Claims. (Cl. 241-100.5)
In general this invention relates to apparatus of the household and restaurant type for disposal of garbage and kindred waste frequently referred -to as garbage grinders.
More particularly the present invention relates to means for mounting such apparatus by suspension from kitchen sinks and the like.
A particular object of the invention is to provide novel and eflicient means for freely suspending a garbage grinder at the discharge opening of a kitchen sink or similar water discharging vessel so that vibration generated in the usaul garbage grinding unit is absorbed, thereby preventing the transmission of such vibration to the plumbing system of the building in which the apparatus is used and to thebuilding itself.
A more particular object of the invention is to employ resilient means continuously under tension, such as' a rubber sleeve which suspends the garbage grinder, whereby to effect absorption of vibration from the device.
This application is a continuation-in-part of my application Serial No. 351,270, filed April 27, 1953, which in turn is a continuation-in-part of my application Serial No. 248,002, filed September 24, 1951, and now Patent No. 2,73 0,308, of January 10, 195 6; and is also a continuationin-part of my application Serial No. 190,927, filed October 19, 1950, now abandoned.
The principal features of the invention and other objects thereof will become apparent to those skilled in the art upon reference to the accompanying drawings and the following specification wherein various embodiments of the invention are illustrated.
In the drawings:
Fig. 1 is principally a vertical section through a more or less conventional garbage grinding device, suspension means of the present invention being shown in vertical section, this view also showing means for cushioning a discharge connection leading from the grinder discharge to the plumbing system;
Fig. 2 is a vertical section through an alternative form of the waste disposal device of this invention; and
Fig. 3 is a graph illustrating the noise damping effect of the present invention.
With particular reference to Fig. 1, there is shown a garbage grinder housing which includes a lower motorcontaining shell 20 and an upper casing 21 provided with an upstanding receiving neck 22, such housing 21 containing a two-part grind ring 23 and a turntable 24 driven by a motor within the shell 20 and having movable grinding heads 25 which cooperate with grinding lugs 26 on the ring 23 a discharge connection 28 leading from the upper portion of the shell 20 to dispose of comminuted waste material.
The structure is illustrated as being suspended from a sink bottom 30 through the medium ofa discharge sleeve 32 provided at its upper end with an outwardly extending flange 33 borne upon a tapered seat 34. This sleeve 32 extends through a corresponding opening in Patented July 1 1960 ice the sink bottom 30 adjacent a depending short neck 30a of the sink bottom. The lower end of the sleeve 32 is threaded as indicated at 35 for the purpose of threadedly receiving an annular connecting ring 36. An upstanding hub 36a bears against a metal washer 37 upon which rests a sealing washer 38 of rubber or other compressible material which is forced up into sealing engagement with the short neck 30a of the sink bottom 30 by tightly turning up the connecting ring 36. Projecting radially from the connecting ring 36 at a plurality of points, which points in practice are three in number, are attachment ears 36b.
Underlying the connecting ring 36 and engaged therewith is a depending resilient tensioned rubber suspension ring 40 which, in the form of Fig. l, is held in position through the medium of headed screws or bolts 42, which preferably are also threaded into the ears 36b. The lower ends of the screws 42 receive washers 43 to be retained in set position by nuts 44 on the lower ends of the screws. The inner edge of each of these washers engages with outwardly projecting portions of a steel or other metallic ring 45 which is embedded and vulcanized in the resilient rubber ring 40. Thus, by tightening up the nuts 44, the washers 43, through engagement with the metallic ring 45, force the suspension ring 40 tightly up against the under side of the connecting ring 36. To insure proper positioning and good sealing, the top of the rubber ring 40 is provided with an annular upstanding bead 40a which is received in a corresponding groove in the under side of the connecting ring 36. Compression of the portion of the rubber of the ring 40 lying above the metallic ring 45 which is eflfected by tightening up the nuts 44 as stated preferably should be limited, so that'not all of the resilience is taken out of the rubber by compression. To effect limitation of the compression, stop means is provided. In the structure shown in Fig. 1 this stop means is in the form of a depending l ug or flange 46 integral with each roughly semi-circular ear 36b, the disposition of this flange 46 being such that it engages the respective washer 43 when its nut 44 is moved up to the limit of compression desired.
In order that the rubber packing ring 38 above the washer 37 may be properly compressed against the short neck 30a of the sink bottom 30, the head of each screw 42 may be raised by backing it out with a wrench until it engages the corresponding outer edge portion of the metallic washer 37 to exert such pressure as is required.
