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.

867,168	Sep. 24, 1907	Controller-regulator	Emmett W. Stull	Norwood, OH	"My invention relates to motor controllers and particularly to means for regulating the operation of controllers for railway motors."
868,596	Oct. 15, 1907	Potential-starter attachment	Herbert W. Cheney	Norwood, OH
870,595	Nov. 12, 1907	Controller	Lewis L. Tatum	Norwood, OH
870,596	Nov. 12, 1907	Motor-controller	Lewis L. Tatum	Norwood, OH	"My invention is especially applicable to mill motors and mine hoists where it is necessary to frequently stop, start and reverse the motors. It is also well adapted for use upon electric locomotives and in all places where large currents or high voltages are to be controlled."
871,193	Nov. 19, 1907	Arrangement for motor-drives	Emmett W. Stull	Norwood, OH	"In many places where electric motors are used it is essential that there be no break in the continuous operation of the system. Such is the case for instance in rolling mills, where a breakdown in the operating mechanism often causes a great loss due to the cooling down of the heated metal. In this rolling mills it is absolutely essential that the process be continuous. I have provided a system in which, in case of the breaking down of the driving motor, an emergency motor may be connected to the device to be driven, the injured motor being disconnected both mechanically and electrically so that it may be removed and repaired at leisure."
871,220	Nov. 19, 1907	Controller	Thomas Gilmore Jr.	Norwood, OH	"My invention relates to controllers for electric motors and particularly to series-parallel controllers of the drum type. In the operation of modern electric railway cars, especially those employed in inter-urban traffic, a number of motors, usually four, are required. These motors are of large capacity and draw heavy currents from the line and the difficulty of handling and properly controlling the current supplied to them becomes very great..."
871,904	Nov. 26, 1907	Shaft-oscillator	Edwin C. Wright	Newport, KY	"My invention relates to shaft oscillators or end-play devices. It is particularly adapted for use in connection with dynamo-electric machines for the purpose of preventing grooving and roughening of the commutator."
871,970	Nov. 26, 1907	System of motor control	Emmet W. Stull	Norwood, OH	"My invention relates to controllers for electric motors, and particularly to railway controllers of the type adapted to control a plurality of motors. One of the objects of my invention is to enable injured or disabled motors to be cut out of circuit without affecting the action of the controller upon the remaining motors..."
872,641	Dec. 03, 1907	Shaft-oscillator	Will F. BouchÃ©	Norwood, OH	"An oscillating movement given to a rotating element of a dynamo-electric machine, especially a rotary converter, causes the shaft of said element to operate in its bearings and prevents the wearing of the ridges and grooves in the commutator of the machine."
909,136	Jan. 12, 1909	Dynamo Electric Machine	Bernard Arthur Behrend	Norwood, Hamilton County, OH
909,216	Jan. 12, 1909	Means for Starting Dynamo Machines	William D. Pomeroy	Norwood, Hamilton County, OH
917,471	Apr. 06, 1909	Induction-motor	Emil Mattman	Norwood, OH
925,271	Jun. 15, 1909	Core Spacing for Dynamo Electric Machines	Bernard A. Behrend	Norwood, Hamilton County, OH
925,272	Jun. 15, 1909	Dynamo Electric Machine	Bernard A. Behrend	Norwood, Hamilton County, OH
925,392	Jun. 15, 1909	Dynamo Electric Machine	George B. Schley	Norwood, Hamilton County, OH
934,210	Sep. 14, 1909	Dynamo-electric machines	William D. Pomeroy	Norwood, OH
960,347	Jun. 07, 1910	Belt-tightener	Arthur F. Kwis	Norwood, OH
145,515	Jan. 28, 1913	Dynamo electric machine	David Hall	Norwood, OH	This double-commutator motor addresses a problem common to that type of device where a winding that happens to carry slightly more current will heat the brushes which causes lowered resistance and will then carry yet more current, and this positive feedback continues until the one winding carries nearly the entire load. The inventor adds auxiliary windings connected in a way to counteract this effect.
