Clark Weber, 53, of Ross, was killed early Saturday when he got caught in a conveyer belt at the Glenshaw Glass facility on William Flynn Highway, according to the Allegheny County Coroner's Office.
An autopsy showed that Weber died at about 5:25 a.m. of asphyxiation when his torso was crushed in the equipment, a deputy coroner said. The death was ruled an accident.
Weber had recently celebrated his 34th anniversary working as a "tank man" monitoring machinery at Glenshaw Glass, according to Marci Weber, his wife of six years.
The couple met at the plant and were members of Local 134 of the Glass, Pottery, Plastic and Allied Workers union.
"We always worked opposite shifts, though, once we were married," Marci Weber said. "It was better for us and for our kids."
Marci Weber described her husband as easygoing, and a wonderful father to stepsons Ron Condrin, 15, Christopher Condrin, 14, and Dan Condrin, 12.
"Everyone loved him," she said. "He was such a good influence for my boys."
Allegheny County detectives are investigating.
Neither company nor union officials could be reached for comment.
A federal Occupational Safety and Health Administration Web site with information dating back five years shows no safety violations at Glenshaw Glass during that time.
The company had been forced to furlough many of its workers after the Sept. 17 floods caused major damage at the Shaler plant, but neither of the Webers was put out of work.
Clark Weber also is survived by a brother, Ken Weber, of Shaler. Funeral arrangements are pending.
