Okla. Stat. tit. 38, § 19
Said officer shall write or cause to be written the names of all persons who are known to be qualified jurors under the law on separate cards of uniform size and color, writing also on said cards, whenever possible, the post office address of each juror so selected, the expense thereof to be paid from the court fund of each county, said names and addresses of such qualified voters to be typed upon the cards as herein described under the supervision of the court clerk. The cards containing said names shall be deposited in a circular hollow wheel, to be provided for such purpose by the board of county commissioners of each county after they have examined the contents thereof and removed therefrom and destroyed any cards found therein. Said wheel shall be in the form of a drum made of iron or steel and shall be so constructed as to freely revolve on its axle and big enough to freely mix all the cards placed therein, the size thereof in each to be determined by the number of names placed therein and shall be kept locked at all times, except when in use as hereinafter provided, by the use of two separate locks, so arranged that the key to one will not open the other lock; and said wheel and the clasps thereto attached into which the locks shall be fitted, shall be so arranged that said wheel cannot be opened unless both of said locks are unlocked at the time the wheel is opened. The keys to such locks shall be kept, one by the sheriff and the other by the court clerk. The sheriff and the court clerk shall not open such wheel, nor permit the same to be opened by any person, except at the time and in the manner and by the persons herein specified; but said sheriff and court clerk shall keep such wheel, when not in use, in a safe and secure place where the same cannot be tampered with.
