This hopper is of an elongated 2 2 disposed upon one end portion and provided inverted bell form, as shown most clearly in'Fig. 75

In one side as shown in the drawings, this branch hopper 0f e casing 4 is fitted a lock 1 h v or conduit being provided with a circular upper t n ry blades 12 formed on its inner sid and end intended to register with an opening 27 in 95 the inner surface of this block is concave and disa t bl 23 hi h i arranged immediately posed concentric with the rotating grinder shaft jacent; th hopper d i provided with a t 13 which extends axially through the casing and ing flange around it ntir d as h h carries a grinding or breaking block or cylinder garbage i to be dumped upon this table and 14 p which a a d s ri s f r a or the attendant will be provided with some suitcutter blades 15 which are arranged in spiral rem m t whereby t may be spread and lation so that, as the cutter or breaker rotates, pushed int and through the opening 27 and any the blades 15 will successively cooperate with the tableware or tt which should t pass to stationary blad s 1 to pulverize a break up the sewer or the macerating elements, which may garbage. The Shaf 13 extends through journal have been gathered with the garbage, may be 5 boxeslfi provided therefor upon the ends of the detected and reclaimed. Preferably, the table casing and is coupled to the driving shaft of a will be connected with the branch hopper 26 at motor 17 which is supported upon the base 1 withone end by a hinge 29 and will be supported by in the housing 2 and may be of any approved form, a prop 30 at its opposite end whereby it may be being illustrated conventionally. Preferably, a swung upwardly when not in use and thereby facilitate cleaning of the hopper and be out of the way.

A hollow rim or annular chamber 31 is formed around the upper end of the branch hopper 26 and in the bottom of this annular chamber are perforations 32 which are located immediately adjacent the inner surface of the wall of the branch hopper so that water fed into the annular chamber may flow down through the hopper and wash the garbage into and through the apparatus and the sewer. The water is admitted to the annular chamber through a supply pipe 33 connected with the house water system and having a branch 34 leading directly into the annular chamber. A second branch 35 extends downwardly alongside the branch hopper and has its terminal secured in and passing through the block 11 so as to discharge in the lower portion of the casing 4. It will be noted upon reference to Fig. 2 that the terminal of the branch pipe 35 is disposed approximately tangential to the grinding roll 14 and consequently the stream issuing therefrom will pass to the outlet nozzle 5 and play directly upon the pulverized matter which has been fed thereto by the grinding or breaking roller. The branches 34 and 35 are connected with the supply pipe 33 through a T- coupling 36 and in the supply pipe, in advance of said coupling, is a valve 37 which may be of any well known type and is illustrated in a conventional manner only. Preferablygthe valve will be a gate which is pivoted at one side of the valve casing and is adapted to move across the bore of the supply pipe. The pivot of the valve is extended through one side of the valve casing and has a lever 38 secured thereon, said lever having a fork 39 at its outer end which receives aswitch handle 40 controlling a switch mounted within a switch casing 41 which is carrled by a bracket 42 secured upon the water pipe. It will thus be seen that when the lever 38 is rocked to open or close the valve 37, one side of the fork 39 will impinge against and actuate the switch handle 40 so that the switch will be shifted to close or break the circuit controlling the motor 17. The motor will thus be permitted to run only when garbage is being treated and water is flowing into the hopper. It is to be understood, of course, that the machine need not be driven by a motor but may be actuated by hand and for this purpose, the shaft 13 is provided at one end with a tenon 43 adapted to be engaged by any convenient turning tool.

The wall of the hopper 22, immediately above the inlet opening 25 and at its junction with the branch 26, is' flared outwardly, as shown at 44, and at the lower end of the inlet opening 25 is formed an inwardly projecting lip 45.

In use, the garbage is fed through the opening 2'? to the branch hopper 26 and will pass through the narrow vertically elongated inlet opening 25 into the hopper 22 wherein it will fall onto the grinding or pulverizing roller 14. This roller is rotated so that the abrupt ends of the blades 15 will be opposed to the abrupt ends of the blades 12 in action and, consequently, garbage which may be engaged between the blades will be very effectually broken up and reduced to a pulpy condition, the flow of water accelerating the reducing of the garbage and also aiding in feeding the same through the apparatus. The blades 15 will just clear the breaker guard or lip 19 and, consequently, there will be no jamming of the parts due to any matter being caught between the breaker and the blades, but any such matter, such as bones, will be caused to roll toward one end of the casing due to the spiral arrangement of the blades 15 and the consequent successive presentation of the same to the breaker. As a result of this action, bones and similar articles will be gradually chipped or broken without dam aging any of the working parts of the machine. The roller 14 rotates at some speed and light matter, such as shreds of lettuce or small vegetables, tends to rise or flow back from the grinder within the hopper. Experience has demonstrated that these lighter elements tend to work back to and out of the mouth of the hopper, but, in the present apparatus, this objection is overcome by the provision of the deflecting lip 45 and the flared surface 44 and by the design of the hopper. The lighter particles which may be thrown upward by the action of the grinder or breaking roll will be deflected from the inlet opening 25 by the lip 45 and if such elements should be thrown u'pto the top of the hopper, the flared wall 44 will deflect them over the inlet opening so that they will be returned immediately to the pulverizing chamber, it being noted that the lower edge of the flared wall 44 and the upper end of the inlet opening 25 are somewhat below the top of the hopper and the branch hopper is flared above the lower edge of the wall 44 so that there is a restricted passage in the plane of the lower edge of said wall and, consequently, the objectionable backflow will be effectually arrested. The hopper is of such shape that the garbage and flushing water will be retained therein while being ground or macerated, notwithstanding that the bore of the rim 31 remains open. While the material may be thrown around and up against the top of the hopper by the rapidly moving rotor, it will always fall back onto the rotor and will eventually pass through the device and into the sewer. After all the garbage has passed, the flow of water and the movement of the rotor are continued for a short period during which the hopper will be washed by the clear water being thrown against its inner surface.

From the foregoing description, taken in con- 'nection with the accompanying drawings, it will be seen-that we have provided an exceedingly simple and compact apparatus by the use of which garbage will be veryeffectually pulverized and reduced to such form that it may be readily carried off through the house sewer connections. The block 11 carrying the stationary blades 12 is removable and it is therefore possible to replace broken or worn out blades 12 without requiring the provision of an entirely new casing. The removability of the block 11 also facilitates inspection and cleaning of the lower casing.

Having thus described the invention, we claim:

Apparatus for the purpose set forth comprising a casing, a pulverizing roll within the casing, stationary blades on the wall of the casing cooperating with the pulverizing roll. a hopper rising from the casing and having an inlet opening in one side, a branch hopper rising from the side of the hopper around the inlet opening, a table hingedly connected to the upper end of the branch hopper and having an opening therethrough registering with the branch hopper, and means for supplying running water to the branch hopper and to the casing.
