T all whom. t may concern:

Be it known that we, EDWARD ADELL, of

.Orange in' county of Franklim vState ofl Massachusetts, and CARL A. BniNK, of Uran'- ston, in the county of Providence, Stateof Rhode Island, citizens of the United States, have invented certain new and useful lin-l provements in Cop or Bobbin Holders, of

r which the following is aspeciication.

vide a bobbin-holder which may be moreand conveniently applied and on which itA will be more: securely held to control `its rot-ation in delivering the yarn or `thread therefrom. v-

Another object of the-invention'is to proreadily placed onand removed from the spindles of the hraider-carrierS, whereby to'- facilitate the application of thebobbins 'to the holder and the-doi'ling of the empty coptubes therefrom.

It isv to beiinderstood, however, that'the present 'improvements are also 'adaptedto be applied to the spindles ,or mandrels-'of other textile apparatus,` such for instance as winding machines. t is the usual practice to control the delivery of the yarn from the bobbins on thebraidercarriers by means of a pawl-mechanism which operates to pei'- mit an intermittent rotation of the bobbinholder under the pull on the yarn. For this A' purpose they bobbin-holder isgenerally provided with a ratchet-disk or head with which i .A Specification of Letters Patent. 1PM-@umd July ,25, 19220 bfobbinlh'older comprises in general va tubuf --lar'sleeve' or mandrel 2 adapted' for insertion in the 'bore ofthe tube on which the cop orv bobhin is wound, and a ratchet-disk orh'ead 3 mounted on the endfof the sleeve. .Als a :novelv feature of the 4 present improvement l toadaptthe bobbin-holder to rotate freely on thespindle of the braider-carrier. The above named essential'eleinents of thedeviee comprising ,the outer 'sleeve 2, the ratchethead 3 and the inner Sleeve or bushing .4 are preferably constructed from sheet-metal and united by an ingenious method of .construction, whereby to provide a particularly staunch reinforced structure capable of resisting hard usage when the bobbin-holders are dropped or tossed about during their handling. A i

Referring to Figs. 5 to 9 inclusive, for convenience of description the ratchet-disk or head 3 may be considered the main element or base of the device since it serves as a foundation for the other parts which are attached thereto. The head\3 is preferably constructed from a circular blank B, see Fig. 5, which is cupped out, as illust ated in Fig. 6, to form a. fla-ring rim or fiange 5 surrounding its periphery. At the center of the head 3 is a circular opening 7 within which the inner tube 4 is held7 and at the sides thereof are rectangular slots 8 adapted to receive suitable end-lugs 9 on the outer sleeve 2 which are riveted therethrough to secure the parts together. in the manner as hereinafter more fully described. The blank B is also punched or perforated with a series of circular holes 10 arranged concenti'ically of its axis and adapted fora purpose as later ex plained.

To form'the ratchet teeth 11 on the head or disk. 3 the rim 5 of the blank B is slit through at intervals and cut away from the main portion of thel disk to provide ears 12 which are bent or folded around into substantially horseshoe shape, as sho-wn in 7. As here illustrated. the ears 12 extend inwardly substantially radial withthe'axis of the disk and their ends are notched o-r cut away at the top to form lugs 13 of less depth than the main portion of the ears, seelFig. 8. At the next operation the ears 12 are bent or forced toward each other and folded into substantially parallel overlapping relation, asvshown in Fig. 9. It will be note-d thatl when the ears 12 are bent into this relation their'end lugs 13 will be brought into register with the holes 10 in the disk 3. At thenext operation the metal in the lugs 13 is crushed or extruded down through the holes 10, as shown in Figs. 2 and 10, thus forming a bond or tie between the extrem-v construction the ears 12 are firmly anchored to the disk at their inner ends, while their outer folded portions are united to the periphery of the disk 'at the points where they join therewith@ ln this improved structure the double ears 12 form the reinforced radial teeth 11 projecting from the face of the disk 3 to adapt them to be engaged by the pawl or detent which controls the rotation of the bobbin-holder in the manner and for the purpose as well known in the art.

Referring now to Figs. 1, 2 and 3, the

outer sleeve or mandrel 2 on which the cop .outwardly from the cylindrical end portions 17 of the sleeve 2, see Fig. 2, and extend sub- 75 stantially parallel tothe axis of the holder throughout substantially their full length. lVhen the paper or fibre cop-tube C is slipped on' over the sleeve or mandrel 2 the springmembers 16 are compressed slightly and at 8O 'the same time their sharp edges 18, see Fig.

