Natograph Poster

Item Information

Title:
Natograph Poster
Description:
This poster was created by the Springfield College Department of Physiology and features their experiments with the natograph, a machine invented by Peter V. Karpovich. The photograph on the left shows the natograph and the one on the right shows the machine in use in Judd Gymnasium. Between the two photographs are tracings reproduced from the natograph detailing five different swimming strokes. For more information on Peter V. Karpovich, see: https://springfield.as.atlas-sys.com/agents/people/571 The natograph tested the efficiency of swimming strokes by measuring the progression of a swimmer every one fifth of a second. It consisted of a revolving drum around which a line was fastened and attached to the swimmer’s waist (as seen in the framed diagram) or to a floating tripod over the swimmer, and a revolving contact switch to mark time intervals on a kymograph (a rotating drum holding paper on which a stylus traces a continuous record). As the line was pulled by the swimmer it revolved the drum. Edges have tears and the left photograph is not attached; Originally digitized in 2009 for an exhibit. That digital copy did not represent the whole document. This is the second time this document has been digitized;
