22 Claims.
This invention relates to improvements in garbage disposal apparatuses, and more particularly to a garbage disposal device attached to a kitchen sink in registration with the drain thereof.
A general object of the present invention is to pipes.
A further object of the invention is to provide a garbage disposal apparatus for kitchen sinks interposed in the sink drain pipe below the sink outlet, novel means being provided in the apparatus for expeditiously and effectively grinding, mashing and reducing all forms of garbage whereby the reduced garbage can be flushed through the drain connections and into the sewer by the flow of tap water.
A further object of the invention is to provide a garbage disposal apparatus of the character described having a novel form of rotary cutting member therein operable in reverse directions by a reversible electric motor, the apparatus being substantially automatic in operation whereby handling of garbage for disposal is reduced to a minimum.
A further object of the invention is to provide a garbage disposal apparatus of the character described equipped with a novel and effective form of drain stopper or valve for the sink to which the apparatus is applied.
A further object of the invention is to provide a garbage disposal attachment for kitchen sinks which is easy to operate, which is clean, sanitary and eflicient, which is stron'g and durable, which is compact, 'and which is well adapted for the purposes set forth.
With the above and other objects in view, the invention consists of the improved garbage disposal apparatus, and its parts and combinations as set forth in the claims, and all equivalents thereof.
In the accompanyingdrawings in which the same reference characters indicate the same parts -'in all of the views:

\ ,Fig. 8 is a perspective view, partly broken away and in section, of the comminuting wall of the apparatus; and
Fig. 9 is a developed view of the member of Fig. 8 to illustrate the formation of the cutting grooves.
Referring now more partcularly to the drawof a refuse container of substantially cylindrical form having at its upper end an annular flange i8 secured to the nut It by bolts I! with an interposed fibrous material gasket 20. The heads of the bolts l9 are counter-sunk into recesses 2| therefor in the nut i6, while the lower ends of the bolts carry standard nuts 22. 4
Adapted for removable and adjustable seating within. the" drain neck l5 which is internally downwardly tapered, is a stopper member 23 which is generally in the form of an inverted basket of circular contour. Said stopper memberis imperforate and when sink drainage is to take place, it is intended that such fluid drainage be between the outer periphery of the stopper member and the inner wall of the drain neck It, retractable means being provided on the stopper member for holding it in a seated but spaced relationship for this purpose. Said means comprise a plurality of outwardly Projecting arms 26. A rotatable operating shaft 25 extending axially into said stopper member has a disc 25 fast on its inner end portion. The inner end of each arm 2 5 is bifurcated to embrace a peripheral portion of said disc to which it is attached by a pivot pin 21, and the inner surfaces of said bifurcated end are beveled as at 28 and shouldered as at 29 for the purpose of limiting -projection and retraction of the arms upon turning of the disc, it being evident that upon. turning of the disc to project the arms, as in- Figs. 1 and 3, movement is ultimately limited by the high portions of the beveled surfaces 28 binding against the disc, while upon turning movement of the disc to retract said arms, as in Fig. 4, movement is ultimately arrested by engagement of the arm shoulders 29 with said disc.
Manipulation and operation of the stopper is facilitated by a knob 30 fast on the outer, upper end portion of the shaft 25. The operation and use of said stopper in conjunction with the sink outlet opening and the drain neck is as follows: When the sink outlet is to function in its normal manner for the outflow of liquid, the stopper arms 24 are projected as in Figs. 1 and 3 to im-' pinge against inner surface portions of the drain neck l5, and holding said stopper member within a wider portion of said neck spacedly of the inner wall so that liquid may drain from the sink through the neck l5 and into the container H by passing around and over the exterior and periphery of said stopper member. When closure of the drain is desired to allow water to accumulate within the sink, the stopper arms 24 are retracted as in Fig. 4. Then the stopper member seats further downwardly in said drain neck and tightly closes the same. If larger refuse material is to be introduced into the container ll,
- tion 34.
the stopper 23 may be bodily removed from the drain neck to entirely expose the same.
