Carlton Manufacturing Co. v. Fram Corp., 201 F. Supp. 18, 132 U.S.P.Q. (BNA) 197, 1961 U.S. Dist. LEXIS 5984 (D.R.I. 1961).

Opinion

DAY, District Judge.

In this action plaintiff seeks a declaratory judgment that U.S. Letters Patent No. 2,824,707 issued to the defendant on February 25, 1958, as assignee of Walter V. Kennedy, and relating to the construction of a sheet metal spool is invalid, or if valid, is not infringed by the plaintiff.

In its complaint the plaintiff asserts that said patent is invalid because of pri- or art anticipation and want of invention, etc., and further, that in any event that the proper scope of said patent does not cover sheet, metal spools manufactured and sold by the plaintiff.

In its answer the defendant admits that it is the owner of said patent, admits that the plaintiff manufactures and sells certain sheet metal spools as claimed by it, asserts that said patent was legally issued to it and denies that the plaintiff may rightfully manufacture and sell its spools without infringing said patent. It further asserts it has given written notice to the plaintiff of its infringement and counterclaims for injunctive relief against further infringement, for an accounting of profits and damages, costs, etc.

The Kennedy patent contains three claims which read as follows:

“1. A spool comprising a metal barrel having projecting tabs at the ends thereof and a metal head at each end of the barrel, each head being provided with slots to receive the tabs and with an annular channel having a wall disposed at right angles to the plane of the head and forming a ring that embraces an end portion of the barrel, and wherein said tabs project through said slots and are bent laterally away from the drum axis and downward into the channel to lie parallel to the body of the barrel to embrace said wall with the ends of the tabs abutting against the bottom of the channel.
“2. A spool according to claim 1 wherein the tabs are bent laterally at an angle of 90° and downwardly through another angle of 90°.
“3. A spool comprising a metal barrel having projecting tabs at the ends thereof and a metal head at each end of the barrel, each head being provided with a sunken annular channel having a wall disposed at right angles to the plane of the head and forming a ring that embraces an end portion of the barrel, each head also having at least three arcuate slots disposed within said wall, and wherein said tabs project through said slots and are bent laterally away from the axis of the drum at an angle of 90° and downwardly at a second angle of 90° into the channel to lie parallel to the body of the barrel to embrace said wall with the ends of the tabs abutting against the bottom of the channel.”

The file wrapper history of the Kennedy patent shows that the application [20]*20therefor was filed on December 2, 1955. As originally filed it contained three claims. These claims were rejected by the examiner on August 29, 1956 on the ground that they were anticipated by the Mungen patent No. 2,036,969, issued April 7, 1936. No other reference was cited by the examiner in his rejection. On December 28, 1956 the applicant amended his application by inserting in claim 1, line 8, and in claim 3, line 10, after the word “channel” the words “to lie parallel to the body of the barrel”. Applicant made no amendment to claim 2 as originally filed. In requesting allowance of his application, as amended, he emphasized that his construction greatly increased the strength of the head securing means over that disclosed by Mungen. In support of this he stressed that (1) his construction provided a circular ring or wall which surrounds and embraces the barrel superior to the embracing channel shown in Mungen and (2) that the tabs described in his claims are wide and arcuate and are bent through an angle of 180° so that they lie parallel to the body of the barrel thereby causing the ends of the tabs to seat firmly against the bottom of the annular channel in the head. In such a construction, he contended, any outward pressure on the heads would be exerted against the ends of the tabs. These features, he claimed, differentiated his construction from that of Mungen and provided a much more secure construction than did the latter. Subsequently, on December 12, 1957, the examiner allowed said application, as amended. In the Letters Patent as issued the only reference cited by the examiner was that previously cited in his rejection of the original application, namely, Mungen.

The Kennedy patent purports to provide a new and novel means for firmly securing the spool heads to the spool barrel in a sheet metal spool. As shown by the drawings and specifications, Kennedy has provided a sheet metal cylindrical barrel having three projecting tabs at each end thereof. These tabs are designed to be inserted into and to project through corresponding slots in the heads. The method of attaching each of the heads is identical.

Each of the heads is countersunk or indented near the hub portion thereof to form a circular or annular channel having a wall disposed at right angles to the plane of the head, forming a ring which is adapted to embrace an end portion of the barrel. In assembling, an end portion of the barrel is forced into said ring which embraces it, the tabs thereof projecting through said slots in the head. Said tabs are then by means of a specially constructed die bent successively in two directions — first laterally and outwardly from the axis of said barrel at an angle of 90°, and then downwardly at a similar angle into said channel so as to lie parallel to said wall and to embrace the same with the ends of said tabs abutting against the bottom of said channel.

During the trial the parties presented much testimony as to the prior art in the construction of sheet metal spools and sheet metal containers. Many patents were also introduced as exhibits.

After a consideration of all of the evidence and a study of the pertinent prior art, I am convinced that the general structure and means for securing the heads to the barrel, asserted in the Kennedy claims, were anticipated by Mungen patent No. 2,036,969, Mossberg No. 773,-218, issued October 25,1904, the Seymour spool, the early Mason spool and the Orianna spool, as shown in Cohen No. 2,-857,665, which was being sold commercially prior to the date of Kennedy’s alleged invention and with which he was admittedly then familiar.

Mungen shows a spool barrel with projecting tabs, a spool head with slots to receive the tabs, and an annular channel disposed at right angles to the plane of the head forming a ring that embraces an end of the barrel wherein the tabs project through the slots in the head and are bent laterally away from the barrel axis and downward into the channel to embrace said wall, with ends abutting against the bottom of said channel. However, it is true that Mungen did not teach that the tabs should be bent at an [21]*21angle of 180°, as did Kennedy, and it is equally true that Mungen employed narrow tabs in contrast to Kennedy’s construction.

Mossberg clearly taught a head construction similar to Kennedy’s with the same wall or ring on the head to strengthen it and to embrace the barrel, producing a stronger union between the head and the barrel.

The testimony establishes that the Seymour spool, which was being sold commercially in 1934, used tabs on the barrel which were pushed through slots in the head and bent outwardly at an angle of 90°.
