A motor, preferably an electric Fig. 4 is a detail plan view of a switch and motor shown conventionally at 16, is disvalve controlling device, and posed adjacent the casing and has its shaft Fig. 5 is a detail enlarged section showing 17 alincd with the shaft 14 so that it may be 70 the joint between the casing and the hopper. coupled thereto, a flexible coupling being iii- It is the purpose of the present invention (heated conventionally at 18, to connect the to provide a mechanism which may be distwo shafts so that when the motor is enerposed adjacent to or set in the usual sink or gizcd the grinding rotor 5 will be rotated 5 otherwise conveniently located and connected within the casing. The casing is provided 75 directly to the sewer or drainage outlet of with feet 19 of any convenient form through the building. To that end, we provide a cas- ,which fastening devices may be inserted into ing 1 which is substantially cylindrical in its a convenient llX0(l support and the motor main portion and is provided with a depends likew se rigidly secured in place by fasten- 8 ing outlet nozzle 2 whicli is tapered toward mg devices inserted through feet 20. A its lower end and at its lowerend is conswitch 21 is provided to control the motor nected to the usual drain pipe or sewer outlet and has one side connected to the lead-in wires 3.

At one side near its lower end the switch leverwill be, of course, rocked in 109 the opposite direction to open the switch and stop the motor.

Secured upon or formed upon the inner wall of the casing l are series of ribs or breaker teeth 27, said teeth being arranged in series extending longitudinally of the easing with the teeth-in each series spaced apart 7 and the teeth are preferably triangular in form with one side extending abruptly from the wall of the casing to cooperate with similar teeth 28 which are formed upon the grinding rotor 5, as shown in Figs. 2 and, 3. The teeth 28 are so located as to alternate with the teeth 27 whereby in the rotation of the grinder a tooth 28 will pass between two adjacent teeth 27 and matter caught between the teeth will be pulverized and reduced to a fine pulpy' condition. The teeth upon the rotor are arranged spirally, as shown clearly in Fig. 3, so that the engagement of said teeth with the stationary teeth 27 will be a gradual and successive action extending from one side of a series of stationary teeth to the opposite side of the same and the garbage or other matter acted upon will, consequently, be so engaged that it cannot clog the action of the machine but will be rolled from one side to the opposite side of the easing and successively acted upon by the several teeth upon the rotor. If. a bone, for instance, should be caught between opposed teeth, it will not be held in the caught position so as to break the teeth or otherwise damage the machine or clog the action but will be partly cracked and partly turned aside and eventually will be thoroughly pulverized so that it may pass through the sewer without clogging the same. It will be noted that the interior walls of the main hopper are substantially parallel to each other while the outlet end or throat of the main hopper where it merges into the walls of the cylindrical casing is of substantially the same width as the diameter of the grinding rotor so as to afiord ample clearance and prevent clogging or obstruction of the garbage as it is delivered directly onto the grinding rotor. The width of the outlet or throat of the main hopper not only permits the garbage or other refuse to be fed freely and in large quantities directly onto the grinding rotor but owing to the inclination of the overhanging rear wall of said hopper, any refuse thrown off by the centrifugal action of the rotor will strike the inclined rear wall of the hopper and be deflected downwardly directly onto the rotor to be again acted upon by the teeth of the rotor. V

The grinder rotates in the direction indicated by the arrow in Fig. 2 and any water which might be thrown directly upward by centrifugal action will be directed toward the upper rear wall of the main hopper 4 and will thereby be deflected back into. the casing to pass out of the same instead of being thrown out through the top of the casing to spread over adjacent objects or upon the operator or other persons who may be near the apparatus. The groove 6 in the upper edge of the hopper 4 receives the lower edge of the chute or auxiliary hopper and permits the chute to seat deeply in the main hopper so that any water which may find its way up into the chute or extension cannot overflow but will find its way back to the casing. The material to be acted upon is placed in the chute 7 and gravitates into the casing and will rest upon the rotating grinder. The rotation of the grinder will carry the teeth thereon through the matter and will thereby feed it around to and against the stationary teeth on the casing and a macerating action will occur as the teeth are successively engaged. The pulverized garbage will be. fed around by the action of the teeth until it reaches the outlet 2, whereupon it will descend through said outlet into the drainage pipe as is obvious. WVater admitted through the pipe 10 into the casing will flush the same and cause the macerated matter to pass easily into the drain pipe and be carried through the same as the water escapes. It will be noted that the pipe 10 discharges into the casing at the top of the tapered outlet nozzle 2 and immediately under the crushing rotor, so that the full force of the stream of water is exerted directly uponthe body of pulverized matter to drive it into the sewer. It will also be noted that some of the breaker teeth 27 are located immediately adjacent the outlet and the crushed matter will drop at once into the nozzle instead of being carried through va tortuous path or through a series of passages which would provide many opportunities for clogging the machine. When all the matter on hand has been disposed of, the chute or auxiliary hopper 7 may be removed so that it will notbe in the way of persons desiring to make other use of the room, and any. convenient cover may then be placed over the open end of the main hopper 4 so as to prevent any matter being dropped thereinto and also prevent children or other persons carelessly placing their hands within the hopper where they would be liable to be injured through accidental rotation of the grinder. v The apparatus is exceedingly simple and compact and it may be installed at a low cost and in use will effectually dispose of garbage and other waste matters.

Having thus described the invention, we claim:

1. A11 apparatus for disposing of garbage and similar refuse comprising a horizontally disposed casing having a depending dis-' charge nozzle for connection with a sewer and provided at its upper portion with an integral tubular extension projecting up wardly and laterally therefrom and constituting a hopper the interior walls of hich are arranged at an angle to the vertical axis 'of the casmgand 'sposed substantiall ar- I allel with each oter, a. cylindrical grin g rotor 'mounted for rotatlon within the easing, the throat of the hopperat'its junction with the walls of the casing being of substantially the same width as the diameter of the rotor whereby refuse thrown outwardly by the centrifugal action of the rotor will impinge against the adjacent wall of the hopper and be deflected thereby onto said rotor, and a water inlet communicating with the .interior of the discharge nozzle for flushing ,said discharge nozzle.
