63 F.2d 987 | C.C.P.A. | 1933
delivered the opinion of the court:
This is an appeal from a decision of the Board of Appeals of "the United States Patent Office, affirming that of the examiner, rejecting, for want of invention over the prior1 art, claims 18, 19, 21, and 22 of appellant’s application for patent; claims 3 to 11, inclusive, 17, 20, 23, and 24 were allowed by the examiner. Claim 18 is illustrative of the claims on appeal and reads as follows:
18. In blowpipe apparatus, the combination of blowpipe supporting means, mechanism for effecting relative movement of said supporting means and the*986 work operated upon, and blowpipe means mounted on said supporting means adapted and arranged to deliver intersecting gaseous beat or cutting jets against tbe same side of tbe work and in a plane transverse to tbe direction of sucb movement.
The reference relied upon by the board is:
Bucknam, 1084692, January 20, 1914.
The invention covered by the claims on appeal is thus described in the decision of the board:
Tbe invention claimed is a machine for cutting metal work. It comprises a supporting means wbicb may be moved relatively to the work. 'On this sup: porting means a pair of cutting torches are adjustably mounted and arranged so as. to emit converging cutting jets to tbe metal work. Tbe jets will then cut tbe metal to form beveled edges on it.
Discussing the reference Bucknam, the board said:
The Bucknam patent discloses a gas welding and cutting apparatus. It comprises a support on wbicb are movably mounted tbe arms 13 and 14. In tbe form shown in Figure 1, a cutting torch is mounted, on each arm and tbe torches are arranged to converge toward each other. They are intended to be mounted on opposite sides of tbe metal to be cut. In Figure 9 tbe torches are arranged on tbe same side of the metal to be cut, and with one torch behind the other. In Figures 10 and 11 the torches are arranged for adjustment transversely of tbe arms 13 and 14.
The board further called attention to Figure 12 of the Bucknam drawings, showing a method of mounting torches, wherein each torch is connected to a bar by means of a collar carrying a horizontal pin, inserted in an opening in said bar and retained by a set screw, following which the board said:
* * * With this construction it is obvious that tbe torches can be adjusted so as to converge toward the work. If they be so adjusted, it is obvious that a single cut can be made having beveled edges. We believe that since tbe structure shown in this patent has all the capability of the structure covered by the claims, the reference is sufficient to anticipate the claims. Any mechanic of course can adjust the torches by means of the set screws. If adjusted to converge toward the work they will perform the same function as in the present invention.
Bucknam’s specification, referring to this point, states:
* * * Angular adjustment of the torches to direct the jets either perpendicular to the surface of the work or at any inclination is provided for by pivoting the holders 49 to the carriages 46, as indicated at 50. * * *
The Board of Appeals in its decision did not refer.to the above-quoted recital in the Bucknam specification, but relied upon his drawings as disclosing the structure corresponding to the claims here in issue. We do not find it necessary to decide whether said recital is material to the issue here-involved,, for we are clear that the board did not err in holding that the drawings are sufficient to afford a proper basis for the rejection of appellant’s claims. While
It is our view that the reference, Bucknam would suggest to one. skilled in the art the adjustment referred to in the above quotation, from the decision of the board, and therefore appellant’s claims do not involve invention in view of the said reference.
While appellant contends that the horizontal pin in the Bucknam drawing may be other than round, thus preventing, its rotation, the shading in the drawing clearly indicates that the .pin is circular in cross section.
The decision of the Board of Appeals is affirmed.
