Bullard Automatic Wrench Company (Providence, RI)
Article from Power, 1/14/1908 on the Bullard Wrench. All of the advertisements match the wrench described in a Frank D. Bullard Patent #742,389 - Pipe Wrench. However, in the same year Mr. Bullard was awarded two different pipe-wrench design patents: Patent #729,728 and Patent #733,138. Here is an article from the 12/29/1904 edition of Iron Age explaining the operation of the wrench. On May 20, 1909 the factory was auctioned off. For a very short time Roren Drop Forge & Wrench Company (Providence, RI) produced a "Bullard" wrench in 1910. According to one source, Albert Roren was the former superintendent of Bullard, but we have found no evidence of this.
