Key to Links for Patent Information

USPTO = U.S. Patent Office . Images of the actual patent can be viewed on the U.S. Patent Office web site but a special TIFF viewer must be installed with your browser in order properly work. More information on how to configure your computer to view these patents can be found at TIFF image Viewers for Patent Images.
DATAMP = Directory of American Tool And Machinery Patents . A sister site to VintageMachinery.org with information on patents related to machinery and tools. A much easier user interface than the USPTO's for finding information on machinery patents.

862,437 Aug. 06, 1907 Lathe Henry Bertram ON, Canada James W. See - patent attorney
Under modern conditions of lathe use, in which remarkably heavy cuts are taken with the recently developed high-speed steels, there has developed a tendency for the lathe arbor to spring into a deflection between its bearings. With extra heavy work being done at the face plate, either boring: or turning, the tendency is for the nose of the arbor to spring upwardly and deflect the central portions of the arbor, between its bearings, downwardly. My present invention aims to so stiffen the arbor as to lessen the evil referred to.

117,209 Mar. 16, 1909 Metal planer Henry Bertram ON, Canada "My invention pertains to metal planers and relates to improvements in the mounting of the side-heads to facilitate the side-heads being rigidly supported when projecting their tools far inwardly from the housings on which they are mounted."
927,628 Jul. 13, 1909 Means for securing movable lathe-stocks Charles Duncanson Young Columbus, OH The Canadian equivalent of this patent is 122,545 and is assigned to the Ontario machine tool manufacturer John Bertram & Sons. We don't know if this patent was used by an American manufacturer, nor do we know how the inventor connected with a Canadian machine tool maker. The inventor, Charles Duncanson Young, would later (in the early 1920s) become commanding officer of the US 304th Engineer Regiment. He was recalled to duty sometime before the US joined World War II. In 1942 he was promoted to Brigadier-General. He spent the war working in procurement, distribution and transportation. He was released from active duty in 1945. In 1948 he received a Franklin Institute Award for his work on "Scientific Advancement of Steam Locomotive". He died in 1955 just before his 77th birthday.
