I JOSEPH HAMILTON of 222 Burton Road Derby in the County of Derby, "Engineer"
do hereby declare the nature of my invention for "IMPROVEMENTS IN MACHINES FOR
SAWING AND FACING METALS, to be as follows:-
I use a main framing similar to a Lathe Bed, on which I mount a Saddle or Table,
which can be slid along (to and fro) by any mechanical arrangement. In bearings
upon the Saddle I mount a Spindle each end projecting beyond its bearing. The ends
being of suitable form I mount a circular saw at one end and disc with cutting
instruments at the other end.
At each side of the main framing I attach a block and upon each of the blocks,
I mount a Saddle, upon each Saddle I mount a Table or plate which is hinged to the
Saddle and is capable of being adjusted to various degrees of inclination transversely.
The table and Saddle being provided with means for adjustment transversely, Upon
the Tables the metal to be operated upon is firmly secured, The Spindle carrying the
Circular Saw, and Disc with cutting tools is caused to revolve in its bearings, and
together with the saddle is fed along the top of main framing. The Circular Saw
will commence sawing the metal to be operated upon, and the disc with cutting
instruments will commence facing the metal to be operated upon. The Tables and
Saddles having been adjusted to required distances from the faces of the Saw and disc,
Although I have mentioned only one Saw and one disc I do not confine myself to
same, It being competent to use either two Saws or two discs (i e) one of both kinds
at each end, as may be required.
Having thus described the nature of my Inventions and in what manner the same
are performed I claim
First the Construction of Machinery for Sawing and Facing Metals wherein the
Spindle carrying a Circular Saw, at one end is also made capable of carrying a
disc with cutting Instruments at reverse end substantially as herein described.
Second the Construction of Machinery for Sawing and facing Metals wherein the
Tables are adjustable to various degrees of Inclination transversely to the faces of the
Circular Saw and disc substantially as herein described.

Improvements in Machines for Sawing and Facing Metals.
I, JOSEPH HAMILTON of 222 Burton Road, Derby, in the County of Derby,
Engineer" do hereby declare the nature of my invention for "IMPROVEMENTS IN
MACHINES FOR SAWING AND FACING METALS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
I use a main framing similar to a Lathe Bed on which 1 mount a Saddle or Table
which can be slid along, to & fro, by any Mechanical arrangement, In bearings
upon the Saddle I mount a Spindle, each end projecting beyond its bearing, The ends
being of suitable form, I mount a Circular Saw at one end, and a Disc with cutting
instruments at the other end, At each side of the main framing I attach a block, and
upon each of the blocks I mount a Saddle. Upon each Saddle I mount a Table or
plate which is hinged to the Saddle and is capable of being adjusted to various
degrees of inclination transversely by means of Screws, or other mechanical arrange-
ments opposite the hinged sides (or at the ends) of the Tables. The Tables and
Saddles being provided with means of adjustments transversely.
Upon the Tables the Metal to be operated upon is firmly secured.
The Spindle carrying the Circular Saw and Disc with Cutting tools is caused to
revolve in its bearings, and together with the Saddle is fed along the top of the main
framing. The Circular Saw will commence sawing the Metal to be operated upon,
and the Disc with cutting instruments will commence facing the Metal to be
operated upon.
The Tables and Saddles having been adjusted to required distances from the faces of
the Saw & Disc, Although I have only mentioned one Saw and one Disc I do not
confine myself to same, It being competent to use either two Saws, or two Dises
(ie) one of both kinds at each end as may be required.

transverse adjustment of Saddles G, G¹, G2, Fig. 2 & 3-K. Fig. 1. is a Saddle
seperately adjustable transversely.
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 :-
First. The Construction of Machinery for Sawing & facing Metals wherein the
Spindle carrying a circular Saw at one end, is also made capable of carrying a Disc
with cutting instruments at reverse end, substantially as herein described.
Second. The Construction of Machinery for Sawing and facing Metals, wherein the
Tables are adjustable to various degrees of inclination transversely to the faces of the
Circular Saw and Disc substantially as herein described.
