4 claims. (cl. 1241-251) This inention relates to structures for the reception, disirnegrating, and disposal of kitchen waste. Such structures are now conventionally employed at the discharge oma-ets of kitchen sinks, being suspended thereunder, and are disposed for the passage of culinary Waste from such sinks into grinding chambers in the 'devices in conjunction with ushing water in which the waste is ground and by which it is passed from the disposal structures to available sewage disposal means.

. The object of this invention is to provide simple means for suspending a garbage grinder in cushioned relteionship from the under side of a kitchen sink at the wan: outlet thereof, to provide simple means for enclosing appropriate grinding mechanism, and to pzcvide relarely simple grinding or comminuting means within the apparatus wherein an electric motor is conveniently ployed to eliect the necessary disintegration.

lt is also an object of the invention to provide a simple mount-hg for a splash guard, and a simple splash guard whim may be conveniently disposed in removable 'position al the upper end of the disposal device, where- \fhy such guard prevents splashing back of water and waste particles into the sink and also, in conjunction with hashing water, tends toward elimination of grinding noise which otherwise would pass up from the grind- @g mechanism into the kitchen area about the sink.

Other ocg'ixrs of the invention and various features of construction thereof will become apparent to those skilled in this art npon reference to the following specification and the accompanying drawings wherein certain embodi ments of th: invention are illustrated.

in the drawings:

Fig. l principally a vertical section through a garbage structure of the indicated character and shows suspension thereof from the outlet of a kitchen sink; the section being taken approximately from the line 1-1 or Pig. 2;

Pig. 2 is a horizontal section taken approximately from line 2f-2 of Pig. l;

Fig. 3 is a fragmentary horizontal detail on an enlarge? sle taken on the line 3 3 of Fig. 1; and

Eig. 4 is a similarly en nrged, vertical elevational detail of a portion of the grind ring seen in Fig. l, such elevaion being indicated by the arrow 4 of Fig. 2.

Havin clarence particularly to Fig. l, there-is shown an outer Ncular housing which encloses a waste-re eeh-fing chamber 11 and has connection with a lower motor slfe L2 in which is mounted a conventional elecwlc motor M provided with an upwardly extending drive shaft S. 's'he lower end of the outer housing 10 is provided with an outwardly extending, preferably integral, :lange 4 'which is in turn integral .with a depending housing extension whose lower end is joined to the upper edge of the motor shell 12 through the mediumV o an intervening connecting ring or the like indicated at 16 and having appropriate spacing lugs 15a whose upper porches extend upward somewhat within the lower end ofi1eeftcrsis3n lS behind the joint 18 between Patented June 14,v 1960 Vshell 12 throughany appropriate joint 19, these joints being effected by means of bolts or any othery conventional or preferred form of attachment.

Within the housing extension 15 and the spacing lugs 16a there is positioned a housing 20 which may be integral with the ring 16 and the lugs 16a and carries with in it a grind ring presently to be described, such housing 20 having an integral bottom wall 22 providing bearing means also presently to be described for the motor drive shaft S. Since the grind ring housing 20, in addition to accommodating bearing means for the motor shaft, also acts as a receiver for the comminuted waste and flush water, it is therefore provided with a discharge neck 23 which extends through the intermediate housing ring 16 on one side.

Before describing the grinding or comminu'ting stmoture per se, the means for suspending the structure from a kitchen sink is described. This includes a more or less conventional connection sleeve 25 which is provided at its upper end with an annular, outwardly directed ange 25a that bears upon the upper surllace of the bot tom 26 of the standard kitchen sink or the equivalent. The lower end of the sleeve 25 is externally threaded so that it may receive an internally threaded mounting ring 28 which carries an annular rubber grommet or cushioning member 29 that is externally grooved to receive an inwardly directed integral annular flange 30 at the upper end of the main housing 10 of the apparatus. To retain the rubber gromt-net 29, which acts as a cushioning and supporting means for the ange 30 of the housing 10, the lower outer annular portion of the mounting and locking ring 28 is provided with an integral radially outwardly extending annular flange 31 of snicient extent to underlie, at least partially, the innermost portion of the housing flange 30. Retention of the -grornmet 29 and of the housing ange 30 against upward movement is effected by an overlying binding ring 32 which engages the upper face of the grommet 29 and is retained in such engagement by means of a plurality of anchor screws 33 which are threaded into the ring 28 and have portions of their heads overhanging the binding ring 32. In practice, the mounting and locking ring 28 is threaded upward on the sleeve 25 into engagement with an innermost portionA of an overying lock ring 35 which also is threaded onto the outer wall of the sleeve 25, the two rings 28 and 35 thus binding and locking each other against rotation. in addition, the ring 35 is provided with a plurality of set screws 36 whose heads are adapted to be turned up into engage ment with the under face of an overlying metal washer 37 which is urged. against the under face of an intervening rubber washer 38 which bears against a dependent corresponding portion of the sink bottom 26 around the discharge opening. Thus, by backing the screws 36 out from their threaded seats in the ring 35, the heads thereof force the hard washer 37 upward and compress the rubber washer 33 whereby to effect a good seal and cushion mounting.

