We ARTHUR WILLIAM GLOVER and MATTHEW HENRY GLOVER both of Potterdale
Works, Dewsbury Road Leeds in the County of York, Engineers do hereby declare
the nature of this invention to be as follows:-
Our Invention relates to various improvements in the construction and arrange-
ment of machines for cutting (or splitting) wood into sticks, for the forming or
arranging of sticks into position, and for the feeding of sticks into bundling
machines, and for tying the same into bundles.
Our Invention consists :-
1° In a self acting feeding arrangement or motion for feeding forward inter-
mittently the wood to be cut, by means of feed rollers having their axes horizontal.
The rollers may be arranged either with fluted or other uneven surface, or with a
covering of composition, rubber or other flexible material, to avoid disfigurement of,
the wood.
2° In feeding forward the wood by means of a revolving table or circular trough
or series of troughs, arranged in a circle, into which the wood is filled, preferably
opposite to the knife or knives, and from which, after passing under the knives, it is
discharged before again reaching the filling place.
An uniform intermittent motion is given to this circular trough, actuated by ratchet,
excentric, or other suitable means, whereby the wood is fed forwards bodily at a
uniformly intermittent rate, and split into uniform strips, blocks, or sections as may
be desired.
3° In a feeding arrangement, consisting of two endless chains or belts, provided
with projecting plates or cross pieces, which act as propellors or form travelling
compartments, between which the wood is packed and carried forward horizontally
under the knives.
In all the above feeding arrangements special provision may be made for the
expansion of the troughs or trays, when the knives descend into the wood, expanding

page_text: and splitting the wood. By these provisions all wedging of the knives is obviated,
and the latter can follow the grain of the wood as in hand splitting, and the
sticks are allowed greater play after being split, thereby preventing jamming or
overcrowding.
4° In the arrangement and construction of the knives. When it is required to sub-
divide the wood into slabs, before cutting the slabs into sticks; we arrange several knives
longitudinally. These knives are placed parallel, but not in line with each other, the
first somewhat to one side and in advance of the second. Similarly the second is
somewhat to one side and in advance of the third. The object in view in thus placing
the knives is to allow the wood to expand sideways as the knife enters it. After
passing the longitudinal or slabbing knives, the wood comes beneath a cross knife,
which finally cuts it into chips or sticks.
Also in the construction and use of a hinged or swivel blade, arranged automatically
to take up a different position angularly with the position previously assumed, by the
swinging of the blade through the necessary angle about the hinge; and further :-
In the shape or relative positions of the cutting blades; which for making two cuts
at right angles is T or L shaped; or when the object is merely or chiefly to
strengthen the blade, the section may be H, L, or Z as may be most convenient.
5° In a skew trough, along which the chips may be traversed from the cutting to
the bundling machine. The object aimed at in our method of skewing the trough, is
to turn the chips without disarranging them, from a vertical to a horizontal position,
in which they are more readily formed into bundles by the bundling machinery.
6° In machinery or mechanism for arranging the chips parallel to each other, so
that they may be readily formed by the bundling machines into bundles; where such
bundles are required to be made from piles of chips, or from sticks which are not
delivered already properly arranged. This consists of a hopper in which works an
endless band elevator, which delivers the chips carried up by it, into a narrow inclined
shoot, down which the chips or sticks slide, endways first, and shoot upon a slowly
moving endless feed belt, working at right angles to the shoot, upon which they are
thereby arranged and carried side by side and parallel to each other, to the bundling
machine.
A further device for picking up and arranging the sticks consists of a reciprocating
arm (or arms) provided at the end with a cross piece having a pointed steel wire or
picker. When the arm rotates either to the right or to the left, the pointed ends of the
cross piece penetrate one or other of the numerous chips in the receptacle below,
which on the ascent of the cross piece remain attached thereto. It will be understood
that the chips or sticks are thus picked up singly. A groove or slot is provided in a
fixed disc for the passage of the reciprocating arm. The slot however is too narrow
for the passage of the chips or sticks, which thus fall off singly into troughs below,
from which they are passed in an arranged form to the bundling machine. The
bottom of both trough and boxes may be arranged to be shaken to prevent any sticks
clinging thereto.

