of essentially flat rectangular configuration and has a rubber or plastic coating to prevent corrosion within the water closet 12 upper magnet 78 constructed of conventional magnetic iron is of configuration similar to magnet 76 and likewise has a rubber or plastic coating to prevent corrosion within water closet 12 magnet 78 is shown in fig2 in magnetic contact with lower magnet 76 through magnet covers 77 and 79 upper magnet bracket 80 is rigidly joined by the use of screws not shown or other suitable attachment to upper magnet 78 at surface 82 arm 84 of bracket 80 is extended and has a slot 85 through which piston rod 66 extends thereby maintaining proper alignment of the upper magnet bracket 80 during use as will be hereinafter described restraining rod 86 is threaded into or otherwise suitably joined to upper magnet bracket 80 with continued reference to fig2 slide bracket 90 is rigidly joined to piston rod 66 and guide rod 74 by means of bolt 92 maintaining piston rod 66 and guide rod 74 in substantially co parallel positions piston rod 66 has a dogleg 93 positioned opposite bolt 92 to facilitate attachment of slide bracket 90 to piston rod 66 portion 88 of slide bracket 90 forms a sleeve through which restraining rod 86 passes in free movement relationship restraining rod 86 is thus maintained in a substantially co parallel position with piston rod 66 and guide rod 74 catch nut 98 is adjustably positioned on threads 100 of restraining rod 86 and selectively engages slide bracket 90 during use as will be hereinafter described more fully a loop 94 is rigidly joined to lower surface 96 of slide bracket 90 between the piston rod 66 and guide rod 74 loop 94 serves as.
