' loathe/tom it may com-( 1')! ,jBe it known that I; Ennnn'r Josue. a citizen of the l 'nited States, an(l a-resident o fQDanville, in .tbe' county of Pittsylvania and .State of Virginia. have made certain. new, and useful Improvements in. Spinning Machines, of which the following is aIspecification. i l

Y, My invention relates to improvements in spinning machines. and it consists in the cQmbinations, constructions and arrange. ments herein described and claimed. ;In ;the spinning of .yarns. the bobbins nponwhiclrthe. yarn is wound have a primary winding which is termed the bunchf. This winding extends for a certain distance upwardlyfrom the bottom of the spindle and necessary for the purpose of providing an engaging" member for a feeler il IlCilLPIQVQHiZS the danger of winding oft of -all the,yarn on. the bobbin ina manner ivjell' known to the art. This so.-ca.lle,d fbunch'l. represents ust so much waste yarn orthread and is a considerable source of loss since .with the large number ot' bobbins theiamount of yarn or thread which is consumed. making the bunch amounts to a very substantial item of expense.

,A robiQet-oi my invention is to provide a device by means of which the amount'iot yarnionthefbunch may be reduced tb app iminfiately. one-half or even less, thereby economizii-ig in the amount of" yarn which \YQlllF L I I fnrtherobject of my. invention is to providea device of the type described which will'form a tbunch of less yarn or thread, becausethe throw or stroke of the guide rail is reduced by my invention. whileat the same-ftime .means is provided for permitting ai normal stroke or. reciprocatory movement. of the. guide; rail whennthe fbunchl has been formed. A further; object ot myinvcntion. is to provide, a. device byinieans .of which. the ementof. theguide rail maylm lessened. this movement H hem 5 putting sail auxi a ry cam out of opera ion and for bringing into operation the main cam which controls the movement of the rail in forming the remainder of the Winding on the bobbin.

i Application filed December 30, 1914. Serial No. 879,770.

provide a simple device of the type described whiclrmay be applied to existing spinning machines without the necessity of dismantling the machines in any way or of machine. i

:Other objects and advantages will appear in the following specification and the novel interfering in the ordinary operation of the features of the invention will be particularly pointed out in the appended claims. My inyention is illustrated in the accompanying drawings forming part of this application in which Figure 1 is a plan view of the device as applied to a spinning machine. Fig. 2-is aside.view thereof. Fig 3 is an end view of the device showing 'its application to a spinning machine. Fig. "-l is ai face view showing, the relation of the cam and the main cam, Fig. is asectional' view along to Fig. 9. showing the a-uxili ry cam in another position.

in explaining my invention it is necessary for me to describe and show certain parts of a, .common typef spinning mechanism in order that the improvement maybe readily understood. .1 will describe; however. only so much of the old structure as isnecessary for a, thorough understani ling of my. improvement; 1 i

Referring especially to Figs. 3, and 7, I have shown therein a main frame 1 *upon which is mounted astub shaft 2 bearing a builder aarinfi to which is secured a sprocket chains which is attached at 5 to the arm andzwhich passes around an idler 6 on a slidable plate carried by the arm, thenceover infe tom. bellrlrank levenl igwhichk isapivotedat 13 and whose arm bearer-on a vertically slidable push rod 14 which is guided in bear- E'igs or slots 15 and which bears at its upper end a rail 16 whose reciprocal vertical movement is designed to guide the thread or yarn upon the bobbins such as that shown at 17 'in F 1;. Secured at the end of the power shaft 15 is a cam 19 which beans on a roller 20 on an adjustable plate 21 carried by the arm J.

As is well known in this art the winding oi the yarn upon the bobbin 1? is accomplished through the aid of the guide rail 16, beginning at the bottom of the bobbin and guiding the thread up and down 'for a raise. and lower. The progressive motion is caused by a ratchet wheel 22 at the endof a shaft '23 which is rotatably carried by the arm This shaft bears a plate 38 which is loosely mounted thereon and which carries a pawl 23 arranged to engage the ratchet wheel A fixed member A is disposed in the path of the pawl so as to bring the latter into engagement with the teeth of the ratchet wheel-at each upward movement of the arm 3, thus causing the rotation of the ratchet wheel at aoh upward movement. ()u the'shat't 25 is disposed a worm it; which eugagcsa slidable rack member 27 that bears an idler (i. It will be seen that as the ratchet is turned the worm 26 causes a movement of the plate 47 so as to slackcn-up the chain 4 and thus permit the pull rod 28 which operates the bell-crank higher.

levers lever to move the push rod progressively The stroke of the push rod 14, however. will be the same since it depends upon the shape and size of the cam 19.

The parts thus described are old and form no partof my invention except in so far as they (:oiipcruto with the parts about to be described.

