Notes of the Railway Men.
The European delegates are manufacturing
particular interest in the operative exhib-
Its Of the latest types of electric traction
systems in the big Westinghouse pavilion,
which presents in an attractive and orderly
arrangement the most remarkable COM
Dlnation of Westinghouse products ever
brought together under one roof. The
westinghouse exhibits are all notable for
their feature of thorough operative DEM
onstration, and the traction exhibits are
remarkable as the first complete operative
display of both direct current and alternat-
ing current motor and control equipments
ever made at an exposition. The Westing-
mouse alternating current railway system Is
already in commercial operation in Amer
lea over the lines of the Indianapolis and
Cincinnati Traction Company between In
dianapolis and Rushville, Ind, a distance
or forty miles, which is soon to be extended
passenger and freight service between the
two cities, and ten other roads now in
course of construction will be equipped with
a total of 21S motors of an aggregate capac-
lty OF 15,435 horse power The Swedish
government recently received the first
Westinghouse single-phase locomotive to
be sent to Europe, for use in experimental
economy tests of alternating current trac-
ton as a substitute for steam locomotfon
The operating exhibit of the Westing-
house direct-current multiple control sys-
tenn is of peculiar interest not only because
or the various new features embodied in
the design of the master controller the re-
verser, the unit-switch group and other i'm
portant details of the control apparatus,
but also In that the truck in operation. one
soon to be placed in service on the Long
Island railroad, is probably the heaviest
type constructed to date. the total weight,
exclusive of the motors, being 13, $50
pounds. The control apparatus includes
the new rectangular unit-switch group,
IN which every switch is circuit breaker,
and the bridging" arrangement of motor
circuits which permits change from Sc
ries to multiple operation without opening
the circuit. The truck is equipped with
two Westinghouse type No. lib motors,
each of 200 horse power capacity. slight
modification of type No. Sc in use on the
subway of the marlborough Company
in New York.
The Chicago Pneumatic Tool crowd al
ways attracts attention even when 1t has
no exhibit, but the combination of the ex-
hibit of machinery and the exhibit of men
which this company is accustomed to make
at convention, and which it is making
on large scale at Washington is very
impressive. Its booth on the exhibit
ton grounds, near street. is filled with
large assortment of machinery, most of
which was kept in constant operation yes
terday.
The two separate exhibits of the Yale &
TQEpe Ma pnfa curing Com in the ma In
building are well worth inspection. At one
booth is shown complete line of Yale
locks builders hardware. padlocks and
door checks. The door checks are of the
Blount construction, and have several fea-
lures which make them specially suitable for
general railway service in stations and on
coaches. The other exhibit contains a line
of Yale & Towne chain blocks and their
new electric hoist. The Triplex chain block
is now so well known as to render unnec-
essary detailed description, but the prac-
teal method of showing the saving in
power and time made by this block is COM
paratively novel and interesting.
The Adams & Westlake booth, with it's
gilded dome, which for several years has
occupied a conspicuous place at the ex-
hibits at the mechanical conventions in
June. has much better opportunity to
display its architectural beauties in Monu-
ment Park than it has ever had heretofore.
1t is a fine exhibit and deserves the at
tention that it receives.
