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.

1,278,865 Sep. 17, 1918 Dynamo-electric machine James F. Curtis Pitcairn, PA "The object of my invention is to simplify the structure and reduce the expense of manufacture of dynamo-electric machine rotors. In the prior art, the rotors of certain types of dynamo-electric machines have been provided with sets of fan blades for the purpose of directing currents of cooling air through certain portions of the machine, the blades being either individually attached to the outer surface of the rotors or being secured to annular bands, which, in turn were attached to the rotor bodies; also, separate wiper rings were disposed around the machine shaft for the purpose of expelling any excess oil... According to my invention, I provide an integrally combined wiper ring and set of fan blades..."

1,300,243 Apr. 15, 1919 Dynamo-electric machine Aubrey L. Broomall Wilkinsburg, PA "...it has been found that, when the motor was operated in an exposed position, such as on an electric motor-driven vehicle, both dirt and moisture entered the machine through the ventilating openings, and came into contact with the current-carrying parts. By my invention, I provide a cover for ventilating openings so constructed that the air passing therethrough is deflected away from the current-carrying parts."

4,718,172 Jan. 12, 1988 Turbine Blade Radial Position Gage Marshall J. Rouse Charlotte, NC Abstract
A gage for determining alignment of a turbine rotor blade in an assembly position on a turbine rotor. The gage includes a precision base for positioning on the rotor surface adjacent a blade to establish a tangent line perpendicular to a rotor radial line through the center of a slot in which a blade is disposed. A standard extends from the base and carries a first contact for positioning against a low portion of the blade and a second measuring contact for positioning against an upper portion of the blade. The measuring contact provides an indication of blade misalignment.
