Improvements in Machines for Cutting and Trimming Wood or
other suitable Material to an Angle, Bevel, Mitre, Square, or
other desired Shape.
REUBEN JOHN LINES 66 Colwyn Road Northampton in the County of Northampton
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
My invention consists of improvements in my Patent No. 8414-95 and are as
follows.
I find it is desirable that a longer cut should be taken than is convenient in my
first machine, and to effect that I alter the shape of the front or L plate and also the
shape of the knife or cutter holder, I also make the semicircular slot or slots (that
are in the bed) in a separate plate or plates, and attach one to each end of the bed or
table of the machine. The angle plates or plate which form the abutment or abutments
for the material to rest against are fitted to this slot in the manner before described
in my Patent No. 8414-95, but with the following improvement. The portion of a
semicircular ring which slides within the slot and guides the angle plate or abutment
is made T shaped in section and instead of being fastened on the bottom of angle
plate, it is placed through a suitable opening in the bottom of said plate and fixed
in such a manner that the apex or front edge of the angle plate is more easily
adjusted to its correct position.
The rack bracket which was bolted to the bed I now make in one piece with
the bed, but without the rack, this bracket portion of the bed forming one side
of the guide slot for the cutter holder, and also as before the attaching part for
the front or L plate.
The front or plate I now carry to a sufficient height above the bed to properly
support the cutter holder, and also to enable me to have therein a horizontal slot which
is made of such a length as is required by the length of cut the machine is to take,
above this slot place a toothed rack (preferably made in one piece with the Lor
front plate) running rather longer than the whole length of the slot, with the teeth
preferably downward, on the top of this same plate above the rack I form a level
surface to allow for the easy travelling of guides or rollers to support the knife or
cutter holder. The inside of this Lor front plate is made true and in such a manner
as to reduce the friction of the knife or cutter holder upon it.
The front or outside of rack and slot is also made true and parallel with the
inside of plate, so that the plate will form a guide to the knife or cutter holler
and prevent the cutter from springing inwards.
I also alter the shape of the knife or cutter holder and make upon the side next to
the front or L plate one or more projections or spindles, one or more of which work
within the horizontal slot which forms a guide, to one of the projections or spindles
I attach a pinion which is in such a position that it gears directly with the rack.
To increase the power I attach to this pinion a toothed wheel which is geared to a
second pinion on a second projection or spindle of the knife or cutter holder, and
to this second pinion I attach a suitable wheel, handle, or lever whereby I
transmit the power required to move the knife or cutter holder, and knife or knives
in either direction, and so cut the material (when it is placed upon the bed and resting

page_text: against the angle plate or plates) to the shape required. The cutter or knife may be
fixed to the holder at any required angle suitable for the material to be cut. The
front plate is adjusted to the holder by means of bolts or screws.
I also in some cases prefer the angle plates or abutments to be guided to their
position by slots at different angles, instead of the semicircular slots.

Improvements in Machines for Cutting and Trimming Wood or
other suitable Material to an Angle, Bevel, Mitre, Square, or
other desired Shape.
I, REUBEN JOHN LINES of 66 Colwyn Road, Northampton, Engineer, 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 :-
This invention relates to improvements in machines for cutting and trimming wood
or other suitable material to an angle, bevel, mitre, square or other desired shape
whereby the operator is enabled to perform any of the operations above mentioned.
The machine is mounted on suitable supports and consists of a plate or table upon
which the material to be trimmed or cut is laid and the said table has on its upper
face suitable angle plates or abutments against which the material to be cut or
trimmed may be pressed.
The cutters or knives are carried in a holder movable in a guide-space formed
between the plate or table and a front or L plate, the latter having formed thereon a
rack into which gears a pinion carried loosely on a spindle attached to the cutter
holder. A hand lever is fixed to the said pinion and by turning the latter the
cutters are traversed the length required to perform the cutting or trimming
operation.
When the material to be cut or trimmed requires greater power, I form with or
attach to the pinion mentioned a toothed wheel gearing with a pinion carried on a
second spindle fixed to the cutter holder and attach the hand lever to the latter
pinion.
The invention will be fully understood by reference to the drawings accompanying
this specification, wherein like letters of reference indicate like parts.
Figures 1 and 2 are perspective views of a cutting or trimming machine
constructed in accordance with this invention, looking towards the front and back
of the machine respectively.
Figure 3 is a front elevation of the said machine with the supports removed.
Figure 4 is a plan and Figure 5 a cross central section of Figure 3.
Figure 6 is a face view and Figure 7 a side view of the cutter holder, Figure 8
being a sectional plan taken on the line Z. Z. of Figure 6 and showing the position of
the cutters or knives with respect to the cutter holder.
Figure 9 is a plan of the underside of an abutment or angle plate.
Figure 10 is a plan of the underside and Fig. 11 a side view of a slide for adjusting
an abutment plate.
Figures 12 and 13 are side elevation and front view respectively of the spindle and
plate hereinafter referred to.
Figures 14 and 15 represent side and front view respectively of a plate and spindle
hereafter described.
A is the plate or table supported by and secured to the stand or frame A' and leg A2
(see Figures 1 and 2).

