My invention relates to improvements in bun
dles and the preferred method of producing them,
with particular reference to use in connection
with the preparation of ingots for handling ‘and
shipment.
'
‘
It has been the practice, for example, to “run”
or cast magnesium into pigs or ingots weighing
about ?ve pounds each, such ingots being in the
form of elongated bars substantially trapezoidal
in cross section, with the taper ‘toward What is
herein referred to as the top faces of the bars.
and without any substantial danger that an in
got will slip out longitudinally even if looseness
should develop in a bundle when handled or dur
ing transportation. For accomplishing this ob
ject, a plurality of ingots are arranged in partial bundles or‘sub-units, held together by a
?exible metal binder formed into a loop about
some of the ingots of the sub-unit and engaging
the notches of the ingots and tightened in a novel

Metal ingots are usually very difficult to hold
in groups or bundles. In the ?rst place, the in
gots, because of their rigidity and non-compres
sibility, cannot well be sprung or compressed as 30
an aid to effecting and maintaining tightness of
a bundle. In the second place, ingots are not
uniform in size and shape and their surfaces are

provide an improved method of assembling and

bundles may be ‘produced capable of being han

of the standards I4 and table I5 at an angle
from the horizontal is'such that the bars I‘I, I9

of the process, (see Fig. 4) two additional bars
2| and 22 are placed in position in base to base

stood that the invention is not to be limited to
such arrangement and method except so far as
the claims ‘may be so limited, since it is possible
that changes might be made in the arrangement
or the ‘method without departing from the spirit
of the claims.

the end portions of the band or binder, which
connector is adapted preferably to allow an in

A sixth bar 24 is‘ then placed in position on the
outer face of the binder I8 and is driven or
otherwise forced downwardly toward the oppo

take up any slack in the loop binder I8. The bar
