Abstract
717,353. Darts. KIRK, A. S., and FAREBROTHER; H. B. March 20, 1953 [April 3, 1952], No. 8574/52. Class 132(3) A dart flight comprises a solid shaft portion of rearwardly tapering form. whose front and larger end is socketed or spigoted to receive or fit in a separate metal spigot portion of less diameter than the front end of the flight shaft, the spigot portion being externally screw threaded to screw into a bore or recess in the rear end of a dart body. In Fig. 2, a spigot 4 has a threaded portion 6 for screwing into a. dart body, and a threaded part 5 engages in a bore in a flight shaft 1. If the shaft 1 is of plastic, the shank of the spigot 4 may be moulded into the shaft. The shaft 1 of the modification shown in Fig. 5, has an integral spigot 9 on which is screwed a threaded sleeve 8 for fitting into the dart body. Instead of being screw threaded, the inner bore of the sleeve 8 may be left smooth and forced on to the spigot 9. Similarly, the shank of the spigot shown in Fig. 2, may be left unthreaded for a friction fit in the shaft 1.
