Abstract

Abstract There is disclosed a waste food disposer having a closure for substantially blocking the throat leading from a sink to a comminutor to prevent ejection of waste food particles. In the open position, the closure does not substantially obstruct the throat of the disposer. A handle is provided for moving the closure between the open and closed positions. The handle is arranged to move the closure from the fully closed position to an intermediate position partially blocking the throat and, after a delay, then moving the closure to the fully open position.

Claim 7
Dependent Claim 124 words
A waste food disposer comprising a comminutor and a conduit including an inlet for providing access between a sink and the comminutor; a closure and means rotatably mounting the closure for movement within the conduit between a first position substantially spanning the conduit, a partially open second position and a substantially fully open third position; means responsive to movement of the closure away from the first position for stopping the comminutor; means for moving the closure between the positions thereof including a handle having a segment extending in the conduit toward the inlet, means connecting the segment and the closure in driving engagement and a lever movably mounted on the segment for engaging the conduit wall and forcing the closure toward the second position.
Claim 8
Dependent Claim 37 words
The waste food disposer of claim 4 wherein the connecting means provides for nondriving movement between the segment and the closure through an arc of movement at least as great as the pivotal range of the closure.
Claim 9
Dependent Claim 101 words
A waste food disposer comprising a housing having an inlet for opening into a sink; means in the housing for comminuting material inserted through the inlet; a closure mounted for sequential movement between a position closing the housing and a multiplicity of increasingly open positions terminating in a substantially fully open position; means for moving the closure from the closed position to one of the increasingly open positions and, after a delay, then to the substantially fully open position; and means for halting operation of the comminuting means in response to movement of the closure toward said one increasingly open position.
Claim 10
Dependent Claim 101 words
A waste food disposer comprising a housing having an inlet for opening into a sink; means in the housing for comminuting material inserted through the inlet; a closure mounted for sequential movement between a position closing the housing and a multiplicity of increasingly open positions terminating in a substantially fully open position; means for moving the closure from the closed position to one of the increasingly open positions and, after a delay, then to the substantially fully open position; and means for halting operation of the comminuting means in response to movement of the closure toward said one increasingly open position.
Claim 11
Dependent Claim 52 words
The subject matter of claim 6 wherein the comminuting means includes a comminuting member and an electric motor for driving the comminuting member; and the halting means comprises a switch controlling a power circuit to the electric motor for deenergizing the motor upon movement of the closure away from the closed position.
Claim 12
Dependent Claim 118 words
