‘This invention'hasto do with an apparatus
. 1 for wrapping a bundle of lengths-of wire together,
for shipping.
-
,
,
In the past, it has been common to arrange
r, a plurality of lengths of- wire together, in the
form of a bundle and to apply entirely by hand
anchor rings of wire at spaced points along the‘
length of thebundle, bringing‘ the ends of each
ring<together and twisting the same and then
10 bending the partsthus twisted ?at against the
bundle. In this manner the wires were kept
together and separation was prevented during
shipping and handling 01 the bundle as a whole.
This process of fastening the bundle is cumber:
15 some ‘and takes up a considerable‘ amount of
time. Moreover the resultant article is' very
rough, due to the protruding ends of the anchor
rings, often causing scratches and lacerations
of the hands, ripping of clothing, and catching
20 in and mutilating' wires of adjacent bundles.
It is accordingly one of the principal objects of
this invention to provide an apparatus with which
an attendant or operator may cooperate to wind
a wire or the like about a bundle of wire or the
3 like in spiral fashion lengthwise of the bundle
to thereby facilitate-the wrapping of the bundle.
Another object of the invention is to provide a
wrapping for a bundle of wire or the like, the
wrapping being of such construction as to provide
30 continuous engagement with the bundleof wire
substantially throughout the length of the bundle.
- A‘ further object consists in a method of ex
peditiously wrapping a bundle in secure fashion.
I Another object resides in the provision ,of a
35 bundle which presents substantially no sharp
projections, thereby. making for ease and safety
in handling, and eliminating injury to adjacent
bundles or other articles.
for pivotal movement on the frame, so that, once" . '
the wrapping of a bundle of wire has been Icom- 1'
pleted, the trough-dike structure may be shifted‘
as a whole about its axis parallel thereto to ‘there
by “dump.”_the wrapped bundle, whereupon the 5'
trough is returned to its original position to re- '
ceive another bundle to be wrapped. - Thetrough
is also adjustable vertically so that the bundle ’
may be substantially aligned with the rotating
spindle of the head stock, regardless of the diam- m
eter of the bundle. The chuck, is of such charg
acter that it is he
e and lends itself to di?er
ences in alinementbetween itself and the bundle
to be gripped thereby-v
-
-
v
The bundle is wrapped as ‘follows: The bundle 15
to be wrapped is preliminarily prepared for the ' _
wrapping operation and is then conducted to the‘
trough by the guide provided for this purpose.
It is then shifted longitudinally and one end, to
.
which I shall refer herein'as-the head, is tightly 2Q

portion of the wire from the spool adjacent the
rotating bundle, and moves lengthwise of the;
bundle as the latter rotates, permitting the wire ‘
to slip from his ?ngers and be wrapped spirally 3g
about ‘the bundle. When the attendantis ad
Jacent theppposite or tail end of the bundle, he 1
stops and permits the wire to be drawn from his
ilngers and wrapped into the form of contacting l '~
cells. This is continued for onefor vmore revoiu- 35
tions after the extremity has been reached, the
wire as ‘it leaves the attendant being urged by

~ advantage not only of time consumed inwrap
ping, but additionally of the catching of the por
tions .thus protruding with the wires of adjacent
bundles, thereby mutilating and often pulling
parts of. the wires thus projecting from their
respective bundles. - With the invention just out
lined, however, it is clear that there are no such
objectionable projecting portions, and the act or
operation of wrapping the bundle involves a
10 matter of a few moments.
Moreover the bundle
thus produced is much heater in appearance than
those heretofore made, and is more compact,
thereby providing a decided saving in shipping
expense. The lack of protruding parts more
over makes for much easier and safer handling,
whereas the handling of bundles of this charac
ter heretofore wrapped always involved the
danger of scratching or otherwise mutilating the‘
‘hands.

Further objects and advantages of the inven
tion will appear as the description proceeds.
On the drawings:
’
ures 1 and 2, the guide means II will serve to
move the belt to the left into engagement with
the ?xed pulley 1, to thereby rotate the spindle 6.
Fixed on the inner end of the spindle 6 is a
sleeve I2, and loosely surrounding the same is a
sleeve I 4 to which is pivoted at l3 an actuating
lever [5. The lever I5 is pivoted to the frame
base 3 at IS. A substantially H-shaped spacing
member I‘! is secured for rotation with the sleeve
l2 and receives at its opposite ends‘ pivoted levers 10
l8, each lever i8 having a tapered end i9 adapted
to be moved by a cam action byrthe frusto
conical surface 20 of the sleeve I‘. The levers
18 have at their inner ends chuck jaws 2| .
It
is thus apparent that upon movement of the 15'
lever l5 to the right as viewed in Figures 1 and
2, the ends IQ of ‘the leverslB will be cammed
outward and the ‘jaws 2| will be cammed inward
to thereby grip the head of the bundle to be
rotated thereby. A spring 22 constantly urges 20
the ends IQ of the levers i8 toward each other.

approximately in the plane indicated by the line axially with the-‘chuck. Additional supporting

on which the apparatus constituting the essence
vided in order that the operator may prelimi
narlly bind the ends of the bundle to prepare the
latter for the wrapping operation employingthe
apparatus. This means consists of a standard
v . 21 secured to the ?ange 3 and projecting toward 35
the attendant, that is, from. the front side of
the machine. Springs 43 constantly .urge the
brackets 24 toward the right as seen in Figure
3, and stops 46v on the mountings 26 limit move 40
ment in that direction. A lever 44 is suitably
mounted for rotation with one of the brackets
24 and may be employed to pivot the trough 23
against the action of the springs 43 when the
wrapped bundle is discarded to make way for a 45
bundle to be wrapped.
.
'
,The upper ‘end 28 of the standard 21 is in the
form substantially of the letter U and is adapted
to receive the head ofthe bundle to be wrapped.
Additional standards 28 are also secured to the 50
frame insubstantial alinement with the stand-»

portions of the standards 29, however, being some
