Evening star. [volume] (Washington, D.C.) 1854-1972, 1881-07-16

Besides this. in all presses printing from types
direct, it is necessary to feed sheets through
twice in order to print both sides, and if folded
| they are still fed into another machine. The
| new press does this all at one operation feeds
| Itself, prints both sides at once and folds the
papers at the same timc-it is, in short an
| Automatic Machine. At the tt1se Of its pur-
chase the old Machine was regarded as fast
press. and, even at this day, fairly closed its
| record in ''blaZe of glory i'm printing nearly
sixty Thousand papers on the day of the at
tempted assassination of the President. But
it is not equal to a paper of large circulation
which must be printed and distributed i'm a
short time, and yet include up to the latest
moment all of the news Of the day.
THE SCOTT PRINTING AND FOLDING MACHINE.
1t had become evident for some time after
revolving printing presses had been in use, that
the only correct plan of constructing a faster
press was by having rotary and automatic
motion-as nearly automatic as possible-that is,
feed itself as fast it could print and fold the
papers as fast as it could deliver them. The
early machines which were invented to feed
from roll of paper were failures because of the
difficulty OF holding the type on small cylinders
though the seH-feeding was a step in the right
direction. The first practical web press was
! introduced by William A. Bullock in 1862. and
the second one ever made is now i'm use in the
! Government printing office. This machine cut
sheets from the web before printing them. and
transferred them from one impression cylinder
to another by means of grippers during the pro-
cess of printing. In 1868 the wel-known Walter
press. on which the London Times is now
printed was imported into this country This
machine. two OF which are in use in the Unit ed
States, cut the web of paper into sheets after
being printed, which was quite an Improvement.
But these machines, when first made. did not
fold; and since their introduction many attempts
have been made to construct machine which
would fold the sheets fast they are delivered
by the press and work automatically i'm cOmbina-
ton with it. In 1872 Walter Scott, of Chicago,
invented his web printing and folding machine.
to work in combination with web perfectng
presses. Although delayed for some time yet
he was the first to produce machine with one
set of folding devices throughout. which would
automatically fold the sheets as they came from
the printing press without reducing its speed
Since then he has made many improvements,
which are included In the press before U.s. The
marvellous success attending this machine is
being made by revolving creasers.
Mr.. Scott also introduced the pasting and cut
ting arrangement, he having been the first to
combine printing, cutting, FASTING and folding
machine, SO that, from roll of paper, perfect
copies OF newspaper are produced automati-
ca1y, with the leaves cut and pasted in book
form.
Several makers have constructed combined
printing and folding machines but none of
them seem to have the same success as Scott's
machine, probably owing to the fact that they
employ the old method of tapes and rollers with
vibrating creaSers. Some have even found if
necessary to employ two OF three sets of folding
devices to each press so as to get up fair rate
of speed.
The accompanying cut represents the new Scott
machine on which The STAR is now printed. II
was built by Messrs. C. Potter, jr.. g. Co.. New
York, under the personal supervision Of Mr..
Walter Scott, the inventor and embodies all the
latest improvements in that class os machine.
The following description will enable the reader
to form some idea of how The STAR is produced:
81 THE COMPOSING ROOM.
AS the types for each edition are set up in the
composing room they are assorted into pages
Each page is placed in a steel frame or chase y
laid upon handsome tables covered with brass,
which now supersede the old imposing stones
and the type is made fast by steel side-sticks'
presenting successive surfaces Of inclined planes
which are driven into their places by the applica-
ton of the screw and wrench. The "forms =
having been sent down by the elevator to the
sTEREOTYPING DEPARTMENT.,
In the machinery room, are taken in hand By
the stereotyper, who has previously made ready
o couple Of sheets of papier mache by pasting
them together to the thickness Of cardboard.
The face Of the type is slightly oiled with brush
to prevent the paper from adhering, and the
prepared material is laid on the face Of the type
! and beaten briskly with hard bristie brushes.
The form with the ''matrix" into which the
papia nsache has now been manipulated il slid
on to a steam drying table. at whose end - .
'platen" shaped like letter copying press; the
form is pushed under the platen, theser
turned down closely and the s'matrix" Il dried
