Opinion

*136 Dell, Chief Justice.

Defendant appeals from an order denying its motion for judgment notwithstanding the verdict or in the alternative for a new trial.

The action arises out of an alleged breach of contract between the plaintiff, a designer and manufacturer of production machines, and defendant, a manufacturer of conveyor systems, for the sale of a reciprocating bearing assembly machine. Late in 1952 plaintiff learned that defendant was in the market for a new machine to assemble ball bearings and he solicited the appropriate officers of defendant to secure the business. At that time defendant was using what was known in the trade as a rotary turntable to assemble the bearings. Component parts of the bearings were put together by hand on an assembly-line basis. After each employee had performed her operation the table was advanced forward one notch. When the bearing was completely assembled and while still on the rotary table it would move under a punch press for final clinching. A two-step operation was performed by the press. The edges of the outside shell were first partially crimped and then the press hit the bearing a second time and completely sealed it. The principal objections to the rotary table were its limited output (approximately 20 to 23 bearings a minute) and its tendency to move, start, and stop with a jerk, often causing the balls to spill out of the partially assembled bearings.

After numerous discussions between the parties, it was agreed that defendant’s needs could best be served by a machine with a constantly moving transfer device, the acceleration of which could be hydraulically controlled. The contract was embodied in defendant’s written purchase order of March 4, 1953, and plaintiff’s letter of acceptance of March 7. The purchase order called for a machine 9 feet long which could be attached to defendant’s existing punch press and which would be suitable for assembling 45 bearings a minute without spilling balls or other parts. Plans were to be submitted within 30 days and the machine was to be completed within 90 days after the plans were approved. The machine was to operate continually instead of stopping for each operation and the only stoppage was to be by pushbutton or by action of a detector which indicated that extra parts were in the bearing. The purchase price was $6,500, of which 10 percent or $650 was *137 enclosed with the order; another 10 percent was to be paid upon approval of the blueprints; and the balance was “to become due 30 days after the machine is operating to our [defendant’s] satisfaction.” Plaintiff was to supervise the installation but the work itself was to be done by defendant’s employees.

Some modifications were provided by plaintiff’s letter of acceptance. The time for submitting plans and for final delivery was extended to 60 and 120 days respectively. The stoppage function of the machine was amplified to include improperly completed bearings, those which were not properly located on the table, and those with an incorrect ball count. A suggestion was made to decrease the length of the machine to 8 feet but this was rejected. It is not clear how many employees were to be located around the machine. There is no doubt that at least six were contemplated. The purchase order speaks of a “suitable length to accommodate three operators on each side.” Whether a seventh person was to be seated at the end is questionable. Defendant’s order does not mention it, but plaintiff’s letter of acceptance refers to “three operators on each side with one on the end.” The final paragraph of plaintiff’s letter is as follows:

“The above machine is to remain my property until paid in full. If it cannot be made to operate to your satisfaction, I will take it out and refund any money you have paid me on it. This to be the full extent of my liability.”

Plaintiff made several trips to defendant’s plant and thoroughly inspected it before he drew up and submitted the blueprints of the machine to the defendant. The plans were approved by defendant, another $650 was paid to the plaintiff, and he began to construct the machine. By the fall of 1953 the machine had been built and plaintiff requested some of defendant’s officers to visit his shop in order to watch a trial run. This turned out to be unsuccessful and certain adjustments had to be made. When these were completed, the machinp. was picked up by defendant and delivered to its plant on October 24, 1953. A 3-week delay in the installation was occasioned by a strike. Thereafter defendant proceeded to install the machine without plaintiff’s supervision. Due to an oversight, the wrong schematic diagram of the *138 machine’s electrical wiring was sent to defendant’s plant and one of the men there attempted to rewire it to that diagram. Further changes were required to accommodate the machine to the punch press because of the former’s height. After these had been made the new machine was attached to the punch press but the two failed to work together. Plaintiff’s machine was removed and he was notified. Subsequently a correct schematic diagram was produced and plaintiff rewired the machine as it was originally designed. It was again attached to the punch press — this time under plaintiff’s supervision — and another “dry run” was conducted on a Saturday in December 1953. This was successful and the machine was scheduled to go into production the following Monday morning.

On Monday morning the machine again failed to work and plaintiff was summoned. This time he diagnosed the trouble as insufficient air pressure. Although the written contract was silent in that regard, plaintiff claimed that defendant had promised to provide the machine with 100 pounds of pressure per square inch but that was denied, the boiler inspector having forbidden defendant to use more than 85 pounds of pressure per inch for safety reasons. Although the machine ran successfully during the trial the preceding Saturday while the plant’s other machinery was idle, on Monday the other machinery in the plant also put a drain upon the supply of air so that at times the pressure on this machine dropped as low as 45 pounds per inch. A larger air cylinder was needed which would operate on fewer pounds of pressure and plaintiff agreed to design and build one, which he did. The new cylinder was attached to the machine in January 1954 and the machine was again connected to the punch press. This time it did not work satisfactorily either and plaintiff then complained that it was because defective parts were being used in the bearings. It appears that occasionally one of the parts which fit just inside the outside shell of the bearing was not perfectly round and could not be dropped into place. This required that the part be hammered into the outside shell and during this period a defective bearing or no bearing at all might pass by the detector which would cause the machine to stop. Problems concerning synchronization also arose. In any event plaintiff admitted that his machine did not work properly while attached to the old punch *139 press and it was disconnected in February awaiting a new punch press which was installed on June 11, 1954.

Plaintiff’s records showed that he did not visit defendant’s plant between February and August 1954 when he came to get a schematic diagram of the wiring of the new punch press.
