Description:
The jar opener size is set by a pawl on a lever handle attached to the movable jaw. The pawl engages one tooth of a rack of teeth cut in the interior edge of one frame rod. The patent includes an opener for clamp-on container tops.

One known example marked "MADE IN U.S.A. Pat. No. 2000962" has only the adjustable jar wrench portion.

A second known example marked "MADE IN U.S.A. Pat. No. 2000962" also includes the second lid lifter type opener shown in the patent drawing and a "stab the center and cut along the rim" type can opener. That style of can opener is elaborated in Krag's Sept. 2, 1941 patent (no. 2,254,533).

A third known example marked "JAR AND CAN OPENER" incorporates a different style can opener on the end.
