This invention relates in generahto grinding machines and more particularly to certain new and useful improvements ingarbagegrindersl.
.It is the primary object of the presentinvention to provide av garbage grinder having an extremely large: capacity, and being capable of. .dis-
integrating all types of garbage ranging from vegetable leaves to heavy roast bones, and is .so constructed that none or the entrant material can be hurled upwardly and out of the grinder throughthe intake opening. thereof.v
.It is a further object of the present invention to provide a garbage grinder having means for flushing the incoming garbage downwardly into the grinder cage to. prevent clogging or choking .of' the intake.
Withthe aboveand other objects in'view', my
invention resides in the novel features oi (form, construction, arrangement, and comhinatiori of parts presently described pointed out the claims.
1 v In theaccompanying drawing:
Figure 1 is a front view of a garbage" grinder constructed in accordance with and embodying the present invention: I Figures 2 and 3 are transverse sectional views taken along lines 2'-2 and 3-3; respectively; of
Figure I; and Figure 4 is a transverse sectional'vi'ew taken along line 4-4- of Figure 3 Y 7 Referring now in more d'etaii and by reference characters to the accompanying drawing, which illustrates the preferred embodiment oi the present invention, designates a; garbage grind-er comprising a unitary cast housing f provided at its upper end an upwardly opening intake aperture '2'. a he 'bi'ght portion of the passage 4 is reinforced by a web 6 integrally formed with the housing 1. Provided in the rearward wal oi'the passaget, adjacent-"the throat portion 5, is an internally threaded aperture I for receiving the threaded end of a water pipe '8 connected to a conventional Water source- (not shown). Suitably seemed, as by Welding, to the race of the passage 4, justabove the aperture 1, is a bafll'e plate- 9 extending :downwardly and outwardly beyondthe aperture 1 for deflecting inflowi ng' water over the bottom wall of the passage 4.
its lower end, the passage 4 opens into a cylindrical, horizontally disposed grinder cage Hi, the rearward end of: which is provided with: a removable and plate 11 suitably-securedto the housing f by ho'lts l'z. The bottom portion of the HI communicates with a downwardly extending discharge chute 113,. the sideand' forward portions oi which converge into a discharge ori- .fioe: "M provided. with a peripheral flange 115 for 'seourement. to a sewer or other dischargeline '("not showni...
The end plate H is: provided with a. centrally located aperture 1-6 through which extends a horizontal shaft H of. a conventional electric motor l8; (iregmentazllyindicated) the: latt'enbeing mounted; upon the end plate II. The axis of: rotation of said shaft i1 lies? in the sameperpendicular plane as the: vertical axis of: the intake openingfz'. Mountedzupon: the shaft. 1 1, with.- in' the aperture 16 of the end plate:- I I is a pack.- .ing gland .for preventing. any substantial leakage of water along the shaft W. The projeotingend of the shaft l1 terminates approxi.- mately midway "in the cage lid and, keyed there'- on, a. conical collar 20: abutting at its forward end against a retaining col-1ar21- secured upon the extremity of the-shaft 11.. Ri-gidly mounted upon the conical collarikitsand'projectingradially therefromat 130 degree intervals, are two arms aperture 2,- the margins in which integrally provided with a peripheral: flange 3 for 'conventiona-lsecurem'ent to a pipe; sink, waste hopper 'or the like (the latter not being shown)...
5 The: intake aperture 2 opens downwardly "into a curved, downwardly extending passage 4;. havmg'arelatively short vertical portion! and:
ingI-outward-ly therefrom, and thence rearwardly,
in substantially til-shaped 'tormationj, whereby the. central portion at the passage '4", as at 4-';,- wild 22, of increasing width: and being provided on their-outer ends with". cutter blades 23;, which are releasably held: in place by bolts 24., provided in their lead'ing'aedgewith" a pluralityof spaced receases-or nicks 25. Removably disposed by bolts 26, in the walls of the chamber Hi at either side thereof'in. diametrally opposed position, are stacutter bars 21 having. in their inward-1y presentediaces a,,plurality'of. recesses 28 which beletera-ly disposed. fromsthe vertical otthe a during operation.
