Improved Apparatus applicable to Gas Burners.
JOHN WILLATT 17 Chapel Bar Nottingham, Wine Merchant 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:-
DESCRIPTION OF THE DRAWINGS.
Figures 1, 2, and 3 show respectively the front, side, and back elevations of a
Bunsen gas burner provided with a flat brass or steel ring 1 hereafter referred to.
Figures 4 and 5 show side and back elevations of a Bunsen gas burner provided
with a perforated ring 2 having a toothed rack on its lower edge.
Figures 6 and 7 show front and back elevations of a burner with a perforated
ring 2 having a stud projecting from its side.
Figures 8 and 9 show front and back elevations of a burner provided with a flat
ring 1 having a projecting stud.
Figure 10 shows a vertical sectional view of a Bunsen burner employed in the
Welsback incandescent gas light system.
Figures 11, 12 and 13 show front and side elevations, and plan of a burner
provided with a flat ring 1 having two studs projecting from its side.
Figures 14, 15 and 16 show front, side, and back elevations of a burner pro-
vided with a flat ring 1 in the sides of which the screw threaded stems of two
beaded studs are screwed. The whole of the above described are burners supplied
with gas through vertical feeds.
Figures 17 and 18 show a vertical sectional view and a front elevation of a
burner provided with a perforated ring 2 and supplied with gas through an
elbow feed.
Figures 19, 20 and 21 show a side view, vertical section and plan of a Bunsen
burner provided with a perforated ring 2.
My improved apparatus consists in the employment of either a flat ring sur-
rounding the perforated base of each burner, the ring being capable of being
raised or lowered to entirely cover or partly cover the perforations in the base,
or a perforated ring capable of being partly revolved either way round the
perforations in the base of the burner.
The burner shown at Figures 1, 2 and 3 is provided with a flat ring 1 from
the top edge of which two short arms 3 project each hinged to the upper end
of a link the link at the back is straight and engages with a stud screwed
into a quadrant shaped washer 5 on the back end of the plug of the stop cock,
the link at the front is beat to reach the back of the plug handle 6 provided
with a stud engaging with the lower end of the link.
In the figures the plug of each stop cock is shown in the position it occupies
when the gas is full on, and the corresponding parts in each figure are indicated by
the same figures where necessary.
By turning the lower end of the handle of the plug to the right the gas will be
partly or wholly cut off and the flat ring I will be raised to partly or wholly
cover the air inlet holes in the base of the burner thereby automatically regulating
the flow of gas and supply of air simultaneously.
The burner shown at Figures 4 and 5 is provided with a brass ring 2 having
perforations 3 which coincide with the perforations in the base of the burner,

page_text: a portion of the lower edge of the ring is ratchet toothed to engage with a toothed
washer 4 secured on the back end of the plug of the stop cock. Stops are pro-
vided on the front of each plug so that by turning the plug to one side the gas
will be cut off the light turned out and the air inlet holes in the base of the
burner will be covered, or by turning the plug to the other side a bye pass or small
light is left burning.
Above the upper part of the ring 2 is a ring 2* held by a stud 5 the ring 2*
holds the ring 2 down with its ratchet teeth engaged with the toothed
washer 4. The burner shown at Figures 6 and 7 is provided with a ring 2
perforated as before described having a projecting stud 3 lying in a fork 4
secured on the back end of the plug of the stop cock, the turning of the plug one
way turns out the light and slides the ring to cover the air inlet holes in the base
of the burner, when turned the reverse way the supply of gas is reduced, the air
inlet holes in the base of the burner is partly covered leaving a small light
burning.
The burner shown at Figures 8 and 9 is provided with a flat ring 1 below the
air inlet holes in the base of the burner two studs project from the ring and engage
in the slots of cam plates 2 one of which is secured on the back end of the plug
of the stop cock and the other at the front to the handle of the plug, by turning
the plug one way the flat ring 1 will be raised to partly or wholly cover the air
inlet holes in the base of the burner and at the same time reduce or cut off the
supply of gas and put out the light or if the cam plate is extended as shown by
the dotted lines by turning the plug the reverse way the supply of gas is reduced
and the air inlet holes in the base of the burner are covered in proportion, a small
light being left burning.
