Opinion

O’Connell, Judge,

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 the action of the Primary Examiner in rejecting all the claims in appellant’s application for a patent relating to an apparatus for testing and charging storage batteries of the type commonly used in motor vehicles.

[1182]*1182Of the five appealed claims, Nos. 12, 13, 14, 15, and 21, appellant hag moved to dismiss the appeal as to claims 13, 14, and 15. The. motion will be granted thereby limiting the appeal to the remaining claims, 12 and 21.

The references are :

Oestermeyer, 2,098,131, October 19, 1937.
Clieeseman, 2,246,163, June 17,1941.
Amsden, 2,227,118, December 31, 1841.
“Experimental Electrical Engineering” (KarapetofC) Vol. 1, 2nd Ed. 1910, pages 403 and 404 — John Wiley & Sons, New York.

Claims 12 and 21 read as follows:

12. Battery testing apparatus comprising, a load circuit having a predetermined fixed resistance adapted to discharge a battery at a normally high rate, a meter circuit connected to the battery terminals, a switch for closing said load circuit and a galvanometer included in said meter circuit, and calibrations and legends on the face of said galvanometer, said calibrations being placed thereon in predetermined relation to said fixed resistance to thereby indicate without further reference the time required to charge said battery at a predetermined high rate, said galvanometer being operative when said switch is closed.
21. Battery testing apparatus comprising a battery load circuit, a switch for closing said load circuit, said switch being biased to opened position and manually closable against the bias, a resistance in said load circuit having an ohmage value substantially equal to that of a starting motor, a galvanometer carried across the battery terminals when said switch is closed, said galvanometer including calibrations and indicia for directly determining without the necessity of calculations the time in minutes during which the battery may be charged at a high rate without injury thereto.

. Appellant’s complete apparatus, which is intended to test and charge the battery without removing it from the automobile, includes a battery charger.

But only the testing part of the apparatus is here involved. That part comprises a load circuit, including a fixed or predetermined resistance adapted to discharge the battery to.be tested. One terminal of the battery is adapted to be connected in the testing and charging-circuits by two leads and the other terminal is adapted to be connected in the same circuits by two other leads.

The fixed resistance is adapted to discharge the battery at a normally high rate when the load circuit is closed with the aid of a manual switch or push button, spring biased to open position.

A meter circuit includes a combination voltmeter and ammeter instrument, defined by the claims on appeal as the “galvanometer,” which is connected to the terminals of the batteries to be tested.

The dial of the galvanometer has calibrations and indicia, that is, a time indicator scale and legends, so related to the fixed load circuit as to indicate, without any calculations on the part of the operator, the [1183]*1183exact and predetermined number of minutes required to properly charge tlie particular battery at a predetermined high and safe rate.

The voltmeter scale of appellant’s testing zone and its relation to the issue here involved was discussed by the Board of Appeals in the following excerpt from its decision:

Great emphasis is placed by applicant on the fact that the galvanometer scale is calibrated to give reading, not in terms of volts or amperes but in terms that will give practical information to the operator or to the car driver. This is done by using the left half of the scale (the “Testing Zone”) for voltage readings, calibrated in terms that show three possible conditions of the battery, the sections (reading from left to right) showing: (1) worn out or sulfated; (2) partially charged and capable of being recharged; (3) fully charged. The middle section (2) is further calibrated- in terms of minutes that -would be required to recharge to about 90% of the battery’s capacity at a high-amperage rate. [Italics not quoted.]

Although the examiner enumerated other grounds in the rejection of claims 12 and 21, the only ground of such rejection affirmed by the board was that the claims were not patentable over the disclosure of the Karapetoff reference in view of the Oestermeyer patent, and also as unpatentable over the Oestermeyer patent alone. Accordingly, it is deemed unnecessary to here discuss the reference patents to Amsden and Cheeseman.

The disclosure by Karapetoff in the publication, “Experimental Electrical Engineering,” relates to the testing of electric batteries. Connections are disclosed for the test of a storage cell, the. load circuit of which includes an adjustable resistance, for discharge, a double-throw switch, and a voltmeter connected across the terminals of the cell.

More particularly, the disclosure of the Karapetoff publication relates to experiments to be performed by students in a laboratory as to the. charge and discharge characteristics of an electric battery, with no specific reference to the batteries of an automobile. In conducting the experiment, the cell under test must be fully charged before beginning the experiment on the discharge characteristics, and “The time of charging should not be less than, three hours if the cell has been completely discharged.”

The patent to Oestermeyer relates to testers for various circuits and pieces of apparatus in the electrical system of a motor vehicle, including a test for measuring the voltage of the different cells of a multi-cell battery from a single voltmeter without changing the conductor connections from the battery to the test equipment.

A two-range voltmeter and a two-range ammeter are mounted on an instrument panel. On the dial of the voltmeter an inscribed scale is divided into the four headings, “Inoperative,” “Low,” “Fair,” and [1184]*1184“Good,” “which,” as stated in the specification, “are placed there particularly for the information of owners whose batteries are being tested.”

The readings on the voltmeter are quickly obtained and are .taken preferably under full load, that is, while the starting-motor is running. The patentee’s specification also calls for the use of a push-button switch in the operation of his device.

The concurring decisions of the tribunals of the Patent Office dealt largely with the rejection of appellant’s claims for method, which are not now before the court. The examiner held that claims 12 and 21 were unpatentable over the disclosure of the publication by KarapetoiT in view of the patent to Oestermeyer; that they were also unpatentable over the disclosure of the patent to Oestermeyer, standing alone; and were further unpatentable for the reason that they are clearly aggregative.

The Board of Appeals in affirming the decision of the examiner discussed his position relative to the subject matter of the appealed claims and set forth its own position with reference thereto.
