FILLING-CARRIER OR BOBBIN.

a citizen of the United States, residing at Providence, In the county of Providence and State of llhode Island, have invented certain new and useful improvements in Fi ll ing-Carriers or Bobbins, of which the following is aspecification.

My invention relates to improvements in filling-carriers or bobbins for loom shuttles and the object of my im )rovement is to provide a bobbin that shall c more ctiicient and durable and proof against damage or destruction from hard usage.

The invention is fullv described in the following specification, illustrated by the accompanying drawings, in which Figure 1 is a longitudinal sectional View showing the-method of assembling the two parts of the bobbin: Fig. 2, a similar view showing the method of fastening the two arts together: Fig. 3, a view of the finished bobbin: Figs. 4 and 5, cross sectional views on the line AA of Fig. .2, showing details of construction.

My invention consists essentially of a bol bin B comprising a metal barrel or tube 1) on which is fastened a wooden or liber butt or head 71, The barrel Z) may be either a seam less tu be, or, as shown in Fig. 3, a tube having a close but unjoined seam s. The head it is )referably of wood, or it might be made of lil turned up in the conventional form, with a tapered face fand an annular groove 9 at the lhe facefis shown provided with annular steps 9' or it might be groovml with annular serrations to prevent the yarn from slipping when the first courses of the yarn are wound on the conical surface of the head. The groove 9 is designed to receive the holding device of the shutl e, usually a spring jaw or clip; but it will be understood that the par ticula-r form of head shown and described is not essential to the present invention.

to form a flange Z, which enters and engages the groove, as shown in Figs. 2 and 4. i

In Fig. .5 is shown another method of en gaging the tube with the head, which cons'ists of forming teeth or projections 71;. on the end of the tube and turning these up into the head. In this case it is not necessary to turn a groove in the bore of the head, as the teeth, being sharp, will make indentations for themselves in the wood or fiber.

It is pointed out that the first described method of fastening the tube in the barrel is preferable because the end of the tube does not have to be cut or notched, and further, there will be less tendency to s lit the head when the la tter is made of woot It will be seen that my invention provides for a light, yet strong structure capable of being manufactured at small cost and particularly durable to resist wear and hard usage. It has manifest advantages over the ordinary wooden bobbin for the following reasons: 'lhe ordinary bobbin, being made of wood, is susceptible to atinos )heric conditions and liable to shrink, swell and warp. This often makes it unlit for use, as the bore will shrink to such an extent that .it cannot be placed on the shuttle spindle without. splitting its barrel. Also, when the barrel is Warped it is liable to he s lit from forcing the spindle into it. Again, i re barreLis apt to be splintered or split from hard usage, as the bobbins are often thrown from a distance into boxes or troughs. .[t is also well known that a common practice in the mill is to cut waste yarn oil' the bobbin by drawing a knife along the barrel. 'lhis raetiee, when continued, damages the bob )in by making cuts and splinters on the surface of the barrel. When the barrel is thus damaged or marred the yarn will not deliver from it without catching and breaking so there is more and more waste 0'1 yarn each time the bobbin is used. .111 my new bobbin all of these objections are removed because the barrel, being of metal, cannot split, splinter or chip and its bore remains straight and true and prool against distortion. The improved bobbin will stand the roughest usage and abuse and is practically indestructible.

Having now described the form and purpose of my invention and its particular features of improvement, without limiting my self to the precise construction shown, what I claim is til) Ill)
