Filed Apr. 25, 1962, Ser. No. 190,179 9 Claims. (Cl. 14195) This invention relates to a new and improved garbage and trash disposal device for installation in the wall of a building, such as a house, so as to extend therethrough to provide for the disposal of refuse material from the interior of the building into a container positioned on the exterior side of the building wall.

Garbage and trash disposal devices of this general type have been proposed heretofore. Such devices provide satisfactory service in instances where a person attending to the disposal of garbage and trash is careful to observe when the container located outside of the building has been substantially filled with refuse material and does not attempt to dispose of additional refuse material by using the device until the container has been emptied. Failure to observe that the container has been substantially filled with refuse material may cause overloading of the container with the result that the excessive refuse material either spills outwardly of the container about the surface on which it stands or backs up in the discharge end of the garbage and trash delivery chute communicating with the container. In the latter case, an attempted removal of the container to empty the refuse material therein is likely to cause the person so engaged in emptying the container to be subjected to the flow or" the excessive refuse material backed up in the discharge end of the garbage and trash delivery chute. Such an occurrence would be extremely distasteful to the person involved. Overloading of the container of garbage and trash disposal device of the type described in either instance would contribute to a generally unsanitary condition of the premises about the refusereceiving container.

It is therefore a primary object of this invention to provide an improved garbage and trash disposal device of the type described which includes a control mechanism associated with a refuse-receiving container disposed on the exterior side of the building wall with the control mechanism being responsive to the filling of the container with refuse material to a predetermined level for actuating an indicator means to inform an attendant that the container should be emptied of refuse material.

It is another object of this invention to provide an improved garbage and trash disposal device of the type described having an operable closure for the inlet end of a chute means through which refuse material is dispensed from the interior of the building into a container positioned on the exterior side of the building wall with a latching mechanism actuatable in response to the filling of the container with refuse material to a predetermined level to lock the closure in covering relation to the inlet end of the chute means for preventing further disposal of refuse material through the chute means until the container is emptied, thereby avoiding an unsanitary overloaded condition of the container.

3,17 1,44 7 Patented Mar. 2, 1965 It is another more specific object of this invention to provide an improved garbage and trash disposal device of the type utilizing a chute means for dispensing refuse material from the interior of a building through a building wall and to a location on the exterior side of the building wall, wherein the chute means includes branch chutes respectively leading to first and second refusereceiving containers positioned on the exterior side of the building wall for selectively directing refuse material into either of the containers depending upon the position of a valve member alternately movable between positions closing one or the other of the branch chutes. In the latter respect, once the disposal device has been placed in operation with refuse material being discharged from one branch chute into a first container associated therewith, and with the other branch chute being closed by the valve member, upon the first container attaining a substantially filled condition, the valve member is caused to move to a position closing the branch chute associated with the first container and opening the other branch chute to thereafter permit refuse material to be discharged through the other branch chute into the second container associated therewith.

FIGURE 10 is a vertical sectional view taken substantially along the line 10-10 in FIGURE 9; and

FIGURE ll is a diagrammatic view of the electrical system employed in the modified form of the garbage and trash disposal device illustrated in FIGURES 840, inclusive.

Referring more specifically to the drawings, FIGURE 1 illustrates one embodiment of the invention which is installed through the wall W of a building, such as a house, so that garbage and trash may be dispensed from the interior of the building to a refuse-receiving container located on the exterior side of the building wall W permitting convenient removal of refuse material from the premises. In this connection, the garbage and trash disposal device is preferably installed so as to locate its inlet end in the wall W immediately above a counter-top T in the vicinity of a sink, as in the kitchen of a house.

The garbage and trash disposal device comprises a chute 10 which includes an upper end portion providing an inlet 11 for receiving refuse material dispensed there into and a lower end portion providing an outlet 12 for discharging refuse material from the chute 10. A container 13 for receiving refuse material is positioned on the exterior side of the building wall W below the outlet 12 of the chute 10. It will be observed that the container 13 is provided with a cover 14 having a central opening vertically alined with the outlet 12 of the chute 10. A connecting sleeve 15 extends between the chute l and the container 13, the upper end of the sleeve 15 being frictionally received about the outlet end of the chute and the lower end of the sleeve being slidably received within the central opening formed in the cover 14 for the container 13. The lower end of the connecting sleeve 15 terminates in a laterally outwardly extending retainer flange 16 underlying the cover 14 about the central opening formed therein for supporting the cover 14 in a position vertically alining its central opening with the outlet 12 of the chute 10.

