SPINNING O3 TW'ISTING FRAME.

Application filed April 7,

To all whom it may concern:

Be it known that I, ALoNzo E. Rnozmns a citizen of the United States, and resident of Hopedale. county o't VJorcester, State of Massachusetts, have invented an Improve ment in Spinning or Twisting Frames, of which the following description, in connection with the accompanying drawing, is a specification, like characters on. the drawing representing like parts. I

This invention relates to ring spinning or twisting frames or similar machines in which the yarn being wound onto the yarn carrier or bobbin runs from a traveller eye. In starting the winding of the yarn the yarn frequently breaks because of the sudden strain placed upon it and this is espe cially true of very fine yarns. This is due to the comparatively long run of yarn extending from the traveller eye to the barrel of the yarn carrier which is subjected to the starting strain.

The object of the present invention is to provide means for adjusting the traverse motion mechanism so that when the winding operation is started the yarn extending from o the traveller eye to the barrel of the yarn carrier will contact with the base of the yarn carrier which usually comes closely, adjacent the traveller eye. I gageinent of the yarn with the base of the yarn carrier has the effect of substantially limiting the starting strain to the lead or run of yarn the periphery of the base which is very short distance. Immediately after the machine in operation and the yarn has started running through the traveller eye and is being wound upon the barrel or" the yarn carrier the traverse motion mechanism is restored to normal condition and the opera tion proceeds as usual.

Theobjeot of the invention is further to provide a simple and efficient mechanism for adjusting the traverse motion mechanism to secure these results. I i I These and other objects andteatures of the invention will appear more fully from the specification and accompanying drawings and willbe particularly pointed out in the claims. I' i In the drawings: I

the invention and with the: traverse motion mechanism adjusted for starting;

Fig. 2 is a detail view similar to Figl showing the mechanism in normal position; Fig. i is a view in transverse'section taken on the line 33 of Fig. 2 and looking in the direction of the arrows;

is a detail to show the position of the yarn in starting with this invention.

The invention is applicable to various types oi? ring spinning, ring twisting and similar machines and for convenience ofiL lustration is here shown in connection with atwister. As the invention relates solely to one feature of the machine it is only necessary to describe and illustrate those parts of the machine *directly concerned with the present invention;

l he "frame of ableuprights i the right-hand one' only of which is shown, between which extend the usual spindle rail 2 and arch rail 3. The spindles 4 are mounted for vertical rotation in thespindle mug and are shown. as driven by the whirls 5 in the usual manner. spindle carries a suitable yarn carrier. In

heads 7 and bases 8. the bases I v barrels and, while" these bases are be of various shapes.

The usual ring railSl isis upported upon isnr ori ice,

the machine comprises suit- Each lifterrocls, one of which is shown at .10.

These litter rods are mounted for vertical movement or reciprocation in suitable bearlngs in the spindle rail 2 and arch ra l 3.

Rings 11 aresupported on the ring rail con- 3 I centric with motion mehanism which may be of any desired pattern. Such a mechanism usually inthe spindles and each ring guides the usual traveller through which yarn carriers is thus traversed cludes a unitary quadrant lti and rocker arm '9 b lear:

14: mounted on a'transverse pivot 15. The. rocker arm t ries a roll 16 upon which rests a step 17 secured'to the bottom of the lifter rod 10. A flexible connector such as a chain l8eXte-nds over and is connected to the quadrant at one end and to suitable mechanism at the other end by which the chain is moved backward and forward. As the chainis pulled the lifter rods and ring rail rise and as the chain is let out the litter rods and ring rail descend. But in the normal operation of such a mechanism the ring rail does not descend sufliciently to allow the base of the yarn carrier to project above the top of the rings or the planes of the traveller eyes. therwise the ya n would be wound on the bottom of the barrels of the yarn car "iers.

In this invention means are provided for manually adjusting the traverse motion mechanism so that when the trameis putintooperation the ring rail will be lowered sufficiently to cause the bases of the yarn carriers or bobbins to stand well above the top of the rings or the level of the eyes of the travellers, all as shown in Fig. 1 and in detail in Fig. 4.

