The creel or table may be horizontal, inclined or" vertical.

Between the creel and thesetting frame isiixed` anopen comb having the same numberof openings as there are units inarow of design,v and mounted in a convenient position isa diagram of the design, this diagram beingv prepared on squaredpaper and thesduares,being1 coloured to correspond withthe design.

Bins, shelvesy or other suitable receptacles. are provided adjacent the creel or table containing bobbins or cheeses woundlwith yarn `of the" colours required, and the operators proedwbyiirst y consulting the design diagramthen selecting "one or more bobbins for the first one or more, units in thefirst rowof the design and placing then; on,v

The object "of the Vpresent Ainvention isl tovreduce the time occupied'andfto eliminate the` fatigue produced by rewinding operations..` According to the present inife ntior'iy we lprovide rewinding gear comprising afrewinder unit including a 1lcxpdy having a power driven rotary drivi ing member which 'can` be made to `engage and drive anyI onefbpbbin oryarnwfcarrier to effect rewindingl As appliedgto spool `setting theA rewinding unit may be flexiblyv and resiliently suspended' above a creel so that it can be brought into lposition to l act on" any `of the bobbinsor yarn carriers thereorn` lWe may for instance providefone or more sup-Q' porting rails above the creeluponwhieh or upond each ofwhich a movable carriage is provided,` upon which is suspended a rewinder unit. Each rewinderhunit-may comprisea body containingsa power-unit andY a` 'driving shaft,` upon which is mounted a rotary driving member adapted to be moved into drivingengagement with any ofthe `bobbins or `yarn carriers.n

Each rewinder 4unit may be providediwith means for centring the unit in`` relationto `the bobbin or yarn carrier-and such means may incorporate a hollowlmemberlhaving a tapering mouthV for the purpose or-rapidly engagingoverthe ends `or thelpegssup'porting the bobbins or yarn carri-er on theLcreel-.i

Theyarn carriers 'may 'beinA the form of bobf bins,` orcheesea` which-latter consist of yarn usuthe lattermay beprovidedwith a metal flange or plate upon which theyarn carrier rests.` The flangeor .plate may-be adaptedr to revolve freely either with Vtheupeg Lor separately from the peg which `may bea xture.` When theyarn `carrier l projectsiabovefzthe, topofrthew peg. amodied! form of driving unit may be used which may consist ofan inverted cone which can be made to engage with the interior'of thev upper end of the cardboard or other tube in the cheese, or in a suitable recess in the end of a bobbin or other yarn carrier. i Y

Referring to the drawings:

Figure 1 is a perspective view showing the creel or table upon which a large number of yarn carriers are supported for rrotation and also showing a pair of rewinder units and the means by which they are supported.

Figure 2 is a sectional view showing a portion of the creel and two of the bobbins.

Figure 3 is a sectional view showing a portion of the creel upon which are mounted a pair of cheeses.

Figure 4 is a view in side elevation showing one of the rewinder units and the means by which it is suspended.

Figure 5 is a sectional view showing the driving and centring means of the rewinder unit. Y

Figure 6 is a sectional view showing an alternative form of driving member employed for rewinding.

In the construction shown in Figures .1, 2, 4 and 5 the table I0 is provided with a large number of upwardly projecting spaced pegs I I upon each of which is mounted a bobbin I2 carrying the yarn.

The spool is shown at I3 and the comb ,through which the yarns are taken is shown at I4. Be-

tween the rows of bobbins, bars I5`are provided to keep the loose ends of yarn above the bottom ends of the bobbins,

The creel is provided with two upwardly projecting posts IB carrying a rectangular frame Il and each of the side members of the frame I1 is .Y 30 within which are two ball bearings 3I which are spaced apart by a 'distance tube 32 and mounted within these bearings is -a centralising member 33, this centralising member having a tapering mouth 34 so that it can readily be engaged over the upper end of any the pegs Il.

` The sleeve 30 at its lower part is shouldered as shown at 35 and tting against this shoulder is aV rubber tube 36 which constitutes the driving member. The lower end of the rubber tube extends below the centring member 34 and the edge 31 of the lower end of the rubber tube may be beaded and is adapted to engage the top of the bobbin and to drive it, there being suicient friction between the rubber member and the material of the bobbin to effect a driving connection.

