Ever stub a putt? Thomas Black received a British patent (No. 11,463) dated May 20, 1902, that covered this double roller-sole putter that was designed to prevent such a result.  In his patent Black states that his rollers would “prevent the stroke of the club being spoiled by the head or sole of the club coming into contact with the ground or turf before reaching the ball, such a stroke being commonly known as ‘duffing.’ “

Black’s roller sole clubs were made by J&A Dickson of Edinburgh. As can be seen in the accompanying images, the sole is fitted with a metal plate that contains two metal cylinder rollers.  These clubs met with little acceptance. Few remain.  

The top of the head is stamped “Black’s Patent No. 11,463.” The finish is original as is the 36 1/2" shaft and leather-wrapped grip.  Both rollers in the sole rotate freely.  Overall this club is in excellent, solid condition and all there.  This is one of the best mechanical clubs a collector can acquire.