Referring particularly to Fig. 2 I have shown therein a bell-crank lever which is pivoted on a stub shaft 29 carried by a plate 30 secured to the arm 3 by bolts 31 or in any other suitable manner. ()ne arm 32 of the bell-crank lever bears a roller 33, the other arm 32" being connected by means of a link and turnbuckle connection 34. with a link 35 which is mounted on a pivot bolt 36 carried by the arm 3. The position of the bell crank 32", 32", and hence of the. cam roller :33, depends upon the position of the stop member 36*. When the bell crank lever is in its eli'ective position. the stop 36 bears against the arm 32". The stop Mi -is carried by the plate Wand moves with it as the latter is moved by the worm 26. On the power shaft 1 mount an auxiliary cam'37 which, as will be seen, is smaller than the cam 19. This cam 37 is arranged to bear on the roller 33 when the hunch is being i made, the main cam 19 also being in operation during the building of the bunch, but the device is so arranged that the main cam 19 alone comes into play for the further winding of the bobbin, as will be explained later. As stated before the shaft 25 bears a loosely mounted plate 38 which carries a pawl 23 which engages the ratchet wheel 22. A second plate 38' which bears a stop pin 39 is loosely mounted on the shaft 25 and is provided with an extension 38 carrying a set screw 38 (see Fig. 1) which extends through a slot 38 in an enlarged weighted portion 38 of the plate 38'. This construction forms a means by which the. relative position of the pin 39 with respect to the pivotal support of the pawl 23 may be varied. This pin 39 extends underneath the pivotal support 36 of the link From the foregoing description of the various parts of the device the operation thereof may be readily understood. The purpose of the auxiliary cam 37 is to shorten the stroke of the large cam 19 while the bunch is being made. The cams are placed in the relative positions shown in Fig. 4 so that during the rotation of the shaft 18 which bears the cams,the auxiliary cam 37 will at times engage the cam roller 33 so as to move the arm 3 from the control of the cam 19 and thus cut thestroke in two or shorten the stroke while the hunch is being made, as will be explained later. The normal position of the roller 33 at the beginning of the winding operation is that shown in dotted lines in Fig. 2, or that shown in detail in Fig. The roller 33 is held in this position by the engagement of the arm 32" of the bell crank lever with the stop pin 36 which, as stated before. is carried by the plate 27 and which at thebeginning of the operation is in the position shown in Fig. 9. It will be understood that the arm 32 gradually recedes, as explained lateryfrom the position shown in Fi g. 9. which finally allows the high arts of the cam 19 to come into contact wit 1 the coacting roller 20 and actuate the builder arm jointly with the action of the cam 37 on the roller 33. The rotation of the auxiliary cam 37 will cause the reciprocatory rocking of the arm and this will cause the guide rail to move up and down so as to wind the bunch onto the bobbin. During the upward movement of the arm 3 the pawl 23 will strike the fixed member 24 and will thus cause the turning of the ratchet wheel. As

the ratchet is turned the shaft 25. which is secured to it will be rotated and the movement of the screw 26 will cause a movement of the plate 2'? so as to move the stop pin-36 from the. position shown in Fig. 9 toward that shown in Fig. 10. This will permitthe lower end of the link bell crank lever to move from the position shown in Fig. 9 toward that shown in Fig. 10. It will be understood that this move ment is very:slight for each up and down movement of the arm. On the upward movement of the arm, the plates 38 and 3S,

the pawl 23 which is carried by the former, and the pin 39 which is carried by the lat ter, will resume their original positions because of the fact that the end 38 of the plate 38 together witlithe extension of the plate 38, overbalance the pawl and pin' end of these plates, thereby causing them to ascend until the pin 39 strikes the arm 3. In the next forward movement, the pawl'23 will the link 35 which is connectcd'to the bell crank lever by the turn bucklecoiinection is gradually assuming a verticalposition d'uring the progressive movement ot'tlie pin36. The link 35 finally gets the path of the pin 89 so that the'latter on its return by the weighted end of the plate does not reach its normal position, but is now stopped'by the This prevents thepawl 23 from riding over as many teeth as it would at the beginning of the operation, and henceshortens the angle through which the 'atchet wheel is rotated. The auxiliary cam 37 is now out of commission because the cam roller 33 has been lowered'past the point of engagement with the cam 37. This allows the large cam 19 to have full control of the stroke of the arm 3.

the arm 3 will now be a maximum, thatis to say, thestroke will'no'w conform to the requirement for winc'ling the thread on the bobbin, the bunch'having been made. While the cams 19 and 37' are working conjointly to cause the reciprocation of the arm during the making-of the bunch, a short stroke is produced, but when the cam 19 takes full control a long, stroke is produced. Now it is essential that the rotation of the shaft 25 which is caused as stated by the engagement of the pawl :23 with the fixed member 24-, shall be substantially the same during each stroke whether the stroke be short or long for the reason that the building of the thread on the bobbin must be uniform. It will therefore be seen that when the link35 comes into engagement with the pin 39 it will stop the return movement of the pawl at such a point that subsequent .long' strokes will move the pawl substantially throughthe same are as it is movedby the short stroke when the link 35 is out'of the way of the pin so as to permit it to have areturn movement until the pin engages the arm This feature I regard as one of the most important features of my invention, be,

went'ion lies not merely in providing an anar- -to automatically continue siiCI toiitrOl iv 'ile 't-rol mechanism out of operative-e1 beeir concluded \Vlien 'thebolibin been wound the auxiliary controli Since the large cam is greater in dimension, the throw or stroke of cause it the automatic regulation of the number of pick taken during each reciprocatory movement.
