摘要： The bobbin racking mechanism for a Jacquard machine comprises two stationary shafts arranged side-by-side on a fixed support. One shaft supports for free rotation a drive unit including a drive spur gear which supports on one face an input bevel gear pinion and on the other face an eccentric cam; a transmission unit including a tubular housing having a cross-like section to define four stop arms; two bevel gear pinions are arranged in the tubular housing for rotation about an axis transverse to the stationary shaft, the pinions being in mesh with the input gear pinion; an output unit having an output bevel gear pinion in mesh with the transmission gear pinions, a disc cam having two diametrically opposed recesses and an upper plate with arcuate recesses for racking the bobbins. The other stationary shaft supports an operator member including a sleeve with a pallet fork, a locking device assembled of two superposed coupling plates, the lower plate being linked by a connecting rod to the eccentric cam in the drive unit and continuously performs an oscillating movement and the upper plate is connected to the sleeve. The pallet fork has two radially directed arms forming an angle with one another. One arm is engageable with the recesses in the cam disc in the output unit whereas the lower arm is engageable with the stop recesses in the cross-like housing. A coupling device includes a pivotable ratchet arranged in one of the plates and actuated by means of electrical or mechanical driving mechanism to engage the lower plate with the upper plate when actuated.

摘要： The bobbins in a jacquard-type lace-making machine are displaceable by means of mechanisms each constituted as an output member carrying one or two bobbins, a transmission member and a continuously rotating drive member. The drive and output members are formed with respective bevel gears centered on the axis of the device and the transmission member carries at least one bevel gear rotatable about an axis transverse to the rotation axis for the mechanism and meshing with both of the gears so that the output gear can rotate in a direction opposite that of the drive gear. An operating shaft carries a pair of operating arms and is displaceable between a stopping position in which the one arm arrests the output member while the other arm allows the transmission member to rotate and a racking position in which the one arm allows the output member to rotate whereas the other arm arrests the transmission member. A cam may be provided on the drive member or on the output member for forceably returning the operator to the stopping position after 180.degree. displacement of the output member.
