Abstract
189,615. Dickson, J. Oct. 19, 1921. Yarns, warping &c.-In yarn-warping and like machines wherein provision is made for an extra permissible movement of the stop-rod in a stopping direction above that required for stopping the machine, such extra movement, if given, is arranged to take place against the action of 3 spring and to apply a brake for bringing the drum quickly to rest, release of the stop-rod after such additional movement permitting the spring to act to return the stop-rod a sufficient distance to release the brake automatically. In the form shown in Fig. 1, one part p<1> of the stop-rod telescopes into another part p and is held normally in the position shown by a spring q. When the operative moves the stop-rod to the left, the belt fork h shifts the belt on to the loose pulley g<1> by means of an arm o pivoted to the part p and mounted on a shaft n carrying a toothed quadrant m in gear with a wheel ! on a shaft k, which carries a crank-pin i in engagement with a part or the belt-fork h. When a sudden stoppage is required, the part p of the stop-rod is moved further to the left. The resistance of the spring q is then overcome, and a band brake v is applied through a cord s and lever devices. A spring v<2> tends to keep the brake out of engagement with the brake drum w. In the form shown in Fig. 3, the belt-fork h is operated by a swinging lever x carrying a bell-crank lever x<1>, which is pivoted to the stop-rod p<1> and is normally held in the position shown by a spring ta. When the stop-rod is pushed to the right, the belt is shifted to the loose pulley. If the stop-rod is pushed further to the right, the spring ta is, overcome and a brake is applied. Another method of providing for the extra permissible movement of the stop-rod p<1> is shown in Fig. 5, in which a pin on the lever x is normally held by a spring tb in the end of a slot p<2> in the stop-rod p<1>, the spring being overcome when the stop-rod is pushed through a distance more than sufficient to shift the belt on to the loose pulley. In a modification, certain parts are reversed so that the machine can be stopped by pulling the stop-rod. In the form shown in Fig. 6, a collar y loose on the stop-rod and adapted to be connected to the belt-shifting mechanism is held in the position shown by a spring tc. When the stop-rod is pushed beyond the position for shifting the belt to the loose pulley, the spring is overcome and the further motion of the stop-rod applies a brake. In a modification, the parts are arranged for use with a stop-rod that is pulled to stop the machine. In another form, a lever z, Fig. 8, on a spindle z<1> of the belt-shifting mechanism has a pin z' movable in a cam-slot p<4> on the end of the stoprod. Extra permissible movement of the stoprod for applying the brake is provided for by arranging a straight extension p<5> in the cam-slot. In a modification, the stop-rod carries a pin working in a partly inclined and partly straight slot in a movable plate connected to the beltfork. The straight part of the slot allows for the extra permissible movement of the stop-rod. In each case, a spring is employed to bring the parts back into normal position after the extra movement has been given to apply the brake.
