Abstract: 367,852. Locking-mechanism for stopmotions of spinning, twisting, and like frames. MACKIE & SONS, Ltd., J. and MACKIE, J. P., Albert Foundry, Belfast. Nov. 21, 1930, No. 35131. [Class 120 (ii).] In a spinning, twisting or like frame having a stop-motion of the type in which a feeler normally supported by the yarn is allowed on breakage of the latter to fall into the path of a power-driven actuator which directly operates the stop-motion, locking-mechanism is provided connected to the starting and stopping gear so that the actuator is automatically put out of action before the frame is stopped and is prevented from coming into action immediately on re-starting the frame. The locking-mechanism may also be operated by hand without affecting the running of the frame. The actuator shaft 2, Fig. 1, is oscillated by the engagement of a star-wheel 1 with a roller 5 adjustably carried in a slot 7 by the arm 3 of a two-armed lever 3, 4 the upper end of the arm 3 being formed as a hook 8. A lever 9 pivoted to the frame at 10 is provided with a hook 11 adapted to engage the hook 8 and hold the arm 3 clear of the star-wheel 1 so as to render the stop-motion ineffective. The machine is stopped by moving the starting lever 12 upwards the arm 13 and jockey-pulley 14 thereby being swung clockwise and the driving- belt 15 running idle. The levers 9, 12 are connected by links 16, 17 pivoted together at 18, the link 17 being pivoted at 10 and abutting against a pin 21 on the tail 20 of the lever 9. When the lever 12 is lifted to stop the machine the link 16 is raised, the link 17 moved about the pivot 10 and the lever 9 allowed to fall under gravity, the hooks 8, 11 then engaging to lock the shaft 2. The lever 12 is adjustably connected to the arm 13 by a bolt 22 in a slot 23 and is so arranged that the shaft 2 is always looked before the drive is stopped, and, on restarting the stops 19 provide lost motion to ensure that the drive is started before the shaft 2 is released. The arrangement may be made semi-automatic by omitting the lower stop 19, the stop-motion being automatically locked on stoppage of the machine and remaining locked on re-starting, the lever 9 being subsequently released by hand. In a modification having a rotating actuator, the shaft 2, Fig. 2, is driven from a constantly rotating gear-wheel 24 through an idler 25 and a gearwheel 26, the wheel 25 being carried by the arm 28 of a three-armed lever 27, 28, 29. On stoppage of the machine the link 16 is lifted, the idler 25 disengaged and the parts locked in position by the engagement of a pin 30 on the arm 29 behind a projection 35 on a latch-lever 31. On re-starting the machine the latch 31 is lifted by hand to reset the device. It may be made automatic however by providing a pin 47, Fig. 3, on the link 16 to rock the latch 31 and release the pin 30 when starting the machine, the idler 25 engaging the wheels 24, 26 under the action of the weight 48. Specification 358,937 is referred to in the Provisional Specification.

[Also in Division F2] A fastening device for safety belts for vehicle passengers comprises two pivotable jaws 3, 4 and a stud 9, the jaws being normally open and adapted which are biased to their unfastening position and which move to close upon the stud 9 when the stud is introduced between the jaws, the jaws being retained in the closed position by a pivotally mounted lever 15 which is biased resiliently towards the jaws and which is provided with surfaces 17a, 17b which are of arcuate shape and which are centred on the pivoting axis of the lever. The jaws are biased towards their open position and the lever 15 is biased towards the jaws by a common spring 13 one end of which engages a pin 16 on the lever 15 and the other end of which engages a pin 12 on the jaw 3. The jaw 4 is moved by a tooth 10 on the jaw 3 which engages a notch 11 in the jaw 4. When the stud 9 is introduced between the jaws it engages portions 7a, 8a of the jaws and moves the jaws against the bias of the spring 13 so closing the recesses 7 and 8 together and separating surfaces 18 and 19 of the jaws to such an extent that a tooth 17 on the lever which includes the surfaces 17a, 17b can move between the surfaces 18, 19 to hold the jaws in their closed position. To limit pivotal movement of the jaws to their closed position the jaw 3 abuts against the hub 15a of the lever 15 and the jaw 4 has a tooth 20 which abuts against a portion of a casing 21 which carries the two jaws. The casing 21 has a slot 2a which receives one end 1a of a belt and the stud 9 is carried by a yoke 29, Fig. 2, which is part of a buckle 25 a sliding bar 26 of which receives the other end 1b of the belt. The provision of the arcuate surfaces 17a and 17b allow the jaws to be easily released by movement of the lever 15 by a button 23 and so makes the fastening device suitable for a vehicle safety belt.
