SELF-RECORDING 

 ATWOOD MACHINE 



Made by G. CUSSONS 



Accurate results may be obtained and dupli- 

 cated ■with this new Atwood Machine, without 

 long and careful experimenting. It operates 

 automatically, without the necessity of the ear, 

 eye and hand working in unison ; and there is 

 no hysteresis lag, as is so often found when 

 electrical devices are used. The record is made 

 on a long narrow strip of paper. It is very 

 clear and easily interpreted. 



The Cussons Self-Recording Atwood 

 Machine is a very distinct improvement over 

 the older forms. It is very rugged in construc- 

 tion and moderate in cost.
