Mojonnier Bros. v. Tolan Machinery Co.

MODARELLI, District Judge. This action was instituted by Mojonnier Bros. Co., Inc., against Tolan Machinery Co., Inc., to enjoin alleged infringements of Patent No. 2,1'69,054 issued to Julius J. Mojonnier, plaintiff’s assignor, on August 8, 1939, and Patent No. 2,179,949 issued to Harry G. Mojonnier, plaintiff’s assignor, on November 14, 1939. Both patents presently are owned by plaintiff, who also demands an accounting of profits, damages, counsel fees, and costs. At the trial, defendant withdrew its counterclaim based on the alleged unfair competition of plaintiff. Defendant’s answer to the complaint put in issue whether plaintiff’s patents are invalid because they were anticipated by the prior art. This action involves the validity of claims 5 through 12 of Patent No. 2,169,-0541 and all of the five claims of Patent [733] No. 2,179,949.2 Although the answer put in issue all of the claims of the former patent, the parties stipulated that there be no adjudication of claims 1 through 4. Newburgh Moire Co. v. Superior Moire Co., 3 Cir., 218 F.2d 580, 583. Patent No- 2,169,054 The nature of the patent is described by the patentee in the patent specification. The patent relates to liquid treating apparatus, the object of which is to change the temperature in the treated liquid by passing heat through a metal wall or partition. The heat is either supplied or absorbed by a temperature modifying fluid, depending on the direction of flow of the energy. Where the heat passes from the modifying fluid to the treated liquid the latter is heated; but where the heat passes from the treated [734] liquid to the modifying liquid the former is cooled. Corrugated metal sheets are used for the principal surface members of the unit and they are spaced apart, the liquid passing downward over these sheet surfaces while it receives or gives off heat. Suitable inlet and outlet connections are provided for the flow of the temperature modifying medium as well as suitable delivering and collecting means for the liquid being treated. Another purpose of the patent is to permit an efficient cleaning of the several heat transferring units. Each unit is mounted on an axis extending along one of its edges so that it can be swung into and out of normal operating position. By locating the axes of the units close together, the units can be compactly grouped for service and separated readily for cleaning. Preferably, the units are mounted so that they may be opened out like the leaves of a book. Another feature is in the arrangement of the units one above another or one group above another group. With such an installation, the liquid under treatment passes from one kind of treatment received from the upper units to another kind of treatment administered by the lower units. Thus in treating milk, water may be the controlling medium of the upper units and ammonia or brine the controlling medium of the lower units. Plaintiff contends that its device has four advantages over the prior art: (1) Closely parallel leaves which yield large cooling capacity in a small floor area; (2) the rotatable leaves allow easy cleaning; (3) the connections for the coolants need not be disconnected when the leaves are rotated to a cleaning position; and (4) it is safe to use water, brine, or ammonia as a coolant. Essentially, plaintiff maintains that its device is an improvement in trickle type coolers in that it has a plurality of hinged leaves which are parallel and close together and swingable to wide angular positions for cleaning without disrupting the coolant connections. ' Since the court concludes that claims 5 through 12 of the patent are invalid because of prior art anticipation and lack of invention, there is no need to discuss or decide the issue of. infringement. This is a combination patent in that plaintiff’s apparatus is entirely composed of old components. Great Atlantic & Pacific Tea Co. v. Supermarket Equipment Corp., 340 U.S. 147, 152, 153, 71 S.Ct. 127, 95 L.Ed. 162. Accord, Packwood v. Briggs & Stratton Corp., 3 Cir., 195 F.2d 971, 973, certiorari denied 344 U.S. 844, 73 S.Ct. 61, 97 L.Ed. 657, rehearing denied 344 U.S. 882, 73 S.Ct. 174, 97 L.Ed. 683. Those cases set forth the criteria by which this court must judge validity: Do the old elements perform any additional or different functions in the combination than they perform out of it? Has plaintiff merely united old elements without changing their respective functions ? At the time Julius J. Mojonnier applied for his patent, the idea of using a plurality of closely parallel hinged leaves was known to the art. The Reid Patent No. 557,883 for a milk cooler provides for cooling surfaces over which flows the substance to be cooled. The cooling surfaces consist of two corrugated metal plates connected at opposite ends a slight distance apart by filling-strips. The Brophy Patent No. 628,689 for a heat radiator describes hinged leaves or coils; the leaves are hinged upon a post which forms part of the return-pipe through which the, water or steam flows after having passed through the heating coils. That patent also provides brackets to allow the use of two or more leaves or coils. The Brandt Patent No. 707,081 for an atmospheric steam condensing apparatus describes “a series of corrugated walls which are mounted in two vertical end pieces or split headers, each two of such walls providing a continuous surface and constituting a unit, any number of which may be associated by adding or assembling one or more units — that- is to say, the area of space occupied by a condenser may be increased or decreased, according to the number of units or con [735] denser-sections that are brought together.” As to