I, NICOL ARTHUR of 11 North Fort Street, Leith, in the County of Midlothian,
Shipbuilder, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR SETTING AND BEVELLING ANGLE, TEE, AND OTHER
METAL BARS, AND FOR FLANGING PLATES to be as follows:-
"
This Invention relates to improvements in machinery or apparatus for setting
over and bevelling or altering the angle of angle iron, tee, channel, and other
metal bars, that is to say, of altering the sides webs, or flanges from their
manufactured position to any other desired angle to suit the special purpose for
which the bar is to be used.
The improved machine or apparatus is also applicable to be employed in flanging
iron, steel, or other metal plates, and as shewn in side elevation partly in section,
at figure 1, in plan at figure 2, and in end elevation at figure 3, the apparatus
consists of end frames A, connected together by side frames B, and mounted on
wheels C.
In the framing a shaft D, is carried in blocks E, supported on screws F, for
adjustment by the hand wheel a, on one end of a spindle b, carried in brackets c,
secured to one of the end frames A, On the shaft b, is a spur pinion d, geared with
a spur wheel e, fixed towards the lower end of one screw F, Below the wheel e,
and also on the screw is a bevel wheel f, geared with a similar wheel f', on a
shaft g; and on the opposite end of the said shaft another bevel wheel h, gears. with
a wheel h¹, on the lower extremity of the other screw. F.
The shaft D, is screwed throughout a portion of its length and on the screwed
part a couch roller G, is carried being keyed thereto by the feather j, or equivalent
means, and to the nut i, by horns k.
By this arrangement whilst the roller G, receives rotary motion from the shaft D,
it is also capable of adjustment horizontally.
The circumference of the roller G, is stepped.
The shaft D, is rotated by the spur wheel H, geared with a pinion I, on a stud J,
carried in one of the end frames A, and on the said stud another wheel K, is secured
and geared with a pinion L on the main or driving shaft M, actuated manually by
a crank N, or by power as desired. In the latter case a belt pulley is substituted
for the crank, or a small engine is or may be attached to the end frame A.
In conjunction with the couch roller G, a series of rollers are employed to effect
the setting over and angling or bevelling of the bars. These rollers consist of the
roller R, carried on a stud R'.
i
The roller R, receives rotary motion from a worm wheel m, on the stud R¹,
actuated by a screw on a spindle n, and whereon a pitched chain or sprocket
wheel o,
is also keyed through which the spindle is rotated by an endless pitch

page_text: chain o¹, passed round the said wheel o, and round another sprocket wheel p, on
one end of a shaft Q, rotated by an endless pitch chain r, passed round a sprocket
wheel r¹, on the said shaft Q; and round a sprocket wheel, on the driving
shaft M, or any other equivalent arrangement of driving the shaft Q, at equal speed
with the roller G, may be substituted.
At an angle to the roller R, other rollers O, T, are placed the roller O, being
centered on a stud P, in a saddle S, carried in quadrant grooves or bearings S¹,
whilst the roller T, is carried by a nut t, on a screwed stud T¹, by which means it
is capable of adjustment to a greater or less distance from the roller O, as may be
required.
The rollers O, T, are also capable of being adjusted in unison relatively with the
rollers G, and R, by the hand wheel U, and screw U', secured by the frame V, to
the saddle S, and in order that this adjustment may be effected with accuracy a
frame W, extends between the end frames A, and on which an index board W¹, is
carried whereon the angles are laid off as indicated by the dotted lines figure 1.
An indicator arm w, is attached at its lower end to a frame V, and at-its upper
end formed with a curved slot through which a pin is passed into the frame W,
Thus when the saddle S, is drawn to the left the indicator arm w, is inclined, the
inclination of the rollers O. T, relatively with the couch roller G, being easily seen
from the lines on the board or index W¹.
The machine is also applicable to be used for flanging iron, steel, or other metal
plates, and to facilitate the passage of the bars or plates through the machine other
couch rollers besides the roller G, are or may be provided. One of these rollers Z,
is situated at the entrance side of the machine on the shaft Q, which is rotated
as herein before stated from the main or driving shaft M.
