  • Patent number: 6044748
    Abstract: Reliability of a multi-lug breech bolt is improved by modifying the bearing relationship between the bolt lugs and the matching lugs within a gun receiver. This procedure is applied to a gun that has a receiver housing a breech bolt and an extractor. The extractor is coupled to the breech bolt and configured to move relative thereto. The bolt for this gun has at least five radially extending bolt lugs configured for bearing contact with the receiver when positioned for firing. The bolt lugs include a first, second, and third bolt lug with the first and second bolt lugs being adjacent and defining a gap configured to receive the extractor therebetween. The third bolt lug extends from the bolt opposite the gap. Stress imparted to the first and second bolt lugs from firing the gun is reduced by altering the gun to prevent formation of a bearing relationship between the third bolt lug and the receiver when the bolt lugs are positioned for firing. The gun is reassembled as part of the procedure.

  • Patent number: 5580474
    Abstract: The present invention is a receiver made by a welding process. The receiver made according to this process has less net distortion because of a number of techniques used in the process, including: (1) cooling the weld with Carbon Dioxide (CO.sub.2) preheated with the welding torch tip; (2) use of not more than approximately 4% oxygen in the shield gas to enable hotter, faster welding; (3) the use of a reduced voltage and wire feed rate at the end of a weld to avoid cracking; (4) the intentional use of distortion to reduce net distortion; and (5) sequencing of welds to reduce distortion. Distortion can be introduced in the stamped parts as they are made or when placed in a fixture for welding that, when welded, have less distortion than before. Distortion can also be countered by welding parts in a sequence where a subsequent weld reduces the distortion of a previous weld.

  • Patent number: 4563039
    Abstract: A hinge joint which connects the back to the remainder of the seat in a motor vehicle has first and second leaves respectively provided with punched internal and spur gears. The internal gear receives the spur gear and at least one of its internal teeth meshes with two neighboring external teeth of the spur gear or vice versa. The rear sides of the internal and external teeth are formed with punched indentations to compensate for shrinkage of the top lands of such teeth as a result of punching. Each indentation resembles the frustum of a pyramid and is designed to effect the flow of material toward the top land of the respective tooth. The two leaves are coupled to each other by a shaft which defines therefor two parallel pivot axes.
