I WILLIAM SANDY of Radcliffe on Trent in the county of Nottingham Gentleman
do hereby declare the nature of the said invention for AN IMPROVED COMBINED
LATHE, CIRCULAR SAW AND ANGLE CUTTER to be as follows:-
The object of this invention is to utilize the lathe for the purpose of cutting with
the circular saw, and also forming or cutting angles for various purposes.
With this view I provide the lathe with a table arranged above the headstock and
fix a circular saw to the end of the spindle, the saw revolves in an aperture for the
purpose in the table.
.
An angle cutter or mitre is adapted to the lathe as follows:-The mitre or angle
cutter consists of a semicircular plate with a guide by which to cut the angles; in this
plate is an aperture of form similar to it, the plate turns on a pivot fixed to a slide
moving in a slot in the table.
This semi circular plate is marked with a scale by which the angles are set, and
when arranged in any desired position it is fixed by a thumb screw.

An Improved Combined Lathe, Circular Saw, and Angle Cutter.
I WILLIAM SANDAY of Radcliffe on Trent in the county of Nottingham, Gentleman
do hereby declare the nature of the said invention for "AN IMPROVED COMBINED
LATHE, CIRCULAR SAW AND ANGLE CUTTER" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement and accompanying drawings, that is to say :-
The object of this invention is to utilize the lathe for the purpose of cutting with the
circular saw, and also forming or cutting angles for various purposes.
With this view provide the lathe with a table arranged above the headstock, and
fix a circular saw to the end of the spindle, the saw revolves in an aperture or division
for the purpose in the table.
An angle cutter or mitre is adapted to the lathe, as follows: the mitre or angle
cutter consists of a semicircular plate with a guide by which to cut the angles; in
this plate is an aperture or semicircular slot. The plate turns on a pivot fixed to a
slide bar, moving in a slot or groove in the table. This semicircular plate is marked
with a scale by which the angles are set, and when arranged in any desired position it
is fixed by a thumb screw.
The following description of the apparatus and its method of employment will be
more clearly understood on reference to the accompanying drawings.
Fig. 1 represents a lathe of the description embodying my invention seen from the
side of the treadle, Fig. 2 being a separate view of the mitre cutter.
A is the table, which is hinged at B so that this part forms a flap C, which can be
raised or lowered more or less as required by aid of the rod, or stud D, sliding in a
socket or some equivalent contrivance E, and firmly held in position when sloped as
required, by a thumb screw F. By this means any number of pieces of a similar
width can be cut at the same angle, it can therefore be used for mitring up the angles
of boxes, cornices, or mitres of any width.
This flap or fall is provided with an adjustable guide, sliding on a bar, on which are
marked a scale of inches, for measuring the width of the article to be cut, and
marking it off.
The whole table top can be raised or lowered as required by means of the rods D.
and G. to admit of cutting rabbets, or grooves of any depth, such for instance as
tongueing splayed linings for windows and so forth.
H is the circular saw, and I. I. are guides or fences for guiding the work under
operation. At the opposite end of the mandril to that occupied by the saw, chucks
can be fixed for holding boreing bits. At this end of the lathe is an adjustable table J,
raised and lowered by rack and pinion, and fixed in position by set screws, it can also
traverse longitudinally and laterally for the accommodation of the work under
operation. It is also provided with racks and jaws for holding work, and guides
or fences for guiding it.

The angle cutter Fig. 2 consists of a semicircular plate K, or quadrant bearing
slot K', of similar formation, it is screwed to the underside of the arm L-both the
quadrant and arm pivot on the axis M. A metal bar N sliding in a slot or groove O,
in the saw table top Fig. 1, is connected to the quadrant by the pivot or axis M.
The wood to be cut is placed in front of the arm L, and is then forced up to the
saw. This arm L can be set at any angle by means of the quadrant K, and then fixed
at this angle by the set screw P. This Figure is shown on an enlarged scale.
There is also a double mitre block having an arm attached which is furnished with
a slide stop, for cutting any desired length of material, the arm being provided with a
scale by which the slide is regulated according to the length to be cut.
A square cutting block is employed for cutting perfect right angles in a precisely
similar manner.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1st. A table A, adapted to lathes, which can be raised or lowered as desired by the-
rods D and G, and having a movable flap C, capable of adjustment to bring the work
towards the circular saw H, at any angle required to be cut, such table being provided
with guides or fences I, I, for guiding the work, and slots O, for the reception of the
arm or sliding bar N of the mitre cutter.
2nd The sliding adjustable table J, raised and lowered by rack and pinion and
fixed by set screws capable of moving longitudinally and laterally to accommodate
work performed by the lathe.
3rd. The angle cutter or mitre K, with arm L, semicircular slot K', and slide
bar N, moving in the slot O, in the table, the whole as and for the purposes herein
set forth and as illustrated by the accompanying drawings.
