inotherA objectief-the invention is to provide a clutchv whichwill be extremely simple and require a minimum of operations for making or assembling the same on the blade.
Another object of this invention is to provide a clutch which will be so arranged that the bobbin will be accurately lined up with the blade when positioned thereon, that the bobbin may rotate at high speeds Withoutany eccentricity, wobble or play which causes wear upon the spindle.
n Another object of the invention is toprovide a clutch which will vary to the size of the various bobbins which may be utilized regardless of their condition of swelling or drying out due to variation in moisture conditions. V
With these and other objects in View, `the invention consists of certain novel features of construction, as will be more fully described and particularly pointed outin theappended claims.
In the accompanying drawing:
Fig. l is a sectional view showing a blade with a bobbin mounted thereon and my improved .clutch in position;
Fig. 2 is a sectional View on a larger scale of a iragmental portion of the whorl, I blade, and clutch; Y 1
Fig. 3 is a view similar to Fig. 2 illustrating a n blade which is Fig. 4 is a sectional View on line 4 4 of Fig. 2; Fig. 5 is a perspective viewof o-ne of the nesting Fig. o' is a perspective view of a modified form I of clutch member in that the split is arranged helically instead of longitudinally of the clutch formed nested tubular members tapered at their ens. the` other. `andino dirt` can enter within due to the `fact that the split portions arenot inreg-` istry, Vwherebylthe clutch will function for along period of time `Without ruining` With. reference. to the'drawing, I 0 designates ablade upon whichisrnounted a `whorl `II .having a driving belt receiving ..porton..l2.

I. providearecess I4 while a `co11ar-l5 extends .upwardly Vloeyi'm" :1 the top I6 of thewhorl to. snugly embrace. the spindle bladeIII.f u A I p The.. clutch .consists fof a` .pair .of .nested`v tubes one of which isV shown in perspective inFig.5 and designated generally II. There is a cylin` drical portion IB of each tube with a frustoconical upper portion I9 formed by drawing the tube inwardly. The tube is split longitudinally throughout its length as at 20. Another. similar tube designated 2| is nested Within this tube II and contacts with it. However, the split or slot 22 thereof, similar to the split or slot 2U, is out of registry as shown in Fig. 4. As these tubes contact substantially throughout their outer and inner surfaces, one supports the other and further no dirt can enter into the hollow portion within the nesting` tube. In order that these tubes may maintain this relative position, a pin v shown clearly in Figs. 1 and 3. When the bobbin` is removed and the clutch is in relaxed position as shown in Fig. 2 the tubular members expand so as to be substantially in contact withthe' outer periphery of the surface of the groove I4 as well as in contact with the flange 25 of the ferrule 24.
As the bore 29 of the bobbin 26 is positioned the tapered portion of the clutch guides the bore and the clutch is compressed so that the inner tubular member 2l will-engage` the collar I5 and truly align this lower end of the bobbin with the blade at. this location while at theupperend of the bobbin the bore 21 will engage the blade I0 and truly align this end of the bobbin with the bladekThus, by this relationship whereby the slit 33 as shown in Fig 6 at l1', but the sleeves will be otherwise the same both as to the outer sleeve and the inner sleeve which will nest therein.
I claim:
1. In a spindle, a blade, a bobbin clutch comprising a pair of nested resilient split tubes surrounding said blade and .out of contact therewith for the entire length of said tubes, said tubes snugly fitting each other and with their 'split edges out of registry whereby to limit the entry of foreign matter within said tubes.
2. In a spindle, a blade, a bobbin clutch comprising a pair of nested resilient split tubes, sur- .rounding said blade and out of contact therewith for the entire length of said tubes, said tubes with their split edges extending helically and out of registry whereby to limit the entry of foreign matter within said tubes.
3. In a spindle, a blade, a bobbin clutch comprising a pair of nested resilient split tubes surrounding said blade and out of contact therewith for the entire length of said tubes, said tubes with their split edges out of registry whereby to limit the entry of foreign matter within said tubes, said tubes. having frusto conical upper portions.
4. In a spindle, a blade, a bobbin clutch comprising a pair of nested resilient split tubes surrounding said blade and out of` contact therewith for the entire length of said tubes, said tubes with their split edges out of registry whereby to limit the entry of foreign matter within said tubes, and a ferrule about the upper edges of said tubes to limit their expansion.
5. In a spindle, a, blade, a bobbin clutch comprising a pair of nested resilient split tubes surrounding said blade and out of contact therewith for the entire length of said tubes, said ,tubes with their split edges out of registry whereby to limit the entry of foreign matter within said tubes, said tubes having frusto conical upper portions, and a ferrule about the upper edges of said tubes to limit their expansion.
6. In a spindle, a blade, a bobbin clutch comprising a pair of nested resilient split tubes sur-.
rounding said blade and out of contact therewith for the entire length of said tubes, said tubes with their split edges out of registry whereby to limit the entry of foreign matter Within said tubes, and means to prevent vrelative rotation of the clutch and blade.
7.'1 In a spindle, a blade, a whorl thereon having a collar at its upper end and a recess about the collar, a bobbin clutch comprising a pair of nested resilient split tubes surrounding said blade and out of contact therewith for the entire length of said tubes, said tubes extending into said recess and surrounding said collar and normally free thereof and adapted to be contracted by the bobbin to cause the inner tube to engage said collar.
