Opinion

ROBERT L. TAYLOR, District Judge.

This case was transferred to this court by the United States District Court for the Eastern District of Pennsylvania, under Title 28, U.S.Code, § 1404(a), for the convenience of the parties and the witnesses.

Plaintiff is a Pennsylvania corporation and the defendant a Maryland corporation. The amount in controversy is in excess of $10,000.

The incident that caused the damages that are the subject of the suit occurred in Tennessee on April 11, 1956. The Boiler and Machinery insurance policy which plaintiff claims covered the losses was issued and delivered by the defendant in Tennessee on January 5, 1955. Electro Manganese Corporation, of Knoxville, Tennessee, was the original named assured. By Endorsement No. 9 dated March 16, 1956, Item No. 1 of the policy was amended to read “Foote Mineral Company,” said company having previously purchased all of the assets of the Electro Manganese Corporation.

The policy is described as a Boiler and Machinery Policy which insured plaintiff against loss by accident of objects described in detail in schedules 1 and 2 and the amendments thereto.

Schedule No. 1 is entitled “Electrical Machines.” The items insured were divided into groups. Group No. 1 insured “Electrical Generators of 50 kw or larger and Electric Generators used as Exciters.” One of these generators, which was a 1500-kilowatt Westinghouse, was greatly damaged as a result of an explosion while its commutator was being ground on April 11, 1956, by a representative of the Westinghouse Electric Corporation of Atlanta, Georgia.

Group No. 2 of Schedule No. 1 insured “F’ectric Motors of 70 h. p. or larger.” One of the motors described in this group, and the one which was attached to the damaged generator, was completely destroyed by fire at the time of the incident which caused damage to the generator.

The original complaint sought to recover damages in the amount of $34,101.-15 for injuries to the generator and motor, but after a fire insurance company paid plaintiff the sum of $14,453.06 [927]*927damages for the loss of the motor, the claim under this item was reduced to $19,648.09.

The policy also insured against loss for partial prevention of business caused by accident under what is termed the “Use and Occupancy” endorsement. This item amounted to $56,790.67.

There is no dispute as to the amount of damages sustained by plaintiff as a result of the accident. Counsel for the defendant stipulated during the trial that the generator was damaged in the sum of $19,648.09 and that the damage caused by partial prevention of business while the generator was being replaced was $56,790.67.

The insuring agreement provides, in pertinent part, as follows:

“In consideration of the Premium, the Company agrees with the Assured respecting loss from an Accident, as defined herein, occurring during the Policy Period, to an Object, as defined herein, while the Object is in use or connected ready for use * * *.” (Emphasis supplied.)

Defendant contends that the generator was not in use or connected ready for use at the time of the incident causing the damage, and that it is not liable to the plaintiff for the loss. Plaintiff contends that the generator was in use or at least connected ready for use at the time of the accident and that the loss was covered by the policy.

Special Provision D(a), under Schedule No. 1, provides:

“The Company shall not be liable for loss from an Accident to any Object which is designated and described in this Schedule while said Object is undergoing an insulation breakdown test, or is being repaired or dried out.” (Emphasis supplied.)

Defendant further contends that it is not liable to plaintiff for the damages to the generator because it was being repaired at the time of the incident causing the damages. Plaintiff contends that the work being done on the generator at the time of the accident was preventive maintenance and that the foregoing exclusion does not prevent recovery.

The policy definition of an accident is as follows:

“C. As respects any Object which is designated in this Schedule, ‘Accident’ shall mean
“1. A sudden and accidental breaking of the Object, or any part thereof into two or more separate parts, but not the breaking of any shear pin, safety link, vacuum tube, gas tube, fuse, brush or insulation, nor the loosening of any assembled parts;
“2. A sudden and accidental burning out of the Object, or any part thereof, but not the burning out of insulation unless accompanied by a short-circuit, or of any vacuum tube, gas tube, fuse or brush; or
“3. A sudden and accidental deforming of any shaft of the Object, not caused by the cracking of such shaft.”

A description of the generator on which the work was being done at the time of the accident and a detailed explanation of such work, will be helpful to an understanding of the problems that are under consideration.

A schematic drawing showing the component parts of a generator similar to the one involved in the accident is. filed in the record.

The generator consisted of a number of enclosed coils of copper wire called the armature, which armature was attached to a shaft and revolved on that shaft in a magnetic field produced by magnets which surrounded the armature with the magnets being held in place by the outside plate of the generator. On the same shaft and immediately adjacent to the armature was a circular metal ring made in segments, which segmatic ring is known as a commutator. The segments, or commutator bars, were connected with the ends of the coils of copper wire composing the armature. [928]*928Brushes made of carbon and held by brush holders pressed against the commutator. The function of the brush holders was to hold the carbon brushes in position at the correct angle against the commutator and to maintain the necessary brush pressure on the commutator. The shaft to which was attached both the armature and commutator was coupled to a motor which caused the shaft to rotate and the armature fixed to it to revolve in the magnetic field produced by the magnets surrounding the armature, and electric voltage was thereby produced. This electric voltage was then transmitted to the commutator from the coils of wire composing the armature. In the commutator the electric voltage thus transmitted to it was converted into direct current and was then transmitted from the commutator by the carbon brushes held by the brush holders.

Carbon brushes, in the process of generating electricity, press against the outer surface of the commutator causing wear and deterioration to the brushes as well as the outer surface of the commutator. The commutator surface, after prolonged use, becomes grooved, rough and scarred, uneven and pitted, and out-of-round, which if not corrected will ultimately result in a breakdown of the generator. When a scarred or roughened condition develops, it is necessary to eliminate the scars and pits and to true up the surface of the commutator, thus restoring it to a sound and good working condition. Some generators require grinding at periods of from around four to six months while others last for years. The conditions under which the generator is operated control the frequency or infrequency of the grinding periods.
