Improvements in Rod Coiling Apparatus.
I JAMES JOHNSON of 4 Clayton Square Liverpool in the County of Lancaster
Patent Agent do hereby declare the nature of this invention to be as follows:-
My invention consists First, of a rod coiler which comprises a rotary cone having
at its upper end a hollow collar which may be conical in form and may encircle the
upper part of the cone. The collar and cone are connected by a rib or ribs
preferably two or more in number, which extend downwardly from the apex of the
cone in spiral lines and have lateral flanges projecting in the direction in which the
cone rotates. These ribs may be cast integrally with the cone and the collars.
The cone is rotatory on its vertical axis, the collar being journalled in a frame or
housing and provided with encircling gear teeth in gear with a pinion which may be
driven by a belt pulley or otherwise. The open upper end of the collar is situate
at the extremity of a guide trough or tube which leads from the rolls.
The operation is as follows:-The rod as it comes from the rolls passes through
the guide trough or tube and enters the open upper end of the collar and thence
passes down along the outer surface of the cone where it is engaged by one of the
ribs and as the rod is fed from the rolls the rib will distribute it in a regular coil
upon the receiving surface or around the usual drum below the cone, and the flange
on the rib will prevent the rod from escaping from the cone and tangling. The
advantage of using two ribs on the cone is that the rod is engaged more quickly than
if one only were used, but if desired there may be but one rib, and the ribs may
extend in straight line instead of spiral line.
Second, of a covered way which leads to the place in the mill where it is desired
to receive the coils for use or for preparation for shipment. The surface of this
way is preferably formed with parallel ribs and may incline upwardly to a down-
wardly inclined chute. Sprocket wheels are journalled in the way, one of them
being provided with suitable driving gear. A sprocket chain extends around these
wheels in a vertical plane and is provided at intervals with outwardly projecting
rods or spurs which are fixed to the chain links and which in the upper branch of
the chain, pass through a slot in the cover of the way. At or above this slot is a
track composed of upright parallel rails or flanges and the spurs are made of sufficient
length to extend above the same. In using the apparatus, the operator, who stands
at the coiler or coilers takes the rod coil with a hook or other instrument and places
it on the rails, over one of the passing spurs, or the same end may be attained by
placing it just over the rear of the sprocket wheel, so that the next spur in rising
through the slot will enter the coil. The coil then resting in an inclined position
on the rails and on the ribs, is pulled along the same until it reaches the chute,
where being released from the spur by the downward passage of the latter over the
sprocket-wheel, descends the chute to the mill floor. A material advantage is gained
by the use of the rails, since the coil is supported thereby in an inclined position
and is carried by the spur without such disarranging or tangling as would be apt
to occur were the coil dragged on its side along a flat surface. The great saving
of labor and the facility of operation afforded by my improved conveying device
will be appreciated by those skilled in the art and familiar with the difficult labor
heretofore required to remove the coils from the sub-floor or cellar in which they
are deposited by the coiler. The length of the sprocket-chain may be as great as
desired, and the coils therefore may be carried to any convenient part of the
rod mill

page_text: Third of a coiler which may consist of two concentric cones connected by an
intervening rib or ribs the outer cone being open at the top so that it may receive
the rod as it is delivered from the rolls. The coiler is supported in a suitable
housing, and is rotated on its vertical axis by proper gearing. The rod is delivered
from the rolls to and through the space between the cones through which it travels
in contact with the rib and is distributed in a coil upon a floor or platforın. In
order that the last end of the rod may be delivered from the cone when the rod has
lost its propulsive power by having passed through the rolls, I employ a drum
which is adapted to be raised within the circle described by the delivery end of the
coiler. So long as the rod is propelled by the rolls, it is distributed in a loose coil,
but when it has passed the rolls the rotation of the coiler wraps it around the drum,
and such wrapping by exerting tension on the rod, draws its end from the coiler.
