MOUNTING ASSEMBLY AND METHOD FOR FOOD WASTE DISPOSER Abstract of the Disclosure A simplified mounting and sealing assembly for rapidly attaching a food waste disposer to a sink includes a sink flange which is inserted into the drain opening in the sink and has an elongated neck extending below the sink. An annular pressure plate is received on the flange neck below the sink, and is tem- porarily supported by bosses or protuberances on the flange while also capturing the flange in the sink opening. An annular groove is formed in the flange neck below the bosses and a snap ring which is held captive in the disposer engages this groove upon lifting the disposer over the neck. The groove and snap ring hold the disposer on the flange so it is free to be rotated for making electrical and drain connections. An annular flange seal is received in the disposer and an annular compression plate rests on the upper surface of this seal. Jack screws extend between this annular compression plate and the pressure plate to lift the annular pressure plate against the bottom of the sink, compress the annular seal and lock the disposer against movement. The jack screws are threaded into the compression plate and force it down- wardly against the seal to cause the seal to engage both the neck of the flange and the disposer at the same time that the pressure plate is lifted up against the bottom of the sink. The arrange- ment is such that extending the jack screws to lift the pressure plate and compress the flange seal does not alter location of the disposer with respect to the sink or previously completed plumbing- electrical connections.
