Improvements in the Construction of Wooden Rollers to be Used in
the Manufacture of Paper.
I, ADOLF WIEDWALD, of Radewell, near Halle a/S., in the German Empire,
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:-
The invention, the subject of the present application, has reference to the con-
struction of wooden rollers, for use in the manufacture of paper; these wooden
rollers being cylindrical in cross section, and centrally provided with a square bore.
The object of the present invention is to more firmly and rigidly connect the
individual parts constituting the rollers, which are otherwise constructed and
secured together in the usual way. For this purpose I employ a.clamp at the two
extremities which are driven into two adjacent parts of the roller.
The invention is illustrated in the annexed drawing in which—
Figure 1 is a cross section, and
Figure 2 a front elevation of the improved wooden roller.
Figure 3 illustrates a clamping device separate from the roller; but the inven-
tion is not limited to this particular one, as any other suitable clamp may be
employed if necessary.
The wooden roller consists of four parts a, a, b, and b. The external shape of
these parts is somewhat that of a sector of a circle in cross section, the internal
face being plane. These four parts are provided at their edges with grooves and
projections; or they may be dove-tailed; so that they can be secured together in
the usual way, so as to form a smooth cylindrical outside surface. After the
parts a, a, b, and bare fitted and glued together, four or more of the clamping
devices e are entered into the four parts in such a way that each clamp serves for
securing and drawing together two adjacent parts. The clamps are in the form of
staples, having the two pointed arms f f¹, g being the centre part or bridge of the
device.
It is obvious that the wooden rollers may be of any required dimensions. If
the rollers are of extraordinarily large size, auxiliary clamps may be employed,
which are driven into the outside surface of the roller in such a way to connect
two adjacent parts by one clamp as shown in Figure 2. Other suitable clamping
devices, which enable the securing together of two adjacent parts, may be employed,
in lieu of those illustrated.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is:
The herein described improved wooden roller for the purpose Specified, namely.

of a plurality of parts, connected together (in addition to the usual means) by
clamping devices which secure together firmly the adjacent parts; as set forth.
