258 F. 143 | 2d Cir. | 1919
But claim 3 of the reissue is literally the same as claim 3 of the original patent, and claim 5 of the reissue is literally the same as claim 4 of the original patent. These claims should be construed consistently with the specifications, which are also literally the same in each patent, as meaning that the spiral coil is rigidly connected with the longitudinal bar at each point of contact. So construed, the claim describes a continuous spiral rigidly and integrally connected with kerfs and spurs in the bar, constituting a trusslike structure within the body of the concrete, resisting lateral and longitudinal strains, and which can be-more cheaply manufactured than if'the spiral were riveted or welded to the bar at each point of contact.
The decree is reversed, with half costs to the plaintiff.