Referring to Figure 3 the pegs for supporting v l the yarn carriers are shown at 38 and in this provided with a T section rail I 8 having stops y at its ends. Each of `the rails is provided with a carriage I9v having rollers 20 and suspended from this carriage bymeans of a coiled spring 2I is the rewinder unit shown generally at 22. The rewinder unit is provided with a link A23, by which it is suspended from the spring 2 I. A Other forms of exible and elastic members may be v,

used for supporting the rewinder units..

The body of each rewinder unit contains a power unit which may take the form of a small electric motor or of a small motor adapted to be driven by compressed air or water power or the driving shaft 24 of the power-unit may beadapted f to be drivenfby a exible shaft driven by a suitable motor (not shown).

If the body of the rewinder unit contains a power unit, the power unit is adapted to be switched on or placed in operation by a lever 25 pivoted at 26 to lugs 21 on the body. WThe lever 25 may be acted upon by a spring so that normally the power is switched off or interrupted. In practice, however, the body of the rewinder 22 is grasped bythe operator who at the same time grips the lever 25 and moves it towards the side of the body of the rewinder 22, thus switching on the power and driving the driving shaft 24'.

In the construction illustrated the rewinder unit is driven by a small electric motor contained in the body of the unit and the current is brought to this electricmotor by the cable 28.

In the constructionshown there are two rewinder units, one suspended above 'each 'side of the creel and the two cables 28 may be takenv upwardly to'a central bar 29 on the frame I1 from whence they are taken to a source of electric Supply.

construction the yarn carriers are formed as cheeses, each having a central tube` 39 which projects through ythe end of the winding, the tube 39 usually being made of cardboard.

When cheeses are used the short pegs 38 are provided with metal plates or flanges 40 which if desired may be mounted so that they are free torotate either with the pegs or separately from the pegs which may be xed.

In carrying out the invention it is necessary to identify each bobbin of yarn carrier and for this purpose the upper ends of the pegs` II are numbered. When cheeses are used, however, the supporting pegs may be shorter and may not project above the upper ends of the` cheeses. To

provide the identification of each yarn carrier.

a numbered peg 43 may therefore be mounted on the creel adjacent each of the pegs*` 3,8, or alternatively the number or identifying particulars may be` marked on the surface of the creel adjacent each yarn carrier.

The driving unit shown in Figure 5 may not be suitable for winding cheeses and may be replaced by the driving unit shown in Figure `6. In Figure 6 the shaft 24 is provided with a head 44 to which is clamped by a nut 45 an inverted conical member 46 which may be made of rubber or any other"suitable material and is adapted to engage within the upper end of the tube 39.

In operation, after a spool has been wound,`

the operators, usually one at each side of the creel. bring the rewinding unitsl into action successively upon those bobbins or yarn carriers which are to be changed. Upon being released each rewinder unit automatically stops and returnsto a position above the tops of the bobbins or yarn carriers. They are easily moved along the creel and also across the creel and they can be brought downwardly to engage any of the bobbins or yarn carriers by the exercise of a little downward pressure which expands the spring 2 I.

The following are the main advantages ob-v tained by the use of the present invention:

(l) Rewinding done by power driven units saves operators time.

(2) It eliminates the fatigue of manual rewinding.

(3) When bobbins orother yarn carriers are rewound by hand the loose end of the yarn tends to cling to the other yarn on the bobbin or yarn carrier and is often dicult to find, but the speed of rewinding by power causes the loose end to stand out from the bobbin or yarn carrier so that when next that bobbin or yarnY carrier is required, the end is quickly and easily grasped by the operator.

What we claim then is:

1. A rewinder for rotary yarn carriers comprising a body, a power driven driving shaft in the body and protruding therefrom, a driving member consisting of a sleeve mounted on the driving shaft and having a tube of soft elastic material, the edge of which is disposed below the end of the sleeve and is adapted to engage an end of the yarn carrier.
