This is an action of contract to recover on an automobile liability policy. The alleged liability of the defendant arose out of an automobile accident in which four persons, the plaintiffs in the original actions against Lunt, were injured. They recovered verdicts. This action was then brought to recover on the policy. It provided that the insurer shall not be liable for “Accidents to any other employee of the Assured arising out of or in the usual course of the trade, business, profession or occupation of the Assured.” When the case previously was before this court, Lunt v. Aetna Life Ins. Co. 253 Mass. 610, it was decided, that, as the quoted words were incorporated in the general clause of the policy, it was essential for the plaintiff to negative them. The plaintiff amended his declaration and the case went to trial in the Superior Court. A verdict was ordered for the defendant, and the plaintiff excepted.
The plaintiff in the case now before us contends that the defendant, by assuming the defence of the original actions, is estopped to deny that the accident to the plaintiffs in those actions was covered by the policy. The policy provided that, “If suit is brought against the Assured to enforce a claim for damages covered by the policy . . . the Company will, at its own cost, defend such suit in the name and on behalf of the Assured.” It was agreed that Charles C. Milton, Esquire, and F. L. Riley, Esquire, took part in the trial of ' the original cases against Lunt, and in so doing acted for the Aetna Life Insurance Company and were paid by it for their services; that Mr. Milton, who opened the cases, examined and cross-examined the witnesses and argued the cases on behalf of Lunt; that Lunt was personally represented at the trial by two attorneys, Mr. Hastings and Mr. Young, both of whom were in court during the entire time of the original actions.
As we construe the policy, the insurance company was not obliged to defend actions not covered by the policy. Its undertaking in this respect was limited to the defence of actions brought against the insured for actions which were covered by the policy.
It has been held that where an insurance company takes *473control of the proceedings in an action brought against the assured, it is thereby estopped to say that the liability claimed is not within the terms of the contract. Tozer v. Ocean Accident & Guarantee Corp. Ltd. 94 Minn. 478. Patterson v. Adan, 119 Minn. 308.
At the trial of the original actions, the defendant was represented by his own counsel. He had every opportunity to protect his interests and was not injured by the acts of the insurance company. Although counsel for the insurance company tried the cases, the assured was not prevented from securing all his rights, and there is no evidence that the insurance company acted adversely to his interests. “In order to work an estoppel it must appear that one has been induced by the conduct of another to do something different from what otherwise would have been done and which has resulted to his harm and that the other knew or had reasonable cause to know that such consequence might follow. . . . ' The law does not regard estoppels with favor, or extend them beyond the requirements of the transactions in which they originate.'” Boston & Albany Railroad v. Reardon, 226 Mass. 286, 291. Rollins v. Bay View Auto Parts Co. 239 Mass. 414, 420-422. Applying this rule to the facts shown on the record, the assured was not misled by the conduct of the insurer; he was not induced to do anything different from what he otherwise would have done, and there is no evidence of any harm resulting to him from the conduct of the insurance company. Therefore, the insurance company was not estopped from contending that the accident from which the original actions arose was not covered by the policy.
The policy provided that the insurance company was not to be held liable for “Accidents to any other employee of the Assured arising out of or in the usual course of the trade, business, profession or occupation.” In the trial of the original actions this question was submitted to the jury: “At the time of the accident in question was the said . . . [plaintiff in each of the original actions] in the employment of the defendant Joseph H. Lunt?55 The answer was “Yes.55 It is now contended by the insurance company that the *474plaintiff in the present action is precluded by these answers and cannot rightly contend that the injured persons were not his employees. In the action before us Lunt seeks to recover on the insurance policy. The original actions were against Lunt for negligence in operating his automobile. The insurer was not a party to these actions. Lunt and the insurance company were not adverse parties. The principle of res judicata has no application. The proceedings were not between the same parties or their privies. The causes of action were not the same and the rights now involved were not adjudicated in the original actions. McCarthy v. William H. Wood Lumber Co. 219 Mass. 566. McAlevey v. Litch, 234 Mass. 440.
The principle of estoppel by judgment or verdict has no application. General verdicts were returned in the original actions, and it is not shown on what ground the verdicts were rendered. It does not appear that the answer of the jury was essential in the cases, nor that the question whether the plaintiffs were employees of Lunt was involved in the controversies. See Freeman on Judgments (5th Ed.), § 692; Burlen v. Shannon, 99 Mass. 200. The cases of Boston v. Worthington, 10 Gray, 496, and Boston & Maine Railroad v. T. Stuart & Son Co. 236 Mass. 98, relied on by the defendant, do not sustain its contention.
