When the conveyor is in operation the weigh-ing machine automatically takes a weight every time the conveyortravels the suspended distance, and as the weight of the trackand empty buckets is balanced oft, only the aggregate net weightof the coal Is recorded on the indicator. The machine is drivenby the conveyor itself and therefore any change in the speed ofthe conveyor means a corresponding change in the frequency ofthe weighings. Undue oscillation of the beam, which would other-wise be caused by change of load, is avoided by a patented mer-cury dashpot. The manner in which the height of the beam is transformedinto figures upon a record is as follows:— The beam takes a position according to the weight on thescale platform. It is then gripped and held in that positionwhile a curved quadrant moves to the right until it comes intocontact with tlir Ill- higher tlio when gripped the.

The quadrant is thenmoved back to its normal position, carrying a ratchet wheel withit; this ratchet wheel turns on its axis a distance proportionateto the height of the beam. The beam is then released and takesa new position in accordance with the weight of the coal in thenext two buckets. This machine, which is being introduced by the Weston Engi-neering Company, of New York, is one of the features of the newelectric power station of the New Jersey Public Service Corpora-tion at Marion.
