A New or Improved Appliance for Supporting Burners for Liquid
Fuel.
We, Sir W. G ARMSTRONG, WHITWORTH & CO., LIMITED, and EDWIN LANCELOT
ORDE, Engineer, both of Walker Shipyard, Newcastle upon Tyne, do hereby de-
clare the nature of our said invention to be as follows:-
1
The object of our invention is to provide a swinging or rotating trunnion in
connection with burners for liquid fuel, by means of which the burner may be
supplied with three constituents necessary for combustion, and at the same time
be capable of being swung out of position for purposes of examination, if desired.
According to our invention we fit a long tube, of brass or other suitable metal,
with branches of suitable sizes, the branches being separated by metal divisions.
The openings for the admission of two of the constituents are arranged at each
end of the tube and the third through annular ports in the tube, suitably arranged
joints being provided in the bearing brackets and made fluid tight by means of
stuffing boxes and glands. The trunnion is fixed in a suitable position near the
furnace, and is connected to the burner by means of pipes fastened to the branches
on the trunnion by suitable couplings.
The trunnion with the burner attached, is capable of being rotated upon or
about the longitudinal centre of the tube, the connections with the constituents
being sometimes arranged to be automatically shut off simultaneously with such
rotation. The burner and fittings can then be examined and attended to, as re-
quired, and afterwards restored to their nominal position.

ARMSTRONG, WHITWORTH & Co., LIMITED, and EDWIN LANCELOT
ORDE, Engineer, both of Walker Shipyard, Newcastle upon Tyne, do hereby de-
clare the nature of our said invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
The object of our invention is to provide a swinging or rotating trunnion in

page_text: connection with burners for liquid fuel, by means of which the burner may be
supplied with three constituents necessary for combustion, and at the same time
be capable of being swung out of position for purposes of examination, if desired.
And in order that our said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawing which represents
a longitudinal section of our invention.
We fit a long tube or an analogous device k, formed with passages, 7 for the oil,
m for the steam, and n for the air, each of which terminates in a branch con-
nection to which the burner is rigidly attached. Two of the constituents are
admitted to the trunnion at the ends thereof and the other at a suitable point
in between.
:
As shown, each end of the trunnion is formed conically to fit a correspond-
ing formation of the socket r which also acts as a connection with the main
supply the sockets are suitably and adjustably attached to a convenient fixed
support, such as the boiler end. The inner ends of the sockets are provided with
stuffing boxes s: also suitably arranged ports in the conical ends are provided
by means of which the fluid gains admission to the interior of the ends from the
main supply. The other connection is accomplished by a short sleeve
with packing at both ends and a main connection at w; the interior of the
sleeve admits of fluid surrounding the trunnion which is formed with ports x
through which the fluid passes into the passage n.
fitted
The ports t, t, may be so arranged that when the burner is moved out of
position the supplies of the constituents are automatically cut off thereby.
The positions and arrangements of the passages as also the particular con-
struction of trunnion illustrated may be varied to suit the various types or
patterns of burners.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is :-
:-
Means for pivotally supporting burners for liquid fuel and connecting the
supplies thereto, consisting of a trunnion mounted in sockets or bearings at each
end and formed with passages communicating with the main and branch pipes, the
sockets forming fluid tight joints, and a packed sleeve connection situated between
said sockets, the whole constructed and arranged so that the burner is supported
thereby and so that the constituents are fed thereto and in some cases automatically
shut off, substantially as set forth.
