Definitions

  • This invention relates generally to food waste disposers and, more particularly, to an improved means to support a food waste disposer from a sink such that the disposer is secured against undesirable rotation relative to its support.
  • Food waste disposers are most commonly supported from, and in communication with, the drain opening of a kitchen sink which opening serves as an ingress opening for the admission of the waste material and water to the comminuting apparatus.
  • the disposer itself is most often positioned in a relatively inaccessible location, viz., within the cabinet below the sink. In the past this made the installation and removal of the disposer an awkward chore, especially if the disposer was a relatively heavy one. It often required the efforts of two workmen to properly install or remove a disposer from its location beneath the kitchen sink.
  • Patent 3,108,755 issued to us on October 29, 1963 and assigned to the General Electric Company, assigneeof the present invention, we describe and claim a support system for a food waste disposer which overcomes the aforementioned problems and which allows a single workman to install or remove a food waste disposer with relative ease.
  • the present invention has broader application, it is particularly suitable for use with the arrangement disclosed in the aforementioned US. Patent 3,108,755.
  • a system to support a food waste disposer below a sink wherein the disposer includes a housing having therein an opening to be connected to external plumbing. Means are provided to support the housing below the sink such that the housing may be rotated at least a few degrees about a substantially vertical axis to bring the opening into registry with the external plumbing.
  • the means supporting the housing has at least one tab projecting therefrom and the disposer housing has a plurality of angularly spaced catches adapted to engage the tab upon rotation of the disposer housing relative to the support means. The tab and catches are arranged so that the tab will interfere with the catches in one direction of rotation of the dis poser housing to thereby prevent said rotation.
  • the tab and catches are further arranged so that the catches will freely allow the tab to pass in the opposite direction of rotation of the disposer housing.
  • the direction of rotation of the housing whereby the tab interferes with the catches to prevent rotation is the direction of rotation of the rotary comminuting means within the disposer when the disposer is operating.
  • the disposer may be positioned below the sink so that the weight of the disposer is placed upon the support means and the disposer may then be rotated to bring the opening in the disposer housing into registry with the plumbing to which the opening is connected.
  • FIGURE 1 is a partial elevational view partially cut away to show details of a food waste disposer employing the present invention
  • FIGURE 2 is a partial sectional view taken along line 2-2 of FIGURE 1;
  • FIGURE 3 is a sectional view taken along line 33 of FIGURE 1;
  • FIGURE 4 is a perspective view of a portion of the support means of the present invention showing details thereof.
  • a food waste disposer 10 including an upper housing 11 defining a comminuting chamber 12 and a lower housing 13.
  • the comminution of waste material takes place near the bottom of comminuting chamber 12 and any suitable comminuting means may be used to effect the comminuting operation.
  • the comminuting means may be used which is described and claimed in US. Patent No. 2,828,083 issued March 25, 1958 to H. J. Macemon, and assigned to the General Electric Company, the assignee of the present invention.
  • the comminuting means comprises a stationary shredding ring 14 which is provided with cutting surfaces 15 and with a plurality of apertures 16.
  • a material impelling flywheel 17 Co-acting with the shredding ring 14 is a material impelling flywheel 17 which is provided with a pair of impellers 18 arranged, upon rotation of the flywheel, to impel the waste material against the shredding ring 14 to comminute the material into a fine mass. It will be understood that during the operation water will be caused to flow down through the comminuting chamber 12, and that eventually the water and the comminuted material constituting a flowable mass will be discharged through the apertures 16 into a drain chamber 19 which communicates, by means of outlet opening 20, with a drain leading to the sewer system of the house.
  • the flywheel 17 is driven by a suitable electric motor 21.
  • housing 11 includes an opening through which the waste material and the water is supplied to the comminuting chamber 12 from a drain opening 22 provided in the household sink, the bottom wall of the sink being designated by the numeral 23.
