in the latched position as best seen in fig1 therefore should the blade guard 18 rebound or should it attempt to move from its fully closed position and begin to rotate into the chamber 22 of the stationary part 12 of the saw 10 the projection 24 on the blade guard 18 comes into generally perpendicular contact with surface 37 of the blocking pawl 34 on the latching mechanism 26 further motion of the blade guard 18 is prevented and injury is avoided an additional cut is possible only by moving the operator arm 32 past the toggle 38 and into the unlatched position as in fig4 two other embodiments of this invention are described in fig7 and fig8 in fig7 the projection mounted onto the blade guard 18 has been supplemented with a handle 40 this handle 40 is also rigidly mounted to the blade guard 18 and operates similarly to the projection 24 in fig1 6 in fig8 the latching piece 42 has replaced the latching mechanism 26 of fig1 7 this latching piece 42 is a one piece combination composed of a cam leg 44 operator arm 46 and blocking means 48 this latching piece 42 is also rotatably mounted to the pin 30 yet because it is one piece motion by one member of piece 42 causes motion of the remaining two members thus if cam leg 44 has been moved out of the path of the pawl 41 of handle 40 the blocking means 48 will move into the.
