A further object of the invention is to devise a novel construction of a ring which can be economically manufactured, and which will be accurate and reliable in use.
A further object is to devise a ring which can be used under tension or compression.
With the foregoing and other objects in view as will hereinafter clearly appear, my invention comprehends a novel ring for use as a weighing system or for Calibrating a weighing system.
For the purpose of illustrating the invention, I have shown in the accompanying drawings a preferred embodiment of it which I have found in practice to give satisfactory and reliable results. It is, however, to be understood that the construction illustrated -is susceptible of modification within the scope of the appended claims.
Figure 1 is a front elevation of a proving ring, embodying my invention.
Figure 2 is a section on line 2--2 of Figure l.
