Definitions
- the present invention relates to apparatus for the disposal of waste material, and particularly to apparatus for receiving a mixture of garbage and water and reducing or comminuting the solid particles to produce a flowable mixture suitable for discharge to a sewer system.
- the object of my invention is to provide an improved construction in apparatus of this type, and for a consideration of what I believe to be novel and my invention, attention is directed to the following description and the claims appended thereto.
- Fig. 1 is a sectional elevation of a waste disposal device embodying my invention
- Fig. 2 is a sectional view, taken on line 2--2 of Fig. 1
- Fig. 3 is an enlarged fragmentary view showing the relation of one of the impeller elements to the shredding chamber
- Fig. 4 is a development of part of the side walls of the shredding chamber
- Fig. 5 is a bottom plan view of that part of the shredding chamber shown in Fig. 4.
- a waste disposal device having an upper casing section I fixed to and depending from the drain opening 2 of a sink 3.
- a frusto conical casing section 4 Fixed to the lower end of the casing section I is a frusto conical casing section 4 having a bottom flange 5 carrying an electric motor 6 and provided with an outlet 1 for connection with the drain pipe of a sewer system.
- a frusto conical shredding chamber 8 Within the lower casing section 4 is a frusto conical shredding chamber 8 clamped between a shoulder 9 at the upper end of the casing section B and a shoulder ill on the bottom flange 5.
- the shredding chamber is resiliently supported by rubber rings I l and I2 respectively arranged between the upper and lower ends of the shredding chamber and the shoulders 9 and Ill.
- the rubber rings serve as sound isolating supports for the shredding chamber and also as seals between the ends of the shredding chamber and the casing.
- the shredding chamber is a replaceable unit which may be disassembled from the casing by removing the bottom flange.
- recesses I6 receiving impeller or crushing elements I! pivotally carried on pins [8 extending across the side walls of the recesses 16.
- the center of gravity of the impeller elements H is. above and radially inward ofthe pivot pins 18. Accordingly when the flywheel I3 is stationary, the impeller elements pivot inward to the position shown at the right in Fig. 1 in which the surface IS on the impeller elements rest on the inclined surface 20 at the inner edge of the recesses l6.
- the impeller elements pivot outward to the position shown in Fig. 3 and are held in this position by centrifugal force.
- the impeller elements are free to pivot inward to prevent jamming.
- In the side walls of the shredding chambe at the lower end are a series of straining grooves 2
- limit the size of particles discharged from the shredding chamber into the receiving chamber.
- the straining grooves alone, while satisfactory for brittle materials such a bones, are not entirely satisfactory for leafy material such as corn husks. It would be possible for such material to pass lengthwise through the grooves in a stringy form which might ultimately result in clogging of the drainpipes of the sewer system.
- The shearing surfaces 23 are inclined downwardly and outwardly, as shown in Fig. 3, and have a running clearance with corresponding tapered surfaces 24 at the discharge ends of the straining grooves.
- the shearing surfaces 23 Upon rotation of the flywheel l3 the shearing surfaces 23 are moved past the discharge ends of the straining'grooves and act to clip material flowing through the grooves. This clipping action is particularly effective on the stringy leafy materials and reduces the size of such materials so as to prevent clogging of the drain.
- fiuid propelling projections 25 which act as a centrifugal pump to force the fiowable mixture of comminuted garbage and water from the receiving chamber 22 to the outlet 'I. This centrifugal pumping action is increased by vanes 26 in the receiving chamber fixed to the under side of the flywheel;
- the shredding chamber 8 is preferably made of an alloy iron casting heat-treated to a cutting tool hardness.
- shredding projections consisting of bosses 21 having cutting surfaces 28 extending radially inward from and circumferentially around the side walls of the shredding chamber.
- the leading ends 29 of the cutting sur faces are smooth, and the remaining part of the cutting surfaces is provided with scallops 30.
- the cutting surfaces are presented toward the larger diameter end of the shredding chamber and are inclined toward the impeller element I! as regards its direction ofrotation so that the material contacting the cutting surface is deflected toward the impeller elements.
- the cutting surfaces project radially inward from the walls of the shredding chamber a distance which is relatively small compared to the length or circumferential extent of the cutting surfaces.
- the bosses 21 have relatively smooth surfaces 3
- the tapered surfaces 32 tend to deflect material toward the impeller elements.
- and 32 impose a minimum of resistance
- the bosses 21 are arranged in circumferentially spaced rows distributed about the axis of the chamber, each row consisting of two bosses one above the other.
- the bosses are so arranged that the cutting surfaces of the bosses in adjacent rows are, as shown in Figs. 1 and 4, staggered along helical curves on the side walls of the shredding chamber.
- the helical curve produces an additional force feeding the whirling mass of material toward the impeller elements.
- the staggering of the cutting surfaces along the helical curve improves the cutting action on larger pieces of material in that successive cutting surfaces act upon different portions of the material. This result is also obtained by the circumferential spacing of the cutting surfaces since the spaces between the cutting surfaces permit the material to change its position in the whirling mass. In other words, the material tends to follow the cutting surfaces while in contact therewith and, in
- the cutting surfaces are staggered axially or vertically along the side walls of the shredding chamber in that in each of the vertical rows the inner edge of the lower cutting surface is radially outward of the outer edge of the upper cutting surface.
- the lowermost bosses 21 terminate adjacent the lower end of the shredding chamber, as shown in Figs. 1 and 2, providing shearing surfaces 33 for cooperation with the impeller elements ll. In the present construction three equally spaced bosses are provided cooperating with the impeller elements.
- the garbage is put into the upper casing section I through the drain opening of the sink, the water is turned on and the motor started, the rotation of the impeller elements I! causes the mixture of garbage and water to be whirled about the side walls of the shredding chamber 8.
- the solid particles are iii thrown outward by centrifugal force against the shredding chamber and are shredded or reduced in size by impact with the upper cutting surfaces 28 and by a shearing action between the lowermost bosses 21 and the impeller elements 11.
- the shredded material falls through the straining grooves 2
- the material is subjected to a shearing or clipping action by the surfaces 23 on the impeller elements. This latter action is effective in cutting stringy material into short pieces so as to prevent clogging of the drains.
