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.

Patent Number	Date	Title	Name	City	Description
131,669	Sep. 24, 1872	Improvement in scroll-sawing machines	Thomas Wickliffe Dowling	Pontiac, MI	See also Canada patent {CA3,141}.
145,993	Dec. 30, 1873	Improvement in scroll-sawing machines	Thomas Wickliffe Dowling	Pontiac, MI
3,141	Feb. 24, 1874	Improvements on scroll-sawing machines	Thomas Wickliffe Dowling	Pontiac, MI	This is the Canadian equivalent of US patent 145,993. The 1886 "Illustrated Catalog of Machinists' Tools and Wood Working Machinery" from John Bertram & Sons, pages 40-41 features Dowling's Patent Scroll Sawing Machine. "Having purchased the exclusive right to manufacture this machine in the Dominion, we can confidently recommend it... The saw has a constant strain through its whole stroke. This is effected by two spiral springs acting on steel levers which are attached to the upper slide direct, and all the reciprocating parts of this movement being made of steel-plate enables the machine to run at a high rate of speed with great smoothness..."
629,539	Jul. 25, 1899	Boring and excavating implement	John Bertram	ON, Canada
95,988	Nov. 07, 1905	Lathe driving mechanism	Charles George Draeseke	ON, Canada
98,742	Apr. 24, 1906	Variable speed gearing	Willard Thomas Sears	Philadelphia, PA
99,422	Jun. 05, 1906	Counter balance	William Joseph Hagman	Philadelphia, PA
105,241	May. 14, 1907	Wheel press	George Theodore Reiss	Hamilton, OH
105,414	May. 21, 1907	Car wheel press	James Kenmore Cullen	Hamilton, OH
		Car wheel press	George Theodore Reiss	Hamilton, OH
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.
122,545	Dec. 14, 1909	Means for securing movable lathestocks	Charles Duncanson Young	Columbus, OH	This is the Canadian equivalent of US patent 927,628.