Rress fitted against the-upper wall: portion of 3 the cage I is a semi-cylindrical filler plate 29, for reducing to a desired minimum the clearance between the cutter blades 23 and the wall of the cage H] for effective grinding action thereof. Provided in the lower half portion of the grinding chamber [0 is a semi-cylindrical, foraminous grinder screen 30 abutting at its upper margins against the under face of the cutter bars 21 and disposed in its bottom portion across the upper and of the discharge chute I3, said screen 30 being supported upon a shoulder 3i integrally formed in the walls of the cage 10.
In operation, the motor [8 is actuated to, effect rotation of the rotors 22 and the water source is turned on to provide a flow through the pipe 8 and into the passage 4. The incoming water is deflected by the baflie s downwardly against the upwardly presented, curved face of the web 6,
from whence it will be deflected against the face of the outwardly curvedportion oi the passage 4 and will thereon flow downwardly along the face thereof, into the cage It. It will thus be seen that the baiiie Q and the curvature of the passage 4 prevent any water from being deflected upwardly into the intake aperture 2 and assure that such water will properly flush any surfaces to which garbage might normally adhere. Garbage is then dumped into the passage 4 through the intake, aperture 2, and is sluiced downwardly along the curved passage 4 by the flushing water and carried thereby into the grinding chamber I0, wherein the garbage is pulverized by the cutter blades 23. The ground garbage will drop through the apertures in the screen 30 downwardly along the discharge chute l3 and outwardly through the orifice M for discharge into the sewer or into any suitable receptacle. During the grinding operation, relatively large garbage elements will be prevented from being carried completely around the grinding cage H] by the cutter bars 2'! and, thus, the garbage will be substantially maintained in either the upper or lower portion of the cage I0 until sufliciently pulverized for passage through the screen 30.
It will be noted that in the event garbage tends to accumulate faster at the entrance of the cage Hi than can be adequately accommodated therein, any back-wash occurring therefrom will be di rected against the inner face of the forwardly curved portion of the passage 4, thus preventing any upward gushing through the intake aperture 2 into the face of the operator. This outstanding result is achieved by the combined effect of the horizontal disposition of the shaft I! and the sinuous character of the passage 4. As stated above, there is no possibility of incoming garbage accumulating upon the walls of the passage 4 since the path traveled by the sluicing water assures that the more remote surfaces of the passage 4 will be continuously flushed.
It will also be obvious that the curvature of the passage 4 makes the cage in relatively inaccessible, so that an operator could not in any untoward manner get his hands caught in the rotating arms 22 should an attempt be made to disrupt manually any material piled up at the opening to the said cage 10.
It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the garbage grinding machine may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
Having thus described my invention what I 'with a substantially semi-circular passageway,
the center line of which lies substantially within 'a vertical plane passing through the center line of the Igrinder'cage, and grinding means disposed in said chamber.
2; A garbage grinder comprising a housing ,having a cylindrical grinder cage with a horizontally presented coaxial intake opening, a sinuous intake member having a vertically upwardly presented intake opening and a horizontally presented discharge opening coincident with the intake opening'of the grinder cage, said member, between its openings, being provided with a substantially semi-circular passageway, the center line of which lies substantially within a vertical plane passing th'rough the center line of the grinder cage, and water inlet means provided in said passage.
3. garbage grinder comprising a housing having an upwardly presented intake aperture, saidhousing being further provided with a downwardly extending substantially semi-circular passage, water inlet means provided in said passage, a deflector member mounted in said passage spacedly from the water inlet means for directing water downwardly along the wall of said passageia substantially cylindrical grinder cage having a coaxial intake opening directly communicating with the lower end of said passage, and rotary grinding means disposed in said chamber the center line of the passage and the center line of grinder means being disposed in substantially the same plane,
