Sorensen v. J. I. Case Threshing Machine Co.

129 Wis. 366 | Wis. | 1906

Oassoday, O. J.

1. Errors are assigned because the court refused to grant a nonsuit, and refused to direct a verdict in *369favor of the defendant, and refused to change the answer of the jury to the first question submitted from the negative to the affirmative, and the answers of the jury to the second and third questions from the affirmative to the negative. These alleged errors are all discussed under the general proposition that the evidence on the part of the plaintiff fails to establish any actionable negligence in the construction of the machine. A description of the machine and its operation and the manner in which the injury was inflicted are sufficiently set forth in the foregoing statement. In addition to the facts thus conceded there is evidence on the part of the plaintiff tending to prove that were several punch machines in the boiler shop; that there was a certain amount of jar or vibration caused by the operation of the machine as it was ordinarily used; that the motion of the machines jars the rods and vibrates the crane, and that the vibration of the crane and the standard vibrates the supporting rods; that a five horse-power motor was applied to punch these iron pieces, but it is geared up to such an extent that it develops a good deal more than five horse-power; that every time a hole is punched through the sheet of iron the whole machine is jarred, including the rod and crane; that there are from 150 to 200 holes in a tire sixteen feet long and twenty inches wide; that carrying a load on that crane of 1,000 pounds with the carrier about midway on the arm, pointing in a southeasterly direction, the strain, with reference to the two rear rods, would be mostly on the northwest rod, which was perfectly straight, except where the eyebolt went through the iron beam, and there there was an angle where the two pieces were tied together; that the eyebolt and the long piece formed the angle at the place where the one engaged with the other; that the machine in operation jarred or vibrated the rods, standpost and punch; that the action, of the punch caused the jar; that there was heavy pounding and punching going on all the time and more or less jarring throughout the entire shop; *370that there was nothing unusual in the load being lifted at the time of the accident; that the tensile strength of iron was a •pull — the tendency to lengthen; that a side or breaking strain of iron was a transverse stress or bending strain; that the ■cause of the breaking of the eyebolt was the fact that it was too weak to carry the load. In answer to the hypothetical ■question which assumed that the angle mentioned was substantially thirty-five degrees, as stated, by the defendant’s •counsel, an expert witness with much experience testified to the effect that where the vibration ceased at the angle in question was next to the nut, which caused the rod to crystallize; that as it crystallized it became weaker, and finally, when it became weak enough not to carry the load, it would break; that by crystallizing was meant that it would lose all the fiber of the iron and become a very different piece of material from the original; that in the absence of such fiber the surface of the iron looked more like a section of zinc; that the broken end in question was crystallized about one third across; that in the ordinary use of the crane the weakest point of the sustaining rod was just on the inner side of the nut, if both sides were screwed up solidly against the bolt on the side towards the crane, because that was the point where the leverage was placed — the leverage stopped there, — and in that four inches there was a strain on the diameter of seven eighths of an inch of about four and a half times the weight that was on the crane, tending to pull the bolt to the side and break it; that the strain on the eyebolt just next to the inner nut was a transverse or breaking strain, tending to break the holt; that, of course, the bolt was the weakest in that direction; that such construction was not mechanical; that the construction of the rod in question and the manner in which it was tied to the beam were not the customary way but an unusual way; that the principle of the eyebolt was all wrong because it stood at a right angle to the beam; that if the truss rod had gone directly through on a line then there would have *371been tensile strength of the whole rod instead of .a transverse section to bend; that the -usual and customary way of fastening devices of that character, where four tension rods are in use, would he a foot formed on the end of the rod and fastened right to the girder with bolts, so as to get a direct pull, or it could pass right through the girder with angling washers on it and screwed up square to the face of the nut; that the usual and customary way was to avoid a right angle, and that is done by a foot, as mentioned, when tension rods are used; that with the foot there would not be any movement, because it runs directly on a straight line, and it all becomes tensile strength, which is very much more than a transverse stress, which is a bending strain; that it is weaker with an eyebolt in it, and grows weaker every day the rod. is shaken and vibrated, because that is what produces crystallization; that crystallization is most frequently caused by sudden shocks, and so it may be caused by a continuous succession of shocks or blows, and so vibration would cause crystallization as shown by experience; that crystallization reduces the tensile strength of iron — not always so much, however, as the ductility and elongation; that assuming the angle mentioned to be about thirty-five degrees, with an eyebolt running at right angles with the beam, and then tied to a longer piece going to the stand, the weakest part of the rod in question would be at the nut.

The evidence on the part of the defendant tended to prove that the device which broke was put in about a year and a half before the accident, and that it was again inspected in the fall of 1904. We are constrained to hold that there was evidence sufficient to sustain the findings of the jury mentioned; and that such evidence was not, as a matter of law, conclusively overcome by uncontradicted evidence on the part of the defendant.

2. Exception is taken because the court, in charging the jury upon the question of contributory negligence and the as*372sumption of risk, after defining a want of ordinary care, stated that such “want of ordinary care was not a contributing cause to produce the injury unless there was a proximate connection between such injury and such want of ordinary care; that is, it must appear from the evidence that there was such a relation between the plaintiff's fault, if any, and the injury that such injury was a natural and probable result thereof.” The criticism is in the use of the word “fault,” ,which is not to be commended, but, as used, it obviously referred back to “such want of ordinary care,” and hence could not have misled the jury.

3. Error is assigned because the court charged the jury to the effect:

“If the plaintiff is entitled to recover at all in this action ... he is entitled to such sum as will fully compensate him for such loss of earnings 'as you are satisfied by the evidence he has reasonably sustained as a result of the injury; for all bodily pain and suffering and mental suffering which he has endured by reason of the injury complained of; and for such permanent injuries as you are satisfied from a fair preponderance of the evidence it is reasonably ceidain the plaintiff will suffer in the future by reason of the injury complained of. You will answer this question regardless of your answers to the other questions, and assess such damages as "you are satisfied by the evidence considered under the instructions given to you will fully compensate the plaintiff for all the elements of damage I have suggested to you.”

. The exception is to the words “will fully compensate.” But, as indicated in the language quoted, those words were expressly limited to “the elements of damage” which had just been mentioned in the charge of the court. As thus limited, we do not think such charge is inconsistent with the ruling of this court in the case relied upon by counsel. Guinard v. Knapp-Stout & Co. Co. 95 Wis. 482, 490, 70 N. W. 671. Nor is it inconsistent with later cases in this court on the subject. Candrian v. Miller, 98 Wis. 164, 167, 168, 73 *373N. W. 1004; Bergeron v. Peyton, 106 Wis. 377, 382, 383, 82 N. W. 291. We find no reversible error in tbe record.

By the Gourt. — Tbe judgment of tbe circuit court is affirmed.
