Abstract

679,970. Darts. ESCOMBE, G. G. Jan. 12, 1951 [Oct. 21, 1949; Jan. 10, 1950], Nos. 27081/49 and 621/50. Class 132 (iii). A dart comprises a hollow body in the interior of which is a mass which is free of the body in respect of rotation axially of the dart. In Fig. 1, a light weight dart body 1 is hollow and contains a cylindrical weight 2 which is freely rotatable on a rod 7 formed into a point at 6. The impact of the dart on the board is reduced by a helical spring 12 between a forward bush 4 and the weight 2, and a rear bush 5 is bored to receive a spring clip which secures a flight 3. A blank 13, e.g. of metal or plastic, is formed . into the flight. Modifications comprise a semi-cylindrical weight 2, and the body of the dart may be filled with a liquid e.g. mercury, Fig. 4 (not shown). The first Provisional Specification also describes a weight fixed to a spindle that is rotatable relative to the dart body.
