Okla. Stat. tit. 20, § 1311

When the court fund in any county becomes so exhausted that it appears that a party cannot procure an immediate trial by jury, the Administrative Director of the Courts upon the request of the presiding judge of the judicial administrative district and upon the approval by the Chief Justice of the Supreme Court, shall transfer from the Supreme Court Revolving Fund to the court fund of said county an amount that will be sufficient to permit an immediate jury trial of all cases that are triable by a jury and that are ready for trial.
