Opinion

Garrett, Presiding Judge,

delivered tbe opinion of tbe court: ■

Appellants bere seek review and reversal of tbe decision of the Board of Appeals of tbe United States Patent Office affirming that of tbe examiner rejecting, as lacking invention over prior art cited, tbe four claims numbered 3, 7, 8, and 9 of appellants’ application for patent entitled “For Method of Depositing Liquid Rubber in an Open Network.”

Tbe brief on behalf of appellants describes the article made by their method and gives a general description of the method itself as follows:

Appellants’ invention relates to an improved method of making an open elastic network of rubber by depositing the rubber directly upon a moving backing, which may be a temporary or permanent backing. The invention also includes the method of making rubber backed fabrics wherein the rubber network is deposited directly upon a textile fabric and adhered to such permanent backing. The network of rubber is also useful as a sandwich between two sheets of textile fabrics for the purpose of adhering the sheets together to form a porous fabric free from any exposed rubber surfaces. Such fabrics are elastic and porous and are particularly useful in the manufacture of bathing suits.
The network of rubber is produced by arranging a plurality of nozzles, transversely across the length of a movable backing, and discharging streams of liquid rubber from the nozzles upon the backing while its is moved in a lengthwise direction underneath the nozzles, and the nozzles are being reciprocated transversely of the movement of the backing. The novelty in the method is predicated upon the arrangement of the nozzles, or the streams of dispersions of rubber discharged therefrom, and the relative movement of the nozzles or streams in relation to the backing which is required to cause the streams of rubber deposited upon the .backing to be united in a network.

We here reproduce claims 3 and 9:

3. The method of making a pervious rubber backed fabric comprising the steps of directing streams of a dispersion of rubber upon the fabric from two spaced parallel rows of nozzles having the nozzles in each row arranged on lines perpendicular to the rows and equidistant from the nozzles of the other row, simultaneously advancing the fabric in respect to the nozzles in a direction substantially perpendicular to the rows of nozzles, reciprocating said nozzles in unison with an amplitude substantially equal to one-half the distance between the adjacent nozzles in each row in the direction of the rows at the rate of one stroke during the advancement of the fabric equal to the distance between the parallel rows, thereby laying down an undulatory' path of a dispersion of rubber on the fabric by each nozzle which is united with the adjacent path at the adjacent turning points in the adjacent paths to form an opening network, and drying the open network of rubber deposit to render it tough and elastic.
9. The method of making a pervious rubber backed fabric comprising the steps of forwardly advancing a web of textile fabric, comprising the steps of flowing streams of a dispersion of rubber upon the textile fabric from nozzles having orifices arranged on equidistant parallel lines extending in the (lirection of the advancement of said backing with said orifices on adjacent lines positioned out of transverse alignment an equal distance as measured from one to the other, holding, said orifices close to said fabric and forming banks of the dispersion of rubber on the sides of said nozzles from which said fabric advances, moving said [881]*881nozzles in unison back and' forth a distance at least equal to -the distance between said parallel lines during the advancement of the fabric a distance substantially equal to the distance said orifices are positioned out of transverse alignment spreading said banks deposited on said fabric into an interconnected network, and drying said network into an elastic network.

It will be noted that claim 3 provides specifically for the arrangement of the nozzles through which the streams of liquid rubber are dispersed in two parallel rows with the nozzle in each row arranged on lines perpendicular to the rows and equidistant from the nozzles of the other row.

Claims 7, 8, and 9 are not limited to the “two parallel row” arrangement, but provide an arrangement whereby the streams are dispersed, as expressed in claims 7 and 8, “on equidistant parallel lines extending in the direction of the advancement of said backing with the stréams on the adjacent lines positioned out of transverse alignment an equal distance as measured from one to the other.” As we understand it, the “adjacent lines positioned out of transverse alignment’' extend longitudinally the movement of the' fabric upon which'the liquid is being sprayed and “through the turning point of the lines of rubber.”

It will be observed that the latter portion of claim 9 specifies matter not recited in any one of the other claims. We refer to the clause reading:

* * * bolding said orifices [of the nozzles] close to said fabric and forming panics of the dispersion of rubber on the sides of said nozzles from which said fabric advances * * *, spreading said banks deposited on said fabric into an interconnected network * * *. [Italics ours.] - .

A comparison of the foregoing with clauses in claims 7 and 8 discloses that substantially the only change is the substitution of the word “banks” for the word “streams,” and there is no serious contention on the part of counsel for appellants that this feature distinguishes from the other claims in a patentable sense.

The following patents constitute the prior art cited as references:'

Campbell, 1,766,878, June 24, 1930.
Slack (British), 357,784, March 24,' 1931.
McLaurin, 1,919,798, July 25, 1933.

Specifically, the examiner rejected the claims “as lacking invention over Campbell in view of either McLaurin or Slack,” and the board did the same, describing the Campbell patent as the principal reference and the. others as auxiliaries. Of the two latter the board placed most emphasis on the Slack patent. . .

The Campbell patent, which embraces both product and. process claims, relates primarily to the coating of materials used for floor coverings, such as linoleum for example, in a manner by which the coating substances (which are plastic substances) produce “striped, [882]*882striated or wavy effects so as to simulate marble, granite or wood graining” and which “can be also employed for producing- other characters of designs such as geometrical repeats.” A further teaching relates to the use of colors, the plastic substances of different colors being so dispersed that they “shade off into each other and at times * * * intermingle and produce new tints * *

As an apparatus for use in carrying out the process, Campbell discloses a series of pans (six are shown in Fig. 1 of the drawing) for holding the coating material. The pans have a plurality of outlets, or orifices, in their side walls through which the coating substance passes to the fabric. The specification states that the outlets are “preferably equi-distantly spaced.” The floor covering which is being treated passes beneath the pans, and the deposits of the coating substances generally are made longitudinally the material being coated.