sticks comprising a measuring hopper, shaking and forming cylinders, and tying
apparatus.
7 a. Refers to means for automatically locking the agitator in an exact line with
the cylinders before and behind the agitator, and also to means for making the working
of the agitator of a more positive character.
7 b. Refers to the formers for forming the bundles into the proper shape. The
formers are hinged instead of fixed, and the outer ends of the two formers overlap,
each being cut away to half its depth over the overlapping parts, so that the outside
surfaces (front and back) of the formers are in line or flush with one another.

against which the sticks are pushed by a spring cam.

page_text: 7 d. Refers to a compressor or gripper for holding the chips or sticks forming the
bundle, tightly together, during the tying operation. The compressor consists of an
arrangement of two or more jaws, some of which may be fixed. The moveable jaws
are forced inwards towards each other (or towards the fixed plates) at the proper time
by means of toggles and ordinary levers.
And lastly to mechanism for tying together the chips or sticks forming the bundle.
This mechanism comprises in the first place means for laying the tying wire round
the bundle, where such wire is supplied in the form of a coil or reel, and cutting it off
to the proper length; the mechanism consisting of a novel arrangement of gearing
actuated from a simple crank and connecting rod. In the second place the mechanism
comprises means for fastening the ends of the tying wire, by twisting the ends round
each other, and this arrangement alone is needed, when the wire is supplied already
cut in suitable lengths. The twisting mechanism consists of a rotating spindle with
gripping jaws for holding the wire ends.

page_text: Improvements in Machinery for Cutting Wood and for Arranging
Sticks and Bundling the same into Bundles.
We ARTHUR WILLIAM GLOVER and MATTHEW HENRY GLOVER both of Potterdalo
Works, Dewsbury Road Leeds in the County of York Engineers 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 various improvements in the construction and arrangement
of machines for cutting (or splitting) wood into sticks, for the forming or arranging
of sticks into position, and for the feeding of sticks into bundling machines, and for
tying the same into bundles.
Our Invention consists:-
1° In a self acting feeding arrangement or motion, for feeding forward inter- 1
mittently the wood to be cut by means of feed rollers having their axes horizontal.
The rollers may be arranged either with fluted or other uneven surface, or with a
covering of composition, rubber, or other flexible material to avoid disfigurement of
the wood.
2° In feeding forward the wood by means of a revolving table, or circular trough, 1
or a series of troughs arranged in a circle into which the wood is filled, preferably
opposite to the knife or knives; and from which after passing under the knives, it is
discharged before again reaching the filling place.
An uniform intermittent motion is given to this circular trough, actuated by ratchet,
eccentric, or other suitable means, whereby the wood is fed forwards at a uniformly
intermittent rate, and split into uniform strips, blocks, or sections as may be
desired.
3° In a feeding arrangement consisting of two endless chains or belts, provided
with projecting plates or cross pieces, which act as propellors or form travelling
compartments, between which the wood is packed and carried forward horizontally
under the knives.
In all the above feeding arrangements special provision may be made for the
expansion of the troughs or trays when the knives descend into the wood, expanding
and splitting the wood. By these provisions all wedging of the knives is obviated,
and the latter can follow the grain of the wood as in hand splitting and the sticks
are allowed greater play after being split, thereby preventing jamming or over-
crowding.
4° In the arrangement and construction of the knives. When it is required to
subdivide the wood into slabs, before cutting the slabs into sticks, we arrange several
knives longitudinally. These knives are placed parallel but not in line with each
other, the first somewhat to one side and in advance of the second. Similarly the
second is somewhat to one side and in advance of the third. The object in view in

