    • 25,800. Longworth & Co., and Shaw, P. Nov. 11. [Cognate Application, 9526/13.] Heckling-machines; feeding and transferring flax &c.-Mechanism is provided for automatically unfastening and re-fastening flax holders, such as those described in Specification 21,422/12, the plates of which are held together under pressure by reason of sliding pieces on one of the plates engaging with parts on the other plate, and for opening the plates for the purpose of removing, replacing, or readjusting the flax therein, the arrangements ensuring that the holders will hold the flax with a greater uniformity of pressure than hitherto. Fig. 1 shows the feeding end of the machine with a part b of the cross channel arranged to be raised and lowered for the purpose of removing and replacing the stricks of flax, the top plates d of one or more of the holders being held in the raised position by a fixed slide P engaging with projections on the plates. For the purpose of unfastening and re-fastening the holders, the latter, while supported by fixed portions of the cross channel, are pressed by spring or weighted plungers E, and the sliding fastenings d are moved in one direction or the other by levers e, e', f, f respectively. The parts are operated by cam-and-lever mechanism, which may be specially provided for the purpose, or the motion may be obtained from the shaft h commonly employed for actuating the turntables. A suitable system of levers for operating the plungers E is shown in Fig. 2. The first effect of the rocking of the shaft g' is to cause the lever g to turn about the pivot g on the end of the spring rod g and to bring the plungers E down upon the holders; further rotation of the shaft g causes the holder plates to be firmly pressed together owing to the turning of the lever g about the pivot g and the resistance of the spring rod g . The levers or fingers e, e , f, f are connected by spring rods e , f2, f with an operating-lever h , the fingers e, e being also connected together by a link e as shown. The sliding fastenings d may be clamped in their disengaged position when the holders are supported on the rising and falling part b of the channel, by means of clamping-levers M, m, m , m , Fig. 3, which are connected together as shown and operated by studs or projections n, n on the catch-bar N. Guides K are provided to prevent the bottom holder plates d' from being moved out of position as they descend. At the charging end of the machine, the holder plates may be opened the short distance required (1) by raising the top plate as it is held in the slide P by means of a spring lever operated from the shaft h , which also operates the pull-through mechanism, the parts being so arranged that, as the plate is raised, the flax is drawn through the holder, and as the pull-through mechanism is released, the top plate is lowered against the action of the spring; (2) a part of the cross channel may be severed from the remainder and arranged to be lowered together with the bottom plate of the holder for a limited distance, the upper plate of the holder being held in a fixed slide; or (3) a part of the cross channel may be arranged at a lower level than the main parts thereof and connected by inclines to them, so that, the upper plate of the holder being supported, the lower plate moves to the lower level and is again raised as it moves along the cross channel.

Heckling-machines; feeding and transferring flax etc.; gill boxes.-In apparatus of the class described in Specification 2876/09 for automatically transferring the stricks of flax from a heckling-machine of the type described in Specifications 17,437/99, 16,010/01, and 19,300/07, to a spread-board, gill frame, or tipple stool, the stricks are seized by a pair of grippers and removed from the holders and are received by a second pair of grippers which lay them upon a table or a tipple stool. The strick x, Fig. 2, is withdrawn from the holders b in the crosschannel B' of the heckling-machine by a pair of grippers D, E. The gripper D is carried by an arm D mounted upon a lever d and operated through a connecting-rod d and lever d by a cam on the shaft K. This gripper as it rises presses the strick x against the other gripper E, which is carried by an arm E' mounted upon a lever e , and moving the gripper E against the action of the spring e draws the strick out of the holder. The grippers D, E, which are counterbalanced by a weight W at the end of a strap w, carry the strick over to a second pair of grippers F, G carried by arms F , G loose on a shaft F and operated by cams on the shaft K through connecting-rods and oscillating quadrants gearing with spurwheels f , g , Fig. 4, on the bushes on which the arms carrying the grippers are mounted. These grippers lay the stricks upon a table c, upon which they are acted by a rotary wiper or spreader H, comprising a curved plate carried by rotating arms h. The stricks are moved along the table c to the rollers C of the spread board. The ends of the strick are removed from the holder b by a spring-controlled blade P operated by a bowl on the end of the arm E engaging a lever p fixed to the same shaft p as the arms p carrying the blade P. The transfer apparatus is driven from the heckling-machine, so that it may work in harmony with it by means of a chain K , Fig. 2. The cam shaft K is driven through gearing k , k , k , k , k , k . The spread-board is driven from the transfer apparatus by a chain from a sprocket-wheel t, mounted upon a shaft N driven from the gear k through spur gearing t , t , and variable-speed gearing m ... m , n ... n . The speed of the spread-board is varied to give the required overlay of the successive stricks by means of a change wheel t , while the speed is varied in accordance with the length of the stricks of flax by the variable speed gearing. The gears n ... n are loose on the shaft N, and anyone of them may be connected thereto by a sliding key n operated through linked levers O, O by a handle moving over a segment o provided with holes o ... o , which are engaged by a spring projection on the handle, and which correspond to the various required positions of the key n . The sprocket-wheel t through which the spread-board is driven is connected to the shaft N by a clutch N . This clutch is put out by a weighted lever Q, normally held out of contact with a cam-face on the clutch, but capable of contacting with it and opening the clutch when released by the action of a foot lever Q . The clutch is put in again automatically at the next lift of the heckling-machine by a cam R which engages a link r and lifts the lever Q into its normal position again. If the heckling-machine is intended to work for tipples for the store, the table c is removed and the grippers F, G deposit the stricks upon the tipple stool. A suitable guide may be provided to facilitate this.

    • 1480. Greeves, J. & T. M., and Shaw, P. Jan. 20. Heckling-machines. - In machines of the type described in Specification 13,699/03, in which the flax - holders are moved continuously through the machine and in which the heckle bars are moved endways in slides on the carrying - leathers, to follow the movement of the holders, the reciprocation of the heckle bars is obtained from camsurfaces arranged in such a way that their inclination can be adjusted to give a slower or quicker traverse. The ends of the heckle bars engage a cam-surface D pivoted at its upper end to a bracket d and connected at the other end, through a link d and lever d fixed on a shaft d , to a lever E pivoted to a quadrant bracket e. The lever E has an extension e , which moves over a scale on the bracket e graduated to correspond with the various change-wheels w which may be used to vary the speed of the heckle sheets in accordance with the fibres being treated. The cam-surface D is connected bv a link d to a corresponding surface D at the other end of the machine, arranged to give the return movement of the bars. In addition, surfaces D , D are arranged to operate the bars on the other heckle sheet, and are connected by a lever d and link d to the shaft d . The lever E is connected by a link e to the.pivoted bracket W , which carries the change-wheel w , so that, when the lever E is moved to alter the inclination of the cam surfaces, the bracket W is also moved into such a position that only the particular change-wheel which gives the desired speed can be inserted. The adjustment of the cam surfaces may be made to depend on the speed of the holders passing through the machine, the speed of the heckle sheets remaining constant. The cam surfaces may be arranged so that the traverse of the heckle bars occupies the whole of the time of the descent, the return movement taking place during the ascent. To ensure as small a radius as possible for the throw of the heckle pins as they pass over the top rollers, auxiliary bars C', Fig. 4, are secured to leathers H, and pieces G are attached to the backs of the bars C' to form, with the bars C, guides for the heckle bars in the same plane as the surface of the leathers.
