The Science Of Bsilreadins-H Hsw tsPfe-
vent any Switch Accident.

When railroad is built from point to point,
1t is one continuous unbroken iron way with the ex
ception OF those portions controlled by switches The
switch breaks road. and q switch is necessary.
the problem has always been how to obtain its advan
tages without its dangers. As 1t now IT, the switch Is

one train off track and BY neglect. absence
Of mind forget to turn the iron rod back to nd the
next train whirling and tumbng down a ravine- Prom
what we have seen of railroad disasters and their
causes it is very certain that IL by any system the
switch can be established without breaking the road and
placing every train at the mercy Of one abe bothered
man. will wonderfully lessen the number of accidents.
Mr. Wharton of Philadelphia thinks he has solved this
problem. model OF his invention may be seen at the
American Institute Fair. while 1t IL really in practical
operation on the Harlem Railroad near Ftsth-st In
this city. The main advantage Of Mr.. Wharon's plan
is that the two rails Of the main track continuous
and unbroken. without any movable rails or moving
switches. second point Is that his switch answers
every purpose and makes itself right II the subordn
ate is careless and neglects his business the switch will
attend to ITSELF We best elaborate its advantages
by giving something of a technical explanation. The
car wheels steam railways are over two inches wider
upon their surface than the rail upon which they
Consequently the wheels extend over and beyond the
outside OF the rail for that distance This extra width
oftwo inches more Is used by Mr.. Wharton for the
purpose of switching the off the main line in this
way. Another rail is arranged with regard to the
main rail that IL can be moved at will sideways
against the outside OF the main rail- and 1t ia at first Of
tho same hight but gradually inclnes upward. so that
when placed in position to act as switch, the cars
advance the wheels upon that side gradually and
gently elevated above the main rail little more than
the hight of the fange. bearing Only on tho switch
rail- and being entirely free from the control OF the
main rail- long stationary guard rail having quietly
drawn the wheels to that side they have OF course the
whole OF their extra width OF tread extending boyoad
the main rail and bearing upon the switch rail outside
Of it AT the time this stationary guard rail has
drawn the wheels upon the other side little away from
the main rail Of that side that their 1anges in

which lies close up against the inside OF that main rail-
and they can not therefore ever touch strike against
the point itself These two switch rails, together with
another acting as movable guard rail- securely