Although the assured was not precluded by the answer of the jury in the original actions, the burden was on him to show that the accident was within the terms of the policy. The policy gave him no protection if the accident happened to his employees “arising out of or in the usual course of the trade, business, profession or occupation of the Assured.” He could not recover unless there was evidence that the injured parties were not his employees, injured because of such an accident. Lunt v. Aetna Life Ins. Co., supra. There was evidence tending to show that the trade, occupation or business of Lunt was that of catering; that he catered at fairs and other entertainments and at times conducted “clambakes.” It appeared that the four plaintiffs in the original actions were injured on June 3, 1921, while riding in Lunt’s automobile on the way to the fair grounds, Wor*475cester, where the Commercial Travelers Association was to have a dinner; that the automobile was driven by his servant; that Lunt was “Superintending, getting the dinner together . . . superintending the luncheon”; that on the day preceding June 3, the plaintiff asked two of the original plaintiffs “if they could get some help for the following day”; that he agreed to meet them at Lincoln Square and convey them to the fair grounds; and that in accordance with his request, additional help was secured. It also appeared that Lunt was a member of the Commercial Travelers Association and a member of the luncheon committee; that he “received no pay for his services” in connection with the dinner; that he bought supplies for the entertainment, but did not pay the plaintiffs; that some of his equipment was in use at the dinner. To show that the original plaintiffs were not his employees, injured in an accident “arising out of or in the usual course of the trade, business, profession or occupation,” he made an offer of proof to the effect that the expenses of the dinner were borne by the association, that “he didn’t cater for the dinner,” that one Whiting had charge and had been furnished with funds “to pay the help.”
The plaintiff had a right to show that the injured plaintiffs were not his employees and for this purpose could offer any competent evidence. He could show what the real arrangements were. If, as a member of the luncheon committee and acting gratuitously, he secured the services of the original plaintiffs to work for the association as its servants, the jury could have found that the injured parties were not employees of Lunt. Standing alone, the evidence offered was not sufficient to support this contention; but in connection with the other evidence in the case and other offers of proof, we think it was competent for the purpose for which it was offered. There was evidence from one Coleman, not a member of the association, that he was asked by Whiting to check up the time of the employees and incoming supplies; that he had the names of the injured plaintiffs on his list. The plaintiff testified “he received no pay for his services in connection with the dinner”; that he ordered supplies, but received no bill, and in this connection offered to show that *476these supplies were charged to the association and “so billed.” He also testified that he paid none of the people who worked at the dinner and did not pay the plaintiffs in the original actions. He also offered to show that Coleman had in his hands the sum of $500 given him by the executive committee of the association “to pay the help.” Taken in connection with the evidence already admitted and the additional evidence offered and excluded, the offer of proof to the effect “that he didn’t cater for the dinner” and that Whiting had charge of the arrangements was competent. It tended to show that Lunt, in whatever he did for the success of the entertainment, was not following his trade, occupation or business, but was acting gratuitously as a member of the association, and that the injured parties were not in fact his employees but were employees of the association. See in this connection Bingham v. Scott, 177 Mass. 208, 211, where the meaning to be given the words “employs” and “employed” is considered. The case should have gone to the jury on this issue. We also think that the other offers referred to, bearing on this question, were competent.
As there must be a new trial of this case, we consider certain questions which are likely to arise. As has been said, the policy excluded injuries to employees of the assured from accidents arising out of or in the usual course of the trade, business, profession or occupation of the assured. The plaintiff contends that the word “or” preceding the words “in the usual course” means “and.” We do not agree with this contention. The word “or” should be given a disjunctive and not a conjunctive meaning. It is not synonymous with “and.” It is to be construed as having a different meaning from “or” and to mean “and” only when the context and the main purpose of all the words used demand this meaning. Marble v. Treasurer & Receiver General, 245 Mass. 504, 508, 509, and cases cited.
The offer of proof was not technically accurate, as it substituted “and” for “or”, but we do not understand that the defendant objected to the form of the offer, and the substance of the policy was followed. It was admissible to *477show that the plaintiffs in the original actions were not employees of Lunt.
The offer of proof was also to show “that the defendant has waived any right to contest the coverage of the policy, and is estopped to do so.” In this offer of proof, in addition to what has already been said, there was a suggestion of a settlement of the original actions. As we understand this offer, it amounts to a mere discussion of the question of settlement. It did not go far enough to show that the plaintiff was in any way injured or deprived of any of his rights. As his own counsel participated in the trial, the insurance company was not estopped and the offer of proof did not tend to establish an estoppel. The plaintiff should haye been permitted to show that the injured parties were not his employees within the meaning of the policy. The entry is to be
Exceptions sustained.
