Apparatus for applying container caps of different sizes to containers includes a main housing arranged for rotation by a driving spindle, an upwardly biased cam rod coaxially disposed relative to the spindle and movable reciprocably, a releasable holding device normally restraining the cam rod against upward movement, a transverse cam follower shaft mounted in a transverse passage formed in the cam rod and having outwardly projecting ends, on which a pair of cam followers are rotatable, a main ...

A capping system for a roof ridge comprised capping members, e.g., ridge tiles, connected to a reentrant portion arranged to overly ends of tiles adjacent the ridge. Filler members are disposed between the tiles and reentrant portion. Ridge interior is ventilated by circulation of air passing over the filler member and through the reentrant portion.

A capping head including a housing assembly including a magnetic clutch interconnecting a drive spindle and a quill for applying a closure to a container. The magnetic clutch consists of opposed rings of magnets and one of the rings is disposed in a piston ring assembly that is quickly and easily adjustable relative to the other to vary the torque limit of the clutch. A simple yet efficient clamping assembly is employed to facilitate ready adjustment and retention of the movable piston ring.

A device for screw-tightening caps on containers such as bottles has a cap chuck head for grasping and holding each cap with holding pawls, a driving shaft, and a friction clutch mechanism constructed separately from the chuck head but mechanically coupling the driving shaft and the chuck head to transmit rotational power to the chuck head at torques below a predetermined maximum torque, at which the cap is screw tightened, friction plates of the clutch mechanism slipping at any higher torque to...

A machine for de-capping containers having screw caps is responsive to the presence or absence of a cap on a container and includes an annular body mounted for rotation about a vertical axis and for upward and downward movement towards and away from a container. The body carries on its periphery vertical arms which are pivotable about tangentially extending axes, the lower ends of the arms carrying tools operable to grip the cap. Coaxially within the body is a plunger-like probe which is spring ...

A method and apparatus for converting conventional bottle crowning machines for the proper application of lighweight metal tear off closures. The standard crowner mechanism is detached from the free end of a work imparting shaft mounted for vertical reciprocation along its longitudinal axis. A tear off closure applying head is installed in place of the crowner mechanism with a self-contained compensating spring unit interposed axially between the shaft end and the applying head. The converted ma...

A fluorescent tube comprising a cylindrical glass tube having end portions, connection wires through the end portions, and a socket capping. The end portions are gas-tightly sealed and each has an annular collar and groove. The capping is made of an elastic, bendable thermoplastic material such as poly(ethylene-terephtalate). The capping comprises a frontal portion, contact pins therethrough electrically connected to the connecting wires, at least one drop of glue which dries at room temperature...

A disposable self-capping needle which can be completely contained with its own sheath before and after injection takes place. The enclosing needle sheath has a protective rear seal and an openable front lid. By removing the seal a syringe can be connected to an internal needle plunger assembly to permit reciprocating needle motion within its sheath. Injection is accomplished by opening the sheath's front lid after which the needle may be completely withdrawn back into the sheath for safe dispos...

A capping machine comprises a rotating carriage positioned above a conveyor delivering open neck containers to a work station position, the carriage including circumferentially positioned sockets that receive snap-lock caps in a fixed orientation from a second conveyor. The carriage rotates about an axis transverse to the direction of conveyance of the first conveyor so that the proximate carriage position closest to the first conveyor has a velocity in the same direction as the direction of con...

A hand-held device for installing caps on vials having a housing with an outer housing member and an inner housing member. The housing is sized to enable the device to be held in a hand of a user and placed over a vial to be capped. A shuttle member is rotationally disposed within the inner housing for transporting one of a plurality of caps stored in the housing from a cap storage station to a cap installation station within the housing when said device is operated. At approximately the same ti...
