Eikronometer

1894

R. Field & Co.

Birmingham

England

Image of Eikronometer

2" dial. Single hand with pointer attached to the inside of the movable glass. One sweep of the hand is ten minutes. Movement by British United Clock Co.

This is a darkroom clock combined with a slide rule to show the development time using the Watkins Factorial method. The time taken for the image to appear is set on one of the brass dials at the end of the clock, a pointer then indicates the complete development time, the glass dial is moved so that a small hand indicates this time, the clock hand is then re-set and the clock started. The Eikronometer was shown at the 1894 RPS exhibition. There are minor variations, the example shown here is probably an early model. See Factorial Development. for details.

BP 23894/1893 (The patent covers different ways to time plate development one of which was by using a clock coupled with a slide rule.).
