delivered the opinion of the court.
At about 5 o’clock on the evening of October 26, 1891, one of the boilers of the Louisville Electric Light Company exploded, and caused the destruction, by fire, of the wholesale and retail dry-goods and dress-making establishment of Kaufman, Straus & Co., situated across an alley in the vicinity of the electric plant. While there were other persons in the room adjoining the boiler room, there was only one person immediately at the boiler when the explosion occurred; and that person was the fireman Adams, who was killed by the explosion. Some months after the destruction of the establishment, Kaufman, Straus & Co., having been paid in the meantime the sum of $195,500 on account of some 60-odd policies of insurance held by them, but which they averred did not fully cover the real value of the goods and other losses, brought this action, in Law and Equity Division of the Jefferson circuit court (equity side), to recover in their own right, and in behalf of the insurance companies (some of whom were made co-plaintiffs and others defendants), the aggregate sum of $242,557.72, against the electric light company and the Louisville Gas Company; it being averred that the latter company was the real owner of the former company,. and was in fact operating the electric plant at the time of the explosion. The insurance companies which had been made defendants came in by answer, counterclaim,, end cross petition, and in effect joined in the suit with.
Waiving the question at present as to the ownership of the electric plant, and the responsibility for the explosion on this ground, we shall proceed to consider briefly the facts relied on to show negligence. Tn the boiler room there were seven boilers, No. 7, the one that exploded, being situated next to the alley on the other side of which the rear end of the storehouse of Kaufman, Straus & Co. was situated. This boiler was connected with its mate,
We have not failed to read and give due weight to the proof in criticism of the size of the blow pipe, called also the “equalizing pipe,” and the occasional defects in the feed pumps. But the fact is shown by the plaintiffs’ own testimony that, on the day of the explosion, “the boilers equalized pretty well,” and the blow pipe was in good order at 3 o’clock, when the fireman, Adams’ predecessor, went off duty; nor was there any difficulty then in feeding the boilers. Noble also testifies: “If a man had come to me ten minutes before I went off watch (some 2% hours before the explosion), and asked me if I was afraid of the boiler, I would say that I would risk 130 pounds of steam on it. They were running 115 pounds when I went off
The testimony of two witnesses, and two only, out of a large number introduced by plaintiffs who had the same advantages in examining the wreck as these two had, is to the effect that after the explosion there was a distinct water line across the boiler at the level of the lower one-third of the flue, convincing the witnesses that, at the time of the explosion, the part above the water line had been red hot, and the part below had been protected by the water. This is formidable proof, and seemingly conduces strongly to show the lack of water at the time of the explosion. But the force of it is greatly weakened, if not'destroyed, when we find that the other experts and practical boiler men introduced by the plaintiffs, and who made careful examination of these same flues, do not speak at all of this “distinct water line,” or of any sign of that
Against these opinions and problematical speculations.
The difficulty we have in coming to any satisfactory conclusion as to the cause of the explosion, growing out of the fact that those learned in the business at hand come to different conclusions from the same data, is still further increased when we examine the testimony of perhaps the most distinguished expert introduced by the plaintiffs. Prof. Brown, who, as plaintiff shows, is professor of steam engineering and machine design in the Rose Polytechnic Institute of Terre Haute, Ind., and who was educated at the Sheffield Scientific School of Yale University, testifies substantially that, at the instance of the plaintiffs, he tested certain parts of the exploded boiler, “to determine the strength of the material, its elastic limit, its ductility, and its thickness,” making four separate tests. The thickness was .2375 of an inch. The tensile strength was 42,900 pounds per square inch of section. He found an elastic limit of 22,103 pounds per square inch of section of elastic
The importance of these tests will be shown better by a quotation from the testimony of this witness, as continued by the plaintiffs:
