In a former paper the author made an experimental determination of the elastic properties of crystals of Rochelle salt or Potassium Seignette salt, a double tartrate of sodium and potassium with the formula Na. K. C 4 H 4 O 6 4H 2 O. Ammonium Seignette salt (NaNH 4 C 4 H 4 O 6 4H 2 O) belongs to the same isomorphous group, and can be obtained in large crystals. It was thought that some interesting results should be obtained on determining the elastic properties of this latter salt, where the ammonium group merely replaces the potassium atom. A comparison of the two results should give some indication of the physical effect due to these chemical changes in the complex molecule.

An experimental study was conducted to determine the effect of elastic properties, geometric variations, and lubrication on roller chain load distribution. Comparison was made with the theoretical results for a test chain on a 20-tooth sprocket. The load distribution was found for a large number of cases to be independent of the elastic properties of the chain and the sprocket. The load distribution for the chain on a driver sprocket differed from that for a chain on a driven sprocket because of the change in direction of the friction force. Lubrication had no noticeable effect. A large pitch for the sprocket teeth was found to amplify the tension in the chain link.
