Application filed August- 1921. Serial racemes:

Be" it known that we, JAMES .WIL'LIAM MonRIsoN and THOMAS WILLIAM l-lloixr, subjects of theKingof Great Br'itain-andlre fi land, residing, respectively,- at 66' Astley Street, Staleybridg'e, 1 in the county 'of' Ches ter, England, and 32 Mottram Road,'-Staileybridge, .aforesaid have invented new-wand" useful Improvementsin or Connected With Doubling, Twisting, and Vvinding and Suchlike Machines, of which the following is a specification.

This invention relates to doubling, twist. ing, and winding and such like machines,: asfo'rexample doublingframes of the kind 3 inlwhich a packagecarrier is supported on"- a spindle run ata high'speed and in which the yarn'is traversed in frontof a revolving friction drum and laid upon yapaper ;tube' or other support to.producea cheese or.

bobbin, the tube being held against the' fIld-l tiondrum'by the. action of a*weightingrde%- vice which maintains the frictionyas the cheesev is built up; 2t

metrical-cheese or the like.

\Vhen smooth paper .tubes are used, "the' friction during the'flearly' stages of winding-- 7 on. is frequentlynot adequate although the weighting motion maybe quite" adequate" during the later stages ofiviiidingonswith' sin-inadequate weight *in the, early stages,

due-to vlackf..of fproper friction, the layers. nearestto the tube may be'softlywou'nd p1 0 ducing as itwere a soft or spongy base or centre to the cheese which soft or spongy base or centre may also cause the twist to Varyat different portions of the cheese." When later,

40 as the cheeseis gradually built up gand 'the efiCtIOf the loading is adequate, the shape, of the ,cheeseis'even thereafter adversely afi'ectedbythe softbase orcentre. I A solution, which suggests itself wouldbe .45.. to use a heavier weight }'on the Weighting motion, but in efi'e'ctthis is not a solution,- because (apart from (llffiCtlltlGS 1n acco1n- According to our inventionave employ'two The object of our invention is to produce: a vei ysolidywell-wound and perfectly sync weighting motions, a "main- *weighting mo tion, and, an auxiliary or'secondary weighting'motion: which acts *upon the main.

weighting motion or otherwise upon the tube carrier for-the end 1n view,- such-aux iliary or secondary weighting motion being of such a .constructlon that during the early stagesof thewinding-on it exercises its max-' cally *diminishing .asthe cheese reaches a largerhdiameter. We can filSOSO construct suchauxiliary or secondary weighting motion that its effect may become nil when a certain diameter is reached.

The simplest solution is to use a W81gl'lt ed-leVerdevi-cte so-"fulcrumed' and so acted upon bythemainweighting motion that 1 initially "such weighted lever exercises its maximum effect,-but, aswinding-on proceeds, such auxiliary -weighted lever is so influenced as to gradually taketheweightout Of i l Wedo' not restrict ourselves as to constructionso long as this principle of increase of load initially is utilized with a gradual diminution ofsaid auxiliary load.

The attached drawings illustrate means a I for carrying out. our object according to the system aboveindicated, and in the said Fig. l is'adiagram of a type of doubling frame emplo-ying a movable weighting motion in ,co'nnection 'withleach friction drum and'shows a simple type'of auxiliary or secondary weighting 5 motion in conjunction l therewith,'the framebeing double sided, the mechanism on the F -right 'not v "being fully shown as sameis a mere duplication.

Fig.2 shows separately a broken side elevatio'nofa weighting motion with theauX- iliary or secondary l weighting motion combinedtherewith} I "Fig.3 is'a' back view of the armseen in Fig.4 shows a plan View of the slidable bar,"etc.

Fig." 5 is a detail plan;

F ig'. 6 is also a detailplan of the upper part of the weighting frameand should be examined with Fig. 2. v

The "drawings show our invention in connection 'with swing frame type of loading mechanism, eachset of which comprises a slidable bar 1 which aasses over abowl 2, througha bracket- '3' oltedto "the rail 4.

This slidable bar loaded by a load lever- 5, fulcrumed at 6, said load lever having an adjustable stud 7 which bears onthe slidable bar 1 and loads the same.

The slidable bar 1 is shown bifurcated at its inner extremity (see Fig. it thus pro- I ducing a bearing for the frame 9 allowing said frame to move angularly.

The bottom of each slidable bar 1 has a,

lug 12 for a purpose to be'described.

Supported by the spring-pieces 13 or frame-work of the machine, are small brackets 14- which have gaps for small diameter shafts 15, said shafts being fixed by pinching studs or otherwise. I I

On each shaft, and with respect to each weighting head or frame 9, we mount a shaped lever 16, the lever having an open slot 17 to fit on the shaft 15. The forward part of the lever 16 is bifurcated at 18 or shaped like .a fork to. allow, the slidable bar 1 to work therethrough whilst the rear part of the lever is a shaped weight 16". In lieu of this the auxiliary loading device may consist of a shaped casting having a rearwardly projecting shank on which an adjustable weightis carried.

hen winding commences on the tube or the like supported by the frame 9, the fork or arms 18 of the auxiliary or secondary loading lever 16 project upwards and bear against the shoulders 1 of the fork on,

the slidable bar 1 and the weight itself is substantially horizontal. a maximum loading, because the weight 16 is added to the weight of the swing load-I Asthe winding-on proceeds, and the cheese is built-up, the slidable bar 1 moves forward, and, acting on the fork or arms 18 of the auxiliary lever 16, turns same downthrough an arc and raises the weight itself through an arc, thus turning such weight sooner or later into a vertical position or one approximating thereto, at which stage, the auxiliary or secondary load;- ing device ceases to exercise any material weighting effect. The lug 12 on the slidable bar 1 by engaging the fork 18 always main tains the auxiliary loading device 16 in a true position permitting instant re-setting by pushing-in of theslidable bar 1, or, as is more convenient, by-the operator elevating the loading lever 5 when after dofling the weight. of the frame 9 and its parts cause instant re-setting.

'Our auxiliary or secondary loading device may be otherwise connected up tovthe loading swing frame.

This means Although we have referred tov the winding of cheeses such reference is only by way of example. i

The arm 8 has a prepared face 8 and is connected to avprepared face 9 on the frame 9 by a stud passing through a slot 19 in the arm 8. This permits the frame'9to assume a position not parallel with the friction drum (Z allowing of conical bobbins being supported on the spindle in the frame 9, it

being clear that by a variation in the setting of the studs 20, 20 to cause one to bear on the shaft 11 the frame 9 can be inclined or thrown out of the horizontal. I

WVe declare that whatwe claim ,is:, I "1, Inyarn doubling, twisting and winding machines a friction drum, bearings therefor, a primary weighting frame having means for supporting a package consisting of a frame, afulcrum for said frame, a slidable member attached to said frame, a ful crumed weighting device acting upon said slidable member, and automatically operative loading means combined with said sliding member for varying the constraining eifect of said automatically operative loading means during the building up of a cheese or the like.
