A drive system for a weaving loom includes at least one four-pivot three-link drive or preferably two such drives for transmitting drive power from a main loom shaft through a cam drive to a slay shaft coupled to the cam drive through the four-pivot three-link drive. The use of two four-pivot three link drives permits operating the weaving loom selectively for producing terry cloth and/or smooth fabric. Each of the four-pivot three-link drives (DL, DR) has four pivots or journals (A, B, C, D) and three links (24, 38, 43; 25, 40, 44). Each four-pivot three-link drive cooperates with a roller carrying cam follower (15) that is controlled by an eccentric cam assembly (7). Both four-pivot three-link drives effectively operate the slay shaft (46) of the loom. A control and engagement mechanism (33, 54) provides for the switching from one four-pivot three-link drive to the other and vice versa, whereby a switch-over from the production of one type of fabric to the other is facilitated.
A drive system for selectively controlling an angular motion and an angular range of said motion, comprising an angularly movable component (45) to be driven, a power input unit (1) including a driving shaft (3), an eccentric drive cam assembly (7) connected to said driving shaft (3) for rotation with said driving shaft (3), a cam follower (15), at least one cam follower element (11, 12) carried by said cam follower (15) and engaging said eccentric drive cam assembly (7), at least one four-pivot three-link first drive (DL or DR) driven by said cam follower (15), and means connecting said four-pivot three-link first drive to said cam follower (15) and to said angularly movable component (45) for transmitting an angular drive power from said driving shaft (3) to said angularly movable component (45).
A loom comprising a slay shaft, a main loom drive shaft, a drive system connected between said main loom drive shaft and said slay shaft for selectively controlling an angular motion of said slay shaft and an angular range of said slay shaft motion, said drive system comprising a power input unit (1) including said main loom drive shaft (3), an eccentric drive cam assembly (7) connected to said main loom drive shaft (3) for rotation with said main loom drive shaft (3), a cam follower (15), at least one cam follower element (11, 12) carried by said cam follower (15) and engaging said eccentric drive cam assembly (7), at least one four-pivot three-link first drive (DL or DR) driven by said cam follower (15), and means connecting said four-pivot three-link first drive to said cam follower (15) and to said angularly movable slay shaft (45) for transmitting an angular drive power from said main loom drive shaft (3) to said angularly movable component (45).