“(21) I will ask you to state whether or not the examinations and tests to which you submitted these specimens were or not thorough and exhaustive. A. They were thorough and exhaustive. (22) If it be a fact that the original tensile strength of the iron constituting the boiler which exploded, and which is the basis of this litgation, was 55,000 pounds, and your examination of a part of it showed the tensile strength 42,900, what do those two facts indicate with reference to the condition of the boiler at the time the explosion took place? A. This indicates that a serious deterioration, or a very marked deterioration, had occurred in the quality of the material. (23) Does or does not the elongation percentage of three and seven-tenths indicate anything with reference to the condition of the iron which you examined? A. It indicates that the material had been stretched as far or nearly to its limit, and that its elasticity and resilience had been almost entirely eliminated. (24) If the boiler, of which parts thus examined by you, was originally one-quarter of an inch in thickness, and had a tensile strength of fifty-five thousand pounds, and the piece of iron which you subjected to examination was a part of that boiler, which had been used for about eight years, during which most of this time river water had been used in it, and at the end of which time an explosion of the boiler took place, how would you, if at all, explain that material deterioration in the quality of the iron which you have stated to be the result of your examination? A. I should say that, in the first place, the*150 deterioration which it showed in tensile strength had been caused by repeated and long-continued heating of the material, in which physical changes had taken place, result* ing in a material reduction in strength; that its lack of resilience or elasticity was due to excessive heavy pressures produced on it, or stress produced in it, by heavy steam pressure, or by contraction and expansion of the material, due to changes of temperature, or those causes combined. The reduction in thickness resulted, doubtless, from the corrosive action of the water, or of the fire, or the erosive action from the same causes. (25) Would or not a boiler of which the specimen examined by you was a part have been as strong as the same boiler when its tensile strength was fifty-five thousand pounds, and the thickness of it one-quarter of an inch? A. It would not. (26) Would the boiler of which that specimen was a part have been able to support a pressure of steam as great as the same boiler when its tensile strength was fifty-five thousand pounds, and its thickness one-quarter of an inch? A. It would not. (27) Would that difference make a material or immaterial difference? A. It would be marked. (28) I will ask you whether or not the owner or manager of the boiler of which that specimen examined by you was a part could, by the exercise of ordinary diligence, have known of its condition at any time. A. He could have known that it was weaker than when originally built, and unable to withstand the wearing pressure to which it had originally been subjected. (29) Could or could not he have known exactly what its tensile strength at that time was? A. He could, by testing a portion of it. (30) But, by ordinary inspection, he could not? A. He could not. (31) How. far would he have known its condition? A. That is a question which would be very difficult*151 to answer exactly. (32) If the boiler of which the specimen examined by you was a part was a flue boiler, twenty-four feet long, and forty-two inches in diameter, and was ordinarily subjected to a steam pressure of from 110 to 115 pounds, would you not consider such a pressure a safe working pressure for that boiler? A. I would not. (33) If the boiler mentioned had been ordinarily subjected to a working pressure of from 110 to 115 pounds, what, in your opinion, would be the effect upon its condition, and its ability to withstand any impulsive blows or other trifling accidents? A. I do not catch the meaning of that question. (34) I will put it in another form: If the boiler above mentioned was ordinarily subjected-to a pressure of from 110 to .115 pounds, would that fact in any manner enhance the risk of operating that boiler? A. It certainly would. (35) Please explain fully how that would have been brought about. A. While a boiler under ordinary conditions might withstand for a considerable period a pressure of from 110 to 115 pounds per square inch, there are causes which at times operate to increase the stresses produced by such steam pressures to a very considerable amount; as, for instance, if at any time the boilers are momentarily — the water in the boiler is quiet — that is, if no steam is being drawn off from the water, and if suddenly a valve is opened, or an opening made in any manner for the escape of steam, as by opening the valve to start the engine, or by the opening of the safety valve, the sudden formation of the steam is likely to occur in the water in the boiler, which formation will possibly or is likely to throw a large mass of water towards the opening of the boiler, and against the boiler plates, thus ^producing a blow, or impact, which greatly increases the stress on the material. (36) What effect would such occurrence have*152 upon the boiler plates ? A. If the boiler plates were weak, it would be very likely to rupture them. (37) Would or not such occurrence be likely to produce an explosion? A. It would. (38) Are there any otherwise trifling occurrences in boiler management that would, under some circumstances, produce similar results? A. That is, resulting in an explosion or laceration of the shell? (39) Yes. A. I presume there are many. (40) With a boiler in the condition stated, would or not otherwise trifling and unimportant occurrences tend to become serious? A. You mean a boiler of such thickness and under such pressure? (41) Yes. A. Do you mean, are there other trifling causes which might produce such results? (42) Yes. A. There are. (43) Enumerate some of them. A. It might be possible that a boiler which was loaded with an excessive steam pressure, and had an accumulation of scale in one part, and perhaps heated exclusively