Improvements in Machinery for Cutting and Grooving Wood,
particularly Applicable for the Manufacture of Boxes.
We, GARNETT CLAUGHTON, JOHN WILLIAM CLAUGHTON, and JOHN BUTLer, all
of Bramley, near Leeds, in the County of York, Engineers, do hereby declare the
nature of this invention to be as follows: -
Our invention relates to machinery for cutting and grooving wood, which is
particularly applicable in the manufacture of boxes described in the Specification
of Claughton and Claughton's Patent No. 21536, A.D). 1896.
According to our invention we construct a framework carrying a table on its
upper surface, and on the table an adjustable hopper is provided for the purpose
of receiving several sections of wood to be worked. A sliding plate is mounted on
the table, its under side being connected to a lever which is fulcrumed in the base
of the framework, and the said lever is actuated by a cam or crank situated on a
rotating shaft, in such a manner as to give the required movements to the sliding
plate._
A vertical slide carrying a number of mortice drills or cutters, is mounted in
the frame of the machine, and a double ended lever, one end of which is actuated
by a cam situated on the shaft, is connected to the slide in such a manner that
the drills may be raised or lowered for periods relatively to the movements of the
sliding plate. Two circular saws, cutters or sets of knives are arranged for the
purpose of cutting or beveling the ends of the sections of wood to be worked, and
the positions of these cutting tools may be adjusted to suit the length of the sec-
tions under treatment. The side of the hopper is provided with an adjustable
plate which admits of the passage of one section of wood as it is fed forward by
the sliding plate, and weighted rollers or other holding appliances are employed
for the purpose of holding the material down to the table during the cutting and
grooving operations.
The sliding of the plate removes the lower section of wood from the hopper
and carries it over the mortice drills, where it comes to a standstill, and on the
slide rising the drills enter the under surface of the wood. The sliding plate then
advances a second time and the drills cut parallel grooves in the wood, and during
a pause of the sliding plate the drills are lowered by the slide, when the sliding
plate advances for the rest of its stroke and the section of wood is delivered at
the back of the machine.
One or more of the mortice drills may remain stationary in the up position for
cutting grooves the full width of the wood, and where it is desired to cut or bevel
off a certain distance only of the ends of the wood, the sliding plate may be

page_text: caused to withdraw the section after the desired amount of cutting has been per-
formed, or the circular saws or cutters may be actuated so as to throw them out
of action at any required time in the length of the stroke:
Improvements in Machinery for Cutting and Grooving Wood,
particularly Applicable for the Manufacture of Boxes.
We, GARNETT CLAUGHTON, JOHN WILLIAM CLAUGHTON, and JOHN BUTLER, all
of Bramley, near 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 machinery for cutting and grooving wood, and it is
particularly applicable in the manufacture of boxes described in the Specification
of Claughton and Claughton's Patent No. 21536 A.D. 1896.
In order that our invention may be clearly understood, we will proceed to
describe same with reference to the accompanying drawings, in which similar
letters refer to like parts in all the figures.
Figure 1 is a side elevation with a portion of the frame removed, Figure 2 is
a plan, and Figures 3 and 4 are cross sections, of a machine constructed according
to our invention.
A is the frame of the machine which carries a table B on its upper surface,
and C is a hopper which is carried on carriages J). The hopper C is composed of
four uprights, two of which are adjustable in slots D' to enable the hopper C to
take boards of varying width; and the carriages D, are carried on slides E, which
enable the said carriages D to be adjusted towards or away from each other, at
the same time adjusting the size of the hopper C in a transverse direction. Fare
circular saws, which are carried on spindles F¹, mounted in pivoted brackets F³
which are centred on pins F3 on the carriages D), and segmental slot adjust-
ments F permit of the adjustment of the brackets F2 and thus allow the saws. F
to be set at any required angle. G is a sliding plate, which is mounted on a
carriage G¹ sliding on a slide G2, and H is a lever which is connected to the car-
riage G by means of an adjustable link H'. The lever H is fulcrumed on a
shaft H2, which latter is adjustable in position in the frame A, bracket H³, and
lever H, so as to enable the length of the lever H to be adjusted for the purpose
of adjusting the stroke of the carriage G¹, and the said lever H. is actuated by a
stud H which travels in a cam way H³ of a cam H6 carried on a shaft J. K is
a frame sliding vertically in slides K', and K2 are drill spindles which are carried
in bearings K³ adjustably connected to the frame K in, slots K. The drill
spindles K carry suitable mortice drills or cutters K³, and the frame K is con-
nected to one arm of a double ended lever L, the opposite end of which is actuated
by a cam L' carried on the shaft J, in such a manner that the drills are raised or
lowered for periods relatively to the movements of the sliding plate G. M and N
are rollers, which are carried on arms M' and N', and weight is given to the said

page_text: rollers by means of a weighted arm P which is carried on a shaft P¹ to which
the
arms Mand N are also keyed. R is a shaft which is driven continuously
through the medium of a belt pulley R¹, and Rº are drums which through belts R³
drive the pulleys of the saws F. S is a shaft which is driven continuously through
the medium of a pulley S¹, and S is a drum which through belts S³ drives the
pulleys of the drill spindles K T is a cone-pulley which is carried on a pin T
adjustably connected to the frame A in a slot T, and a change pinion T3 gears
with a spur wheel T, which latter through the medium of a pin T5, pinion To and
spur wheel Timparts motion to the shaft J. V is a clutch, which is actuated
through a fork V₁ by means of a hand lever V2, and the movements of the latter
allow the sliding plate G and the frame K to be thrown in and out of action at
will.
The wood to be cut and grooved, is placed in the hopper C, and on the hand
lever V being moved so as to throw the shaft J into action, the sliding plate G
advances and moves the lowest piece of wood from the base of the hopper C
towards the saws F and over the frame K, where it comes to a standstill. The
frame K now rises and the drills K³ enter the under surface of the wood, and as
the sliding plate G advances a second time the drills K cut parallel grooves in
the under surface of the wood, until, during a pause in the movement of the
sliding plate G, the drills are withdrawn, and the grooved wood is delivered on the
table B at the back of the machine. During this grooving of the under surface
of the wood, the saws F which are continually rotating, bevel off the edges of the
wood, so that the wood when ejected is not only grooved but it is beveled ready
for forming the side of a box. By supporting one or more of the mortice drills
independently of the frame K, grooves can be cut the full width of the wood with-
out leaving ungrooved portions at the top and bottom.
By altering the shape of the cams, the character of the feed imparted by the
sliding plate G may be varied to suit the requirement of the work to be produced,
and the stroke of the frame K might also be varied in the same way. In some
cases where grooving is not required, the frame K may be lowered out of action,
or the saws F might if desired be removed and the machine be employed for
grooving only. The sliding plate G may be caused to withdraw the sections of
wood after the desired amount of cutting has been performed, and the circular
saws F and the drills Kō may be thrown out of action at predetermined points,
so as to cut the wood to any desired depth down the sides of the board.
Instead of employing the circular saws F for beveling the wood, cutters or sets
of knives might be employed if desired.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The combination of the hopper C, saws F, and sliding plate G, substantially
as and for the purposes set forth.
2. The combination of the hopper C, frame K carrying drill spindles K2, and
the sliding plate G, substantially as and for the purposes set forth.
3. The combination of the carriages 1) carrying opposite sides of the hopper C,
