Abstract

449,916. Bushing internal screwthreads. STREIT, A. P., 47, Route d'OrlÚans, Cachan, France. Feb. 7, 1935, No. 4011. Convention date, Feb. 7, 1934. [Classes 83 (iii) and 83 (iv)] [See also Groups XXV and XXIII] The screw holes for chair screws are bushed by inserting a metal helix 1 of V crosssection. This helix is formed by securing a malleable strip in the hole 8 of the mandril 4 and then passing the mandril and strip through the die 10, thus pressing the strip on to the thread 5. The bush is then inserted into the work whilst still on the mandril but a backward turn causes the bush to grip the sides of the hole, breaks the strip at the hole 8 and thus allows the mandril to be withdrawn. Various locking devices associated with the hole 8 are described.
