Description: |
| Claim:
The invention consists in certain improved mechanism in planimeters, whereby a special adaptation of previously-known instruments is secured to integrate meter-charts of an elongated or continuous pattern which are produced from a meter from which the volume of steam or other fluid consumption is graphically registered. This adaptation of the instrument comprises improvements in its construction which will facilitate and extend its capacity for measuring and indicating the superficial contents of such charts, and for ascertaining the mean heights of the diagrams thereon. |
