2. New Construction The most advanced kno~n method of multi-~tory separated waste collection~ for recycling in new ,~
- `
20~485 1 W092/0161~ PCT/US91/04217 build1ngs consist~ of in~talling multiple chutes, one chute for each type of ~eparated waste, such a~ glasq, paper, aluminum and the like. ~hiq method takes up a great deal of space, is expensive, requires comm1ngling of recyclable~ if less than the bare min~mNn o~ five chute~ are u~ed (three chutes are currently proposedr aq a standard) and is not expandable to a larger number of separate categories in the future. In short, this method is nearly as limiting aa the currently used one-chute system.
The current methods consistantly qhow lo~ generation rates and low participation because they ignore the tenant as the primary separator of solid wastes.
Diselosure of Invention it ls aceordingly an object of the invention to provide a system that allows the tenant to separate non-co =ingled recyclables conveniently by duplicating the eurrent habitual aet of carrying a ba~ket of waste to the trash chute and dumpi~g the waste.
By eausing the tenant to separate recyelables, the invention avoids the labor eost to separate reeyclables later, avoids the labor eo~t to piek up eontainers on ~`~
eaeh floor, and avol~s the labor oost of eonsolidatlng the waste at a single eentral loeation.
Using this invention, the containers of reeyclable~ ;
may be rolled and lifted onto a simple flatbed trailer attaehed to an e~isting front end loader garbage tru¢k and the eontainer~ of non-reeyclables may be dumped into the garbage true~. ~his allows for removal of re-¢yclableQ from the building at the same time using e~lsting e~uipment at redueed labor eosts.
~ he system of the invention ineludes a ~ingle vertieal waste ehute aeeesQed by a door at each floor to take advantage of e~istiDg struetures and reduce eosts in new eonstruetion. At the bottom of the ehute, a motor moves a plurallty of waste reeeptacles, one dedieated to eaeh type of waste. Control means at each floor seleets a particular re¢eptacle to be moved to a position beneath WO92/01615 2 ~ ~ ~ 8 ~ 4 PCT/US91/04217 the chute to recei~e a particular type of waste material.
Controlq and interconneeting mean~ prevent movement when a door i9 open, indicate to eaeh floor whieh i,~

Beneath the chute 1, in the basement, a plateform ~ holds a set of waste receptacle~ 7, one for each type of separated waste, such as clear glasc, colored glass, aluminum, paper and all other wastes or garbage. The mo~able platform ~ is a turntable that is rotated by motor 5. A position sensor 6 senses the rotary position of the platform ~. ~he central control 12 operat~s the motor 5 that cooperates with the position sen30r 6 in a servo relationship to rotate the platform ~ until the selected (paper) receptacle iq directly beneath chute 7.
A door sensor and lock a_qembly 13 at esch door 2 -~
is also connected to the central control 12. While the platform i9 mo~ing, the central control 12 actuates all the door lockq to prevent waste falling while receptacles are mo~ing. If any door is open, its door sensor will communicate that in~ormation to the central control 12 which may inhibit operation o~ tor 5 and platform motion.

lights 29. A power ~upply l9 for the sy~tem i~ powered by the line power and the electronic control~ in the central control 12 may be of the programmed microprocessor type with multiple inputs that i9 well known ~n the art. It may indicate service problems and may telephone for service.
The receptacles 7 may be provided with wheelQ 20 for ease in rolling down ramp 21 when full.
A~ shown in Fig. 2, the mo~ing platform ~ may be of the rectilinear type that moves bac~ and forth in a straight line to better accomodate space and geometry requirement~ of certain installations. As shown, the platform ~ may have a plurality of shallow, uni~uely-shaped recesses 26 in its upper surfaoe for recei~ing a corresponding set of uniquely shaped receptacles (not shown). ~his feature ensure3 correct positioning of particular receptacles.
Referring now to Fig. 3, certain containers 22 may be taller and of smaller diameter with a notch 23 cut into the upper opening. This notch 23 holds a trough 2~
that leadq to the much larger and lo~er garbage ``
receptacle 7.
When the low-~olume, low-use receptacle is full, the excess will flow into the much larger garbage receptacle. This option permits use of larger receptacles for high volume item~ and smaller receptacles for low volume u~e for more efficient platform space utilization without fear of overflow.
A distinct ad~antage of a progrsmmable microprocessor with multiple inputs and outputs in the central control 12 of ~ig. 1 is that provisions csn be made æt neglibible cost for the future inclusion of additional categories of separated wastes. If a category i 8 added, then an additional pushbutton and light for that category must be added at each control panel and the neces-~ary wiring connections made. The cost of adding e~tra categories will be even less if the initisl in~tallation i9 made ~ith the wiri~g, pushbutton and lights for several extra categories and the final f~ V V ``~
W O 92/01615 PC~r/US91/~4217 connections at the central control 12 placed on internal switches well ~nown in the art. In that case, adding a category ~imply invol~es applying labels to the lights on each control panel 11, and opening the central control 12 to operate a concealed switch 30 to compl~te the connection.
The particular se~uences of operation, timing intervals and the like are controlled by the program in ;~
the microproceqsor. The manufacturer of the system may -~
provide various options that may be implemented by simply replacing the program. This may in~olve ~-replacing a Qeparate program module or the microproceqsor module when the program is on the chip with ~he microprocessor. The program may include variouq optionq such as a default position wherein the -garbage receptacle is moved into position when there is, for e~ample, a problem with loc~ing a door.
The microprocessor may be programmed for ~ophi~ticated ~ervice functions such aq:
displaying the nature of a dysfunction; ~;
telephoning o~f-site for service;
increasing time delay for higher floor3 to allow time for refuqe to fall;
signalling when a particular door is left open, and the like.
Referring now to Fig. 4, a rotary platform 4 holds a plurality of receptacles 7 that are wedge-shaped for enhanced capacity in a compact arrangement. Suspendéd o~er the receptacles i~ a ram or plunger 31 arranged to be directly over the open top of a receptacle as the platform rotates. ~he plunger 31 is dri~en up and down by power drive 32 acting on rack 33. The plunger 31 i9 arranged to compress the waste on the down stroke to thereby increase the capacity of the system and reduce the ~olume of ~te for redu¢ed dispoaal costQ. The plunger-31 has a pyramidal top portion 34 to reduce trapping of waste thereon. The receptacles 7 are provided with handling means for emptying by both rear end loading truc~s with lifting hooks and side loading ~4~O92/0161~ PCT/US91/04217 truc~q. An eye 35 receive~ the lifting hook of a rear end loader. A handle asqembly 36 include~ an upper bar 37 that projects upward and outward to serve aq a fulcrum for tilting the receptacle up as the eye is lifted.
The upper bar 37 also serves as the lifting bar for side loading truc~s in combination with the lower bar ~7 that serves as the loc~ing element when the receptacle is tilted by the side loading truc~
~ he above diqclosed invention has a number of particular features which should preferably be employed in combination although each is useful qeparately without departure from the scope of the invention.
While I have shovrn and described the preferred embodiments of my invention, it will be understood that the invention may be embodied otherwise than as herein ~pecifically illustrated or described, and that certain changes in the form and arrangement of parts and the ~-~

