Figure 30: Löbner chronoscope, private collection, with special unit for measuring the times of the electromagnet I know of two “type 1” chronoscopes. Both instruments are signed “F. L. Löbner, Berlin.” They are very similar to “model 257” made by Peyer, Favarger & Cie. Both instruments have a running time of six minutes, no serial number and the special device for the electromagnet. The other type seems to be more recent and probably was made around 1925: Figure 31: Löbner Chronoscope, more recent type (Kaltenbach, 1938) [95] 36
Strasser & Rohde, Glashütte The case of this firm shows similar patterns. Strasser & Rohde in Glashütte was a well known manufacturer of high precision clocks and instruments. It is evident that Strasser & Rohde have produced their own chronoscopes during the 1930s. Their chronoscope was based on Hipp’s, but it was of their own construction. The differences are visible: Figure 32: Chronoscope made by Strasser & Rohde The Strasser & Rohde chronoscope is very similar to the more recent Löbner type shown above. A discovery of high importance was a wooden box coming from the workshop of Strasser & Rohde. In this box we have found an unfinished chronoscope, special tools, three unused dials, some Hipp lamellas and escape wheels, one complete unit for the fine adjustment of the electromagnets, wooden bodies for the coils, a winding key and other parts in little paper bags and boxes. Figure 33: Strasse & Rohde box with chronoscope parts (private collection) This chronoscope has a running time of 6 min. It has the same additional device for the electromagnets as the Löbner chronoscope. Hans Jochen Kummer and I have examined this movement and the movement of a Löbner chronoscope very carefully. 37
