Improvements in Welding Apparatus.
I, ERNEST GEORGE GEARING, of Penshurst, Clarence Drive, Harrogate, in the
County of York, Engineer and Manager, do hereby declare the nature of this
invention to be as follows:-
The welded joints of tubes from which boiler flues are to be formed are some-
times found to be faulty and it becomes necessary to make the defective portion
sound or to "mend" them as it is called, by re-heating in an ordinary fire and
again subjecting them to the welding operation. In practice it is troublesome
to re-heat the required portions of the tubes, particularly when their defects occur
near the middle of the length of a long tube, and, moreover, during the re-heating
a greater portion of the tube is invariably heated than is actually necessary, the
result being a tedious and expensive process.
Now the object of this invention is to enable the "mending" of defective
portions of the welds of boiler flue tubes, and other articles to be more readily
and economically effected, for which purpose I provide an apparatus comprising
cue or more burners each supplied with gas and air, preferably through separate
conduits as described in the Specification of my former application for Letters
Patent No. 16668 dated July 30th 1898, and each mounted on an adjustable
arm or lever extending from a standard or support.
One arrangement of apparatus which is especially for use in the manufacture
of boiler flues, comprises an upright standard upon which is mounted a vertically
sliding frame. The standard may consist of a couple of channel iron bars ar-
ranged back to back at a distance apart and the frame may consist of a couple
of vertical bars secured side by side, and having near their upper and lower ends
rearwardly projecting arms carrying antifriction rollers running in the channels
of the bars of the standard. This frame is hung from the upper part of the
standard by a chain passing over a pulley block. To the frame as couple of
counterbalanced levers are pivotted one above the other. The lower lever carries
at its free end a water gas burner of the kind referred to and the free end of the
upper lever has, suspended from it by links, a similar burner, which is fixed to a
connecting rod or stay pivotted to the frame at, or about the point of, connection
of the lower lever therewith.
The supply pipes, (gas and air) of the two burners are respectively carried
along and secured to the lower lever, and the connecting rod or stay, the con--
nections with the gas and air mains being effected by flexible tubing. The gas
pipes of the respective burners are connected together also by flexible tubing
as are also the air pipes and the passage of gas and air is controlled by suitably
arranged cocks so that either or both burners may be used at one time. The
levers preferably extend rearwardly between the channel irons forming the
standard and their rear ends which are bent to the same level and in opposite
directions laterally so that they are side by side, are provided with adjustable

page_text: balance weights. These rear portions of the levers serve as handles for moving
the burners towards and away from each other as required. The apparatus may
be variously modified.

I, ERNEST GEORGE GEARING, of Penshurst, Clarence Drive, Harrogate, in the
County of York, Engineer and Manager, 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:-
The welded joints of tubes from which boiler flues are to be formed are some-
times found to be faulty and it becomes necessary to make the defective portions
sound, or to "mend" them as it is called, by reheating in an ordinary fire and
again subjecting them to the welding operation. In practice it is troublesome
to re-heat the required portions of the tubes, particularly when their defects occur
near the middle of the length of a long tube, and, moreover, during the re-heating
a greater portion of the tube is invariably heated than is actually necessary, the
result being a tedious and expensive process.
"
Now the object of this invention is to enable the mending * of defective
portions of the welds of boiler flue tubes and other articles to be more readily
and economically effected, for which purpose I provide an apparatus comprising
one or more burners each supplied with gas and air, preferably through separate
conduits as described in the Specification of my former application for Letters
Patent No. 16668 dated July 30th 1898, and each mounted on an adjustable
arm or lever extending from a standard or support:
One arrangement of apparatus which is especially applicable for use in the
manufacture of boiler flues is illustrated in the accompanying drawings wherein
Fig. 1 is a side elevation; Fig. 2 a sectional plan; and Fig. 3 a section on the
line A A Fig. 1.
I, 1 are a couple of channel-iron bars arranged back to back at a distance apart
and supported upon a suitable foundation 2 so as to form an upright standard
upon which is mounted a vertically sliding frame 3, consisting, in the example,
of a couple of vertical, bars secured side by side and each having two rearwardly
projecting arms 4, one near the upper end, the other near the lower end, which
arms carry antifriction rollers 5 running in the channels of the bars 1, 1 of the
standard. The frame 3 is hung from the upper part of the standard by a chain G
passing over a pulley block G 7 and 8 are counterbalanced levers pivoted one
above the other to the frame 3, respectively at 13 and 13. The lower lever 8
carries at its free end a water gas burner 9 of the kind referred to and the free
end of the upper lever 7 has suspended from it by links 10, a similar inverted
burner 11, which is fixed to a connecting rod or stay 12 pivoted to the frame 3
at, or about, the point of connection 13 of the lower lever therewith.
The gas supply pipe 14 and the air supply pipe 15 of the burner 9 are carried
along and secured to the lower lever 8, whilst those of the upper burner are
carried by the connecting rod or stay 12, the connections with the gas and air
mains being effected by flexible tubing 16 and 17 respectively. The gas pipes 14
of the respective burners are connected together also by flexible tubing 18, and

page_text: the air pipes by flexible tubing 19; the passage of gas to the burners 9 and 11
is controlled by suitably arranged cocks 21 and 22 respectively, so that either or
both burners may be used at one time. The passage of the air is similarly con-
trolled by means of cocks 23 and 24. The levers 7 and 8 preferably extend rear-
wardly between the channel-iron bars 1, 1 and their rear portions, which are
bent as shown to the same level and in opposite directions laterally so that they
terminate side by side, are provided with adjustable balance weights. 25. These
rear portions of the levers serve as handles for moving the burners towards and
away from each other as required. The apparatus may be variously modified.
Having now particularly described and ascertained the nature of the said in-.
vention and in what manner the same is to be performed I declare that what
I claim is:
1. A welding apparatus of the kind referred to wherein burners and means for
supplying them with gas and air are mounted upon arms or levers made adjust-
able substantially as and for the purpose hereabove described.
2. A welding apparatus of the kind referred to in Claim 1 wherein oppositely
arranged burners supplied with gas and air are carried by a pair of arms or levers
pivotted to a frame which is capable of being adjusted along an upright standard,
substantially as described with reference to and shown in the accompanying
drawings.
3. The combination of parts constituting my improved welding apparatus con-
structed arranged and operating as described and illustrated for the purpose
specified.
