Description: |
| Reversible ratchet with special features suited to its primary function as operating wrench for railroad hopper car doors.
Advertising from 1914, 1915 and 1920 supplies names of two successive manufacturers. A more recent example (5th image) was made by LOWELL WRENCH Co -- "The Lowell SWACO Hopper Wrench weighs almost 30 lbs. It's 36" long & the ratchet head is 6." across."
G.M. Gealy's I.X.L. SAFETY WRENCH (pat. no. 1,244,596) was a competitor. |
