| at the Pan-American exhibition at Buffalo
| this year
committee consisting of Assistant
| Commissioner Chamberlin, Chief Clerk
| Shepard and Examiner Witherspoon, was
| appointed last summer to prepare the pat
| ent office exhibit, and has been busy on the
matter since that time.
| Speaking of the result of its labors. Mr..
| Chamberlain said today:
| 1.-The Constitution provides that in order
| to promote the advancement of science and
| the useful arts there may be secured to
| inventors or discorevers for limited times
! the exclusive rights to their inventions or
| discoveries, and the purpose Of the patent
| office exhibit, is to convey to the public the
importance of our patent system. which
has grown up under laws made in accord
| ance with this provision.
I'm order to do this, some Of the latest
| advances in the various arts and sciences
| have been selected for Illustration, and the
exhibit a whole will be made up of
working machines belonging to the selected
| classes of invention, and Of diagrams and
| explanatory cards briefly explaining the
| salient principles involved in each.
Heretofore, at various expositions, 1T mas
| been customary to show large number OF
| models. illustrating various arts; but owing
| to the fact that such models are now more

actual operation, this year 1t was decided
| to make the radical change of operating as
many actual machines as possible so that
| from these the public could realize the
great additions to its comfort which 1t Is
receiving at the hands of the inventors of
| this country.
Machines That Are Wonders.
Talking machines might be cited as one
| Of the arts selected" continued Mr.. Cham
berlin, land their exhibition will involve sec
tional models showing on an enlarged scale
| the sound waves constituting articuate
| speech, and full-sized machines in actual
operation. Diagrams showing the difference
between musical waves in the air and those
of articulate speech will be provided, and
cards explaining briefly the main points
involved will be employed in connection
! Herewith. From the whole a layman In
| a few minutes will be able to get an &C
eurate idea of just how and why graph
ophoEe, a gramophone or telephone re-
| produces articulate speech.
| THE photographic transmission of mes
! sages is another art selected which Will De
| illustrated by two working machines. THESE
instruments in practice enable man In
Washington to write check, message or a
! letter and have 1t faithfully reproduced at
| a distant city in his own handwriting, on a
| similar machine. At the exposition both
| the sending and receiving machines will be
near each other and connected by miles or
wire. The visitor may write what he
pleases with the pencil Of one machine and
watch the pencil of the other automa tically
copy his own handwriting, through electric
currents sent along the wires connecting the
two instruments. Suitable explanations OF
| how and why it is operated will be supplied.
Electrical Reproduction of Pictures.
| IN order to give the public an idea of
! how pictures may be electrically reproduced
| at distant points," Mr.. Chamberlin went
on, machines for accomplishing this pur-
! pose will be likewise connected by miles OF
| wire and photographs placed In one will be
1 reproduced on the other, so that the whole
| operation can be taken in at once.

'The earliest and latest Improvements in

| suitable operating models, and In the art
| Of printing the linotype and monotype ma
| chimes will be operated on the spot giving
| the public a comprehensive Idea OF what
they mean to our great daily papers.
"a complete X-ray outfit will be in operas

sulphite process. will be illustrated by be-

! Mfr Chamberlin In conclusion, Inventors
would not spend their time and money to
produce the various improvements which
are the very basis of our progress and
