Abstract

Abstract A work indexing apparatus is provided having a plurality of platens mounted on an endless conveyor adapted to be moved to a plurality of work stations in an indexing mode. The platens are positioned precisely by means of pins having a tapered surface rigidly attached to the platens and sockets adapted to receive the platens. The sockets are movable in an arcuate path to receive the pins and are linked to a common actuating means.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 153 words
A work indexing apparatus including a table, an endless conveyor means adjacent said table, a plurality of spaced platen means attached to said conveyor in slidable contact with said table along at least a portion of the path of travel of said conveyor means, driving means for said conveyor means to move said conveyor means and platen means incrementally along said path, and positioning means for said platen means, said positioning means comprising at least two pins having a tapered surface rigidly attached to a surface of each of said platen means, a plurality of socket means mounted on at least one common rotatable shaft wherein a socket means is associated with each of said pins on at least one of said platen means for moving in an arcuate path to receive said pins on at least two of said platen means in order to precisely position the platens adjacent said socket means.
Claim 2
Dependent Claim 153 words
A work indexing apparatus including a table, an endless conveyor means adjacent said table, a plurality of spaced platen means attached to said conveyor in slidable contact with said table along at least a portion of the path of travel of said conveyor means, driving means for said conveyor means to move said conveyor means and platen means incrementally along said path, and positioning means for said platen means, said positioning means comprising at least two pins having a tapered surface rigidly attached to a surface of each of said platen means, a plurality of socket means mounted on at least one common rotatable shaft wherein a socket means is associated with each of said pins on at least one of said platen means for moving in an arcuate path to receive said pins on at least two of said platen means in order to precisely position the platens adjacent said socket means.
Claim 3
Dependent Claim 22 words
The apparatus of claim 1 wherein the conveyor means is adapted to move in a closed path in a generally horizontal plane.
Claim 4
Dependent Claim 22 words
The apparatus of claim 1 wherein the conveyor means is adapted to move in a closed path in a generally vertical plane.
Claim 5
Dependent Claim 21 words
The apparatus of claim 1 having two rotatable shafts, each of said shafts having a plurality of socket means mounted thereon.
Claim 6
Dependent Claim 101 words
A positioning apparatus for a plurality of spaced platen means adapted to move incrementally in a closed path comprising at least two pins having a tapered surface rigidly attached to a surface of each of said platen means, a plurality of pairs of rigidly spaced arms each having sockets to receive said pins in order to precisely position the platen means, a plurality of pairs of said arms being mounted on at least one common rotatable shaft, and a single actuating means for rotating all of the said common rotatable shafts in order to move said sockets in an arcuate path.
Claim 7
Dependent Claim 101 words
A positioning apparatus for a plurality of spaced platen means adapted to move incrementally in a closed path comprising at least two pins having a tapered surface rigidly attached to a surface of each of said platen means, a plurality of pairs of rigidly spaced arms each having sockets to receive said pins in order to precisely position the platen means, a plurality of pairs of said arms being mounted on at least one common rotatable shaft, and a single actuating means for rotating all of the said common rotatable shafts in order to move said sockets in an arcuate path.
Claim 8
Dependent Claim 22 words
The apparatus of claim 5 having two common rotatable shafts each having mounted thereon a plurality of pairs of rigidly spaced arms.
