Title: Improvements in Lock Nuts.
Inventor: GLOSSOP GEORGE
Filed: 1904-09-06
Granted: 1905-07-06
Abstract: 19,238. Glossop, G. Sept. 6. Making nuts.-Square or hexagonal locking-nuts are made from iron, steel, or other metal in such a manner that, when screwed on to a bolt either side uppermost, a dislocation or discontinuity in the thread of the bolt hole causes parts of the threads to bind, thus locking the nut. The bar of metal for a number of nuts is formed by rolling and pressing into the finished shape shown in end view in Fig. 5, in which a longitudinal L-shaped slit or crease C extends so that it will be intersected by the bolt hole. In Fig. 7 is shown a form in which the metal, in shaped pieces, is grooved by a punch, the sides of the groove being then pressed together. The slit, crease, or groove in either case is approximately half the depth of the nut. The bolt hole is finally drilled, or punched, and tapped, in which process the slit or crease in the nut at the two sides of the bolt hole causes the thread to be dislocated.

Title: Improvements in Dynamo Electric Machines
Filed: 1904-11-25
Granted: 1905-09-28
Abstract: 25,730. British Thomson-Houston Co., [General Electric Co.]. Nov. 25. Armatures; brushholders; field magnets ; motors, controlling.-Dynamo-electric machines of the homopolar type having series characteristics, and more particularly high-speed motors, are rendered self-exciting by the employment of auxiliary conductors h, Figs. 1 and 2, connected between the brushes B and the stationary return or frame conductors f. The field F is unwound, but may be provided with an exciting coil, if desired. The armature conductors a, preferably made in flat strips, are held in place by a cylindrical binding ring b, and are connected at each end to collecting-rings C. The collecting-brushes B are mounted on bars D carried by adjustable rings E, which may be rotated to shift the brushes. The return conductors fare joined to brushes B displaced therefrom a fraction of the circumference by means of flexible connections h. The current in the conductors f is equal and opposite to that flowing in the armature, thereby neutralizing armature reaction. The several flexible connections h form together one or more complete turns carrying a current which produces a flux passing round the field frame through the armature and across the air gap where it is cut by the armature conductors. The motor may be controlled by shifting the brushes in one direction or the other to vary the effective length of each flexible conductor and consequently the field excitation.
