BRAIDER CARRIER Filed Aug. 5, -1937 VfL 0 INI/ENTOR.

ATTORNEYS.

Patented Jan. 24, 1939 UNITED STATE-S PATENT OFFICE 16 Claims.

This invention relates to a carrier for a braiding machine; and has for one of its objects the provision of a braider carrier which will receive a yarn package of a larger diameter than carriers which are in customary use at this time, whereby the replenishing of the package will be less frequent.

Another object of the invention is the provision of a braider carrier which will carry a stop for throwing off the starting handle of the braiding machine should any of the yarn fail, which stop is entirely independent of the yarn take-up of the carrier.

Another object of the invention is the division of the take-up and stop with the stop arranged to remain below the package and thus permit use of a larger package than would otherwise be the case on a carrier.

Another object of the invention isv the provision of a long spring for actuating the yarn take-up and a cover for concealing the spring so that it will not be subject to dirt or lint and will present a device of a more finished appearance.

Another object of the invention is the location of the yarn take-up above the stop so that should the yarn fail and the take-up drop the momentum gathered by the take-up will serve to actuate the stop and move it to stopping position.

With these andother objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is an elevation of the braider carrier equipped with my new mechanism;

Fig. 2 is a perspective view of a fragmental portion of the carrier showing certain of the operating mechanism;

Fig. 4 is a perspective View of the guide standard;

Fig. 6 is a sectional View on line 6-6 of Fig. 3.

In the use of braider carriers it is customary that the stopping mechanism be lifted with the yarn and used as a part of the yarn take-up for vertical movement along the guide Standard. It has been proposed that the stop mechanism be not so lifted by the yarn and certain arrangements have been made which attempt to effect this purpose, but these are not in practical use 3 and aremor'e or less theoretical proposals, but not any of these cause the take-up mechanism to be completely independent and separate from the stop and so located above the stop that it may drop into Contact therewith, such as 1 propose, with some means to lift the stop when relieved of the weight or pressure of the take-up means thereon; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, I0 designates the base of the braider carrier with its flanges II and I2 on either side of the race-Way guide slot in the top plate of the machine. A boss I4 extends upwardly from this base and a package spindle I5 extends from the boss to support the bobbin having a base plate i6 with downwardly extending teeth II upon which the cop of the yarn package i8 is mounted'. A latch I9 is pivotedas' at 20 on this boss I4 so as to move into a position to block rotation of the yarn package bobbin by being positioned to engage the teeth I 'I thereof, the package being released upon rock-l ing of the latch in one direction and arrested by contacting the latch when rocked about its pivot in the other direction.

A tubular guide standard 2I is supported in a socket 22V in a projection 22 on the'base I0 and is slotted as at 23 throughout a portion of its length.

A stop of a shape which may best be seen in Fig. 2 is designated 25 and slidably engages the guide post 2i by reason of an opening 25 in the stop which receives the guide post and also an arm 21 whichV is folded back upon itself and provided with a guide opening 28 also receiving the guide post so that the stop is slidable vertically of the post and guided thereby. A pair of ngers 29 extend inwardly from the stop and receive the pin 3i) having a head 3| to limit the upward movement of the stop, this pin being threaded as at 32 into the base I 0 and surrounded by a spring 33' which engages the stop, and although relatively light is of suicient strength to lift the stop when no weight rests upon it.

The yarn take-up consists of a slide member 35 having a pair of spaced ears 36 and 31 with openings to slidably receive the guide post and also provided with a hook @E beneathvwhich the yarn extends so as to lift this tension member 35 upwardly or the tension member will drop to take up any slack in the yarn. A long spring 39 is housed within the standard 2l and rests against a set screw 4I! threaded into the upper end of this tubular guide. An L-shaped member 4I extends inwardly through the slot 23 in the guide and is provided with a pin 42 extending into the axis of the spring 39 to receive and guide the same while the spring forces this member 4l downwardly, this member being attached to the take-up 35 by means of a screw 43 extending through an opening in the take-up 35 and engaging the threaded opening 44 in the member 4l. Thus, this long spring which is concealed within the tube acts upon and forces the take-up downwardly.

A latch control link 45 is pivotally connected as at 46 to the latch I9 and extends upwardly in a position spaced from the yarn take-up 35 and stop to a position above the yarn take-up where it terminates in a loop 47 having an opening to receive and be guided by the guide post 2l as it slides thereaiong. A spring 48 encircling the pivot for the latch I9 tends to move the engaging end of the latch upwardly and consequently move the link 45 downwardly.

The yarn 5G as it is led from the package I8 extends through a pigtail guide 5| mounted on the guide standard 2l between the upper and lower ends of the package and thence this yarn extends downwardly as at 52 beneath the hook 38 and then upwardly through the pigtail guide 53 and thence to the braiding point. As illustrated in Fig. l the yarn has just been let off from the bobbin and the take-up has dropped with the yarn to form the doubled

portion

52, 54. As the braiding occurs the take-up member 35 will be lifted by the doubled

portion

52, 54 becoming shorter until the take-up member 35 engages the loop portion 41 of the link 45, whereupon further movement will lift this link upwardly causing it to slide along the guide standard and move the latch against the action of its spring 48, whereupon the pawl will be withdrawn from the teeth I7, permitting rotation of the package and a drawing 01T of more yarn, whereupon the take-up will again be forced downwardly by its spring 39 to the position shown in Fig. 1, and this operation will be repeated as the braiding takes place.

Should, however, the yarn become broken or fail then it will fail to support the take-up member 35 which will be forced downwardly by the spring and also by its own weight so as to strike the portion 2l, 28 of the stop 25 to move it downwardly into a position to throw oi the starting handle of the braiding machine and stop the operation of the machine, the spring 3S being sufficient to overcome the spring 33 to accomplish this purpose. By this arrangement the stop is located at all times below the package and being a rather bulky and large portion when so located permits of a larger sized package to be used than were the arrangement such that the stop be moved upwardly above the lower end portion of the package.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
