Abstract
1315841 Machinery safety devices MASTERGUARD CO Ltd 21 July 1971 [22 April 1970] 19358/70 Heading F2J In a safety device for a pneumatically, or hydraulically, operated laundry press wherein the clothes pressing area is completely surrounded by a plastics-coated mesh guard 4 vertically slidably carried by cross-bars 3 on studs 2 of a fixed frame 1 and lightly downwardly urged into its closed position by weak springs on the studs 2, the guard cross-bars 3 have projections 6 engaging a pair of linked bleed valves 5 which control a main valve 7 connected between the fluid pressure supply 8 and the power operating cylinder of the press ram 9 whereby opening movement of the guard during operation of the press operates the bleed valves 5 to exhaust a control chamber 12 of the main valve 7 which is then downwardly spring urged to close the fluid pressure supply 8 and exhaust at 10 the press ram cylinder 9 whereby the press ram is spring returned to its upper inoperative position. When the guard is again closed the main valve 7 may again be opened by a button operated valve 13 which allows high pressure fluid to re-charge the chamber 12 of the main valve 7 to overcome the return, i.e. closing spring of the main valve 7 which is thus raised to again connect the fluid pressure supply 8 to the press ram 9 for operation thereof.
