1. Master and Servant—Negligence of Employer—Expert Testimony.The negligence to which the plaintiff ascribes his injury in this case, and which he charges against the defendant, is that a lag screw which was used to hold in its place the journal or box in which the axle of the drum rested, upon which were wound the
It was claimed by the defendant that the purpose of the lag screw was not to hold the box from raising up from the timber, but to keep it from slipping along upon the timber; that the strain upon the cables, caused by the weight of the platform, had no tendency whatever to lift the drum or its axle from off the timber, and that there was, in fact, no strain or force applied to the box or the lag screw that tended to pull it up from or out of the timber; that, 'therefore, it was of no particular importance whether the screw threads were capable of resisting an upward pull or not; and that it was plain that it answered its full purpose to hold the box from slipping horizontally along the timber on which it rested, because it did not so slip, but the screw in the other end of the box, and the box itself at that end, was still in place, even after the platform fell. For this reason he argues that it was not owing to the lag screw pulling out that the box was raised up and the drum disconnected from the worm, but that the disconnection occurred from some cause unknown to any one, and the screw was pulled out and the box lifted by the force of the falling platform.
Evidently, the ultimate question which the jury were to determine was whether the insertion of the lag screw into the crack between the timbers was an unsafe and careless mode of fastening the box to the timber, and therefore a breach of the defendant’s duty to the plaintiff. But the answer to this question depended upon their con'
If the screw would hold as firmly in the crack as in solid wood, then it was not an unsafe method to insert it that way. If there was no strain in the construction of the system tending to lift the box or draw it up from the timber, then it cannot be supposed that it was negligent not to guard against such a strain; and it cannot be supposed that the steady and constant strain on the cables, as re■quired in their usual and ordinary work, overcame the resisting strength of the lag screw, or that its yielding and drawing out caused the fall of the platform. If, however, the timber was liable to shrink, and thereby loosen the hold of the screw, and if there was a strain from the cables, or from any other source, that tended to draw up the box, and thus pull on the lag screw, it might well be that it was the defect in that screw that caused the accident.
It is a very serious question whether the decided weight of the •evidence is not with the defendant on these questions. The witness •Gifford, who invented the machinery in question, testified that there was no strain or force tending to lift up the box from the timber to which the lag screw held it; that the strain was entirely lateral or •downward; and that if the lag screw was taken out it would not lift the box up from off the timber. Another witness—an engineer— testified that the strain upon the drum was entirely lateral, in the direction towards which the cables led, and that no force tended to lift the box from off its seat. The plaintiff upon these two questions gave no evidence, except as follows: After putting to the witness Walsh, who was a carpenter and builder, a hypothetical question which gave, a description of the machinery in question and the conditions involved, he asked this question: “In your opinion as a ■carpenter and builder, would that be a reasonable, safe, and proper method of fastening that drum cylinder to the support ?” Under the defendant’s objection and exception, the answer was, “I don’t think it would.” Then the further question ^as put, “In your opinion, . Mr. Walsh, would a cylinder and drum required to support the weight that I have mentioned, and fastened as described in the last question, be liable to pull out with the weight so put upon it, fastened in this way?” Under objection and exception, the answer was, “I think it would; yes, sir.” It is to be noticed that his attention is nowhere particularly called to the lag screw. Upon the whole construction as given in the hypothetical question, he thinks the drum would be liable to pull out, but just what he considers the defect in the structure he does not state. On his cross-examination he states that the strain would be horizontal, in a line with the cables, and his
But it is not necessary to decide this appeal entirely upon this question of fact, for the exception taken to the question first above stated, as put to the witness Walsh, requires a reversal of this judgment. The question put was whether that method of fastening the drum cylinder to the support was a reasonably safe and proper one. That was the precise question which the jury must answer, and upon which their verdict was to rest; and, as suggested above, it depended to a large extent upon certain facts which were the subject of expert evidence, but which could be easily placed before the jury by the evidence of experts. When such is the situation, I understand the rule to be thoroughly settled that the experts may be inquired of as to such facts, but that, having instructed the jury with regard to them, it is the province of the jury alone to apply those facts to the question at issue. Dougherty v. Milliken, 163 N. Y. 527 , 57 N. E. 757 ; Harley v. Manufacturing Co., 142 N. Y. 31 , 37, 38, 36 N. E. 813 ; Ferguson v. Hubbell, 97 N. Y. 507 , 49 Am. Rep. 544 .
Clearly, it was possible to have asked Walsh directly for his opinion as to the effect of putting a lag screw into the crack between two timbers, and also as to whether there was any upward strain or force tending to lift the box and drum up from the timber on which it was fastened, and he could have given the jury all the information which he possessed upon those subjects. But, within the rule above cited, that was the extent to which his opinion could be taken. Instead of limiting the question to those matters, however, it goes to the full extent of taking his judgment as to whether the mode of fastening used by the defendant was a reasonable, safe, and proper one. Thus, the jury were allowed to lean upon his judgment as to what was reasonable, as well as safe and proper, instead of forming one of their own. Moreover, as suggested above, the jury were not informed by his answer just what his reasons for that judgment were. Why did he consider it unsafe? Was it owing to a defective lag screw, or did he possibly consider that something more than the intersection of the cogs in the rim, with the thread of the worm, should have been used to keep the drum from turning when not in use? Or did he, perchance, find some other criticism upon which he based his conclusion? Possibly, his opinion, which the jury have adopted, was based upon some fact not disclosed, and entirely different from the one for which the defendant is charged with neglect.
It is urged by the plaintiff that the rule laid down in the cases above cited has been changed by the recent case of Finn v. Cassidy, 165 N. Y. 584 , 59 N.
I conclude, therefore, that it was error to allow the question, and that the exception was well taken. For these reasons, the judgment and order appealed from must be reversed, and new trial granted, with costs to appellant to abide the event.
