Jeff Joslin Vintage Machinery entry for F. E. Reed & Co. "Machinery" article on this invention
|
Description: |
The February 1906 "Metal Industry" summarizes this patent as follows. "The essential feature of the mechanism consists of a floating cone of gears. Preferably this cone is held against longitudinal movement and is arranged to co-act with the axially driven member or the axially movable driven member, or both. These driving and driven members, which take the form of gears intermeshing with the cone gears, are mounted to slide upon shafts and are movable past each other so, that the different combinations which may be effected for securing different speeds are determined by the number of gears in the cone. It is stated that this feature of the invention is peculiarly applicable in lathe or screw cutting machines as it makes possible the formation of threads of any desired pitch or lead."The May 1906 "Machinery" has a brief illustrated article on this invention, which notes that the inventor had relocated to Phoenix, Md. Shop rights were being exercised by F. E. Reed Co. "Shop right" to an invention is a non-transferable and non-exclusive right to use an employee's invention that was made using an employer's time, materials, facilities or equipment. |
