The appellant, Pryor, was injured in the course of his employment on an oil well drilling rig, when the mast, sometimes called a derrick, collapsed under the tensile strain of a pipe-loosening and pulling operation. Having received workmen’s compensation under the laws of Oklahoma, Pryor and his employer’s compensation insurance carrier sued the appellee-manufacturer of the derrick as in MacPherson v. Buick Motor Co.,
The trial court, however, directed a verdict and entered judgment for the defendant-manufacturer, on the grounds that fifteen years of safe use for the purposes for which the equipment was intended foreclosed any probability that it was defectively or negligently made. The court followed Lynch v. International Harvester Co. of America, 10 Cir.,
The appellant would distinguish that case from ours for latent defects here and readily discoverable ones in the Lynch case. But the question whether mere lapse of time forecloses probability of negligent manufacture was squarely presented and decided in the Lynch case. The same question is presented here, and we must therefore now decide whether we will follow or recede from the Lynch doctrine. The Lynch case also arose in Oklahoma, but no Oklahoma case was cited in support of the rule. And, while Oklahoma has embraced the full vigor of MacPherson (i. e. see footnote 1), it has neither approved Lynch nor had occasion to consider the precise question. It has said only that if a device is suitable and safe for the purpose for which it is to be used when sold, the manufacturer has then discharged his duty to those who thereafter use it. Jamison v. Reda Pump Co.,
Only recently, the Fifth Circuit, following its conception of Texas law, deliberately refused to adopt a policy of foreclosing liability after prolonged use without defective failure. It did not think the lapse of seven years per se relieved a derrick manufacturer from liability for injuries caused by a defective weld. International Derrick & Equipment Co. v. Croix,
The proposition that prolonged safe use bars any inference of negligent manufacture has not gained wide acceptance in the application of the MacPherson doctrine. As far as we have been able to ascertain, the Lynch case has been followed and applied in only a few isolated cases involving this proposition. Solomon v. White Motor Co., D.C.,
Apparently quite apart from the time element as an intervening cause, the trial court did not think the plaintiff proved the issuable fact that the defective weld caused the derrick to collapse as it did. There was no direct evidence of proximate cause, and indeed there need not be, for proximate cause is often left to permissible inferences from established facts. Mealy-Wolfe Drilling Co. v. Lambert,
The case is accordingly reversed and remanded for a new trial.
Notes
. Oklahoma embraces the doctrine of this case to the eifect that “The manufacturer of an appliance that will become highly dangerous, because of defects in its manufacture, when put to the use for which it is designed and intended, owes to one purchasing and using such appliance, the duty to use reasonable care in its manufacture; and failure to discharge such duty may constitute negligence.” Gosnell v. Zink, Okl.,
