To all whom t may concern.:

Be it known that I, ALBERT EJBLAKELEY, a citizen'ofthe United States, residing at Fall River, county of Bristol, and State of Massachusetts, have invented certain new and useful Improvements in Twister- Spindle Separators, of which the following is a full, clear, and exact description.

My invention relates toseparators for twister spindles and has forfits object to provide means for preventing what is known as lashed yarn, and also to provide such means which can be readily moved out of the way Vwhen desired. Twister spindles Aare held in a bolster on aV stationary rail. lVooden bobbins are mounted on the spindles,` which pass through round openings in the twister or ring rail, which latter travels up' and down alonglthe axes of the spindles. On this' twister'railare mounted the usual rings encircling each of the spindles and small wire travelers go around lthese rings following'I the bobbin-` aiid holding'the yarn clear of the same during the twisting operation. These rings and travelers have to be `lubricated with grease", which gets very dirty in time.v When an end breaks, the loose end lashes the bobbin on either side of it. The loose end continues to throw offv the staple'- on to the bobbins on either side of the bobbin with the broken end, and this staple is twisted in, causing movable lumps. lint fillsvthe travelers Eon the ring ony either side, which causes these ends in turn to break. This will run along the rail unless remedied by the operative. ln addition to these points, the end lashes the rings and collects grease on) it, which it throws off by centrifugal force on to othernbobbins. It is such troubles that my separators are intended to prevent, and, furthermore, to prevent them without materially interfering with the other functions or manipulation of the apparatus;

The followingv is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which,

Figure 1 shows a front view of a portion of a twister embodying my invention;

Fig. 2 is an end view of the same; andk In addition,V

ings5`1-2 are members of the frame of the twister. The member Qsup'ports the twister spindles 3, the saine being provided with the usual:y drivenwhirlsl. 5 is the movable twister'rail for carryingthe ordinary rings and travelers and moving up and ydown along the'axes of the spindles'. are two. parallel shafts supported by hangeis 8 from the upper member 1 so as to Connected to 'the upper be free to trn. shaft 6 by lset screws is a series V'of sheet metal .separators 9, havingportions 10 resting on. the upper surface ofthe rail 5 so 6 and 7r as to be moved upward therebyfandfollowl i itsdownward movement. Connectedv to the lower shaft 7 by set screwsis a series of sheet metal' separators 11, which have portions 12 which engage the under side `of the twister rail, "being held in engagement therewith'by a counter-weight 18 on an arm 14 connected to the shaft 7.

. In order to be able to 'retract said separators aiidfhold them retractedwheny desired` I provide Vthe shafts 6 and l7 with arms 15 and 16 respectively'and kon those arms mount curved latches 18 and y19"ha'ving `notches 20%21, which are adapted to engage abutinents provided by holes 22-'23 in a plate secured to the .member 1 so that when either separator is sufficiently removed from the'rail 5 and retracted fromthe spaces betweenthe spindles,v yits latch willfhold fit' in y retracted position. To aid in retracting the lower separators, l provide a handle 25 fixed on the shaft 7, which extends forward so as to beeasily accessible. Y

By means of the separators above described, located between the bobbins, the

broken ends are prevented froinlashing and throwing grease on neighboring bobbinsk and are restrained from coming in contact with thesame, and, furthermore, the separators can be easily 'moved out of place, which is essential, especially when.A the bobbins are .being dofl'ed,V as there is very little room between themanyway and the addition Vof a permanent separator is therefore objectionable.

because of the fact that yon the downward motion if they were sufli'ciently long to fully protectfthebobbins, theyy would interfere with the stationary rail and other mechanism mounted on the same, and on the upward motion with the guide-board on the It is further impossible to mount separators permanently on the twister rail ble for them to interfere with the fixedy members of the twisting frame in either the upward or downward motions of the rail and yet they are of sufficient length to afford full protection to` the bobbins in any position of the rail. As the rail goes up, it pushes the upper separators ahead of it about the center of their shaft, which is so located that the separators will clear all of the lixed mechanism above the spindle top, and when the rail goes down a corresponding downward movement is imparted to the lower separators. When it is desired to move either set of separators out of the way for doiiing or other purposes, they are pushed upward or downward as the case may be and the latch drops into place in the latch-plate, holding them in retracted position.

As will be evident to those skilled in the art, my invention permits of various modiications without departing from the spirit thereof or thescope of the appended claims.

What I claim is: j

1. In a twister, the combinationV of a twister ring rail, twister spindles projecting therethrough, up and down which said rail is adapted to move, separatorsbetween said spindles normally moving with said ring rail and movable rearwardly out of the spaces between said spindles said separators being' located b elow said ring rail.

2. In a twister, the combination of a, twister ring rail, twister spindles projecting therethrough, up and down which said ring railis adapted to move, separators between.

said spindles and located below said ring rail and normally moving withsaid ring rail and movableout of the spacesvbetween said spindles, a` revoluble shaft to which said separators are connected, andmeans forV holding said shaft when turned so as to retract said separators from said spaces.

3. In a twister, the combination of a twister ring rail, twister spindlesprojecting therethrough, up and down which said rail is adapted to move, two setsof separators between Said spindles normally moving with said ring rail andmovable out of the spacesl between said spindles, said separators of one set being` connected together and located below and-the separators of the other set being connected together and located above said ring rail, and means for retracting the separators of either set simultaneously. j

4f. In a twister, the combination of a twister ring rail, twister spindles projecting therethrough, up and down which said rail is adapted to move, two sets of separators between said spindles normally moving with said ring rail and movable out of the spaces between said spindles,`one set of said separators `being located below and the other above said ring rail, :and both sets normally tending to move toward said ring rail under the action of gravity.

, 5. In a twister, the combination -of a twister ring rail, twister spindles projecting therethrough, up and down which said rail is adapted to move,two sets of separators betweensaid spindles normally moving with said ring rail and movable out of the spaces between said spindles, one set of said sepas rators being' located below and the other above said ring rail, revoluble shafts to gaged by said latches to hold said separators when retracted from spaces.
