oconotips.-Among the many admirable and in
genious models and specimens of machinery, perhaps
there is none truly useful and applicable to the
purposes of every day life than that of the Osclatng
Locomotive, which is to be seen on the side shelf in
the saloon close 10 the stoves. We saw no one to
explain the Improvements in this over the locomotive
new in general use, but examination OF the work.
ing model, (Which of itself weighs $50 pounds, and
worth Sl0000 we discovered the following ar
rangernent OF the machinery.
The feed pipe to supply cold water passes to the
pump in the same manner that it does on the com
mon locomotive; but the pump itself Is situated IN
different positions il is placed upon the fire box, ev
IDENTIFY to prevent the water freezing the depth Of
winter, which it frequently does on the old plan
From the pump the cold water is carried up 10 the
top OF the boiler round the chimney, (,he chimney
being placed in the centre of the beer) cOncentrc
cylinder; the water is taken thence the inside and
brought in pipes through the fue (the latter at the
time being nearly fall of flame and smokey to the
boiler. The water passes INTO the boiler through a
ball valve placed inside OF each pipe which secures the
boiler.
By the ilme that the water, Carried round in this
way) reaches this boiler IT certainly must be heated
to the boiling point or at least 200 degrees. The
dome of the boiler that receives the steam before it
reaches the throttle valve is placed in the chimney
10 prevent the condensation of steam by cold be-
in the other locomotives the steam is continual
y condensng in cold weather account of the out
very often whilst the inside is heated TO lis or l20
degrees the temperature of the outside is less than
l06 degrees
We also noticed top apendage to the boiler which
is divided into two chambers the front chamber is
simply return iue for the fire and fame and the af
ter part is a most excellent arrangement it Is no
other than steam chamber, for the purpose Of sepa
rating the from the water, to enable the
engineer 10 work dry steam all the time instead OF
steam and water.
Another improvement struck us as being important;

tinct parts; the lower half of which is worked by
steam. and the upper half by hand; this latter me-
thod highly desirable in case OF an accident such as
the engine running cit the track or into snow drift
as in either case becomes necessary to put out the
fires instantly. II will be apparent even to those UNI
acquainted with the machinery OF a locomotive,
that when the engine stops the steam water pump
stops-but as the steam still is generated the pipes
would soon be melted if the fires were not put out
and in such this only be effected by the in
lection Of wafer through the medium Of the hand
pump.
There is a decided improvement also in the valve
governor; on the old system, (every one knows who
has travelled on a rail road, or seen q locomotive in
metion the three handles, the connecting rods, the
rocker levers the excentric hooks, and all the cross
shafts are flying about and are in rapid motion as
long the engine is moving This, Of course, causes
great friction and il has been calculated that 10
come this, &c and set ordinary locomotive in mo-
ton power is required equivalent to ten or twelve
horses
In the locomotive we are describing there but one
handle, in place Of three; and this one governs both
valves of the cylinder the motion, and starts
the engine. Again this plan model, when the
engine is in notion the handle connecting rods rock
er levers hooks &c. all az rest the fcrum of the
valve the wheels and piston rods being all that have
separate motion. There is in short, nothing what
in motion IN the upper part OF the engine. This
IS also highly important arrangement for we be-
heve IL is but a very short time since man was
knocked off the engine the Worcester rail road by
the Tying to and fro of the three handles which
govern the valves.
The last Improvement which we noticed but by no
the least is in the adjustment of the cylinder,
which IS movable. BY making use Of q movable
cylinder, the crank is worked, or rather the steam is
applied IN direct line, by which on usual sized en-
gne at least 1900 lbs Of power mast be gained over
the old engines and thus third Of the fuel can be
saved.
An objection has been raised to the employment, OF
movable cylinders, account Of the strain on the
suffing box but in this model, we observed that
two guide rods applied TO move the cylinder, aHs
these prevent any such strain. The whole msve-
mcnt, were pleased TO see simpliied BY means
of the movable cylinder; and thus we consider the
doubts OF scientific men, with whom this question has
long been a problem must be entirely set at rest.
