Opinion

ALMOND, Senior Judge.

This is an appeal from the decision of the Patent Office Board of Appeals affirming the examiner’s rejection of claims 1-5 of appellant’s application1 entitled “Salvo Ammunition For Multiple Bore Open Chamber Gun.” We reverse.

The Invention

The claims on appeal are directed to ammunition for a “multiple bore open chamber gun.” With reference to the figures set forth below, appellant’s specification contains the following description of the preferred embodiment of the claimed invention:

Reference is made first to FIGS. 6 through 8 illustrating a salvo-type, multiple projectile open chamber ammunition round 10, according to the invention. The illustrated ammunition is cased ammunition and comprises an outer yieldable, noncombustible cartridge ease 12 which is typically constructed of a suitable noncombustible plastic. * * * Cartridge case 12 has the preferred, generally triangular round shape in transverse cross-section which characterizes open chamber ammunition and includes front and rear transverse end walls 14 and 16, respectively, and longitudinal side walls 18. Contained within the cartridge case 12 are a plurality of projectiles 20 and a propellant charge 22.

The projectiles 20 are elongated longitudinally of the round, and, in this [1236]*1236instance, have conventional bullet shapes. In the particular salvo ammunition illustrated, the projectiles are three in number and are uniformly spaced about the longitudinal axis of the round in such a way that the projectiles are disposed in radial planes, respectively, containing the axis and the three longitudinal apex edges of the cartridge ease 12. Extending through the front end wall 14 of the cartridge case, in coaxial alignment with the projectiles, are bores 24. Sealed to the walls of these bores are obturating sleeves 26 frictionally receiving the projectiles. The propellant charge 22 fills the remaining interior volume of the cartridge case 12 in such manner that the propellant encapsulates the projectiles and their obturating sleeves. Mounted in the rear end wall 16 of the cartridge case 12 is a primer 28.

An open chamber gun, as described in appellant’s specification, has a rotating cylinder with cut-out triangular sections running its length. The cartridge is laterally inserted into one of these sections and rotated into firing position within the breech.

The “multiple bore open chamber gun” in which this ammunition is employed has a number of bores (barrels) equal to the number of projectiles in the round, in this case three. When a round is fired in the gun, the projectiles are discharged simultaneously as a salvo, thereby increasing the likelihood that the target will be struck.

Claims 1 and 4 are representative of those on appeal:

1. Salvo-type ammunition to be fired in a multiple bore open chamber gun of the character described, comprising :
an ammunition round of generally triangular round shape in transverse cross-section having a central longitudinal axis and containing a rear propellant charge and a plurality of forward positionally fixed mutually axially coextensive elongate projectiles having individual longitudinal axes substantially parallel to and uniformly spaced from said central axis of said round, and said projectiles being angularly spaced in a pre-determined array about said central axis.
4. Ammunition according to Claim 1, wherein:
said ammunition round is an open chamber ammunition round including an outer yieldable noncombustible cartridge case of generally triangular round shape in transverse cross-section and having a front end wall;
said wall contains bores coaxially aligned with said projectiles, respectively ; and
obturator sleeves sealed to the walls of said latter bores and receiving said projectiles, respectively.
The Rejection
The references relied upon were:
Dardick2 2,865,126 December 23, 1954
Hawthorne 3,437,039 April 8, 1969
(filed March 7, 1962)

Hawthorne describes a triangular shaped round for open chamber guns having three projectiles. Dardick describes a triangular round for open chamber guns having a single projectile which is surrounded by an obturating sleeve. 3

Claims 1-3 and 5 were rejected under 35 U.S.C. § 102 as anticipated by Hawthorne. Claim 4 was rejected under 35 U.S.C. § 103 as unpatentable over Hawthorne in view of Dardick. In the examiner’s view, it would have been ob[1237]*1237vious to one of ordinary skill in the art to use the obturating sleeve of Dardick in the round described by Hawthorne.

In the proceedings below, appellant did not challenge the examiner’s conclusion based upon his interpretation of the prior art. However, appellant did submit affidavits and corroborating evidence under the provisions of Rule 131 in order to have Hawthorne removed as a reference. The evidence submitted under Rule 131 consisted of two affidavits by appellant, a corroborating affidavit by an employee of the Dardick Corporation (Charles Scheidler), a document purporting to be a part of a proposal to be submitted to a licensee, hand-written report of firing tests allegedly carried out using cartridges like that described in the specification, and three photographs of a cartridge case like that described in the specification.

The examiner did not consider the affidavits and other evidence to be an adequate showing under Rule 131 for essentially two reasons. In his view, the evidence submitted neither adequately described the cartridge in question nor demonstrated that whatever cartridge was tested was actually reduced to practice before the filing date of Hawthorne. He summarized his position as follows:

In summary, all the exhibits submitted do not adequately describe the cartridge tested prior to the effective date of Hawthorne. The photographs submitted are clearly inadequate. The affidavits are not in sufficient detail so as to determine the cartridge developed and claimed reduced to practice prior to March 7,1962.
The tests submitted as exhibits of a reduction to practice are certainly inadequate for that purpose. The mere fact that bullets were ejected from a gun barrel is certainly a “far cry” from a reduction to practice in the ammunition art. In the explosive ammunition art safety through reliability, consistency and accuracy must be considered for a true reduction to practice.

For its part, the board noted, without comment, the examiner’s conclusions regarding the adequacy of the description of the cartridge in the affidavits and exhibits. However, after observing that the bullets tumbled in one of the firing tests reported, the board concluded that “ * * * to have a reduction to practice in this art the bullets should not tumble.”
