Pull tab attachment tool

A pull tab attachment tool comprising:

• a. a pair of first and second levers having respectively first and second handle portions and opposed first and second jaw portions extending from their one ends in a common direction, said first and second levers being pivotably connected together adjacent to said one ends thereof, said second lever having a roller intermediate the opposite ends thereof, and said first lever having an outwardly opening pull tab-receiving slot at said one end thereof which also opens in a direction away from said first jaw portion and defines a pair of laterally spaced apart seat surfaces at its opening facing away from said first jaw portion;
• b. a third lever pivotably connected to the other end of said first lever, said third lever having an outwardly-opening punching depression at one end thereof, and said depression facing said pair of seat surfaces;
• c. an urging means acting between said first and third levers and normally urging said third lever away from said first handle portion whereby said third lever is held in rolling engagement with said roller to spread said first and second handle portions apart with said opposed jaw portions held away from each other;
• and
• d. whereby when said first and second handle portions are manually actuated to move toward each other, said opposed jaw portions are brought into engagement with each other to provide a first pressing structure, and said one end of said third lever is brought into engagement with said one end of said first lever through the rolling action of said roller along said third lever, with said punching depression in alignment with said pair of seat surfaces to provide a second pressing structure.
