Frame for saw-tables

George L. Knights |
Amesbury, MA |
An undated catalog from Pettingell Machine Co. features their No. 22 Large Bevel and Mitre Saw, "patented June 16,1910". That is not a valid patent date (since the patents are only issued on Tuesdays) and the illustrated machine is a virtually exact match to this patent drawing. The patent specification refers to the basic saw design as the "Howard saw table" (patent 183,397, and the innovation is the step in the horizontal footprint so that someone using the sliding table does not have to lean or step over the saw frame. |

Machine for bending metallic plates

George W. Wells |
Amesbury, MA |
This patent date was seen on an "Open End Cornice Brake" in a catalog from Pettingell Machine Co. The illustration shows the Pettingell name cast into the base of the machine.
The assignee company, Walker-Wells Co., was formed in 1911 to take over the Amesbury operations of the Walker Carriage Co. Walker-Wells made automotive bodies and were quite successful in their early years. Harlan P. Wells was president, and the other executives were George Walker, James H. Walker, and Henry Miller. Given their specialty, it seems unlikely that Walker-Wells ever manufactured this cornice brake. |
