2 Claims. (Cl. 24226.1)

This invention relates to mechanism for winding yarn and building yarn packages on bobbins or other similar yarn carriers.

It is the general object of the invention to provide improved builder mechanism which is readily adaptable to building bobbins of several-different types, such as standard warp wind, reverse warp wind, modified and combination warp wind, and filling wind. This invention also involves provision for effecting straight-line motion of certain essential parts and for avoiding motion of said parts in an are or segmental curve.

A further object of the invention is to provide means to maintain uniform tension on the ring rail lifting devices.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings, in which- Fig. l is a front elevation, partly in section, of a portion of a spinning frame embodying the present invention;

Fig. 2 is a transverse sectional elevation, taken along the line 2-2 of Fig. 1;

Fig. 2a is a detail front section, taken along the line 2a--2a in Fig. 3;

Fig. 3 is an end elevation taken from the head end of the machine, with the end cover panel removed, and

looking in the direction of arrow 3 in Fig. 1;

Fig. 4 is a partial end view similar to Fig. 3 but with certain parts in position to produce a different type of bobbin wind;

Fig. 5 is a plan view of a unit marked A in Fig. 3, and looking in the direction of the arrow 5 in Fig. 3;

Fig. 6 is a plan view, partly in section, of a unit marked B in Fig. 3, and looking in the direction of the arrow 6 in Fig. 3;

Fig. 7 is a rear elevation of a unit marked C in Fig. 3, and looking in the direction of the arrow 7 in Fig. 3;

Fig. 8 shows a modified type of pulley to be used with the mechanism of the unit C; and

Figs. 9 to 13 inclusive show bobbins with the different types of bobbin wind which can be produced by this builder mechanism.

Referring to the drawings, Figs. 1 and 2 show parts of a spinning frame comprising a head end frame member 10 (Fig. 1), an intermediate frame member 11, and an upper frame member or top girt 12 which is mounted on the upper ends of fixed posts 13. Roller beams 14 are mounted on the top girts 12 and support the usual drawing rolls '(not shown). A fixed rail 15 extends along each side of the frame and supports spindles 16 which are driven by tapes in the usual manner.

Rings R (Fig. 2) are mounted on ring rails 17, which are secured by brackets 18 to supports 19 slidable on the posts 13. These supports are moved vertically on the posts 13 by chains or cables 20 which pass over loose guide pulleys 21 (Fig. 2a) on cross shafts '22 mounted in the top girt 12. v i

The cables 20 are attached to connecting rods 23 (Fig. 2a) which are connected by chain or cables 24 to pulleys 25 fixed to a shaft 26 which is operatively connected to the builder mechanism to be hereinafter described. The cables 24 are attached to the pulleys 25 at 27 and pass upward and over guide pulleys loosely mounted on a shaft 28. The shafts 26 and 28 are mounted in bearings in a bracket 29 (Fig. 1) which is secured by bolts 30 to the frame member 10.

The yarns Y (Fig. 2) are led to the rings R through yarn guides 35, and the ballooning of the yarn is preferably controlled for each spindle by upper and lower antiballoon rings 36 and 37. The parts 35, 36 and 37 are mounted in panels 38 which are secured to verticallyslidable cross-members 39. Each member 39 is connected to chains or cables 40 (Fig. 2) which pass over loose guide pulleys 41 (Fig. 1) on the cross shaft 22 and which are connected by rods 42 and chains or cables 43 to pulleys 44 which are fixed 'to the shaft 28.

The vertical movements of the cross members 39 are simultaneous with the vertical movements of the ring rails 17 but are of less extent, as will be now described.

Referring to Fig. 3, the shafts 26 and 28 are supported in bearings 29 in the bracket 29. An outboard bearing 46 (Fig. 3) is also provided for the shaft 26. The cables 43 are attached at 43 to pulleys 44 which are fixed to the shaft 28. The cables 24 (Fig. 2a) pass over pulleys 47 loose on the shaft 28 and are attached at 27 to the pulleys 25 which are fixed to the shaft 26.

A pulley 50 (Fig. 3) is secured to shaft 26 and a pulley 51 is secured to shaft 28, and these two pulleys are connected by a chain or cable 52. The pulley 50 is of smaller diameter than pulley 51.

If shaft .26 is now oscillated, it will act through the pulleys 25, cables 24, connecting rods 23, and cables 20 to move the supports 19 up and down on the posts 13 and to thereby cause the ring rails 17 to traverse the yarns Y and build up the desired bobbin contour.

