PROVISIONAL SPECIFICATION.
A Sawing Machine for use in Forming the Parts of Iron Framing
and Joinery.
I, ANATOLE MÔLÉ of Laval (Mayenne) in the Republic of France Ironfounder
do hereby declare the nature of this invention to be as follows:-
My invention relates to a machine for use in forming the parts of iron framing
and joinery.
Hitherto the employment of a circular saw in the construction of iron frames
and the like has been found impracticable by reason of its inadaptability for
mitreing or cutting at an angle the different parts of iron frames and joinery. In
fact very large free spaces had to be left around the tool to be able to manoeuvre
the bars to be cut and to suitably present them to the saw.
In order to obviate these objections and allow of advantageously employing a
circular saw in making iron framing or joinery, I employ a machine in which a
circular saw is mounted in a frame which allows a deviation in two directions from
the ordinary position of a saw. The first is a deviation from the vertical plane of
the saw so as to allow of cutting at a variable angle the bars of round or other
section to be joined in order to form the frame and this I effect by arranging the
support of the saw so that it can pivot upon a horizontal axis. The second deviation
is caused by a movement of rotation upon a vertical axis of the box or case
containing the gearing which communicates the rotary movement to the shaft of
the saw.
The combination of these two movements allows of giving any required
position to the saw with relation to the piece of iron to be cut to form the framing
it being thus unnecessary to alter the position of the piece of iron to be presented
to the saw.

A Sawing Machine for use in Forming the Parts of Iron Framing
and Joinery.
I, ANATOLE MÔLÉ, of Laval (Mayenne) in the Republic of France, Ironfounder,
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:-
My invention relates to a sawing machine for use in forming the parts of iron
framing and joinery.
Hitherto the employment of a circular saw in the construction of iron frames and
the like has been found impracticable by reason of its inadaptability for mitreing
or cutting at an angle the different parts of iron frames and joinery. In fact very
large free spaces had to be left around the tool to be able to manoeuvre the bars to
be cut and to suitably present them to the saw.
In order to obviate these objections and allow of advantageously employing a

circular saw is mounted in a frame which allows a deviation of position in two
directions. The first is a deviation from the vertical plane of the saw so as to allow
of cutting at a variable angle the bars of round or other section to be joined in

which communicates the rotary movement to the shaft of the saw. The com-
bination of these two movements allows of giving any required position to the saw
with relation to the piece of iron to be cut to form the framing it being thus
unnecessary to alter the position of the piece of iron to be presented to the saw.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which:-
Figure 1 is a front elevation of a sawing machine constructed according to my
invention, for use in forming the parts of iron framing and joinery, the saw being
in the ordinary position.
Figure 2 is a plan, and,
Figures 3 and 4 are side elevations of the same.
Figure 5 is a similar view to Figure 2 but illustrating a horizontal deviation of
the saw.
Figure 6 is a section of a detail, and
Figure 7 is a similar view to Figure 4 but illustrating a vertical deviation of
the saw.
Similar letters in all the figures indicate similar parts.
The machine is constructed of a circular base A of the form of a truncated cone,
with its largest section resting on the ground, and having a step bearing a in the
centre of the bottom part.
The upper part of the base terminates in a flange and an interior annular rebate d
which serves as a guide to a cylinder B, the lower end of which is fitted in the
said annular rebate or guide d of the base A. This cylinder B which is hollow is
closed at its upper end beneath which is a socket or bearing h, receiving the vertical
shaft S having its other end resting in the step bearing a. The cylinder B has also
a flange corresponding to the flange c of the base on which it can thus turn with
slight friction. It can be fixed in any required position by means of bolts ß, ß,
securing together the flanges of the cylinder B and base A. To move the
cylinder B upon the base A I prefer to employ a worm e revolving in bearings f
on the base A and gearing with teeth g cast on the flange at the bottom of the
cylinder B.
ام
The top of the cylinder B is provided with two grooves at right angles to each
other. One of these grooves h is for the passage of the saw F and the other
groove k of V-shape serves to facilitate the holding of round or square iron bars
when placed normally to the groove h; to cut bars at other angles the cylinder B
is turned as shewn in Figure so as to give the saw the required inclination and
the bar is held by means of a plate a secured by bolts i the heads ; of which, as
shewn in Figure 6, (which is a section on the line m, n Figure 5) can be caused to
engage in circular grooves l, I which to this end are made with enlargements z.
Tangential to the cylinder B and cast therewith is a plate C the centre of which is
in a horizontal line with the lowermost part of the edge of the saw when the shaft
of the saw is horizontal.
The
A cylindrical casing D fits with its hollow part over the plate C which serves as
a guide thereto as shewn at m Figure 1; this casing D has on its exterior a boss n
for the passage of a shaft T and four ribs o, u, o, o uuited to the said boss.
shaft T, fixed to the plate by being screwed therein or otherwise, is screw-threaded
at its other end where it projects outside the casing D and serves by means of a
nutt to fix the casing with relation to the plate C when it has been adjusted to 5
the required position. The casing D is besides provided with two bearings p and q
through which passes a shaft U. On the ends of the shaft U is pivotted the saw
carrier E which is provided to this end with bearings r, s. The said carrier has an
arm V at the end of which is mounted a shaft Z which carries the circular saw or
cutter F; the vertical plane of the saw when in the normal or ordinary position as 5
shewn in Figures 1 and 2 intersects the axis of the groove / made in the cylinder B.
The arm V of the saw carrier is provided with a lever X which allows of

page_text: lifting the saw for placing in position a bar to be cut and of lowering it during the
cutting operation.
The machine is driven from a suitable motor through the medium of a shaft Y
on which are fast and loose pulleys G, G₁ and a bevel pinion H. This shaft Y
carried by the bearing J in the base A and by the bracket K fixed to the base
transmits its motion by means of another bevel wheel L to the vertical shaft S.
The shaft S communicates the motion by means of bevel gear M N to a shaft Y¹
carrying a helical gear wheel O driving a similar wheel P revolving loose upon the
shaft T. The helical gear wheel PP actuates the helical gear wheel Q placed at a
right angle thereto and mounted upon the shaft U. The shaft U carries another
helical gear wheel Q' which through the medium of the wheel R drives the shaft Z'
which revolves in the arm V of the saw carrier; this shaft Z' imparts the motion
to the shaft Z of the saw or cutter F by means of the worm u on the shaft Z' and
the pinion fixed on the saw-shaft Z.
With this construction I am enabled, by placing the piece of metal in the
direction of the line y Figures 2 and 5, to make any required cut therein. In the
first place by turning the cylinder B on the base A around the shaft S an oblique
position with respect to the line zy is given to the saw as shewn in Figure 5; in
the second place by moving the casing D with intermediate interior gearing on the
plate C around the shaft T, and by then tightening the nut t an oblique position
with respect to a vertical plane is given to the saw as shewn in Figure 7. By
adjusting the saw in these two directions any required cut can be easily made
without necessitating a large space around the machine.
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 :-
1. A sawing machine for use in forming the parts of iron framing and joinery in
which a circular saw or cutter is mounted in a frame which allows of adjusting the
saw or cutter to any required position in two directions, the adjustment in one
direction being effected by turning the machine upon a vertical shaft and in the
other direction by moving a casing supporting the saw-holder and containing the
gearing which imparts the rotary motion to the shaft of the saw or cutter,
substantially as hereinbefore described.
2. The improved sawing machine for use in forming the parts of iron framing
and joinery herein before described and illustrated in the accompanying drawing.
