delivered the opinion of the court:
The questions arising on this record are on the motion of appellee to exclude the evidence and instruct the jury to find for the defendant, on instructions given for appellee, and thé modification of instructions asked by appellant.
It is the duty of the company to exercise reasonable and ordinary care and diligence in providing and keeping in repair reasonably safe machinery and appliances for the use of its servants; and this is a continuing duty, requiring the company to exercise reasonable diligence and care in supervision and inspection. The delegation of that duty to an employee does not relieve the company from liability because of the negligence of that employee in- the discharge of that duty. Chicago, Burlington and Quincy Railroad Co. v. Avery, 109 Ill. 314 ; Chicago and Northwestern Railway Co. v. Jackson, 55 id. 492; Same v. Swett, Admr. 45 id. 197.
The duties of George H. Kneirim, as a helper in the yards, were to catch and couple cars. A train coming into the yards is checked up on the switch list, with each car number put down opposite the destination of the car. The foreman in charge of the yard engine takes the list, cuts off the cars and places them on the different tracks *462for the purpose of making up the several trains or transferring to another road. The helpers, in catching the cars, climb on and set the brakes, and when making up the train couple the- cars. The helper would mount the car when in motion, by the direction of the foreman, or, when knowing his duties, without direction from any one. It also appears from the evidence that a train coming into the yards where Kneirim was injured, would be left by the train crew that brought it in, and there be examined by the inspectors employed for that purpose, their duty being, to inspect the train before the yard engine cuts the train up. By that inspection they were to examine all the cars, to see if they were in proper condition for running, and, if any of the machinery and appliances were out1 of repair, to fix the same, but if unable to fix them, to mark the car with chalk over its number, and it was then to be sent to the shops. The inspectors who examined this train did not inspect the brake-staff of the car, because of the imperfect and unsafe condition of which plaintiff was injured. The evidence shows that the nut which held the wheel on the brake-staff was off, and, from the rusted appearance of the threads on the staff,—they being filled with rust,—had been off for several weeks. Kneirim, who was on duty as a helper, and in the night time, when this car was cut from the train and sent back on the switch, mounted the car while it was in motion, and after it had run several car lengths set the brake, and the wheel coming off of the brake-staff caused him to fall and be run over, so injuring- him that death soon resulted.
It is insisted that Kneirim assumed the ordinary hazards of his employment, and was required to use reasonable care and caution for his own safety, and should have examined the brake to assure himself it was in a proper condition of repair. Whilst Kneirim assumed the ordinary dangers and risks of his employment, he did not assume a risk of the negligence of the employer in failing *463to have the cars and appliances in a reasonably safe condition. He had a right to believe the cars were, as to their repair, in a reasonably safe state, and that the master’s duty in that regard had been discharged. They had just passed an inspection by men employed for that purpose. His duties required him to act promptly, and it cannot be expected or required that he should act with the deliberation and circumspection that could be exercised by the inspectors. He could not, from the nature of the duties he discharged, be expected to examine the brake-rod ag to whether there was a loss of a nut, that caused it to become unsafe. The car had not been under his supervision or control. He had no former care of it. It passed him, and whilst in motion his duties required him to mount it and set the brake. He was not, and could not be, responsible for the defect, nor could he be held guilty of contributory negligence in failing to examine the brake-rod, wheel and nut, under the circumstances. Chicago and Northwestern Railway Co. v. Jackson, 55 Ill. 492.
The case of a helper in a switch yard is unlike the case of a brakeman on a freight train, whose most important duty is the management of the brakes, and whose duties bring him in contact with the train such a length of time that it becomes his reasonable duty to see whether the brakes are in order, as held in Chicago and Alton Railroad Co. v. Bragonier, Admx. 119 Ill. 51, and in Illinois Central Railroad Co. v. Jewell, Admx. 46 id. 99. In the latter case it was held: “The condition of the brake was a matter under the special- care of the brakeman, and it was his business, at all times, to see that it was in a fit condition for use, and report defects to the company.” The jar of a train in motion having a tendency to cause the nuts to loosen and come off, the brakeman is required to' be constant and watchful as to the condition of the brakes. Where a car is sent out immediately after inspection, and in an unsafe condition of repair, and injury results from *464such cause and under such conditions, a case would be presented, as to brakemen, that is not included in the Bragonier case and in the Jewell case, supra.
It is next urged that the injury resulted to Kneirim through the negligence of a fellow-servant. The claim is, that the brakeman who brought the train to the yards was charged by law with the duty of ascertaining that the brake was in order, and report any defects to the proper person, that they might be remedied, and the car inspectors were charged with a like duty; that Kneirim was frequently handling cars coming from such brakeman and passing such inspection. The master’s duty of supervision and inspection is one that cannot be delegated so as to relieve the master of liability. Whilst a corporation must act through its servants, yet when such servants are entrusted with a duty that belongs to the principal as a primary duty, the negligence of the servant entrusted with that duty is negligence for which the principal is liable. The corporation can only see, examine and determine the condition of repair in which a car may be, by its inspectors. That duty must be exercised with the same degree of diligence by such employees as is imposed on a natural person who may be the master. Whether the brakeman and the helper were engaged in a distinct and wholly different business, and whether a relation existed between them by which one might exercise any influence on the other promotive of proper caution, are questions of fact, as is also the question of the relation of this helper to the train crew with which the brakeman served, who brought the train into the yards and there left it in charge of the inspectors. Not until the latter had made their inspection was the train in charge of the foreman of the yards to be broken up for the purpose of making up other trains, and only after inspection was the work of the switch engine and helper brought into requisition. Whether the helper, under such circumstances, is a fellow-servant of the brakeman who brought the train *465into the yards, or of the inspectors, is to be passed on by the jury, and it was not error to refuse to instruct the jury to find for the defendant.
