Abstract
Abstract Apparatus to slow articles in a stable manner as they exit from an inspection device in which the articles are precessed out of the inspection device by means of a continuously moving, sideengaging belt and a fixed rail. At the exit of the article inspection device, a pulley is driven by the belt which is used to move the articles through the device. The pulley is mounted on the outer ring of a rolling element bearing which has its rolling elements restrained within a vertically elongated cage. A deceleration disc having a radius larger than the pulley is driven by the elongated cage. Due to the difference in radii of the outer ring and the cage, the pulley will rotate faster than the deceleration disc. Thus, as articles are brought into contact with the deceleration disc as they exit the inspection device, they will be slowed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
In an apparatus for inspecting articles having a horizontal main conveyor for supporting articles in upright position and carrying them in succession past an article testing station provided near one side at said main conveyor, with a generally horizontal floor having inlet and exit ends at one side at said main conveyor, with an inspection station located between said ends, with means for rotatively holding articles upright one-ata-time at said inspection station, and with a continuously driven endless belt for both advancing articles in succession along said floor to and from said inspection station and rotating them while being held at said inspection station, the improvement comprising: Rotating article deceleration means driven by said continuously driven endless belt at a speed less than the speed of said articles and mounted at the exit end of said horizontal floor in the path of travel of said articles for reducing the speed of said articles to return said articles from said floor to said main conveyor without overturning said articles as a result of engagement of said articles by said rotating article deceleration means.
Claim 2
Dependent Claim
182 words
In an apparatus for inspecting articles having a horizontal main conveyor for supporting articles in upright position and carrying them in succession past an article testing station provided near one side at said main conveyor, with a generally horizontal floor having inlet and exit ends at one side at said main conveyor, with an inspection station located between said ends, with means for rotatively holding articles upright one-ata-time at said inspection station, and with a continuously driven endless belt for both advancing articles in succession along said floor to and from said inspection station and rotating them while being held at said inspection station, the improvement comprising: Rotating article deceleration means driven by said continuously driven endless belt at a speed less than the speed of said articles and mounted at the exit end of said horizontal floor in the path of travel of said articles for reducing the speed of said articles to return said articles from said floor to said main conveyor without overturning said articles as a result of engagement of said articles by said rotating article deceleration means.
Claim 3
Dependent Claim
126 words
The improvement of claim 1, wherein said article deceleration means comprises: a. A stationary vertical shaft adjacent the exit end of said horizontal floor; b. a rolling element bearing having inner and outer rings connected by a plurality of rolling elements, said inner ring being fixedly attached to said vertical shaft, said outer ring being free to rotate relative to said inner ring through said rolling elements; c. a driven member, carried by said outer ring, in engagement with said continuously driven endless belt; d. an elongated cage drivingly connected to said rolling elements; and e. a deceleration disc rotatably mounted on said vertical shaft and drivingly connected to said vertical cage, said deceleration disc having a radius greater than the radius of said driven member.
Claim 4
Dependent Claim
18 words
The apparatus of claim 2, wherein the periphery of said deceleration disc is covered with an elastomeric material.
Claim 5
Dependent Claim
124 words
The apparatus of claim 2, further including a. A second rolling element bearing having inner and outer rings connected by a plurality of rolling elements, said inner ring being fixedly attached to said vertical shaft below said first rolling element bearing, said second rolling element bearing outer ring being attached to said driven member and being free to rotate relative to said inner ring through said rolling elements, said cage extending vertically downward and drivingly connected to said rolling elements of said second rolling element bearing; and b. a second deceleration disc rotatably mounted on said vertical shaft below said second rolling element bearing and drivingly connected to said cage, said deceleration disc having a radius greater than the radius of said driven member.
Claim 6
Dependent Claim
19 words
The apparatus of claim 4, wherein the periphery of said second deceleration disc is covered with an elastomeric material.