A closure 17 is provided for the inlet 11 of the chute 10, the closure 17 comprising a pair of door members 20, 21 respectively hingedly mounted to opposite side walls of the chute 10 at the inlet end thereof for pivotal movement between positions opening and closing the inlet 11. In this connection, it will be observed in FIGURES 4 and 6 that each of the door members 20, 21 is provided with a spring member 22 associated with the hinge mounting thereof and having a pair of spring arms extending at right angles to each other in juxtaposition with the corresponding side wall of the chute 10 and the interior surface of the respective door member 20 or 21. The door members 20, 21 are normally urged by the spring members 22, 22 to pivot outwardly with respect to the chute 10 for assuming positions in flush relationship with each other to close the inlet 11 of the chute 10, as shown in FIGURE 3. In the latter respect, the door members 20, 21 may be set inwardly of the mouth of the inlet 11, and a strip of resilient molding material 23 may be installed along the walls of the chute 10 at the mouth of the inlet 11 so as to overlie the outer marginal edges of the door members 20, 21. Thus, the strip of molding material 23 serves as a restraining means or bumper to limit the outward pivotal movement of the door members 20, 21 under the influence of the spring members 22, 22, wherein the door members 20, 21 will assume a flush relationship with each other in closing the inlet 11 of the chute 10. It will be understood that the door members 20, 21 are adapted to pivot or swing inwardly upon the application of a force against their outer exposed surfaces overcoming the biasing effect of the spring members 22, 22, such as by pushing against the door members 20, 21, to open the inlet 11 of the chute 10 for dispensing refuse material thereinto.

A closure 18 similar in structure and in operation to the closure 17 is provided in the chute 10 adjacent the outlet end thereof for preventing the accumulation of i ll noxious odors from the container 13 having refuse material therein Within the chute 10 to avoid the transmission of such odors backwardly through the chute 10 and into the interior of the building when the inlet 11 of the chute 10 is open during use of the device. The closure 18 opens under the weight of refuse material passing downwardly through the chute 10 to permit the refuse material to be discharged from the outlet 12 of the chute 10 through the sleeve 15 and into the container 13, while returning to a closed position when no refuse material is being dispenscd through the chute 10 to prevent the admission of noxious odors from the container 13 to the portion of the chute 10 above the closure 18.

Referring to FIGURES 3, 4 and 7, it will be observed that a pair of apertured lugs 24 are provided on the door members 29, 21 along the upper end portions thereof so as to extend inwardly of the chute 10 in stacked relationship with the apertures therethrough being arranged in vertical alinement when the door members 20, 21 assume a position closing the inlet 11 of the chute It) for a purpose to be subsequently described.

In accordance with the present invention, an indicator means and a latching means are incorporated in the gar huge and trash disposal devicethe indicator means informing an attendant when the container 13 is substan tially filled with refuse material so that the container 13 can be promptly emptied, and the latching means locking the door members 213, 21 in a position closing the inlet 11 of the chute 11 at the same time to avoid an overloaded condition of the container 13. To this end, a housing 25 is mounted in the building wall W so as to face toward the interior of the building, the housing 25 being preferably supported on the chute 1! at the inlet end thereof. In the latter respect, the inlet end of the chute 1t) terminates in a laterally extending marginal flange 26 having an enlarged upper border (FIGURES 3 and 4) forming a panel 27 which closes the housing 25, the marginal flange 26 being suitably secured to the interior surface of the building wall W. The housing 25 contains a solenoid 28 adapted to be energized when the container 13 has been substantially filled with refuse material, as will be subsequently described, to illuminate a light bulb 39 which is mounted in the panel 27 closing the housing 25, the light bulb 30 extending therethrough so as to be visible from the interior of the building.

It will be observed in FIGURE 3 that the solenoid 28 has a plunger 32 which is held in an extended position with respect to the solenoid housing by a coil spring 33 secured to the plunger 32 and to the top wall of the housing 25. The solenoid plunger 32 carries an actuator arm 34 extending laterally outwardly of the solenoid 28. A vertical latching pin 35 is carried by the actuator arm 34 at the end thereof remote from the solenoid plunger 32, the vertical pin 35 depending below the actuator arm 34 and disposed in vertical alinement with the apertures in the lugs 24, 24 on the door members 20, 21 when the door members 20, 21 are arranged in flush relationship closing the inlet 11 of the chute 10. As shown in FIG URE 3, when the solenoid 28 is not energized the light bulb 30 will not be illuminated and the plunger 32 will be extended by the spring 33 so as to dispose the actuator arm 34 in an upper position for retaining the vertical pin 35 in a position poised above the lugs 24, 2-4 on the door members 20, 21.

