To @ZZ 'whom t may concern:

Be it lrnownthat d, NILLme/i ,lgleiir, .a citizen ofthe United `States, `residingat South Barre, in the county of 4,flforcester and State of ll/.la-ssachusetts, have invented `new and useful Attachments for VVorsted Top ishers, Jof. which the followingisla :specificii e tion.

This invention relatesto a .device vfor use in helling'l the sliver `on a worsted top linw The principalohjeets of the invention are to lmake anlexceptionally ,goed lookin-g .top for the market and yalso ,to provide improved means for putting a uniform falsetwist into the sliver so that the hall :will 19e-compact and loose `strands will ,not he left-.on ltlietop in unwinding in the drawingroom, thus avoiding one .of Vthe prin-cipal causes of the @conetant :breakingof lthe sliver; alsolto provide a `construct.ion in which entanglements are avoided when lunwindine;` in the .drawingoperation; :and Vto provide an `easy running and positive driving mechanism for @operating the same. Further objects and advantages ofthe invention will appear hereinafter. Reference 1is Ito ilse 4had to the l1accompany .ing drawings, in rwhich Fig. 1 is a front view of an attachment constructed in Vaccordance with this invention for use on atop finisher.;

Fig. `2 is a plan ofthe same, and Fig. Sis ya sectional view through the center of one of the funnels.

As is -well understoodlin the wool nishing art, the sliver after it .comes from the 'comb istaken to a hoXin--the formlof a` can :where itis gilledand conditioned. Thenit is taken from :this box to the worsted top finisher where the last `operation in the combing department is performed. Un the top-linisher there is a hailing head lhv means of which `the .sliver is wound into halls,

This invention is designed to doe applied to the top iinisher'and to control the sliver as it `passes from it tothe halling head.

@neef the functions which it performs is to providea false twist, that is, first atwist in one direction and then in .the other, in the'sliver sothat the same is kept taut-and yet tlere is no real twist putinto the sliver that will affect itwhen it is unwound, the two twists neutralizing each other. The loalling head on the finisher which travels back and forth furnishes all the Vpower forthe attach ment. i

The traveling .hailing head plate 10 reciprocates hack and forth in the ordinaryina chine. The means for operating `it l have not illustrated herefas it doesnot constitute a partfofthisinvention lt is` provided with a holt 11 or other 'fastening device which has' secured ,to it a frame 12. The opposite ends of a chain `13 are secured to :this frame to provide what is in reality an endless chain. This' passes over an idler `sprocket wheel 14 on `a shaft 15 and `a power transmitting sprocket wheel 16 on a `parallel shaft 17. The reciprocation of the plate 110 will oscil-- late these shaftsl' and 17 and cause each of them to turn several revolutions one wayand then la corresponding number of revolutions in the other way. Asthe drive `is `positive and `there is noslippage 4there is 4no `lost mo tion in starting or stopping and no ydan,.;er of providing more rotation in one direction than inthe other.

The shaft 17 is provided with a sprocket wheel 18 largerthan the wheel 16. Over the larger wheel passes .an endless sprocket chain `19 which meshes with two sprocket wheels 20, each mounted on `a rotatably mounted funnel 21. rlllhese funnels are mounted in hearings 22 on the frame 23 as is usual except that they are provided with ball 'hearings to reduce `the friction. Each funnelis constructed in the usual way having an enlarged inlet for` guiding' the strands of thesliver into it. The. butt is provided with an opening;l 25 therethrough for discharging thelsliver, this opening being arrangedldiametricallv and having flat oppositesides butintended at the center to form a shape similar to aligure d and remove dead space or non-revolving arealas muchas `possible, This-guides the sliver out to the rolls 26 on which the ball 27 `is Aformed in the usual way.

It will loe `seen .that any movement given the sprocket wheel `16 is multiplied by the connections to the vsprocket wheels 20 and funnels 21, lout the `motion is always positive as stated above and the twist in both directionsis alwavs'the same. Thisprovides a positive multiple false twist and improves the appearance and condition of the final product, that is, the ball.