The burner shown at Figures 11, 12 and 13 is provided with a flat ring 1 above
the air inlet holes in the base of the burner, studs project from the sides of the
ring and engage with the upper ends of bent links 4, the lower end of the link at
the back engages with a stud in the outer end of a plate 5 secured on the back
end of the plug of the stop cock, the lower end of the link at the front engages
with a stud 6 at the back of the handle of the plug. By turning the plug the
supply of gas may be reduced or cut off to put out the light, at the same time the
ring 1 will be lowered to partially or wholly cover the air inlet holes in the base
of the burner.
The burner shown at Figures 14, 15 and 16 is provided with a flat ring 1 above
the inlet air holes in the base of the burner, two studs 5 are screwed into the ring
and engage with the upper ends of links 4, the lower end of one link engages with
a stud in an arm 7 secured on the back end of the plug of the stop cock, the
lower end of the other link engages with a stud 6 at the back of the handle of
the plug.
By turning the plug one way the light will be put out and the ring 1 lowered
to cover the air inlet holes in the base of the burner, by turning the plug the
reverse way the light may be lowered or turned down to a small light, the ring 1
being lowered at the same time to regulate the supply of air to the burner.
The burner shown at Figures 17, and 18 is provided with a ring having
perforations which coincide with the perforations in the base of the burner, two
studs 3 project from one side of the ring and clip a rod 4 carried by the
crutch 6 of the stop cock plug, the burner being supplied with gas through an
elbow feed 8.
The turning of the plug one way puts out the light and partly revolves the
ring 1 to cover the air inlet holes in the base of the burner, by turning the plug
the reverse way the light may be lowered or turned down to a small light the
ring 2 being partly revolved at the same time to regulate the supply of air to the
buiner.
The burner shown at Figures 19, 20 and 21 is provided with a perforated ring 2
from the side of which a bracket 3 projects, a pin is passed through the bracket
and secured in one end of a link 4, the other end of the link has a pin passed

page_text: through it and secured in the outer end of an arm 5 carried by the upper small
end of the stop cock plug 6 the burner being supplied with gas through an
elbow feed 8.
The turning of the plug one way puts out the light and partly revolves the
ring 2 to cover the air inlet holes in the base of the burner, by turning the
plug the reverse way the light may be either lowered or turned down to a small
light.
In order to regulate the point at which the air is to be turned off, the arm 5 and
the bracket 3 may be placed at any desired angle from the centre line of the
cock and the burner and slots provided in them to give a greater or a less throw
as desired as shown in plan by the dotted lines at Figure 21.
The following advantage results, when the above described improved apparatus
is applied to the Welsback incandescent gas light, the light may be turned down
low the supply of air being automatically reduced at the same time, lighting back,
a flickering light, and the groaning noise heretofore experienced is prevented.
When the improved apparatus is applied to a Bunsen burner employed for chemical
or other experiments the supply of gas and air may be automatically regulated
simultaneously for a large or small flame.
When applied to the Bunsen burners of gas fires, or cooking ranges a large or
small fire or flame may be used without the lighting back heretofore experienced
with the ordinary Bunsen burner when the gas is turned low.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. In Bunsen gas burners the construction and employment of rings I surrounding
the base of the burner below the air inlet holes, said rings having a vertical upward
movement communicated to them to partly or wholly cover the air inlet holes in
the base of the burners substantially as described for the purpose specified and
illustrated in the drawings annexed.
2. In Bunsen gas burners the construction and employment of rings 1 above the
air inlet holes said rings baving a vertical downward movement communicated to
them to partly or wholly cover the air inlet holes in the base of the burners
substantially as described for the purpose specified and illustrated in the drawings
annexed.
3. In Bunsen gas burners the construction and employment of rings 2 having
perforations which coincide with the perforations in the base of the burners, said
rings having a right or left sliding movement communicated to them to partly or
wholly cover the air inlet holes in the base of the burners substantially as described
for the purpose specified and illustrated in the drawings annexed.