Positions of adjustment of the stopper arms 24 are retained by a spring washer 3| which is mounted about the operating shaft 25 between the disc 26 and a hub 32 on the inner top portion of the stopper member. It should be noted that the discharge end of the drain neck, while within the upper portion of the container I1 is below the top of the container and in effect provides an annular baffle to prevent fluid and material from being splashed upwardly and out of the drain neck during milling operations and when said container 'is substantially filled with liquid and material.
From Fig. 2, it will be observedthat the lower portion of the container I! is slightly outwardly flared with spaced lateral ears 33 at its lower extremity. Said ears permit attachment of a lower casing section 34 which has registering upper cars 35, there beinga gasket or washer 36 be tween said flanges 33 and 35 and the flanges being secured together by bolts 31. The mode of assembly of the composite casing or container I1, 34 permits the securement within the lower portion of the container of a hardened metal cutting or comminuting shell 38. This shell is fitted into an annular interior recess 39 in the container l1 and seats in a groove 40 in the sec- The lower portion of said shell is of cylindrical form while the upper portion thereof is slightly upwardly, inwardly reduced.
With special reference to the comminuting shell 38 which is shown in detail in Fig. 8, attention is-directed to the fact that the inner face of thelower cylindrical surface thereof is provided with two series of cutting groove The grooves of one series, designated 4|, extend spirally downwardly from a vertical line on one side of the shell to a position one hundred and eighty degrees removed, while the other series of grooves, designated 42, extend from the same starting point as the grooves 4| but in the opposite direction. The terminal of both series of grooves is at the triangular cutting shoulder or boss 43 which extends the full height of said shell 38. Fig. 9 is a schematic inner face view ofthe shell 38 developed longitudinally to show the development of the series of grooves 4| and 42 and their relation to the boss 43.
Integral with the lower portion of the casing section 34 and extending laterally outwardly thereof is a tubular drain elbow 44. The outer end of this elbow may connect with a conventional trap (not shown). The lower portion of the casing section 34 is closed and provides a top bell enclosure for a depended electric motor 45 confined within a motor casing 45 which is complementary to the casing 34 and which is removably secured thereto by elongated bolts 41. The electric motor is of a reversible type, as will be brought out hereinafter. The entire casing or container assembly comprising the members H, 34 and 45 is extremely compact and is susceptible of ready and convenient assembly and disassembly. The compact arrangement is highly desirable in an apparatus of this character as available space below a sink is often quite limited.
The motor shaft 48 extends vertically upwardly through the bottom of the container section 34 and into the interior thereof. The bottom of said section 34 is formed with an enlarged up'wardly projecting bored boss 49 and within the bore thereof and surrounding the enclosed portion of the motor shaft is a bushing 50. The uppermost extremity of the motor shaft 43, above the boss 49, is squared as at 5|. A comminuting rotor 52, generally in the form of a disc, is mounted fast on said squared portion 5| of the motor shaft. Said comminuting rotor is shown in detail in Fig. 5 and is formed of hardened steel. Its top surface is formed with a plurality of equally spaced apart radial ribs 53 and the sector-like areas between the ribs are inclined downwardly outwardlv from the apex. Depending from the bottom of the rotor 52 is an angularly shaped fin 54 which is adapted to turn as a paddle within the'lower portion of the container section 34 radially outwardly of the upstanding boss 49. The rotor 52 is mounted fast on the end portion 5| of the motor shaft by means of a squared opening 55 extending through the center portion of the rotor and of a size to snugly receive the said end por tion of the motor shaft. Said opening 55 is. however, extended through the rotor at an angle to the vertical axis thereof so that in the operative disposition oi the rotor on the motor shaft. the rotor is maintained at an oblique angle. The rotor is furthermore positioned relative to the interior of the container section 'II so that it substantially coincides with the comminuting grooves 4| and 42 within the shell 38, as most clearly shown in Fig. 1. When the rotor is revolved, its periphery produces a'wobbling effect relative to the comminuting surface of the shell 38. The rotor is of a diameter slightly less than the interior diameter of the cylindrical portion of the shell 38 so that slight clearance is" provided between the periphery of the rotor and the ad Jacent inner surface of the shell, whereby material, after being acted on, may pass between the upper end of the boss 4! and the bushing ll.