It is desirable, as disclosed by the parent cases of which this is a continuationinpart, to provide a flexible splash guard 40 and to mount this splash guard securely, and yet removably, at the lower end of the sleeve 25. This is accomplished in the present instance by providing the periphery of the splash guard 4) with a thickened rib or rim 42 whichis exteriorly grooved to receive an inwardly directed ange 43 provided on the lower'end of the sleeve 2S. Thus, the splash wel 40 may be ieutly produced from rubber preferably slopes downward Yand inward toward its axis to a relatively small central discharge hole 44 to which a plurality of slits 4S lead water being used in conjunction with the grinding of the' waste vmaterial substantially covers and fills the opening 44 and thus materially prevents the passage of noises upward into the kitchen. -ln addition, the upper surface of the grooved rim 42 overlying the ange 43 is provided with asmall upstanding annular bead 46 which provides an annular seat and rest for the periphery of a closure plate or stopper 48 which may have a manipulating handle 49. Thus, the splash guard 40 is renewable by reason of the snap mounting on the flange 43, thereby at the same time providing a renewable sealing seat 46 for the stopper 48.

The grinding mechanism per se, previously mentioned as being carried within the grind ring housing 20, includes a metallic rotor S0, preferably cast, and xed on the upper end of the motor shaft S. Also carried by the rotary mechanism is a top plate $1, which may be perforated as indicated in Fig. 2 for the passage of water, and which is fixed to the rotor 50 as by rivets Sla. In addition, the rotary structure carries a plurality of swinging grinding heads 52 adapted to be swung out into the positions illustrated under the inuence of centrifugal force, and being mounted on axes 53 of bearings 54 (Fig. @extending through the plate 5l and into the rotor S0. As indicated, the outer or swinging portion of each cutting head 52 nses somewhat as it extends rearward in the direction of the arrow of Fig. 2 and provides an arcuate, generally vertical face 55 which tends to urge waste to be comminuted radially outward toward the edges 56 of openings 57 provided in the inwardly offset lower annular portion of a grind ring 58 whose principal body portion 60 is fitted into the upper portion of the grind ring housing 20 and is retained therein by a plurality of bolts 62.

In order to retard rotary movement of waste material .undergoing grinding by the action of the cutter heads 52, the upper or body portion 60 of the grind ring 58 inprovided with a plurality of upstruck cutter and reten tion lugs 63, disposed at an angle of a few degrees to the vertical as best seen in Fig. l. These upstruck lugs 63 are directed toward the approaching cutter heads 52 and the material to be ground, or, in other words, in a direction generally opposite to the direction of rotation indicated by the arrow A of Fig. 2. Such rotation, by the action o f centrifugal force, extends the heads 52 into the positions shown, movement being limited lby stops 61 struck up from the plate 51. Thus, disintegration of the culinary waste is facilitated. Also, the lugs 63 may have lengths approximating the greater part of the width of the mam portion 60 of the grind ring 58, or they may be broken up into shorter lengths in some instances as indicated at 63a. As shown, positioning of the grind ring 58 is yfacilitated by providing the main upper portion 6G of such grind ring with an verhanging outwardly' directed annular flange 64 which may rest upon the top edge of the grind ring housing. lnorder to cushion and seal the upper end of the grind ring housing 20 and of the' grind ring 58, an annular rubber packing ring 65 is positioned under .the shoulder provided by the il'ange 14 in the combination housing 1G, 15, such mbber ring 65 being compressed when the parts are moved into position, and being further retained if desired by an appropriate means such as indicated at 66.

In ad,-rtron.toltheegrind tmeans indlcated, Ithe outer edge of the rotating plate 51 on the rotor 50 is serratedv as shown at 70 in Figs. 2 and 3 so as further to pick up waste material to be ground and to carry such waste material toward the lugs 63 and 63a and particularly toward the cutting edges 56 at the edges of the previously indicated notches S7 best indicated in Fig. 4. The serrations 70 may be irregular-'in and shape, as shown,

some being directed radially inward and slightly for-y ward in the direction of travel and some directedvinward on corresponding radii. By these means, a very satis factory and relatively inexpensive shredding or comminuting mechanism is provided. g r- As seen in Fig. 1, the periphery ofthe cast rotor 50 is in general provided with a ldepending annular flange 74 which insures vcarrying down shredded material and ushing wateronto the or 22 of' the grind ring housing.

20, whence the hushed material and water escape through the discharge neck 23.

As previously indicated the rotor S is bound upon the upper end of the motor shaft S, and this may be effected by threading a central hub portion ofthc rotor 50 upon :he upper end of the shaft S and binding the parts together through a lock nut 7S.y As shown, the intermediate portion of the exposed shaft end S is shouldered to receive a conventional roller bearing cornbination 75. The passage of lubricant from the bearing combination 76 downward is 'prevented by a pair of sealing rings 77 and 73, the former of which is snapped into the inner wall of the hub portion 80 of the door 22 of the grind ring housing 20 and the other of which is carried in co-operau've relation von the mentioned shoulder of the shaft S below the bearing combination 76. For the purpose of exclusion of water and waste material from the shaft S, an upstanding hub portion 82 of the mentioned floor 22 is provided with a snap-in disc 84, the inner edge of which tno-operates with an. nular packing material 85 on the adjacent under face of the rotor 50. Additionally, another disc 86 attached to the hub portion of the rotor 50 is provided, this disc 86 having a downturned annular flange 88' which is i directed into 'an annular depression 99 between the spaced hub portions and 82 of the grind ring housing 20. By these means entrance of water. to the bearing combination 76 is effectually prevented, and similarly loss of lubricant about the bearing combination 76 is eectively avoided. Also the washer means consisting of the snap ring 77 and the washer. 78 effectively prevent axial movement of the bearing combination 76.

Thus, eiiicient, and at the same time relatively inexpensive, mounting means, driving means, grinding means and suspension means for culinary waste disposal uses are conveniently provided. At the same time the particular means is provided for mounting and renewing the splash guard 40 which serves also to provide an adequate and renewable seat 46 for the stopper 48.

Since the plate 5l of the rotor structure, the grind rin 58, and the outer housing 10, 14 and' 15 may bc formed of sheet steel, their fabrication is simple.
