Decca Record Cleaner
Over the years many people have given much time, thought and labour to finding a solution to the dust and static problem of the gramophone record.
The most notable is perhaps Mr Cecil (Dust Bug) Watts, who pioneered work on a clean disc many years before most people even realized that there was any great problem.
In his classic patent No.817598 as early as 1957 he states the problem and outlines his solution to it:
A known cleaning device comprises an arm carrying a brush of suitable material adapted to engage the sound grooves and track along them and a pad of suitable fibrous material adapted to sweep the surface of the record.
The material of the brush is such that its fibre can enter the sound groove and does not appreciably abrade it; nylon fibre is suitable.
It has been found that with this device difficulty is sometimes experienced owing to static charge developed upon the record surface by friction with the reproducing stylus or the brush or the cleaning pad.
This charge tends to attract dust particles from the air. Moreover when the brush dislodges dust particles from the groove these particles tend to fall back into the sound groove owing to electrostatic attraction.
According to the present invention there is provided a cleaning device for a sound record comprising an electrically conducting arm carrying a brush and a pad of suitable fibrous material electrically conducted to the arm.
Thus in use the pad itself is rendered electrically conducting, for instance by moistening it with water, and then dissipates any static charge that may develop.
Watts found that if the brush was sufficiently stiff to remove the particles, the nylon fibre was too thick to enter the groove correctly.
With characteristic thoroughness he devised a method to radius each tip. Various other devices have been conceived and marketed which tackled the problem with varying success.
A real breakthrough presented itself when a small new company, Chelston Audiocraft Ltd, approached Decca Special Products. Chelston Audiocraft had been working on the problem for some time and found a new material which offered a simple solution. The new man-made fibre was only microns in diameter yet incredibly strong - and was conductive.
A small brush made from the new material is extremely effective not only in reducing the static but in searching out even the finest of abrasive dust often left in the groove by other cleaning devices.
The Decca Record Cleaner consists of an electrically conducting arm, wired to earth, carrying a brush made from this new fibrous material.
The record has usually been technically in advance of the means of reproducing it - the Record Cleaner helps us towards realizing its full potential.
With the freedom from irritating and distracting noises there is no doubt that the serious music listener will find it of immense value.
Those who count the cost can also be assured that as well as the immeasurable additional pleasure they will experience they can also be happy in the knowledge of the product paying for itself over and over again in reduced record and stylus wear.
