On and prior to October 10, 1891, the date of the written contract between the plaintiff, as party of the first part, and the defendants, as parties of the second part, botli parties were engaged in the manufacture of center plates for ear trucks under, patents owned by them respectively; the plaintiff at Chicago, III., and the defendants at Pittsburgh, Pa. By the terms of the contract the plaintiff granted to the defendants the exclusive right to make center plates under the plaintiff’s patents, and the defendants agreed to pay to the plaintiff per centum of the gross selling price of all center plates sold by them; and it was Stipulated that the plaintiff should hav-e the right to make center plates “for application to pressed metal truck frames manufactured by it” upon the payment, of a named royalty but should not otherwise engage
“It is further agreed that the parties of the second part will not engage, during the life of this agreement, in the manufacture of truck frames for moving vehicles, ■or any part of such frames, when made of pressed metal.”
The present controversy grows out of a difference between the parties as to the meaning of this clause. The plaintiff contends that the clause prohibits the defendants not only from making pressed metal truck frames and parts of such frames, but also from making out of pressed metal any part of a truck frame, of whatsoever kind the truck frame may be. The defendants maintain that the prohibition is against the making of pressed metal truck frames and parts of a pressed metal truck frame. If the literal reading of the clause were determining, the plaintiff’s construction might be entitled to preference. But in the interpretation of a particular clause of a contract the court is required to examine the entire instrument, and may also consider the relations of the parties, their connection with the subject-matter of the contract, and the circumstances under which it was made.

Upon the question of the proper construction of this clause, my opinion, under all the circumstances of the case, accords with the view upon which the defendants insist. But finally, if, as the plaintiff contends, this clause really interdicts the defendants’ manufacture out of pressed metal of any part of a diamond truck frame, then the clause, in my judgment, is in unreasonable restraint of trade, and not enforceable.