If, in order to effect this result, the drum were raised within the limits of rotation of
the coiler proper, although this could be done, difficulty would be experienced in
causing the drum to enter the cone without making it of unduly small diameter,
and if the drum should not enter well within the limits of the coiler, there
would be a space in which the rod would be apt to be snarled. To prevent
this I employ a lip or projection which extends down from the rib below the
base of the cone for a considerable distance. After passing below the cone the
rod is guided by contact with this projection, and if the drum be raised so as
to be well within the limits of the circle described by rotation of the projection
the wrapping of the rod and drawing out of its last end will be effected without
difficulty. As this projection is apt to wear by friction of the rod I may make
it of a separate piece which is detachably set in position, and when worn can
be removed and replaced by another. This is of advantage even when the lip
does not extend below the end of the coiler, since the wear at the delivery end
of the present coilers, which rapidly spoils their utility, can be prevented by
inserting a removable piece against which the passing rod has a bearing.
order however to prevent wear of the parts as much as possible, I prefer to
employ an antifriction roller which is journalled at the rib at the lower end of
the coiler. The rod passes in contact with this roller which reduces the friction
and thus saves largely the abrasion which otherwise occurs with considerable
rapidity. The removable wearing piece or the antifriction roller may be applied
with benefit to tubular coilers or rotating coilers of various patterns.

Referring to the figures on Sheet 3, 17 are the rolls forming the last pass of
a rod mill, for rolling rods of iron or steel and 18 is the rod which passes
through the rolls in the direction of the arrow d. In advance of said rolls is a
rod coiler which comprises a rotary cone 19, having at its upper end a hollow
collar 20, which may be conical in form and may encircle the upper part of the
conc. The collar and cone are connected by a rib or ribs 21, preferably two
or more in number, which extend downwardly from the apex of the cone in
spiral lines and have lateral flanges 22, projecting in the direction in which the
cone rotates. These ribs may be cast integrally with the cone and the collar
as shown in Figure 12. The cone is rotatory on its vertical axis, the collar
being journalled in a frame or housing 24, and provided with encircling gear
teeth 25, in gear with a pinion 26, which may be driven by a belt pulley 27,
or otherwise. The open upper end of the collar 20, is situate at the extremity
of a guide-trough or tube 28, which leads from the rolls.
The operation is as follows:-The rod as it comes from the rolls passes through
the guide-trough or tube and enters the upper end of the collar 20, and thence
passes down along the outer surface of the cone 19, where it is engaged by one
of the ribs 21. The cone and collar rotate in the direction of the arrow e, and
as the rod is fed from the rolls, the rib will distribute it in a regular coil upon
the receiving surface or around the usual drum below the cone, and the flange
on the rib will prevent the rod from escaping from the cone and tangling. The
advantage of using two ribs on the cone is that the rod is engaged more quickly
than if one only were used, but if desired there may be but one rib, and the
ribs may extend in straight line instead of spiral line.
In this Specification I do not use the word "cone" in its strict mathematical
sense, but use it generically, meaning thereby a tapering body, whether it be
truly conical or not.
The other parts of my invention, illustrated on Sheets 2, and 3, relate to
mechanism for removing the rod after it has been coiled, and for preventing
wear on the coiler, caused by passage of the rod.
In Figure 1, 2, 2, represent a series of rotating conical coilers, each of which
may be connected by a guide-trough with one of the final roll passes. Unlike
the coiler shown in Sheet 3, the outer collar or cone, extends or may extend
to the base of the inner cone. I shall describe the construction of these rollers
more in detail with reference to the figures on the second sheet of the drawings.
Near the coiler is a covered way 3, which leads to the place in the mill where
it is desired to receive the coils for use or for preparation for shipment. The
surface of this way is preferably formed with parallel ribs 1, and may incline
upwardly to a downwardly inclined chute 4. 5, 6, are sprocket wheels journalled
in the way 3, one of them being provided with suitable driving gear 7. 8, is a
sprocket chain extending around these wheels in a vertical plane and provided at
intervals with outwardly projecting rods or spurs 10, which are fixed to the chain
links, as shown in Figure 3, and which in the upper branch of the chain, pass
through a slot in the cover of the way 3. At or above this slot is a track composed
of upright parallel rails or flanges 15, and the spurs are made of sufficient length to
extend above the same. 9, 9, are rollers by which the upper branch of the chain is
supported. In using the apparatus, the operator, who stands at the coiler or coilers,
takes the rod coil with a hook or other instrument and places it on the rails 15, over
one of the passing spurs 10, or the same end may be attained by placing it just over
the rear of the sprocket wheels 5, so that the next spur in rising through the slot

page_text: will enter the coil. The coil then resting in an inclined position on the rails and on
the ribs 1, is pulled along the same until it reaches the chute 4, where being released
from the spur by the downward passage of the latter over the sprocket wheel 6,
descends the chute to the mill floor. A material advantage is gained by the use of
the rails 15, since the coil is supported thereby in an inclined position and is carried
by the spur without such disarranging or tangling as would be apt to occur were
the coil dragged on its side along a flat surface. The great saving of labor and the
facility of operation afforded by my improved conveying device will be appreciated
by those skilled in the art and familiar with the difficult labor heretofore required
to remove the coils from the sub-floor or cellar in which they are deposited by the
coiler. The length of the sprocket chain may be as great as desired, and the coils
therefore may be carried to any convenient part of the rod mill.
