Opinion

ORDER OF JUDGMENT FOR DEFENDANT

KAESS, Chief Judge.

This is a civil action for damages. Plaintiff has claimed fraud, breach of express warranties, breach of implied warranties, and negligence. Jurisdiction is based on diversity of citizenship. 28 U.S.C. § 1332.

After plaintiff had completed the presentation of its evidence, the defendant moved for a dismissal, on the grounds that, upon the facts and the law, plaintiff had shown no right to relief. Rule 41(b) Federal Rules of Civil Procedure. On December 1, 1972, this court granted the motion and dismissed Counts I, II, III and IV of plaintiff’s complaint, 358 F.Supp. 449.

The trial then continued only with respect to Count V, which involved the alleged negligence of the defendant.

The facts and circumstances surrounding this case were set forth in the opinion and order of December 1, 1972 and will not be restated here.

However, at the outset the court reiterates that at the time the parties entered into the contracts involved in this case, neither of them knew precisely what manufacturing parameters were necessary to produce dry resinated pads. Plaintiff thought it did; however, subsequent events have proven this belief to have been erroneous.

I. Defendant Was Not Negligent.

It is the court’s finding that the evidence as presented by the defendant is more worthy of belief and that, based on this evidence, the defendant was not negligent in the design or manufacture of the dryers involved in this case.

Specifically, the court finds that the structures of the dryers were adequately designed from a strength standpoint, as well as from the standpoints of rigidity and deflection. The court bases this finding of fact on the opinion of defendant’s expert, Dr. Despres, whose opinion was based upon structural analysis utilizing accepted engineering practices and upon the physical examination of the subject ovens in the field, as well as the viewing and examination of the Globe machine in operation.

The structural aspects of the jack support points are adequate. The bearing load is not supported on the fan side solely by two-inch longitudinal tubing. The total framework of the fan section *469 of the oven, including the heavy fan support brackets, roof members, jack line shaft support structures and motor mount support structures, act as a system bearing the load and keeping the total deflection at each jack point reasonably uniform.

The evidence also established that the ovens utilized an independent adjustment procedure in the jack screws as a means of compensating for deflection in the structure. The adequacy of this procedure for maintaining close tolerance is clearly established by plaintiff’s ability to hold a level of .010" across the jack points (Exhibit 73). Further, plaintiff’s own report shows the jacks remain level from side to side during the raising and lowering of the compression conveyor frame.

Turning to the allegations of weakness in the side plates of the compression frame, the evidence establishes that the maximum deflection that would be attained would be under 0.006 of an inch between jack points. The worse condition is experienced with no material between the conveyors. The introduction of material between the conveyors reduces the deflection by permitting the carrying conveyor structure to assume a portion of the load being supported by the jack screws.

There is ample evidence to support a finding of fact that the design of the conveyor flights did conform to the design criterion set forth in the contract.

Portions of each of the four conveyor assemblies were subjected to loading tests. The physical measurements taken at the girt and at the hinge, at both elevated and room temperatures, clearly show that under 30 lb/ft.2 uniform loading the deflections are well within ± Vs2 of an inch. Indeed, with loads of up to 50 lb/ft.2, the deflections are within the ± V32 of an inch (Defendant’s Exhibits 335, 336, 337 and 338).

However, the loading conditions within the ovens while operating at 30 lb/ft.2 on the product are substantially less than the test loadings. Each conveyor section experiences approximately 15 lb/ft.2 force by virtue of its own weight. The conveyors are essentially flat in an unloaded condition and the deflection resulting from their own weight is negligible and of no consequence. The plates are designed to be flat under their own weight in an unloaded condition.

During actual operation, a deflection near the design criteria limit could exist at the hinge of a single conveyor flight under 50 lbs/ft.2 loading with the hinge wire of too small a diameter. However, Shegda and Flaith both testified that hinge wires of .156 diameter were supplied for both lines. However, the installation of such hinge wires would reduce the deflection as observed during testing of the hinge point deflection (Exhibit 338).

The finding of fact is inescapable that, under a uniformly distributed load of 30 lb/ft.2, the conveyors deflect substantially less than the contract criteria.

The plaintiff has offered certain proofs to support its conclusion that negligent design is shown by the inability of the flights to take a thirty-pound load and hold the ± %2 of an inch tolerance when cold. This evidence takes the form of its loading tests conducted upon a single conveyor flight.

The data obtained by plaintiff is invalid and misleading in several important respects. Primarily the testing of a single conveyor section ignores the contract description, and does not accurately reflect operating conditions within the oven. In operation, each conveyor is tied to the other through the piano hinge in a continuous belt. Each flight is designed so as to give strength to the adjoining flight as an integrated system.

Of equal importance is the method chosen by plaintiff to load the single flight. A 50-pound three-foot long steel bar placed on a 2" x 4" piece of wood seven feet long was used in plaintiff’s test. Plaintiff claims that such a loading of a single conveyor flight at the hinge edge furthermost from the girt was equivalent to a uniform load of *470 about 10 lbs/ft.2. However, this is incorrect.

A 50 lb. load spread over the area of the piece of wood beneath the three-foot steel bar is equivalent to an actual loading of 55.6 lb/ft.2. The next important factor rendering the test invalid is the placement of the load at a distance furthermost from the centroid of the flight. This placement of load creates a moment of force quite different than that experienced under a uniform load.

The evidence established that the effect of such an off-center load was to create a comparable uniform load of several times the 55.6 lb/ft.2. The result was a twisting of the conveyor flight in addition to deflection, both of which were measured by Meldrum in giving his testimony that the single flight deflected over five times beyond the ± %2 tolerance.
