A BIT OF INTERESTING HISTORY OF THESE SCALES

Roberval Scales
The Roberval Balance is a weighing instrument which is named after its inventor Gilles de Roberval, French mathematician and physicist,born in 1602
Gilles had the ingenious idea of placing the trays above the beam, while they traditionally were suspended below the beam. Roberval scales were first made ​​in England under the name "French balances." Their manufacture in France is just beginning in the early 19th century, when the Continental Blockade, as the "English scales." Production becomes important after 1850 and will remain dominant until the late 1980s, with models that are suited to different activities: the principle of Roberval gives good accuracy in weighing, good stability in the setting and strength the test of time.

The largest scale manufacturers were Roberval W. & T. Avery Ltd. and George Salter & Co. Ltd.UK and Trayvou in France.

Two events have marked the history of Roberval scales: about 1850 Joseph Beranger native of Saone-et-Loire and founder of the company that later became Trayvou Roberval improves the system by adding subsidiary evils instead of reducing vertical rods and lateral forces and thereby the friction on the knives. Then in the 1980s, the arrival of electronic scales sensing charges gradually put an end to large-scale production of Roberval balances.

..."The object to be weighed is placed on one pan, and standard weights are added to the other until the balance of the beam is established again. The unknown weight can then be determined by adding up the standard weights in the pan.Equal arm scales and balances were made for many different usage such as weighing money, gold silver and diamonds, grocery, postal parcels, chemicals etc. The details of each scale were modified and adapted to its specific use. These adaptations involved inventing new ideas that changed the classical form of Equal Arm beam. An example of such modification is the Roberval Scales: In order to place the scales on a table and lessen the friction, a mathematician called M. Gilles de Roberval invented in 1730 scales with two main beams and load platforms located on top of the beams, one at each end. These scales had two central hinges, which lessened the stress on the main hinge by half, and the precision grew immensely. Manufacturing Roberval scales with the pans above the beam started only at the beginning of the 19th century. This development allowed the scales to be placed on a table or shelf and therefore simplify the weighing process. These types of scales caught on very fast and were soon seen in market stalls and post offices...."
