Abstract
Abstract A by-pass mechanism for a conveyor system which enables a series of articles to be diverted from the main conveying path. The conveyor system includes a main conveyor section for conveying a series of cans or other articles and a by-pass conveyor section which is connected to the main conveyor section. An inverted Ushaped gate is pivotally connected to the side of the main conveyor section and is pivotable between a conveying position, in which it is in alignment with the main conveyor section, and a bypass position in which it serves to divert articles through the by-pass conveyor section. The gate is pivoted by a fluid cylinder mounted on the side of the conveyor and by manual actuation of the cylinder, the gate can be pivoted to the bypass condition which enables a series of the articles to be diverted to the bypass conveyor section for purposes of inspection.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
249 words
In a conveyor system, a conveyor, a first guide member located above the conveyor, a second guide member located above the conveyor and disposed in spaced relation to said first guide member with the space between said first and second guide members defining a conveying path for movement of articles on said conveyor, said second guide member having an opening, a gate mounted on the conveyor and located adjacent the opening, said gate including a pair of spaced side walls defining a passage therebetween and having a cross member rigidly connected between said side walls, pivotal means for pivotally connecting the gate to the conveyor adjacent said first guide member whereby the entire gate can be pivoted between a first position, in which the passage is aligned with said conveying path, to a second position in which said passage is aligned with the opening in said second guide member whereby articles passing along said path are diverted through said passage to said opening, the length of the side wall of the gate is less than the length of the opening in said second guide member to provide a gap between an end of said gate and the edge of said second guide member bordering said opening when said gate is in the first position, and a flexible baffle member extending across the said gap and disposed to flex when the gate is moved to said second position, and means for moving the gate between said first and second positions.
Claim 2
Dependent Claim
249 words
In a conveyor system, a conveyor, a first guide member located above the conveyor, a second guide member located above the conveyor and disposed in spaced relation to said first guide member with the space between said first and second guide members defining a conveying path for movement of articles on said conveyor, said second guide member having an opening, a gate mounted on the conveyor and located adjacent the opening, said gate including a pair of spaced side walls defining a passage therebetween and having a cross member rigidly connected between said side walls, pivotal means for pivotally connecting the gate to the conveyor adjacent said first guide member whereby the entire gate can be pivoted between a first position, in which the passage is aligned with said conveying path, to a second position in which said passage is aligned with the opening in said second guide member whereby articles passing along said path are diverted through said passage to said opening, the length of the side wall of the gate is less than the length of the opening in said second guide member to provide a gap between an end of said gate and the edge of said second guide member bordering said opening when said gate is in the first position, and a flexible baffle member extending across the said gap and disposed to flex when the gate is moved to said second position, and means for moving the gate between said first and second positions.
Claim 3
Dependent Claim
32 words
The conveying system of claim 1, including a low friction coating applied to the inner surface of said side walls of the gate to faciliate movement of said articles through said passage.
Claim 4
Dependent Claim
39 words
The conveying system of claim 1, wherein said baffle member connected to the gate and is curved laterally outward and disposed to ride against said second guide member as the gate is pivoted between said first and second positions.
Claim 5
Dependent Claim
42 words
The conveying system of claim 1, and including a second conveying path communicating with said opening, and said system includes a divider member located between said first and second conveying paths, said divider member having a tapered tip facing toward said gate.
Claim 6
Dependent Claim
29 words
The conveyor system of claim 4, and including means for adjusting the position of said tapered tip in a direction longitudinal of the direction of movement of said conveyor.
Claim 7
Dependent Claim
29 words
The conveyor system of claim 4, and including means for adjusting the position of said tapered tip in a direction transverse of the direction of movement of said conveyor.
Claim 8
Dependent Claim
192 words
In a conveyor system, a conveyor for conveying articles, guide means for guiding articles in movement on said conveyor, a by-pass area disposed to receive articles diverted from said conveyor, said guide means having an opening communicating with said by-pass area, a gate located above said conveyor and having a pair of spaced side members defining a passage, said gate being mounted for movement between a first position in which said passage is disposed in alignment with said conveyor and one of said members partially closes off said opening in said guide means and a portion of said opening is exposed, to a second position in which said passage is disposed in alignment with said opening whereby articles will be conveyed from said conveyor through said passage to said by-pass area, means for moving said gate between said first and second positions, and flexible closure means for closing the exposed portion of said opening when the gate is in the first position, said closure means is a flexible strip mounted on the gate and disposed to ride against the guide means as the gate is moved between the first and second positions.
Claim 9
Dependent Claim
192 words
In a conveyor system, a conveyor for conveying articles, guide means for guiding articles in movement on said conveyor, a by-pass area disposed to receive articles diverted from said conveyor, said guide means having an opening communicating with said by-pass area, a gate located above said conveyor and having a pair of spaced side members defining a passage, said gate being mounted for movement between a first position in which said passage is disposed in alignment with said conveyor and one of said members partially closes off said opening in said guide means and a portion of said opening is exposed, to a second position in which said passage is disposed in alignment with said opening whereby articles will be conveyed from said conveyor through said passage to said by-pass area, means for moving said gate between said first and second positions, and flexible closure means for closing the exposed portion of said opening when the gate is in the first position, said closure means is a flexible strip mounted on the gate and disposed to ride against the guide means as the gate is moved between the first and second positions.
