Abstract
Abstract A conveying system having particular use for a stamping press. One or more endless belt conveyors are located in the space beneath the die shoe and the bolster plate of the stamping press, and the stamped parts falling from the die cavity are collected on the conveyors. Each conveyor includes an endless belt which is supported at its ends by a pair of spindles, and at least one of the spindles is provided with a non-circular bore. A drive shaft extends through the aligned bores in the spindles of the series of conveyors, and rotation of the shaft acts to drive the conveyors in synchronization. A provision is made to tighten each belt by utilizing a series of staggered pins which extend transversely of the belt. By training the belt over one or more of the staggered pins the desired degree of tension can be maintained on the belt.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
198 words
A conveyor system, comprising a series of endless belt conveyors disposed in side-by-side relation, each conveyor having a pair of spaced side walls and including a drive spindle and an idler spindle and an endless belt trained over the drive spindle and the idler spindle, the ends of the spindles disposed inwardly of the respective side walls, each drive spindle having a noncircular bore and the bores of the spindles being disposed in axial alignment, a drive shaft disposed within the aligned bores of the spindles and having a non-circular peripheral surface to complement the bores, each end of the drive spindle being provided with an axial recess, a bushing secured within an aperture in the side wall and received within the recess in the corresponding end of the spindle, whereby the ends of the spindle are journalled on the respective bushings each bushing having a central opening to receive the shaft with the diameter of the central opening being greater than the external dimension of the shaft so that the shaft is out of contact with the bushing, and drive means operatively connected to the shaft to drive the shaft and simultaneously operate the series of conveyors.
Claim 2
Dependent Claim
198 words
A conveyor system, comprising a series of endless belt conveyors disposed in side-by-side relation, each conveyor having a pair of spaced side walls and including a drive spindle and an idler spindle and an endless belt trained over the drive spindle and the idler spindle, the ends of the spindles disposed inwardly of the respective side walls, each drive spindle having a noncircular bore and the bores of the spindles being disposed in axial alignment, a drive shaft disposed within the aligned bores of the spindles and having a non-circular peripheral surface to complement the bores, each end of the drive spindle being provided with an axial recess, a bushing secured within an aperture in the side wall and received within the recess in the corresponding end of the spindle, whereby the ends of the spindle are journalled on the respective bushings each bushing having a central opening to receive the shaft with the diameter of the central opening being greater than the external dimension of the shaft so that the shaft is out of contact with the bushing, and drive means operatively connected to the shaft to drive the shaft and simultaneously operate the series of conveyors.
Claim 3
Dependent Claim
39 words
The conveying system of claim 1, wherein the outer end of each bushing is disposed substantially flush with the outer surface of the respective side wall, and said system includes means for locking each bushing within the respective aperture.
Claim 4
Dependent Claim
56 words
The conveyor system of claim 1, wherein said system includes a plurality of guide members extending between the side walls and disposed in staggered relation, means for removably connecting the guide members to the side walls, said belt being trained around a series of the staggered guide members to provide the desired tension on the belt.
Claim 5
Dependent Claim
44 words
The conveying system of claim 3 and including locking means for locking each guide member with respect to the side walls, each guide member and the corresponding guide member being located wholly within the plane of the outer surface of the respective side wall.
Claim 6
Dependent Claim
29 words
The conveying system of claim 4 wherein each guide member includes a pin fixed in position with respect to said side walls, and a sleeve journalled on said pin.
Claim 7
Dependent Claim
71 words
The conveying system of claim 2, wherein the means for locking each bushing comprises a keeper having a first portion disposed within a slot in the outer end of the bushing and having a second portion extending through an opening in the side wall and secured to the inner surface of said side wall, said keeper being located wholly within the plane of the outer surface of the respective side wall.
Claim 8
Dependent Claim
240 words
A conveyor system, comprising a series of endless Belt conveyors disposed in side-by-side relation, each conveyor having a pair of spaced side walls and including a drive spindle and an idler spindle and an endless belt trained over the drive spindle and the idler spindle, the ends of the spindle disposed inwardly of the respective side walls, each drive spindle having a non-circular bore and the bores of the spindles being disposed in axial alignment, a drive shaft disposed within the aligned bores of the spindles and having a non-circular peripheral surface to complement the bores, each end of the drive spindle being provided with an axial recess, a bushing secured within an aperture in the side wall and received within the recess in the corresponding end of the spindle, whereby the ends of the spindle are journalled on the respective bushings, each bushing having a central opening to receive the shaft with the diameter of the central opening being greater than the external dimension of the shaft so that the shaft is out of contact with the bushing, drive means operably connected to the shaft to drive the shaft and simultaneously operate the series of conveyors, and a locking member for locking each bushing within the respective aperture, each bushing and the corresponding locking member being located wholly within the plane of the outer surface of the respective side wall whereby the conveyor is free of laterally extending projections.
Claim 9
