This patent number is seen on the Jefferson Golden Minute, Golden View, Golden Helm, Golden Secret, Exciting Hour and Golden Hour (except for early and late ones). The patent was not issued to Jefferson. The clock described in the patent was not made by Jefferson.
Application number 645,998 was filed on February 7, 1946 but it was abandoned. Application for a new patent, serial number 101,510, was made in France on September 10, 1948 and in the United States on June 27, 1949. On June 23, 1953 the patent was issued to Leendert Prins.
The patent describes the clock in great detail with 3 pages of illustrations. The round dial, glass and hand assembly is mounted on a wooden base. The motor is mounted vertically and protrudes from the rear of the clock. It has advantages over the earlier Prins patent.
It incorporates a
single transparent disc with a minute hand frictionally attached to it that
drives the hour hand by gears and a weight. It is improved over the two-disc
clock for ease of setting the hours and minutes independently. The patent
further describes: "....the single disk itself may be omitted and the
minute hand connected to the rotating gear which is mounted in the clock frame
and masked from view thereby.....and yet the illusion of a mysterious drive is
retained or even heightened...." The inventor's address is
The name plate on the
bottom of the clock says Etalage-Reclame corporation,
It is 9-7/8" high, 9-1/2" wide and 2-1/4" deep. Weight is 2 lbs. The lacquered solid walnut base is 7-1/2" wide, 2-1/4" high and 1-3/4" deep. The front and back of the wood is angled in at about 15 degrees. The sides are angled at 60 degrees. There are four 1/4" diameter brown felt pads on the bottom in the corners. The outer ring appears to be gold plated. It has rounded depressions about 1/16" deep and 1/4" in diameter to indicate the hours of 3, 6, 9 and . The remaining hours have rounded depressions about 1/32" deep and 1/8" in diameter. A retaining ring holds the glass disk in the frame. Three small lugs are equally spaced around the rear of the frame. The retaining ring may be resiliently snapped into position to hold the disk.
The minute hand is located in front of the glass and is attached to it by friction so that it can be easily turned to set to the desired minutes. The hour hand and gear assembly is located behind the glass. A shaft attached to the center of the glass has a gear on it that's in the counterweight gear assembly. The counterweight always stays in a vertical location from gravity. It provides a fixed position needed to drive other gears that advance the hour hand as the glass turns.
The picture shows the rear of the hands and the pear shaped counterweight assembly. There's also a counterweight at the end of the hour hand and can be seen near the top left of the picture. It serves to hold the hour hand in proper position relative to the minute hand. The hour and minute hands are about 3/16" wide. They have a slot about .038" wide for most of their length. The wide portion is gold colored and the thinner portion is light beige. The back of the hands is also light beige.
The clock is powered
by a synchronous motor made by Haydon Mfg. Co,