at that point, due to the non-conducting quality of the scale, if that scale should be loosened by the permeating of the scale by the water in the formation of steam, undoubtedly such cause might produce explosion by the formation by the large amount of steam and the increased pressure due to such formation. (44) State any other ordinary occurrence in boiler management which might have such effect. A. It might be possible, if a boiler were loaded excessively, that the opening of the furnace door and the sudden influx of a current of cold air might produce such contraction in the material of the plate being cooled as to cause a rupture of the shell. (45) Any other? A. If the water in the boiler is allowed to become very low, and cold water were pumped into the boiler onto very hot plates, the formation of steam in such a case might produce such excessive stress as to burst the boiler. (46) As to cause an explosion? A. As to cause*153 an explosion. (47) I will ask you whether or not a working pressure of from 110 to 115 pounds upon the boiler of which the specimens examined by you that day were a part, and which was 24 feet long and 42 inches in diameter, had been used about eight years, part of the time with river water, was a safe load for it to carry? A. It was not (48) What, in your opinion, would have been the limit of pressure for ordinary safety in such a boiler in the condition in which you found the specimens examined? A. I should consider such a boiler fit for the scrap heap; it should be discarded. (49) Give, if you can, your reasons for such a conclusion, and give them as fully as you please. A. My reasons are that the result of my investigation showed the material to be reduced in tensile strength, and almost entirely lacking in resilience, or the power to resist impulsive load; and, in consequence, it would, in my opinion, be unfit fo-r further use in boiler construction. (50) Do I understand, in your opinion, the operation of such a boiler under a pressure of 110 to 115 pounds was in any event unsafe, and likely to result in an explosion? A. It was. (51) That is your opinion? A. It is. (52) If it be a fact that, after the explosion of the boiler of which this iron examined by you was a part, there appears on the inner -side of the shell certain bluish marks at a height at or very slightly above the lower part of the flue, would or not such a fact indicate anything with reference to the height of the water at the time of the explosion? (Question objected to, because no facts in this record disclose any ground upon which to base the hypothetical case.) A. I should first endeavor to determine what those bluish marks or tints were caused by. If, on inspection, it was demonstrated to be oxide of iron, such as is ordinarily formed by the action of the air, or oxygen on the heated*154 surface of iron, or the action of superheated stem upon such a surface, I should consider that such a surface was not covered or protected by water, and if a distinct line appeared horizontally about the boiler,, above which line the surface of the material was coated by this iron oxíde, I should conclude that the level of the water had been below the surface so coated, and that the ..water had not been in contact with it. (53) To what other cause than such oxidation could such a blue line or tint owe its origin? A. A tint of that sort would possibly be produced by smoke, but such a tint or color could be easily determined by careful inspection by one who was familiar with the color and characteristics of oxide of iron. (54) If due to smoke, they could be easily detected? A. Yes; and probably wiped off. (55) If, then, such a blue mark or line were due to oxidation, and not to smoke, you would conclude that it marked the height of the water at the time of the explosion that might have taken place; is that correct? A. I should conclude that at the time of oxidation the water could not have covered that surface. (56) If such an appearance presented itself on the inner side of the shell of the boiler that had exploded, would it then, or not, indicate the line above which no water had been immediately previous to the explosion? A. I can not say that the coloring might not have been formed previous to twenty-four hours before such an explosion. (57) If such coloring had been produced, and the height of the water in the boiler had after-wards been raised above it, would such color be permanent^ or would it disappear? A. It would probably not be obliterated for some time, but no ordinary boiler would stand the pressure produced by such an operation. (58) If a boiler with the dimensions we have mentioned, and of which specimens examined by you had been customarily*155 subjected from 110 to 115 pounds, why would it have been dangerous to operate it? A. Because the material was too weak to withstand the stresses which such a pressure would produce safely. (59) What could, in such a case, have produced the explosion of such a boiler? A. Any one of numerous trifling causes, a few of which I have enumerated, might have caused an increased stress in the material as to produce a rupture. (60) What are your duties at the Rose Polytechnic Institute? A. Teaching machine designing; designing machinery and steam engineering, both in practice and theory. (61) How' long have you been so engaged? A. Since 1888. (62) What sort of machinery, if any, did you use to make the examination of that specimen? A. I used a Riehle testing machine.”
