Opinion

Johnson, Judge,

delivered the opinion of the court:

This is an appeal from the decision of the Board of Appeals of the United States Patent Office affirming the action of the Primary Examiner in finally rejecting claims 5, 7, and 11, drawn to a beaming structure, for misjoinder with allowed claims 3 and 13, which were drawn to a method of lubricating a bearing, and claims 12 and 14 as aggregations of the subject matter of the allowed claims and the substance of claims 5, 7, and 11, in appellant’s application relating to a sealed antifriction bearing and a method of lubricating it.

Two references were cited by the Primary Examiner as illustrative of the classification of the subj ect matter claimed. They were not mentioned by the board, and as will hereafter appear, we need not consider them here.

Claims 3, 5, and 14 were considered illustrative by the board: They read:

3. The method of lubricating an antifriction bearing provided between its race rings with a closure member formed of a resilient imperforate mass of felted fibers, which consists in piercing a small hole through said closure member by a sharp-pointed hollow needle that yieldably presses the fibers aside and passes between the fibers to wipe off the needle and to make for itself a temporary, previously non-existing hole so small that the fibers will resiliently close said hole and again wipe off the needle as the needle is withdrawn from the closure member, and feeding lubricant through said needle into the bearing before the needle is withdrawn.
[1179]*11795. In a device of the character indicated, a pair of bearing members having a lubricant chamber therebetween, a sealing washer composed of an imperforate resilient material closing an end of the lubricant chamber, and a shield carried by one of the bearing members adjacent to said sealing washer and having a through aperture exposing a small area of the sealing washer and accessible at the outside of the bearing whereby a hollow needle may be inserted through said aperture to pierce a hole for itself through the resilient material and deliver lubricant into the lubricant chamber.
14. The method of providing for lubrication of a sealed antifriction bearing of the type wherein the space between the race rings is sealed up by a resilient imperforate sealing washer protected on the outside by a shield, which consists in providing'the shield with a small through aperture to expose a small portion of the resilient washer, inserting a sharp-pointed, lubricant conducting needle through the aperture, and thrusting the needle inwardly to pierce for itself a temporary, previously non-existing hole through the resilient washer for injection of lubricant into the bearing, the needle and the pierced hole being so small that the temporary hole will close up and disappear as the needle is withdrawn, the insertion of the sharp-pointed needle wiping off dirt and the withdrawal wiping off lubricant.

Permanently sealed antifriction bearings are widely used in industry. In the course of long usage or under conditions of high bearing temperature the sealed-in lubricant oxidizes and decomposes forming a tar-like deposit which is a cause of subsequent bearing failure.

Bearings of that type are constructed so that yieldable seals of some resilient material such as felt confine the lubricant to the area occupied by the rolling members between the race rings. To hold the deformable seals in position and to protect the bearing from dust, water and other foreign matter, the sides of the bearing are provided with permanently mounted metal seals.

Appellant solved the problem of preventing bearing failure in permanently sealed antifriction bearings due to the cause we have mentioned by providing small openings in the outer metal seal, and inserting therethrough a needle-shaped lubricant-feeding member of a pressure lubricator. The slim needle-like nose of the member pierces the inner seal of resilient material and permits the injection of grease to renew the lubricant therein. When the needle is withdrawn, the resilient imperforate inner seal closes the aperture produced by the needle and the bearing retains its permanently sealed quality. Affidavits of record establish that such a renewal of the bearing lubricant greatly increases the life of the bearing.

The examiner in the first office action on the application required division among three groups of claims: I, consisting of the claims directed to a method of lubrication; II, consisting of the claims drawn to the bearing and seal construction; and III, consisting of .claims drawn to a pressure lubricator.

[1180]*1180Appellant elected not to prosecute the claims of Group III. The Classification Examiner approved the requirement for division between claims of Group I (claims 1-3, 13) and Group II (claims 5, 7, 11) provided claims of the type of claim 12 were subsequently not allowed, stating that the latter claims include the subject matter of the method (Group I claims) and the article (Group II claims). The Classification Examiner supported his decision by saying:

The method of group I is applicable to any bearing having an imperforate resilient member as defined therein. Insofar as this method is concerned, the specific structure of the bearing and the shield is immaterial. The inventions are thus distinct and are separately classified á’nd searched.

Appellant objected to the requirement for division, hut elected to prosecute the claims of Group I, and claims 3 and 13 of that group ,were allowed. He also retained claims 5, 7, and 11 of Group II on the basis that should they not be allowed to go to issue in the same patent with Group I claims, the requirement for division would be appealed. Appellant added claim 14 to his application by an amendment at the time of his election of Group I, including claims 12 and 14 therein as drawn to a “method of lubricating.”

The examiner made the rejection of claims 5, 7, and 11 final on the basis of misjoinder, and the rejection of claims 12 and 14 final on the basis of aggregation. Claims 5, 7, and 11 were not considered by the examiner on their merits.

Since the Classification Examiner had conditioned his approval of the requirement for division as between Groups I and II on the non-allowance of claims 12 and 14, the appellant in his appeal to the. board first attacked the examiner’s rejection of those claims, and he makes that the first point before us on appeal.

The examiner based his rejection of claims. 12 and 14 for aggregation on the grounds (1) that they provided in addition to the method of lubricating the bearing, for “providing the shield with a small through aperture” (claim 14), and “making a small aperture through the metal Washer” (claim 12) which is a manufacturing step; and (2) that bearings provided with “such a shield” could be lubricated by other methods, as by spraying oil into the openings in the metal outer shield, or by immersing the bearings in a lubricant.

Appellant in his brief before the board took the position that claims 12 and 14 are each “directed to the method of providing- for lubricar tion” of the bearing, and hence are not aggregations. The examiner filed a reply to appellant’s brief with the board reiterating his position that the provision of an aperture in the claim with the lubricating process is aggregative. , ...*
