Patent number: 4381183Abstract: An apparatus for removing a waste portion from a blow molded article is disclosed. The apparatus removes the waste portion while the article is enclosed within the blow mold and features a gripping structure for gripping the waste portion and a power assembly associated with the gripping structure to move the gripping structure from the article, thereby pulling the waste portion from its point of attachment with the article. The gripping structure includes two opposed gripping means which are arcuately movable about their respective pivot points. Each pivot point is laterally displaced from the gripping structure and positioned along a line extending through the shortest distance from the pivot point to that portion of the gripping structure which is closest to the attachment of the waste portion to the article.Type: GrantFiled: October 22, 1981Date of Patent: April 26, 1983Assignee: Ethyl Development CorporationInventors: Kenneth E. Bowers, Charles E. Markley

Patent number: 4379688Abstract: An injection blow molding apparatus capable of achieving biaxial orientation and the produced article is disclosed. The apparatus features a transport table rotatable about and reciprocally movable along its center axis and at least an injection molding station and a blow molding station positioned adjacent to and around the transport table. There is at least one core rod mounted to the transport table, which core rod is moved from the injection molding station to the blow molding station by the table movements. The core rod coacts with the injection molding station to form an injection molded parison which is transported on the core rod to the blow molding station. At the blow molding station, a stretch pin mounted within the core rod is utilized to aid in the biaxial orientation of the final article blown at the blow mold station.Type: GrantFiled: September 14, 1981Date of Patent: April 12, 1983Assignee: Ethyl Development CorporationInventors: Dennis J. Tate, Henry Trevino

Patent number: 4328887Abstract: This invention relates to a multistation apparatus for unloading and unscrambling containers from a storage hopper. The apparatus has unloading means for continuously moving containers from the hopper onto a track structure. The track structure is powered so as to move the containers to the various apparatus stations. At the first station a gate is positioned over the track so that only one layer of unloaded containers is able to travel to other subsequent stations. A second station is provided with orientation plates adjacent the track so that containers which are on the track but which do not have their long axis in the direction of container travel will, upon contact with the orientation plates, be turned so that their long axis will lay in the direction of travel. A gate having an opened and closed position is provided at the third station.Type: GrantFiled: April 7, 1980Date of Patent: May 11, 1982Assignee: Ethyl Development CorporationInventors: James D. Beard!, Donald J. Nelson, Kirk J. Haller, Kenneth E. Bowers

Patent number: 4198886Abstract: An apparatus for deflashing a plastic article is disclosed. In operation, an operator places the article having flash in a nest which positions the article so that the flash is in a horizontal plane. A powered shuttle assembly picks the article up from the nest and places it upon an anvil. The anvil has striking edges which follow the line of juncture between the article and the flash. A punch apparatus is lowered onto the article and strikes the flash at the line of juncture disjoining the flash from the article. The power shuttle then removes the article without the flash to a discharge point. Optionally, at the discharge point, there may be provided an orientation assembly wich orients the deflashed article so that it may be placed upon a conveyor belt which carries the article to a collection point.Type: GrantFiled: September 12, 1978Date of Patent: April 22, 1980Assignee: Ethyl Development CorporationInventors: Kenneth E. Bowers, Stephen E. Merritt, William G. Kinslow, Jr.

Patent number: 4197954Abstract: A thermoplastic container suitable for packaging frozen products is disclosed. The container has a hollow body having a hollow neck at its upper end, and a bottom wall at its lower end. The bottom wall, in one embodiment, has an oval center portion and a circular, upwardly and inwardly extending, connecting wall which is connected at its circumference to the lower end of the hollow body and is connected at its innermost extent to the oval center portion. In another embodiment the hollow body has an oval bottom wall which has a circular center portion. Connected to the circular center portion and the lower end of the hollow body is an oval, upwardly and inwardly extending, connecting wall which is connect at its circumference to the hollow body and at its innermost extent to the circular portion.Type: GrantFiled: October 5, 1978Date of Patent: April 15, 1980Assignee: Ethyl Development CorporationInventors: Eugene W. Oltman, Robert N. Hills