In the constructionillustrated as embodying a simple and preferred form of the invention the quadrant and rocker arm are mounted on a square section shaft 19 having cylindrical end sections 15 mounted in bearings in a hanger 20 secured to the bottom of the arch rail'3. As shown, the quadrant is a separate piece from the rocker arm but is rigidly secured thereto by abolt 21. The quadrant piece is provided with a rigid arm 22 extended downwardly, and in the lower end of this arm is secured a stud 23 on which is pivotally mounted the hub 24L of an anchor arm 25. This anchor arm extends up in line 7 with the quadrant 13 and to it is secured the end of the chainl8. As illustrated, the chain is providedat its end with a hook 26 and this hook is secured to the anchor arm 25 by passingtherethrough and being held in place by the nut 27.

Aneccentric 28 is rotatably mounted in the quadrant in line with the anchor arm 25. This eccentric is provided with a polygonal shank 29 by means of which it may be rotarily adjusted as by the use of a socket wrench. The eccentric also is prcvided with a projection 30 normally contacting with a stop lug 31 on the quadrant.

peration f the ns uc on w ll now When the mechanism is running under ordinary conditions the projection 30 Qfhe c en c abuts the he 31 and th ecntri; s pr iet es t e n h r arm 25 i Shown. in Fig.' 2. Under these conditions the traverse of the ring rail will not carry the bases of the yarn carriers above the level of the traveller eyes. When, however, the mechanism is to be started either after dofiing or in starting for any other reason the operator places a wrench on the shank 29 ot' the eccentric and adjusts the eccentric by giving it a turn of about 180, or to a position such as shown in Fig. 1. This allows the unitary quadrant and rocker arm 1 to swing to the right without changing theposition of the anchor arm 25, and consequently allows the lifter rods and ring rail to descend slightly. The lifter rod is so arranged that this descent of the ring rail causes the bases of the yarn carrlers to project above the level of the traveller eyes, or

bring them to a position such as shown in contact on the base of the yarn carrier to the travellereye. As soon as the yarn has oegun to wind upon the yarn carrier andthe machine is in full operation, the operator reverses the position of the eccentric, or brings it to its normal position and'the spinning, twisting or other operation proceeds as usual. p v

Having thus described the invention, what is claimed as newand desired to be secured by Letters Patents is:

1. A ring spinning or twisting frame comprising a plurality of vertical rotated spindles, yarn carriers having basesot greater diameter than their barrels mounted on the spindles, a vertical reciprocable ring rail supporting rings concentric with the spindles, travellers on the rings, a traverse motion mechanism for effecting the rec procasection of arn extending from the'point of tion or" the ring rail, and means for adjusting the traverse motion mechanism to allow the ring rail to stand at the lower limit of its traverse with the'eyes of the travellers be low the level of the top of the yarn carrier bases where-by in starting the yarn may be led from the travellers into engagement with the bases before being wound on the barrels, thus to minimize the starting strain upon the yarn.

2. A ring spinning prising a plurality vertical rotated spindles, yarn carriers havingbases ot'greater diameter than their barrels mountedon the or twisting frame com fipi ldles, a vertieal reciprocable ring rail supporting rings concentric with the spin dles, travellers on the rings, a vertically movable lifter rod for the lifter rail, atraverse motion mechanism including a rocker arm torjelieeting the movement of the lifter I rod, a traverse reciprocating connector, an anchor member mounted on the rocker arm and secured to the connector, and means for adjusting the anchor member relatively to the rocker arm to allow the ring rail to stand at the lower limit of its traverse with the eyes of the travellers below the level of the top of the yarn carrier bases whereby in starting the yarn may be led from the travellers into engagement with the bases before being wound on the barrels, thus to minimize the starting strain upon the yarn.

3. A ring spinning or twisting frame comprising a plurality of vertical rotated spindles, yarn carriers having bases of greater diameter than their barrels mounted on the spindles, a vertical reciprocable ring, rail supporting rings concentric with the spindles, travellers on the rings, a vertically movable lifter rod for the lifter rail, a traverse motion mechanism including a pivotally mounted unitary quadrant and rocker arm, an eccentric mounted and rotatably adjustable in the quadrant, an anchor arm pivoted on the rocker arm and engaging the eccentric, a traverse chain extending over the quadrant and secured to the anchor arm, and means for rotatably adjusting the eccentric thus to adjust the position of the anchor arm relatively to the rocker arm to allow the ring rail to stand at the lower limit of its traverse with the eyes of the travellers below the level of the top of the yarn carrier bases whereby in starting the yarn may be i led fromthe travellers into engagement with the bases before being wound on the barrels, thus to minimize the starting strain upon the yarn. i