' As the shaft 28 is connected to the shaft 26 by the cable 52, the shaft 28 also will be oscillated and will act through the pulleys 44 (Fig. 1), cables 43, connecting rods 42 and cables 40 to move the cross members 39 upand-down on the posts 13'. The vertical movements of the guides 35 (Fig. 2) and the anti-balloon rings 36 and 37 will thus be simultaneous with the movements of the ring rails but over a shorter range, due to the difference in diameter of the pulleys 50 and 51.

The builder cam unit A (Figs. 3 and 5) consists of a cam shaft 55. (Fig. 5) which is rotatably supported in bearings of a bracket 56 secured by bolts 57 to the frame member 10. A gear 58 has a hub portion 59 secured to the shaft 55 and a cam 60 is fixed to the hub portion 59. The cam shaft 55 is rotated by the gear 58, which is driven from any convenient source of power.

bracket 29 and holds the housing from rotation. The

shaft 55 (Fig. 5) extends loosely into the'hub 63 of a chain sprocket 64. A pawl-and-ratchet feed mechanism within the housing 61 is operated by the rotated'shaft 55 and intermittently advances the sprocket 64.

The housing 61 (Fig. 3) is provided with an index plate 65 having an arcuate slot 66. A studextends through the slot 66 and is associated with the pawl-and-ratchet mechanism. The stud carries an indicator or index finger 67 which may be clamped to the index plate 65 by a screw 68.

Upon rotation of the cam shaft 55, the pawl-andratchet mechanism imparts an intermittent angular move- Patented May 2, 1961 3v ment to the chain sprocket 64. The amount of angular movement or pick given to the sprocket 64 is determined by manual adjustment of the indicator 67 on the index plate 65. I

The hub 63 (Fig. 3) has a small axial opening 69 and a slot 70 to receive a crank for a purpose to be described. Projecting from the housing 61 (Figs. 3 and is a stud 71 on which is mounted an idler chain sprocket 72.

The unit B (Figs. 3 and 6) involves the axial builder lever and certain associated parts and comprises a lever 75 (Fig. 6) provided with a forked hub 76 which is loosely mounted on bushings 77 secured in bearing portions 78 of a bracket 79 which is fastened by bolts 80 to the frame end 10.

A roll or cam follower 81 (Fig. 6) is mounted on a stud 82 in the lever 75. Another roll 83 is rotatable on a stud 84 carried by a slide 85, and the slide 85 is threaded to receive a screw 86 which is supported in a bearing 87 in the lever 75.

The bearing portions 78 of the bracket 79 support a shaft 88 on which two bevel gears 89 and 90 are secured. Either one of these gears may be made to engage a bevel gear 91 which is pinned to the screw 86. Secured to the shaft 88 is a chain sprocket 92 which is connected with the sprocket 64 (Fig. 5) by a chain 93 (Fig. 3).

Any movement given to the sprocket 64 by the pick mechanism in the housing 61 will be transmitted by the chain 93 to the shaft 88 and to the screw 86, thereby moving the slide 85 and roll 83 along the lever 75. An adjustable stop 94 (Fig. 3) secured on the lever 75 by a screw 95 limits the travel of the slide 85.

The unit C (Figs. 3 and 7) relates to operating connections between the builder lever 75 and the ring rails 17. The unit C comprises an arm 100 (Fig. 7) pivoted on a stud 101 in a carriage 102. The carriage 102 has rolls 103 which engage parallel edges of bars 104 (Fig. 3) fixed in a standard 105 which is secured by bolts 106 to the frame end 10.

The arm 100 (Fig. 3) has an adjustable stop 107 cugageable with a fixed surface of the carriage 102. A pulley 109 is rotatable on a stud 108 in the carriage 102. A stud 110 in the upper end of the standard 105 supports a pulley 111 and unitary worm gear 112. The gear 112 engages a worm 113 on a shaft 114 which is supported in bearings 115 (Fig. 7) in the standard 105. A sprocket 116 is pinned to the shaft 114. One end of a chain or cable 117 is attached at 118 to the pulley 111. The chain 117 then passes downward and around the loose pulley 109. The return end of the cable is attached at 119 to a pulley 120 which is secured to the shaft 26.

When looking at Figs. 1 and 2, it will be seen that the weight of the cross members 39 (Fig. 2) and their associated parts will, if not restrained, pull the connecting rods 42 (Fig. 1) and cables 43 to the right, and cause the shaft 28 to be turned in a clockwise direction.

