My invention relates to improvements in cap
ping machines and one of the objects thereof is
to provide a capping machine for applying caps
a suitable stationary cam track, not shown, for
the purpose of moving the crowner up and down
to receptacles having comparatively short necks,
during the crowning operation. This yoke car
ries at its lower end a hollow cylindrical housing
such for instance, as short-necked bottles and
cans.

machines is adapted to apply the crown or cap

that the neck of the bottle may pass well through
lines is'to use a receptacle in the form of a
housing and carrying at its lower end a crimping

provided with an annular ?ange 6 adapted to

mechanism. This crimping mechanism prefer
ably comprises a plurality of segmental crimpers

This sleeve is provided with a plurality of dogs
l5 operating in slots 16 in the wall of the sleeve
and pivoted as at l‘! in the slots. The noses it
of the dogs, in normal position, engage in notches 30

these dogs are maintained in their locking posi
tion by a stem 21} forming a part of a plunger 2!
in turn operating in the hollow plunger or sleeve
6. This stem or head 29, in normal position of
the parts, is positioned between the dogs at their
upper ends, as illustrated, and prevents the dogs
from moving out of engagement with the notches.
The head or stem 20 is connected by a restricted
portion or neck 22 with the plunger 2! and the
lower end of the head 20 at the point where it
joins the neck is provided with cam surfaces 23.
A similar cam surface 24 is provided at the upper
end of the plunger 2!, at the point where the
neck 22 joins the plunger.

In operation, the receptacles are fed beneath
the crowner, in any suitable manner, and after
being placed beneath the crowner the crowner is
adapted to descend for crimping the crown in

around the bead of the receptacle. In order to
receive and maintain the crown in a position to
be placed upon the top of the receptacle as the
crowner descends and in order to guide the neck

crown, I provide a crown rest 28. This crown