Giving full credence to all the evidence introduced by the plaintiffs, we conclude that they have rendered it quite likely or probable that low water caused the explosion; and they have also made it probable that the cause is unascertainable; and they have demonstrated to a certainty that the reduction in the thickness of the exploded boiler, and the deterioration which the boiler showed in tensile strength, had been caused by repeated and long-continued heatmg of the material during the eight years of its service, and during which physical changes had taken place, resulting in a material reduction in strength, and that this lack of tensile strength, elasticity, and resilience was unobservable and unknowable except by breaking the boiler into pieces, and testing the parts; and, moreover, in the weakened condition in which the boiler was when it exploded, they have shown conclusively,, that a half dozen causes other than low water might easily have produced the explosion. Indeed, they have demonstrated almost beyond a reasonable doubt — and quite beyond such doubt
Upon the state of facts thus presented by the plaintiffs, the question before us is, not whether the finding of the court is with or against the evidence, or is flagrantly against the evidence, but the question is whether the law will authorize a verdict on the problematical data and the uncertain and shifting foundations thus laid by the plaintiffs. When the question is one of negligence or no negligence, it is well-settled law that, where the evidence is
The application or adjustment of these familar principles of law to the facts of this case, as presented by the plaintiffs, impels us to sum up the situation thus: It is fairly inferable from certain of the plaintiffs’ testimony that low water caused the explosion: it is also fairly to be inferred from other of the plaintiffs’ testimony that the cause was not ascertainable after careful examination; and, lastly, it is shown with reasonable certainty, upon the only scientific test and examination made, that the boiler was inherently weak, from physical changes occurring secretly, through long use, and which were not discoverable by ordinary and usual inspection, and that the explosion almost necessarily followed from the subjection of the boiler to the usual amount of pressure required in its customary operation. We conclude, therefore, that the evidence is not sufficient to authorize a judgment transferring the money or property of the defendants to the possession and profit of the plaintiffs. It is hardly necessary to say that this conclusion is fully sustained and fortified by abundant proof on the part of the defendants, showing careful and prudent management of the boiler and machinery, and that the explosion was not the result of negligence.
By reason of the view already expressed, the question of the gas company’s liability, because of its ownership of the light company’s stock, becomes unimportant. However,
It is argued that, by the purchase of the stock, the gas company was simply carrying out the purpose of its charter amendment, which enabled it to manufacture, distribute, and sell electricity for illuminating purposes. But, as we have seen, it did not acquire under its charter the right to manufacture and. distribute electricity, for supplying motive power. The electric light company alone had this right. If the gas company purchased the stock only as a means to an end — that of manufacturing and selling electricity for illumination — it would have confined the business to that end. It did not attempt to do this, but the light company continued to operate its own franchise with the power and rights conferred in its charter. It is not true that the gas company could only lawfully buy the stock by .assuming the ownership of the business. The gas company, by purchasing the stock of other companies, as authorized by its charter amendment, could at last only become a mere stockholder; and this the law-makers must be supposed to have known. It was therefore as a control ling stockholder, or, if need be, a single stockholder, that the law contemplated it might control the manufacture, sale, and distribution of electricity. In this sense and in this way, the stockholders of all corporations do own and control its business. Wherefore, for the reasons indicated, the judgment below is reversed, and the petition is directed to be dismissed.
