The Edison Electric Illuminating Company of Boston tried out the master clock on October 23, 1916. Since then this regulation has continued. Other power companies adopted Warren’s master clock. Today virtually all alternating current furnished in America is similarly checked. Practical electric time is available at the light socket almost everywhere. But there are additional benefits. Standardizing the frequency expanded the market for current to run the increasing number of clocks in use. Yet, from the consumer’s point of view, each clock draws little current, costing but a few pennies a month. Uniform frequency also gave more even speeds in motor-driven machinery, with a resultant improvement in product. It made easier the joining of one power station to another. Synchronous motors used in certain meters and recorders produced better, more accurate records at lower cost. The Warren enterprise expanded rapidly. The battery clock was discontinued. The red barn was no longer large enough, and new space was acquired. The trade mark “Telechron,” meaning “time from a distance” (from two Greek words), was used to identify all products of the company. The firm name was changed to stress the name Telechron, and in 1952 a merger was made with the General Electric Company. Plants are now operated in Worcester as well as in Ashland, Massachusetts. And now back to the telegraph field.... CHAPTER 4 Morkrum-Kleinschmidt Corporation (later renamed “Teletype Corporation”) During and after the first world war, both the Morkrum Company and the Kleinschmidt Electric Company were progressively developing and producing telegraph apparatus and bringing out new and improved operating devices to a point where conflicting patents were at issue. This meant infringement litigation which might destroy both companies. Neither company could obtain orders in sufficient quantity to make the manufacturing of apparatus profitable, and, with costly development work at hand, more capital investment was a continuous requirement. The following excerpts from the March 1932 issue of _Fortune_[9] tells of the final joining of the two companies.
