TRANSFORMER.
(App! t man 23 1898) (No Model.)
UNITED STATES PATENT OFFICE.
ENGELBERT ARNOLD, OF CARLSRUI-IE, GERMANY.
TRANSFORMER.
SPECIFICATION forming part of Letters Patent No. 644,565, dated March 6, 1900.
Application filed December 23, 1898. Serial No. 700,164. (No model.)
To ctZZ whom, it may concern:
Be it known that I, ENGELBERT ARNOLD, a subject of the Emperorof Germany, and a resident of Oarlsruhe, Germany, have invented certain new and useful Improvements in R0- tating-CurrentTransformers, of which the following is a specification.
This invention relates to the construction of a, transformer of rotating currents. The
novel construction differs from the arrangements which are already known in that it enables the transformer to perform a given amount of work with a minimum of weight of the iron,while avoiding the losses which might I 5 otherwise be caused by the joints.
The improved transformer is represented in Figures 1, 1, 2, and 2'" of the accompanying drawings.
It consists of three cores K K K, made up of pieces of sheet-iron, which in the plan Fig. 1
are supposed to be circular. For the purpose of closing the magnetic circuits the cores are connected by a yoke in three sections J J J at their ends. The connection of the yoke yoke, as shown in Figs. 2 and 2, where the portions of the yoke are marked with thick lines and the parts of core in fainter line. It is in the division of the yoke into three sections and in the manner of arranging the three parts that the principle of the invention mainly resides. The advantages afforded by this division of the yoke into three parts will be best understood by comparing the novel construction with the apparatus previously known.
Having now particularly described and as certained the nature of this invention and in what manner the same is to be performed, I declare that what I claim is- A transformer of rotating currents having three iron cores connected by a yoke in three sections, the ends of two sections of the yoke being magnetically connected to each core, and two cores being connected by each section, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ENGELBERT ARNOLD.
Witnesses:
OTTO JAHNEET, HUGO ROGGEN.
