A Hipp Chronoscope, late 19th, early 20th century, signed on the lower silvered dial by engraved script, “Payer Favarger & Cie, Neuchatel Suisse No 20658 . The wooden base is stamped “PS 276 . The instrument stands 22 tall and consists of rosewood platforms with pear and ebonized columns. Four electrical terminals sit on the lower platform. The weight-driven clockwork movement sits upon the upper platform with the weight drive suspended from the center of the movement.
The movement is also marked on the top of the back plate, “20658”, matching that of the serial numbers engraved on the silvered dial. The movement is further stamped with batch numbers “58 . Two arms used to activate the timer, are fit with string and turned ivory acorns. This is the improved version of the Hipp Chronoscope (four coils). Each set of has separate adjustment levers, each with graduated silvered arcs, used to adjust the spring tension on the steel plates. The movement is free and functional but certainly in need of proper lubrication and adjustment to be brought up to its designed accuracy.
The condition of the instrument is very good. It retains most of its original finish and lacquer; there is minor discoloration on some of the blued screws. The weight shown is not the correct weight; the original weight was wider and not as tall.
The base markings “PS 276” suggest this was once used in a psychology department. Possibly, with further research, these numbers could link provenance to an institution. This is a very uncommon and accurate timer, used to document human reaction time. It is one-of very few Hipp Chronoscopes in private hands.
