Abstract
Abstract A rotary shaft and a rotary closure-engaging device which entrainingly engages a closure to be threaded onto a container, are connected by a coupling arrangement having one coupling member connected with the shaft and another coupling member connected with the closure-engaging device. One of these members is provided with a plurality of torque-transmitting elements which engage a circumferential surface of the other member in torque-transmitting relationship but are so yieldably mounted that when a predetermined torque limit is exceeded, a small fraction of the torque-transmitting elements becomes disengaged from the circumferential surface.

Total Claims: 15
Claim 1
Independent Claim
194 words
In an apparatus for threading closures onto bottles and similar containers, a combination comprising a rotary shaft; rotary closure-engaging means for entrainingly engaging a closure to be threaded onto a container; and coupling means for coupling said engaging means with said shaft, comprising a first coupling member connected for joint rotation with said shaft, a second coupling member connected for joint rotation with said engaging means, a plurality of torque transmitting elements arranged on one of said members around the axis of rotation of said rotary shaft, and a ring surface on the other of said members, said torque transmitting elements yieldably engaging said ring surface and said ring surface surrounding said axis of rotation, said torque transmitting elements being movable in directions the inclination of which relative to said axis of rotation is common for all torque transmitting elements and said ring surface gradually rising slightly from a first level to a second level and descending steeply at only one part of its circumference from said second level to said first level, the direction of rising and descending of said ring surface being the direction in which said torque transmitting elements are movable.
Claim 2
Dependent Claim
194 words
In an apparatus for threading closures onto bottles and similar containers, a combination comprising a rotary shaft; rotary closure-engaging means for entrainingly engaging a closure to be threaded onto a container; and coupling means for coupling said engaging means with said shaft, comprising a first coupling member connected for joint rotation with said shaft, a second coupling member connected for joint rotation with said engaging means, a plurality of torque transmitting elements arranged on one of said members around the axis of rotation of said rotary shaft, and a ring surface on the other of said members, said torque transmitting elements yieldably engaging said ring surface and said ring surface surrounding said axis of rotation, said torque transmitting elements being movable in directions the inclination of which relative to said axis of rotation is common for all torque transmitting elements and said ring surface gradually rising slightly from a first level to a second level and descending steeply at only one part of its circumference from said second level to said first level, the direction of rising and descending of said ring surface being the direction in which said torque transmitting elements are movable.
