as II was before merely suppressing the CYLINDER as
the cards are entirely done away with. 10y tins means
tie manufacturer may realize immense advantages
without any innovation in bis factories
A novel application of the combustion of zinc has
inst been difcotered by Mr. Wenian. he takes ilne
zrc rarres or shaviDgs and forms them into pellet
which. when ienited affords brilliant and 1t is said,
a steady light for Photographic purposes
UNITED STATES.
JAMES RANKIN OF Detroit Michigan, has made an
invention, the obest of which is to produce greater
regularity in the motion of marine engines during
rough weather 1t is evident that when seam yes
eel is lying across the tro,ghs Of the sea, when the
waves run high her paddle wheels during portion of
tie tine will be deeply submerged while at intervals
tley i'll be nearly out Of the water Ihls must of
necessity produce very unequal rate OF motion IN the
engines and the object OF the Inventions 10 counteract
sUeh q tendency Tie inventor proposes TO accom-
plish this by suspending, near the p'dde-wheels
float connected with throttle valve III the steamplpe,
80 that when the greatest area OF paddeboaId OF pro
peller is submerged, the buoyancy Of the float VIII
cause it rise and open the val e but when the wheel
rises from the water the float descending by its own
weight will close the valve partially, and thus eoun-
ttI8ct the diminished resistance.
j. c. RoBIE of Binghanton, n. \. has invented
an improved turn.tabe for Railroads. 1t consists in
balancing the platform of the turntabe upon the roller
carriage beneath it by which it is supported and
upon which it revOyes, in such a manner
that either end of the platform may be depressed
80 as to rest upon bearing provided for it, while an
engine OF other carriage is being received upon or DIS
charged from it, Between tie roller carriage and plat
form On opposite sides of the center, are placed &C.
centres which are arranged as to support the plat
form ON level previous to it's being turned, holding
il firmly in that position, or to elevate one side and
depIess tie other upon ITS bed
Two plans have lately been made public for feed
ing paper printing presses One is the invention OF
d. b. HAzRLTON of Charleston, S. C., and consists in
having cylinder provided internally with series of
longitudinal chambers arranged parallel with the axis
oftle cyder In these recesses the air is alternately
EXHAUSTED and condensed by connection with fan
mist m or aby equivalent device and tie periphery OF
the cylinder is perforated with small holes connecting
with them that its exterior will present an alter
nately attracting surface BY this means, during its
rotation it can be made TO take up and discharge sheets
Of pager as required in feeding 10 the press
Il. CLAIK Of New Orleans, La. is the inventor OF
the Otle Of these feeders This invention consists IN
detaching or lcosening sheet Of paper from the pie
underneath it, 10y giving it backward and forward mo-
tion previously to its being operated upon by feed or
pressure rollers or any other devices for conveying II
TO the press This effect is accomplished by means oil
arms shOd with India rubber or its equivalent by
means Of which II loosened from the plie wheh ~ Is
further passed along the rotation OF pair OF narro"
cylinders. We disposed to consider this very
coed invention.
-TNocH BURT of Manchester Conn has invented
cLcckloom for weaving fancy goods, the novelty OF
which consist in having the leyers jackters below
the web a on shaft parallel with nd at or about YER
teal pare with the lel cloth making line, as to
produce an even shed both at the top and bottom and
render the shifting Of the jacks from the said levers
sure thus avoiding the jar OF the machinery and obvi
strg the liability Of the Jacks hanging on the DANCES OF
tie levers
S. A briggs Of Detroit, Mich has invented an
my royed attachment to pianofOrtes which consists
first in the combination of a series of metallic tongues
or springs with tie pia1Oiorte other sringed instru-
uent in such manner that tongue and string are
struck simultaneously by hammers acuated by sin
gle key second, in actuatng the hammers when
,trike he TONGUE by means oi Jack of any suitable
form ATTACHED to the damper OF IT'S corresponding
string whereby tie said hammer Is caused 10 strike
by tie rising O the daupeT when LeplanOiOrte action
h brought into play aud thus the tongue and string are
struck simultaneously
GEORGE NELSON OF Boston Mass hiss ingeEted an
srrangeme Mt for tie ventilation Of rail car by which the
dust is e1clsded. Ills invention consists in having
two or more ranges OF ponges other capillary par
ti,iops arranged and combined with cstern of water
BY which they will be Kept constantly mostened and
an Opsn mouthCd case. made Ia communicate with the
interior Of the aud the surrounding atmO phcre so
as 10 operate when tie car is in melton
-JosEIH MARKS Of Boston, Mass. has invented an
Improvement in piston valves and steam passages in
cylindrical steam chests lie constructs a steam chest
with continuous circular ports pasase both for the
Induction and exhaust steam arranged 20 keep up
constant and cqsa pressure of steam upon both ends,
and the periphery or outer surface OF cylindri-
cal piston valve which travels in tie bore Of the same,
and By which il secured large area Of port BY a
very small movement Of the valve, and this wheth-
or the said valve be used as n msin valve, cut
90. or throttle valve. The inventor also claims
tie combination of piston valve composed OF
two heads. which 60 clofely in the bore of the cir
culnr steam chest constructed with circular ports or
ras,ncef by lich large exhaust space is occurred
without Increasing tho size Of the steam chc-t unduv.
nd b. which means alone pro' ifion il made for tho
r.,iit Of tie ,sL1ur steam .lto ~. chamber.