The other couch roller Z¹, is situated on a shaft y, and is rotated by the endless
pitch chain y, passed round the chain or sprocket wheel y², and also round a
similar wheel y³, on the corresponding end of the shaft D.
This roller Z', is provided with flanges at its ends, by which means the bar may
be set or curved as it passes through the machine, the roller Z', being capable of
adjustment horizontally as hereinbefore described with reference to the couch
roller G.
On the shaft y, a drum or barrel 1, is or may also be secured, to assist in drawing
the bars or plates through the machine several turns of a chain being taken round
the drum or barrel, whilst an end of the chain is secured to the bar or plate to be
operated upon as it comes from the heating furnace.
To indicate the length or number of feet of bars or plates operated upon an index
dial 2, is or may be provided, and actuated from a worm screw 3, on the shaft D,
geared with a worm wheel 4, on the lower end of a vertical spindle 5, which at its
upper end has a bevel wheel geared with a similar wheel on the end of the
horizontal spindle on which the index finger or pointer 6, is situated or the said
indicator may be actuated from any other convenient moving part of the machine.
The finger or pointer 6, is or may be secured to its spinale by a thumb nut in
order that it may be slackened and so prevented from going back when at any time
it may be necessary to reverse the direction of motion of the shaft D, or the said
pointer may be rendered stationary by a clutch on its spindle, or on the vertical
spindle 5, or by other equivalent means.
The rollers Ŏ. R, instead of being arranged as shewn at figure 1 may be arranged
as at figure 4.

page_text: Í, NICOL ARTHUR of 11 North Fort Street Leith in the County of Midlothian
Shipbuilder, do hereby declare the nature of the said Invention for "IMPROVE-_
MENTS IN MACHINERY OR APPARATUS FOR SETTING AND BEVELLING ANGLE, TEE,
AND OTHER METAL BARS AND FOR FLANGING PLATES 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 machinery or apparatus for setting
over and bevelling or altering the angle of angle iron, tee, channel, and other metal
bars, that is to say, of altering the sides, webs, or flanges from their manufactured
position to any other desired angle to suit the special purpose for which the bar is
to be used.
· The improved machine or apparatus is also applicable to be employed in bending
iron, steel, or other metal plates.
And in order that the said Invention may be properly understood I have
hereunto appended an explanatory sheet of drawings illustrative of the system,
mode, or manner in or under which it is or may be used. Figure 1, being a
vertical section; figure 2, a plan; and figure 3 an end elevation of the machine.
As shown by these figures the apparatus consists of end frames A, connected
together by side frames B, and mounted on wheels C, on which it is capable of
being traversed from one position to another.
In the framing a shaft D, is carried in blocks E, which are capable of vertical
adjustment in guides made in the end frames A, and are for that purpose supported
on screws F, the adjustment being effected by the hand wheel a, secured on one
end of a spindle b, carried in brackets c, bolted to one of the end frames A, as seen
at figure 1. On the spindle b, a spur pinion d, is keyed and geared with a spur
pinion e, fixed on one end of a horizontal shaft g, carried in the lower parts of the
end frames A, On the lower end of each screw F, a worm wheel h, is secured and
geared with a worm screw f¹, fixed on the shaft g.
The shaft D, is screwed throughout a portion of its length and on the said
screwed part a sleeved nut i, figure 1, is placed. A couch roller G, is also carried
on the shaft D, being keyed thereto by the feather j, or other equivalent means
and also to the nut i, by the horns k, which are bolted to the end of the roller G,.
and have projections entering a circular groove made around the nut.
P
By this arrangement whilst the roller G, receives rotary motion through the
feather j, from the shaft D, it is also capable of adjustment horizontally on the shaft
such adjustment being effected when desired on turning the sleeved nut i, by means
of handles or spokes ¹, with which it is provided.
The circumference of the roller G, is stepped as seen at figure 1, for a purpose
hereinafter referred to.
The shaft D, is rotated by the spur wheel H, geared with a pinion I, fixed on
a shaft J, carried in one of the end frames A, and in a bracket J¹, and on the said
shaft another wheel K, is secured and geared with a pinion L, fixed on a shaft M,.
which is the main or driving shaft of the machine and is actuated by steam or other
motive power applied to a crank disc N, or manually as desired.
