Method to use desired parts of specific established cycle times in programmer devices of the type normally called "timers", whereby there are included a cams assembly and a timing assembly that determines the times and conditions the movement of the cams assembly, the timing assembly including a thermostop assembly suitable to halt momentarily the movement of the timing assembly when a thermostop contact (43) is connected, in which method a specific additional external switch (145) is actuated to use desired parts of a specific established cycle time and remains active in relation to the thermostop assembly (40) for a minimum defined time when a first normally open contact (46) relating to that specific established cycle time is actuated by a specific cam (47). Programmer device of the type called a "timer", which comprises a cams assembly and a timing assembly that determines and conditions the movement of the cams assembly, the timing assembly including a thermostop assembly suitable to halt momentarily the movement of the timing assembly, in which device in parallel with the line feeding the thermostop (40) and comprising at least a thermostop contact (43) there are included in series an additional external switch (145) with normally closed contacts and a first normally open contact (46) associated with a specific cam (47) of the specific established cycle time of which desired parts are to be used.

Device for the discontinuous advance of the cam unit (13) achieving the method as above, the eccentric (14) being associated with means (19, 21) to accelerate/decelerate the transport lever (11) which intervene for at least one segment of each individual advance (16) of the cam unit (13) so as to define at least three semi-steps in advance at differentiated speeds, a first semi-step in advance (16a), a third, intermediate semi-step (16b) and a second semi-step in advance (16c), wherein the third, intermediate semi-step (16b) has a reduced speed compared with the first (16a) and second (16c) semi-steps in advance.

摘要:
Method and device to free contacts in timers employing rotary disks that bear the required programme substantially on their circumferential periphery, a movable contact (20) having one end operating continuously on a common contact (24) and having its other end cooperating with a first transit contact (25) or with a second transit contact (26), the movable contact (20) being actuated by the periphery of the rotary timer disks (23) which acts on a feeler element (35) of a lever (21) able to rotate about a rotation pivot (22), a spring (27) being located between the movable contact (20) and the lever (21) and imparting to the movable contact (20) a lateral traversing movement (29) and a lengthwise traversing movement (30), in which method when the spring (27) cannot actuate the movable contact (20) owing to adherence of the latter (20) to the first transit contact (25), a second abutment (41) included on the movable contact (20) acts on the lever (21), which comprises a second inclined surface (39) having an angle of inclination "β", the second inclined surface (39) inducing in the movable contact (20) a lengthwise traversing movement (30), which also displaces the movable contact (20) sideways and thus breaks the adherence of the same (20) and restores the resilient action of the spring (27).