and has a thrust effect on these parts and thereby acts as a water seal, preventing the flow of liquid from the lower reservoir portion of the container section 34 into the motor casing. The
nnllrotating withinsaldreservolrportion of.
the casing, serves to direct fluid and material from said reservoir portion into the outlet or discharge elbow N. a
As before mentioned, the electric motor ll is of a type which may be reversed or rotated in either direction. For the purpose of operating and controlling the motor, a switch box I] is provided which switch box is depended from the upper portion of the container II. The moimting means for the switch box consists of an arc-shaped band or strap l engaging-an upper peripheral portion .of the casing section 11 and being arcuately and adiustably-secured thereto by means of bolts ll extended through elongated slots 59 in said strap or band 51.
Current-from a suitable source of supll ll (not shown) is led into the switch box through a cable 80. Within the switch box there are movable multi-contact make andbreak elements controlled by an operating knob II and said knob may be turned from an "off" position to' one 'fon position which will cause operation of the motor in one direction, or to another "on" position which will cause operation of. the motor in a reverse direction. Another cable .62 leads from the switch box and extends to the motor 45.
As before suggested, the improved garbage disposal apparatus is adapted to bemounted in connection with and below the normal drain outlet of a sink. when the sink is used for normal purposes and contains only water. and
only water and fine refuse is to be flushed therefrom, it is unnecessary to set the motor 48 into operation. The drain openlng of the sink can in this event be closed to enable the sink to temporarily retain water by manipulation of the stopper arms 24, as heretofore explained, permitting the stopper 23 to tightly seat within the drain neck ill. When the contents of the sink are to be drained. a simple manipulation of the knob 30 of the stopper, p ojects the arms 24 and raisesthe stopper, permitting liquid drainage around the periphery of the stopper and into the container ii. The liquid ultimately I passes around the periphery of the rotor 52 and thence outwardly to the trap and sewer via the elbow 44. When garbage is to be disposed of, the entire stopper member 23 may be. removed from the drain'neck l and this material is then introduced directly into the container II. It is also desirable to flush said material with water from the sink tap. Thereupon, the electric motor 45 is set into rotation by manipulation of the switch, and rotation of the motor in either direction will be eflective for accomplishing the desired purposes. Primarily, the material is milled and churned within the container l1 and is thrown forcibly against'the walls thereof. and as before mentioned, the depending neck It serves as an annular baille or splash plate. Ultimately, the harder solid material gravitates onto the top surface of the comminuting rotor 52. The ribs on said rotor are effective to initially start the contents of the container into rotation and the actionissuch astodrive thematerlal centrifugaliy outwardly against the wall of the shell 88. The wobble action of the rotor I! in turning, in conjunction with the cutting grooves it and 42 and the boss 43, accomplishu grinding, comminuting, and disintegration of v the solids to an extent where said material with the liquid may ultimately pass, in finely ground state, be tween the periphery of the rotor and the inner surface of the shell into the lower reservoir portion of-the container section 34, from whence it is pushed outwardly into the elbow M by the an I. Y
From time to time, it is desirable to operate the motor II in reverse directions, and this serves to clean and free the comminuting teeth and surfaces of material clinging thereto, and it also has a certain sharpening effect in relation to the efm fective edges of said members.
The specific formation of the stopper member 23 in the present apparatus is particularly advantageous. This stopper member may be elevated in the drain neck for fluid drainage purposes. and as the drainagetakes place around the periphery of said stopper member, the stopper member may be formed imperforate and hence there are no apertures therein to clog and to require cleaning.
From theforegoing description it will appear that the improved garbage disposal apparatus is of simple and novel construction, operates efficiently and expeditiously, is compact, and may be readily mounted below a standard sink, and is well adapted for the purposes described.
