Abstract
An indexing device for indexing a member, such as a table, into operative working positions in which the table carries follower elements, such as rollers, and cooperating therewith is a drive member mounted on a pair of parallel equal length arms which rotate in unison thereby causing the drive member to take an orbital path. The drive member is slotted and during travel along the orbital path picks up one of the followers on the table and therethrough causes the table to carry out an indexing movement. The indexing movement of the table is smooth and does not involve movement of the table at excessive speeds.
Claims5
In combination;
- a rotary table and an indexing device therefor, said table having follower elements thereon in circumferentially distributed relation, a drive block adjacent the table having a slot therein for receiving a follower and movable for engaging a said follower, and actuating means connected to said block and operable for moving said drive block bodily in an orbital path without rotation during which said slot in the drive block engages a follower and moves it and the table in one direction a distance equal to the spacing between said followers and then releases the follower from the slot.
