The new style tub or method OF ap-
%plication consists of an improved Joiut

ing OF h flues In the fire box. Mr..
Foley. boiler shop superintendent Of
tie Great Northern Railway. Mr..
Wick. shop superintendent Of the
Northern Pacific Railway and Mr.
Charlton, general boiler inspector Of
the salt Lake Railway. have passed
on the invention and they estimate
that IL will save 30 per cent OF the
leaky flue trouble.
The invention consists OF a COM
bination. with a ruc sheet having the
hole tapercc from the fire ~ side.
The hole In the tube sheet will be !-iC
Of an incl larger on the fire o side
than on tho water side OF the sheet.
and by using a flue point OF double
strength and thickness and providing
the point with u lathed off or reduced
portion a. it, outer end, by using . soft
metal gaskct. preferably copper. WITH
In flanre on the water side OF the nue
sheet. by inserting he lathcd off tube
poiut through the Hanged gaslSei IN
back tube sheet and setting the
shoulder OF tho flue point firmly
against the back tube sheet the re-
suit will be "a very tight Joint. Tie

a. Ia the common practice now, and
when the engine is fired up, istead of
pushing the bead away from The sheet
on the fire box side. IL will press
against the shoulder. thus forming a
very light joint. by having the con-
traction pulling against the taper hole
in the sheet and without adding any
extra thickness TO the outside diane.

Of flucs be- one OF the worst and most
responsive sources OF trouble connected
with railroad equipment. \ set uf

as TO keep the engine lu service. The
Coleman method Will save the rail-
ways millions OF dollars every year.
Also. there are other serious losses