Means are provided in association with the container 13 to control energization of the solenoid 2S and thereby control the illumination of the light bulb 30 and the actuation of the latching mechanism. The control means takes the form of a load-responsive switch mechanism 36 which includes an electrically conductive annular plate 37 fioatingly suspended from the cover 14 within the container 13 by a plurality of non-conducting fasteners depending from the cover 14 and disposed about the central opening therethrough. Each of the non-conductive fasteners comprises a bolt 40 and a nut 41 threadably received about the lower end of the bolt 40. The annular plate 37 is provided with a plurality of apertures therethrough loosely receiving the bolts 40. The nuts 41 threadably received about the lower ends of the bolts 40 are of greater size than the apertures in the annular plate 37 through which the bolts 40 extend so as to retain the annular plate 37 in floating suspended relationship beneath the cover 14 of the container 13. It will be observed in FIGURES 4 and 5 that the cover 14 is provided with a plurality of electrical contact members 42 protruding below the interior surface thereof in proximity to the annular plate 37. The electrical contact members 42 are electrically interconnected by respective electrical conductors or wires extending between adjacent contact members 42.

As the level of garbage and trash accumulated within the container 13 rises in the container 13, eventually the accumulated refuse material within the container 13 will bear against the lower surface of the floating annular plate 37. Upon further accumulation of refuse material in the container 13, it will be understood that the rising level of such refuse material within the container 13 will cause the annular plate 37 to be lifted above the retaining nuts 41 and moved vertically so as to engage at least one of the plurality of electrical contact members 42 protruding from the cover 14. Upon contact being established between the annular plate 37 and one of the contact members 42, an electrical circuit is completed which energizes the solenoid 28 drawing its plunger 32 downwardly and illuminating the light bulb 30 The downward movement of the solenoid plunger 32 carries the actuator arm 34 affixed thereto downwardly to effect downward movement of the pin 35 depending from the actuator arm 34. Such downward movement of the pin 35 locks the door members 20, 21 in a position closing the inlet 11 of the chute 10, inasmuch as the pin 35 is received in the apertures formed in the overlapping lugs 24, 24 provided on the door members 20, 21. The illu mination of the light bulb 30 indicates to an attendant that the container 13 on the outside of the building wall W has been substantially filled with refuse material and should be emptied. Additionally, the locked door members 20, 21 closing the inlet 11 of the chute prevent inadvertent use of the chute 10 for discarding refuse material at a time when the container 13 requires emptying to avoid an overloaded condition of the container 13.

In emptying the container 13, an attendant raises the cover 14 by sliding it upwardly on the sleeve and removes the container 13 from beneath the cover 14. Thereafter, the contents of the container 13 are disposed of in a customary manner, and the container 13 is replaced beneath the cover 14. The act of raising the cover 14 breaks the electnical circuit for the solenoid 28 by spacing the annular plate 37 from the contact members 42 protruding from the cover 14 to tie-energize the solenoid 28. Upon de-energization of the solenoid 28, the light bulb is extinguished and the spring 33 returns the solenoid plunger 32 to the position shown in FIGURE 3 which raises the pin above the lugs 24, 24 to unlatch the door members 20, 21-thereby readying the device for subsequent usage.

FIGURES 8-11, inclusive, illustrate a modified form of the garbage and trash disposal device in accordance with the present invention, wherein a pair of refusereceiving containers are utilized with chute means. Where structural elements similar to those in the previously described form of the invention illustrated in FIG- URES l-7, inclusive, occur in the modified form of FIGURES 81l, inclusive, these structural elements have been identified by the same reference numerals employed in FIGURES l-7, inclusive, with prime notations being added thereto. Thus, it will be observed that the modified garbage and trash disposal device of FIGURES 8-11, inclusive, has a chute means 10 adapted to be installed in the wall W of a building. The chute means 10' includes a main delivery chute and a pair of branch chutes 51, 52 joined to the main chute 50 and extending downwardly therefrom. The main delivery chute 50 extends from its upper inlet end, which opens into the interior of the building, to a location disposed on the exterior side of the building wall W. There, the main delivery chute 50 is connected to the branch chutes 51, 52 which form a common connecting juncture therewith and diverge downwardly therefrom. The branch chutes 51, 52 are respectively arranged so as to dispose their outlets 12', 12 above a pair of containers 13', 13' so as to provide communication between the branch chutes 51, 52 with the interior of the containers 13', 13' through central openings in the covers 14, 14' for the containers 13, l3'the central openings being vertically alined with the corresponding outlets 12', 12' of the branch chutes 51. 52.

