Models That VIII Delight the Eye of the
Inventor and Mechanic

Models That VIII Delight the Eye of the
Inventor and Mechanic.
The patent office at Washington is pre-
pairing one of the most interesting exhibits
tina: viii have a place in the Worlds fair.
Patent Commissioner Simonds has been in
correspondence with some of the leading
manufacturers of the country, and they
have promised some expensive working
models OF their improved machines. One
of these Will be Hoe perfecting press,
about five feet long, which will be in actual
operation throughout the fair. The Strik
ing feature of the exhibit will be the fact
that il will not only show models from the
first institution OF the patent office to the
present time but will, in many cases, go
back OF the establishment of the patent Of
fee in 1896. and even back of the record of
patents by the state and war departments
before the patent Office was established.
The Very First steam Engine.
There will be copy of the rotary steam
engine invented by Hero centuries ago, a
copy of the press which Franklin used and
many other models of rare historic interest,
The Eli Whitney cotton gin. on which
patent was granted by the state depart
ment in 1774. viii be exhibited and

original model, and the first machine gun,
patented by John w. Cochran in 1894 In
every department the effort will be made to
trace the gradual process of invention from
the dawn of a fruitful idea down to the
present day.
Progress of Electrical Invention.
The wonderful progress of electrical in
vention will be fully shown, all sorts of
weaving and knitting machines, steam
gines, paper machinery and the most mod
ern designs for small arms and cannon.
Those models are in many cases the perfec-
ton of delicate mechanism. and their bur-
nished steel and brass and nickel make
them as attractive to the eye as anything
that will be on exhibition. The exhibition
made by the patent bureau will be SO re-
markable an epitome of the progress of
invention in the United States that Com
missioner Simonds will probably ask au-
thority from congress to put the record OF
it in some permanent form.
Symonds' Proposed Record.
He will have some of the models photo
graphed and will lay them before the APP
propriate committee of congress sam
pies of what he would like to do. If the
committee is disposed to provide for per
manen, record he will suggest an appro-
prii.t ~ of few thousand dollars for pho
tographing all the models and having the
photographs engraved and printed, with
proper descriptive text, in the government
printing office. There will be about 2, 500
models exhibited. Nearly 1900 of them
have already been selected.
Two Immense Search Lights.
Two big search light, which will be used
to illiumine the grounds next summer,
have arrived ON the Worlds fair grounds
and will probably be used for the dedicatory
exercises These great lamps weigh re-
spectively 1900 and 1,30O pounds, with
diameters of four and three feet. The
larger one will be placed on the roof of the
manufactures building. and will, it is
said, light up the Van Buren, street station,
seven miles away, WIN the intervening
space. The other will IL i.Io,-nted on the
cupula of the transportation building and
will shed light the Illinois Central
tracks to the south and west.