page_text: The said table A is shaped to allow slotted plates B to be placed therein and has an
extension A 3 to which the front or L plate C'is attached by bolts C 2 passing through
the holes in the flange C'.
The cutter holder D moves in the guide space formed between the slotted plates B
and the front plate C before mentioned, the inside of the latter being perfectly true so
that the former is not impeded in its movement.
The angle or abutment plates E are recessed on their underside to allow a
segmental ring F to be placed within the said recess E¹ to allow of the adjustment of
the said abutment plates E.
The segmental ring F is provided with lugs F passing downward into the semi-
circular slots B3 of the plate B in which they should fit and yet work freely, and may
be tightened in any desired position by the bolt B' passing downward through the
plate E and locked by the bandle or lever B 2.
It is desirable that the apex E2 of the abutment plate E should be capable of
adjustment to the required position, i.e. the apex E 2 brought truly into line with tho
edge of the slotted plate B and this adjustment is obtained by means of the segmental
ring or slide F before mentioned. The plate E and slide F are connected movably
together by bolts F 2 and eccentric bolt F 3, the said bolts having cheese heads and
being clear of the table A or plates B. The holes E 3. E 4 in the plate E are
slightly oval in shape, it will be seen therefore that when the eccentric bolt F 3 is
turned slightly in the hole E4 the abutment plate E will be moved slightly and its
apex E 2 brought to the desired position and retained there by the bolt B¹ locked
by the handle or lever B 2.
The lugs F¹ on the underside of the slide F form a segment of a circle of the same
radius as the semicircular slots B 3.
The said plates E are thereby adjusted to any required angle and allow the wood
or other material to be laid on the table and pressed against the said plates either on
the right or left hand, and thus allow the operator to cut the material to any
desired angle on either side.
The front or L plate C is made sufficiently high above the table A to give support
to the cutter holder D and has formed near its top a slot C3 sufficiently long to
allow the spindle G which passes through the said slot attached to the cutter
holder D to traverse the required distance.
Near the top of the plate C a rack C 4 preferably formed integrally with the
said plate C is formed.
The teeth of the rack C4 are preferably downward to obviate any clogging by
chips or other matter.
On the top of the plate C there is a projection C5 upon which revolve anti-friction
rollers H carried by bolts H' in a plate H2, the bottom of the latter moving along
the upward face of the rack C4. Guides are thereby formed by which the cutter
holder D may be more readily moved to and fro by the operator.
The front or outside of the rack C4 and the front surrounding the slot C3 are made
true with the inside of the plate C so that they will form a guide (when the
pinion J hereinafter described is placed in position on the spindle G) to the cutter
holder D and prevent it springing inwards.
Eccentric bolts Cx pass through oval holes in the flange C of the plate C and
through holes in the extension A 3 of the table A and when the said eccentric
bolts are slightly turned the plate C is moved slightly inward toward the cutter
holder D to cause the latter to fit snugly between the plates C and B.
To the ends of the plate C are attached by bolts K', brackets K passing downwards
to the ends of the table A and secured thereto by bolts or other means passing through
oval holes in the said plates K thus allowing the latter to move inward when the
plate C is adjusted as before described.
It will be seen that the plate C is shorter at the bottom than at the top so that
any cuttings or chips may be projected out of the guide space by the projections D'
on the cutter holder D. At the front of the latter is attached by bolts G¹ a plate G 2
having formed thereon the spindle G before mentioned. The said spindle G passes

page_text: through the slot C3 and carries loosely the pinion J gearing with the rack C4
to which the handle or lever L may be attached when thin material is to be cut.
To increase the power, however, as required when cutting thicker material, I form
with or attach to the said pinion a spur wheel J gearing with a pinion J 2
carried on a spindle or projection H 3 on the plate H 2 attached to the cutter
holder D. The handle or lever L (shown only in Fig. 1) is placed in a recess J3
formed in the plate J 4 on the side of the pinion J 2 and by turning the said handle L
the cutter holler D is caused to traverse to and fro.
The cutters or knives M are placed at any angle suitable for the material to be cut
and secured to the holder D by screws D3 and when in position form a true face with
the holder D and fit snugly in the guide space. A projection D2 is provided at
the bottom of the cutter holder D to slide within a groove formed in the bottom of the
plate C and thus help to keep the holder D from tipping.
I may form the slots in the plates B at different angles instead of the semicircular
slots described and shown.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is;
1. In a mitring or like machine, a vertical front guide plate adjustably mounted
upon the frame, having a horizontal rack and a projecting strip formning a race-way
for anti-friction rollers mounted on a cutter holder and having a recess or groove
along the bottom adapted to receive a projecting strip on the cutter holder to prevent
the same tipping, substantially as described.
2. A bed plate made in one or more parts removable from the machine and
forming with the front guide plate a guide space in which the cutter holder can slide,
substantially as described.
3. For a mitring or like machine, an improved cutter holder provided with
anti-friction rollers and with wedge shaped pieces to clear the chips from the groove
or guide space in which the holder slides, substantially as described.
4. The devices for moving the cutter holder by means of a rack and pinion
either with or without the reducing gear, substantially as described.
5. An abutment or angle plate provided with the device for adjusting its position
on the bedplate, substantially as described with reference to Figures 4, 9 and 10
of the accompanying drawings.
