compressive strength side view of part c is shown in fig1 b scissorlike part b is designed to allow it to enter hole 23 of part a in either the blade direction first or the handle direction first if one observes and examines a scissors one will find two identical recesses existing near its pivoted section one on either opposite side each of the two recesses is capable of accommodating magnetic part c fig2 a side view shows magnetic parts 15 39 being held in place in recess 28 39 on either side of scissor like part c notice that the recess angle u03b1 39 fig2 is greater than angle u03b1 of fig1 this is to indicate that the angle that sides 26 and 27 make with the side of handle 13 fig1 can vary to make it easier for it to be pulled out by cord 10 by a person on the ground or platform if two magnetic parts 15 39 are employed both for added safety and for greater load capability then two solenoids 22 and 22 39 one installed in either handle 7 39 and 13 39 would be desirable if a restraining cord 9 39 is to be used to prevent removal of magnetic part 15 39 when both solenoids 22 and 22 are energized by pressing switch 11 plungers 19 retract and allow that end of cord 9 39 to fall free enabling the removal of magnetic parts 15 by pulling on cord 10 cord 10 would be tied to both magnets to make it easier to remove magnets 15 39 sides 26 and.
