Abstract: 1282396 Welding by pressure EVG ENTWICKLUNGS U VERWERTUNGS GmbH 19 April 1971 [25 March 1970] 24702/71 Heading B3R In an electric resistance welding machine in which a pair of electrodes are disposed on one side of a workpiece opposite a current bridge which is adapted to conduct welding current between the two points contacted by the electrodes, the current bridge is mounted so as to bear with equal pressure on the two welding points in spite of differences in thickness of the workpieces at the two points. In a wire mesh welding machine in which transverse wires Q are to be welded to longitudinal wires L 1 , L 2  of different diameters the current bridge is pivotally attached to thrust rods 6, 7 resiliently and deflectably mounted on a beam 20. Springs 8, 9 which may be separately adjusted by threaded bushes 10, 11 act respectively on collars 14, 15 on the two thrust rods and in the inoperative position of the current bridge urged the collars into self centring engagement with conical seating members 16,17 fixed to the lower edge of the beam 20. When the beam 20 is lowered for the welding operation the contact surfaces 3a, 3b of the current bridge make contact with the wire Q and on continued lowering movement of the beam 20 the collar 14 is lifted from engagement with its seating the spring 8 being progressively compressed while the contact surface 3b forces the wire Q, into contact with the wire L 2 . The collar 15 then begins to lift from its seating 17 and compresses the spring 9. The initial adjustment of the springs 8, 9 is such that at the final welding position of the beam 20 and current bridge 3 the contact pressure at the welding intersection is the same.

Title: A machine for marking extruded bricks
IPC: B28B11/08
Filed: 1959-07-28
Abstract: 879,491. Marking extruded bricks. WILKINSON, R. July 28, 1960 [July 28, 1959], No. 25810/59. Class 87(2). A machine for marking a column of extruded clay, to be subsequently cut into individual bricks, comprises a roller 5 bearing on its periphery a number of embossed marks equally spaced circumferentially and being rotatable by the passage over it of a column 7 of clay from the extruder, and means to bring the roller 5 to rest with the mark that is then short of the uppermost part of the periphery of the roller always in a predetermined angular position with respect to the vertical plane through the axis of the roller, such means being capable of being overcome by the driving contact between the column 7 and the roller 5. In general, the weight of the column 7 ensures enough pressure for the marks on the roller to impress the clay but this pressure may be supplemented by a felt-covered roller 21 positioned to bear on the upper side of the column and urged downwardly by a spring. One end of the roller shaft 3, Fig. 5, passes through a circular housing 8 and these carries a flange 9 with shallow Vee cam notches 10 equally spaced round one face and directed towards a plunger 13 carrying a castor roller 14 which is urged towards the notches 10 by an adjustable spring 15. The offsetting A of the castor roller 14, Fig. 6, assists the notches 10 to ride easily past it in the direction B when the roller 5 is driven by the column of clay. One of a number of interchangeable rollers 5 may be used, each having as many marks-numbers, letters, name, &c.-as there are cam notches 10, so that whatever the diameter of the roller in use, the castor roller 14 comes to rest in a notch associated with one of the marks when the roller 5 ceases to be driven, and the spring 15 urges the roller 14 to the bottom of that notch to accurately position the roller 5 which it has assisted to come to rest. Flange 9 is angularly adjustable by means of the screw 17 so that the angular position at which the marks are brought to rest may be predetermined. In an alternative embodiment, Fig. 9, a plunger 59 is controlled by a solenoid 55 which is operated when the clay column passes over and depresses two light, small diameter transverse rollers, covered with felt, one on each side of the marking roller 43. The plunger 59 serves to rock a lever 60 to operate a vertical plunger 62 carrying a follower roller 64 which, when the solenoid 55 is not operated, is forced into a notch of the star wheel 65 lying immediately below it on the shaft 67 of the roller 43. Operation of the solenoid 55 brings the follower roller 64 clear of the star wheel 65, thus enabling the roller 43 to be rotated.
