supported as described in connection with FIG. 11.
As containers are conveyed through the topping or
headspacer machine they are resiliently held in against
same oriented (i.e. vertical) position in that orbit. That
is, the brackets 227 are always hanging and maintained
in the downward position as shown in FIG. 10. Like

is shown supported along opposite sides by inner and
outer elongated angle members 259 and 251, respec

ported from the outer angle member 255), one being ad
always in their upright position by reason of the foregoing
intermovement of the parts.
Reference may now be had to FIGS. 10 and 11 for a
description of the headspacer plungers 9 and the manner
in which they are supported on the brackets 227. Each
of the hubs 228 is provided with a vertical opening for

provided with an opening or slot 229‘ (FIG. 10) in the

seen that the rounded end 234 which engages the upper .
end of the recess 233 is not directly in line with the
handle portion 236 but is slightly offset or eccentric with
respect thereto.
Furthermore, each recess 233 is so
formed in relationship with the contour of the end 234
that when the lever 235 is in the position shown in FIG.
11 the parts are wedged together. In other words, to

by loosening the clamping screw 53 on one side and the
