BRAIDING-MACHINE.

Specification of Letters Patent.

Patented Feb. 25, 1919.

To all Whom it may concern:

Be it known that I, CHARLES E. T RAxnL-, a citizen of the United States, residlng at Rome, in the county of Oneida and State of New York, haveinvented an Improvement in Braiding-Machines, of which the following is a specification.

In braidirig-machines for covermg w re with silk, cotton and other threads, automatic means have been provided for stopping the machine in case a thread breaks, said means usually consisting of a weight adapted to be lifted by the thread when the thread is pulled taut, and arranged to act by gravity when the thread breaks, thereby to control the operation of a stop-motion or clutch for the machine.

The threads are rapidly drawn from supplies arranged on supply-holders, and in Letters Patent #1,058,206, dated April 8, 1913, granted to me, each supply-holder has a tension-device in the form of a frictionbrake which engages and exerts a moderate pressure upon it, whereby its rotary motion is resisted, but not positively restrained or checked, and a take-up arm for the thread movement of which is opposed by a spring, is arranged to be engaged by the thread and to be operated by a ull upon the thread, and

when raised to a predetermined position to move the friction-brake will relieve the tension on the supply-holder, thus admitting of sudden withdrawals of thread from the supply-holder, which movements are yieldingly resisted, and as a result the thread will not be broken even when the machine is being driven at high speed.

The present invention has for one of its objects the provision of a controlling-member for the stop-motion or clutch-mechanism of the machine, which is arranged to be operated by said take-u arm, in case a thread breaks and said ta e-up arm resumes its normal position to control the stopping of the machine.

Another object of the invention is the construction of the controlling-member, adapting it to be moved positively in both directions by the take-up arm.

Figure l, is a side-elevation of a traveling carrier for braiding-machines embodying this invention, the take-up arm being in partial elevated position.

Fig. 2. is a front elevation of the same.

Fig. 3, is a detail showing the take-up arm in full elevated position with the frictionbrake disengaged.

" Fig. 4, is a similar detail showing the takeup arm'in its normal or lowermost position, and the controlling-member for the clutchmechanism, operated to cause disengagement of the clutch.

Fig. 5, is a plan view of the traveling-carrier (the supply-holder being removed) and having a circularly formed base 14. Suitable means are or may be arranged at the.

top of the post to prevent axial movement of the supply-holder. 40 represents the takeup arm for the thread 41, and has a hook 42, or other means at itsextremity for engagement with the thread, which thread passes over a hook or. other means arranged on an upright post 35 on the traveling-carrier. Said take-up arm is secured to a pivot-shaft 43, which extends through a hole in an arm 7 O, and which has arranged on it a spring 44, attached at one end to it, and at the other end to said arm 70, said spring acting to move the take-up arm in a downward direction, and thus oppose its upward movement due to a pull upon the thread.

The end of the spring may be adjustably attached to the pivot-shaft, as for instance,

by arranging a disk on said shaft, havin g' notches in its periphery, and arranging the end of the spring in any of said notches.

The take-up arm, as here shown, has a projection 46 arranged to engage a projection 47 on the carrier-frame to limit its upward movement. Also, as here shown, it has a projection 48'arranged'to engage the controlling-member of the stop-motion or clutch of the machine. Said controllingmember is made as a bell-crank lever comprising an upright arm 60, and a laterally extended arm 61, and is pivoted to the carrier-frame at 62. It also has a heel-extension 63, for limiting its movement in one direction, see Fig. 3. and its movement in the other direction is limited by the upper end of its arm .60, striking against the side of the arm 70 or any other stop, see Fig. 4. Its laterally extended arm 61, has a forward projection or ear 64;

When the take-up arm is in its lowermost position, see Fig. 4, it engages the projection 64, and is thereby prevented from further movement, and the projection 48, on said arm extends over the top of the projection 64, and thus acts to prevent movement of the controlling-member into its other position. The take-up arm and controlling-member will occupy these positions when the thread breaks. Vhen the take-up arm is lifted by a pull upon the thread, see Figs. 1 and 3, its projection 48 is moved into engagement with the side of the upright arm 60, and acts to move the controllingmember on its pivot, thereby to raise the projection 64, to permit engagement of the clutch; and said controlling-member will be 7 positively held in this position during the time the take-up arm is thus lifted, but when the thread breaks and the take-up arm resumes its normal or lowermost position, its projection 48 will engage and positively move the laterally extended arm 61, thus moving the controlling-member on its pivot. The projection 64 is thus moved into position to cause disengagement of the clutch. It will be observed that the controlling-member is moved positively in both directions, and also is positively held in both of its positions.

