The general object ofthe present invention is the provision of a regulating apparatus which will .greatly facilitate the installation 10 and fitting and proper co-ordination of the speed regulating machine. v 7

Another object is the provision of means for adjusting the timing relationshipof the machine and'actuating motori means with the spinning Other'and further objects will'bepointed out or indicated hereinafter, :or obvious to of the present disclosure. g

It will. be understood that in accordance with the disclosure of the above mentioned one skilled in the art "upon an understanding patent, provision ismade for varying the speed of the driving motor in accordance with the movement of the ring rail of the spinning machine', such variation in speed bemgaccomplished through the medium of properly formed cams which are operated in accordance' with the vertical movements jof the ring rail during operation. One cam operates in accordancewith the reciprocating movementof the ringrail which takes place repeatedly duringjthe spinning'ofthe yarn and its winding on the successive conicallayersof I the co andthe other cam is operated in accordance with the progressive movement of the ring rail as it is raised to build up the entire cop. Heretofore it has been necessary to form'the cams speciallyfor each installation,

which has required a cut-and-try procedure involving individual filing of the cams in order to give them the proper shape and size to obtain the desired speed regulation.

' cedure in installation,

The present invention obviates the necessity of-this troublesome and expensive proby making it possible to use cams of standard or uniform profile and obtain the regulating eifect desired in the several installations, by means of adjustable interconnecting means between the cams and the motor regulating device.

. In theaccompanying drawings formingaa part-of this speclficationis shown one form of device representing an embodiment of the invention, but it is to be understood that the same is here presented for illustrative purposes only as the invention is susceptibleof embodiment in many other forms all within the-scope of the appended-claims.

* In the drawings,

Fig; 1 isan elevational view of the ap'para tus showing the cams in oneposition;

Fig. 2 is a similarelevational view showing details showing various stood, that the numeral'lO, designates a shaft which is rotated in accordance with the reciprocatingv operation of the ring rail, and 11 designates another, shaft which is operated in accordance with'the progressive movement ofthe, ringraila The shaft 10 carries the cam 12 and the shaft '11 carries the cam 14, the profileforms of which are designed with respect to the intended speed variations. The

speed control or guide lever is formed of'the portions 15 and 16, both pivoted on the'centre 17 and have anadjustable connection by means of set screw ries the'roller 19' which bears on the profile of the cam 1'2 so that the guide'lever rocked by rotation of the cam.

On the centre 20 is lever 21 which is-con'nected at one end with the element 22 whichoperatesthe speed varying means of the motor which operates the spinning frame. Pivoted to the other end of the regulating lever 21' is the transmission link 24 which carriesat its lower end the roller 25 which'bears on the arcuate margin the fguide lever 15." By virtue of this con- 18, whereby their angularitymay be varied. The portion 16 cari can vbe' pivoted the regulating" nection, it will be seen, the rocking of the V guide'lever will be e'ttectiveto rock theregulating lever 21; The lever 26 is pivoted von the centre 27 and carries at one end the roller '28 which rides on the profile'of the cam 14.

The other 'end of-the lever 26 is pivoted to a sleeve -29 whichforms a mounting for'the I elementwith'respect to said-edge,:means pro.

viding :an' operative connection between said upon" the control lever:2l may bervaried by the adjustment ofthe screws 80 and118-Thei adjustment of the screw 30 varies the efiective lever arm m of the guide lever bywhich-the movement ofthe roller 19 is transmitted to the link 24, regulating lever 21 and reg'ulat ing connection 22.- Theshorter m is, the

smaller will be the displacement of the .regu}- lating connection 22 and consequently, the

less will be the-amplitude of the periodic speed variation of. the motor attendant'upon the reciprocating movement of the-r1ngra1l.

The adjustment-ofthe screw 18 is efiective to; vary the total height of the-speed curve, i. e.,-. the base speed of the motor, for 'a given spinning. operation. Accordingto'the angularity of the guide lever arms 15-and16', the nor-- mal position of the roller 25- will be :higher or lower, resulting in' the positioningot-the regulator connection 22 to obtain a higher'or ning machine .includingga V adaptedfo'roscill :tocontrolthespeedof' lower basic motor speed. p Y j Fig, 2 shows'the relative: position 1 of; the

parts at the point of minimum cam throw,

as distingulshed from Fig. 1 which shows,

them atthe point of maximumcam ,throw.'

In Figs. 3 and4c-are shown other-arrange ments for accomplishing adjustment ofythe? guide lever, 'wherein the adjustmentuiseace complished by displacement of the fulcrum In the form shown in Fig; 3 the ofthelever. lever is fulcrumed on a sliding-.blockfill' which is adjustablein its mounting by,means of thescrew -18, while'in Fig. 5tthe'lever is eccentrically fulcrume'don a rotatable .member 17 whichis held in-position by the screw 34;. f

By virtue of the improved control arrangement, not onlyarethe cost and inconvenience of specially formingand filing the cams foreach installation obviated, but also a desir able flexibility and latitude obtained for variation of the speedregulation as desired for difierentconditions of operation or-zoutput.
