I, DANIEL MACFIR of 2 King Edward Street London, in the County of Middlesex,
Gas Engineer, do hereby declare the nature of this invention to be as follows:-
Regenerative gas lamps as hitherto constructed have been adapted only as pendants
from ceilings, bracket arms or the like and are not applicable for upright or vertical
attachment to gas pillars or other forms of gas fittings wherein. the lamp must have a
support under and be supplied with gas through the said support and from below the
line of flame.
This invention has for its object to adapt the regenerative form of gas lamp to
upright attachment upon pendants, gasaliers, brackets, and other like supports and for
use as a pillar lamp either within or out of doors, and for this purpose I connect to
any form or size of such lamp an attachment consisting of a lamp supporting body
composed of two or more arms which at their upper ends are connected to the lainp by
a collar or ring and at their lower ends to the pillar, pendant, gasalier, bracket or
other support the lamp being therefore held above the support.
The arms. have any desired contour according to the shape of the lamp and they
may be separable into sections and connected by couplings or like arrangements. One
of them constitutes the pipe through which gas is supplied, the collar or ring at the
upper ends of the arms having a passage way leading from the arm to the burner. At
any desired point in the supply arm of the supporting body a gas governor is or may
be placed for the exact regulation of the quantity of gas fed to the lamp and the lower
end of the said supply arm communicates. with a combined feed and bye-pass tap so
constructed that the passages for supply of gas to the lamp when in full illumination
and the bye-pass passage for the supply of gas to the igniting jet are both contained in
the plug of the tap. The main supply passage is formed in two branches at right
angles to each other these meeting in the centre of the plug, and the bye pass passage
which is of smaller diameter is in line with one of the said branches the arrangement
being such that when the main supply passage is open the bye-pass passage is entirely
cut off.
Under a modification the combined tap may be dispensed with in the improved
attachment and the supply of gas both to the lamp and igniting jet regulated in any
ordinary manner.

Improvements in Attachments for Regenerative Gas Lamps.
1, DANIEL MACFIE of 2 King Edward Street London, in the County of Middlesex,
Gas 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 :-
This invention relates to improvements in attachments for regenerative gas lamps
and to the application thereto of the gas supply and bye-pass arrangement hereinafter
described and it has for its object to better adapt the said class of gas lamp to upright
fitting on pendants, gasaliers, brackets and other like supports and for use as a pillar
lamp either within or out of doors the invention at the same time providing for the
insertion of volumetric regulators easily accessible for cleaning removal or adjustment
without disturbance of the permanent attachment.
On the accompanying drawings figure 1 sheet 1, shows one form of the attachment
constructed in accordance with the invention and which may be applied to any form or
size of regenerative lamp the attachment consisting of a lamp supporting body or
frame composed of two or more arms A, which at their upper ends are connected to
the lamp by the ring or collar B, shown in plan on a larger scale at figure 2, and in
vertical section at figure 3, the ring serving as a junction piece between the funnel C,
and part D, of the lamp or being fitted on the said parts. The upper ends of the arms
are screwed into the said ring at E, and to their lower ends a tap F is attached the
said tap being connected to the pillar, pendant, gasalier, bracket or other support in
such a way that the lamp stands above or out from the said support. The arms A,
have any desired contour according to the shape of the lamp and as seen at figure 1
they may be separable into sections and connected by couplings G, or like arrange-
ments. One of the arms A, constitutes the pipe through which gas is supplied the
collar or ring B, having a passage way H figure 3, leading from the arm to the burner
and at any desired point in the supply arm A, a volumetric gas governor is or may be
placed for the exact regulation of the quantity of gas fed to the lamp or as seen at
figure 4, sheet 1, the governor I may be applied or connected to the tap or cock F',
in which case the arms A are attached to or spring from the governor and not from
the cock as hereinbefore described with reference to figure 1. The cock or tap F in
either case is a combined feed or supply and bye-pass tap its plug being so constructed
that the passage for supply of gas to the lamp when in full illumination and the bye-
pass passage for the supply of gas to the igniting jet are both contained or formed
within it.
One arrangement by which this is or may be effected is shown by figures 5, 6 and 7,
sheet 1; figure 5 being a view to a larger scale than figure 1, of the plug a, whilst
figures 6 and 7 are cross sections of the plug and barrel showing respectively the
supply to the burner of the lamp turned off and on. The supply passage through the
plug a, is formed with two branches b, c, at right angles to each other and meeting in
the centre of the plug and the bye-pass passage d which is of smaller diameter is in line
with the branch c, the arrangement being such that when the main supply is open to
the burner of the lamp as at figure 7 the bye-pass branch.d, is closed or shut off.

page_text: To control or regulate the volume of gas passing through the branch d, a screw e,
passing through the plug a, is provided the end of the said screw entering the branch'd
so that by turning the screw the area of the passage is increased or diminished or
entirely closed to extinguish the jet at will. To prevent the igniting jet from going
out in shutting off supply to the main governor a passage is or may be ground round
the plug a, as at ; figure 5, from c to figures 6 and 7, which passage is shut off
when the bye-pass passage d, comes opposite the supply arm A.
Figure 1, sheet 2, illustrates in vertical section and figure 2, in longitudinal section
of the plug a, a modification of the combined supply and bye-pass tap shown on
sheet 1. With this arrangement a passage b, is made through the plug for the supply
of gas to the main burner and at right angles to the said passage the bye-pass passage
is formed. From the outer end of the passage d a channel e, extends partially
round the circumference of the plug a, and from one end of the passage b, a like
channel fis also made partially round the plug so that when gas to the main burner
begins to be cut off a supply passes through the channel e into the passage d thence
through the passage b, to the channel and thence to the passage g, in the barrel of
the cock to the igniting burner.
Besides being applied to regenerative gas lamps the supply and bye-pass taps here-
inbefore described may be adapted to any ordinary gas apparatus where a bye-pass
arrangement is desired and with the modification last described the burner inay be
inserted direct into the end of the passage h, figure 1 sheet 2, in the barrel of the tap
the bye pass acting as a flash light which is ignited only when the main burner is
about to be extinguished.
Figures 3 and 4 sheet 2 represent arrangements whereby regenerative lamps may
be supported from horizontal attachments in accordance with my invention, A being
the supporting arms, B the collar or ring connected to the lamp, F the combined
supply and bye-pass tap and I the volumetric governor.
Under a modification the combined tap may be dispensed with in the improved
attachment and supply of gas to the lamp be turned on and off in any ordinary manner
and under a further modification the collar or ring B may be dispensed with in which
case the arms A, connect with the lamp above the funnel at the usual inlet tube.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The improved attachment for regenerative gas lamps consisting of the frame A,
connected at one end to the lamp by a ring B, and at the other end to a vertical or
horizontal support substantially as described with reference to figures 1 and 4, sheet 1,
and 3 and 4, sheet 2, of the appended drawings.
2. The general arrangement and combination of parts consisting of the frame A,
ring B, combined supply and bye pass tap F and volumetric governor 1 in an attach-
Ι
ment for regenerative gas lamps substantially as hereinbefore described with reference
to sheets 1 and 2 of the drawings annexed.
3. A combined supply and bye-pass tap constructed substantially as described with
reference to figures 5, 6, and 7, sheet 1, of the accompanying drawings.
4. A combined supply and bye-pass tap constructed substantially as described with
reference to figures 1 and 2, sheet 2, of the appended drawings.
