Abstract

1,244,781. Magnetic switches. JOHN LAING & SON Ltd. 3 Sept., 1968, No. 5554/69. Divided out of 1,243,010. Addition to 1,156,331. Heading H1N. [Also in Divisions E1 and G3] A magnetic switch for use as a sensing device on a concrete laying machine has reed contact units 62, 63 controlled by permanent magnets 52, 53 on the ends of a bar 50 which is pivoted at 50 and provided with a balance weight 60 to counterbalance an extending arm 55 which is movable between stops 61. The movement of the arm depends upon the engagement of a spring biased sensing flap 56 on the end of the arm with a datum such as a taut wire.