the second advantage claimed by plaintiff, rotatable leaves are described in the aforementioned Reid Patent: “ * * * and the invention consists in an improved manner of sustaining the cooling-body to admit of its being turned from its operative position to allow access to its rear side; * * *. “In order that access may be had to the rear side of the cooler, which when in operation is sustained in an upright position by means of brackets M M, &c., I so attach the cooler to the brackets that it may be swung bodily outward from the wall on a vertical axis.” The aforementioned Brophy Patent describes an invention relating to “heat-radiators of the kind wherein hinged leaves or coils are employed for facilitating cleaning, the objects of the present invention being to simplify the construction of such apparatus and increase the facility with which access to the various parts can be obtained. “According to my present invention instead of hinging the leaves upon a post or upright which formed no part of the heating system I now hinge them upon a post which forms a part of the return-pipe through which the water or steam flows after having passed through the heating coil or coils.” That patent also describes a hinged leaf with a series of heating pipes fixed at their ends to the castings. “This arrangement for hinging the leaf 0 permits of the latter being turned in any direction in order to afford access to all the parts for cleaning the same.” As to the third advantage claimed by plaintiff, the Sheeder Patent No. 210,714 for an improvement in paper-board driers provides for connections between steam pipes and manifolds constructed of flexible pipe or gum tubing to permit the elevation and lowering of the pipes without interfering with the circulation of steam through them. The Trageser Patent No. 46,509 for an improvement in coils for steam heating shows that when a connecting coil is turned up for cleaning out a vessel, other pipes will also be turned. Moreover, Brophy hinged the leaves upon a post which forms a part of the return pipe through which the water or steam flows after having passed through the heating coil or coils. As to the fourth advantage claimed by plaintiff, the court concludes that in each of the aforementioned patents it would have been possible safely to use one of plaintiff’s coolants. Moreover, the Morison Patent No. 529,288 for heating liquids by steam describes a method for the free passage of water in the apparatus. Plaintiff has not shown any inventive faculty. Cf. Hunter Douglas Corp. v. Lando Products, 9 Cir., 215 F.2d 372, 375; Fowler v. Honorbilt Products, Inc., 3 Cir., 131 F.2d 153, 155; Lyons v. Construction Specialties, Inc., D.C., 112 F.Supp. 317, 322. Patent No. 2,179,949 The nature of the patent is described by the patentee in the patent specification. The patent relates to liquid treating plants whereby the liquid to be treated is subjected to the action of a heat exchange medium and also to the action of an atmosphere or stream of conditioned air or the like. The patent utilizes a surface type heat exchanger and provides for the projection of a stream of conditioned air against and among the heat exchange elements. One object of the patent is to use a cooler Which can be readily and thoroughly cleaned; also to produce a wort cooler plant which will occupy minimum floor space. By reason of a close fit of the covers and casing which constitute the housing, it is possible to control the condition of the air, gas, or other fluid which is projected into the inelosure containing the cooling elements. Preferably, air is cleaned and heated to a suitable temperature and then forced into the interior of the housing. By projecting a stream of air through the interior of the cooler, spent air and vapors are carried away. [736] Is there patent validity in the use of a wide and shallow nozzle to blow a stream of conditioned air among heat exchange elements (which differentiates the two patents from each other) ? Since the court concludes that the patent is invalid because of prior art anticipation and lack of invention, there is no need to discuss or decide the issue of infringement. Hunziker’s Patent No. 1,543,853 for an apparatus for deodorizing cream discloses a blower capable of supplying large volumes of air under pressure; the air supplied by the blower is preferably heated so that it can be used in maintaining the contents of the tank at the desired temperature. Hunziker’s Claims 2 and 3 include a “means for forcing air through said container in a plurality of vertically directed jets closely spaced throughout the horizontal area of said container * * and Claims 5, 6, 7, and 8 include a “means for forcing air upwardly through said container in a plurality of vertically directed jets closely spaced throughout the horizontal area of said container * * The Vincent Patent No. 2,031,437 for a gas washer describes the use of a nozzle to discharge cleaning sprays; Claim 1 includes “a plurality of nozzles arranged to discharge generally crosswise * * Such a description does not materially differ from the plaintiff’s claims. And surely one skilled in the art could have used the Vincent Patent description to meet the function of the wide nozzle described by plaintiff’s patent. Judgment will be entered for the defendant on plaintiff’s complaint determining that claims 5 through 12 of Patent No. 2,169,054 and Patent No. 2,179,-949 are invalid for want of invention. The defendant is entitled to court costs, but not costs of suit. The foregoing opinion shall constitute findings of fact and conclusions of law, as required by Rulé 52, 28 U.S.C. An order may be submitted in conformity with the opinion herein expressed. Footnotes [1] “5.