In conjunction with the couch roller G, a series of rollers are employed to effect
the setting over and angling or bevelling of the bars. These rollers consist of the
roller R, carried on a stud R', supported top and bottom in cross frames P¹, P³,
extending between the two sides of one of the frames A.

page_text: S
The roller R, bas rotary motion communicated to it from the shaft D, through
the bevel wheels m, n, one of which is secured on the shaft D, and the other
carried on a feather on a vertical spindle O¹, which at its upper end is supported
in the cross frame P³, and at its lower end in a footstep bracket r, secured to the
end frame A.
On the upper end of the spindle O¹, a spur pinion n¹, is fixed and geared with
a corresponding wheel m¹, fixed on the stud R¹ To cause the wheels m, n, to
remain in gear during the raising and lowering of the shaft D, the wheel n, is
seated in a bracket p¹, which is secured to and rises and falls with the block E.
The gearing m, n, m³, n¹, is so proportioned as to rotate the roller R, with the
same surface velocity as the roller G.
At one angle to the roller R, another roller O, is centred on a stud P, supported
in a frame or saddle S, carried in quadrant grooves or bearings S', in the side
frames B, as seen at figore 1.
The roller O, is adjusted relatively with the rollers G, and R, according to the
set or bevel it is desired to give to the bars passing through the machine. This
adjustment is effected by the hand wheel U, and screw U₁, on one end of which
the said hand wheel is fixed whilst its other end is secured by the frame V, to the
saddle S, The screw U¹, passes through a nut or screwed sleeve x, and by turning
the hand wheel U, the saddle S, is moved and adjusted in the quadrant guides or
bearings to the desired position.
In order that this latter adjustment may be effected with accuracy a frame W,
extends between the end frames A, and on the said frame W, an index-board W¹,
is carried on which the angles are laid off.
An indicator arm w, is attached at its lower end to the frame V, and at its
centre formed with a slot through which a pin is passed into the frame W. Thus
when the saddle S, and with it the roller O, is drawn to the left the indicator
arm w, is inclined in the opposite direction the amount of inclination and con-
sequently the inclination of the roller O, relatively with the rollers G, R, being
easily seen from the degrees of angles on the board or index W¹.
Besides the rollers hereinbefore referred to other rollers Y, Z, are used in the
machine as shown. The rollers Y, are centred loosely on studs 8, carried by the
brackets J, J, the upper ends of each of which are bolted to the side frames B,
whilst their lower ends are carried by shafts X, X¹, extending from one end frame A,
to the other. The upper end of each stud s, has a block s¹, formed on or secured
to it, which enters a recess or guide 82, made in projections formed on a beam T,
extending from one side frame B, to the other. As seen by the detail view
figure 4, these recesses or guides are inclined in a horizontal frame and their upper
surfaces constitute an arc with the radius 8², u, figure 1. The blocks 8', are
connected together by a link U one block being also connected by a link piece U',
to a screw t, working through a sleeve t¹, made on one side frame B. The lower
ends of the studs 8, work in slotted holes made in the bracket J¹, J, and they
are retained in position by a pin u, around which they are free to move through an
are. By this arrangement and by linking the studs s, together as above set forth
the adjustment of the rollers Y, by means of the screw t, is rendered. uniform.
The rollers Z, are carried on studs v¹, which at their lower extremities are formed
with eyes through which the shafts X, X', pass and at their upper ends they are
supported in brackets k, bolted to the side frames B. The holes in these brackets
through which the studs v³, pass are slotted as seen at figure 2, to permit of
adjustment of the rollers Z, to a greater or less distance from the centre of the
.machine.
The rollers Z, are used in conjunction with couch rollers Q, Q¹, One of these
rollers Q, is situated at the entrance side of the machine on the shaft X, on which
it is capable of adjustment after the manner of the roller G, The shaft X, is
rotated from the shaft D, by an endless chain passed round sprocket
which ¹, is situated on the shaft D, and the other 2, on the shaft X,
is the same diameter as the greater diameter of the roller G, and
wheels one of
The roller Q,
the sprocket

page_text: wheels x1, x2, are of equal diameter so that the rollers G, Q, rotate with the same
surface velocity.