One form of stop-motion is here shown for the purpose of illustrating one embodiment of my invention which is arranged to be controlled by the controlling-member here shown.

Referring to Figs. 5 and 6, the projection 64 of the controlling-member is arranged for engagement with the curved end-portion 65, of a holding lever pivotally mounted on a stud 66, the other end-portion of which lever has a latch-formed extremity 67, for engagement with a pivoted clutch-lever 68.

The clutch-lever has a spring 69 attached to it by which it is moved to slide the clutchmember, and thereby disengage the clutch, and said clutch lever is adapted to be held in clutch-engaging position by the holdinglever with the latch-formed end which engages it, and to be moved by its actuating spring when said holding-lever is moved out of engagement with it. Said holding-lever has a spring 91 connected with it to provide a yielding connection for it. When the controlling-member, which is operated by the take-up arm, is in its elevated position, as represented in Figs. 1 or 3, its projection 64 occupies a path of movement above the curved end-portion 65 of the holding-lever, in consequence of which said holding-lever is held in en agement with the clutch-lever, therebv to hoid said lever in clutch-engaging naeaesa position. When the thread breaks and the take-up arm resumes its normal position said controlling-member is moved, and its projection 64 enters a ath of movement for engagement with said curved end-portion, and upon engaging said portion, acts to move the holding-lever to disengage the clutch-lever and permit disengagement of the clutch.

Thus it will be seen that the clutch-lever may be moved by hand into clutch-engaging position, and the machine started, and that said lever will be held in such position by the holding-lever, which is arranged for engagement with the controlling-member, adapted to be operated by the take-up arm when the thread breaks, thus automatically stopping the machine.

The arm 70, to which the take-up arm is pivotally connected, is here shown as the pivoted supporting-member for the frictionbrake for the supply-holder. Referring to Figs. 1 to 6, the friction-brake is constructed and arranged for cooperation with a metallic supply-holder having a circularly formed base with a corrugated flange, the inside of the flange being employed as the brake-engaging surface. In the structure shown in said figures, the arm 70 is pivoted at its lower end to an ear on the carrier frame, and has a projection 71 at its upper end which is adapted to engage the side of the corrugated flange, and said arm 70 is movable in the directiontoward the left, Fig. 1, by the spring 44, thereby to engage said flange. The force of such engagement is gradually increased as the take-up arm is lifted until such time as said arm is positively moved out of engagement .with the flange. The take-up arm has a projection 72 arranged near its pivot, which, ,when said arm is raised high enough, will engage a fixed pin 73, on the carrier-frame, and by further movement and consequent pressure upon said pin, said arm 70 is moved on its pivot in the direction toward the right Fig. 3,- and its projection 71 moved out of engagement with the corrugated brake-engaging surface. It will be noted that, as one end of the spring is attached to the pivot shaft and the other end to the arm 70, that, wrfhen said spring is adjusted rotarily and the pivot shaft turned by the take-up arm, the force exerted by the spring will have a tendency to move the arm 70 on its pivot in a direction toward the left of Fig. 1. The tension of the spring is suflicient to act to move said arm 70 in such man ner not only when the take-up arm is lifted, but also when the take-up arm is moved into its lowermost position. due to thread breakage, as shown in Fig. 4. However, in so far as the operation of the controlling-member for the clutch-mechanism by the take-up arm is concerned, the friction-brake may be omitted, or, if employed, may be constructed in any other manner, hence a modified form of friction-brake is represented in Figs.v 7 and 8, which is adapted for a supply-holder of another type. In this instance, the supply-holder has a circularly formed base with notches on its under side, and the member 70, to which the take-up arm is pivoted, has an extension arm 80, with a projection 81, thereon, arranged for engagement with and disengagement from the notches. It isobviou's that the operation of the parts is the.

same when the thread runs out as when the thread breaks. I
