The Nav and Novel in Mechanism Seen in
Practical Operation at the Great Phil
adelphia Trade Show-Three
Kinds of Power From ,
One Plant.
Philadelphia, Nov. THE moving
machinery at the National Export ex-
position has become one of the chief at
fractions of the exhibition, affording as
it does an infinite variety of amuse-
ment, diversion and information to the
increasing crowds at the big trade
show. The power for this great variety
of animated exhibits is supplied by
electrical transmission, by shafting and
by steam.
A visit to the great power house
where the immense steam engines and
electrical dynamos and machinery are
whirling day and night is a good
starting point from which to take In
the other mechanical displays in the
various buildings. The steam plant
here has an aggregate capacity Of H.
900 horse power. The main building Is
supplied with steam and with gas for
power and heating, and electricity for
power The operation of all these sys-
TENS Is in full sight, with special ar
rangements to enable the visitor TO
examine every possible detail.
In all there are perhaps $50 exhibits
supplied with power. These constitute
what is known as the moving ex-
hibits of the exposition. 1t is impos-
sible to examine all these interesting
features of the exposition in detail, or
even to summarize them. A glance at a
few will serve to indicate the interest
and importance of the many. The COM
plete making of a high grade shoe by
machinery is shown in one extensive
exhibit, in detail. Over in another aisle
is most interesting piece OF machin-
cry which congresses 1000 pounds OF
scrap tin, which in its loose state would
fill several hogsheads, into bale IL
inches In diameter and "a inches long.
This machine, which is in complete
operation nearly all the time, was
originally intended for cotton COM
presser, but it has gone far beyond
that and is a success in COMPRISING
into the smallest possible space old tin
Gas has been SEEM, or to use the VEN
acular "any old thing" which needs to
be put into a little bale for the pur-
pose of easy shipment. For instance.
it congresses $50 pounds Of hay into
a little bundle 10 inches high and Is
inches in diameter
Near this wonderful enemy to Tex
pansion" are the busy and tuneful
ribbon looms, where colors are woven
with such marvellous dexterity into
the fabrics best beloved of women.
These wonderful machines when In
motion, which is almost all the time,
are surrounded by an eager and inter-
ested throng. One of the many OF
them makes a series of ribons with ten
plaids and as many colors without the
intervention of single human hand,
and another weaves a beautiful piece
of jacquard work. picture souvenir of
the exposition, with equal mechanical
skill All of these silk looms are so
arranged as to show how simple, after
all, is the mechanical device which
works such wonders.
The shuttles of a number of other
textile machines hum merrily nearby,
among the most interesting being
those which fabricate prettily pictured
bath towels and materials for bathing
robes, with interviewer artistic designs.
OF somewhat different character in this
moving school of mechanical art ex-
hibits are those new wonders of mod
ern printing, the type setting machines.
Not only is the famous linotype ma
chine shown in actual operation by two
or three newspaper establishments. but
the simplex type setter can be seen
working with equal ease and with
astonishing results. In the case of the
linotype machine the matter is set up
in the shape of single line of type, in
the other actual type is set up and ar
ranged mechanically. In each process
keyboard, like that of a typewriter, Is
used. The study Of the two by COM
parison in actual moving operation is
most interesting. Nothing is more In
teresting than the working of the
numerous presses and dyes-solid ma
chinery weighing from 500 pounds to
5000 pounds doing as delicate work
in the making of metal Impressions
almost as that of the steel engraver
himself
OF a somewhat more frivolous. al
though of an equally interesting
character, is the work of the buZzing
artistic saw, or of infinite varieties of
them. The results which they can work
out of cube of two inches and half
is something which makes the young
sters stare, perfectly dumfounds his
mother or his aunt and often quite
astonishes the head of the family him
self Almost In a twinkle of an eye one
of these cubes is traversed by the saw
in curious and fantastic turns, and
there is produced, in addition to per-
feet table, 20 other devices, all of
which can be instantly taken apart
but only with infinite labor and pains
restored to their original shape. These
little products of the saw are childrens
puzzles, but the industrial possibili-
ties and actualities of the devices are
shown in many practical, useful and
valuable devices.
While these wonderful saws buzz on
one side of the aisle the visitor is at
which comes from the industrious
movement of a mechanical oscillator,
which is an ingenious device to take
out of wheat all the -four there is In it.
The machinery of the hat factory,
which presses the felt into the head
moulds and irons the hats and does
OLuST CuTlOuS things III the making OIL
a hat, is another important exhibit.
Nearly all of the wonder of hat max
ing-we are not speaking of the milli-
ner-is taken away after an Inspection
of these mechanical devices. The ma
chinery of leather making, its polish
ing and the various methods of its
establishment, keep large number of
unique machines busy, and also keeps
those in charge of them full of business
in answering curious questions. One
turns from this exhibit to hear nearby
the lively crack of bursting popcorn
and, turning, finds here some busy ma
chinery engaged In the apparently
simple process Of manufacturing COM
monplace popcorn balls. Nearby is a
coffee hulling machine and not far
away a section of sawmill In opera
ton.
The ponderous machinery which can
crush granite rock as easy as one
can break an egg shell in the hand Is
In operation in the implement building,
where are many other interesting NOV
ing things.
