Under these conditions the switch arm 26 rests on the flattened cam surface 25 and is thus separated from the fixed contact element 28 depending from the switch box 21. However, when there is a sufficient head of fluid reacting against the face of the flapper valve 22, the pressure will cause said flapper valveto swing toward its open position shown in Fig. 3. The
swinging movement of the flapper valve will tially cylindrical form and having its upper end open and arranged for securement to the'bottom 5 portion of a kitchen sink in registration with the drain opening therein. The lower portion of the container section H1 is slightly outwardly flared and engages a lower casing section II. Within the lower portion of the container section there is secured a cutting or comminuting shell 12 and integral with the lower portion of the casing section II, extending laterally of one side,

predetermined value, whereupon the starting windings cease to function and all of the current thereafter flows through the second set of windings which are the rumiing windings. The above explanation is given in view of the fact that here after we will refer to a magnetic switch which functions automatically to take the starting windings out of play at the proper time and to cause the motor to operate only on the running wind-' ings.
The motor 19 includes a motor shaft 20 which extends vertically upwardly and within the com-' minuting shell 12 the motor shaft 20 has fast thereon a shredder or comminutor 21.
The above general explanation is necessary in order that the present improvements may be appreciated in connection with their association with the elements of the apparatus described. Referring now particularly to Figs. 1, 2 and 3, it will be observed that the opening in the drain extension I3 is rectangular, and adapted to control said opening is a flapper valve 22. The upper end of this flapper valve is cylindrical, as at 22, and is mounted fast on a-shaft 23 journalled through the upper wall of the extension 13. The outer end portion of the shaft 23 has fast thereon a knurled operating knob 24 having an integral, inwardly extending sleeve portion 24 which functions as a cam and has a flattened cam surface 25 thereon. Riding on the cam sleeve 24' is the free end portion of a metallic, yieldable switch contact arm 26. The inner end of the switch arm 26 is anchored to the bottom portion of a switch box 21. When the apparatus is inoperative, or'when there is an insuflicient'head of water reacting against the flapper valve 22 to swing it toward its open position of Said complementary flanges on the members [3 and I4 arev secured together by bolts l5 with an interposed gasketv and extending upwardly from the elbow I4 is a web 16 carrying a horizontal shelf l1 on which are mounted supports for some of the turn the shaft 23 and the cam sleeve 24' to cause a raised portion of the cam sleeve to react against the contact arm 26 to flex it into engagement with the fixed contact element 28, thereby comnism within the casing 21.
pleting the circuit through the switch mecha- The switch mechanism housed within the casing 21 is in fact an on and off switch and is in the electrical circuit to the electric motor I9, current being supplied thereto by means of circuit wires 29 and 30 from the source while wires 3|, 32 and 33 connect with other electrical instrumentalities in the circuit.
. The numeral 34 indicates a reversing switch mounted on the shelf [1. This reversing switch is also in the electrical circuit which is controlled by the on and "off switch mechanism within the casing 21. and 3, said reversing switch has two pairs of yielding contact elements 35 and 36, respectively, with a flexible contact arm 31 between the arms 35 and a flexible contact arm 38 between the arms36. The outer ends of the interposed arms 31 and 38 are joined by a fiber connector 39 which is also engaged by a portion of a band spring 46 whereby, under the influence of the spring 40 the contact arms 31 and 38 will be operated jointly.
' For the purpose of actuating the reversing switch 34 there is mounted on an upright bracket 41 on the shelf 11, a solenoid 42. Ihe solenoid is in the same electrical circuit which includes the on and off switch 21 and the reversing switch 34 and energization and de-energization of the solenoid will cause upward and downward movement of the outer end of a solenoid arm 43 which is mounted for pivotal movement relative to the solenoid and is, when the solenoid is deenergized, normally maintained in the lowered position of Fig. 1 by a coiled spring 44. Swingably depended from the outer end of the solenoid arm 43 is a link 45 whose free end is movably engaged within the elongated curved eccentric slot 43 in an oscillatable ovateactuator 41. The
latter is turnably mounted on a pin 48 projecting Y laterally of the bracket 4|. A peripheral portion of the actuator 41'is provided with a notch in which the free end of the band spring 46 is yieldingly engaged.
When the solenoid 42 is deenergized, which is,
are making contact with the lowermost fixed con-' tacts of the pairs of contact elements 35 and 36. This means that thereafter, whencurrent is supplied to the motor IS, the motor shaft 26 willbeturned in one direction. However, if theactuator As is best shown in Figs. 1'

Waste disposal apparatus including a comminution chamber having an inlet opening and an outlet opening, comminution means including a movable element within said chamber, a reversible motor for driving said element in forward or reverse direction, an electrical circuit for said motor, a reversing switch in said circuit, said switch having an open-circuit position and two closed-circuit positions respectively establishing one or the other directions of motor operation, and switch actuator means in one of said openings operable under conditions of flow through said opening to cause actuation of said switch to one of its two closed positions.
10. In a garbage disposal apparatus having a garbageand water-receiving casing with a comminutor therewithin, a reversible electric motor for driving said comminutor in reverse directions, means forming ingress and egress openings in said casing, an electric power circuit for said motor, a motor reversing switch in said circuit, and flow device means in one of said openings operable when said opening is open for the flow of water to cause actuation of said reversing switch.
11. In a garbage disposal apparatus having a garbage and water receiving casing with a comminutor therewithin, a reversible electric motor for driving said comminutor in reverse directions, a waste material conduit extending from said casing, an electrical circuit including said motor, a motor reversing switch in said circuit, a switch to open and close said circuit, a fluid pressure actuated member in said casing influenced by fluid pressure in said casing and means operably connecting said member to said last-mentioned switch to operate the same in response to fluid pressure actuation of said members.