When the low-~olume, low-use receptacle is full, the excess will flow into the much larger garbage receptacle. This option permits use of larger receptacles for high volume item~ and smaller receptacles for low volume u~e for more efficient platform space utilization without fear of overflow.
A distinct ad~antage of a progrsmmable microprocessor with multiple inputs and outputs in the central control 12 of ~ig. 1 is that provisions csn be made æt neglibible cost for the future inclusion of additional categories of separated wastes. If a category i 8 added, then an additional pushbutton and light for that category must be added at each control panel and the neces-~ary wiring connections made. The cost of adding e~tra categories will be even less if the initisl in~tallation i9 made ~ith the wiri~g, pushbutton and lights for several extra categories and the final f~ V V ``~
W O 92/01615 PC~r/US91/~4217 connections at the central control 12 placed on internal switches well ~nown in the art. In that case, adding a category ~imply invol~es applying labels to the lights on each control panel 11, and opening the central control 12 to operate a concealed switch 30 to compl~te the connection.
The particular se~uences of operation, timing intervals and the like are controlled by the program in ;~
the microproceqsor. The manufacturer of the system may -~
provide various options that may be implemented by simply replacing the program. This may in~olve ~-replacing a Qeparate program module or the microproceqsor module when the program is on the chip with ~he microprocessor. The program may include variouq optionq such as a default position wherein the -garbage receptacle is moved into position when there is, for e~ample, a problem with loc~ing a door.
The microprocessor may be programmed for ~ophi~ticated ~ervice functions such aq:
displaying the nature of a dysfunction; ~;
telephoning o~f-site for service;
increasing time delay for higher floor3 to allow time for refuqe to fall;
signalling when a particular door is left open, and the like.
Referring now to Fig. 4, a rotary platform 4 holds a plurality of receptacles 7 that are wedge-shaped for enhanced capacity in a compact arrangement. Suspendéd o~er the receptacles i~ a ram or plunger 31 arranged to be directly over the open top of a receptacle as the platform rotates. ~he plunger 31 is dri~en up and down by power drive 32 acting on rack 33. The plunger 31 i9 arranged to compress the waste on the down stroke to thereby increase the capacity of the system and reduce the ~olume of ~te for redu¢ed dispoaal costQ. The plunger-31 has a pyramidal top portion 34 to reduce trapping of waste thereon. The receptacles 7 are provided with handling means for emptying by both rear end loading truc~s with lifting hooks and side loading ~4~O92/0161~ PCT/US91/04217 truc~q. An eye 35 receive~ the lifting hook of a rear end loader. A handle asqembly 36 include~ an upper bar 37 that projects upward and outward to serve aq a fulcrum for tilting the receptacle up as the eye is lifted.
The upper bar 37 also serves as the lifting bar for side loading truc~s in combination with the lower bar ~7 that serves as the loc~ing element when the receptacle is tilted by the side loading truc~
~ he above diqclosed invention has a number of particular features which should preferably be employed in combination although each is useful qeparately without departure from the scope of the invention.
While I have shovrn and described the preferred embodiments of my invention, it will be understood that the invention may be embodied otherwise than as herein ~pecifically illustrated or described, and that certain changes in the form and arrangement of parts and the ~-~
specific manner of practicing the invention may be made within the t~nderlying idea or principles of the invention ~ithin the ~cope of the appended claim~
