Opinion by

Appellant commenced wrongful death and survival-actions against appellee and Keta Gas & Oil Company, Inc., which actions resulted in a jury verdict for appellee, Keta Gas having obtained judgment in its favor prior to trial. This appeal followed the refusal of appellant’s motion for new trial and entry of judgment on the verdict.

Harold Stuck, an employee of the Keta Gas & Oil Company, Inc., was killed when struck on the head by *541a device known as a gin pole.1 The accident occurred on July 26, 1956, in Armstrong Township, Indiana County. At the time of the accident, Harold Stuck was helping to unload two A-frames2 which were made of heavy steel and had four sides. These A-frames weighed from eight to ten thousand pounds, and were about thirty-five feet long, and approximately four and one-half feet by six to six and one-half feet wide. The two A-frames had been chained together for the purpose of transportation by the appellee, Charles O. Ingmire, a heavy equipment hauler. The A-frames were transported to the site for the drilling of a gas well. An employee of appellee had driven a tractor and a flat bed trailer on which the two A-frames were chained together to the drilling site and the trailer was stopped near the substructure of the drilling apparatus which was in the process of being erected.

Shortly after the arrival of the tractor and trailer bearing the A-frames, another employee of appellee backed a flat bed winch or hoisting truck to a point about three feet from the center of the A-frames and at right angles with the left side of the A-frames as carried on the trailer.

Harold Stuck had been working on the substructure and stepped from it onto the A-frames to help with the unloading of the A-frames. While Harold Stuck was on the A-frames, the chain was unfastened and a winch line from the hoist truck was fastened around the A-frame nearest the hoisting truck. After the winch line was fastened to the A-frame, an attempt was made to lift it. This was unsuccessful because as soon as an *542attempt was made to lift the frame, it caught on the “gin pole”. After the unsuccessful attempt to lift the frame, Harold Stuck loosened the winch line and dropped the chains onto the back of the winch truck' and it was hooked back on the truck, and the slack in the winch line was taken up. The frame tumbled, striking the gin pole with such force as to' cause the safety chain, which was intended to keep the gin pole in position, to break. The gin pole snapped back, toward-the winch machinery on the front part of the truck near the cab, known as the “headache”, striking Harold Stuck on the head, killing him instantly. It is not known nor was it explained how the decedent got to the position he was in on the winch truck when struck by the gin pole. Nor does the evidence reveal what-caused the frame to tumble.

Appellant’s contention is that Harold Stuck got on the back of the winch truck and it started to move and the winch line must have been wrapped around part of the A-frame which caused the A-frame to fall. If there, was any proof or circumstances proved from which an inference could be drawn that such* event did .occur, it would be a question for the jury. There is, however, no such proof, but rather, the evidence shows that such was not the fact. Nevertheless, the trial judge submitted the case to the jury. There was a great deal of testimony which was all to the effect that an accident-occurred but no evidence was produced which would' allow even an inference of what caused the accident.. There was not sufficient evidence to warrant the submission of this case to the jury. The trial judge recognized this when, in his opinion sur motion for new trial, he said: “Possibly the court in this case should have refused to have allowed this case to have gone to the jury”, and: “Whether or not there was such evidence was left to the jury and this court feels that the verdict of the jury was based on the evidence and *543was proper and in fact this would have been a case where it is possible had the plaintiff recovered, serious .consideration would have been given for a motion for judgment n.o.v.”.

Appellant urges several reasons for a new trial. It is unnecessary for us to consider any of them in the light of this record which is devoid óf any évidence of negligence on the part of appellee.

Judgment affirmed.