3, will bite into the .bore of the tube C whereby to firmly grip the latter to secure the bobbin to the holder.

YIt has before been noted that one end of the sleeve 2 is provided with projecting lugs 9- and, as shown in Figs. 2 and 10, these are inserted through the slots 8 in the disk 8 and headed over to rivet the tube to the disk.

The outer sleeve or mandrel 2 is further held to the disk 3 by means of the inner tube or bushing 4 which serves as a reinforcing element 'in the manner as next explained. Referring to Figs. 2 and 4, the bushing 4may. be constructed from seamless 95 drawn tubing or may be rolled from at stock as herein shown. The main portion of the tube 4 is of appropriate size to adapt it to fit freely onto the spindle of the braider-carrier, but at its lower end the tube is flared or belled outwardly to provide an enlarged mouth portion 19. At its upper end the smaller main portion of the tube is inserted through the axial hole 7 in the disk 3 while its lower enlarged end' fits closely within the end of the outer sleeve 2. After the tube 4 has been applied to position in this manner its ends are swaged or headed over at 20 whereby to secure it in place; and in this way the tube 4 serves as atie and re- 110 inforcing element for the outer sleeve 2 and materially strengthens and stiffens the whole structure.

Midway the ends of the inner tube 4 is a stop-limit or rest 21 for the spring-members 115 16. The stop or. rest 21 consists simply of an annular abutment or raised "ring against which the spring-members 16 "bear when they lare compressed toward the axis of the holder'. The abutment or annulus 21 is pref- 120 erably formed by swaging out the metal of the inner tube 4 in a convex ring, as shown in Fig. 2, or if preferred a wire ring 22 may be applied to the periphery of the tube 4 as illustrated in Fig. 4. l The purpose of this 125 stop-ring or rest 21 is to limit the contraction of the spring-members 16 to prevent them'from being bent inwardly to such an extent that they will fail to react to the outermost limits. It is well known that spring- 130 metal will flex and react to a certain extent,

' but beyond this limit it becomes set and loses more readily applied thereto.

its resilience, so that the stop-ring 21 is provided to prevent the spring-members from being contracted beyond the safe limit. The purpose of the enlarged bell or mouth ,19 at the bottom of the sleeve t is to provide for an easier entrance for the end of the carrier-spindle S, Which is shown by dotted lines in F ig. 2 to illustra-te the manner in which the carrier is slid over it. By this provision the application of the bobbincai'rier to the spindle is rendered much easier and more convenient, tending to a saving in time and elfort on the part of the operator. be readily slipped onto and off from the spindles so that the-oops or bobbins may be This saves the operator from reaching in over the machine to a'pply the bobbin to the holder when the latterjis less accessible than when held in the hand;- This improvement is of particularly advantage in facilitating the.

doliing of the'empty cop-tubes from the holders since they frequently stick'and require considerable force to pull them 0E. Moreover, this method of applying the bobbins and doiiing the tubes eliminates the danger of bending the spindles, which is to be avoided so that the holders AWill turn freely and run true thereon.

It will be observed that our improvement provides a bobbin-holder of particularly light yet staunch and rigid construction, ca-

vpable of resisting rough handlingand hard usage and proof against Wear or deterioration. The end-liead or ratchet-disk on the holder is much lighter in Weight than the usual cast-iron ratchet, yet possesses the necessary strength and stiffness in its reinforced teeth.I The outer sleeve of the holder provides a particularly eiiicient gripping-means. for securing the' -bobbin in place on the holder and the resiliency of its spring-members is preserved-from 'deterioration by the stop-ring orv abutment which prevents them from being crushed outv of shape. The inner tube forms a straight smooth bearing for the holder on its spindle, and inaddition serves as a tie or strut to The several parts of the device are Secured together by a novel method of constructionvwhich renders. them mutually reinforced and strengthened, While the complete device isdesigned for economical manufacture to cheapen its cost.

Various modifications may be made in the form and arrangement of the parts of the device Without departing from the spirit or scope of the invention, therefore Without I limiting ourselves to the exact embodiment herein shown and described, We claim:
