Removable Debris Receptacle Patents (Class 29/DIG79)
  • Patent number: 5916334
    Abstract: A bottom guard for a machine having a plate with a hinged side pivotably attached to a first frame member of a machine and a catch side opposite the hinged side releasably held near a second frame member by a latching device. The plate holds debris from the operation of the machine and serves as a safety guard. The latching device has a first portion attached to the second frame member and a second portion attached to the catch side of the plate. The two portions of the latching device mechanically interlock and a solenoid actuated mechanism releases them upon a remote signal to the solenoid which allows the catch side of the plate to move by gravity, thereby opening the guard and discharging accumulated debris to a side of the machine. At least one shock absorbing device, such as an elastomeric shock cord, a pneumatic cylinder, or a hydraulic cylinder limits the amount that the plate will swing open when the catch is released and cushions the plate as it falls open.
