ANDREW MUIR, Engineer, 651 Gallowgate Street, Glasgow, do hereby declare the
nature of this invention to be as follows:-
This Machine consists of a Knife or Cutter mounted on a triangular Frame having
a stud fixed on one side, which carries a Lever with a long slot, which slot operates
on a stud fixed on centre of Knife or cutter carrier.
The Lever used for operating this Machine may be of any suitable length, and
operates at right angles to Machine; this places the operator in a more natural
position than any other like Machine constructed for such purposes.
This Machine is also pivoted in front of triangular Frame, which enables it to be
adjusted to any angle, so that all mitres simple or acute can be executed with ease and
expedition.
The range for Mitre Cutting by this Machine is practically unlimited.

page_text: I, ANDREW MUIR of 651 Gallowgate Street, Glasgow, in the County of Lanark,
North Britain, 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 an Improved Machine of simple construction, whereby
mitres or cuts of different angles can be executed with case and expedition; its
range for mitre cutting being variable according to the angle at which the Knife is
set;
another advantage being that when the Knife is set at right angles to the solo
plate, Battens, Boards, Architravos, or other Mouldings, may be faced dead square
with equal facility.
. On the annexed sheet of Drawings Figs. 1 and 2 are respectively a front and side
elevation, and Figure 3 a plan of the Machine with the Knife frame raised into the
vertical position, or at right angles to the sole plate n. Figures 4 and 5 are
respectively a front and side elevation of the Machine with the Knife at an angle of
45 to the plate n.

The frame is pivoted or
The Machine comprises a Knife or cutter a mounted on a
triangular sides 6 connected together at top by the bolt c.
hinged in front at e to the bed n. It can thus be folded back, and being provided
with a circular slot d (which may have graduated scale marked thereon) through
which projects the pin i; the frame b can be adjusted to any angle and kept thereat
by the handler on screw pin i and is also provided with an adjusting screw pin k as
shown at Fig. 5 for use to set and keep the Knife exactly at the 45° angle.
The bed or sole plate n has upright sides o from the highest part of which projects
the screw pin i. In the sides is a longitudinal slots Figs. 2 & 5 (the bottom of said
slot being on a level with the top of bed n) through which may be passed a piece of
wood which it is desired to cut diagonally. Fixed to one side of the frame 6 is a
stud t, on which is mounted one end of the operating lever u, having a long slot u¹
through which projects the stud v fixed on centre of Knife carrier.
The Lever may be of any suitable length and being operated at right angles to
Machine places the operator in a most convenient position for actuating it, and
handling the material to be cut. The machine may be fixed to, and with the top of
the sole plate on a level with, the top surface of a bench on which to lay flat the
material under operation, which is or may be most conveniently fed from behind the
machine.

page_text: 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. The arrangement and construction of the Machine as and for the purposes
hereinbefore described and illustrated.
2nd. In such Machines, a Knife or cutter carrying frame b, movable and adjustable,
so that the Machine may be capable of executing cuts of different angles substantially
as described and shown.
3rd. The particular combination in the particular manner, of the Handle u with
the other parts of Machine; which allows operator to work in a very convenient
position.