Also, the weight of the supports 19 and ring nails 17 will tend to pull the connecting rods 23 (Fig. 2a) and cables 24 to the right and to cause the shaft 26 to be turned in a clockwise direction. The weight of the car riage 102 (Fig. 3) and arm 100 further adds to the force that tends to swing the shaft 26 clockwise (Fig. l) and to oppose effective action of the cam 60 in moving the cross members 39 and supports 19 axially on the posts 13.

To offset these combined clockwise forces, a counterforce is applied to the shaft 26. This consists of a bar 125 (Fig. 1) located below the cross shafts 22 and supported at several places along the frame. A chain or cable 126 is attached at 127 to the end of the bar 125, and this cable passes over a guide pulley 128 pivoted in an extension 129 of the bracket 29. The lower end of the cable 126 is attached at 130 (Fig. l) to a cam 131 which is secured to the shaft 26.

A series of blocks 132 are pinned to the bar 125 and are provided with eye-bolts 133 to which are connected 4 one end of certain tension springs 134 anchored on the fixed cross shafts 22.

The counterforce of the springs 134 is greater than the combined forces exerted by or through the parts 19, 39 and 102, and this counterforce swings the shaft 26 anticlockwise (Fig. l), and the cable 117 pulls the carriage 102 upward until the cam follower 81 engages the cam 60 (Fig. 3).

As shaft 28 is connected by the cable 52 to the shaft 26, shaft 28 will also be affected by the counterforce, so that all the cables from the shafts 28 and 26 to the cross members 39 and supports 19 will be under tension.

When the machine is in operation, the cam 60 will be elfective through the lever 75 and arm to move the carriage 102 axially on the bars 104, and the cable 117 and springs 134 will rock the shaft 26 first in one direction and then in the other. The net pull of the springs 134 on the bar and shaft 26 will be continually changing. But it is desirable that the counterforce applied to the shaft 26 be maintained substantially uniform. This is accomplished by attaching the chain or cable 126 to the profile cam 131 as shown in Fig. 1.

When the winding of the bobbins is completed, the cross members 39 (Fig. 2) must be first moved to bring the guides 35, 36, and 37 to dofiing position. A collar (Fig. 3) is fixed to the shaft 28 and has an offset portion or lug 141 which lies in the path of a lug or dog 142 in the sides of a worm gear 143 which is freely mounted on the shaft 28.

A cross shaft 144 is mounted in bearings in the bracket 29 below the shaft 28 and gear 143. A worm 145 on the shaft 144 engages the gear 143. The end of the shaft 144 has a slot 146 to receive a hand crank. To raise the cross members 39, the operator manually turns the shaft 144 by the hand crank until the lug 142 on the gear 143 contacts the lug 141 on the collar 140. The

shaft 28 may then be turned anti-clockwise the required amount. As the shaft 28 is thus moved anti-clockwise. the cable 52 connecting the shaft 28 to the shaft 26 will be slackened.

The shaft 26 has a similar gearing connection to a shaft 150, and the operator can turn the shaft 26 clockwise (Fig. l) by means of a hand crank on the shaft 150 and can thus lower the ring rails 17 to a position slightly below their lowest operating position.

After the full bobbins have been removed from the spindles and have been replaced by fresh bobbins, the operator uses the hand crank to turn the gear 143 in the opposite direction, thus disconnecting the gear 143 from the collar 140, and allowing the yarn guides 35, 36 and 37 to return to their operative positions. This also takes up any slack in the cable 52. To bring the ring rails 17 up into their operating zone, the operator then uses the hand crank on the shaft 150 to return the shaft 26 to initial operative position.

Operation To produce a standard warp wind as shown in Fig. 9, the bevel gear 90 (Fig. 6) is engaged with the gear 91 on the screw 86. The slide 85 is then brought against the stop 94 as in Fig. 3. The tread of the lever 100 on which the roll 83 travels is adjusted by the screw 107 to stand horizontally or at a right angle to the bars 104.

The cam 60 oscillates the lever 75 and causes the roll 83 to reciprocate the carriage 102 along the upright bars 104, and the cable 117 and springs 134 will coact to oscillate the shaft 26 through which the ring rails and yarn guides are vertically reciprocated to lay the yarn on the bobbins.

As the winding progresses, the pick mechanism in the unit A will advance the sprocket 64 in small increments and thus cause the chain 93 and gears 90 and 91 to intermittently rotate the screw 86 and thereby cause the slide 84 to move to the left in Fig. 3. The roll 83 is thus moved in small increments along the tread of the lever 100 and so gradually decreases or shortens the traverse of th: carriage 102 and the traverse of the windings on the bobbins.

