Abstract: 1,123,277. Hydraulic apparatus for loading machine-rollers. JOH. KLEINEWEFERS SOHNE. Nov.29, 1966 [Jan. 3, 1966], No. 53399/66. Heading F1P. A hydraulic system for a calender press includes a pair of cylinders 9, 10 containing pistons 16 attached to the uppermost set of rolls (not shown), and electrically operated valves 6, 7 that can be set in any one of three different ways so as to regulate either the loading or the position of said rolls relative to a lowermost set, a pair of hydraulic accumulators 19 on the output side of two pumps 1, 2 being disconnected therefrom whenever the valves aforesaid are set to effect lifting of the uppermost set of rolls so that the entire output of the pumps is directed to the cylinders 9, 10 during such action, which may be required in an emergency, e.g. when the web of material such as paper that is being calendered is damaged. Push-button switches 26, 27, 28 control the valves 6, 7, the switch 26 being operated when the uppermost set of rolls is to be raised, operation of which switch may be initiated by a photo-electric device (not shown) detecting damage in the beforementioned web. In one setting of the valves 6, 7 (as shown), the two ends of each of the cylinders 9,10 are connected to a reservoir 3 for hydraulic fluid whereby loading of the rolls is solely due to their own weight and that of the pistons 16. In another setting, both ends of each cylinder are connected to the output sides of the pumps so as to reduce the loading of the uppermost set of rolls. Alternatively, additional loading is effected by the output sides of the pumps being connected to the uppermost ends of the cylinders. In a third setting, the output sides of the pumps are connected to the lowermost ends of the cylinders while the other ends thereof are connected to the reservoir so that the uppermost set of rolls is lifted. The accumulators are charged with hydraulic fluid through conduits 22 whenever the uppermost ends of the cylinders 9, 10 are connected to the output sides of the pumps, charging through conduits 20 being prevented by non-return valves 21. Alternatively, the accumulators are charged through electrically controlled valves 24 and conduits 25, which valves are closed when the third setting aforesaid is selected.

A latch for a door comprises a pivotally mounted latch member 3 and a blade spring 10 which in cocked position is bowed to hold the latch member in an unlatching position and a trip member, a sliding bar 18 for engagement with the door frame or a member fixed thereto on door closure, the resultant displacement of the trip member acting to move the spring overcentre to a tripped bowed position with accompanying movement of the latch member to a latching position in which it is then retained by the spring. When an actuating lever 27, which is pivoted below the latch member on a back plate 1, is rotated, a pin 29 thereon engages the latch member 3 and rotates it to unlatching position simultaneously moving the spring 10 overcentre to retain the latch member in unlatching position. The actuating lever 27 is also rotated to release a second latch member 4 provided with a blade spring 12 and which holds the door in the open position. The sliding bar 18 has two projections 20, 22 for tripping the springs, to rotate the latch members to latching positions. Alternatively a stop may project from the door frame. Instead of a sliding bar the latch members may be operated by a blade lever pivoted to the outer side of each blade spring. One end of each blade spring 10, 12 passes through a diametral slot in a boss 16 of a latch member and is anchored below the pivot of the latch member, the other end is anchored to the back plate 1. A rotary inside locking member 32 above the actuating lever 27 is actuated to block the actuating lever and the latch member.
