COMPLETE SPECIFICATION.
Improvements in Reeling Apparatus for Rod Rolling Mills.
I, FRED HARRIS DANIELS of Worcester in the County of Worcester and State
of Massachusetts, United States of America, Mechanical Engineer, 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 :-
The object of my present invention is to provide a reeling apparatus for coiling
wire rods or similar rolling-mill product as it is delivered from the rolling mill which
apparatus is provided with reeling: devices capable of being tilted, and efficient
mechanism for conveniently swinging or oscillating the reel-supporting frame for
carrying the coil-receptacle; or reel-head, from the position at which it receives the
rod to another position for facilitating the convenient removal or discharge of the
coiled rod therefrom.
Another object is to provide means for stopping the rotation of the reel when tipped
for discharging, and for starting and operating the same when returned to coiling
position.
Another object is to provide a brake mechanism that is automatically brought into
action for stopping rotation of the reel when the supporting frame is tilted.
These objects I attain by mechanism, the nature, construction, and operation of
which is clearly explained in the following description, and shown in the accom-
panying drawings, the particular subject matter being hereinafter definitely specified.
In the drawings:-
Fig. 1 is a front view of my improved rod-reeling apparatus, the guard or top
casing being shown in section.
Fig. 2 is a plan view of the same.

page_text: Fig. 4 is a horizontal section at a position just below the reel-head or coil
receptacle.
b
Referring to the different parts, A denotes the reel-head or coil-receptacle,
preferably composed of a plate having a series of upright pins or spokes a of usual
construction, or with suitable rims, for defining an annular space within which the rod
is coiled as it is delivered thereto from the rolling-mill through the guide pipe R.
Said reel or coil-receptacle is supported on a rotable shaft A' that is provided with
an operating gear or friction-wheel C, and is mounted in bearings 6 on an oscillating
or tipping frame B; which frame is provided with an axial support or trunnions B¹
that rest in bearings on the main supporting frame D, in a manner to permit of said
tipping-frame B together with the reel A, being tilted or tipped down, as desired, to
effect or facilitate the discharge of the coiled rod therefrom in the manner shown by
dotted lines in Fig. 3. The tipping frame B is provided with a segment B2 that
engages by means of gear-teeth or other suitable connecting devices, with a recipro-
cating bar or rack E mounted in suitable guides G to operate back and forth, and
preferably connected with a piston and piston-rod F which is worked by hydraulic or
other pressure exerted in the cylinder F under control of any suitable and convenient
valve mechanism, such as ordinarily employed for controlling the action of hydraulic
piston-mechanism, and which valve mechanism being well known is not herein shown.
Cindicates a revoluble friction-wheel mounted on an upright shaft C that turns in
suitable bearings on the supporting frame. Said wheel meshes with the reel-
operating wheel C.for imparting movement to the reel. The wheel (" is connected
by suitable gearing I, with a driving shaft H, that is in turn operated by gearing H¹
from the rolling-mill, or from any convenient motor. Or any of the usual well known
means for mechanically transmitting power may be employed for imparting motion to
the shaft C². The wheels C and C are preferably made with ribbed frictional
surfaces, (but other forms of surfaces may be employed if desired) to engage with each
other, and transmit the power and motion to the reel-shaft when their surfaces are
brought together with sufficient force.
J.indicates a brake-arm carrying a suitable bearing-shoe J arranged to press against
the surfaces of the wheel C for stopping the rotation of the reel when the wheels C
and Care.separated. The brake-arm J is connected with the frame B at one side by
a hinge or other suitable connecting joint; as at K, while its opposite end is connected
by a link to the upper end of a lever L that is fulcrumed upon the frame B, as
indicated at m. The dependent arm of said lever L is made heavy, or is provided with
a weight L', and said lever is arranged in such manner that when the frame is tilted
the weighted end of said lever is swung upward, and the counterpoise of the weight
forces the brake against the surface of the wheel C, the pressure being applied
thereto in a gradually increasing degree accordingly as the lever assumes a more
nearly horizontal position. A stop or guard M is provided to engage the lever L
and prevent contact of the brake with the wheel C when the reel is upright or in
normal working position.
The reel is surrounded by a guard-cylinder or casing N, having at one side an
extension N¹ to permit of the reel being tilted over. Said casing is provided with a
removable cover N2, as indicated.
PP indicates curved guides for the upper part of the frame B to support it laterally
and keep it steady when in working position, and while being tilted. The axis of
the frame B is, in the present instance, located some distance in the rear of the
vertical axis of the reel-shaft A¹ in order that the reel may have a more ready and
direct drop from its casing or guard, when the tilting action is effected, than it would
were the axes in the same plane.
In the operation of the mechanism the rod is delivered to and coiled upon the reel
while it is in upright position. The reel is then lowered and brought into position
to facilitate the convenient discharge of the coiled rod therefrom by tilting or
tipping the frame B whereon the reel is mounted into the position shown-in dotted
lines in Fig. 3. This tipping action is effected by drawing back the rack-E by the

page_text: hydraulic piston which swings the segment B with a corresponding backward
movement, and lowers the reel or coil-receptacle containing the coil of rod, so as
to present the coil at a position where it can be conveniently hooked off, gripped
by tongs, or otherwise removed, as desired.
If desired, in lieu of using the reciprocating rack E, the segment B2 could be made
as a worm-wheel and the frame be operated by a worm-screw meshing therewith;
the worm-screw being mounted upon a rotating shaft located in place of the
piston-rod and rack, and operated by belts and pulleys or other equivalent means.
This latter method of operating the tipping-frame might be employed in cases where
it would be inconvenient to employ hydraulic mechanism such as a cylinder and
piston.
It will also be understood that instead of connecting the segment B2 and recipro-.
cating bar E by means of teeth, these parts could be connected by straps or chains,
or other well known mechanical devices for effecting equivalent movement. Again,
if desired, the piston-rod F could be attached by a connecting link, directly to a.
wrist-pin on the side of the segment B2, or to an arm of the frame B to act in the
manner of a crank. I prefer, however, the construction shown as being the more
simple and satisfactory.
When the reel is in operation, the friction surfaces of the wheel C are forced
against that of the wheel C by the pressure exerted in the hydraulic cylinder F¹;
hence an amount of pressure can be applied for giving any desired degree of tension
or frictional contact.
If desired, a separate wheel or surface may be provided for the brake J, instead of
having it press upon the same surface of the wheel C that engages with the driving
wheel C¹.
I do not broadly claim the feature of a tiltable or invertable reel irrespective of
construction, but-
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