In like manner to the form of the invention illustrated in FIGURES 17, inclusive, connecting sleeves 15', 15 extend between the branch chutes 51, 52 and the containers 13, 13' corresponding thereto with the upper ends of the sleeves 15, 15 being frictionally received about the outlets 12', 12 of the chutes 51, 52 and the lower ends of the sleeves 15, 15' being slidably received within the central openings formed in the covers 14', 14' for the containers 13, 13' and terminating in the laterally outwardly extending retainer flanges 16', 16.

The containers 13', 13 are adapted to be alternately used for receiving refuse material depending upon the position assumed by a pivotal valve member 55 which is positioned within the chute means 10 at the juncture between the main chute 50 and the branch chutes 51, 52. The valve member 55 is adapted to be movable about a pivotal axis coinciding with the joint formed between the branch chutes S], 52 between positions alternately opening and closing the branch chutes 51, 52 with respect to the main chute 50 by means to be presently described. Referring to FIGURES 9 and 10. it will be noted that the valve member 55 comprises a pivotal plate 56 rigidly secured along its lower edge to an elongated shaft 57 having a crank arm 60 integral therewith and extending at a perpendicular angle from one end thereof. The elongated shaft 57 of the valve member 55 is appropriately journaled through the walls of the chute means 10' for oscillatory movement with respcct thereto to effect pivotal movement of the plate 56 between positions alternately opening and closing the branch chutes 51, 52.

The oscillatory movement of the shaft 57 is regulated by means of a pair of spaced apart solenoids 61. 62 disposed on opposite sides of the crank arm 60 and mounted within a housing or casing 63 secured to the exterior of the chute walls so as to extend across the juncture between the main chute 5t) and the branch chutes 51, 52, as shown in FIGURE 9. It will be observed that the spaced apart solenoids 6], 62 are provided with respective solenoid plungers 64, 65 which are connected to each other by suitable linkage 66. The crank arm 60 extending angularly from the shaft 57 of the valve member 55 is pivotally connected to the linkage 66 intermediate the ends thereof so as to be arcuately movable in response to movement of the respective solenoid plungers 64, 65 between retractedextended and extended-retracted positions upon energization or de-energization of the solenoids 61, 62 corresponding thereto. It will be understood that arcuate movement of the crank arm 60 in response to energization and de-energization of the solenoids til, 62, as will be subsequently described, imparts pivotal movement to the plate 56 through the partial rotation of the shaft 57, thereby moving the valve member 55 from a position closing one of the branch chutes 51, 52 to a position closing the other of the branch chutes 51, 52.

Referring to FIGURE 11, an electrical wiring diagram employed with the modified form of the garbage and trash disposal device for controlling movement of the valve member 55 between positions alternately opening and closing the branch chutes 51, 52 with respect to the main chute 50 and for latching the door members 21 in a position closing the inlet ll to the main chute 50 is illustrated. In this connection, it will be observed ihat each of the two containers 13', i3 is associated with its own light bulb 30 to inform an attendant whether one or both of the containers 13, 13' have been substantially filled with refuse material by the illumination of either or both of the light bulbs 30', 30.

Assuming that the modified garbage and trash disposal device of FIGURES 8-10, inclusive, is placed in operation with both of the containers 13, 13' being in an empty condition. it will be understood that the control means associated with each of the containers 13, 13' and respectively comprising an annular plate 37 suspended beneath the cover 14' in spaced relationship from the plurality of electrical contact members &2 protruding below the interior surface of the cover 14' will interrupt the electrical circuits passing through the solenoids 61 and 62 which determine the position of the valve member 55, thereby tie-energizing the solenoids 6!, 62. At this time, neither of the light bulbs 30, 30 will be illuminated. It will be further noted that the cover 14 of each of the containers l3, 13' carries another set of electrical contact members WI separate and distinct from the plurality of electrical contact members 42', the contact members 70 being arranged in a separate electrical circuit for energizing the solenoid 28 associated with the latching mechanism for locking the door members 20', 21 in a position closing the inlet 11' to the main chute of the chute means 10.

