Abstract
Abstract A waste disposer apparatus suspended beneath a sink. Support structure mounted beneath the sink and a mounting ring carrying a waste grinding unit are disengageably hinged at one point of their peripheries so that the grinding unit may be hung from the sink at the initial stage of assembly in a first relatively loose position while plumbing connections are completed. The unit is then swung into position about the hinge and pried into final position. An independent securing means, which also may form a prying tool, is provided for engaging locking means on the support structure and the mounting ring in order to hold the support structure and mounting ring in assembled relationship.
