357. Printing Beam for Weighing Machine, admitting of 



the registration of each weighing. M. Chameroy, Paris. 



This method of checking is applicable to all weighing machines in the 

 nature of the steel-yard. It would be found useful at custom houses, depots, 

 markets, railway stations, works, and other similar places. 



Its advantages are : 



1. The affording of a record, by means of a printed impression on a special 

 ticket, of the exact amount of the weight as determined by the machine itself. 



2. The facilitating of the reading of the weights, either on the ticket or on 

 the scale beam. 



3. The preservation of an exact record" of weighings, the authenticity of 

 which is thus ensured.
