Opinion

MORROW, Circuit Judge.

The decree here referred to is a final decree, adjudging plaintiff, the American Chain Company, Inc., the owner of letters patent No. 1,191,306, issued to Thomas A. Hoover on July 18,1916, on application filed January 24,1912, and of all rights for profits and damages by reason of past infringements thereof.

The patent relates to improvements in bumpers for vehicles, and particularly to bumpers used upon self-propelled vehicles, such as automobiles. The purpose of the invention is to absorb the shock of collision in coming in contact with another object, for example, with another vehicle.

The bumper is made of flat strip spring steel, consisting of an impact spring bar, ex-lending across the front of the automobile, substantially, from tire to tire.

The invention is described in two forms, one of which is a bumper made of a single continuous long strip of spring steel, forming the front or impact member of the bumper, with ends bent to form elongated loops and" rearwardly extending attaching arms, the ends of which are suitably attached to the side members of the automobile frame. A separate reinforcing strip is riveted to the front or body portion of the impact member. This reinforcing strip may, if desired, be made integral with the body portion in the form of a rib.

The other form of the bumper has an impact member in front, made of a continuous 'strip of spring steel with the end loops bent around rivets or pins and thence continued straight across in the rear of, and substantially parallel to, the impact or body bar to which the rear member is connected in the middle by means of a spacer block. The purpose of this parallel rear member is to reinforce the center of the impact or body bar as the reinforcing strip riveted to the impact bar does in the first-mentioned form. This bumper is connected with the side members of the automobile frame by supporting arms substantially as in the other form.

The alleged infringing device is also an invention relating to bumpers for motor vehicles, and its purpose is to absorb the shock of collision in coming in contact with another object. It is known as the Lyon bumper, for which patent No. 1,198,246 was issued to George Albert Lyon on September 12, 1916, on an original application filed April 21, 1913, and on a divided application filed June 30, 1916. Like the Hoover bumper, it is made of fiat strip steel; it has rearwardly bent open loops at each end of the impact bar. The inner ends of the loops are re-curved to form supporting arms by which the bumper may he attached to the frame of the automobile.

The particular features in which the Lyon bumper differs from the Hoover bumper are the bent open end loops of the impact bar in the Lyon bumper as contrasted with the elongated loops of the first form of the Hoover bumper and the closed end loops bent around rivets in the second form of the Hoover bumper. It is claimed by the defendant that the Lyon end loops are more resilient and serviceable than the Hoover end loops. The Lyon bumper also differs from the Hoover bumper in the structure of the impact spring. In the Lyon bumper the impact spring in [370]*370front or transverse member is made in two opposed resilient parts, with the ends overlapping each other in the middle; snch ends being clasped together with detachable clips. It is claimed by the defendant that this form of structure can be readily adjusted to car frames of different widths, and thát it is more resilient and serviceable as a spring than the Hoover single continuous spring.

The decree under consideration recites that Thomas A. Hoover was the first, original, and .sole inventor of the invention set forth and claimed in said letters patent; that during the summer of 1.910 said Thomas A. Hoover made and completed and caused to be publicly used in the United States the invention described and claimed in said letters patent No. 1,191,306; that said letters patent No. 1,191,306 are good' and valid; that the defendant, Chester N. Weaver, Inc., had infringed claims 1, 3, and 6 of said letters patent by the sale of .the Lyon bumpers complained of, and identified as"the Lyon resilient bumper and the Lyon convex bumper.

The decree recites further that none of the alleged defenses had been sustained; that plaintiff was entitled to recover of defendant, Chester N. .Weaver, Inc., the profits Received by it and the damages caused to the plaintiff by or resulting from such infringement by defendant by the sale of the Lyon resilient bumper and the Lyon convex bumper, and the plaintiff was' entitled to an accounting from said defendant Chester N. Weaver, .Inc., of such profits and damages caused by or resulting from such infringement by defendant, but that plaintiff had waived such accounting and its right to recover damages and profits over and above the nominal amount of $1 for and in respect of any and all infringing bumpers made, used, or sold by the defendant, Chester N. Weaver, Inc.

It was therefore adjudged and decreed that the plaintiff recover of the defendant, Chester N. Weaver, Inc., the sum of $1 as and in lieu of profits and damages by reason of said infringement, and that by reason of said infringement, and that by reason of the foregoing, no provision was made for an accounting, and the decree was accordingly made final. >

The suit upon which this decree was entered was commenced’ September 6, 1921. The defendant appeared and filed answer on December 3, 1921, and an amended answer on January 13, 1922. The answer denied the Hoover invention, and charged that every material and substantial part of the alleged invention had been known to and was in public use or had been invented by persons named in the answer, and had been described in printed publications referred to in the answer and amended answer.

The defendant also filed, on January 7, 1922, a list of interrogatories, calling upon the plaintiff to make certain disclosures concerning the Hoover invention. The interrogatories were answered by the plaintiff, and on September 8, 1922, the cause was referred to H. M. Wright, the special master in chancery, “to take the testimony and report the same to the court with his findings and conclusions thereon, subject to the full consideration of the court.” The special master proceeded to take the testimony as directed, making a voluminous record, and on November 27, 1922, announced to the parties his draft report.

During the proceedings there were introduced in evidence numerous depositions taken in various parts of the United States.

In his draft report, the master found, among other things, that Lyon conceived and reduced his invention to practice in the early part of 1911, and that Hoover conceived his invention in the spring of 1910, and reduced the same to practice in July, 1910. Both findings as to priority of conception were based upon oral testimony. The master reported that plaintiff was entitled to a decree, adjudging validity of its patent, infringement by defendant, and for an injunction as prayed-'for, and for a decree assessing damages, and for an accounting of profits from September 6, 1921, to the date of the master’s report. The defendant filed objections to the master’s report, and a petition for rehearing on July 25,1923. In a supplemental report, the master denied the petition for a rehearing, and on March 9, 1923, filed with the District Court his draft report, his supplemental report, and his report on the reference.

On March 29,. 1923, defendant filed in the lower court exceptions to said report" and supplemental report.
