Description: |
| The design features patented are the shape of the central recesses in the shank and head of this carriage wrench.
The Eberhart Mfg. Co. of Cleveland made wrenches matching this design in a range of sizes. Markings include the company logo (a circled E), the letters PAT*D, and a part number of four digits (7320 for the "deep pattern") and a letter which corresponds to a standard size for the "box end." Illustrations from an early Eberhard catalog are shown on pg. 155 of P.T. Rathbone's "History of Old Time Farm Implement Companies and the Wrenches They Issued," vol. 1.
Pope received 30 consecutive design patents for malleable iron buggy and carriage parts on Nov. 14, 1882 (D13,406 - D13,435), including four wrench designs (this patent and D13,430, D13,434, and D13,435).
Similar "deep pattern" carriage wrenches with the same design number 7320 were produced by several malleable iron manufacturers including Illinois Malleable Iron Co. and Pratt. |
