This is an invention for a machine for sealing
poules in position for sealing, the facility with
ampoules> or equivalent containers of fusible ma
terial such as glass after `the same have been
filled.
Due to the fact that ampoules of the same ca
which they may be emplaced in and removed
from the machine, the means for compensating
for the variation in the> size of the ampoules
which maybe sealed by the machine and the
pacity vary considerably in the outside diameter
manner in which the parts of the machine sub
ofthe necks thereof, it is essential in sealing the
same by the direct action of a flame jet impinged
thereagainst that the length of time to which the
neck is subjected to the heat of the flame jet
be regulated to within precise and very narrow
limits to avoid damage to the ampoule and waste
of the contents. When the fusing and sealing
are 'carried out by and depend upon the judg
ment of an operator, only those of experience and 15
possessing a high degree of skillfcan perform this
type of work satisfactorily.
‘
The present invention comprehends a machine
of the character set forth and for the purpose
specified which functions to automatically fuse
jected to the heat of the flame jets are cooled
to protect the same against damage by overheat

the ampoules and the discontinuance of the same 40
thereto, together with means governed by the size
of the outside diameter of the neck of each in

fusing and sealing thereby avoiding considerableV
waste.
As a still further feature, the invention em

frame will thus have been shifted to the left, thus
disengaging the terminals B9 from the teeth 10,
freeing the rack bars 60 to descend and depress
the leaf springs 52 thereby permitting the air to
flow through pipes 41 to discontinue the flame jets
against necks. It will be evident from the con
struction and mode of operation set forth `that
the length of time which the 'flame jets are ap
plied to the individual ampoules in accordance
with the size of their outside diameters, is con
trolled by starting the application of the flame
jets to the ampoules at varying times and discon
tinuing the application of said flame jets simul
taneously. That is, the larger the outside diam
eter of the ampoule neck, the earlier the ñame
jets are applied thereto and the smaller the out
side diameter, the later the flame jets will be
applied.
