Claims.

. i r l This invention relatesto carriers for knitting machines.

Such carriers consist essentially'of a body portionattached at one end to an operative part of a knitting machine with their other ends provided with thread guiding means secured thereto. Such guiding means, usuallyin the form of a thread guiding tube, have a short life due to the wearing away of the metal tube due to the frictional grinding action ofthe thread. Itis therefore necessary to detachthe carrienand remove thethread-guiding tube-and replace it byanother. As such tubes are secured by brazingor welding, such-removal is difficult and time consuming. [The replacement action is equally difficult and time consuming. Also, operators of suchknitting machines, are, as a rule, indisposed to the making of mechanical repairs.

h The object of this invention is to provide a carrier in which the thread guiding tube maybe readily detached and another one may be replaced by anyone and with con enience and speed.

For this purposathe invention consists of a carrier in which a thread guiding tube is detachably secured, whichtube is self-contained with its means of attachment. More particularly, such a'tube consists of a bodyportionof flexible tubing one end of which has secured thereto a thread guiding nozzle and the other end of which body portion has a tubular connection secured to a button member which has a cylindrical portion slightly larger in circumference than that of a receiving hole arranged in the carrier, to obtain body portion of the carrier. The tubular connection extends through the .button member and preferably extends beyond the same in a flared thread inlet portion for the passage of the thread passing along the top of the carrier.

The invention will be more fully described hereinafter, embodiments thereof will be shown in the drawings. and the invention will .befinally pointed out' in the claims.

Fig. 9 is an enlarged longitudinal sectiontaken one line 9- 9 of Fig. 5 of :the self-contained thread'guiding means. showing onlya part of the carrier, and

Fig. 10 is a perspectivefview of another known form of carrier, but having the improvement made part thereof.

Similar characters of referenceindicate corresponding'partsthroughout the various views.

Referring ;to the drawings, one form of known carrier is shown in Fig. Land another form shownin Pig/1O. Each has the improvement of like construction applied thereto.

The body portion H! of the carrier l I, has open-- ings l2 at one end to attach it to a imittinglmachine. The form ofFig. 1 has two ends, 13 and l4, flaring outwardly; andthefformof Fig. 10 has two ends brought together in a pointed end 15.

Each body. portion 310 has an elongated slot It. The thread 20 enters this slot iii, in .the Fig. 1 form from above the body portion. I0, and in the Fig. 10m after thethread 20 has first passed through an additional opening 11, necessary due to the shape of the attaching end of the carrier. The carriers II have grooves l8 for the guidance of the thread. In bothforms, thefront .parts 13 and L4 of the bodyl portions areseparatedi rom each other to enable, a thread guidingmernber circular button member 25, and extends beyond the same in a flared portionf'ifigfqrming preferably, an integral portion of the connectin member 21.

The subcaliber portion 24 has an outer diameter of 5 6 of an inch, and the bore of the tube 22 has an inner diameter of 3 of an inch, in the embodiment shown. Thus, by forcing the subcaliber portion 24 into the bore of the tube 22, a

tight fit and securing connection is obtained. Likewise, one end of the connecting member 2.! has an outer diameter of of an inch, and the forcing of it into the bore of the tube 22, brings about a secure hold.

The button member 25 has a cylindrical portion 28 with a diametrical bore 29, through which the connecting member 21 passes, these parts being held together by a frictional hold by different 7 diameters as described.

The ends 13 and i 4 of the carrier H have two opposed circular cutouts 32, one at each side of a slot 3 0,which separates the parts I 3 and M of the carrier ll, the circular cutouts 32 being not quite semi-circular, but having'acontour concentric with the cylindrical part 28 of the button part 28 has an umbrella? like top 3| which extends circumferentially beyond the cylindrical part. I

The nozzle 23, the flexible tube 22, the connectjing member 21 and the button member 25 are all secured together,-as described, as a self contained group or unit.

The unit is secured to the carrier by inserting the cylindrical part 28 into the circular opening formed by the almost semi-circular cutouts, and by reason of the diversity of the diameters, a

frictional hold is obtained, the extending umbrella flange, abutting against the carrier, limiting the insertion movement of the button member. Thereby, the unit is secured to the carrier. The unit may be removed. by an opposite movement and a new unit-may be readily inserted. The directions ofthese movements are substantially perpendicular to the plane-passingthrough the upper suriace ofv the ends [3 and I4 (Figs. 5 and 1 0). v

The unit has one end of the flexibletube seat itself between the walls forming the slot 30, there being, a frictional hold here, in addition to the hold brought by the button member. The part of the tube with its. nozzle extending beyond the wells of the slot 30 is flexible and permits the I thread emanating from the nozzle to move freely in-any angular direction, so as to cooperate with the needles of the knitting operation.

' I have described several forms of my invention,

.but obviously various changes may be made in i the details disclosed without departing from the spirit of the invention as set out in the following claims.

I claim:

1. In a carrier for knitting machines, the combination of a carrier having means for attachment to a knitting machine, and having a guiding point portion, with an opening, and a thread guiding attachment including a cylindrical button member adapted to seat in the wall-s of said opening, a flexible tube secured at one end to said button member by a connection member, and a t r a uiding nozzle secured to the other end of said flexible tube.
