the intermediate member being connected to the coupling parts by ridges, pins, balls, or the like guided in grooves or between cogs

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slideably connected > the intermediate member being connected to the coupling parts by ridges, pins, balls, or the like guided in grooves or between cogs

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive (couplings disconnectable simply by axial movement F16D1/10; slip couplings F16D7/00) > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > Hooke's joints or other joints with an equivalent intermediate member to which each coupling part is pivotally or slidably connected (F16D3/18, F16D3/20 take precedence) > the intermediate member being connected to the coupling parts by ridges, pins, balls, or the like guided in grooves or between cogs
