Description: |
| "This instrument is constructed with a suspension stem and beam connected by rods extending down through a case of cylindrical or other form to a load-beam. The load is applied preferably to a stem swiveled in a pair of cross-heads, between which is interposed a buffer-spring. Said cross-heads are connected to the case by fixing-studs. The load is transmitted from the case to a pressure-column on the load-beam of the suspension-yoke through the medium of the fulcrum attachments of a load-lever connected by one or more secondary levers with a resisting-spring to take up the pressure and a rotary indicator to show the extent and value of the deflection of the levers produced by the load..." |