I shall now describe the construction of my improved coiler, which is illustrated
in detail in Figures 4, 5, 6, and 7.
The coiler may consist of two concentric cones b, c, connected by an intervening
rib or ribs 11, the outer cone being open at the top so that it may receive the rod
as it is delivered from the rolls. The coiler is supported in a suitable housing, not
shown, and is rotated on its vertical axis by proper gearing. The rod is delivered
from the rolls to and through the space between the concs-through which it travels
in contact with the rib 11, and is distributed in a coil upon a floor or platform 2.
In order that the last end of the rod may be delivered from the cone when the rod
nas lost its propulsive power by having passed through the rolls, I employ a drum 13
which is adapted to be raised within the circle described by the delivery end of the
coiler. So long as the rod is propelled by the rolls, it is distributed in a loose coil,
but when it has passed the rolls, the rotation of the coiler wraps it around the drum,
and such wrapping by exerting tension on the rod, draws its end from the coiler.
If in order to effect this result, the drum were raised within the limits of the rotation
of the coiler proper, although this could be done, difficulty would be experienced in
causing the drum to enter the cone without making it of unduly small diameter, and
if the drum should not enter well within the limits of the coiler, there would be a
space in which the rod would be apt to be snarled. To prevent this I employ a lip
or projection 14, which extends down from the rib 11 below the base of the conc
for a considerable distance. After passing below the cone the rod is guided by
contact with this projection, and if the drum be raised so as to be well within the
limits of the circle described by rotation of the projection, the wrapping of the
rod and drawing out of its last end will be effected without difficulty. As this
projection is apt to wear by friction of the rod, I may make it of a separate piece
which is detachably set in position as shown in Figures 4 and 5, and when worn can
be removed and replaced by another. This is of advantage even when the lip does
not extend below the end of the coiler, since the wear at the delivery end of present
coilers, which rapidly spoils their utility, can be prevented by inserting a removable
piece against which the passing rod has a bearing. In order, however, to prevent
wear of the parts as much as possible, I prefer to employ an antifriction roller 16
(Figs. 6 and 7) which is journalled at the rib at the lower end of the coiler. The
rod passes in contact with this roller which reduces the friction and thus saves
largely the abrasion which otherwise occurs with considerable rapidity. The
removable wearing piece or the antifriction roller may be applied with benefit to
tubular coilers or rotating coilers of various patterns.
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. In apparatus for coiling rods, the combination with the rolls, of a rotary
receiving and coiling cone, having a channel which receives the rod at the smaller
end and delivers it at its base.
Second. In metal coiling apparatus, a rotary coiling cone, having a longitudinal
rib with a lateral flange.

page_text: Third. In metal coiling apparatus, a rotary coiling cone, having two longitudinal
ribs with lateral flanges.
Fourth. In metal coiling apparatus, a rotary coiling, cone, having an exposed
outer surface, along which the rod travels, a hollow collar and driving gear.
Fifth. In a rod-coiler, the combination of a coiling channel rotatory in a circular
course and having a lip projecting below its end and a drum movable within the
limit of rotation of the lip to cause removal of the last end.
Sixth. In a rod-coiler, a rotatory coiling-channel having a removable wearing
piece or lip at its delivery end.
Seventh. In a rod coiler, the combination with a rotatory coiling channel, through
which the rod passes and by which it is distributed in a coil, of a roller at the delivery
end of the channel.
Eighth. The combination with a rod coiler of a continuously travelling carrier
leading therefrom.
Ninth. The combination with a rod coiler, of an endless chain having spurs
projecting between elevated rails 15 forming a track on which the coil may
ride.
Tenth. The combination with a rod coiler, of an endless carrier chain leading
therefrom and having spurs for engaging the coils, driving wheels for the chain, and
a chute at the final driving wheel.
