Definitions

  • the Object of the invention is to provide a novel method of and means for bringing the fibrous material into the formation of parallel or substantially parallel lengths, and, while in this formation, rapidly feeding it forward, as successive lengths, ready for incorporation in the fabric during the course of manufacture.
  • the material is passed to the helical convolutions of rotary screw or equivalent feeding devices in such manner as to pass to-and-fro in lengths between the devices.
  • the devices rotate they automatically bring the material, fed from a source or sources of supply, into substantial parallelism and,"at the same time, feed it v side-by-side and one after the other, to the place'of discharge ready to be incorporated either directly or indirectly in the fabric being manufactured.
  • Material from one or more'sources of supply maybe formed into loops which are fed forward in substantially parallel formation to the place of discharge.
  • the material may be presented to means which form the same into substantially parallel loops open at one end, the loops being fed forward by the helical convolutions of the rotary feeding devices.
  • the aforesaid means for forming the librous material into loops may comprise a travelling conveyor or any equivalent means, and the loop conveyor or equivalent may be formed with material-engaging projections or other devices.
  • the material may be supplied from one or more cones, cops, bobbins or other mountings on a stationary support, in which event the material can be led to, and placed in engagement with, the devices by travelling or other suitable guide means.
  • This arrangement has the advantage that material can be continuously supplied without the necessity of stop- 'ing with means adapted to draw ping the devices and the fabric-producing mechanism in order to renew the supply.
  • There may be several cones, cops,'bobbins or other mountings and in that event said mountings may supply materialof the. same or different colours.
  • the material-supply means, the devices and thefabric-producing mechanism are all operatively.interconnected to work in timed relationship.
  • All the principal moving parts are preferably arranged, in order that they may work at a high speed, to receive a continuous motion, such as rotary or endless motion, as
  • the feeding devices comprise two helicallv shaped members (in appearance something like slightly open helical springs) which are rotated in unison, the fibrous ma teral ⁇ extending in substantially parallel lengths from member to member and passing along a helical passageway in each thereof,
  • Each feedng device a continuous strip of metal bent or shaped so as to constitute a series ofconvolutions of helical formation and having a portion ,pro-. vided with external teeth whereby the device can be rotated.
  • l is a front'elevation of the mechanism and Fig. 2 is an elevation looking in the direction of the arrow 11 in Fig. 1. i
  • Figs. 3 and 4 respectively are sectional elevat'ons corresponding to Figs. 3 and 4,but drawn to a larger scale.
  • Fig. 5 is a diagram serving to illustrate the 100 'mounted on a stationary frame of anysuit able construction denoted by 10'.
  • the member 12 also has a hook-shaped upper end 12". Itjwill alsobe seen that the members tionsi themselves become reduced in thickness- I r E r I With the two helical members there isv associated an endless chainconvevor disposed immediately in front of the helical members and extending at an inclination between their upper ends. The chain-passes around-two chain wheels 31 and 32journalled'ata corresponding inclination in bearings 33, 34 'sejcured to opposite ends of the frame'lO.
  • chain 30 is driven from the vertical shaft 18 through the intermediary of the following'means,'namely: a chain drive 36 extendin between the shaft 18 and a vertical shaft 2?? an inclined shaft 38 drivenby the shaft 37 through a flexible coupling 39; and V a. chain drive 40 extending between the inclined shaft 38 and the nave 32 of the chain-'- wheel 32.
  • the time relationship between the movement of-the chain and the rotation of the helical members issuch that a projection 35. crosses the top of each member once during each two revolutions thereof.
  • tubules Immediately above the member 11 four tubules are provided .through which are guided four yarns AP, these yarns being of different colours or other characteristics and being supplied from cones, one of which is denoted by B in Fig.2, the yarns passing by I way of any suitable guide arrangement G in the vicinity of the cones and guides 51 secured to. the frame 10.
  • the tubules are carried by little slats, 52 which are pivotally attached at their top ends to avrod 53'supported by brackets 54 which depend I from the frame 10.
  • Eachslat152 has a rounded I portion 55 which.
  • tappets 56 co-operates with one of four tappets 56 projecting radially from a shaft 57 journalled in the brackets 54:," the slats 52 being pulled towards-the shaft 5'7 by springs, one of which, isshown 3.13152.
  • These tappets are equi-spaced angularly around the shaft 57 and they are also spaced apart axially alongthe shaft to such an extent that each tappet can move into register with one portion 55.
  • the aforesaid chain wheel 22 would be driven from arotary shaft -(not"shown) driving or forming a part of the fabric vproducing mechanism in association with which the mechanism according to the present invention would work, and the timing would; be such that the'helical members each perform one revolution for each cycle of operations of the fabric-producing mechanism.
  • this loop can be at once seen y referring to the yarns A A and A each of which is shown pulled into sucha loop in Fi 5.
  • the hook 11 during the rotation of the member 11 moves around and above the yarn A and conveys the-open or left hand end of the loop downwardsalong the helical passageway G.
  • the movement and inclination of the chain conveyor is such that the downward component of said movement has a speed substantially equal to the feeding speed of the helicalmembers, the arrangement being therefore such that the closed end of the loop engaged by the projection 35 moves downwards at the same rate as the open end of the loop engaged by the member 11.
  • the approximate parallelism of the loops is' maintained.
  • the yarns are-all disposed i the axes of that the bearings 13 and 14 offer no obstruction to the downwardly moving yarns.
  • yarns present the appearance of a downwardly moving web composed of a continuous sequence of groups of yarns, .each group containing/two lengths of the yarn A followed by two lengths of the yarn A then two lengths of the yarn A and finally two lengths of the yarn A 'thepassage of the yarns down the helical passageway G in the members 11 and 12, the
  • the yarns can be fed right down from the tubules 50. These tubules are to introduce one or other of the yarns to the pro ect1ons on the conveyor chain for the :purpose of being pulled into loops.
  • the mechanism shown is simple and is adapted to work with only four yarns A to A but if so desired more tubules and yarns o 111g iii-that event increased in dlameter.
