shifting or depressing needles 12 there are stationarily arranged the arresting blades 17 fixing the upper shed position of the lifting wires 8 and furthermore the likewise stationary arresting blades 18 fixing the lower shed position to provide the necessary coaction between the lifting wires 8 and the arresting blades 17 18 these lifting wires 8 are provided with the arresting hooks or tongues 16 or equivalent structure considerably below the arresting blade 18 there is located a lifting wire board or floor 19 the mode of operation of the above discussed jacquard machine is as follows initially there is assumed a starting position where the lifting blade 1 is in its lower reversing position the lifting blade 2 is in its upper reversing position and the lifting wire 8 with its arresting hook 16 is suspended in the stationary arresting blade 17 upper shed position of the lifting wire the shifting or depressing needle 12 is located in its left ineffectual position where the lifting wire 8 is not depressed or shifted towards the right now the lifting blade 1 is moved upwards and at the same time the lifting blade 2 downwards the hook 7 engages in the hook 14 and entrainably shifts the lifting wire 8 upwards thereafter the shifting or depressing needle 12 is moved towards the right as indicated by the arrow 13 so that the.