The sliver is kept taut by the fact that the amount of twist is greater than usual and there is not much chance .ot a tew strands being lett on the top in unwinding in the drawing room. Therefore, the breakage is materially reduced. It produces a well made solid top holding its shape under rough usage and tree trom entanglements in unwinding.

It is to be observed that the so-called oscillation does not consist in a mere turning motion through a small arc but, where4 it attects the sliver, that is at the tunnel, it consists ot a rotation ot the tunnel through a plurality ot complete revolutions in each direction. This need not be a plurality ot exactly completerevolutions but it is more than one complete revolution and it may involve several complete ones and a part ot one in addition. This would be according to the proportions ot the gearing. But at any rate the rotation in each direction is equal and, being positively driven, there is no way that, on account ot slippage or the slowing up ot the motion at the end ot the stroke ot the balling head plate, there can be any inequality in the twist. Therefore, when unwound trom the ball all the twists will eX- actly neutralize/each other. On account ot having more than a complete rotation in each direction also the sliver is laid on the ball in a more even and compact manner than has been possible with the mechanisms heretofore known.

Although I have illustrated and described only a single torm ot the invention I am aware ot the tact that modilications can be made therein by any person skilled in the art without departing trom the scope ot the invention as expressed in the claims. Therek tore, I-do not wish to be limited to all the details ot construction herein shown and described but what I do claim is 1. The combination ot a worsted top iinisher having a balling head plate reciprocably mounted thereon, with a tunnel and positive means tor transmitting the reciprocating motion ot said plate to the tunnel at all times to rotate it a plurality ot revolutions in one direction when the plate moves forward and a plurality ot revolutions ot exactly equal amount in the other direction when the plate moves back.

2. The combination ot a worsted top tinisher having` a balling head plate reciprocably mounted thereon, with a pair ot tunnels located parallel with each other, and positive means tor transmitting the reciprocating motion ot said plate to the two tunnels at all times to rotate each ot them a plurality ot revolutions in one direction torward and a plurality ot revolutions ot eX- actly equal amount in the other direction when the plate moves back.

3. In a worsted top finisher, the combination with the reciprocating balling head plate, ot an endless chain movable therewith, a sprocket wheel over which said chain passes adapted to be oscillated by the operation ot the chain and plate, a pair ot tunnelsr tor the sliver located parallel with each other, and means tor transmitting the oscii- 'f lating motion ot said sprocket wheel. to both ot said tunnels to oscillate them simultaneously at a higher speed than that ot the chain.

4f. In a worsted top finisher, the combinaY tion with the reciprocating balling head plate, ot an endless chain secured thereto and movable therewith, a pair ot sprocket wheels over which said chain passes, whereby they will be oscillated by the operation ot the chain and plate, a pair et :tunnels l'or the sliver located parallel with each other, and means tor transmitting the oscillating` motion ot one ot said sprocket wheels to both ot said tunnels to oscillate them simultaneously, and tor multiplying the motion to cause the tunnels to rotate a plurality ol revolutions at each oscillation et the lirst named sprocket wheels.

5. In a worsted tcp linisher, the combination with the reciprocating balling head plate, ot an endless chain movable therewith, a pair ot sprocket wheels over which said chain passes adapted to be oscillated by the operation ot the chain and plate, a pair ot tunnels tor the sliver located parallel with each other, a shatt on which one ot said sprocket wheels is mounted, a sprocket wheel ot larger diameter on said shatt, a pair ot sprocket wheels on the tunnels ot smaller diameter than the large wheel, and a second endless chain passing over the last three wheels.

6. The combination with a reciprocatorv balling head plate ot a worsted top finisher, ot a shatt, means connected with said top plate tor oscillating said shatt as the plate reciprocates, a sprocket wheel on said shatt, a pair ot tunnels each having a sprocket wheel thereon ot smaller diameter than the iirst named sprocket wheel, and an endless chain connecting the three sprocket wheels to rotate the tunnels a plurality et revolutions whenever the shatt is rotated one revolution.

7. In a balling head tor a top finisher, the combination ot a tunnel and means connected with the finisher tor oscillating it positively aA plurality ot revolutions in each direction, with a guide in the tunnel having a passage located diametrically and con tracted at the center on opposite sides tor the purpose described.

In testimony whereot I have hereunto atliXed my signature.
