Definitions

  • the improvements lormingthe subjectn'iat-ter of this invention are concerned with high draft speed frames for drawing, twisting and Winding cotton or textile material, that is, the group of machines following the drawing frame and up to and including the roving frame or it may be even the ring; frame or mule. a
  • the purpose of the slubbing, intermediate, and roving frames is to gradually arrive at the desired fineness and to permit of the requisite drawing by theintroduction ateach frame of acertain amount of twist due to the flye'rs at each stage of thedratting oi? the rovingdelivered by "the drawing rollers.
  • the amount of dratt is limited, because it this ishigh, serious licking occurs. If the draft is too high the material cannot hegot through the rollers at all because the licking is-so considerable.
  • My invention contemplates the automatic consolidation by a mechanical deviceof the passing sliver inconnection With-the dra-w rollers of high draft frames of theclass indicz'ited.
  • This consolidation enables a high draft to be eli'ected without licking although the material has no twist, real or :t'alse,u 'itil alter it is delivered at the front rollers.
  • the device used is in the natureol a small stationary or non-rotary trumpet or a hollow truncated cone and oueoi'such iswapplied for each sliver and is mounted. on a support and lies between the back line of drawing rollers and the middle-line Where there is adequate space tor its support.
  • the sn'ialltrumpets may vary, the sameibeingq-detaehably secured'either to provide spaced brackets car-- ried directly or indirectly "trom'the traverse bar, or the b ackets which support the trumpets may be additionally rmpported by aprovided slidahle or guided traverse haiparallel with the usual traverse, or such small trumpets may be applied to an auX- iliary traverse bar Which in such a case may serve for the mounting of the small trumpets.
  • My invention alsoconcerns an adjunct to the small trumpet or truncated cone device which takes the form of a vselvedge guide having an inwardly open eye or eye of other type and which located between the trout and second line of drawing rollers and Othein'limtures o't"construction will he e plained in detail in the i ollou' iug description.
  • FIG. -1 is'an elevationshowing the general idea, that is, a detachable trumpet shaped device which prevents licking, and a selvedge guide which also prevents licking, each group supported from the traverse FignQshows separated the elements of the detachable trumpet shaped device.
  • Fig. 3 shows separated the elements 0 i' in:- Fclvcdge guide and a bracket.
  • -tl is a diagram showing that the applied devices are set to elevate the tibres above the lines of contact of the rollers and prevent them floating.
  • Fig; '5 is'a view similar to Fig. l but indicating: slight modifications. r i
  • Fig. '7 is a front elevation of the detachahle trumpet and its supporting bracket
  • Fig.8 is a view of the sclvedgre guide, its bracket and a iiront support all seen in Fig. i r
  • Figs. 12 and 13 are general arrangement views which also indicate how the sliver cans may be creeled for close pitching.
  • Figs. let and 15 indicate how the speed of the traverse bar or part can be quickened as is found. desirable.
  • rollers marked 1, 2, 3 and all i may be plain or leather covered and may be self, saddle or dead weighted or otherwise weighted.
  • Fig. 11 Roller gearing arrange ments using a system of double carriers are required to secure very high drafts and this is indicated at Figs. 12 and 13.
  • Fig. 1 the small trumpet or hollow truncated cone is marked a, and it is shown separately at Fig. 2. It has a handle a and lower bevelled or grooved sides a to fit the bevelled prongs Z) of the lever element Z) which is fulcrumed at b to the base element Z) of the complete bracket.
  • This complete bracket Z) is fixed to a small cranked bracket applied to the traverse bar d whereby each trumpet a partakes of the motion of the traverse bar.
  • the lever element 6 is held by plate spring 5 which, acting on the element 6 presses the trumpet a closely into the nip of the middle line of rollers 2.
  • the selvedge guide separately shown in Fig. 3. This is illustrated as an open-eyed detachable guide 0 with bevelled sides 6 litting a bevelled edge slot in the bracket 6' which is secured to the bracket 6, as Fig. 1 shows.
  • the attachable and detachable trumpet a and the selvedge guide 6 are so set that the lower operative contact face elevates the fibres, thus producing sufficient drag on fibres which are not gripped by either nip to prevent them being floated forward, until the ideal time for drafting. and this is indicated in diagrammatic form in Fig. 4. This enables me to make use of normal roll or stands.
  • Figs. 5 to 8 a slightly different structure is illustrated.
  • the detachable trumpet a (see also Fig. 7) is carried in a. right-angle bracket 5* which is bolted to a bracket 0 secured to a traverse bar cl and the fineness the selvedge guide 6 (see also Fig. 8) is detachably carried in a bracket 6
  • a crutch or prop is fixed, and its rounded lower extremity slides on the roller beam (see Fig. 5) a number of such spaced crutches or props f being used.
  • Fig. 9 T shows an auxiliary traverse bar (Z* to which the bracket elements 6* can be attached.
  • This auxiliary guide is parallel with the traverse bar (Z and slides on the upper face of the roller stand. It serves as a guide and obviates the use of pendent props.
  • the Fig. 9 indicates a slight modification in that the auxiliary guide bar (Z is guided in provided. brackets (Z and these brackets may be adjustable.
  • a modified way of supporting the attachable and detachable trumpet a and the selvedge guide 6 is indicated at Fig. 10 where an auxiliary traverse bar (Z is located and guided between the back and middle line of rollers and this auxiliary traverse bar is furnished with upwardly projecting arms a* bevelled or grooved on the inner opposing faces of the upright arms to receive the spaced attachable and detachable trun'ipets a.
  • the auxiliary traverse bar (Z is interconnected with the main traverse bar (Z by brackets.
  • the selvedge guides e are supported by brackets from the auxiliary traverse bar (Z in some such fashion as indicated at Fig. 10.
  • the positioning of the attachable and detachable trumpets and the selvedge guides is very important. They should be set-up as close to the middle and front roller nips as is possible and, where exceptional close fitting is needed the arrangement according to Figs. 1 to 3 very good, because the spring 6, whilst pressing the trumpet close to tho nipyet allows the element 7, to be pushed back to remove the trumpet without interference from the top middle roller.
  • the selvedge guide 0 should be so constructed and held that it fits its vertical support as truly as does the trumpet a whilst at the same time it is removable. This is important because the al terations of size of the orifice or passage way varies slightly according to the fineness of the bank, roving or yarn being spun.
  • the trumpet guide a is univcrsal, the orifice being say about diametcr at the point nearest the roller nip, whilst the selvedge guide 6 may be varied 91; ofan inch or more or less according to or coarseness of the bank. Guides so set are effective in securing high ill) drafts with all cottons using the existing types of rollers, rollerstan'ds,clearers, and
  • the trumpet guided is essentially acondensing guide which smooths out all fluiit ness of the sliver and condenses the cotton whichis all that isrequired before feeding it to the middle roller nip.
  • the selvedge guide 0 is essentially a selvcdge guide rather than a condensing device. The two guides a and 0 enable very high drafts to be secured without licking.
  • creeling of the sliver I use the arrangement indicated by Figs. 12 and 13, using small cans such as g, g. A full can of say 8 lbs. sliver will, using high drafts and at normal liver speed, last a considerable time and therefore owing to possible deterioration through the sliver standing too long I prefer to use shallow cans g, 9 instead of standard cans.
  • the shallow cans g are fitted into the ordinary largecans 9 which stand on the floor whilst the small cans g rest on a table or ledge h, the top cans being of such a height and so located as to be convenient for the operative. In this way it is possible to so closely pitch the cans as to get suflicient ends to feed all the flyers in the frame.
  • the slivers from thebottom cans g pass over brass rollers '5 and are fed through the usual U shaped guide into the nip of the back line of rollers 1.
  • the slivers (not shown) from. the top cans g pass over similar brass rollers 11*, then vertically down and underneath a third line of brass rollers i and are likewise fed to the back roller nip.
  • the sets of three brass rollers 71, i i are positvely driven by an endless chain is from a sprocket wheel on the back line of rollers 1. These rollers may be grooved or corrugated to preventadjacent slivers running together.
  • a connection is made by a linlr m tothe traverse bar" (J whereby motion imparted to the lever m by the heartcmn m is conveyed to the traverse bar (Z; Lever m? is slotted at on so. that the motion conveyed fronnthe heart camm can be regulated
  • the lever wa tarcrumed at m is the opposing lever tom the two being interconnected by a spring m
  • Such an arrangement gives a short and more rapid traverse to the bar (Z.
  • the coirrbination with a high draft speed frame having three pairs of drawing rollers and a traverse bar, of a pair of interconnected supporting members carried by said bar, one extending between the rear and intermediate pairs of rollers and carrying a closed trumpet-shaped guide, and the other extending between the intermediate and front pairs of rollers and carrying an openeyed selvedge guide, the supporting member for the closed trumpet guide being resiliently maintained in operative position.