  • Means for supporting the disposer from the wall 23, as best shown in FIGURE 2 comprises a cylindrical tubular sleeve 24 which is arranged to be inserted down through the drain opening 22 and at its upper end is provided with an outwardly extending annular flange 25 adapted to overlie an annular marginal edge 26 of the drain opening 22.
  • the marginal edge 26 is slightly depressed from the bottom wall 23.
  • the lower end of the sleeve 24 is provided with an inturned flange 27 which is adapted to support a splash guard 28.
  • the splash guard 28 is, in turn, adapted to support a suitable sink stopper 29.
  • the sleeve 24 not only functions to conduct the waste material and water into comminuting chamber 12 but also constitutes a support means for the disposer 10.
  • sleeve 24 is rigidly secured to the bottom wall 23 of the sink. This is accomplished by a support ring 30 which encircles the sleeve 24 and cooperates with a snap ring 31.
  • the snap ring 31 nests in an annular recess 32 in sleeve 24.
  • the inner peripheral portion 33 of the support ring 30 is shaped to seat upon snap ring 31 so that as supporting ring 30 tends to move downwardly, it engages snap ring 31 such that it prevents snap ring 31 from expanding while at the same time, snap ring 31 prevents downward movement of the support ring 30.
  • Support ring 30 is provided with a plurality of spaced threaded openings each of which receive a bolt 34.
  • Bolts 34 function to clamp the flange 25 to the marginal edge 26 of the sink by means of a clamping ring 35 encircling the sleeve, it being understood that when the bolts 34 are screwed upwardly they will sandwich the marginal edge 26 between the flange 25 on the sleeve and the clamping ring 35.
  • a ring gasket 36 encircling the sleeve 24 will be inserted between the bottom of the sink and the clamping ring 35.
  • the support ring 30 also serves to attach housing 11 to the sleeve 24.
  • a plurality of slot patterns each including an inner slot 37 and an outer slot 38, are conveniently spaced from the circumference of the support ring 30.
  • Each of these slot patterns receives a clip 39.
  • the clips 39 can best be described as generally S-shaped and each includes a resilient central portion 40 and a bent over upper portion 41.
  • the upper portion 41 is provided with a pair of tabs 42 which engage the bottom surface of support ring 30 to resiliently secure clip 39 to the support ring 30.
  • the resilient central portion 40 terminates with an upwardly turned free end 43.
  • gasket 44 Surrounding the upper portion of housing 11 is a gasket 44 which is provided with a surface 45 adapted to rest upon the free ends 43 of clips 39 when the disposer is in its normal installed position as shown in FIGURES 1 and 2. It will be observed that gasket 44 engages the outer surface of the sleeve 24 to provide a liquid tight seal between housing 11 and the sleeve 24.
  • the gasket 44 is preferably constructed from a relatively resilient material.
  • a clamping band 46 encircles the lower portion of gasket 44 and is preferably of a length sufficient to extend below the surface 45 of gasket 44 to provide a means of assuring that clips 39 are prevented from flexing outwardly beyond surface 45 when the disposer is in its installed position.
  • Bolts 34 are then screwed up through support ring 30 into engagement with clamping ring 35 to the extent that the assembly is rigidly secured to the bottom wall 23 of the sink.
  • the food waste disposer having gasket 44 and clamping band 46 attached thereto, is brought into alignment with the sleeve 24 from below.
  • the disposer is then raised vertically until the upper portion of the gasket 44 comes into contact with the free end 43 of the clips 39.
  • the clips 39 are biased outwardly and then downwardly beyond the bottom extremity of the clamping band 46 whereupon they snap radially inwardly to become positioned directly below surface 45 of gasket 44.
  • the disposer When this has been achieved, the disposer is moved vertically downwardly until surface 45 rests upon free ends 43 of clips 39. At this point, food waste disposer 10 is in its normal installed position with regard to vertical relationship with the sink. If outlet opening 20 has been maintained in proper alignment with the plumbing to which it is to be connected during vertical movement of disposer 10, installation of disposer 10 is substantially completed. However, it is not always convenient to maintain outlet opening 20 in proper alignment with the external plumbing during the aforementioned manipulations of disposer 10 and therefore it is usually necessary to rotate disposer 10 a few degrees about its axis to bring opening 20 into registry with the external plumbing.
