St,ou and Fire Regulators much resemble .
s.fe,y valve They consist Of long lever, to which
weight Il attached. This lever s sctsd upon near Us
fuLcrum By large valve placed under il, which may
,tse ard fall email distance without letting steam
out az 10 the case for piston 10 cylinder The END
of the lever is united by slender rod TO the crank OF
a dsnper or of a valve in the chimney. When the
presture Of steam increases in the boiler the vsve
rises the lever does the and closes the camper
when the pressure decreases the valve comes snd
opens the camper The weight on the lever IS movs-
bic and may be adjusted for any degree OF pressure.
The older patent dated 1917, is Of Timothy C!ark.
The valve Ia an elastic vessel inclosed in cylindrical
ca,rp on which is the fulcrum Of the lever. Ovefthe
elastic vessel is cy ndrical plate, wita projecting
pin on top that rests sgsnst the lever one Inch rom
the fulcrum. The lever is four feet long Thus the
motion of the end Of the lever is forty eight times that
tf the valve The elsstic vessel is composed OF So
res of annusr plates sodered to each other at their
inner and outer edges they made of brass, thin
enough to be elastic This vessel is ,oldered on the
end Of steam-pipe, and packing Of joints is re
qued II the solder used is not too sof, this valve
may last for years without any attention.
The Valve of W. S. Gales Regulator is circular

The Valve of Pstrck Clark, exhibited by the Patent
Steam and Fire Regulator Company, is also disc OF

Nv this arrangement lorg stroke is obtained. The
pin between the lever and the piston s separate
piece il rests in deep recess in projection cast on
the piston. This projection sdes in box as guide
to ipsu. the straight motion of the piston The effect
Of the lever is to increase the motion only fifteen times.
This s claimed as great advantage by the exhibitor,
for the reason that the bearings of the valve in the
smokepipe are rusty and that to overcome their ffc
ton the force corresponding to short leverage is ne
csssary
At the Palace all the regulators are in the smoke
pipes of the boilers that move the machinery, and be.
ing ewy put up they work with equal ease.
Whites Valve is an elastic pipe foot long and
three inches in diameter which isps'sd horiz zontaly
il semi.crcular trough il is long square plate
fla. at top and underneath. The center Of this
plate is cas-. bearing for rod, with sknife-edge
which acts against the lever The elastic pipe is made
Of several lsyers Of hemp fabric, made steam tight
with India rubber It s closed at each end by means
Of plugs The fabric and plugs are pressed together in
the bo1et Of pillow blocks placed at each end. One Of
these blocks is fas. the bed plate, and the steam
enters through the plug in it. The other block Is tree
to move to and fro as the pipe becomes longer or
shorter BY being more or less full Of steam. Tne lev

The Regulators sold by the Patent Steam and Fire
Regulator Co. are substantially built and reliable in
st.umerts. We are informed that they are eIten.
siyely used in New England and that in this city
alone five hundred have been put up.
Timothy ClaIks and Whites Regulators are also
good and are or be manufactured TO rival those Of
the Company. The Only reason we can fod why they
have as yet msde little progress is that they beorg to
individuals not possessed of sufficient capital to bear
the expenses attending the introduction Of new thing
The con, ,umption Of fuel in boiler provided with
regulator il per cent less than when without it. This
instrument is also a protection against explosion, -
when the pressure of steam rises it dampens the ire
and thus prevents the pressure from rising higher.
Flerrble Packing Rings (Ps.ritk Clark, patented.
These rngs are metallic and are intended for stuff
ing boxes To make them, long strip Of thin brass,
timed On both sides is wound eight times around
cylinder the diameter OF which is little more than
twice that the pistonrcd 10 be packed. The ring
thus formed is pressed into fiat band sixteen times
the thickness of the brass and this band Is curved In
ring around the pstOn-rod. The ends are cut in the
shape Of grooves ard epons to lock into each other
without overlapping. vertical stufing box is filed
by placing at the bottom and around the rod ring OF
hemp, above it the metallic ring, and above this
another ring Of hemp strip Of pure lndia-rubber Is
wound tightly round these three rings until the whole
equals the diameter of the stufingbox. Tee metallic
ring occupies about twothrds of the length of the
sufipg-bo This Few packing is in consequence q
compound packing two-thirds in metal aud one-.bird
in hemp. This makes it difficult to ascertain whether
or not the flexible ring n steamtght in other words,
if the metal lie the main packing, or only accessory TO
tie hemp. This method of packing is cheap, and may
prove good for email and middlesized steam engines,
but for large machines il is inferior TO that actually in

the inventor both in theory and in practice, and for
usefulness is second TO none. On this account il is
much to be regretted that the exhibitor did no. refrain
