whereupon link 50 is pivoted downwardly thus moving clamping members 32 down into engagement with the ear extensions 38 this overcenter movement of the linkages transmits a force to the clamping member 28 which draws the latter upwardly toward the ear extensions 38 in turn applying a force to the bottle lip 20 which moves the bottle upwardly into tight sealing engagement with the head 15 continued downward movement on the link 50 to the position shown in fig5 causes the clamp assemblies 26 to lock into place and in turn locking the bottle 10 in the head 15 in order to remove or exchange a bottle 10 the links 50 are simply moved outwardly and upwardly thereby releasing the clamping members 32 from the ear extensions 30 whereupon the clamping members 32 may be moved outward to clear the ear extensions 38 at this point the bottle 10 may be moved longitudinally downward away from the head 15 then the clamp member 28 along with the clamping assemblies 26 may be slid away from the bottle 10 and installed on a fresh bottle which is then installed using the installation procedure described above from the forgoing it is apparent that the quick release clamping system described above not only provides for the reliable accomplishment of the objects of the invention but does so in a particularly effective and economical manner it is recognized of course that those skilled in the art may make.
