In re Forstrom, 111 F.2d 181, 27 C.C.P.A. 1160, 45 U.S.P.Q. (BNA) 343, 1940 CCPA LEXIS 91 (ccpa 1940).

Opinion

LeNROot, Judge,

delivered tbe opinion of the court:

This is an appeal from a decision of the Board of Appeals of the United States Patent Office affirming a decision of the examiner rejecting, for lack of patentability over the cited prior art, claims 4 and 10 to 14, inclusive, of appellant’s application for a patent. Claims 12 and 13 were also rejected as being drawn to aggregations.

After appellant’s appeal from the decision of the examiner was taken, appellant proposed an amendment by adding a new claim, number 15, which, so far as the record discloses, was never entered. This claim is referred to by the board as a “proposed claim” and the board expressed the opinion that it, too, was drawn to an aggregation. However, in view of the action of the board, we will consider claim 15 upon its merits, its assumed rejection being included in the reasons of appeal, together with the other claims before us.

Upon the oral hearing before us appellant moved to dismiss the appeal as to claims 10 and 11, and this motion will be granted.

Claims 4 and 12 are illustrative of the subject matter involved and read as follows:

4. A supporting structure for an article comprising a caster bracket having a flange provided witli an opening for receiving a caster stem, a groove in said stem above said flange, and a split ring in said groove, said ring having a normal diameter greater than s'aid opening and being compressible by engaging the edges of said opening during insertion and removal of said stem.
12. A supporting structure for an article comprising a combined caster and shipping bracket secured to the article, said bracket' having three vertically spaced arms, the lower two arms each having an opening therein adapted to guide the stem of a caster and the upper arm being adapted to receive the thrust from the upper end of the caster stem, and means cooperating with the caster stem for yieldably holding the caster stem in place whereby the caster stem may be inserted and removed through the lower end of the bracket without disturbing the connection between the article and the bracket, a base, and fastening means extending through the opening in the lowermost arm for clamping said arm to the base and thereby securing the article thereto, said [1162]*1162lowermost arm being of suck construction as to withstand the clamping and shipping strains when secured to the base, the space between the lower two arms being open whereby said lowermost arm is accessible to the fastening means when the caster stem is removed.

Appellant’s claimed invention is concisely described in the examiner’s statement as follows:

The invention is directed to a combined caster and shipping bracket under the title of “Supporting Structures” and specifically involves a caster bracket having three vertically spaced arms, the bracket being permanently attached to an article of some weight such as a piece of furniture or washing machine. A caster, the stem of which has a split ring seated in a groove therein to be forced through holes in the two lower arms, is thereby removably attached to the bracket with the upper end of the stem bearing against the upper arm.
Upon removal of the caster and stem from the bracket the article may be readily fastened to the bottom of a shipping crate by merely inserting a bolt through the base and into the hole in the lowest arm. A nut can then be threaded onto the bolt above said lowest arm.
An important feature is the open construction of the bracket whereby plenty' of room is provided between the two lower arms to facilitate manipulation of the nut.

The references cited are:

Smith, 317,230, May 5, 1885.
Bell, 1,090,675, March 17, 1914.
Cilley, 1,155,043, September 28, 1915.
Herold, 1,468,208, September 18, 1923.
Everly, 1,559,078, October 27, 1925.
Janda, 1,869,966, August 2, 1932.

The reference Everly was applied only to claims 10 and 11, and as the appeal will be dismissed as to those claims this reference requires no consideration.

In each of the patents to Smith and Bell there is shown a caster bracket forming a supporting structure. On said bracket in each patent is a flange, provided with an opening to receive a caster stem which has a retaining means.

' The patent to Janda discloses a resilient split ring which holds the caster in the bracket by frictionally gripping the side walls of the caster stem receiving opening.

While the examiner stated that HeUolcl disclosed a split ring, such disclosure, if any, is to be implied from Figure 2 of the Herold drawings, and is not nearly so clear as the disclosure in the patent to Janda.

The reference Cilley discloses a device for temporarily fixing a chair on an auditorium floor by means of a plug inserted into the floor and a locking member', attached to the chair, inserted in said plug.

Appellant admits that his identical caster bracket, with three vertically spaced arms, is shown in the Smith patent.

[1163]*1163Claims 4 and 14 were rejected by the examiner on Smith or Bell in view of Herold, it being his view that no invention would be involved in using the split ring disclosed (in the examiner’s opinion) by Herold upon the structure disclosed by Smith. In his statement we find the following:

Claim 4 was rejected on Smith or Bell in view of Herold. In each of the patents to Smith and Bell there is shown a caster bracket forming a supporting structure. On said bracket in each patent is a flange indicated at r and 13 respectively, each flange being provided with an opening to receive a caster stem. The stem in each patent has a retaining means. There would be no invention in substituting for the stem retaining means of Smith or Bell the groove and split ring of Herold. While it is true that in Herold the split ring frictionally engages the side- wall of the cylindrical socket to retain the stem, it would if used in Smith or Bell function exactly as shown by applicant.

The Board of Appeals in affirming the rejection of these claims made no mention of the patent to Herold, but relied upon the patent to Janda for the disclosure of a split ring. In its decision it is stated:

We think we fully appreciate the practical advance which appellant has made. We believe, however, that it is clear that there would be no invention in substituting the split ring of Janda for the pin of Smith and it is our opinion that if the lower guide r of Smith were strong enough to hold the castor, it would have sufficient strength to hold the camera stand in a packing case if the castor were removed and a bolt placed through the opening. We believe, therefore, that none of the appealed claims, except claims 12 and 13, distinguishes over the castor holder of Smith in view of the prior art.

We are of tbe opinion that, so far as claims 4 and 14 are concerned, the structure disclosed by Smith would function in the same manner as that disclosed by appellant if the split ring of Janda were substituted for the retaining means shown by Smith.
