  • Patent number: 4083477
    Abstract: An elongated cylinder having a hollow cylindrical extension member received press fit in a discharge open end thereof normally receives an elongated plunger in an opposite receiving open end with said plunger having a piston-like end within the cylinder selectively slideable along the cylinder to dispense fish bait of putty-like consistency from the cylinder through the extension member. The cylinder preferably has a uniform outer cylindrical surface except for an annular, outwardly projecting portion at the plunger receiving end thereof and a finger gripping ring is telescoped over the cylinder outer surface selectively slideable therealong movable to the cylinder plunger receiving end against the outwardly projecting portion for normal bait dispensing use of the cylinder and plunger, but movable to the cylinder discharge end for removal of the plunger from the cylinder and insertion of the cylinder plunger receiving end into a supply of fish bait to fill the same.

  • Patent number: 3973584
    Abstract: Upper and lower blocks with registering grooves are assembled about a pipeline with an upper block piercing needle moved downwardly piercing the pipeline. The piercing needle is then moved upwardly providing communication through the pipeline pierced hole and into a transfer passageway of the upper block. A resilient O-ring is positioned within an annular chamber spaced outwardly of a lower portion of the piercing needle compressed upwardly against the upper block and downwardly against the pipeline to seal the upper block groove from the pipeline pierced hole. The lower block groove is formed semi-circular in transverse cross section and the upper block groove is formed semi-elliptical in transverse cross section with the pipeline being deformed totally conforming to the block grooves when the blocks are brought into assembled abutment.
