tached on two opposite sides to a trunnion a little below the perpendicular center of the ladle, so as to permit it to be turned with very little force. In fact it would not remain upright when suspended, unless held so by means of some appliance. To accomplish this, there is a gear or cogwheel firmly keyed to the ladle, and a worm attached to the bail with a clamp, held to its place by screws or bolts. The cogs or teeth of the wheel and the thread of the worm, when in position, interlock. In the proper adjustment of the apparatus is the safety of transporting the melted ir'on from the furnace to the molds. By means of a lever or crank, the worm may be turned, and thus the gear wheel is correspondingly moved, turning the ladle. In that manner, as occasion requires, the ladle may be turned and held at any angle, and restored to its upright position. A few days before the day in question the gear wheel was broken, and then a new one was put in its place. To do this, it was also necessary to loosen the clasp that held the worm to its place; and after it was repaired the ladle was taken to the cupola of the furnace, filled with 9,000 pounds of molten iron, and when it swung off it was tipped slightly, and the refuse substance on the surface of its contents skimmed off by the workman having it in charge. Then it was observed by him that the thread of the worm did not interlap with the teeth of the cogwheel. The man at the lever was unable to bring them together, and as the consequence the ladle necessarily tipped over, spilling the contents, resulting in a serious permanent injury to the plaintiff. • While the plaintiff assumed the ordinary hazards incident to the service in which he entered, the defendant owed the plaintiff the duty that he should not be subjected to perils arising from want of reasonable care in furnishing suitable or safe implements, machinery, and appliances in and pertaining to the business in which he was employed. What is reasonable cafe in a given case is dependent, more or less, upon circumstances. And the burden is with the party charging it to prove negligence. The mere fact that he has suffered injury by reason of defective machinery does not raise the presumption of negligence of the employer. Nor is the latter required to furnish the very best known appliances for the service. Nor does the master absolutely undertake for their sufficiency or safety. As has been suggested, he is in that respect required to use reasonable care, which may be defined as such care as a prudent man, having in view their suitableness and safety, would use in providing the appliances, if he personally were to be exposed to all the perils which might arise from their use in the service for which they were •designed.

142 N. Y. 31 , 36 N. E. 813 . The device of the gear wheel and worm had been in use many years in the defendant’s foundry with success, and without any accident prior to the time in question, and, so far as appears, a similar apparatus is in use in other foundries, where large castings are molded. There was nothing in the material, method of construction, or operation of it, when properly adjusted, to permit imputation of want of due