  • means are provided which still allows the aforementioned limited relative rotary movement between disposer 10 and sleeve 24 but further provides means to prevent rotary movement of the disposer relative to the sleeve 24 due to jamming and shock loading of the comminuting assembly within the disposer.
  • flywheel 17 rotates in a counterclockwise direction when viewed from the top.
  • Impellers 18 rotate with flywheel 17 and effect a comminuting action of food waste within chamber 12 by cooperating with cutting surfaces 15.
  • certain materials are being comminuted such as for example bones, it is possible for the material to work its way into a position relative to impeller 18 and cutting surface 15 such that jamming occurs. Under certain conditions, the jamming may be sufficient to completely stop rotation of flywheel 17.
  • each of the clips 39 is provided with a tab 47 lanced out from the central portion 40.
  • Tab 47 projects outwardly from central portion 40 on the side which faces clamping band 46 when disposer 10 is installed as shown in FIGURE 1.
  • Groups of catches are provided on the outer surface of clamping band 46.
  • FIGURE 3 there are four groups 48, 49, 50 and 51 of catches with each group positioned adjacent a clip 39.
  • the catches are all configurated so that clamping band 46, and disposer 10 which is secured thereto may be rotated relative to clips 39 in one direction of rotation but not in the opposite direction of rotation.
  • the central portion 40 of clip 39 is resilient which will thereby allow clip 39 to flex outwardly as the catches pass by the tabs 47 in the one direction of rotation.
  • Groups 48 and 50 are diametrically opposed from each other while groups 49 and 51 are diametrically opposed to each other. It has been found in practice that a convenient spacing for the individual catches in any group is approximately 5". That is, in any given group a catch is angularly spaced 5 from the catch adjacent thereto. Careful scrutiny of FIGURE 3 will reveal that groups 48 and 5b are not exactly spaced 90 from groups 49 and 51. As shown in FIGURE 3, tabs 47 are in contact with a catch in each of groups 48 and 50 while tabs 47 are intermediate the catches of groups 49 and 51. It has been found in practice desirable to off-set groups 48 and 50 from groups 49 and 51 by 2 /2 from the cardinal 90 spacing.
  • This olf-set provides a stepped arrangement whereby groups 48 and 50 will be in engagement with tabs 47 at one position of disposer 10 and groups 49 and 51 will be in engagement with tabs 47 when the disposer is rotated 2 /2 from the previous position.
  • the configuration of the catches is such to prevent rotation of disposer 10 when the above-mentioned jamming or shock loading of flywheel 17 occurs.
  • the arrangement allows disposer 10 to be rotated in the opposite direction at least several degrees during installation of the disposer to bring opening 20 into registry with external plumbing.
  • tabs 42 which serve to secure clip .39 to support ring 30, provide limited flexibility so that during operation of the disposer 10 when a shock load occurs, the catches do not tend to bounce after contact with tabs 47. If this flexibility were not present it is possible, under extreme shocks, for the catches to bounce back and actually result in the disposer rotating one notch in the direction opposite to the shock load.
  • a system to support a food waste disposer below a sink comprising:
  • a system to support below a sink a food waste disposer having a housing with an opening therein to be connected to external plumbing comprising:
  • said means on the disposer housing having a plurality of angularly spaced catches adapted to engage said tab and thereby limit rotation of the housing in one direction.
  • a system for supporting a food waste disposer below a sink said disposer having a rotary comminuting means, said system including support means depending from said sink to secure said disposer against vertical movement but adapted to allow at least limited rotary movement about a substantially vertical axis, said disposer including a housing having an opening therein to be connected to external plumbing, an improvement to allow alignment of said opening with said plumbing during installation of said disposer but to prevent subsequent rotary movement of said housing to thereby minimize stress on the connection between said opening and said plumbing comprising:
