PkEUsATIC SUoTIos APPARATUS FOR lNoDoRoVs
DRlIyIyG-Is French invention about fifteen years
old which for that length of time has been pracced
IN Pari. 1t consists substituting large iron casks
for open carts for the transportation of fecal matters
and in producing vacuum in these casks 50 that the
operation Of loading is performed by simply p!unging
in the ditch the end of pipe from the cask and turn
Ing open cock when atmospheric pressure will force
the matters into the cask. The original plan was TO
have at the factory large airPump worked by steam
which wGs applied to every cask just before 1t left the
place: but a. for obvious such factories are
not suffered in the city il often found that on ar
irving at the place 10 be drained the vacuum had hed
end the cask had 10 be taken back TO the airpump
Messrs. Waldron, Cornell & Co. have greatly i'm
proved this plan and their now building IN Brook
yn will soon be at work in this CITY, First they make
the apparatus less costly by dispensing with wooden
car.frame and attaching the wheels directly to the
iron cask ard secondly, they double the efficiency OF
the apparatus by attaching to each small airpump'
worked by the wheels of the machine This air-pumP
can be worked by hand when the machine Is at rest
The effect of these Improvements Is that the vacuum,
being made and kept up on the way by the working Of
the pump is perfect at the required moment and that
when BY the partial filing of the cask the vacuum has
been reduced too much for efficiency, few strokes OF
tie pump by hand.work will perfect it, and allow OF
the filing Of the cask TO TIE top. by the old process
tie casks could scarcely be more than half filed on an
average.
PRIcr's CAR. CouPLISG.-Dreadful accidents have
happened on railways, to the wonder Of unthink-
ing persons who occasionally hear that they might be
prevented, and will continue to happen so long as
stringent means are not adopted against Railroad
Companies. 1t is known fact that when the inter-
ests and the duties Of individual lie in opposite
directions the latter not sure to be performed
but il aso known that there ore noble exceptions
In the case of company there are none. What
every one of twelve honorable gentlemen would blush
to do company of those same twelve honorable gen.
tenen will do. On inquiry it found that nobody
Gid it; every disapproved of II, but submitted TO
the majority; that nobody started it, &c. In the case
Of Railroad Companies, fault may be much more easily
found with what they do not do than with what they
do These thoughts were impressed on our mind in
examining at the Mechanics Institute model of
tie above-pamed invention. 1t is simple con-
tryapce for raising out of gear the pin by
vl,h one car il attached to another As soon a. the
angle formed by the cars is smaller than that core
spoudpg To the shortest curve of the track. Such
angle VIII never be produced but when at least one OF
the ears il Of the track and, in most cases, when
car runs off the track such angle will be the result,
and the runaway will be separated from the train.
he invention is very well carried out but Is OF that
order of discoveries that do not require genius to be
n sle and perfected If a company had hired ten en-
gineers TO make Al attachment for separating run
away car, the company would had & choice between
ten efficient plans Of doing it. There are lying idle
few dozen of inventions important as Mr. Price tor
the security Of Travellers and there would be good
many more II inventors did not know that 1t is gener-
ally time lost make them. In Prussia they report
one nan killed in year on all the railroads OF the
kingdom. We have here more mechanical genius
than they have in Prussia all We want is to force our
companies to ure it, 10y making them pay heavily for
life.
SroNI-CUTTIyG MACHINE OF LoUIs CAKrLE &
CO. One of these machines for cutting or carving Is
exhibited ia working order at No. "a Water street,
Brooklyn. 1t involves the general features a.
Eastmans viz A row of inclined cutting chises,
striking the in quick succession, the stone being
canied on sliding car, and fed toward the tters.
Tie method Of working the chises in Carriers ma
chine is mat of the togge joint. Each chisel sliding
II =
three Joints or hinges in it. The first joint is on the
head Of the chsel, the second in the middle Of the
rod The third ON the crcse-head. The rod is acted
upon in tie center by two cams having correspond
ing motion, so as to throw it alternately side
tie other of the straight lines. The effect of this is
to give the chsels an up-and-down motion, and to do
il with an immense force. This arrangement i. the
principal point of novelty. In former machines, the
chisels were raised by cams, and thrown down against
the stone by strong springs; here there is theoret
cally no blow, and the chisels merely
pressed against the stone. They work at a
velocity Of five hundred strokes 10 minute
The angle Of the chseframe with the teedtraIne may
be varied according TO the nature of the stone to
be cut We are inclined to think chat this machine is
better calculated than others for making welnished
work but that il requires more power, and u conse
quenty more expensive, when only very rough sur
face is sought for. But this difference of expense il
very likely more than compensated by another result
If the toggle-jont motion, which is that the tools
moved in this marrer do not wear as mucL in day ss
they do in week when they are made to strike.
MARIsE ESGISEs-A prize Of 500 is offered by
the French Academy of Sciences for the best paper
son the application Of steam 20 the navy The
papers are TO be sent in before the first day Of No
vembsr Of the present year. 1t must be remembered
that during the last five years numerous systems have
been experimental on q large scale in the French
navy both regards the motor Itself and the mechau
Ism by which tie power generated is transformed into
a motion Of the vessel. The prize will doub; be
awarded not TO the best treatise the subject, a.
such treeti:es are aid good both in French
ard English, but to the essay which will state the most
remarkab new truth.
