of the lantern
being provided with openings H for admitting cold air by means of enamelled iron
cover J. Cold air may also be admitted, by means of openings J' at each top
corner of lantern, which are protected by covers L, at the same time allowing a
free passage for the cold air. The bars M may also be perforated for admitting
cold air.
The gas supply pipe N is provided with tap, and lantern with lid as ordinary.

Another part of our said invention consists in a special or improved construction
of joint for suspending such lamps in workshops and other places.
The pipe union T at its top end is provided with a swivelling joint U, similar to
a ball and socket joint which allows considerable freedom of motion, the union T at
the lower end is provided with a pivot V which fits into a recess W upon a
bracket X which is secured to woodwork Y, other brackets Z are also employed
for holding the union at the required parts.
From the foregoing description it will be readily seen how our improvements can
be applied for forming what is known as a "cluster light."
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
1. In a gas lamp of the kind herein referred to, the combination, of a perforated
dome or deflector having a turned up rim, and a cover or canopy; whereby part of
the heat or products of combustion are passed through the said perforations, which
are at the top of the said dome or deflector, and part round or past the turned up
rim of the said dome or deflector, both parts being discharged by a ventilating
opening, substantially as shown and described.
2. In a gas lamp of the kind herein referred to, the combination, of a dome or
deflector having perforations at its top, and a turned up rim at its lower portion,
and a cover or canopy; whereby part of the heat or products of combustion are
passed through the perforations at the top of the said dome or deflector, and part
round or past the turned up rim of the said dome or deflector, both parts being
exhausted or discharged by means of a fan provided in connection with a ventilating
opening or shaft, substantially as shown and described.
3. In a gas lamp of the kind herein referred to, the combination of the improved
dome or deflector and a bulb (carrying the burners) having a tap or valve for
turning on and off the gas, substantially as set forth.
4. In gas lamps of the kind herein referred to, the employment of domes or
deflectors constructed as and for the purposes such as shown and described.
5. In a gas lamp of the kind herein referred to, the employment of a bulb (for
carrying the burners) having a valve or tap whereby the supply of gas can be
turned on or off, substantially as set forth.
6. In a gas lamp of the kind herein referred to, the combination of a bulb (for

page_text: carrying the burners) having a tap or valve for turning on or off the gas, and a
ball joint (for suspending such gas lamp) having projections or pins for regulating
the movement of the lamp whilst turning on or off the gas, substantially as shown
and described.
7. The improved construction of lamp or lantern, such as shown and described
with reference to Fig. 4. of the drawings annexed.
8. The improved construction of joint, as and for the purposes such as shown
and described, with reference to Fig. 5. of the drawings annexed.
