506,176. Darts. THROUPE, J. W. Nov. 24, 1937, No. 32323. [Class 132 (iii)] The body part 6 of a dart is formed hollow to receive the point 4 and flight-holder 7 when the dart is not in use. The body part is internally screw-threaded and slightly tapered at each end, and normally receives the flightholder and point in the manner shown in Fig. 2. When the dart is not in use, the point and flight-holder are detached from the body, reversed, and stored within the body in the manner shown in Fig. 3. A case may be provided to hold a set of three collapsed darts and folded flights therefor.