When the bobbins are full, the cross members 39 and slides 19 are returned to starting positions by hand operation of the cross shafts 144 and 150, as above described. But before returning the ring rails 17 to their operating zone, the operator must insert a hand crank into the slot 70 in the hub 63 of the pick mechanism in unit A and turn the screw 86 to return the slide 85 to again engage the stop 94. When the ring rails are then raised to their operating zone, the builder mechanism is ready to commence winding another set of bobbins of the type shown in Fig. 9.

To produce the reverse warp wind shown in Fig. 10, the gear 89 (Fig. 6) is engaged with the gear 91 on the screw 86, and the stop 94 is moved from its position shown in Fig. 3 to a position at the other end of the screw 86, where the stop 94 may be again attached to the lever 75 by inserting the clamping screw 95 into the tapped hole 95 As the winding progresses, the pick mechanism will intermittently rotate the screw 86 which will now move the slide 85 and roll 83 to the right in Fig. 3, and so gradually increase the traverse of the carriage 192 and the traverse of the windings on each bobbin. When the bobbins are full, the procedure for operating the shafts 144 and 150 and for resetting the slide 85 against the stop 94 is the same as that described for the standard warp wind of Fig. 9.

In Fig. 9, the tapered end portions are shown as equal, but unequal tapered portions may be desired. To change the relation of these tapered portions, it is only necessary to adjust the arm 100 (Fig. 3) on its pivot 101 by turning the screw 107 to cause the tread of the arm 100 to be shifted to a selected and different angle relative to carriage 102.

It may, also be desirable that the bottom portion of the bobbin be rounded as shown in Fig. 11 instead of presenting a straight conical surface. This rounded effect may be produced by providing the pulley 120 (Fig. 8) with an enlargement 120a.

To produce the filling wind of Fig. 12, the following procedure is followed:

The strap 62 (Fig. 3) is detached from the bracket 29 and the housing 61 (Fig. 5) is removed from the shaft 55. The warp cam 60 (Fig. 3) is then removed and replaced by the filling cam 160 shown in Fig. 4. The housing 61 is then put back on the shaft 55 and the pick mechanism is connected by the chain 93 with the sprocket 116 on the shaft 114. The strap 62 is then re-attached to the bracket 29.

Then the slide 85 is moved along the lever 75 by manually turning the screw 86. The roll 83 may thus be I to turn the shaft 114. The associated worm 113 (Fig. 7)

positioned on the lever 101) to produce the short traverses required in this type of wind. When the setting of the roll 83 is determined, the screw 86 is then locked to prevent movement of the slide 85 on the lever 75. This locking result may be conveniently attained by engaging both bevel gears 89 and 90 (Fig. 6) with the gear 91. The builder mechanism is now ready to provide the filling wind shown in Fig. 12.

As the winding progresses, the pick mechanism will now intermittently act through the sprockets 64 and 116 will turn the gear 112 and pulley 111 clockwise as viewed in Fig. 7, so that the cable 117 is intermittently let off from the pulley 111 until the length of the bobbin is completed.

When the bobbins are completed, the same procedure is followed as that described for the bobbins in Figs. 9 and 10, except that the slide remains locked and the pulley 111 is manually returned to its initial or starting position.

The combination warp wind shown in Fig. 13 is produced in the same manner as the bobbin in Fig. 12, the only difference being that the traverses in Fig. 13 are longer than the traverses in Fig. 12, so that the warp cam 60 is used for the bobbin in Fig. 13 instead of the filling cam 160. The slide 85 remains locked to provide fixed traverse and the cable 117 is let off to shift the traverse toward the tip of the bobbin.

Having thus described by improved builder mechanism and its adaptability to produce a wide range of bobbin windings, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a textile machine having vertically-movable rings and ring rails, in combination, a rotated builder earn, a builder lever mounted on a fixed axis and engaged by said cam, ring-rail-moving devices including a reciprocated carriage, an arm adjustably secured on said carriage and having a tread surface, a roll to engage said tread surface, a roll-supporting block mounted on said builder lever, and a rotated screw, mounted on said builder lever,

which engages and shifts said roll block lengthwise of said builder lever to change the traverse of the yarn.

2. In a textile machine having vertically movable rings and ring rails, in combination, the builder means to produce a builder motion, a builder lever mounted on a fixed axis and engaged by the builder means, a ring rail moving device including a reciprocable carriage, an arm on the carriage having a tread surface, means on the lever engaging the tread surface and being adapted to move laterally over said surface, and a rotated screw, mounted on said builder lever, which engages and shifts said tread surface-engaging means lengthwise of said builder lever to change the traverse of the yarn.
