Brace B&D-41:
|
|
The wrist handles of the two Stanley
No.921-14IN braces have different methods of affixing the wrist handles.
The present brace appears to follow Albert Goodell's US Patent No. 488,691,
dated December 27, 1892, and not George Allen's US Patent No. 675,917,
dated June 11, 1901, as the latter was assigned to the Peck, Stow &
Wilcox Company, and the former had probably expired by the time this
brace was made, as early as 1918.
