• the threaded reed switch collar 24 has molded into an inside tubular geometry a plurality of bayonet type dimple attachment recesses 38, 38' molded in and matching the geometry and the plurality of the outward protrusions 8 of the sink-flange 4 as a means of securely attaching the threaded reed switch collar 24 to the sink-flange 4.
• the threaded reed switch collar 24 includes at least two bayonet dimple insertion tracks 40, 40' that are transversely oriented and lead into individual ones of the bayonet type dimple attachment recesses 38, 38'.
• the bayonet dimple insertion tracks 40, 40' are non-symmetrical (meaning they are not oriented at even angular intervals such as 180 degree intervals), to allow a magnetic strainer 42 to be inserted into the sink-flange 4 in only one pre- designed location orientation.

Substantial alignment occurs with approximately 50% or more overlap of the individual magnets 50 with individual ones of the magnetic reed switches 46.
• the quantity and geometry of the magnets 50 and reed switch positions 52 are such that by the rotation of the magnetic strainer 42 in its appropriate internal dimple channel 54, the reed switches 46 will be activated either to an "on" position 56 or an "off” position 58 as pairs, providing a redundant switch as a security device.
• This switching can be designed as a single or as multiple modes of operation by utilizing multiple reed switches 46 and geometries.
• a resilient material bumper 60 is provided acting as a detent to releasably hold the "on" position 56 to prevent normal vibration of the waste disposer from inadvertently shutting off the unit.
• the magnetic strainer 42 includes channels 54 about a strainer periphery 62, which correspond to the geometry of the inner dimples or inward protrusions 12 of sink-flange 4, allowing the sink- flange 4 to track in engineered locations or channels and stop in predetermined tracks. These locations are pre-designated magnet 50 and reed switch 46 "on” 56 or "off” 58 positions.
• the magnetic strainer 42 includes one or more parts including a top 64 and a bottom 66 that can snap together using one or more deflectable engagement tabs 68 and can snap apart to help make cleaning easier.
• the magnetic strainer 42 has at least two dimple insertion tracks 70 that are non-symmetrical which allow the magnetic strainer 42 to be inserted into the sink-flange 4 into only one pre-designed location orientation.
• a sink flange gasket 72 of a resilient material includes a plurality of waves or ridges 74 in opposed surfaces to create a fluid seal.
• the sink flange gasket 72 can be used to mount the sink-flange 4 to provide a fluid seal and to further isolate a noise and vibration path from the food waste disposer 76 shown in Figure 19 to the sink 26.
• a snap ring 78 snap engages into a circular shaped channel 80 of the threaded reed switch collar 24.
• Snap ring 78 includes a plurality of extensions 82 which engage with individual ones of the reed switches 46 to retain the reed switches 46.
• a reed switch mounting post 84 extending from an inner wall 85 of threaded reed switch collar 24 is also provided at each mounting location of the reed switches 46.
• Channel 80 also provides a routing path for the individual ones of the reed switch wires 48 of the reed switches 46, and a plurality of slots 86 are created in threaded reed switch collar 24 to permit exit of the reed switch wires 48.
• a plurality of notches 88 created in snap ring 78 are alignable with individual ones of the slots 86 to provide additional clearance for the reed switch wires 48.
• another embodiment of a food waste disposer mounting system 90 reduces noise transmission of motor noise of the disposer via a path to the sink flange.
• a polymeric material sink flange 92 is positioned in a sink 94 (only partially shown).
• a washer 96 positioned above an upper sink face 98 is compressed against the sink face 98 by threadably engaging a threaded collar nut 100 which engages a plurality of threads 102 created on an outer tubular body portion 104 of sink flange 92.
• a flange mount 106 is slidably received over outer tubular body portion 104 below the threads 102 and a mount retaining ring 108 is located below the flange mount 106.
• Mount retaining ring 108 can be diametrically spread to pass over an extending lip 110 formed at a free end 112 of the sink flange 92.
• Mount retaining ring 108 is frictionally received within an annular groove 114 formed above and proximate to extending lip 110.
• a cladding ring 116 of a metal material such as a stainless steel can be shape-formed corresponding to a shape of and frictionally coupled over an annular flange 118 of sink flange 92.
• sink flange 92 includes outer tubular body portion 104 which is homogenously connected to annular flange 118.
• the plurality of threads 102 are co-molded with and extend outwardly from outer tubular body portion 104.
• threads 102 are left-handed threads.

• a disposer attachment body flange 124 connected to a disposer unit 126 (only partially shown) is rotated in a clockwise rotation "Z" to engage disposer unit 126 to disposer mounting system 90 and sink 94.
• the clockwise rotation of disposer attachment body flange 124 acts opposite to the rotation of threaded collar nut 100 so threaded collar nut 100 is not loosened by installation of disposer unit 126.
• a ring 128 extending radially from disposer attachment body flange 124 can contact an arm 130 radially extending from flange mount 106 to limit rotational travel of disposer attachment body flange 124 with respect to flange mount 106.
• the installation sequence is as follows.
• Sink flange 92 is aligned within an opening 132 in sink 94 so that annular flange 118 contacts an upward facing surface 134 of washer 96.
• Washer 96 has an annular bore that allows washer 96 to be slid outside of threads 102 until washer 96 abuts annular flange 118.
• Threaded collar nut 100 is threaded onto threads 102 and rotated until washer 96 is compressed against the sink face 98.
• the flange mount 106 is then slidably pushed over extending ring 110 and over outer tubular body portion 104 up to the threads 102 until flange mount 106 abuts or is positioned proximate to the threaded collar 100. While temporarily holding flange mount 106 in position, mount retaining ring 108 is then elastically diametrically spread to slide past extending ring 110 at free end 112 of the sink flange 92 and seats within by biasing into frictional contact within annular groove 114. A rolled portion 136 of mount flange 106 which defines an inner diameter smaller than a diameter of mount retaining ring 108 thereafter retains flange mount 106.
• Mount retaining ring 108 can be made from a metal material to provide shear load support to prevent removal of flange mount 106 by gravity/weight load induced by the disposer unit on the sink flange 92.
• a disposer (not shown) is positioned abutting flange mount 106.
• the disposer attachment body flange 124 is then rotatably engaged with flange mount 106.
• Disposer attachment body flange 124 is rotated in a clockwise direction to tighten disposer attachment body flange 124.
• a food waste disposer mounting assembly of the present disclosure provides several advantages.
• the mounting assembly uses a stainless steel or plastic sink-flange with a screw-on collar system as its primary mounting system.
• a stainless steel or plastic sink-flange with a bayonet locking reed collar and screw on nut collar By using a stainless steel or plastic sink-flange with a bayonet locking reed collar and screw on nut collar, a path for vibration and sound transmission to the sink is both smaller and rendered indirect. Both vibration and motor grinding noise are reduced.
• the system can also accommodate reed switches so a stopper with magnets turns the unit into a batch-feed disposer.
• Stainless steel flange of the present disclosure eliminates a direct connection from the disposer to the sink, and can accommodate various sink thicknesses.
