This invention relates to improvements in apparatus as aforesaid wherein a blast
of stean, discharged through perforated pipes, within the flues, is the medium for
sweeping and cleaning the same, and the improvements consist in the use
of Tand+couplings for jointing the longitudial pipes, the said Ṭand +
couplings being perforated, so as to ensure a steam blast at right angles to and also
parallel with the discharge from the perforations of the longitudinal pipes, thus
securing efficient cleansing of all parts of the flues, also in boilers the flues of which
are fitted with water way or "Galloway tubes" placed across the flues and in
irregular line the steam pipes are curved and jointed by T and + couplings,
perforated; the whole being so arranged as to secure the cleansing of the tubes and
Hlues. The head of the Ṭ I place near the bridge its ends being closed save one or
more perforations through which steam is discharged at right angles to the longitu-
dinal pipes its head is also perforated so as to discharge steam at angles to or
parallel with the longitudinal pipes, the + couplings are also closed at their outer
ends except perforations which discharge steam at right or other angle to the
longitudinal pipe and such couplings are also further perforated so as to discharge
steam parallel with the longitudinal pipes.
The Couplings and pipes are tapped and screwed with right and left handed
threads so as to facilitate jointing up the same.

This invention relates to improvements in apparatus as aforesaid wherein a blast
of steam discharged through perforated pipes within the flues is the medium for
sweeping and cleaning the same and the improvements .consist in the use
of T and couplings for jointing the longitudinal pipes the said T and +
couplings being perforated so as to ensure a steam blast at right angles to and also
parallel with the discharge from the perforations of the longitudinal pipes thus
securing efficient cleansing of all parts of the flues also in boilers the flues of which
are fitted with water way or Galloway tubes placed across the flues and in
irregular line the steam pipes are curved and jointed by T and + couplings
perforated the whole being so arranged as to secure the cleansing of the tubes and
Aues. The head of the TI place near the bridge its ends being closed save one or
more perforations through which steam is discharged at right angles to the longi-
tudinal pipes its head is also perforated so as to discharge steam at angles to or
parallel with the longitudinal pipes the + couplings are also closed at their outer
ends except perforations which discharge steam at right or other angle to the
longitudinal pipe and such couplings are also further perforated so as to discharge
the steam parallel with the longitudinal pipes. The couplings and pipes are tapped
and screwed with right and left handed threads so as to facilitate jointing up the
same.
Such being the nature and object of this my said invention I will now proceed
to describe the same in detail and in order that the invention may be fully under-
stood I have hereunto annexed a sheet of drawings and have marked the same
Fig. 1 is oblique view of boiler and piping.
Fig. 2 is a sectional plan of the flue shewing improved couplings
Figs. 3. 4. and 5 are enlarged views of the improved T and +couplings
Fig. 6 is plan of flue having Galloway's tubes the steam pipes being illustrated
in relative position thereto.
'
Fig. 7 is enlarged view of one length of bent and threaded steam pipe.
At A is a T coupling having perforations formed as shewn at B through which
steam is discharged into and along the flue C. At D are couplings perforated
as shewn at E. It will be seen on reference to the enlarged drawings Figs. 3. 4
and 5 that the ends of the T and +couplings are closed and perforations formed in
the ends and front so as to permit the discharge of steam at various angles to the
line of the flue and the Galloway tubes thereon. The T. coupling is near the
bridge and any required number of the couplings may be employed and that the
action and blast of the steam is longitudinal lateral and fan like so as to catch up
and blow the soot grit and dirt along and out of the flue.
Having thus fully described the nature and particulars of this my said invention
together with the manner in which the same is to be performed or carried into
practical effect I would have it understood that I claim
The use of the perforated T and +couplings for the purpose herein described
and illustrated.

page_text: The use of the T and +couplings in combination with the curved perforated
steam pipes and "Galloway" or similar tubes and as described and illustrated by
the annexed drawings-I claim also-The use of perforated curved steam pipes in
combination with Galloway or similar tubes as illustrated & for purpose described
In Witness whereof I the said Robert Sutcliffe have hereunto set my hand
and seal this nineteenth day of November in the year of our Lord one thousand
eight hundred and eighty three.
