This nifty little tool dates from the pre-"cordless drill" days, back in the age when using an electric drill usually also required using a long extension cord. :-)
It measures about 4" long (without bit) and 2" across, with an aluminum exterior housing. When clamped into a drill, it serves as a sort of 'clutch' which allows driving screws -- the "screwdriver bit" end only rotates when 'pushed on' via the (already rotating, or not) drill motor on its other end -- a natural action needed to drive screws (or drill holes, for that matter) no matter what provides the 'twisty power'. (a drill, or one's wrist/arm, or whatever) Different kinds of screwdriver bits can be used with it, the exact style of bit also fits large "Yankee" mechanical hand-operated screwdrivers of the era. Two such bits are pictured, one actually "YANKEE" branded and the 2nd made by "GREENLEE".
Around its midsection it reads: CRAFTSMAN "60". Around the screwdriver end of the housing, in smaller type, is SEARS, ROEBUCK AND CO. U.S.A. SIMPSON-SEARS LTD. CANADA. I'm guessing it dates from the 1960's, but it could easily be a little older or newer.
