F16P 1/005 ・{Guards for rolls in calandering or other roll machines, e.g. nip guards, finger guards}

F16P 1/02 ・Fixed screens or hoods

F16P 1/04 ・Screens or hoods rotating with rotary shafts

F16P 1/06 ・specially designed for welding

F16P 3/00 Safety devices acting in conjunction with the control or operation of a machine; Control arrangements requiring the simultaneous use of two or more parts of the body (F16P 5/00 takes precedence)

F16P 3/001 ・{Safety devices for guarding the human operator of punch presses or like machine tools performing an opening and closing travel}

F16P 3/003 ・・{by application of a specific control arrangement, e.g. specific switching systems or two-hand control}

F16P 3/005 ・・{having a movable screen or a sensor influencing the switching system}

F16P 3/006 ・・{having a screen moving with the machine and moving the operator out of danger, or restraining the operator, without influencing the switching system}

F16P 3/008 ・{Devices for directly stopping or interrupting the drive or gear in case of danger to the machine, e.g. devices with clutches}

F16P 3/02 ・Screens or other safety members moving in synchronism with members which move to and fro

F16P 3/04 ・・for machines with parts which approach one another during operation, e.g. for stamping presses

F16P 3/06 ・・・in which body parts of the operator are removed from the danger zone on approach of the machine parts

F16P 3/08 ・in connection with the locking of doors, covers, guards, or like members giving access to moving machine parts

F16P 3/10 ・・in which the operation of locking the door or other member causes the machine to start

F16P 3/12 ・with means, e.g. feelers, which in case of the presence of a body part of a person in or near the danger zone influence the control or operation of the machine (F16P 3/08 takes precedence)

F16P 3/125 ・・{Guards for rolls in calandering or other roll machines, e.g. nip guards, finger guards}

F16P 5/005 ・{Overload protection by energy absorbing components, e.g. breaker blocks, shear sections}

F16P 7/00 Emergency devices preventing damage to a machine or apparatus (F16P 1/00, F16P 3/00, F16P 5/00 take precedence; indicating means, see the appropriate classes)

F16P 7/02 ・by causing the machine to stop on the occurence of dangerous conditions therein (devices in bearings affected by abnormal conditions F16C)