page_text: thus placing the knives is to allow the wood to expand sideways as the knife enters it.
After passing the longitudinal or slabbing knives, the wood comes beneath a cross
knife which finally cuts it into chips or sticks.
Also in the construction and use of a hinged swivel blade arranged automatically
to take up a different position angularly with the position previously assumed, by
the swinging of the blade through the necessary angle about the hinge, and
further.
In the shape or relative positions of the cutting blades; which for making at one
time two cuts at right angles is T or L shaped; or when the object is merely or
chiefly to strengthen the blade the section niay be H L, or Z as may be most
convenient.
5° In a skew trough, along which the chips may be traversed from the cutting to
the bundling machine. The object aimed at in our method of skewing the trough is
to turn the chips without disarranging them, from a vertical to a horizontal position,
in which they are more readily formed into bundles by the bundling machine."
6° In machinery or mechanism for arranging the chips parallel to each other, so
that they may be readily formed by the bundling machines into bundles, where such
bundles are required to be made from piles of chips or from sticks which are not
properly arranged. This consists of a hopper in which works an endless band elevator.
which delivers the chips carried up by it into a narrow inclined shoot, down which the
chips or sticks slide endways first, and shoot upon a slowly moving endless feed belt,
working at right angles to the shoot, upon which they are arranged and carried side
by side and parallel to each other, to the bundling machine.
A further device for picking up and arranging the sticks consists of a reciprocating
arm (or arms) provided at the end with a cross piece having a pointed steel wire or
picker. When the arm rotates either to the right or to the left, the pointed ends of
the cross-piece remain attached thereto. It will be understood that the chips or sticks
are thus picked up singly. A groove or slot is provided in a fixed disc for the passage
of the reciprocating arm. The slot however is too narrow for the passage of the
chips or sticks, which thus fall of singly into troughs below, from which they are
passed in an arranged form to the bundling machine. The bottom of both trough
and boxes may be arranged to be shaken to prevent any sticks clinging thereto.
7° In an improved construction and arrangement of gear for bundling chips or
sticks, comprising a measuring hopper, shaking and forming cylinders and tying
apparatus.
7a. Refers to means for automatically locking the agitator in an exact line with the
cylinders before and behind the agitator, and also to means for making the working
of the agitator of a more positive character.
7 b. Refers to the forniers for forming the bundles into the proper shape. The
formers are hinged instead of fixed, and the outer ends of the two formers overlap,
each being cut away to half its depth over the overlapping parts, so that the outside
surfaces (front and back) of the formers are in line or flush with one another. We
do not confine ourselves to the use of only one set of formers, in one machine. The
bundles may be rotated by imparting a rocking motion to the formers by mechanism
analogous to a silent ratchet feed as common in many other descriptions of wood
machinery.
7c. Refers to means for arranging the ends of the bundle whilst in the cylinder level
at the ends by means of a diaphragm automatically inserted across the cylinder against
which the sticks are pushed by a spring cam.
7 d. Refers to a compressor or gripper for holding the chips or sticks forming the
bundle, tightly together, during the tying operation. The compressor consists of an
arrangement of two or more jaws, some of which may be fixed. The moveable jaws
are forced inwards towards each other (or towards the fixed plates) at the proper time
by means of toggles and ordinary levers.

DESCRIPTION OF DRAWINGS.
The drawings are hereunder described seratim with reference to the previous con-
secutive paragraphs.
1° Fig. 1 is a front elevation and Fig. 2 a side elevation shewing our improved
arrangement for feeding with horizontal rollers. a a are the fecil rolls having their
axes horizontal. The two axes are preferably geared together as shewn, and the
rollers are actuated by means of a ratchet wheel on the shaft a', ratchet lever b,
eccentric rod c, and eccentric d, from the main driving shaft e. This arrangement of
horizontal feed rollers is of advantage where the sticks to be fed into the machine are
comparatively short.
20 Figs. 3, 4 and 5 are respectively side elevation, front elevation, and plan of a
wood cutting machine having one of our circular trough tables applied thereto. fis
the circular table with circular feed trough g in one piece, or as shewn, in removable
segments or compartments, which can be filled and emptied separately away from the
machine if desired. A. uniform intermittent rotary feed motion is given to the table,
and consequently also to the circular trough g, (passing it under the cutting knives,)
by means of a circular rack h, under the table, rack pinion i, ratchet wheel and
lever, eccentric rod l, and eccentric m keyed on the main driving shaft n.
Figs. 6 and 7 are respectively plan, and front elevation partly in section, of a table
with the troughs g arranged radially in a circle. The feed mechanism for rotating
the table may be practically the same as that just described for Figs. 3-5, but must
be so designed that it feeds forward an angular distance equal to that between two
adjacent troughs. The sides of these troughs g are formed as flat spring grippers,
with a slot about midway of their height, and on their inner portion, so as to allow of
the passage of the troughs over the fixed cam h, which gradually forces out the wood
as the troughs pass over the more projecting portions of the fixed cam. A knife i,
placed radially, is arranged to split the blocks in two halves, and one or more knives k,
placed circumferentially, then split the wood into chips or sticks. The arrangements
shewn in Figs. 3-7 are of advantage for utilizing the waste wood from saw mills.
3° Fig. 8 is a plan of a vertical arrangement of two endless chains or belts o, o,
with projecting plates or cross pieces p, which act as propellors, or form travelling
compartments, between which the wood is packed, and carried forward horizontally
under the knives or knife q, preferably T shaped in section as shewn.
Fig. 9 is a part front elevation, and Fig. 10 a plan of a single endless chain or belt
arrangement (or two chains at proper distance apart may be used,) the projections p
in this case being vertical. The knife q, preferably V shaped, in its descent, stops
short of the projections or belt or chain, the distance however being so short, that the
wood is effectually split quite through.
4° Fig. 11 is a front elevation and Fig. 12 a plan shewing a hinged or swivel
blader, hinged to the reciprocating cross-head s. To the blade r, is attached one end
of the short connecting link t, the other end being connected to the sliding rod u,
which can slide horizontally in a guide fixed to the cross-head s. By means of
automatic mechanism; for example a lever and link connection to a cam on a second
driven at half the speed of the main shaft, or a cam on the main shaft similar to those
formerly used for driving the frisket frames in printing machinery, the blade can be
swung alternately to the right and left, after or between each blow, so that the blocks
of wood are cut into chips, owing to the cross directions of the blade during alternate
blows.

