Kuzma v. United States Rubber Co.

October 22, 1963


Author: Mclaughlin

Before BIGGS, Chief Judge, and McLAUGHLIN and GANEY, Circuit Judges.

McLAUGHLIN, Circuit Judge.

Defendant appeals in this personal injury case from the entry of judgment in favor of plaintiff and the denial of its motions for judgment n.o.v. or, alternatively, a new trial.

Plaintiff, a grinding wheel operator in the hot roll shop of Jones & Laughlin Steel Corporation (J. & L.), was injured when an abrasive wheel manufactured by defendant disintegrated while being used by him. Plaintiff's cause of action was predicated on defendant's negligence and breach of warranty in the manufacture and sale of its wheel to plaintiff's employer. The defense was based on the contributory negligence of plaintiff in running the wheel at a speed in excess of the maximum rated speed that defendant had stenciled on its wheel. The jury returned a verdict of $20,000 and defendant has appealed to this court from the denial of its post trial motions.

At the time of his accident plaintiff was an employee with fifteen years of experience as an operator of a roll grinding machine in J. & L.'s hot roll shop. His duties consisted of grinding down the large rolls used in the steel making operations of J. & L. in order to remove the bruises and marks which develop on the rolls in the course of their use. This regrinding is done by the use of an abrasive grinding wheel which is machine mounted and controlled by a variable speed motor. The different speeds of the wheel are controlled by a rheostat that, at the time of this accident, was only calibrated by marks at each quarter. Plaintiff was using a 36inch rubber bonded wheel on the day of his injury, the first wheel of its kind to be utilized in J. & L.'s hot roll shop. Prior experience had demonstrated that resinoid or shellac bonded abrasive wheels were best suited for this type of work. However, defendant's salesman, Cornelius, had persuaded plaintiff's foreman to try out its 36inch rubber bonded wheel on the representation that the prior drawbacks of rubber bonded wheels had been corrected and that this new wheel had been "hardened up" and would do a satisfactory job. It was during the trial run of the defendant's wheel that the unfortunate accident occurred.

Defendant's first assignments of error are directed to the testimony of plaintiff's expert witness, Venable. It contends that the court below erred in permitting him to "speculate" at length concerning the cause of the accident and testify to several facts without an adequate factual foundation.

At the trial defendant very ably argued that Venable was not qualified to testify as an expert witness concerning the structure, components, or manufacture of abrasive grinding wheels. After both parties had conducted a careful and extended examination of the witness' qualifications in this field defendant's objection on the point was overruled by the court. When it later raised the same objection as one of the grounds in support of its post trial motions it was again overruled. Defendant does not challenge the ruling but instead it is now in the position of raising specific objections to the testimony of Venable that, with one exception, were not presented to the trial court. The general rule, of course, is that alleged errors in a jury trial which are not brought to the attenion of the trial court will not be considered on appeal. United States v. Atkinson, 297 U.S. 157, 56 S. Ct. 391, 80 L. Ed. 555 (1936). In any event, we find no merit in the present objections since, for the most part, they represent nothing more than dissatisfaction with the opinions that plaintiff's expert gave contrary to the views of defendant's witnesses.

Defendant is primarily disturbed by Venable's testimony that in his opinion the specific grinding wheel in question was damaged during its manufacture.*fn1 Initially, it stresses that Venable knew nothing about the manufacture of the specific wheel, the implication being, therefore, that this fact vitally affected the factual basis for his opinion.*fn2 As a practical matter, such an absence of "personal" knowledge is found in most personal injury cases of this nature, and is a factor properly addressed to the qualifications of the witness offered as an expert on the subject. More fundamentally, defendant contends that the expert's opinion that the wheel was damaged in the course of its manufacture was mere speculation and conjecture. We cannot agree that the trial court abused its discretion in this respect, for, though scant, there was some factual basis from which Venable could infer that the wheel was damaged. According to the manufacturing specifications of defendant there were to be three steel safety rings set in the wheel during its manufacture, whereas an examination of the wheel fragments by the expert witness after the accident revealed that the third ring was missing and in its place a hard plastic material substituted. Venable's analysis of the wheel fragments revealed that the third ring had originally been placed in the wheel during the manufacturing process but had been removed or broken out at a later point. This conclusion was corroborated by defendant's own witness. The reason for the absence of the ring therefore became a highly significant trial factor.

