It is composed of five distinct parts as follows: (a) Two small arms are fixed at the top of the machine, oneat each side. Two pointed set screws w4th lock nuts are set in thearms and the batten or swing is supported on these points. (b) The batten, which is in the form of a square iron fra,me.(6) Two cups set in the batten frame, which support the cylinder. The cups are made of iron or brass and are held inplace by a bolt with thumb screw on the outside of the frame ofthe batten. Set into the bottom of the batten frame and pressing. K Fig. 16. Details of Batten or Swing Cylinder Motion. upwards against the cups, are two set screws whose purpose is toraise or lower the cylinder. (d) The cylinder. This is a square prism with a numberof holes bored on each side to correspond with the needles in themachine. On each of the four sides of the cylinder and near eachend there is a small brass peg (shown in Fig. 17) for the purposeof holding the card in the correct position on the cylinder. (Theperforations in the cards should be over the holes in the cylinder).The pegs are set so they can be adjusted to the right or left. Atthe ends of the cylinder square iron castings with rounded edgesare fixed. 294 JACQUARD MACHINES 17 ((?) A spring hammer, the flat end of Avhich rests on thecasting on the end of the cylinder.
