four feet Jong, extending from that part 
of the web which is next the vat, ia the 
direction of the line of motion. Between, 
and in contact, as well with the under- 
edges of these pieces, as with the upper 
surface of the web, are placed two end- 
legs straps of leather gf a width corre- 
sponding to the thickness of the pieces; 
which cause them to revolve upon pullies 
with a velocity exactly equal to the velo- 
city of the revolving web. ‘There are 
similar pieces and straps in contact with 
the under surface of the web, and exactly 
opposite to those upon the-upper su: face ; 
so that the webis pressed between the 
upper and under straps and pieces, and 
the liquid pulp is thereby prevented from 
running off towards the sides. These 
pieces and their straps are called dick/es, 
Near that part of the web upon which, 
the pulp falls from the inclined plane, 
and between it.and the vat, is placed a 
flap of oiled silk, or other fiexible mate- . 
rial; one edge of which rests upon the 
web, the other being fastened to a_piece 
of wood laid across the surface of the 
web, but not touching it; the length of 
the said piece corresponding to the width 
between, and being supported at each 
end by the dickles. The flap of oiled 
silk is to prevent the pulp from running 
back towards the vat. Between the two 
principal or extreme rollers upon which 
the web revoives, and about two feet and 
a half from one of them, and between 
that and the vat, are placed two other 
rollers, or cylinders, one above the other; 
and they cause the upper part of the web, 
with the paper forming thereon, to pass 
between them for the purpose of pressing 
out the water; and from this use of them, 
they ave called the first or wet-press cy- 
Heiden: or rollers. In order to guard the 
pulp, which, before passing between the 
cylinders, is yet ina soft state, from being 
dislodged or otherwise injured by the 
upper roller, or cylinder, coming imme- 
diately in contact with it; they use an- 
other revolving web of wove wire, or 
other fit uraterial, which in this case may 
be of felting, of the same width as the 
one above-mentioned, but not so long. 
To distinguish which last-mentioned web, 
from the other web before-mentioned, 
_ they call the fivst-mentioned web by the 
name of the under web, and the web now 
deseribing the upper web: the bottom 
part of the said upper web, passes he- 
tween the two cylinders, so tiat its under 
surface falls upon the surface of the pulp, 
or paper, and defends i from the action

of the upper cylinder. ‘This:upper web 
is kept extended by, and made to revolve. , . 
upon two rollers, placed ove on each 
side of the wet, press cylinder, and at a 
convenient heishtabove them. The wet 
press cylinders, are provided with a com- 
pressing apparatas at each end, to give 
the necessary pressure to the paper. It 
is evident, then, that, if motion is given in 
the proper direction to the wet press 
cylinders, having both the webs thus com- 
pressed between them, such webs will be 
drawn along by them, and caused to re- 
volve upon their respective rollers, and 
that as long as these webs continue so to 
revolve, and the pulp continues supplied 
aud running upon the surface of the une 
der web, so long wil) the machiie con- 
tinue making a sheet of paper of conti- 
nually increasing length, But as the 
paper, after having passed between the 
first press cylinders, has not. obtained 
such a degree of consistency and strength, 
as to allow of its being removed trom the 
machine, and cut into sheets, and laid in 
packs; they therefore cause it to pass 
through a second pair of pressing cylin- 
ders, whicly are denominated the second 
or dry press, where it receives such a 
further degree of pressure aud consequent 
strength, as to fit it for all the subsequent 
operations necessary to finishing it for 
market. The paper, after it has passed 
the first press, and arrived at theextreme 
roller upon which the, web revolves, is 
detached from the surface of the web, 
and.deposited upon the revolving felting, 
and with it made to pass between the 
second press cylinders. The paper is 
then collected and wound upon reels, or 
rollers, which ave successively removed 
and others applied, as they become char- 
ged or filled with paper. The long sheets 
of paper thus obtained are, by a subse- 
quent process, cut into others of the re- 
quired dimensions. 
We now proceed. to describe, nearly 
in the words of the patentees, the means 
used for subdividing or cutting the long 
sheets of paper into others, or smaller ones 
of the required dimensions: “ We (say 
they) construct a wooden frame or table, 
of a convenient height, its length is detes- 
mined by the dimensions of the sheets 
of paper into which the long sheets, upon 
the reels or rollers, are to be subdivided 
or cut, and, its width is made somewhat. 
more than the widest sheet which cun be 
made by the machine, by which the 
paper was fotmed. ‘Tie reel, or voller,
