Opinion

Johnson, Chief Judge,

delivered the opinion of the court:

This is an appeal from a decision- of the Patent Office Board of Appeals, rejecting claims 8 to 13, inclusive, of appellant’s application No. 143,760, filed February 11, 1950,: for “Improvements in Concrete Inserts,” as unpatentable over the prior art. No claims have been allowed.

Claims 8 and 9 are representative of the appealed claims and read ■as follows: ’

8. A concrete insert comprising a metallic channel member having pairs of longitudinally spaced anchor tongues projecting outwardly from the back wall thereof, said tongues consisting of portions of the wall material displaced angularly from the wall whereby openings result in the latter; and cover plates fitted over said openings and having portions extending thereinto to prevent displacement of the plates.
9. A concrete insert comprising a channel member and an end closure member, said closure member consisting of a strip of metal provided adjacent one of its ends with angularly disposed wings fitting into the end of said channel member, said strip having an angular flange at its other end extending in a direction opposite to said wings to provide an anchor for the channel.

The invention relates to concrete inserts of the type used to facilitate attachment of objects to concrete ceilings, walls or the like. In essence, it consists of a U-shaped channel member with pairs of tongues punched out of the back wall of the channel, said tongues serving as anchors to secure the channel member in the concrete. Each tongue of a pair is so punched out of the back face of the channel member that it lies in a plane perpendicular to the plane of the back face. The openings in the back face, formed by the punching out of the tongues, are closed by means of cover plates having extensions which fit into said openings to prevent displacement of the plates. The cover plates are disclosed as being forcibly fitted between each pair of tongues and as serving to prevent loose concrete from entering the channel member. End closures are provided for the channel member, said closures fitting into the ends of said channel member by means of wing extensions. These closures also serve to prevent loose concrete from migrating into the channel member. In one embodiment, a flange extension with notches therein is provided at the portion of the end closure which is flush with the front face of the channel member (viz — the open end of the channel), said extension and its notches serving to receive nails for securing the closure to the concrete forms. In another embodiment, the end closure is extended in the direction of the back face of the channel member to provide additional anchoring means to secure the channel in the concrete. The [826]*826alleged advantage of the disclosed insert is that it provides for ad-justability of the position of the element secured in the insert and “that the channel, without modification, may be rolled and cut off to any desired length and subsequently provided with anchor tongues, cover plates, etc.”

The references relied upon are:

Brown, 827,613, July 31,1906.
Chase, 1,409,524, March 14,1922.
Tomkinson et al., 1,491,571, April 22,1924.
Timm, 1,561,126, November 10,1925.
Attwood, 2,345,650, April 4, 1944.
German Patent, 480,624,1929.

The Brown patent, insofar as pertinent, discloses a concrete insert consisting of an elongated, square tube with struck-up portions from its rear surface serving as anchors. The tube is slotted at the opposite face so that objects to be received may be inserted therein.

The Chase patent discloses a concrete insert consisting of a trough whose sides flare outwardly on the concrete side of the insert and which is provided with a cover plate containing projections at each end thereof to aid in securing the cover on the trough.

The Tomkinson patent, insofar as pertinent, discloses a concrete insert in the form of a box having closed ends. Flush with the front of the box, on each end, is a flange having a notch therein for receiving a fastener to anchor the insert to the form prior to pouring the concrete.

The Timm patent discloses a concrete insert consisting of a U-shaped channel member with a fin extending perpendicularly from the back side thereof. Struck out of the fin are tongues used to anchor the channel member in the concrete. End closures (caps) fit over the ends of the channel member to prevent concrete from entering the ends of said member.

The Attwood patent discloses a supporting structure (viz — for scaffolding, ladders, etc.) comprising a channel member identical to appellant’s with end closure means for said member.

The German patent discloses a concrete insert consisting of a slotted face plate with tongues struck-up from said plate in such a manner that they are secured to said plate at the ends thereof and are perpendicular thereto. A U-shaped cap is inverted and press-fitted between the turned-up sides of the face plate. Cleats are provided on the tongues to urge against the inverted cap and secure it in place.

Claim 8 was rejected by the board as unpatentable over Brown in view of Chase. The board was of the opinion that, though Brown makes no provision for preventing entrance of soft concrete into the channel through the openings left when the tongues are struck there[827]*827from, this feature was suggested by Chase. We agree with the board that claim 8 does not define invention over these two references. In our opinion, the “tube” of Brown, with its “struck-up” portions, is the full equivalent of appellant’s channel and tongue element. As urged in the Solicitor’s brief, the distinction is semantic only. If it were discovered that the loose concrete tended to migrate into the channel through the openings formed by striking up the tongue elements, it would be obvious to cover the openings, as suggested by Chase. The projections on the cover plate of Chase are equivalent to those claimed by appellant. Appellant urges that the cover plate of Chase is not equivalent to his since it is part of the box portion which has no anchor tongues as in appellant’s element; that Chase relies on the shape of his box to prevent it from being pulled out of the concrete.

This appears to be a repetition of the age-old argument that for a reference to be applied against a claim in combination with another, the teachings of the former must be incorporated bodily into, those of the latter. This argument has been rejected before. In re Henley, 44 C. C. P. A. (Patents) 701, 239 F. 2d 399, 112 USPQ 56. The Chase reference was relied upon by the board not for its overall teaching as to concrete inserts but for its teaching broadly the use of a plate to cover an aperture through which the passage of soft concrete is to be prevented. For this purpose it is sufficient.

Appellant further urges that Brown must fail as a reference since the embodiment applied against appellant’s claims was the tubular structure disclosed by Brown; that “if, as Brown states, he uses a tube, neither he nor the Examiner discloses how the ‘stirrup’ may be ‘struck up’ ”.
