JOHN P GAREY, OI ELMIRA HEIGHTS, NEW YORK.

"SPINNING AND THE LIKE.

Application filed April ,28, 1921. Serial No. 465,236.

Toall whom it may concern:

Be it known that I, JOHN, P. GAREY, a citizen of the United States, residing at Elmira Heights, county of Chemung, and 5 State of New York, have, invented certain new and useful Improvements in Spinning Frames and the like. 2

My invention ,relates to spinning frames and the like and the object thereof is to provide simple and efiicient means for stopping the feeding of rovings through the drawing rolls after, the thread or yarn has been broken. The main object of in'y invention is to provide simple and reliable means for said purpose, the advantages in the construction and mode of operation of which will be apparent from the description hereinafter given.

In the drawings Fig. 1 is a vertical section through a portion of the spinning frame embodying my invention; Fig. 2a plan view thereof; Fig. 3 anelevation on a larger scale illustrating my stop means and showing a portion thereof broken away; Fig. t an enlarged view of certain parts shown in Fig. 1; Fig. 5 a section on the line 5-5 of Fig. 3 and Fig. 6 a detailed view of a portion of a stop block and its operating arm. The spinning frame may be and is shown as of 30 the ordinary type and comprising suitable frame members including a board or table 10 on which are arranged a large number of spinning units in the usual manner. The spinning mechanism proper includes a spindle 11 rotated suitable mechanism (not shown) on which is mounted a spool 12 to receive the thread or yarnpa ring board 13 constructed and arranged to be reciprocated vertically in order to carry the ring 14 and traveler 15 thereonlongitudinally of the spool during the winding operation.

The usual drawing rolls are employed, the same comprising three pairs of rolls 16, 17 and 18 revolved at progressively increasing speeds so that the rovings are drawn or lengthened bythe relative movement of the fibres between successive pairs of rolls. A scavenger roll 19 is also employed to cooperate with the rolls 18. Supply bobbins 20, of which there are one or more for each set of drawing rolls, are mounted behind these rolls in position to feed the rovings thereon to the bite of the rolls.

The rovings -21 and '22 from the supply "bobbins Y are carried through a trumpet guide 23 to the-first :pair oft-drawing rolls 16,

thence through the, rolls 17 and 18 to the eye or, guide 24- which is arranged in the axis of rotation of the spindle 11 and from which the thread is carried through the traveler15 and thence to the spool 12'. The guide 23 is mounted upon the usual reciprocating slide bar 25 which extends longitudinally of the frame and is common to all of the sets of draw ng rolls, such slide being reciprocated by suitable mechanism, not shown.

The. horizontal bar 26 performs its usual functions of supporting the bearings of the drawing rolls. y

Except forthe specific form and mounting of the guide 2 1 hereinafter described in detail, the mechanism as thus far set forth is that which is common to most spinning .ma-

chinery and therefore need not be further described.

Referrlng to my stop mechanisimthe same comprises means for gripping the rovings after one or more of them or the thread or yarn has been broken, which mechanismis operated by controlling means whose action is dependent upon the continuity of the thread in such guide.

My stop mechanism is located between the bobbins and the drawing rolls and is supported by the bar 26. i

As herein shown the stop mechanism comprises a block 27 which has a recess 28 whereby such block is fitted over the bar 26 and removably and adjustably secured thereto in suitable manner as by means of these; screw 29 passing through one side of the block and bearing against the bar 26. A plate 30 is secured to the block insuitable manner as by means of the screw 81, such separate construction being preferred although the block and plate Inightbe made integral. This plate terminates atits upper I end in a rearwardly eXtending'flang-e 32 which acts as a protective covering. A flat bar or plate 33 extendsparallel to the plate 30 and s attached thereto by THGSHS of the screw 31 and pins passing through the two plates. This plate 33 is providedwith guides 35 for the rovings, two suchguides' icet on 1'. )a'einas 1 11s tie being piov l l tl is l t nu cl '1 1 stop means being descrlbed is capable of ac commodat ng two spinning units.

Between the two plates 30 and'33 and on i v gripped in said opening 38 and against the inner side of the plate 33, thereby preventingany further drawing of the yarn from the bobbins. The movement of the stop block 36 is limited in both extreme positions by the stop pin 39 which will bear against the top edge of the plate 33.

These blocks 36 are controlled in their operation by certain trigger ,mechanism dependent upon the position of theguide 24,

which is in turn dependent upon'the contlnuity-of the thread or yarn. Referring to t-he controlling means, the same carries at its forward end the guide Qatand at its rearward upward end a device'cooperating with the lower endof an arm 40 which is pivoted at its upper end in a slot i1 in the lower end of the stop block, there being of course two of these arms 40, one for each block" of the structure above described. Each armiO is preferably of the construction shown, particularly with respect to the provision of a shoulder 42 thereon cooperating with the pin 43 for imparting to the block 36 its movement in one direction. Each arm carries at its lower end an adjustable trigger 4L4 terminating in a curved trigger proper indicated atferi) whose angularity is adjustable with respect to its arm 44: and which latter arm is itself ad-; justable by reason of being attached to'the arm to by the screw 46, as detailed in Figs.

3 and 5. r 7

Referring to the details of the controlling means, the guide 24; is adjustably connected by the sleeve 47 and set screws 48 to arod 49 which is pivotally connected at 50 in a bracket or support 51* mounted on the table 10. .This rod 49 carries at its rearward enda weight 52 adjustably secured thereon'an'd such rod also passes through and is secured to a horizontal cylinder 53 whichin turn is provided with a vertical rod 5e carrying acylinder The cylinder 55 is provided at its upper end with a; rod 56 curred at its upper end and adapted to cooperate withthe trigger e5.

When the parts are in the normal position showniin Fig. l the stop blocks 36 are in their normal. position such as illustrated ;by the left hand one in Fig. 3 at which time such blocks are 'overbalanced inwardly and stopped in such position by contact of pin '39 with plate 33. However, iftheyarn or roving,

thread should break or the normal. and

means areadjusted so as to be in substantial balance or in equilibrium or preferably slightly overbalanced 'backwardly so that when the tension has released from the guide as the latter will move upwardly as stated. As a result the rod 56 will contact the triggereiS and move the same inwardly thereby swinging its stop block 36 downwardly to a position where the same will be overbalanced whereupon such block will drop instantly and rapidly upon the yarn passing through the guide 35 thereby clamping the roving in the manner as hereinhefore described. -The pull of the drawing rolls will then break the fibre of the roving and feed from the roving bobbins ceases so thatthere can beno injurious accumulation of roving on the drawing or scavenger rolls. The operator thereupon restoresthe stop block to normal position and rethreads the unit.