It was in light of the above circumstances, as well as his own expert knowledge of the compression molding process and his examination of defendant's molding instructions and inspection reports that Venable gave his opinion of why the third safety ring had been removed from the wheel. In essence, he concluded that in the course of removing the wheel from the mold while it was still in a brittle state a portion of the wheel containing this ring broke and in reparing the break the ring space was filled with the plastic material. The explanation offered by defendant for the ring's removal differed materially. The conflict, however, was for the jury to resolve, c. Sanders v. Glenshaw Glass Co., 204 F.2d 436, 440 (3 Cir., 1953).

Defendant next complains that the opinion of plaintiff's expert that the grinding wheel contained less sulphur - the wheel's vulcanizing agent - than was required by the specifications was also without adequate factual support. We note again that defendant is raising an objection for the first time on appeal. In any event, this contention is of no real significance. Defendant analyzed a few of the wheel fragments recovered after the accident and found a lower percentage of sulphur in these samples than called for by the original formula. On the basis of defendant's finding and Venable's personal knowledge of what he considered to be the usual procedure in writing up that type of report which contains figures differing from the original specifications, Venable concluded that an insufficient quantity of binder was put in the wheel. While we might feel that this conclusion was incorrect and that defendant's explanation for the difference between the figures was more reasonable, we cannot say that there was no factual support for Venable's opinion.

Defendant raises two final objections to the testimony of plaintiff's expert witness. First, it suggests that the court erred in permitting Venable to testify concerning the different sizes of wheel fragments that result from a wheel failure caused by overspeeding and a wheel that breaks because of a defect. Second, that Venable should not have been permitted to testify to the ordinary operating speeds of grinding wheels. The nub of the objections is that Venable was not qualified to speak as an expert in these instances. Having in mind defendant's admission that it is not now attacking the qualifications of this witness, no further discussion is needed as to these points.

Defendant argues, as a further ground for reversal, that the court below erred in denying defendant's motion for judgment n. o. v. or, alternatively, a new trial, when the evidence unequivocally demonstrated that plaintiff was contributorily negligent in operating the grinding wheel in excess of its maximum rated speed and in disregard for his own safety.

It is well established under the applicable Pennsylvania law that "'[it] is only in those cases where contributory negligence is so clearly revealed that fair and reasonable individuals would not disagree as to its existence that it may be declared judicially.' * * * 'It is only in clear cases where the facts are undisputed and but one inference can be drawn from them that courts can declare as a matter of law a party guilty of contributory negligence * * *.'" Thorton v. Aronoff, 279 F.2d 39, 40 (3 Cir., 1960). And as we noted in Thorton, supra, 279 F.2d at 40, a finding that plaintiff is contributorily negligent as a matter of law is a severely limited exception to the general rule that this question is for the jury.

Our study of the record convinces us that the question of plaintiff's alleged contributory negligence was properly submitted to the jury. The evidence favorable to plaintiff shows that: Plaintiff was instructed by his foreman, Braemer, to put on defendant's new grinding wheel in order to check its performance. He was to use the wheel in a normal operation, and, in the same manner as he would use any other wheel, procuce a finished roll by going through the usual processes of roughing, shaping and finishing. Although Braemer initially had been skeptical about whether the 742 r.p.m. rated speed of defendant's wheel was high enough for their normal use at J. & L. he made no mention of his doubts to plaintiff. He failed to warn plaintiff about overspeeding before the latter began his work, though he knew that the grinding wheel operators in the plant were accustomed to use higher speeds in excess of a wheel's rated maximum. Furthermore, the minimum speed at which ...
