be desired to employ the baling press according
to the present invention, for baling some other
material, it‘ will be apparent to those skilled in
the art that conventional changes may be made
in the structure to permit the tying of the bale

ment of the camming surfaces 81, and thus of
the I beam 82 and the piston rod 59 is limited by
a collar I03 disposed loosely about the spring
I00. The length of the collar I03 is designed so
that when it simultaneously abuts against the col

Fig. 8, the arms 92 will be in vertical or dead

the pins 98 move down the camming surfaces 81,
they will move into the hooks 88 so that when in

material to be baled is loaded therein. It will be
understood that the ejector structure is not dis
closed in relation to any of Figs. 1 through 9 for
the purpose of simplifying those disclosures. As
shown in Figs. 10 and 11, the ejecting member
II 0 has a width equal to that of the ?nished bale
I3I and a depth as measured by the length of
the foot I I I, which is slightly less than the depth
of the ?nished bale I3I. When the compressing
chamber 2 is ?lled with material to be baled, the
bale is formed in the manner hereinabove de
scribed. The position of the ejecting member I I0
is such that the bale I3 I' is formed thereon. The
recess H2, in which the foot portion III of the
ejecting member H0 is disposed, is provided to
prevent scrap metal being baled from forcing its

withdraw the arms 92 from dead center position
upon initial rearward movement of the piston
rod 50 carrying with it the camming surfaces 81.
When the bale I3I has been formed on the
ejecting member H0, and the platens ‘I and H,
20 shown in Fig. l, withdrawn, the cover 8 is re
moved from over the compressing chamber 2 by
moving the carrier 22 to the right, as viewed in

in a closing direction, the force exerted by the
piston rod I 42 being transmitted to the spring
I43 to the carriage I40, and from the carriage I40
through the bar members 62 to the guiding'mem
bers 63. Return movement of the cover 6 is ac
complished by reversing the direction of move
used. Also, while the foregoing speci?cation has
described a press for :baling as such, it will ‘be
understood that the invention ‘may be'employed
for other forms of compressing and ‘molding'op
erations, and accordingly, we do not wish to be
limited except by the scope of the following
claims.
We claim:

As the rod I42 moves forwardly the rollers

their pivots I50, rollers I56 on the upper ends
thereof move rearwardly along horizontal stops
