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 attached drawings sufiiciently illus trate the invention and will be referred to in the description'which follows.

Fig. Sillustratesthe provision of alweight car ine auxiliarv traverse bar tvhich lends supfport to-thebrackets carrying the trumpits a nd isparallel .-with the usual traverse,
" middle line of rollers.
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.
Referring in the first place more particu larly to Figs. 1 to l .I there show three lines of drawing rollers marked 1, 2, 3 and all i such rollers may be plain or leather covered and may be self, saddle or dead weighted or otherwise weighted. For very high drafts up to 75 it has been advantageous on the roving frame to have the middle top roller leather covered and dead weighted as indicated at 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.
In 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. Located in the nip of the front line of rollers 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.
In Figs. 5 to 8 a slightly different structure is illustrated. In this case, 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 To the 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.
In Fig. 9 Tshow 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. Also the selvedge guides e are supported by brackets from the auxiliary traverse bar (Z in some such fashion as indicated at Fig. 10. These modified methods of supporting the attachable and detachable trumpets a and selvedge guides e produce a well-balanced arrangement and one which is simple in construction and does not require the use of pendent props as before related. 7
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.
To help in alignment, 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.
Over a wide range of hank, roving or count of yarn 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
' hting on all standard speed frames.
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.
The setting of the guides at and e is of the greatest importance, and the" should be arranged, as shown in the figures, so that the material rests or is held at the bottom of each aperture, this being of particular importance in the case of the front guide as thereby I am enabled to use a slotted front guide which is a considerable help in piecing-up and without risk of making any extra fly, while the elevation also tends to prevent floating fibres.
As regards 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.
Accurate setting and actuation of the traverse bar (such as (Z) is essential. lVith the ordinary gearing, the traverse is too slow for high drafts, consequently I modify the ort-iinary system of driving, using an arrangement on the lines indicated in Figs. 14- and lfi. In this arrangement a double worm m is lined on the middle roller axle 2 and this drives a worm wheel m on the shaft m this shaft m carrying a heart cam m Which acts on a lever on pivoted at m". 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.
I declare that what I claim is 1. The combination with a high drafit speed frame having three pairs of drawing rollers and a traverse bar, of a supporting member carried by said traverse bar and ex tending between the rear and intermediate pairs of rollers, a supporting member carried by the traverse bar and extending between the intermediate and front pairs of rollers, a closed trumpet-shaped condensing guide carried by said first supporting memher and instantly detachable therefrom, and an open-eyed selvedge guide carried by said second supporting member and instantly detachable therefrom.
2. The combination with a high draft speed frame having three pairs of drawing rollers and a traverse bar, of a supporting member carried by said traverse bar and extending between the rear and intermediate pairs of rollers, a supporting member carried by the traverse bar and extending between the intermediate and front pairs of rollers, a closed trumpet-shaped condensing guide carried by said first supporting memher and instantly detachable therefrom, and an open-eyed selvedge guide carried by said second supporting member and instantly detachable therefrom, the operative portions of both of said guides being disposed slightly above the line of contact of the upper and lower rollers of the respective pairs.
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.
4. The combination with a high draft speed frame having three pairs of drawing rollers and a traverse bar, of a bracket secured to said traverse bar, a supporting member pivotally carried by said bracket and extending between the rear and intermediate pairs of rollers, resilient means for opposing swinging movement of the supporting member on its pivot toward the rear rollers and positive means for preventing swinging movement toward the intermediate rollers, a supporting member carried by the bracket and extending between the intermediate and front pairs of rollers, a closed 5 trumpet-shaped condensing guide carried by said pivoted supporting member and instantly detachable therefrom, and an openeyed selvedge guide carried by said second supporting member and instantly detachable therefrom.
In testimony whereof I have signed my name to this specification.
