I have always had a great fondness for North Bros. "YANKEE" tools. I have owned and used many during my lifetime and have always found them to be superbly made and of the highest quality.

Tool Markings

North Bros. always used that form of their Company name in marking their tools. "YANKEE" was always rendered that way -- never without the quotes or in lower case lettering. The layout and arrangement of stampings varied from tool to tool.

"YANKEE" (Tool No.) NORTH BROS. MFG. CO. PHILA. PA. U.S.A. (followed by Patent dates)

In 1946 Stanley Tools acquired North Bros. Mfg. Co. and subsequently stamped "Yankee" tools as follows:


Note: I am not sure how the Stanley "Made in England" (Sheffield) "Yankee" tools were stamped.

In 1959 Stanley closed the North Bros. Philadelphia plant and moved "Yankee" Tool production to New Britain, Conn thereafter stamping the tools as follows:


Tool Finish

Exposed metal surfaces were painted black or dark gray enamel or nickel/chrome plated unless otherwise noted.

The nickel plating on early "YANKEE" tools often wore off with use to expose the brass under lay. WWII production tools were not plated in order to conserve nickel which was a war-essential commodity - the metal surfaces were often blued, painted or simply left as lightly polished brass - aluminum was sometimes substituted for steel where practical.

"YANKEE" decals were affixed to all pre-1924 spiral ratchet screwdriver hardwood handles which were originally finished with what appears to be reddish brown stain/lacquer or varnish (not specified by the Company) as were hand drill handles and knobs.

"YANKEE" was impressed on the side of "A" suffix screwdriver handles. This stamping was often weakly struck and became hard to distinguish after much use. The finish color on these handles (similarly for "A" suffix hand drills) has been described by some as cranberry.

"YANKEE" tools were packaged and sold in substantial cardboard packing boxes to which were affixed yellow paper labels that described how to use the tool and outlined it's features. Accessories were wrapped in plain paper or enclosed in brown paper envelopes.

Three very imaginative and talented inventors designed innumerable (mostly ratchet) hand tool mechanisms and assigned their patents to North Bros:

Furbish worked mostly alone, but Leopold and Fegley frequently collaborated in producing their designs.

The Directory of American Tool And Machinery Patents Search Facility is an outstanding tool for researching patents by Patentee, Assignee, Manufacturing Company ..... and so on.

There is one more Patent assigned separately to North Bros. - US Patent: 1,059,132 Means For attaching handles to tools - bit storage handle for the North Bros. (e.g. 1530 & some 14xx series) eggbeater drills.

Patents expired after twenty years from the date of issuance. After that the design was consigned to the Public Domain.
