Abstract

1,018,476. Threading nuts. L. SCMIDT, W. LOOS and C. LOOS MUTTENFABRIK, [trading as LOOS & SCMIDT]. Sept. 3, 1962 [Sept. 4, 1961; May 8, 1962], No. 33655/62. Heading B3N. An automatic thread cutter comprises a hollow stationary guide 2 mounted on the frame 1 with a rotatable tap 5 and a displaceable second guide 3 mounted on a carriage 11 for reciprocation by a cam 7 (Fig. 1, not shown). Nuts 4 to be threaded are located in a magazine above the guide 3 and are brought into contact with the tap 5 by a feed slide 9 which moves in conjunction with the carriage 11 under the action of cam 7. A rail 14 attached to the slide 9 is provided with adjustable stops 15 and extends through the carriage 11. In operation a nut entering the guide 3 from the magazine is moved into a feed aperture by the slide 9. Abutment of the stop 15 with the carriage 11 facilitates movement of the carriage with the guide 3 and nut up to the rotating tap 5. When thread cutting commences in the nut the pressure thereon by the slide 9 is controlled by changing weights 8, 8a in co-operation with an adjustable stop 17. As the threading operation continues the carriage 11 moves in front of the stationary guide 2. At this stage the nut is drawn out of the guide 3 into the stationary guide 2 and is subsequently east off over the tap 5. The slide 9 and carriage 11 return to their initial positions for the commencement of the next threading operation. In an alternative embodiment a spring-loaded lever is provided on the carriage 11 which co-operates with the stop 15 on the rail 14. This operates in conjunction with a holding cam to control movement between the slide 9 and carriage 11 to ensure that the carriage with the nut only moves towards the tap 5 when correctly located in the second guide 3.
