ing a machine when the bobbins are full,
thereby ensuring that each dotting shall be of uniform weight and length; and the invention has for its objects, to overcome the present difliculty in starting up a machine, to
provide a less costly and less complicated motion capable of being installed in a smaller space than the existing type, to enable a frame to be started up in the ordinary way without interfering with the setting of the stop mo tion, and to permit the stop motion at one side of a frame to be operated independently of the setting of that at the opposite side.
In existing stop motions operating through the medium of a coarse starting screw the belt is liable to be strained, and when a double thread screw is employed (as is commonly the case) difficulty in starting up is experienced. The use of this coarse thread or of a double thread is now obviated.
According to the invention the starting rod of spinning, twisting and like frames is engaged, while the frame is running, by a retaining catch controlled bya flexible connection coupling it to a member of the knock-off motion and adapted to be released thereby at a predetermined time to permit the starting rod to move to shift the driving belt or otherwise to arrest the machine.
In its preferred form the invention embodies a spring-controlled retaining catch which may be borne pivotally by the sliding member adapted to travel as a nut on the fine threaded rod supported in a bracket fixed to the frame and provided with an operating hand-wheel, whilst a flexible connection such as a chain or a Bowden wire may connect said retaining catch with a lever mounted pivotally in the path of a projection on a member of a spool-type knock-oft motion, or, alternatively, said chain or wire may be connected to the lever of a length-type knockoff motion.
Also, in the preferred form, the end of said starting rod may be formed with a notch, lug or the like, adapted to be engaged directly by the aforesaid retaining catch which, when Serial No. 219,304, and. in Great Britain September 20, 1926.
the sliding member is travelled as a nut by operating the aforesaid hand wheel, serves to draw the starting rod into the starting up position.
One constructional embodiment of the in vention as applied to a worsted spinning frame is illustrated by way of example in the accompanying drawings, in which, Figure 1 is an end view, Figure 2 is a side elevation, and Figure 3 is a plan view, only such parts of the frame as are necessary for describing the function of the invention being shown.
A is the longitudinally movable starting rod connected to and operating the belt fork A and harnessed to a spring A suitably anchored to the main frame of the machine (or if desired, to a weight instead of a spring), and A A are respectively, the fast and loose pulleys mounted on the main driving shaft A The starting rod A is supported near its outer end by an eye A connected to a bracket A secured to the endstand K, and said starting rod is formed with a hooked extremity A adapted to be engaged by the nose of a catch B mounted pivotally at B upon a projecticn or horn B springing from an internally screw-threaded block C adapted to work as a nut upon a finely threaded rod D supported rotatably in bearings D D and at its outer end carrying an operating hand-wheel D The block G is formed with a base C resting on and adapted to slide along the upper surface of the bracket A The horn B terminates in a pair of apertured ears B B between each of which and the body of the catch B a spring B is confined, and into each of said ears B is screwed a sleeve or gland B supporting one end of the flexible casing B of a Bowden wire B that end of which is sweated or otherwise suitably secured to the catch B.
The casing B containing wire B is carried from each of said ears B down the endstand K through supporting clips, lugs B or otherwise suitably, and is secured to a sleeve or gland B fixed in a bracket B bolted to the main framing, the extremity of the wire B being sweated or otherwise suitably attached to a trip lever E pivoted at E to the running position and remain so until bracket 13 and projecting into the path of movement of a stop or projection F carried by a longitudinally movable member F of the traversing lifter mechanism and func tioning as a spool-type knock-off motion. The connections from B to E and the parts F, F are of course duplicated although omitted in the drawings.
Instead of connecting the lower end of the Bowden wire B or its equivalent to a spooltype knock-off motion as shown, the wire may be connected to the gear-operated lever of a length-type knock-off motion, as will be well understood.
In operation, when the machine is standing the belt fork A would be over pulley A and the hooked end A of the starting rod A would be adjacent to the supporting eye A".
- In order to start up the frame the handwheel I) is turned so as to travel the block C along the finely threaded rod 1) until the catch B is engaged with the hooked end A of rod A. The movement of hand-wheel 1) is then reversed and rod A is drawn by catch B longitudinally to the left, transferring the driving belt slowly from loose pulley A to driving pulley A When the block C reaches the end of its sliding movement to the left the parts are in the time arrives for the lever E to be struck by projection F thus pulling wire 13 and releasing catch B from the hooked end A Immediately catch B is withdrawn the rod A moves under the influence of spring A to the right and transfers the belt to loose pulley A thus stopping the frame.
Until the bobbins are full and the frame is knocked-off the hooked end of the starting rod and the spring-controlled catch remain in engagement, and if necessary, during the intervening period such as at meal times, the frame may be stopped and restarted in the ordinary manner.
The invention is obviously applicable to machines other than spinning and twisting frames.
