This invention" relates to carriers or spindles for'braiding machines, and the like, such as plaiting machines The object of the invention is an improved constructional form of carrier or spindle suitable for work at higher speeds than has hitherto been possible.

The invention is illustrated 1n the accoinpanying drawings in which r Fig. 1 is a side elevation of one form of carrier made in accordance with the invention. v V

Fig. 2 is a plan of Fig. 1.

Fig. 3 is a rear elevation of Fig. 1.;

Fig. 4 is a sectional plan on line 4 4 Fig. 1.

Figs. 5 and 6 aredetail views of a modified construction of eyelet for the upper end of the back and other parts.

As illustrated, the base a of the carrier is a casting, the lower part of which is formed with an oval sliding surface 6, a depending guide web 0, a retaining flange d and a driving peg 6. At the leading end of the base is an upstanding column f in the top of which is fixed an upright steel rod g formingthe spindle for the bobbin holder. In the base ofv the column f is a through slot in which is in at the time'of casting the base, is a flat steel back Z, the edges or narrower sides of which are rounded. In the steel backand at a point upwards from its base about twothirds of its length is a split eyelet Z cut intothe back for quick yarn threading, the cut or split of the eyelet being inclined downwardly towards the hole, the edges of which 5 arebevelled; Below the eyelet is a hole m which receives the end of a spring wire collar m wound to fit'closely on the back and pro-.

, viding a quickly fitted stop. On the back and below such stop are arranged in ordera stop plate or collar n of 'D shape, a light wire coil nut cut-(see Figs. 5 and 6).

spring 0, round or flat to conform with the shape of the back Z,-and a sliding-weight p, the latter'having the usual hook p for the yarn g, 'ancl-wings p I i At the upper end of the back -Z is a pigtail eyelet 1', made entirely of wire, the eyelet end 7* projecting behind the back, the other part of-the wire being wound to fit closely to the back Z with the extreme end r bent inwardly to fit into ahole in the back and thereby be positioned. On theback- Z isa" light coil spring 8, round, oval or rectangular as in the case of the yarntensioning spring 0, and forming a return spring for the catch it through a catch wiret, which lies alongside the back, the upper end being bent to fit slidably on the back and to engage "the lower end of the light spring 8 and the other end being hooked round the stud 7' of the catch counterweight. Intermediate of its lengththe wire t is doubled on. itself to'form a laterally projecting loop 25 'adaptedito be engaged by one of the wings p of the tensioning weight 713.

Oval springs, such as s shown'inFigs. 5

and 6, may be used instead of round springs. The bobbin holder itself is formed with a long spindle constructed in known manner to hold the bobbin and is cast with a light cir= cular base u having downwardly projecting webs '0 to be'engaged by the catch 719, the hub of the base normally bearing on the top of the column f already described.

The wire pig-tail eyelet at the top of the back may be replaced by a steel eyelet w threaded and screwed into the top of the steel rectangular back and locked in position by a f The operation of the carrieras one of 'a known type and its movements in the braiding' machine will be well known and the manner in which the tensioning weight p is loop 25. of the catch wire tfrequently, to -release the bobbin'as more yarn is required and always again releasing the catch h so that the bobbin is held and so that the re- 'quired tension may be maintained. Theimproved carrier has the. advantage that-the difliculty with these carriers.

it is less fragile and-by casting it in'witli the base part the advantage of the rigidity of the ovalsection'back is retain-ed'without the disadvantage which would result from the larger diameter of rod that would be required if round and having the same lateral rigidity,and also the cost offiXing the parts together is very small as wellas ensuring absolute rigidity. Further, there are few parts to work loose which'is the main The general construction'anid arrangement of the parts 4. A carrier according to claim 2, characterized in that the said further stop at the upper end of the guide is made of wire coiled to fit closely on the guide and having one end turned in to engage a hole in the guide, and the other end projecting and twisted to form a pig-tail thread eyelet, as set forth.

is of importance in so far as security with ease and simplicity of their attachment or replacement 18 obtained, but the inventionis not limited to the particular details of the example above described as will be apparent from the. description itself.

Vhat I claim is r 1. A bobbin carrier for-braiding machines and the like-having a. vertical guide, a thread eyelet in the guide opposite the-bobbin, a

catch releasemember slidably mountedatits upper endon the guide above the said" thread eyelet, .anda thread tension. weight slidably mounted on the guide and adapted to engage the said catch release'member, characterized by a stop on the guide belowthe said thread eyelet, a spring'on the guide between the said stop and the thread tension weight, and a projection on the catch release-member intermediate'of its length, to beengaged by the said. weight, as set forth.

2. A carrier for braiding machines and the like having a vertical guide, a thread eyelet in the guide opposite thebobbin, a catch release member slidably mounted. at its upper end on the guide above the said thread eyelet, and a thread tension weight slidably mounted on the guide and adapted to engage the said catch releasemember, characterized V by a stop on the guide below the said thread eyelet, a spring onthe' guide-between the said stop and the thread tension weight, a projection on the catch release member intermediate of its length to be engaged by the said weight, a further stop at the upper end of the guide, and a further spring on the guide betwcensaid further stop and the upper end of the catch release member, as set'forth.

0. A carrier according to claim 2, further characterized in that the said further stop at the upper: end of the guide also constitutes a thread eyelet, as set forth.
