 F16P
SAFETY DEVICES IN GENERAL (safety devices adapted to machines or apparatus for special purposes, see the relevant classes for the machines or apparatus)
 F16P 1/00 - 
F16P 3/00
Devices protecting or preventing injuries to people
 F16P 1/00
Safety devices independent of the control and operation of any machine (protective devices for the eyes or ears, worn on the body or carried in the hand, A61F 9/00, A61F 11/00)
 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 3/02
·  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 3/14
·  ·  the means being photocells or other devices sensitive without mechanical contact
 F16P 3/16
·  ·  with feeling members moved by the machine
 F16P 3/18
·  Control arrangements requiring the use of both hands
 F16P 3/20
·  ·  for electric control systems
 F16P 3/22
·  ·  for hydraulic or pneumatic control systems
 F16P 3/24
·  ·  for mechanical controls
 F16P 5/00
Emergency means for rendering ineffective a coupling conveying reciprocating movement if the motion of the driven part is prematurely resisted
 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)
