core, of jaws connected with said core, means for normally
separating said jaws, a stop on said core having a forward
extension adapted to enter the bottle-neck, levers pivoted

constitute part of the forming-device and working in said
extension, links pivoted in the slot and having elongated
slots in their rear ends, pins passing through the levers and
the slots in the links, whereby when the jaws are closed
the forming-means will be projected beyond the forward
extension both laterally and longitudinally, as set forth.
(7.) In a tool for forming bottle-necks, the combination
with a central core having an enlargement near its forward
end, jaws connected with said core, of a forming-device
mounted in the core and having connection with the jaws,
said forming-devices being adapted to rest normally in the
enlargement of the core but to be projected beyond said en-
largement both laterally and longitudinally when the jaws
are moved towards each other, as set forth. (8.) In a tool for
forming bottle-necks, the combination with a central core
having an enlargement near its forward end and a stop or
shoulder 6, of jaws connected with said core, a forming-device
mounted in said core formed in part by levers pivoted to the
core and having connection with the jaws and links pivoted
in the core and having connection with the lever ends, said
forming-devices being adapted to rest normally in the enlarge-
ment of the core, but to be projected beyond said enlargement
both laterally and longitudinally, as set forth. (9.) In a tool
for forming bottle-necks, the combination with a central core
having links 3 pivoted to its rear end, jaws pivotably con-
ected to said links and provided with forming-surfaces at
their forward ends, an enlargement near the forward end of
said core, a forming-device mounted in said core and formed
in part by levers pivoted to the core and having connection
with the jaws, and links pivoted in the core in advance of the
enlargement and having connection with the lever ends, said
forming-device being adapted to rest normally in the enlarge-
ment of the core, but to be projected beyond said enlarge-
ment both laterally and longitudinally when the jaws are
moved towards each other, as set forth.
