An Improved Beating Engine for Paper Stock.
'We, THOMAS CADWALADER CADWGAN, of Anderson, in the County of
Madison, and State of Indiana, United States of America, Machinist, and
THE O. S. KELLY Co. of Springfield, in the County of Clark and State of Ohio,
United States of America, a Corporation 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 and accompanying
drawings
Our invention relates to improvements in devices for disintegrating stock, for
paper making.
The object of our invention is to provide an improved form of device by which
the operation of disintegration shall be a practically continuous one, the stock
being fed into one end and discharged from the other in a sufficiently disintegrated
and reduced condition.
We attain these objects by the constructions shown in the accompanying
drawings, in which-
Fig. 1. is an elevation of a machine embodying our invention, with one. of the
side plates removed.
Fig. 2 is a plan view of the same shown partly broken.away.
Fig. 3 is a detail in section of the adjusting devices.
Figs. 4 and 5 are details showing the. construction of the beaters or disinte-
grating cylinders.
Fig. 6 is a detail view of the shower pipe used in connection therewith.
Fig. 7 is a detail view of the cylinder bearing.
Like parts are represented by similar letters of reference throughout the several
views.
In the said drawings, a a represents a main casing, which consists of suitable
side. plates. a having slotted openings a² into which are fitted bearing blocks a³, for
supporting the journals of the cylinders bb12; these cylinders 6662 are enclosed
within the outer casing a; a suitable cover a, which fits between the side plates a¹ a',
being adapted to close the top of said casing. The bottom of said casing consists
essentially of a sliding bed plate c, which rests on suitable flanges or ways. a,
formed on
the inside of said side plates a¹ below the cylinders. The
cylinders 2 are each formed on the outer periphery with a series of ribs b³,
which operate in conjunction with opposing serrated concave plates c¹² c³. These
concaves are preferably formed of hard metal, preferably of steel, and are
removably seated in the bed plate c.
Each of the cylinders is preferably. constructed on its periphery of a
series of flat steel bars or plates 6, which are supported at each end, and if desired
at suitable intervals, by supporting heads, having central openings 6 to fit on
supporting shafts, which form the journals for said rollers. The heads 6' are
provided with peripheral guides 68, into which the bars or plates 6 are seated. Each
bar is further provided at each end with a notched opening 6, the supporting head
being similarly notched out, as shown at 60 (see Fig. 5). When the bars are in
place on the cylinder a retaining ring is driven into the notches thus formed
and thus retains all the plates, and bars. securely in position. on the supporting
heads so as to form a ribbed or serrated cylinder. The spaces or interstices

page_text: between the ribs or plates are then filled up, preferably with wooden blocks or
strips which are driven firmly between said plates or bars so as to stand at a
suitable distance below the outer peripheries of said plates, thus completely closing
the outer periphery of the cylinder, but leaving the ribs or plates projecting
sufficiently to form a disintegrating surface with the concave plates. Each of the
cylinders are similarly formed, but the plates or bars in each succeeding cylinder
are placed closer together so as to form a disintegrating surface of finer dress, the
concaves being similarly formed.
The bed plate c closes the entire bottom of the outer casing, except at the
discharge end thereof, where an opening d, is left, over which extends a screen d',
which bridges said opening and extends from the bed plate to the discharge
opening e¹.
The top or cover a is preferably formed with curved portions as, concentric to
the cylinders b₁₂, and at the point where these curved surfaces join, and
immediately over the space between the cylinders, the cover is provided with a
laterally extending opening a', which we term the shower pipe, and which is
perforated with a series of openings a throughout its length. A water pipe a
communicates with each of these shower pipes and when in operation showers
down on the stock between the respective cylinders so as to wash the stock from
one to the other of said cylinders and assist in the disintegration.
Means are provided for adjusting the bed plate c longitudinally on the ways or
flanges a³, which are inclined. The concave plates c¹ c2 c are also formed higher
at one side than at the other to correspond to the inclination of the bed plate.
As the bed plate, therefore, is moved up or down on the ways, the distance
between the outer periphery of the cylinder and the concaves is adjusted. This
adjustment we preferably accomplish by means of a wedge-shaped piece, which
extends from side to side of the casing, passing through suitable openings f¹ in the
bed plate so as to bear against the same on one side while the opposite side bears
against the side plate a' of the frame. By moving the wedge in or out through
the side plates, the bed plate is moved longitudinally on its ways or flanges.
In
An adjusting nut f³, operating on a suitable screw-threaded stud f³, is provided
for moving the wedge-shaped piece in and out; said adjusting nut being formed
in the nature of a sleeve which fits in a slotted opening in said wedge-shaped
piece, with shoulders on the opposite sides thereof so that as it is turned in either
direction on the screwthreaded stud f³, the wedge is correspondingly moved.
operation the stock to be operated on is admitted with a quantity of water through
the opening e and comes in contact with the first cylinder b, and is carried thereby
down along the bed plate between the cylinder and the concave; the cylinder
being revolved by any suitable means for this purpose. It should be stated here
that the cylinders in successive order are revolved at an increased speed so that
the stock is fed to the slower and coarser cylinder and passes from thence to the finer
and higher speed cylinder, thus forming a gradual reduction of the stock, which is
carried from one to the other partly by gravity and partly by the actions of the
cylinders assisted by the water which is showered in from the shower pipes between
the respective cylinders.
After passing the last cylinder and between it and its concave, the stock, ascends
along the screen d' to the discharge opening e', where it is separated from the
water used in the disintegration and is ready for such other treatment as is
necessary.
We have shown in the drawings three cylinders and three concaves. It is obvious
that any number may be employed, though this is the preferable construction and
generally found to answer its purpose.
It perhaps should be stated that the bearing blocks a³, supported in the slotted
openings, permit an upward movement of the respective cylinders in the event that
any foreign substance should enter between the same and the concaves. 1f desired
springs may be employed for holding the cylinders to their work, but ordinarily
the weight of said cylinders will be found sufficient for this purpose.

page_text: Means are also provided for adjusting each cylinder independent of the others.
This is preferably accomplished by means of set screws y arranged in the bottom
of each slotted opening and on which the bearing blocks rest. This independent
adjustment of the rollers is desirable so that the proper degree of fineness may be
secured for each successive operation. It is further useful in the event that a new
concave is placed in the bed plate, in which case its roller is adjusted to suit. The
adjustment of the bed plate, it will be understood, adjusts all the concaves uniformly
while the set screw serve to adjust each cylinder independent.
It is obvious that the devices herein described may be modified in the various
mechanical constructions. We do not therefore limit ourselves to the exact
constructions shown and described.
Having now particularly described and ascertained the nature of our said inven--
tion, and in what manner the same is to be performed, we declare that what we
