Description (US Patent, "Camera", Inventor: George Lipshitz, Publication Number: US1849939 A):
This invention relates to cameras and particularly to means for producing a photographic record of the exact time of the occurrence of an event taken by the camera.
One object of the invention is to provide means for producing a visible record of the time of the start and finish of a sporting event such as a horse race or the like.
At some sporting events a visible starting signal is provided for operation simultaneously with an audible signal, therefore another object of the invention is to provide means for obtaining, with a photographic record of the visible starting signal, a photographic record of the exact time of the commencement of the race.
It follows that with a photograph of the starting time of an event, such as a race, and with a photograph of the finishing time of the race, an indisputable time record of the event is available, including the exact time consumed by the race.
A feature of the invention is a novel watch comprising a relatively small case containing the usual mechanism, and a large fixedly associated frame within which the hands move, and on the transparent face of which the usual numerals are arranged. The numerals on the dial are outside of the peripheral boundary of the case containing the mechanism, and are therefore available for being photographed on t-he negative, with the subject, since said dial and said case are installed within a camera.
