Patent No.2196/09, of January 29,1909, was granted to the Premier Manufacturing Co. (makers of Clarion cylinders) and F.W.Pleasance. The device is mounted on a steel plate pivoted on the existing feedscrew bearing, and introduces an addition pair of wheels between the mandrels and intermediate wheels when lowered for the '4-minute' position.
The Walshaw stylus (the subject of Patent No.2332 of February 1 1909 - not granted because the sealing fee was not paid) has two styli mounted in a revolving head on an otherwise conventional stylus bar, enabling any existing Edison reproducer to be used with little modification. Walshaw subsequently produced the ingenious 'Variol' attachment to provide 4-minute feed on Gems. The closeness of the Premier gear and Walshaw stylus patents (they are consecutive numbers in the Phonograph Class list) suggests a degree of collaboration at this early stage.
The present example was sold by Reading & Munton of Walworth Road, battersea Park Road and Camberwell Green, address within easy reach of the Premier Manufacturing Co. at Walworth.
