device for achieving coordinated movements of a number of active components.

摘要

Plural refuse receivers on an indexable support are positioned in succession below the outlet of a refuse delivery chute. A refuse compacting member is held in a neutral position between two adjacent receivers while refuse is being delivered into each receiver from the chute. During the indexing of the support carrying the refuse receivers and while the support is at a dwell, the compacting member is driven downwardly to act on refuse in one receiver and is then elevated above the receivers prior to the next indexing, all by the operation of a simplified power-operated movement programming mechanism.
