PAPER MAKING MAoH1NERY.
Some of the Machines Made by the
Pusey Il Jones Company.


With the utilization OF many new raw ma
terials in the paper manufacture during the
present generation, new improvements have
been made in the machinery used by paper
makers. There has been great increase in
the amount Of all kinds OF paper used-from
cheap postage and low priced books and
Newspapers but the competition of paper
makers has been close, and they have been
quick to adopt ana fertile IN suggesting i'm
provements in machinery, whereby the pro-
duct might be bettered or hand labor re-
duced. In this department OF the worlds
industry American paper makers, and manu-
facturers of improved machinery therefore,
now easily hold a leading position.
In the Scientific american of last week we
gave some particulars of the paper manu-
facture, as conducted by one OF the principal
houses iii that business and We herewith
| present illustrations OF many of the special
machines used IN the Transformation OF rags
| and other hbrous materials into paper, III
they have been improved and are now made
by the Pusey X Jones Company, Of Whining
| ton, Del.
In mentioning the several machines as they
| come in natural order iii the paper manufac-
ture, the first would be the rag cutter,
| machine which has been only few years
used instead Of cutting up the rags by hand.
This is solidly built machine, into which the
| rags are drawn from an apron by toothed
| cylinder, aud meet another rapidly revolving
| cylinder on which are knives that cut them
almost as would a pair OF shears. The
machine works very rapidly, and the bearings
| are adjustable, no that the shaft on which the
cutting cylinder runs can be always kept true
in its place without regard to the amount OF
wear it may have had.
The rotary boiler, to which the rags go
after cutting, busting, and asserting, lis
strongly made, the clampod covers shown in
dicating the openings through which the rags

boiler through the hollow trunnion on which
1t revoves. In order that this trunnion may
be entirely true, and the boiler perfectly cen
tered thereon, II il fixed in its place after the
boiler il finished, and then turned to the
exact size ana iinish thus avoiding any wab-
bling or uneven revolution OF the boiler in
operation. The occasional explosions OF these
boilers III paper mills have been the subject
OF various conjectures as to their cause M
the steam here could not naturally be OF
greater pressure than that of the generating
boiler whence 1t comes. The company explain
| these explosions as due TO the supply. in such
instances, OF superheated steam coming sud.

to advise their customers to use generating
boilers which cannot superheat the steam.
