Lufkin Reliable Junior Tape Measure

<< >>
This 25-foot metal tape measure is divided to 1/16". The first 3" of the tape has broken off, and white cloth tape is wrapped around the broken end. At 6" the back of the tape is marked: LUFKIN. A brown leather case is marked on both sides: RELIABLE JUNIOR (/) PATENTED (/) 25 FT (/) LUFKIN RULE CO. (/) SAGINAW, MICH. USA. Pressing a metal button on one side of the case causes the metal crank handle on the other side to pop out. This handle is wound clockwise to retract the measure. It is marked: PATENTED (/) MAY 23, 1893.
The Lufkin Board and Log Rule Company of Cleveland, Ohio, began making steel tape measures in 1887 and moved to Saginaw, Mich., in 1892. Fred Buck (1858–1938), the company's general manager, applied for a patent on an extending crank attached to a revolving drum in 1892 and received it the next year. He received a second patent for a tape measure crank in 1907 that was advertised on the Reliable Junior product line by 1916. By 1903, Lufkin was the largest manufacturer of steel measuring tapes in the United States. The brand was taken over by Cooper Industries in 1967. The donor found this particular rule in a trapper's cabin in the mountains of British Columbia.