page_text: Figs. 13, 14, 15 and 16 are horizontal sections of knife blades as previously
referred to.
5° Fig. 17 shews side and end views of a skew trough in which the trough g is
shewn skewed or twisted about the corner or edge v as an axis, instead of about a
point or line in the centre of the trough section. Fig. 37 represents a rapidly
reciprocating slide working under the sticks, as they are delivered from the before
mentioned skew trough, and by means of ratchet teeth formed thereon, feeds forward
the sticks, and sifts any dirt or bark, leaving the sticks clean.
6° Figs. 18, 19, and 20, are respectively side elevation, end elevation, and plan, of
our first referred to apparatus for arranging loosely piled or heaped chips parallel to
each other, ready for the bundling machine. w is an endless band elevator, which
gathers the chips from the trough a, in which they are loosely heaped, and raises and
empties them into the narrow shoot y, down which they drop endways, on to the
travelling belt z, or boxes; being deposited on this parallel to each other; i.e. at
right angles to the direction of the belt z.
Figs. 21 and 22 are respectively front and side elevations, of the second of our
apparatus for arranging the chips for the bundling machine. 1 is a reciprocating arm
or lever, with a T head provided, at the two ends thereof with pointed wire pickers 2,
which strike alternately into the two troughs 3, raising each time attached to one or
other of the pickers, a single stick or chip. The Thead of the reciprocating arm,
when moving through its vertical position, passes through a slot in the diaphragm or
disc 4, but which slot is too narrow and short to allow the chips to pass, and the latter
therefore drop off into the narrow shoot y, down which they drop on to the travelling
belt, or boxes, as just above mentioned.
7° Figs. 23, 24 and 25 are respectively side and front elevation, and plan, of a
machine for bundling and tying sticks and chips, constructed in accordance with our
improvements already referred to. Figs. 26 to 36 represent details of the same, which
will be hereafter referred to.

delivering them into the measuring hopper b, through which they drop into the

link e.
7a. Midway in the forming cylinder, is the agitator d, to which at the proper
periods a rapid to-and-fro motion is imparted in a positive manner, (i.e. not partly by
springs,) by means of the short link e, (soe Fig. 26) rocking lever f, on the shaft g, to
which an oscillating motion is imparted by links and levers from a cam on the main
shaft h. Figs. 27 and 28 are respectively side elevation and plan, corresponding to the
cross view Fig. 26. The lever fengages in a square notch near the end of the hinged
After the chips have been arranged by the agitator d, in order to stop the
motion of the agitator, the hinged link e is pulled sideways as indicated by the arrow,
disengaging it from the rocking lever f, by means of the rod k, actuated indirectly by
connections from a cam on the main shaft h. The end of this rod k is enlarged, so
that on the rod being drawn forward to stop the agitator, this enlargement fits in a
slot formed on the underside of the agitator d, and locks the latter firmly in position.

