corporation of Michigan .application August 2, 1946, Serial No. 687,835
(Cl. Zai-257 l 2 Claims.
This invention relates to garbage disposal apparatus and has particular reference to certain new and useful improvements therein whereby the reducing of the food to be disposed of is more efficiently accomplished.
v The construction herein disclosed and claimed is an improvement upon that disclosed in the application of Kemper M, Hammell, Serial No. 524,836, filed March l, 1944, for Garbage Disposal Apparatus. and to which application ref-- erence may be had for a more complete disclosure of a garbage grinder adapted for domestic use and the controls therefor. The invention herein disclosed and claimed has particular reference to the construction and arrangement of the reducing means whereby a more efficient reduction of the garbage to be disposed of is effected.
Principal objects of the invention, therefore. are to provide:
A new and improved garbage disposal apparatus;
A garbage disposal apparatus embodying new and more efiicient reducing means;
A garbage disposal apparatus wherein the reducing means are constructed and arranged so that centrifugal force is utilized to hold water and food particles in the shredding ring zone near the bottom of the chamber and the outlet therefrom whereby a gain in speed of operation and discharge pressure is obtained.
Other and further objects of the invention will be apparent from the following description and claims and will be understood by reference to the accompanying drawing, of which there is one sheet, which, by way of illustration, Shows a preferred embodiment and the principles thereof and what I now consider to be the best mode in which I have contemplated applying thoseprinciples. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.
In the drawings:
Fig. 1 is a fragmentary vertical sectional view of an apparatus embodying the invention; and
Fig. 2 is a sectional view taken along the line 2-2 of Fig. l, with parts thereof broken away.
The apparatus in general comprises an upright chamber I@ adapted for receiving garbage to be reduced, a frusto conical shredder ring I2 extending upwardly from the periphery of the bottom wall I4 of the chamber and defining the side wall of the chamber at the bottom thereof,
lli
2 the larger end of the shredding ring being arranged at the bottom of the chamber. The chamber may be connected to the drain outlet of the sink for receiving garbage and water therefrom.
The ring I2 is provided with a series of axially extending cutting teeth It and with a series of axially and circumferentially extending radial openings IS, the openings I8 being arranged alternately with respect to the teeth I5. As a matter of fact, one Side of each of the openings I8 is dened by a part of a cutting edge It. Such openings I2 form a radial discharge outlet for reduced material. The largest dimension of each 2 of the openings i8 is a controlling factor in the size to which the material must be reduced before it is discharged through the openings I8. An annular trough 2i) surrounds the lower end of the chamber l@ and is in communication with the openings i8 so as to receive material discharged therethrough and to conduct such material to a spout leading to a sewage or drainage system.
Power driven rotary means are arranged in the bottom of the chamber lil for impelling material therein against the teeth l5 and through the openings I8, such power driven rotary means comprising a rotary hub 22 and a plurality of radially extending hammers 24. Each hammer is pivotally connected at 26 to an arm 28 of the hub and is adapted to swing in a plane normal to the axis of rotation of the hub 22. The hub 22 is connected to a shaft 3) which extends upwardly through the bottom wall of the chamber I. The shaft til may be driven by an electric motor and may comprise an extension of the shaft of such motor. A running Seal 32 is arranged to form a seal between the shaf 3@ and the bottom wall of the chamber It.
The hammers 2d are positioned on or in closely spaced relation with the bottom wall of the chamber and are adapted to sweep material on the bottom wall against the teeth I6 during operation of the power driven rotary means. The speed of operation may be 1'750 R. P. M. The hammers 2li are constructed and arranged so that during operation of the power driven means the outer ends of the hammers will be positioned close to the cutting teeth I6. The outer ends of the hammers are also tapered downwardly and outwardly so as to correspond with the conical section of the shredder ring I2.
In addition, the outer ends of the hammers may be provided with serrations or vertically extending teeth 34 which help to prevent material slipping past the ends of the hammers. The pivotal mounting of the hammers 24 permits them to yield in the event that their path is obstructed. The hammers are of a substantial height and extend upwardly above the openings I8 and may be provided with agitators 3G. The teeth I8 extend from the bottom wall of the chamber I4 to above the top of the hammers while the openings I8 are in the plane of the hammers or impellers 24.
I have found that a taper of six degrees for the shredder ring is satisfactory. The teeth I6 face the leading or forward edges of the impellers 24 as the same are rotated. The teeth are arranged at an angle of the order of eleven degrees relative to the vertical axis of the chamber I0 so that the teeth slope downwardly and in the direction of rotation of the impellers 24. The construction and Aarrangement of the shredder ring teeth I6 and the hammers 24 are such that material in the chamber is forced downwardly into the path of the hammers during the rotation of the power driven means. ln the extended positions of the impellers as illustrated in Fig. 2, the shredder ring teeth I6 overhang the outer ends of the hammers 24.
The bottom wall of the chamber may be provided by a casting which denes a part of the trough 20 and which is provided with an annular seat 40 upon which the shredder ring i2 seats. A shell 42 seated on such casting and secured thereto defines at least part of the chamber if! and is provided with an annular shoulder 44 which bears against the upper edge of the shredder ring l2 for holding the same in the position illustrated.
With. the shredding ring illustrated which tapers downwardly and outwardly, centrifugal force tends to hold water and material to be reduced in the shredding ring zone, that is, in the plane of the hammers, near the bottom of the chamber where such material may be impelled by the hammers against the cutting teeth and also through the openings i8. With this arrangement eiiicient reduction of the material to be reduced is obtained, and in addition the discharge pressure of the reduced material is increased which helps to force the material through the trough 20 into the drainage system. Of course it is understood that water should be supplied to the chamber i during the operation of the reducing means so as to aid in carrying the reduced material through the openings I8 and through the trough 20.
While I have illustrated and described apreferred embodiment of my invention, it is understood that this is capable of modification and I therefore do not wish to be limited to the precise details set forth but desire to avail myself of such changes and alterations as fall within the purview of the following claims.
