  • Patent number: 8474591
    Abstract: The garbage chute apparatus provides a chute of about 12 inches in diameter that is smooth with the rounded bend relatively gradual so that garbage items do no lodge within the chute or become trapped by any rough or uneven surfaces. The deodorizer within the chute further provides odor protection. The exhaust fan also prevents odor buildup. The coupler removably and sealably fits to the chute vertical leg via a hook and loop band, so that the coupling between the chute and coupler is leak proof with regard to odors and materials. The smooth bell-shaped coupler has no surfaces aberrations so that garbage items are not lodged, but pass straight through. The coupler opens widely at the bottom to allow for removable attachment to a plurality of garbage containers, with little regard to container size and shape. The elastic band seals the coupler to a given container.

  • Patent number: 3948374
    Abstract: A reproduction machine having a document scanning system has an improved recycling clutch for operating the system. The clutch has a rotatable input plate and a rotatable output plate. An annular pawl plate pivotally mounted on the input plate has a driving surface which is biased into engagement with a pin on the output plate. A rotatable timing element driven by the input plate periodically contacts a cam surface on the outer periphery of the pawl plate to disengage the driving surface from the pin to effect release of the clutch at intervals greater than a revolution of the input plate. The cam surface maintains the disengagement of the driving surface from the output plate for a sufficient length of time to permit rotation of the latter in the reverse direction greater than one revolution via a biasing spring.
