Patent.
'
NOW KNOW YE, that we, the said John Octavius Butler and
Ambrose Edmund Heath Buckley Butler, do hereby declare the nature
of our said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following
statement (that is to say) :—
Our Invention relates partly to the machinery for rolling, straightening,
and finishing bars or tubes of iron and other metals, for which Letters
Patent were granted to James Robertson, on the 20th day of December
1869, Number 3677, and to George Walter Dyson and Henry Arthur
Hall, on the 31st day of October 1870, Number 2856, and it consists in the
5 addition of an adjustable table to each side of the rolls or discs described
in the Specifications of the said Patents, the object of which tables is to
support the bar or tube that is being operated upon. The level of
these tables is regulated according to the diameter of the bar or tube
.

page_text: under operation by means of screws or other equivalents. These
adjustable tables are also applicable to other machinery for rolling,
straightening, and finishing bars and tubes.
Also in the application of a windlass or other suitable apparatus for
feeding the bars or tubes to the machinery for rolling, straightening, and
finishing.
Another part of our Invention consists in applying to machinery for
rolling, straightening, and finishing bars or tubes, a table or rocking
frame on which the bars or tubes are placed on leaving the machine, and
on which they are kept revolving while cooling to prevent warping and
to keep them true.
The rocking frame consists of a series of bars, the ends of which are
raised alternately to cause the bars or tubes to roll to and fro, or the
rocking frame may oscillate on a centre, or the rolling motion may be
obtained by friction or otherwise.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying two
Sheets of Drawings, reference being had to the figures and letters marked
thereon.
On Sheet 1 Fig. 1 is an elevation, and Fig. 2, a plan; and on Sheet 2 :
Fig. 3 is a side view of a machine for rolling, straightening, and finishing
bars and tubes of iron and other metals to which our improvements are
applied.
Fig. 4 is an end view of the adjustable tables; Fig. 5 is an elevation;
and Fig. 6, a plan of the connection between the said tables.

A and B are the axles of the two discs C, D, which are similar to
those described in the Specifications of the Patents granted to James
Robertson, and George Walter Dyson, and Henry Arthur Hall, above
referred to. Both the axles A and B are driven from the main shaft E,
on which are keyed the broad wheels e¹, e³, gearing into the wheels a¹ 3
and 6', fixed on the axles A and B. In the Patents above referred to
only one of the discs was provided with gearing for moving it to and fro
laterally, so as to vary the distance between the faces of the discs,
according to the diameter of the bar or tube under operation. Now in
order to render the machine more complete and better adapted to our §

page_text: improvements, we connect both the axles A and B by the following
gearing, so that both discs are moved laterally to and fro simultaneously,
thereby keeping the axis of the bar or tube in the same line. To the
cross shaft fare fixed the pinions ƒ¹ and ƒ³, and the hand wheel f' by
3 which the shaft is turned round; each pinion gears into a carrier wheel
for transmitting motion to the wheels a² and 6%, which are fixed on
screws, the ends of which are connected to sliding blocks acting on the
ends of the axles A and B.
In order to support the bar or tube during the operation of rolling,
2 straightening, and finishing, we apply to each side of the discs O and D
a long table F, the level of which can be varied according to the
diameter of the bar or tube under operation, so that the axis of the bar
or tube can be kept in any horizontal plane parallel to, and either above
or below the axis of the discs. Each table F is secured to the bed G,
and as the face of the discs C, D, is slightly tapered as shewn in Fig. 2,
the tables and beds are set at a corresponding angle to a line drawn at
right angles to the axes of the axles A and B. At each side of each
table are three or other convenient number of V shaped grooves fitting
in the guides H, which are supported by the frames I as shewn best in
Fig. 4. The guides can be set up by regulating screws. In the beds G
are fixed screw nuts for the vertical screws J, and at the lower end of
each screw is keyed a worm wheel j; all these worm wheels are turned
round simultaneously by the worms k on the side shaft K, which is
driven by gearing from the main shaft E in the following manner :- -On
the shaft E are mounted loose the mitre wheels e, e, to each of which is
cast a friction box, as shewn in Fig. 2; between these friction boxes is
the double friction cone e³ which is connected to the shaft E by a key
and groove, and by moving the cone e³ into contact with the friction
box on either of the wheels e, the direction of rotation of the screws J.
can be reversed, both the wheels e gear into a similar wheel e' on the
shaft e³, and this shaft is connected by bevel wheels, and a short
diagonal shaft to the side shaft K. By this arrangement the tables F
can be raised or lowered simultaneously.
We do not confine ourselves to obtain the rising and falling move-
ment of the tables in the manner above described. The screws J may
be worked independently of the rest of the machine, or the move-
ment may be obtained by steam or hydraulic power, or by other
means.

page_text: In Figs. 5 and 6 we have shown how the bar or tube under operation
is supported between the ends of the tables F. To each bed G is bolted
a bracket I, and the cross rail g' fits on projections cast to these brackets.
The under side of the cross rail is bevel to fit the wedge 9ª, which is
provided with a screw and nut to move it endwise. When the wedge b
is moved in the direction of the arrow in Fig. 5 it raises the cross rail,
and the contrary action takes place when the wedge is moved in the
opposite direction; by this means the level of the cross rail can be
regulated.
The adjustable tables above described are applicable to other machinery 1
for rolling, straightening, and finishing bars and tubes.
Our Invention consists also in the application of windlasses or other
suitable apparatus for feeding the bars or tubes to and removing them
from machinery for rolling, straightening, and finishing.
Figs. 7 and 8 represent an elevation and plan of our machinery for 1
imparting a revolving motion to the bars or tubes while cooling to
prevent them warping. The apparatus consists of two or more tables L
placed at any convenient distance apart, and fitting in grooves in a bed
plate. The tables are supported on antifriction rollers, and are moved
to and fro by cranks on the main shaft M. These cranks are connected 2
by the links m to the vibrating lovers m³, the upper ends of which pass
through slots in the guide rods of the tables L, or the to-and-fro
motion be obtained in any other convenient manner. The bars or
tubes to be operated upon are laid on the bed plate and the pegs & are
inserted into the tables L to keep the bars or tubes apart; the to-and-fro 2
motion of the tables then causes the hot bars or tubes to revolve
while cooling alternately in contrary directions, thereby preventing
warping.
may
This apparatus may be modified by placing the tables Labove the
bars or tubes, and inverting the position of the pegs . Or the revolving a
motion may be communicated to the bars or tubes by means of a rocking
frame, consisting of a series of bars mounted on a fixed centre, the ends
of which are raised and lowered alternately to cause the bars or tubes
to roll to and fro; or the rolling motion may be obtained by friction or
otherwise.
Having thus described the nature and particulars of our Invention,
we declare that we claim,—
3

page_text: First. The application of tables to machines for rolling, straightening,
and finishing bars and tubes, as shewn and described.
Secondly. Regulating the level of the said tables, as shown and
described.
Thirdly. The application of windlasses or other equivalents to machines
for rolling, straightening, and finishing bars and tubes, for the purposes
described.
Fourthly. Imparting a revolving motion alternately in contrary
directions to the bars or tubes after they have been rolled, straightened,
and finished by the machinery above referred to, or any other machinery,
as shewn and as described.
And, lastly. The machinery described and shewn in Figs. 7 and 8, or
any modification of machinery for imparting a revolving motion in
contrary directions to bars and tubes when cooling.
In witness whereof, we, the said John Octavius Butler and
Ambrose Edmund Heath Buckley Butler, have hereto set our
hands and seals, this Third day of April, One thousand eight
hundred and seventy-six.
