Machine for cutting miters
|
Stephen W. Hall |
Williamsport, PA |
This important patent was granted an extension. Many examples of this miter chopper have been reported, and from a variety of makers. S. W. Hall made it for many years, and the design was licensed to Ransom Crosby of Newark, and then Hawkins & Dodge, also of Newark. Eventually the rights went to Seymour & Whitlock of Newark, who arranged for the patent to be extended. H. C. Marsh also made this design (whether this was after Seymour & Whitlock or at the same time, I don't know) and then Stanley Rule & Level bought out Marsh. This trimmer design was then sold as the Stanley No. 210.
"I do not claim as my invention the use of the knives A, A, adjusted at right angles and attached to the sliding rest B, since the same arrangement substantially is shown in the combination patented by George Le Baw June 27th, 1854 (patent 11,164), but what I do claim as new and of my own invention is— 1. The use in miter machines of the flanges G, G, and the groove x in the frame E, E for the purpose of guiding and sustaining the outer and inner edges of the knives A A, and preventing them from springing substantially as herein set forth. 2. I claim the combination together of the flanges G, G, and frame E, E, with the groove x, and sliding rest B, substantially in the manner and for the purpose herein set forth."
