COMPLETE SPECIFICATION.
Improvements in Paper Making Machines.
1, HORACE AUGUSTUS MOSES, of 9 Elm Street, in Mittineague, in the Town
of West Springfield, County of Hampden and State of Massachusetts, United
States of America, Manufacturer, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
This invention relates to paper making machinery, and has for its object the
production of several strips of paper on a common wire cloth, cach strip having
an edge resembling that of hand-made paper, or as it is called "deckle-edged
paper:
And the invention consists in certain peculiar constructions and arrangements of
deckle-straps and suction boxes and other accessory parts, ali as hereinafter fully
described and claimed.
In the drawings forming part of this specification,—
Figure is a plan view of a portion of the frame of a Fourdrinier paper
machine showing a portion of the wire and the arrangement of the deckle-straps
thereon, and one end of the suction-box in section.
Figure 2 is a sectional view of the wire and suction boxes and slices on line 2-2,
Figure 1.
Figure 3 is a longitudinal section of a suction-box with the partitions removed.
Figure 4 is an enlarged cross section of one of the suction box partitions on
line 3-3, Figure 2..
Figure 5 is a front view of one of the nuts on the suction-box partitions showing
in section the adjusting rod therein.
Figure 6 is a detail view showing the relation of the apron and breast roll to the
deckles and other parts.
In the drawings, A is the frame of the paper machine; B, is the endless wire ;
C represents the deckle-straps; D, D', the suction boxes having the partitions E,
therein, and M, are the slices between the deckle-straps.
The deckles are applied to the wire in very much the same manner as in the
ordinary Fourdrinier machine.
A shaft. F, running in bearings on each side of the frame in a position at right
angles to the line of movement of the deckle-straps carries the grooved pulleys F',
over which the deckle-straps run, and whereby one extremity of said straps is
supported.
On two other shafts, G and H, parallel to said shaft F, supported on each side
of the frame A, are supported the frames L, which carry the pulleys F2 and F³,
which support, respectively, the opposite end of the deckle-strap and the upper
portion of said strap between the two ends thereof.
Between the frames L, and attached thereto, near the forward ends of said
frames are the slices M, which are adjustable vertically and in a line transversely
to the line of movement of the deckle-straps.
The frames L, are made as shown in Figure 2, with a looped portion S, fitting
over the shaft H, and a hook-shaped end portion S', fitting over the shaft G.
Collars m, m, on shaft H, and n, n, on shaft G, are set up close to said frames L,
and secured thereon by set screws after the said frames have been placed in their

page_text: proper positions on said shafts G and H. This construction permits of the easy
removal and adjustment of said frames which is of great advantage in making the
changes incidental to changing the width of a web or in reducing or adding to the
number of webs to be made on the machine.
Attached to the forward end of the frames L, are the dams N, which surround
completely the ends of the deckle-straps and are attached to each side of the
frame L, and so arranged that their lower edges, shod with felt or similar material,
have a bearing on the wire of the machine, whereby any pulp is prevented from
getting under the deckle-straps.
These dams N, are made of metal and preferably of copper, and are secured by
screws to the ends of the frames L, as shown in Figure 2. The two dams on the
outside deckles are extended out to the edge of the wire.
The two suction boxes D, D¹, are placed as is customary in paper machines of
this class. The suction-box D, is of the usual construction and is provided with
the end partitions only. The second box D', however, is provided with the same
number of partitions as there are deckle-straps, and each partition is adjusted in
the box in a line centrally with the central line of the deckle-strap.
Each of said partitions is made considerably wider than the deckle-strap to the
end that as said several strips leave the straps, a portion of each edge of each strip
or the web of the paper shall overlap the edge of the partition, whereby said over-
lapping portion will not be subjected to the action of the suction from said box D';
the web passing on through the machine with an excess of water contained in its
edges, which has the effect of producing, when the paper is dry, the uneven surface
and ragged edge which characterizes hand-made paper.
It has been found in practice that the common manner of connecting the suction-
pipes of the pumps operating on the suction-boxes is inoperative where there are
more than two partitions in said box and to overcome this defect the suction-box
is made as shown in Figure 3, and in Figure 2, viz., with a longitudinal opening O,
made in the bottom of the box which is long enough to extend from the space
between the first two partitions in one end of the box.to the space between the
first two partitions in the opposite end of said suction-box whereby each of the
divisional spaces in the suction-box is submitted to the action of the suction pumps,
in the same manner as if the box were provided with only two partitions, as in
box D, shown in dotted lines in Figure 1; that is to say, every space between
the partitions is connected with a common air conduit, which conduit is connected
to a suction pump.
The suction boxes are made rectangular in cross section, as shown in Figure 2,
and the partitions E, therein so constructed as to be expansible within the box in
all directions, which construction is shown in Figure 4, and is such as is commonly
used in paper machines.
The various partitions are arranged in their respective places, the central one
being first put in place, by being passed into the box from each end and when in
place opposite the end of the deckle-strap secured there by means of a T-headed
wrench w, applied to the slotted nut u, on the sleeve P, forming part of the
partition E, whereby the side E', of the partition is moved towards the opposite
side E, forcing the rectangular rubber gasket outwardly against the inner walls of
the suction-box, making it tight. The partitions on each side of the central one
are next placed in position and then lastly, the outer ones. These latter partitions
have a wrench passed through them, the T-end of which engages the nut u, to
expand first one end and then the other of the two partitions each side of the center,
the stem of the wrench passing through a stuffing box to stop ingress of air. The
two partitions on each side of the central one are usually the ones that are shifted
and therefore are provided with the wrench w.
It will be seen that the construction and arrangement of the parts of a paper
machine herein described permit the adaption of the machine to the making of any
width of strips of paper, each edge of which has the rough hand-made paper edge
which is of great advantage as the strip can be made of just the width necessary

page_text: to fold once, on a line parallel with the rough edges so that said rough edges, when
folded into a note size, form the two outward edges of the sheet.
If desired, the same machine can be used for the production of strips of various
widths of paper at the same time.
.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
14
1. The suction box having a longitudinal opening O, in its bottom, and a
suction-pipe connected thereto, combined with the adjustable partitions, means
for expanding them in place, the deckles and the endless wire, substantially as
shown.
2. In a paper making machine, the combination with the moving endless wire
cloth, of three or more deckle-straps supported adjustably on suitable frames over
said wire cloth, dams attached to the forward ends of the frames supporting said
deckle-straps, and a suction-box divided into two or more compartments by
movable partitions, a common air conduit opening into all of the said compartments
and communicating with the suction pipe of a pump, whereby air is withdrawn
from said compartments, regardless of the position of the partitions between them,
substantially as set forth.
3. In a paper making machine in combination, the main frame thereof, the
deckle-frames thereon having the looped portions S and S', therein, for engagement
with the shafts G and H, supported on said main frame and collars on said shafts
for holding said frames in position on said shafts, and the dams N, secured to one
end of said deckle-frames, substantially as set forth.
