entre c;- .i in Si PETER HARDIVN, GF VILLMANTC, CONNECTCUT, ASSIGNQR 'T0 THE AlWERICN THREAD UOMPNY, OF JERSEY CTIJY, NEW JERSEY, A 'CORPORTEON 01? NEW Application led. December To all whom t may concern Be it known Ythat l, PETER HARDMAN, a citizen of the United `States, residing at l/Villimantic, county of Windham, State of Connecticut, have invented ja certainpnew and useful lmprovement in Twisting li/ ac hinery, of which the following is a ful-l, clear, and exact description.
The present invention relates to machines employed in the manufacture of cordage and has special reference to thread twisting' machines of the type employing a thread 'pulling head.v
An object of the invention is to provide novel means in a machine of this character for effectively preventing' undue strain be- ,ing` placed on the thread during` the twisting operation.
Another object of the invention is to provide novel means in a machine of this lcharacter for regulating the `degree of tension placed on the thread.
With these and other objects in view, the features of the'invention consist in certain constructions, arrangements and combinations of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.r
The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which,
Fig'. 1 shows a side elevation of a twister headv embodying my invention;
2 is an end elevation ofv the feed rolls and support;
Fig. 3 shows an end elevation of one of the pulling heads forming part of my invention;
Fig. 4 shows a side elevation of my invention, partly in section; and,
Fig. 5 Vshows the parts composingy the friction drive used in embodying my invention.
Referring more particularly to the drawings, Fig. 1 shows a twister head of old form with my invention applied thereto, my invention being capable of beinp; applied to any twister heads of this general type;
The twister head shown, generally speaking, consists of a spindle 1 carried by a sliding frame 2 mounted upon a slide bar 3. This sliding frame is provided with a pin 4, which works in a slot 5 in a traverse cylin- 'rwrs'irivc- Maoiiriinair.

der Gnpon a shaft 7 driven'bya worinar 8 and. worin 9, which in turn is vdriven byA a sprocket v*chain 10 from a'sliaft 11, which Iis geared bya worm fgear 11 and worm 12 to the hollow shaft 13 carrying the liier `14.
Upon the spindle 1 is mounted'the ordinary sleeve 125 driven by a slip 2pulley 16, the driving' friction of which'is due to itsb'eing` held between plate'sl?,17 ,"theformer of whichfisfpressed toward Ithe pulley 'by a spring' 18 vwhich can be adjusted by the adjusting nuts 19 2O is 'ther bobbin Yupon which the thread is to be wound, the 4same being` removably secured to the plate v17 by the headed stud 21. Mounted upon.
the art, with the exception that the arms 22 are a little longerthan those heretofore usen. in order to permit the introduction of the features embodying'` my invention.
l/Vith this old forni of mechanism a iluf v c l,
k rality of threads from suitably mounted `bobbins was passed between the feed rolls 23 and 24,v afterhavingj first been passed through ra inoistening bath 36 and after passi-nsf through the feed rolls passed over a guide 37 and throuoh'a condenser 38.
From the condenser 38 the yarn to be twisted was passed in a straightline through the hollow spindle shaft 13 to a slieave or a pulley 39 carried by the flier 14, thence passed to similar vsheaves40 and 41 from the latter ot'which it. wasdelivered directly to Ythe' bobbinQO, beine; wound `on the bobbin by the 'rotation of the .tiier. The `l/obbin is made to reciprocate longitudinally at the necessary rateby vtheaction ofthe traverse cylinder 6. and the shaft 13 carrying' the flier being provided with a pulley 42 is driven by a belt 43 from any convenient source. The sleeve 15, upon which the i `erly vof the bobbing bobbi'n 20 is mounted is driven by another belt 44 from the saine source so that the two belts 43 and 44 would have a iixed vratio to one another.
In the apparatus when thus used kthe tension due to the straight strand of yarn between the condenser 38 and the sheave 39 was due to the fact thatthe bobbin 2Ov revolves at a different rate `from that of the nflier 14, this being brought vabout by Vthe ratio ofl the pulleys driving and being driven `by the belts 43 and 44 respectively.
