Patent number: 5608516Abstract: A machine for inspecting a glass bottle comprising a bottle supporting track, a car for conveying a bottle along the track to a bottle inspection station. The car includes rollers for rotatably engaging one side of the bottle and a wall mechanism forcefully engages the other side of the bottle as it is conveyed to the bottle inspection station. The wall mechanism includes a pivotally displaceable support, which is biased towards a fully advanced position. Linear bumpers secured to the support extend into the path of a conveyed bottle when the support is at the fully advanced position so that a bottle will engage the linear bumpers and forcefully pivotally displace the support to a retracted position as the bottle is conveyed to the inspection station. The length of the linear bumpers is selected so that when a bottle is conveyed to the inspection station, the bottle will be conveyed past the linear bumpers whereby the support will be displaced back to the fully advanced position.Type: GrantFiled: December 13, 1995Date of Patent: March 4, 1997Assignee: Emhart Glass Machinery Investments Inc.Inventor: Monti D. Emery
