Abstract
Abstract An indexing mechanism particularly adapted to drive a turntable in a solid waste compactor system includes a central rotating hub mounting the turntable and carrying a series of drive pins. A drive plate is pivotally mounted adjacent the hub and includes a drive pawl for rotating the hub. The system may be adjusted to assume a selected number of indexing positions in each 360* rotation to accommodate turntables having different numbers of refuse receptical positions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A turntable indexing system adaptable to assume a selected number of indexing positions in each 360* rotation comprising a turntable supported for rotational motion about a central axis, a support hub removably secured on a common center with said turntable for rigid rotation therewith, said support hub including a selected number of drive pins positioned equidistantly about said hub, said pins corresponding with the desired number of indexing positions of said turntable in each 360* rotation, a drive plate mounted for oscillation about said hub, power means for oscillating said drive plate between a retracted position and a forward indexed position, a driving pawl on said drive plate adapted to engage one of said drive pins when said drive plate is in its retracted position and to rotate said hub during the forward power stroke of said drive plate, and switching means controlling said power means for determinging the length of the stroke of said drive plate.
Claim 2
Dependent Claim
157 words
A turntable indexing system adaptable to assume a selected number of indexing positions in each 360* rotation comprising a turntable supported for rotational motion about a central axis, a support hub removably secured on a common center with said turntable for rigid rotation therewith, said support hub including a selected number of drive pins positioned equidistantly about said hub, said pins corresponding with the desired number of indexing positions of said turntable in each 360* rotation, a drive plate mounted for oscillation about said hub, power means for oscillating said drive plate between a retracted position and a forward indexed position, a driving pawl on said drive plate adapted to engage one of said drive pins when said drive plate is in its retracted position and to rotate said hub during the forward power stroke of said drive plate, and switching means controlling said power means for determinging the length of the stroke of said drive plate.
Claim 3
Dependent Claim
48 words
Apparatus in accordance with claim 1 further including a stop pawl positioned in opposition to said driving pawl, said stop pawl being driven into engagement with one of said pins at the end of the power stroke of said drive plate for providing a stop for said turntable.
Claim 4
Dependent Claim
50 words
Apparatus in accordance with claim 2 wherein said stop pawl includes a spring biasing it radially outwardly and wherein said drive plate includes means adapted to engage said stop pawl at the end of said power stroke to drive said stop pawl into engagement with one of said drive pins.
Claim 5
Dependent Claim
52 words
Apparatus in accordance with claim 1 wherein said switching means includes a switch controlling said power means mounted adjacent said drive plate and control means on said drive plate for actuating said switch, the position of said control means being adjustable to regulate the length of the stroke of said power Plate.