arrangement of formers and mode of operating them. are the formers hinged at i,

are inoved together and apart at the proper times, by means of the levers and links m,
shafts n, and levers o, o', from the cam p on the main shaft h. The levers o, o¹, are
kept pressed against the cam p by the springs r. Two sets of formers are provided in
the machine as shewn, one set on each side of the agitator d. The formers jare
preferably so actuated, that whilst both sets close together at one and the same time,
the outer set retains its hold on the bundle longer than the other. This we effect by
the arrangement shewn in Fig. 30. The cam p catching against the lever o, depresses
it opening the first set of formers, and afterwards on coming against the lever o¹,
opens the second set of formers, somewhat later than the first. The link q connecting
the two levers being slotted, the motion of the first lever o, does not compel the

page_text: second lever o¹ to move. After both lovers have been moved by the cam, they are at
the full distance apart which the slotted link will allow, so that although the lever o
is first relieved by the cam, it cannot be moved by its spring until the second lever o¹
also is released.
7. Under this heading a diaphragm has been referred to for arranging the ends of
the bundles evenly or level, the drawings and description hereunder however shew,
and described our proposed arrangement for actuating such diaphragm as applied to
the main pushers, which is actuated in one direction by a cam and the main shaft h,
and in the other by a long spiral spring t. At the back end of the pusher
rod is fixed a bracket u, to which is attached a spring buffer v.
An auxiliary
cam won the main shaft h, gives a short forward stroke to the pushers, which
pressing against the end of the bundle, makes it even, and then recedes again.
7 d. x (see Fig. 24) are the gripper plates for holding the bundle during the
tying operation. These are pressed together by means of the toggle levers y, actuated
from the main shaft by means of the lever z. Springs as shewn are provided to
prevent breakage from excessive pressure.
Figs. 31, 32, and 33 are respectively front, and two side elevations, of our improved
mechanism for tying together the sticks or chips forming a bundle. Figs. 34 to 36,
are enlarged views of the details hereunder referred to.
a is the wire for tying the bundles, supplied from the coil b. The wire is first passed
through the guide c, and the projecting end thereof caught by a self-acting nipper d,
on the end of an intermittently rotating cranked arm e; by which the wire is carried
completely round the bundle and slightly past, so as to cross itself in line with the
V shaped gripping piece f, on the lower end of the vertical spindle g. A holding
piece h, sliding on the spindle g, with a corresponding V shaped end, is pulled
down at the proper moment by the spring i; and the end of the wire passing through
the guido is cut off by the cutter k. Immediately afterwards the spindle g
is rotated by means of the bevel wheels j, and toothed wheel and ratchet gear
see Fig. 23.
The cranked arm e is actuated from the driving or main shaft h Fig. 23 by means
of the crank 1, connecting rod 2, rocking lever and oscillating bevel wheel 3, and
the toothed wheels 4 41, the latter shewn enlarged in Figs. 34 and 35. The cranked
arm e, which is keyed on the shaft 5, is rotated from the wheel 4' by means of the
clutch 6, in the direction shewn by the arrow. When the arme (carrying the wire)
has been rotated to its full extent round the bundle, and the wheel motion is about to
be reversed, the long arm of the opposite clutch 7 is caught by the stop 8 on the
large wheel 4, and the short end of the clutch 7 raised thereby, so that during tho
next revolution of the wheel 4, the clutch 7 rides on the outside of the clutch disc 9,
and does not operate the latter until it again comes round to the notch 91. This
causes the cranked arm e to remain stationary for the proper length of time before
being reversed to fetch round a fresh length of wire.
The holding piece is prevented from dropping till the proper moment by the
link 10 resting on the projecting rest 11, until it is pushed off by the lever 12. The
end of the wire is released from the nipper d, by the lower part of the lever 12¹
opening the nipper.
a,
In order to allow the end of the cranked arm e to pass the wire when completing
its revolution, the hinged lever c¹ carrying the wire guide c is pushed aside by the
end of the arme coming in contact with the lower curved part of the hinged lever c¹.
See Figs. 36.
