Portrait of Melville Fuller Melville Fuller Olin v. Timken — Opinion of the Court

It is true that the Tilton patent, both original and reissue, showed the light ends of the springs secured to the side bars by links or swinging shackles, while the shackles were rigid in the Timken; but both these shackles were well known, and complainant cannot contend that the difference is material.
In short, the Tilton patent relates to a crossing spring with a pivot bolt at the intersection. The Timken spring is the Tilton spring with the pivot bolt omitted; but in the defendants' spring the two sections do not cross each other, and cannot have a pivot bolt at the intersection.

Appellee's argument seems to be that the Timken patent should be so construed as to cover a double-sweep, sectional spring, having the attaching ends connected to the bottom of the buggy or cross sills at any point between the side and the center, crossing the center, bending downwardly for a distance, and then upwardly to be attached to the side bar; having a thick end for attachment to the buggy bottom, and a thin end for attachment to the side-bar shackle, the curve being such as to allow the body to move up and down without expanding the side bar

The springs are arranged to cross each other at the center of the cross bar, B, upon which the carriage body is placed, and their elevated or upper ends are permanently secured at the opposite ends of said cross bars by means of bolts and nuts, a. Each spring is provided with a socket, c, at the crossing point, and through said sockets, which are thus brought in line with each other, an axis or pivot bolt, D, is passed. A nut, b, is applied to the screw-threaded projecting end of the bolt for securing the same in place.