With the valve member being disposed in the position illustrated in FIGURE 8. communication between the main chute 50 and the branch chute 52 will be blocked to prevent the discharge of refuse material through the branch chute 52. of the chute means 10 and into the container 13' corresponding thereto. material will be directed through the main chute 50, the branch chute 51 and discharge through the outlet 12 of the branch chute 51 into the container 13', hereafter referred to as the first container 13', in communication with the branch chute 51. Upon the accumulation of refuse material within the first container 13' to a predetermincd level, the movement of the annular plate 37 upwardly into engagement with the electrical Contact members $2 and 79 corresponding to the first container 13 is accomplished. The engagement of the electrical contact members 42' with the annular plate 37' completes an electrical circuit through the light bulb 30' corresponding to the first container 13' and the solenoid 61 to energize the solenoid 61 for retracting the solenoid plunger 64. The cncrgization of the solenoid 61 retracting the plunger 64 causes the linkage 66 to be moved toward the solenoid til, the linkage 66 carrying the crank arm therewith to effect pivotal movement of the plate 56 for placing the valve member 55 in a position opening the branch chute 52 and closing the branch chute 51. Thus, it will be seen that the light bulb 5 3 corresponding to the first container 15 will be illuminated to inform an attendant that the first container l3 has been substantially filled with refuse material, while the branch chute 51 leading to the first container 13 will be blocltcd oil from the main chute 50 by the valve member 55 to prevent further refuse material from being directed to the first container 13', thereby avoiding an overloaded condition of the first container E3. At the same time, communication is established between the branch chute 52 and the main chute 50 to allow refuse material to be discharged through the chute means 10' into the second container 13' which acts as an auxiliary container for receiving refuse material when the first container 13' is substantially filled. The electrical circuit through the solenoid 28 is still not completed. however, because the electrical Contact members associated with the cover 14 for the other container 13', hereafter referred to as the second container 13, remain out of engagement with the annular plate 37' corresponding thereto.

Accordingly, refuse till Jill

lit

Normally, the first container 13' is emptied of refuse material at this time to permit the annular plate 3'7 associated therewith to move downwardly away from engagement with the electrical contacts 42 and '70 on the cover 14 corresponding thereto, thereby breaking the electrical circuit through the solenoid 61 and the light bulb 30 corresponding to the first container 13', and readying the valve member 55 to be returned to a position blocking the branch chute 52 leading to the second container 13' and opening the branch chute 51 when the second container 13' has been substantially filled with refuse material to cause the annular plate 37' associated therewith to engage the electrical contacts 42 and 70 corresponding thereto. In this instance, the light bulb 39 corresponding to the second container 13' will be illuminated and the solenoid 62 will be energized to draw the valve member 55 toward the solenoid 62 for closing the branch chute 52 and opening the branch chute 51, in the same manner previously explained in connection with the cnergization of solenoid 61.

In normal usage, the electrical circuit for the solenoid 28 will not be completed, since only one of the two actuating switches formed by the respective sets of electrical contacts 70 on the covers 14', 14 with the annular plates 37' corresponding thereto will be closed in a particular instance. Thus, the closure 17 will ordinarily remain unlatched so that the door members 20, 21 may be pushed inwardly to open the inlet 11 to the chute means 10' for delivering refuse material through. the chute means 10' into either the first or the second container 13' depending upon which of the branch chutes 51, 52 is in communication with the main chute 50.

Should an attendant fail to empty a container when it has been filled with refuse material, thereby allowing the solenoid 61 or 62 corresponding thereto to remain energized and the annular plate 37 associated therewith to remain in engagement with the electrical contacts 42' and 70 on the cover 14' corresponding thereto, the subsequent filling of the other container by causing the annular plate 37' associated therewith to engage the electrical contacts 70 corresponding thereto will effect the completion of the electrical circuit through the solenoid 28'. The energization of the solenoid 28' draws its plunger 32' downwardly, which carries the actuator arm 34' and the pin 35' depending therefrom downwardly, with the pin 35 being received in the apertures formed in the overlapping lugs 24' 24' on the door members 20', 21'. The door members 20', 21', are accordingly locked in a position closing the inlet 11 of the chute means 10' when both containers 13', 13' have been filled with refuse material to prevent use of. the chute means 10' for discarding refuse material at this time, and an attendant must empty at least one of the containers 13 to de-energize the solenoid 28' for releasing the latch on the door members 20', 21' before the chute means 10' can again be employed to discard refuse material.

From the foregoing description, it will be seen that both forms of the garbage and trash disposal device herein disclosed afford a convenient means for disposing of refuse materied from the interior of a building into a container located on the exterior side of the building wall, while preventing an unsanitary overloaded condition of the container.

In the drawings and specification there have been set forth preferred embodiments of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
