Abstract: 1,257,200. Travelling matrix displays. CONTRAVES A.G. 18 Aug., 1969 [19 Aug., 1968], No. 41054/69. Heading G5C. In the type of sign wherein a travelling matrix of pivoted elements 30 has selected elements tripped columnwise by a column of pins (only one 53 shown) actuated by electromagnetic means 52, so as to expose one of their two contrasting faces 31, 32 thus to display the desired total resultant image; each element 30 comprises (Fig. 2) a pair of plastics material pressings 31, 32 plugged together as to embrace collars 25 on a vertical shaft (20) forming part of a travelling endless articulated chain mechanism (Figs. 1 and 9, not shown) each element carrying a reversing lug 36 for engagement with the setting pins 53 (Fig. 8) and with parts of an imagecancelling device (Fig. 5).  Cancelling device (Fig. 5).-In passing from a convex guide surface 41 to a concave one 42 (these surfaces preventing rotation) the reversing lug 36 of each element 30 is engaged in a gap 45 between plates 43, 44 at the vertical level of each row of reversing lugs. Thus faces 31, 32 inevitably become the trailing and leading faces respectively consequently it is always face 32 which is engaged by abutment 420 and constrained to rotate so that it finally is exposed radially outwardly. Setting device (Fig. 8).-On emerging from surface 42 of the cancelling device, the reversing lugs 36 of selected ones of a column of elements are engaged by pins 53; the elements are thus rotated. If rotated insufficiently owing- to imperfection or error, the element is restored to its original position by engagement of its leading edge with a string 54: this prevents ambiguity. If rotated sufficiently, its leading edge will distend string 54 enough for rotation to continue, the element being finally rotated into place by engagement with an abutment 56, its edge being bevelled at a central region 37 in order to roll on string 54.

The end of the mandrel assembly comprises a housing cylinder 10 having a generally cylindrical bore 11 in which is provided a piston 16 attached to an operating rod 14 coupled to the mandrel. A bore 18 in piston 16 accomodates a connecting in 20 which rotatably connects the rocker arm 25. The arm is bifurcated at its upper end 26 to form a pair of arms 28 on either side of the cylinder 10. The lower portion 30 of the arm terminates in a spheroidal portion 31 which is accommodated by a groove 37 in a rotatable cam roller 35. A fixed bracket 45 has upper and lower support elements 46, 47 which support a rotatable, threaded shaft 55 which, in turn, is connected to a fulcrum carriage 50 via an inclined threaded bore 54. Rotation of shaft 55 causes movement of the carriage along the shaft. This, in turn, causes the movement of a fulcrum pin 65 connecting arms 63 of the carriage within a slot 33 in the rocker arm by way of a slider element 66. In operation, shaft 55 is rotated to move the fulcrum carriage 50 along the shaft to select the appropriate position for the fulcrum pin with respect to the longitudinal slot 15 of cylinder 10. Upon rotation of the cam roller, the ball 31 of arm 25 follows the groove 37 about the cylindrical surface 36 of the roller towards the forward extremity 37<SP>1</SP> of the groove. This causes the arm 25 to pivot about pin 65 and move the bifurcating portion 26 rearwardly from the datum position and so operating the expanding of the segments of the mandrel. The slot 33 permits the arm to move downwardly in response to the constraint imposed by the linear reciprocating motion of the connecting pin 20 and piston 16. The throw of the operating rod may be varied by altering the position of the fulcrum pin 65 with respect to the slot in the arm 25 by adjustment of shaft 55 when the arm is in its datum position.
