Opinion

Mr. Presiding Justice Baldwin

delivered the opinion of the court.

This is an appeal from a judgment for $2,500 upon a verdict for that amount entered in the Circuit Court of Cook county, in favor of appellee and against appellant. Appellee, a boilermaker, was operating a horizontal punch in the shop of appellant in South Chicago, and on the 12th day of April, 1909, was struck by a flying particle of steel, by which the sight of one eye was destroyed. At the time of the accident, appellee had been working as a boilermaker in appellant’s plant for about fourteen months, and in the same capacity for other companies for about nine years, previous to which time he had been an apprentice in the boilermaking’ business for about three years. He had become proficient in the various branches of the boilermaking business, including the use of machines designed for punching holes in boiler plate. The machine in use by him at the time of the accident was one known as a horizontal punch, and it had been in constant use at that place during the entire term of appellee’s employment there, and for several years previously. It was a heavy machine, operated with electric power, and capable of punching cold boiler plate one inch thick.' Near one end of it was a rectangular notch or “throat” some eight inches deep and four or five inches wide, extending transversely across the top; in one of the perpendicular sides of this throat was set a heavy casting, known as the “tail stock,” sometimes called “die block,” or “die holder,” which had in it a round hole about one inch deep and two inches in diameter. The die was cylindrical in shape, about one inch long, having a circular hole extending entirely through it, and was placed in the hole in the tail stock. Directly opposite the die and tail stock, in the other side of the throat, was the punch stem and the mechanism operating it. The machine was very powerful, the punch being capable of striking a blow of seventy tons. Between the two sides of the throat was the “stripper,” an upright piece of iron or steel with a U-shaped opening through which the punch passed when in motion, its purpose being to remove from the punch, on its backward motion, any metal which might cling to it after the hole had been made. When in proper alignment, the punch stem would penetrate the metal to be punched, enter the hole in the center of the die, and force the piece of metal punched out ahead of it through the hole in the tail stock to the back of the machine. There was a small handwheel at the side of the machine, by means of which the punch could be slowly moved into the die; this was used to determine whether or not the die was in proper alignment. The dies were all made in the shop and were from 1-16 to 1-8 inch less in diameter than the hole in the tail stock; they were made this way so as to allow an adjustment of the die with reference to the point where the punch would strike. This adjustment was accomplished by wrapping pieces of tin or sheet iron (called ‘‘ shims ’ ’ or “liners”) around the die to the required thickness, and then driving the die, with these shims, into the hole in the tail stock. These shims served the double purpose of holding the die tight in its socket, and of properly aligning it with the punch. This method of setting the die had been in use during the entire term of appellee’s employment, and for eight or ten years previously. After inserting the die, with the shims around it, in the tail stock, the operator would test the machine with the handwheel. If the punch stem entered the hole in the die squarely and the die was tight in the socket, the punch was ready for use. It was set in motion by pressing a foot-pedal at the base of the machine.

On the day of the accident, appellee was punching holes in the flange of a nozzle. The nozzle was a large pipe six feet in diameter and about six feet long, made of % inch boiler steel. One end was cut out so as to fit against the side of a circular tank and a flange turned on the edges. Appellee, at the time of the accident, was punching rivet holes in this flange and also trimming off the edges. This large pipe weighed several hundred pounds, and was supported from above by a traveling crane- and chain hoist. Appellee had two helpers who acted under his instructions in shifting the nozzle and adjusting it in position. During his employment with appellant, appellee had punched at least two such nozzles on the machine as well as some angle irons; each of these operations requiring the use of the punch several hours. Though he had never used a horizontal punch, like this one, until employed by appellant, he had observed them while working in at least two other shops, and had frequently operated vertical punches before working for appellant, having begun to use them some ten years before the accident. The punches and dies, which he had used in these vertical punches, were all of tool steel and of the same general structure as the punch stem and die on the machine in question. He had also used the other horizontal machine in appellant’s shop two or three times before the accident.

Shortly before ten o’clock on the day he was injured, after having marked the places for the rivet holes by making dents with a hand-punch in the flange, and having marked off the edges which had to be cut off, he told the foreman of the shop that he had the job ready; the foreman then told him, “go take it over to that punch and punch it.” The work was hanging on the overhead hoist, and the die was already set; he tried the punch with the handwheel, and, finding it right, began his work. The method of working the machine was to first move the punch up with the handwheel until the small point in the center of the punch struck the dent previously made in the flange to indicate the center of the hole; then press the pedal at the base; this turned on the power and the punch would immediately pass through the metal and return to position. The nozzle would then be shifted so as to have the next dent in line with the punch, and the operation repeated. When punching rivet holes, which were about two and one-half inches apart, it was generally necessary to shift the nozzle before each punch. The same machine was also used for cutting off the surplus edge of the flange.

On the day of the accident, appellee’s method was first to punch two or three rivet holes, then cut off the surplus edge opposite. With the exception of twenty-five minutes had for dinner, he worked on the punch

_\_ steadily from ten o’clock in the morning until three o ’clock in the afternoon. In that interval of four and one-half hours, the die came loose once or twice, when he put the shims back in place again and continued the work.

It appeared further that he put his hand on the die ten or twelve times to see whether it was securely in place, as he found it had a tendency to become loose when used by reason of the fact that a portion of the metal forced into the die ahead of the punch would sometimes get wedged between the outside of the punch stem and the inside of the die so that when the punch drew back it would pull the die with it.

At the time of the accident, appellee was punching the surplus edge off, and, instead of stopping the machine after each punch, he kept the punch going at the rate of about forty strokes a minute by retaining his foot on the pedal. Suddenly something struck him in the eye. He let go of the material, looked at the die and found that it had become loose and tipped a little.
