NEW INVENTIONS.

49, "A railroad track of his uyenron. Ias improve
men consists in making the track OF four rails instead
Of two. or one gusge within another. Each car has
trusks of two widths and there Is double safety
.ssiIst running on. The weight OF the locomotive
being borne On the doube track may also DO greatly
augmented, and much higher rate OF spec attained
than II now possible. Il Is stimatd that road built
In this manner nigh; De travofsed with security St
from 100 to 80 miles per hour. The expense would
not be double that of IN ordinary track a. lighter
rails may be used.
NIw KsIrTIsG MAcHIsE-Mr. L. b laey oil Balls
ton Spa, in this State, late proprietor Of the we'll
known establishment, a, that place for The manufacture
OF knitted gcod- has produced admirable machine
.or knitting in continuous tabe, which seems likely
entirely 70 supersede the present method Of knitting
In fist sheets and sewing tesether. Neither form Of
machine yerfets salabe goeds without the subsequent
aid of The shears and nee,lle but the masbine
must be apparent turns me kbi, iabricin form
more nearly approaching that desired and requiring
much le.. Objectionable scam. patent was applied
for by Mr. Bailey on The l2th Of the present mouh,
and small working model that intended Tor the Pat
ert Office merely, has since been placed or exhibition
in the Crys Palace. This model IL inches square,
is tie only machine yet built, and Is in daily opera
ton at that place knitting eontin ually around sud
eddng TO The length Of piece Of hose about three or
four inches in diameter. This Is about the sze h ap-
pears usually required for socks, while under-shrsa
require The cylindrical portion or the boiy to be
about twelve inches diameter. This machine nov
built has been found 10 work successfully At We
ltcy az high % so revolutions per minute in other
worcs Il suits around the stocking % times per
minute and as there % stitches IN ono round, Il
follows that IRE machine knits 500 stitches per ma-
ME, or "a in second. iolerable idea OF its mOdus
opersn6i may possibly be obtained from briei in
sIection.
PHEIps. SrEAy C0cE.-Mr o. c. Phelps Of No. u
Haryard.pace, Boston, il the inventor Of cock de-
signed 10 take the place Of tho ordinary ones in al
most every situation whore considerable pressure Is
eap,riereed. The object is TO compel the press ire OF
The fluid to keep the device always light In passing
through this cock the auid, whether sieam water or
gas tur1s right angle, and tho axis OF the plug IS IN
line with that part Of tho pipe through shch tho ad
il received. The plug is coBca aud partially hollow,
the larger and hollow end being preserved for the
r. epiion Of the iud which is Of course discharged
through hole In the side. From This description il
will b. evident that the plug must be inserted from
the inside the stem TO which the handle Is attached be-
Ing merely a continuation OF tho snaller end. This
invention sppears to be particularly applicable AZ
test cocks in high pressure boilers
TIE ESGiSEs OF TIE BRAND0S The new pro-
pell,r Brandon, Of Gla'gox, which lately made her
frt trip TO this port is provided with dooble or in
fact quacrup o engines, built by Mossrs Randolph,
Elder 4 Co of that city, on the double expansion,
Dsuauy kpown in lhis country "a the Worth plan,
and which have been generally believed in this vi:
einiy to be rapidly becoming obsolete The Brandon
has four engines, all double acting and standing Ia
vertical position st considerable distances apart in
massive framing Ufca.t iron In the forward pair the
port line receives the fresh steam from the boor
end discharges i, into the starboard and larger one,
while In The AFTER pair this arrangement is reversed,
and the starboar ia the smaller or high pressure cyn
,ier. The two starboard engines are connected to
ersnks keyed at right angles OF the ends Of stou.
\ oft Iyng horizontally fore and at overhead. The
mort eng nc are connected o similar shaft, and each
Of these sheds esry largo wheels nearly opposite esch
other with wooden ccgs, which mech into o saauer
pinion on tho propeller shaft below. The stoan is
admitted into TIE smaller cylinders at pressure OF
sbout 20 Js aboye that Of The stnospsere, and OK
pspdpg by the lap OF tho valve merely diDshes its
pressure 10 shout Is when The stroke 10 completed, at
which time the valve opens, admitting the steam to
the same end OF the corresponding )@pessure engine,
then on the opposite center. This second engine "a
designed TO expand the steam to Low pressure as
is economically practicable, tho stroke OF piston in al
the gnes bong feet and the diameter OF the high
pressure while that OF tho lowpressure 81 inches
The ratio OF the cspa titles OF the high and low pres
sure cylinders being about G. to 81 tho steam may
be supposed 10 be finally expanded IN about that ratio
and The eject Of each pair is theoretically equal to
that Of single cylinder Of 10 inches diameter in which
The steam il cut on al iBO6bs Of the stroke and eK-
pnnde1 through the remainder. There are two verti-
cal arpumps one each side, worked by cccentr!cs
On the upper shafs There are many details Of con-
siderable novelty, among which may be mentioned a
set OF small valves or cocks suitably connected for
working or rather for warming" the engines by
hand.
Dr.. GoRRIEs APPARATCs FOR MAKiSG lcE.-
Among the novel machines lately produced in our
immediate vicinity, few perhaps are more worthy Of
brief notice than the engine FOX producing ice n the
tropics, patented by John Gorrio N. d., Of Apaaeh
cola Fla in 1851. machine Of considerable size has
been lately constructed for the inventor by Mr. II. f.
Boeder OF this City, at the Chelsea Iron Works, late
Mott Ayres in Twenty -sixth.st. Some persevering

powerful agent, has since been copied into almost
every newspaper from Bunkumvile TO Botany Bay.

which, although well known 10 be possible has never,
