RHEOPECTIC GREASE Available to Purchase

A Rheopectic Grease is one that solidifies upon flowing, or at least that is its meaning expressed practically. The advantages of such a grease are mainly concerned with its use in mechanical lubricators, because they can be easily pumped and yet will not drip when they reach the bearing. Greases have the disadvantage that they may be difficult to pump and may not easily flow through restricted passages in the pump. It is in view of the possibility of fitting chassis lubricators to motor cars in the future that a study of rheopectic greases may prove timely. The subject has been reviewed by Neesley, Brunstrum and Liehe (all of the Research Department, Standard Oil Company, Indiana), in a paper to the S.A.E. at Atlantic City in June. The American chassis lubricator, the Multi‐Luber (described in our August issue) was partly responsible for this work, and the authors describe how this new lubricant functions in this unit.
