Opinion

Graham, Presiding Judge,

delivered the opinion of the court:

The appellant made application to the United States Patent Office for a patent upon certain “new and useful improvements in Automatic Contour Shaping Fixture.” The apparatus for which patent was sought was a device by which objects could be ground into a shape identical with a form which it was desired to duplicate, particularly small objects of glass, like watch crystals, or lenses of optical devices, curved or straight in cross section. A fairly good idea of the device may be had by examination of two claims which are thought to be typical, namely, 43 and 47, which are as follows:

43. In a contour shaping machine, the combination with a pattern, and work holder operable therewith, of a shaper and a gauge in axial alinement, a carriage for supporting, and moving in a fixed path said pattern and said work [1061]*1061holder toward and from said shaper and said gauge, means for rotating said work holder and said pattern, said gauge having a working surface of varying concentric diameters against which the said pattern may ride, said working surface being concentric with the shaping surface of said shaper, means to mierometrically longitudinally adjust said gauge and said pattern relative to each other whereby the peripheral contour of said pattern is accurately reproduced in direct proportion on a piece of work, which may be held by the work holder and shaped by the shaper, at all points of said relative adjustment, and means for loekingly maintaining said adjustment.
47. In a contour shaping apparatus, the combination with a pattern and a work holder operable therewith, of a gauge against which the pattern may ride, and a shaper, the working surface of said gauge and of said shaper being concentric and said gauge and said shaper being in axial alinement, whereby the concentricity between said working surfaces are constantly maintained, a carriage for supporting, and moving in a fixed path said pattern and said work holder towards and from said shaper and said gauge, means for rotating said work holder and said pattern, means to longitudinally vary the working surface of the gauge relative to the working surface of the shaper, and means for locking the gauge in any position.

The Board of Appeals, in its decision, described the device as follows:

The invention^relates to a contour-shaping machine. As shown in Fig. 1, it includes a stationary standard 77 on which a frusto conical gauge 83 is mounted for axial adjustment. A rotatable grinding wheel or shaper 85 concentric with the gauge is mounted adjacent to it. A work-holding frame is pivoted on a standard at one side of the gauge and shaper so that it can be swung toward and away from them. This frame carries a work-holder 73 and 74 and a pattern 87 on the same shaft as the work-holder. When the work-holder frame is swung toward the shaper 85, the pattern 87 engages gauge 83. As shown in Fig. 3, the pattern and work-holder are relatively axially adjustable. Likewise, the gauge 83 is axially adjustable with respect to the shaper. The adjusting means include micrometric screws.

Some claims were allowed, but claims 43 to 47,. inclusive, were denied by both, the examiner and Board of Appeals. A petition for rehearing was filed and denied, and the case comes here for review. The examiner cited the following references in his rejection:

Gubbins (British) No. 3265, July 10, 1882.
Besson et al., 374,332, Dec. 27, 1887.
Bader, 737,313, August 25, 1903.
Long, 686,676, Nov. 12, 1901.

The Board of Appeals cited the same references but the record does not contain the Bader and Besson et al. patents, so that the court has not had the benefit, of an inspection of the same. However, their application to the case is not left in doubt by the record. The examiner was of the opinion that claims 43 to 47, inclusive, were not patentable over the patent to Gubbins, “especially in view of patent to Long or Bader or Besson et al. as applied above to claims 28 and 38 to 40 inclusive.” As to this part of the case, the examiner states:

[1062]*1062It seems that the definition of the work holder in these claims (in claim 43, line 2 and claim 44, line 2 for instance) can be read only on applicant’s rotatable work clamping heads 49 and 57 and spindles 48 and 56 because these claims also call for means for rotating the work holder. The rocking frame 24, 27 etc. for supporting the work holding and rotating spindles 48 and 56 and heads 49 and 57 is not a part rotated by the work holder rotating means and probably cannot be considered to be included in the definition of the work holder. The rocking frame is not otherwise included in these claims and the statement in claim 43, lines 3-5 for instance, and the other claims to the effect that the pattern and work holder are movable in a fixed path relative to the shaper and gauge claims the function of the rocking frame without claiming the rocking frame as a tangible structural element. Therefore, these claims do not appear to require the Gubbins patent to show a support for work holder S of that patent.

As to the swingable unit upon which the work holder is mounted,, the Board of Appeals says:

Some of the appealed claims recite that the work-holder and the pattern are mounted on a swingable unit. The Gubbins patent shows the work-holder and pattern connected together as a unit, and this unit is moved toward and away from the shaper. Since it is old in other patents cited to mount the work-holder and the pattern on a swingable frame, we believe that no invention is involved in making this change in' Gubbins.

These, therefore, constitute the positions of the Patent Office tribunals upon the question of the swingable arm for the work unit.

Throughout the prosecution of this application, the appellant has insisted that he has developed a new and valuable feature,, namely, the micrometric adjusting means which his device contains. But little attention has been given to this matter by the Patent Office tribunals. The Board of Appeals, on its part, says the-following:

Applicant’s main argument is that Gubbins does not show micromeric-adjusting means for the gauge 0 and locking means for it in any adjusted position. If the screw threads in the patent are made with sufficiently small pitch, it is evident that the gauge 0 can readily be adjusted to any degree of' accuracy necessary. Hence, the patent has micrometric adjusting means. Apparently, the friction between the screw threads is depended upon in Gub-bins to hold the gauge in its adjusted position so it will not shift. If the threads fit tight, this will be sufficient to retain the gauge in adjusted position,. If an additional set screw be desired, it can be added to the gauge hub and thus hold the gauge- more securely. We do not regard this as involving invention.

It will be observed that claim 43, which is hereinbefore quoted, recites, in part: “* * * means to micrometrically longitudinally adjust said gauge and said pattern relative to each other * * * and means for lockingly maintaining said adjustment.” This language is contained in all the rejected claims, except claim 41.

We are told by the Solicitor for the Patent Office that the patents which are absent from this record, namely, Bader and Besson et al.,.