By securing the lower end of the resilient suspension ring 40 to the topof the neck 22 of the grinder housing 21, the weight of the grinding device thus places the intermediate portion of the resilient ring 40 in tension so that the grinding device is freely suspended upon the resilient rubber mounting and transmission of vibration from the grinding mechanism to the sink bottom 30 is prevented. Satisfactory means to effect this attachment are shown in Fig. 1 as a second steel or other metallic ring: 48 embedded and vulcanized in the lower portion of the resilient ring 40, and a steel snap ring 49 snugly mounted in a corresponding groove in the thickened upper end portion of the neck 22 of the grinder housing. The two rings 48 and 49 are apertured at suitably spaced points, such as three points, to receive corresponding bolts 50 whose nuts 51 effect a proper tensioning of a portion ofthe rubber between the top of the neck 22 and the ring 48. In order to limit compression of the rubber at this location, stop means such as thick metallic sleeve 52 may be employed. In the preferable form of.
construction the resilient suspension ring 40 is molded with an integral, inwardly directed, downwardly sloping diaphragm 54 which is slit as indicated at 55 to provide a plurality of yieldable fingers so that objects to be disintegrated may be introduced into the grinder chamber up to the size of the throat through the discharge sleeve 32 and the housing neck 22. In the preferred form, a central opening 56 is provided in the diaphragm 54, the diameter to this opening preferably being approximately one-tenth or one-eighth of the diameter of the throat through the sleeve 32 and the neck- 22 so that it will be substantially closed by water which is fed from the sink 30 into the grinding chamber during grinding operations. When a body of water is required in the sink, a stopper shown at 58 is used, this stopper resting upon an inturned seat 59 integrally provided on the lower end of the sleeve 32. For the purpose of introduction of garbage and an adequate supply of water into the grinding chamber, the stopper 58 is removed. When water is flowing, the diaphragm 54' acts as an anti-splash device and together with the water filling the small opening 56 serves as means to reduce transmission of noise from the grinding means.
. Fig. 2 shows an alternative form of waste disposal device 60 adapted to be suspended from a sink, drain board, or the like 61, having an opening 62 therein.
The disposal device 60 generally includes suspension means 64, vertical hopper means 65, rotatable comminuting means 66, and power means 67 operatively connected to the comminuting means and adapted to actuate the same.
The suspension means 64 includes a tubular inlet sleeve 70 having an annular upper flange 71 which is adapted to rest on and be supported by the sink 61. The sleeve 70 is provided at its lower end with an inturned annular bead 72 providing a seat for a stopper 73 and an external annular groove 74 which receives a substantially circular snap ring 75 which in turn supports an upper annular ring mount 76 provided with a plurality of circumferentially spaced threaded openings 77, preferably three in number, each of which receives a screw 79. Beneath the ring mount 76 is provided a clamp ring 80 provided with a plurality of openings 81 vertically aligned with the threaded openings 77 but of a larger size, each of which receives one of the screws 79, the clamp ring being supported on nuts 82 threaded onto the screws. The clamp ring 80 supports a ring member 83 upon which rests a head 84 of a tubular sleeve member 86 formed of rubber or other elastomeric material. The lower end of the resilient sleeve member 86 is provided with an annular shoulder 88 upon which rests an inwardly extending flange of a lower clamp ring89 having an inwardly extending lower flange 90 which fits under an external peripheral bead 91 formed on the upper end of a generally conical 'upper housing member 92 of the hopper means 65. The sleeve 86 provides a continuous intermediate portion substantially longer than its average wall thickness.
Connected to the lower end of the upper housing member 92 is a central housing member 94 and clamped therebetween is an annular grind ring 95, the central housing member providing an annular discharge chamber 96 and a discharge outlet 97 connected thereto. To the lower end of the central housing member 94 is connected a motor shell 98 housing an electric motor (not shown) which is connected by a drive shaft 99 to the rotatable comminuting means 66.
The comminuting means 66 includes a dish-shaped table member 101 which is rigidly supported on the upper end of the drive shaft 99 and is provided with impellers or comminuting elements 102, a plurality of which are preferably spaced around the periphery of the table member and co-operate with projections 103 on the inner wall of the grind ring 95 so that when the table member is rotated by themotor the comminuting elements cooperate with the projections to comminute waste material H therebetween. The comminuted material passes downwardly through suitable ports in the grind ring or between the table member 101 and the grind ring 95 and into the discharge member 96 from which it passes into the discharge outlet 97, as is well-known in the art.
From the foregoing it will be apparent that this invention embraces several usable means of mounting the upper and lower ends of resilient, shock-absorbing suspension rings between. a sink outlet and a suspended grinder housing, so that intermediate portions of the resilient rings are solely under tension, thereby freely suspending the respective grinders and preventing transmission of vibrations and kindred influences to the overlying sink and building construction in which it is installed.
The graph shown in Fig. 3 provides a quantitative comparison of the results produced by the present invention in comparison with those produced by a conventional waste disposal device without the incorporation of the present invention. The graph shows the sound level in decibels plotted against vibration frequency in cycles per second. The curve 104 shows the noise level of a waste disposal device in all respects identical with that shown in Fig. 2, but with the substitution of a rigid connection between the hopper means 65 and the inlet sleeve 70 for the resilient suspension means 64. The curve 105 shows the noise level of the waste disposal device of Fig. 2. From the curve 105, it will be apparent that a substantial amount of the noise producing vibrations between about 100 and 1700 cycles per second has been reduced by the addition of the resilient inlet sleeve 86. It will be apparent from the graph of Fig. 3 that in a conventional unit a large part of the low frequency noise producing vibrations is transmitted directly from the unit to the sink and surrounding walls, which, incidentally, act as a sounding board. The resilient mounting tension of thereof may be modified without departing from the spirit of the invention, and I desire to be afforded the full scope of the following claims.
