Opinion

Garrett, Presiding Judge,

delivered the opinion of the court:

There is here brought before us for review the .decision of the Board of Appeals of the United States Patent Office affirming the decision of the examiner rejecting two claims embraced in -appellant’s application for patent entitled “For Fruit Bobbing Apparatus.” Twenty-seven claims embraced in the application were allowed by the examiner. Those claims were not involved in the appeal to the board, nor are they involved here. The two rejected claims numbered, respectively, 12 and 29, which were involved in the appeal to the board and in the appeal to this court, read:

12. A device for severing or bobbing the necks and stems of pears comprising fruit holding means adapted to hold a pear with the neck of the pear .extending beyond the holdiug means and its stem axis extending in a predetermined direction, means adapted contactingly to encircle the neck of the pear to hold the neck of the pear firmly, cutting means movable transversely of the stem axis to bob the pear while so held, and means to discharge the bobbed end from the encircling holding means.
29. End bobbing means for pears comprising fruit holding means adapted to support a pear with the neck end of the pear extending beyond the holding means, a hollow member open at one end to receive and encircle the neck of the pear to hold the pear firmly therein, and cutting means shiftable transversely of the axis of the pear between the hollow member and said holding means to sever the stem end of the pear from the body thereof.

Two patents were cited as references:

Berrini, 490,133, January 17, 1893;
Thompson, et al., 2,139,704, December 13, 1938.

The Berrini device is one for cutting off the ends of eggs in the shell.' The patent to Thompson et al. is for a fruit preparation machine.

Appellant’s complete machine is somewhat complicated. The application contains five sheets of drawings,. the various features being delineated in 13 figures. The structure outlined in the appealed claims constitutes a subcombination of the complete device and relates particularly to mechanism for severing the stem ends of pears from the whole fruit.

The features, or limitations, of appealed claim 12 especially emphasized before us as rendering the subcombination patentable are— (1) means adapted contactingly to encircle the neck of the pear,” (2) “cutting means movable transversely of the stem axis,” and (3) “means to discharge the bobbed end from the encircling holding means.” In claim 29 the “means adapted contactingly to encircle the neck of the pear” (named in claim 12) is described as “a hollow member open at one end” and.the means for severing the pear end is ■defined as “cutting means shiftable transversely of the axis.of the pear.” Claim 29 has no limitation respecting means for discharging •the bobbed end after its severance.

[919]*919The structure embracing the foregoing limitations is shown most distinctly in Fig. 1 of appellant’s drawing. As illustrated in the drawing,- the large end of the pear- is impaled on a spike -and- held between a pair of jaw members which, when clamped, encircle the large end of the fruit. The stem end of the pear extends beyond the holding means so formed into an encircling tubular sleeve aligned with the jaw members as clamped. The arrangement is such that when the device is operated a movable knife (described in the specification as a “bobbing blade”) passes between the clamped jaws and the encircling tube to sever the stem end, which end is later ejected from the sleeve by a plunger.

The Thompson et al. patent discloses a subcombination wherein the large end of a pear is impaled on a “spindle” and the stem end is engaged by notches formed in elements described in the specification as “scissorlike centering blades,” the notches (which in pat-entees’ preferred form have their inner-edges sharpened to cut into the neck of the pear) are in alignment with the spindle. The extreme stem end of the pear is shown projecting outside the notches. It appears that in operation the centering blades are closed upon the stem end of the pear so that such end is gripped in the notches and held in position and the device is moved so that the pear contacts a revolving circular knife (the knife being stationary relative to the other features of the device) which is so arranged that it severs the stem end at a point between the holding means and the notches.

In the Berrini patent,-designed for cutting off the small ends of eggs, an arrangement of parts is shown wherein the egg is placed in a holder shaped to conform to the shape of the egg. The small end protrudes from the holder into a device having a socket which fits over the end and it is severed by a knife arranged to pass between the holder and the socket. This device.seems to have been intended primarily for use as a'table utensil.

The examiner rejected both appealed claims as being unpatentable over either the Thompson et al. patent or the Berrini patent. The board expressed the view that both claims “are fairly met in the Thompson et al. patent,” but also held the Berrini patent to be a pertinent reference “In view of the broad scope of the claims.”

It does not seem' to be questioned that the impaling spindle of the Thompson et al. patent meets the requirement of the claims for “fruit holding means” applied to whole pears, but appellant contends earnestly that the notched blades shown by the Thompson et al. device for holding the stem éndnf the pear during the cutting off of the stem end may not be regarded as an anticipation of appellant’s means adapted to contactingly encircle the neck of the pear, which feature is specifi[920]*920cally described in claim 29 as a hollow member open at one end. He also contends that the stationary circular knife shown in the Thompson et al. patent is not an anticipation of his cutting means movable transversely of the stem axis which feature is described-in slightly different phraseology in both the appealed claims. Further, he contends that neither of the cited references discloses means (such as his plunger) for discharging the cut off end of the pear.

Appellant’s principal argument with respect to the Berrini patent (aside from insisting that it fails to disclose means for discharging the cut off end of the article) is, in substance, that the patent relates to an art which is not analogous to that with which the involved application is concerned.

That there are certain differences in structure between the subcom-bination shown in the patent to Thompson et al. and that of appellant here involved is obvious, of course, and these were recognized by the tribunals of the Patent Office.

From the brief filed by the Solicitor for the Patent Office before us we quote the following:

It is thought that these [the Thompson et al.] notched blades are fully equivalent to the “means adapted contactingly to encircle the neck of the pear” which are recited in claim 12 or to the “hollow member open at one end to receive and encircle the neck of the pear” set forth in claim 29. It is true that, in Thompson et ah, the inner parts of the notches are preferably sharpened and cut into the pear to some extent, but there would be no invention in omitting this sharpening and relying on a simple clamping action. In fact Thompson et al.
