  • Patent number: 6253969
    Abstract: A housing has a first, dispensing end and a second, opposite end. A lever is squeezed against the housing to move a plunger toward the dispensing end. When fully squeezed, the lever extends parallel to the plunger and the longitudinal axis of the housing. The extent to which the plunger advances may be adjusted by relocating the pivot axis defined between the lever and the housing. A resilient washer is mounted on the shaft of the plunger and disposed behind a shoulder on the housing. The resilient washer deflects and/or stretches forward when the plunger advances, and urges the plunger rearward upon release of the lever.

  • Patent number: 5806237
    Abstract: A rodent bait station includes an enclosure having an inclined passageway leading from an opening in the enclosure to an elevated bait receptacle having a removable tray with a handle. The inclined passageway terminates at the lowest elevation of the opening to prevent water from becoming trapped in the enclosure. A separate internal receptacle is provided in the enclosure for storing and protecting printed materials, e.g., maintenance records. A replaceable latch on the enclosure includes an alignment member disposed between a pair of engagement members which engage cooperative slots and which are deformable to unengaged positions by a key that wedges between the engagement members and the alignment member.
