Improvements in the Construction of the Heads of Moulding,
Planing, and Chipping Machines for Facilitating the Setting
and Adjustment of the Knives and Cutters.
I SAMUEL BASTOW of the firm of Messieurs S. Bastow & Son of New Dock Saw
Mills Chadwick Street Leeds in the county of York Timber Merchant do hereby
declare the nature of this Invention to be as follows:-
The object of my invention is to facilitate the correct setting and adjustment of
knives and cutters of the above machines. I employ preferably loose square heads
which can be attached to the spindles of the above machines, on the loose square
heads. I place on each side where the knives or cutters are required two or more
cones one being inverted, abutting or near which is a pivotted plate bevelled similarly
to the cones, these plates carry or bear against the knives or cutters, the cones are
each loose upon a centre pin or screw arranged so that turning either of the centre
pins one way its cone rises, and so moves the pivotted plate one way and on reversing
either of the centre pins its cone lowers, so moving the plate the other way the plates
and.knives can by this means by correctly adjusted and fixed to cut tennons or
grooves or other suitable angles or recesses with great despatch and by any ordinary
workman, in lieu of the cones, angle plates may be used.

Improvements in the Construction of the Heads of Moulding,
Planing, and Chipping Machines for Facilitating the Setting
and Adjustment of the Knives and Cutters.
I SAMUEL BASTOW of the firm of Messrs. S. Bastow and Son New Dock Saw
Mills, Chadwick Street, Leeds, in the county of York Timber Merchant, 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 object of my invention is to facilitate the correct setting and adjustment of
knives and cutters of the above machines.
I employ loose square, hexagonal, or other shaped heads which can be attached to
the spindles of the above machine.
For facilitating the correct and quick setting of the knives, I place the cutter
blocks or loose heads upon adjustable spindles carried on slides, adjustable by means
of screws on a suitable frame; between the spindles is a bed, upon which is placed a
sample of the board to be tongued and grooved, so that when the knives require
sharpening, the heads are taken off the spindles of the machine, and after the knives
or cutters are reground, they are placed upon the heads and slipped on to the
spindles on the setting apparatus, and instantly set to the exact angle and position
they before occupied, by means of the adjustable strips and sample board upon
the bed.
I place on each side where the knives or cutters are required, two or more cones,
one being inverted abutting or near which is a pivotted plate, bevelled similarly to
the cones, these plates carry or bear against the knives or cutters, the cones are upon
a centre pin or screw, arranged so that by turning either of the centre pins one way
or the other, its cone advances or recedes, and so moves the pivotted plate one way or
the other, and on reversing either of the centre pins, its cone moves in an opposite
direction, so moving the plate the other way, the plates and knives can by this means
be correctly adjusted and fixed to cut tongues, or grooves or other suitable angles or
recesses with great despatch, and by any ordinary workman; in lieu of the cones,
any other method of adjusting the angle plates may be used.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation of improved cutter heads upon adjustable spindles for
facilitating the setting and adinstment of the knives and cutters

page_text: screws P¹ and P' on a suitable frame C; between the spindles B, is a bed D, upon
which is placed a sample E of the board to be tongued and grooved or otherwise
operated upon, so that when the knives F require sharpening, the loose heads are
taken off the spindles of the machine, and after the knives or cutters F are
reground, they are placed upon the heads and slipped on to the duplicate spindles B
on the setting apparatus, and instantly set to the exact angle and position they
before occupied, by means of the adjustable strips and sample board E upon the
bed D.
The spindles B can be raised or lowered by means of the lock nuts B¹ and B³.
For adjusting the knives I place on one or both sides of the knives, adjustable
inverted cones G (or ordinary cones) bearing against the side of the pivotted
plate K, bevelled similarly to the cones, the other side of the plate bearing against
the cutter; these cones are adjustable by means of the centre pins or screws J,
arranged so that by turning either of the pins one way or the other, its cone
advances or recedes, so moving the pivotted plate, and on reversing either of the
centre pins its cone moves the plate in the other direction the plates and knives
can by this means be correctly adjusted and fixed to cut tongues and grooves or
other suitable angles or recesses with great despatch, and by any ordinary workman.
Or instead of the cones, a pivotted plate K' is employed having screws L L, and
a centre pin M, with a square neck tapped into the cutter block and radiating to any
angle in the slot N of the pivotted plate, by this means by simply slackening the
screws L L, the plate can move on its pivot, to any angle required, and slide up or
down on the square of the pivot, and by tightening up the screws L L, the plate is
again secured the knives bearing against the plate can be taken off and put on without
disturbing the angle or position of the plate; instead of the adjustable plate, fixed
plates may be formed upon the cutter block, some straight, and others at the angles
most generally used in cutting grooves and tongues, though adjustable plates are
preferable.
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 :-
1. The use of adjustable and moveable side pieces, cones, or their equivalents upon
cutter blocks, for regulating the angles or positions of the cutters or knives, as and
for the purposes shewn and described.
2. The use of fixed side pieces upon the cutter blocks, as and for the purposes
shown and described.
