Abstract

1533793 Machinery safety devices HIGHWOOD ENG CO Ltd 1 June 1977 [11 June 1976] 24252/76 Heading F2J A safety device, for use in a spot welding machine, comprises a pair of members 12, 13 guided for vertical movement by rollers 11, the member 13 being raised and lowered by a pneumatic piston and cylinder unit 14 and the member 12 carrying a guard 17 and following the movement of member 13 under its own weight. The downward movement of member 13 causes a lever 21 to be pivoted to operate a switch or valve 22 to start the operation of the machine. The presence of a finger too near the electrode 18 obstructs the movement of guard 17 and causes an abutment 19 of member 12, which abutment would otherwise fit a notch 24, to prevent the lever 21 from pivoting to operate switch or valve 22. The arrangement may also be used in a riveting machine.
