COMPLETE SPECIFICATION.
Improvements in Machinery employed in the Manufacture of
Wood Wool.
I, JAMES HENRY CHANNING MARTIN, of 224 Devonshire Road, Honor Oak
Park, in the County of Kent, Gentleman, 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 relates to improvements in machinery employed in the manufacture
of wood wool.
For this purpose I employ a feed trough fixed with its bottom at an inclination
from the horizontal and having its outlet end suitably inclined from the bottom of
the trough, say at an angle of about 45°, more or less; the wood is placed in such
trough on its edge and with its length across the same; the cutting knives work
against the inclined face of the feed trough and move to and fro in the direction of
the grain of the wood, but act to cut only in the downward stroke. The trough is
filled with the wood, and at or near its outlet end it has on the lower side thereof a

page_text: holding teeth, effectually hold the wood close up to the cutters. I feed the woode
forward by an intermittently worked screw acting on a fork or half nut projecting
from a pusher or follower hinged on a rod extending the length of the trough. By
these means, when the supply of wood in the trough has been nearly exhausted, the
pusher or follower is turned on its hinges so as to remove it from the trough,
the latter is again supplied with wood, the pusher or follower is slidden back on its
carrying rod to the rear end of the trough and is then turned down into gear with
.the screw.
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation, and Figure 2 a back or rear elevation, of
machinery constructed according to my invention for the manufacture of wood
wool.
Figure 3 is a side elevation partly in section of the feeding trough and parts
.connected therewith.
Figure 4 is a cross section drawn on the line 1-1 of Figure 3, looking in the
direction of the arrow.
Figure 5 is a front elevation of the feeding trough.
Figure 6 is a side elevation of the front part of the feeding trough.
Figures 7, 8, 9 are respectively a rear elevation, a plan, and a side elevation,
of the follower or pusher with its half nut and part of the feed screw.
Figure 10 is a cross section through the cutters and cutter blocks, and
Figures 11 and 12 are face views of parts of the cutters.
Figures 3 to 12 are drawn to larger scales than Figures 1 and 2.
In all the figures like parts are indicated by similar letters of reference.
a is the bed of the machine, b is the feed trough, the bottom of which is fixed
at an inclination from the horizontal, and whose outlet end is inclined
backwards from the bottom of the trough, say at an angle of 45°, more or
less; the wood c is placed in such trough bon its edge and with its length across
the same; the cutting knives d d work along the inclined face of the feed trough
and are moved to and fro, as hereinafter described, in the direction of the grain of
the wood but act to cut only in the downward or outward stroke.
The cutters d d are fixed to cutter blocks d' carried by a cutter slide d³ working
in slides fixed at the required angle with the machine bed and such cutter slide,
in moving to and fro, takes a bearing against guides d' so as to keep the said slide
rigidly in its proper course. The feed trough bis supplied with the wood and, at
or near its outlet end &, it has on the lower side a number of fixed holding teeth /*
in the form of scoring knives, so as to enter a slight distance into the wood as the
latter is successively forced up to the same. I also, at the upper side of the feed
trough, arrange a number of springs or weighted or spring arms to bear against
the wood and, in conbination with the holding teeth 12, effectually hold the wood
close up to the cutters. In practice I employ a series of springs 63 fixed at one end
to the inside of the trough, and having at the forward ends a number of holding
teeth of similar character to those marked on the opposite side of the
trough.
e is the feed screw, which receives an intermittent rotary motion, as hereinafter
described, and acts on a threaded fork or half nut projecting from the bottom of
the pusher or follower f, which latter is hinged with capability of travelling on a
rod extending the length of the trough. By these means when the supply of
wood in the trough has been nearly exhausted, the pusher or follower is, by

page_text: means of the handle ³, turned on its hinge so as to remove it from the trough,
the latter is again supplied with wood, the pusher or followerf is slidden back on
its carrying rod to the rear end of the trough, and is then turned down with its
fork or half nut fin gear with the feed screw e, when it again gives an inter-
mittently forward motion to the wood in the trough. By this arrangement of
feeding apparatus, I am enabled readily to re-charge the feed trough, thereby
saving considerable time as compared with arrangements hitherto in use.
The cutter slide d³ is connected by pin d with one end of a connecting rod d',
whose other end is attached to the crank pin fixed to the dise or wheel d' fixed
on the driving shaft g, by which means such cutter slide d³ receives a reciprocating
motion. The feed screw e has fixed on the rear end thereof, a ratchet wheel
which receives an intermittent rotary motion from the pawl e²; this pawl is carried
by a lever e, which is pin jointed to the outer end of the eccentric rod et operated
by the eccentric fixed on the driving shaft g. I do not however confine myself
to the precise means herein described of giving motion to the feed screw and
cutting knives.
It will be evident that the angle at which the feed trough is fixed may be
varied without departing from my invention, but that herein shown is found to act
well in facilitating the falling away of the wood wool from the blocks c and thus
avoiding clogging of the knives. By causing the cutters to work at an angle
with the sides of the wood blocks as herein shown and described, I am enabled to
cut the wood almost entirely into "wool," only a very small triangular shaped
piece of waste being left of each block.
said
Having now particularly described and ascertained the nature of my
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The peculiar arrangement and combination of parts, substantially as herein
shown and described and for the purpose stated.
2. In machinery employed in the manufacture of wood wool, the arrangement of
the cutters at an inclination with the sides of the wood blocks, substantially as
herein shown and described, and for the purpose stated.
3. In machinery employed in the manufacture of wood wool, the combination
with the feed trough, of fixed holding teeth on one side, and of springs or spring
arms provided or not with like holding teeth, for holding the wood firmly at the
outlet end of the feed trough, substantially as herein shown and described.
4. In machinery employed in the manufacture of wood wool, the peculiar con-
struction and arrangement of the feeding apparatus, substantially as herein shown
and described.
