COMPLETE SPECIFICATION.
Improvements in Apparatus for use in the Manufacture of
Wood-wool.
We,
OLE EVENSTAD, Mill Owner, and OLAUS SENSTAD, Mill Manager, both of
Rasten Storelvedalen, in the Kingdom of Norway, 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:-
Our invention relates to the manufacture of wood-wool, and it comprises improved
means or apparatus for splitting or cutting the shavings into longitudinal strips
immediately after they are cut from the log, the said apparatus being specially
intended for use in combination with the machine for making wood-wool described
in the Specification of former Letters Patent granted to us dated March 20,
A.D. 1888, No. 4296, which machine only works satisfactorily with shavings cut by
a smoothing-plane while the improved apparatus will enable the said machine to
work with shavings cut by a jack-plane.
-According to our invention we place adjacent to the edge of the cutting-iron or
bit, a series of parallel sharp edges or ribs against which the shaving will impinge
as they leave the cutting-iron. These ribs are either filed in the edge of the break-
iron commonly used in planc-irons or formed on a separate plate arranged between
the cutting-iron and the break-iron.
To enable our invention to be fully understood we will describe the same with
reference to the accompanying drawings, in which
Figures 1 and 2 are an elevation and edge view respectively of a plane-iron having
splitting ribs formed on the edge of the break-iron.
Figures 3 and 4 are views similar to figures 1 and 2 respectively of a plane-iron
having splitting ribs formed on a separate plate between the cutting-iron and break-
iron, and
Figures 5 and 6 are similar views illustrating a modification of the latter
arrangement.
Similar letters of reference indicate corresponding parts in the several figures.
a indicates the cutting-iron, a' the break-iron secured thereto by screws passing
through slots c in the iron a, and d the ribs. As shown in Figures 1 and 2 these ribs
are formed along the edge of the break iron and are substantially at right angles to
the edge of the cutting-iron, while, as shown in Figures 3 and 4 the ribs d are repre-
sented as being formed in the edge of a plate e adjustably fastened to the break-iron
by screws and occupying a position between the said break-iron and the cutting
iron.
In the modification of our invention shown in figures 5 and 6 the ribs d are repre-
sented as formed of steel springs placed parallel to each other and having sharp edges
placed adjacent to the edge of the cutting iron. These steel springs are held in a
clip g which is adjustably fastened between the cutting and break irons by screws f
in the same manner as the plate e in order to maintain the steel springs in their proper
positions along the edge of the cutting-iron grooves are formed in the underside of the
break-iron in which grooves the springs lie.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is :-
(1.) In apparatus for the manufacture of wood-wool, the arrangement in combination

page_text: with the plane-iron of a series of parallel sharp ribs or edges against which the shavings
impinge immediately after being cut from the log, the said ribs being formed either on
the break-iron or separate therefrom, substantially as described.
(2.) The manufacture and use of planing-irons having splitting ribs in connection
therewith substantially as herein before described and illustrated in the accompanying
drawing.