The tension was furtherv modified by the fact that there was a friction drive between 1 the pulley 16 and the sleeve 15, such that if thedrfag on the pulley due tothe tension of the yarn exceeded a certain amount there would be sufficient slip to prevent the yarn .frombeing overstra-ined or broken.
Furthermore, Ythe sectionv ofl the yarn which was being twisted at any one time was necessarily a long sectionA extending from the condenser V33 to 'the' pulley sheave 39. This resulted in a liability to produce an uneven twist resulting in what .is known as runny or corkscrew yarn.
In attempts to eliminate this defect, pulling heads have been provided.
In the construction.sli/own a pulling head is mounted on the forward end of theA hollow spindle 13A which consists `of a frame havingY a base-plate 45 and a'r bearing plate 46 'both formed integral with a connecting member 47, the base plateebeing provided with a central thread guide 48 and the bearing plate beingprovided with a central thread guide 49 inV alignment with the axis of the spindle 13. 'YMountedin the plates 45 and 46are :two shafts 50 each carrying on its rear end a gear Y51 and in its intermediate l portiona grooved roll 52. The gears51 are V`known commercial construction.
prior machines, however, the driving gears Y operatively connected with the rspindle 13 so that as the thread is twisted during the ro- I tation of the spindle a pull'l is exerted on the thread by the rolls 52. Y
The parts of the machine described in the foregoing may be'and preferably are of well 51 ofthe pulling rolls 52 are positively con- 'nected with the spindle 13 and in such prior f constructions it has been found that the pullcured.
In the ing devices are liable `to 'either` place an undue strain on the thread'during the twisting operation, or elsenot a sufficient amount of strain to produe the best results. To ,overcome this disadvantage of the prior constructions l have in the machine illustrated in vthe. drawings means for regulating the degree of tensiony placed on the thread by the thread pulling device. As' shown the connection between the gears 51 and the spindle 13 comprises a friction driving device constructed and arranged toenable the pulling device or rolls 52 to he retarded with relation to the spindle 13 upon an excessive Vstrain being` placed on the thread by the devices.y Also, the friction-driving device lhas provision for adjustment to vary'the degree of tension on the thread required to retard the operation of the pulling device. This connection Vbetween the gears 51 andthe spindle 13 comprises a Adouble gear, onemember of whichy engages both of the gears 51 while the other member '54"eng'ages a frictionally'driven gear wheel 55 mounted upon affixed stud 56. rllhe gear 55-is driven by the spindle 13 through a friction drive located between the two. comprises a gear' 57 mounted upon thefixed stiid 56' which drives the gear 55through friction plates 59 and 60, the latter being integral with the gear-55 and the former 59 being movable axially relatively thereto. This plate 59 is provided'vwithY a sleeve 61l which fits over a sleeve 62 integral 'with the gear '55, the sleeve (S1-:being connected with the sleeve 62 by a spline 63 so as to revolve therewith. Between the gear 57 and` theV plates 59and 60 are two leather washers *64.V Lock-nuts 66 are screw-threaded'on the hollowjshaft 62 ofthe gear 55 and a-r springV washer 65 is interposed between thenuts 66 and the friction plate 59. vThe gear'57 is driven by a gear 67 carried'by the spindle 13, As the gear 67 differs in diameter `from the gear 54` the gears 55 andr 57 diiferingfr from. each other in an inverse ratiov from the gears 54 and 67 a differential actionis Vse- As shown.-the` gearv 67 is made slightly sm aller in diameter than thegear 54, the result of this' arrangement V`'being that when the spindle 13 is in motiontlie geaifV 54 vThis friction drive lOO.
always nieves Ywith relation to the spindle provided there is noV slipof- :the gear 57 with relation to the gear 55.v lithV this ccnstriiction vit will `be al'ipafrent''that by properly" adjusting the lock-nuts 66 that upon a strain being placed on thesthread excessief the desired amountthe operation of the pulling device will be retarded fwith relation to-the operation of the spindle 13,. and thus the tension placed on the thread by the kthread pulling device may be regulated as desired. i Y
As will be evident to those skilled in. the art, my invention permits of various modiratas-ac iications without departing from the spirit thereof or the scope of the appended claims.