The other couch roller Q¹, is situated on the shaft X, at the delivery side of the
machine and is driven by friction.
Between the rollers G, Q¹, another couch roller y', figure 2, is carried on a
shaft Y, the inner end of which is borne by the bracket J, and its outer end by the
frame P, The roller y¹, is formed with a flange similarly with the rollers G, Q,
and it is adjusted relatively with them by screwing the outer end of the shaft y,
and operating it by the nut y³. To assist in drawing the bars or plates into or
through the machine a drum or barrel y', is secured on the end of the shaft D, and
as the bar or plate comes from the heating furnace a chain is connected to the end
of it and passed through the space between the rollers G, O, Y, to a snatch block
or pulley in front of the machine from whence it is led to and wound on the
barrel y, so that when the shaft D, is set in motion the bar is dragged forward by
the chain.
In order to indicate the number of feet of bars or plates operated on, an index
dial 2, is or may be provided. This dial is actuated from a worm screw 3, fixed or
formed on the shaft D, as at figure 2, and geared with a worm wheel 4, on the
lower end of a vertical spindle 5, which spindle at its upper end has a bevel wheel
geared with a similar wheel on the end of the horizontal spindle on which the
index finger or pointer 6, is situated or the said indicator may be actuated from
any other convenient moving part of the machine.
The finger or pointer 6, is or may be secured to its spindle by a thumb nut so
that it may be slackened and prevented from going forward until the bar has
entered the machine or the said pointer may be rendered stationary by a clutch on
its spindle or on the vertical spindle 5, or by other equivalent means.
•
In operating with the machine to alter the angle of a bar, the bar is fed through
the machine preferably in a direction slightly angular to the transverse axis of the
machine as indicated by the heavy dotted line on figure 2, as it is found that this
prevents the bar from riding. To provide for and regulate this angular feed the
roller Z', is set slightly in advance of the roller O, In altering the angle to an obtuse
angle one flange of the bar passes between the periphery of the roller G, and the
under surface of the roller R, the rollers G, Z, Z, being previously adjusted to
the thickness of bar being operated upon. The back of the angle rests against the .
projecting part 7, of the roller G, and the inner part of it is acted upon by
the part 8, of the roller O, and according to the position of the roller O, so is the
vertical flange bent over to the angle required throughout or at any required part
in the length of the bar.
The rollers Z, Z, guide the bars and prevent any tendency to twist or warp.
They also act to straighten or slightly set the bars as may be required.
In altering the angle to an acute angle the horizontal flange passes between the
rollers Y, and the wider part of the roller G, and the back of the vertical flange is
acted upon by the roller O, the rollers Y, G, being previously adjusted to the
thickness of bar being operated on. Manifestly lengths of the same bar may be
bent to different angles by the machine at one operation.
In flanging plates one part.passes above the rollers Y, and the other part between
the rollers R, G.
It is to be understood that I do not confine myself to the precise arrangement of
rollers hereinbefore described and shown on the drawings as that arrangement may
be varied without departing from the main or essential feature of my invention
which is the application and use of rollers relatively adjustable for the purposes set
forth.
.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is,
First The general arrangement and combination of parts constituting the
machine for setting and bevelling angle, tee, and other metal bars and for flanging

page_text: and bending plates substantially as herein before described with reference to the
drawings annexed or any mere modification thereof.
Second For setting and bevelling angle, tee, and other metal bars and for
flanging plates the application and use of a series of rollers relatively adjustable
and whereby a different angle or bevel can be given to different parts of the bar or
plate fed through between the rollers either by the machine itself or by other
means.
Third In a machine for the purposes set forth the combination of rollers G, R,
O, Y, Z, Q, and y¹, arranged and operating substantially as herein before described
with reference to the drawings annexed or any mere modification thereof.
..
Fourth In a machine for the purposes set forth the combination of the roller O,
saddle S, quadrant guides S¹, frame V, screw U¹, and indicating board W₁,
substantially as and for the purposes herein before described with reference to the
appended drawings or any mere modification thereof.
Deted this Taronty fourth day of October 1884.
