Manufactured by Albert E. Rinn - Allentown PA

One example was reported with a maker's name of L. F. Grammes & Sons. Another example was marked as "SAMSON" plus the patent date. A search on information on the Samson nail puller revealed that it was made by Albert E. Rinn of Allentown beginning in 1901. This patent was improved in patent 600,122, and although the Samson examples more closely resemble the later patent, they are marked with the date of this earlier patent.

Manufactured by G. B. Wheeler - Battleboro VT
Assigned to George B. Wheeler - Battleborough VT

Described construction is casting, malleableizing, and steelified, instead of forging (the common, expensive, method) which does not provide sufficient stock and strength to provide adequate torsional resistance. George B. Wheeler was Asa's son and known examples are marked G. B. Wheeler with the patent date. Asa also patented a complementary depth stop, 116901, for the countersink also assigned to George. Stanley used Wheeler's patent for the Nos. 18 and Nos. 20 countersinks which were described as being made of malleable iron (and nickle plated). The 1909 catalog only shows the "Wheeler" Wood Countersinks Nos. 18 and 20. Available by 1916, the No. 23 and No. 24 countersinks are described as superior steel forged tools making it highly unlikely the patent applied to their construction or that the countersink would be still marked with the patent number 46 years later although graphically they appear the same.
