Opinion

Hatfield, Judge,

delivered the opinion of the court:

This is an appeal from the decision of the Board of Appeals of the United States Patent Office affirming the decision of the Primary Examiner rejecting claims 15,16, and 22 in appellant’s application for [1313]*1313a patent for an alleged invention relating to improvements in fruit splitting apparatos.

Claims 15 and 22 are illustrative of the appealed claims. They read:

15. Fruit splitting apparatus comprising fruit severing means including means providing opposed surfaces disposed in the plane of the opposed surfaces of the fruit severing means and against which the cut sections of the fruit are adapted to lie after the cutting operation, means for for conveying a whole fruit into contact with the cutting means to sever the fruit and to convey the severed portions onto the said opposed surfaces, each of said opposed surfaces having a plurality of countersunk portions, the total area of the countersunk portions being relatively great as compared to those portions of the opposed surfaces which lie in the plane of the severing means whereby to prevent the formation of a vacuum between the said opposed surfaces and the cut face of the fruit so as to prevent sticking.
22. In a fruit-treating apparatus, the combination of a frame, fruit-conveying means adapted to travel along a horizontal, pathway at a predetermined level, from a fruit-feeding station to a spreader station, fruit-severing means disposed in the path of the conveying means for severing the fruit into sections, fruit-spreading means comprising opposed extended surfaces shiftable to one position to lie substantially vertically in the path of said conveying means to receive the severed sections thereon, movable fruit-holding means adapted to be moved into position adjacent the fruit-spreading means for receiving the fruit sections from said spreading means, and means carried by each spreading means adapted to contact with each fruit section as each fruit section is moved onto said spreading means for preventing each fruit section from shifting downwardly while said spreaders are in vertical position.

The references are:

Eldridge, 1,512,410, October 21, 1924.
Dorsey, 1,548,192, August 4, 1925.

The apparatus defined by the appealed claims is that particular part of a fruit treating machine called a “splitting device.”

As stated in appellant’s application, the apparatus defined by the appealed claims is so designed and arranged that it will “engage the flat faces of fruit being halved in a manner preventing lateral displacement of such halves during the remaining splitting and subsequent operations thereon.”

We quote the Primary Examiner’s description of the apparatus as follows:

The subject of the claims is a device for halving a whole pear and automatically delivering the halves to individual cups with the cut face facing upwardly. More specifically they are directed to the specific structure of the spreadable wings which deliver the halves to the cups. In operating the device, a pear from which the stem end has been bobbed is delivered directly beneath the carriage * * * and clamping jaws * * * and raised into position between the jaws. The jaws then move together and clamp the fruit * * *. The carriage then moves along the bars * * * and conveys the fruit through the vertical halving knife * * * and onto the vertically positioned abutting [1314]*1314wings * * *. The wings carry fins * * * on which the respective halves are impaled. The face of the wings are grooved longitudinally * * *, and transversely * * *. After delivering the halves onto the wings the jaws open and the carriage returns to initial position. The wings with the halves impaled thereon spread apart to a horizontal plane * * * and deposit their halves into * * * cups * * *.

The reference patents need not be described in detail as the issues involve only the countersunk portions or grooves of the spreading wings, as defined in claims 15 and 16, and means carried by the spreading wings for preventing the halves of the fruit “from shifting downwardly while said spreaders are in vertical position,” as called for in claim 22.

The patent to Eldridge relates to a fruit pitting machine, and the structure disclosed is similar to that defined by appellant in appealed claims 15 and 16, except that it does not disclose the countersunk portions on the outer surfaces of the spreading wings.

It is contended by counsel for appellant that the patent to Eldridge does not disclose the element or means carried by the spreading wings to prevent the fruit sections from shifting downwardly as defined in appealed claim 22.

The patent to Dorsey relates to a vegetable slicer, and discloses “longitudinally extending grooves * * * between which are ridges * * * upon which the fruit or vegetable * * * being sliced rides.” Relative to the longitudinal grooves on the spreader wings, the patentee states that they “serve both to reduce the friction of operation, and to admit air beneath the. unslioed part of the vegetable or fruit, thus preventing it from stiohing.” [Italics ours.]

As to claims 15 and 16, the tribunals of the Patent Office concurred in holding that it would not involve invention to provide the spreader plates, disclosed in the patent to Eldridge, with a plurality of countersunk portions to prevent the formation of a vacuum between the opposed surfaces of the plates and the cut face of the fruit so as to prevent sticking, in view of the countersunk portions in the spreader wings disclosed in the patent to Dorsey.

Relative to the means carried by the spreader plates to prevent the fruit sections from shifting downwardly while the spreader plates are in vertical position, called for in appealed claim 22, the Primary Examiner held that the patent to Eldridge discloses means carried by the patentee’s spreader plates to prevent the fruit sections from moving downwardly as they are moved onto the spreader plates and while the latter are in vertical position.

In its decision relative to the apparatus defined in claims 15 and 16, the Board of Appeals said:

The examiner lias field witfi respect to claims 15 and 16 tfiat it would not involve invention to place vacuum-breaking grooves on the fruit separator [1315]*1315blades 24 and 25 of Eldridge, particularly in view of the fact that grooves on the beds of vegetable slicers are old, as shown by Dorsey.
Appellant argues that in Eldridge it would be undesirable to break the suction as the fruit portions should be held in vertical position. He also contends that inasmuch as the cups * * * move the fruit portions longitudinally of the blades * * *, the suction-breaking grooves are not needed.
We are not convinced that it might not be desirable to place grooves on the spreading members of Eldridge as we believe that these members may start to operate almost before the fruit portions have moved away from the upper cup members * * *. Perhaps it is not evident that these grooves may be needed. We believe that it would not require invention to provide them if it was found that the fruit had a tendency to stick to the blades.