Error is assigned in giving instructions for. appellee. The first instruction given for appellee correctly stated the duty of the appellant as to furnishing reasonably safe machinery and appliances, and its duty to exercise reasonable diligence, care and skill in keeping the same in repair. The second instruction given for the appellee was:
“It is the duty of a railroad company to provide car inspectors to inspect their cars and trains and machinery, and to see that the same are in proper repair; and if a brakeman in the employ of a company, while in the exercise of due care and caution for his own safety, should receive an injury on account of the negligence or carelessness of such car inspector in not noticing and reporting defects in the machinery, then and in that case such company would be liable to the parties .injured for such injury, unless you believe, from the evidence, they were fellow-servants in the same line of employment, as defined in these instructions.”
The negligence charged in the declaration was : “The plaintiff avers that the defendant then and there carelessly and negligently failed to have said wheel properly and securely fastened upon said brake-staff, so that the same would not come off when a brakeman, in the use of said wheel, attempted to set said brake, and by reason of said wheel not being properly and securely fastened, and the negligence and carelessness of the said defendant, as aforesaid, said Kneirim was thrown upon the tracks, injured and killed.” The negligence charged was in failing to have the brake-wheel securely fastened upon the brake-staff, etc. By the second instruction the jury are told that it is the duty of the company to provide car inspectors, and if a brakeman receives an injury because of the negligence of the inspectors in not noticing and
*466reporting defects, the company would be liable. The attention of the jury should have been directed to the negligence charged in the declaration, and not to the negligence of the inspectors in failing to notice defects. The instruction was improper. The cause of the injury was shown to have been the defective fastening of the wheel to the brake-staff.
Appellant excepted to the giving of the third instruction for appellee and the modification of the fifth instruction asked by the appellant. The questions raised in these two instructions may be considered together.
The third instruction given for appellee, to which objection is made, is as to the definition of fellow-servants, as, they “must be such as are engaged in the same line of employment, and whose duties bring them into habitual association with each other, so that they may exert a material influence upon each other promotive of proper caution.” The fifth asked by the appellant was modified so as to state, if “they were engaged in the same general line of business, directly co-operating with each other in the particular business, and that their duties were such as to bring them into contact and habitual association with each other in such a manner that they would exercise upon each other a mutual influence pro-motive of proper caution.”
The rule in this State is, that where one servant is injured by the negligence of another servant, where they are directly co-operating with each other in a particular business in the same line of employment, or their duties being such as to bring them into habitual association, so that they may exercise a mutual influence upon each other pro-motive of proper caution, and the master is guilty of no negligence in employing the servant causing the injury, the master is not liable. Chicago and Northwestern Railroad Co. v. Moranda, 93 Ill. 302; Stafford v. Chicago, Burlington and Quincy Railroad Co. 114 id. 244; Chicago and Eastern Illinois Railroad Co. v. Geary, 110 id. 383 ; North Chicago Rolling Mill *467 Co. v. Johnson, 114 id. 57 ; Chicago and Northwestern Railway Co. v. Snyder, 117 id. 376; Same v. Same, 128 id. 655 ; Chicago and Alton Railroad Co. v. Hoyt, 122 id. 369; Chicago and Northwestern Railway Co. v. Moranda, 108 id. 576; Chicago and Alton Railroad Co. v. Kelly, 127 id. 637 ; Joliet Steel Co. v. Shields, 134 id. 209.
These instructions, as given and modified, did not correctly state the rule as to the relations of fellow-servants. Servants may be directly co-operating with each other in a particular business, in the same line of employment, and yet not be such that their duties bring them into habitual association, so that they may exercise a mutual influence on each other promotive of proper caution. These clauses should have been connected by the disjunctive “or” instead of the conjunctive “and.” The error, however, in the second and third given for appellee, and the modification of the fifth asked by appellant, when the facts were made so prominent by the evidence as appears in this record, could not have misled the jury to the prejudice of the appellant. The duties of the car inspectors and of the helper were clearly shown by the evidence. Their relation to each other depended on evidence which was clear and explicit. The proximate cause of the injury could not have been misunderstood, and the error in the instructions, under the facts in this case, could not have prejudiced the appellant. Whilst this court is bound by the finding of facts as made by the Appellate Court," it yet becomes the duty of this court to look into the evidence in the record in determining the correctness of instructions based on the facts of a case. Where this duty, thus imposed, is discharged by this court, and from the evidence it appears that no other verdict than that rendered could have been properly returned by the jury under instructions entirely correct, we are not required to reverse a judgment because "of errors in instructions.
*468The fourth instruction given for appellee- -was, if the jury should find for the appellee they should assess the damage at whatever sum they “should deem just and reasonable, from all the evidence in the case, not- exceeding the amount claimed in the declaration.” The declaration alleges pecuniary loss by reason of the death of the husband and father, who, in his lifetime, was in receipt of a certain sum for his wages and services, which ivas used in the maintenance and support of his wife and children. The instruction referring to the declaration could not have been understood by the jury to have authorized damage to be assessed by way of solatium, for there is no claim for such damage made in the declaration. The objection made to the fifth instruction given for the appellee is not tenable.
Prom a careful examination of the record we find no reversible error in the judgment of the Appellate Court, and that judgment is affirmed.
Judgment affirmed.
