ATTACHMENT FOR SPEEDER STOP-MOTIONS.

Specification of Letters Patent.

Patented Apr. 1d, 191?.

To all whom iii-may concern:

Be it known that l, Eannns'r L. JACKSON, a citizen of the United States, residing at Columbus, in the county of Muscogee and State of Georgia, have invented certain new and useful Improvements in Attachments for Speeder Stop-Motions; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to attachments for Speeders and the like, and has for an object to provide means for cOnJinuing the action of the traverse and the bobbin-winding apparatus after the breaking of the cone belt and until the machinery has been brought to a stop by some form of automatic stop device.

A further object of the invention is to provide a device especially, though not eX- clusively, adapted for operation in conjunction with the stopping device disclosed in application Serial No. 728,174, filed October 28, 1912.

With the use of any form of automatic stop mechanism as disclosed in said applica tion orotherwise the momentum of the machine after the cone belt breaks causes the spinning and feeding apparatus to continue to move for a limited time, whereas the winding stops. This causes-a tangling of the thread. The use of the automatic stop device eliminates a large amount of such tang-ling, but even when used with an automatic stop device some tangling occurs which it is desirable to avoid.

The present invention embodies means for operating in conjunction with the cone drive normally out of gear and inoperative and adapted to be thrown into gear and operate only when the lower cone drops, taking up approximately the speed of the lower cone and continuing to operate the winding mechanism until the machine comes to a full stop.

A further object of the invention is to provide an automatic clutch arrangement adapted to be thrown into engagement by the dropping of the bottom cone, provided with shafts normally geared into the top cone shaft and into the winding drive shaft but driven normally independently from such shafts with the clutches out of engagement.

A further object of the invention is to provide such a connecting means having a plurality of speeds driven by separately intergearcd gearings, with means for shifting at each reciprocation of the cone rack.

With these and other objects in view the invention consists in certain novel features of construction, combination and arrangement of parts will be hereinafter more fully described and claimed.

In the drawings Figure 1 is a fragmentary conventional view of the cone mechanism with the improved attachmentconnected therewith.

Fig. 2 is a view of the clutch mechanism with one part of the housing removed.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2.

Like characters of reference designate corresponding parts throughout the several views.

The improved attachment which forms the subject-matter of this application is adapted to be associated with a speeder of the usual and ordinary type embodying a top cone 10 and bottom cone 11 as shown Fig. 1., the former being driven by its drive-shaft 12, and the latter driving the winding shaft 13 through any approved connecting means the belt 1%.. The bottom cone is driven from the top cone by the usual and ordinary cone belt 15 which in. turn is shifted by the cone rack 16. The foregoing mechanism is that found upon the usual and ordinary speeder and forms no part of the present invention.

At some conven ent point intermediate the cones the gear housing 17 is secured, having a shaft 18 carrying a bevel gear 19 intergeared with the bevel gear 20 on the top cone shaft 12.

The housing 17 also journals a shaft'21 caryin a bevel gear 22 inter 'eared with the bevel gear 23 on the winding drive-shaft 13.

Under normal conditions the shaft 18 is driven from the shaft 12 and the shaft 21 is driven from the shaft 13. with no interengagement within the housing 17 preventing the free and independent rotation of such shafts.

Within the housing, however, the shaft 18 is provided with a clutch member 24 splined thereon, and movable longitudinally thereof into engagement with the clutch face 25 integrally or rigidly connected with the gear 26 mounted normally free to rotate upon the shaft 18. The shaft 21 also carries a similar clutch member 27 splined and slidably movable thereon, adapted to interengage with the clutch face 28 of the gear 29. The gear 29, like the gear 26, is free to rotate upon the shaft 21 and interengages with a gear 30 also normally free to rotate upon the shaft 18. The gear 26 intergears with the gear 31, likewise normally free to rotate upon the shaft 21.

The clutch 24 is actuated by a yoke 32 carried by the lever 33, and the clutch 27 is actuated by a like yoke 34 actuated by the lever 35. To control the lovers 33 and 35 a lever 36 is provided pivotally connected with the housing 17 at 37 as shown more particularly at Figs. 1 and 3, and having pivotal. connection with such levers 33 and 35 at 38. It is obvious that when the lever 36 is moved in the direction of the arrow shown at Fig. 3 the levers 33 and 35 will be actuated to throw the clutch members 24 and 27 into engagement with the clutch faces 25 and 28 whereby the gears 26 and 29 will rotate with the shafts 18 and 21 respectively. The lever 36 is actuated in any approved manner when the bottom cone drops as by providing an arm 39 carrying a roller 40 which, when the cone drops, engages the cam 41 to move the lever 36 in the direction indicated by the arrow. When, however, the cone drops it is the result of the breaking of the belt 15, and shaft 13 ceases to be operated from the lower cone 11. Provision is therefore made for driving the shaft 21 from the shaft 18 when the clutches 24 and 27 are thrown into engagement. This engaging means is controlled from the cone rack 16 which is provided with an abutment 42 engaging a lever 43 pivotally connected with the housing in any approved manner as by the use of the arm 44 terminating in the stud 45 upon which is mounted the cam 46 rigidly connected to and oscillating with the lever 43. Below and engaging with the cam 46 is a plunger 47 slidably inserted through the brace 48 and pivotally connected with the walking beam 49 which is in turn pivotally connected with the housing 17 in any approved manner as by the link 50. A spring 51 is employed to normally hold the plunger 47 yieldingly in engagement with the periphery of the cam 46.

Connected with the walking beam 49 at its end opposite the plunger 47 is a rod 52 passing upwardly through the housing 17 and integral with or rigidly connected to the sliding frame 53.

The sliding frame 53 carries yokes 54 and 55 engaging respectively the clutch members 56 and 57 which are respectively splined upon and movable longitudinally of the shafts 18 and 21. The clutch members 56 and 57 are respectively adapted to engage with the clutch faces 58 and 59 integral with or rigidly connected to the gears 30 and 31 respectively. The cam 46 is provided with springs 60 and 61 which are positioned to engage against the plunger 47 when the abutment 42 passes over the end of the lever.

43 and to throw such lever back into position for engagement by the abutment when the cone rack moves in the opposite direction as indicated more particularly at Fig. 4.

It will therefore be apparent that as the cone rack 16 reciprocates, the lever 43 is oscillated upon its pivot 45, and through the connection above described causes the sliding frame 53 and the clutch members 56 and 57 to reciprocate to bring such clutch mem bers 56 and 57 alternately into engagement with the clutch faces 58 and 59. As shown at Fig. 2, all of the clutches are in neutral position, but at each reciprocation of the cone rack the speed change clutches are caused to engage, but as the drive clutches are out of engagement the only result is a difference in the rotation of the several gears which, however, is not transmitted to the shaft 21. The position of the abutment 42 upon the cone rack 16 is such that the speed is changed when the cone belt 15 is substantially at the middle of its travel, and the connecting gearing is such that when the drive clutches are'thrown into engagement the change speed clutches are in position to drive the shaft 21 faster or slower according to the position of the sliding frame 53 which is in turn controlled by the position of the cone belt 15. If, therefore, the cone belt breaks when between the middle and larger end of the upper cone the clutch mechanism is thrown into'engagement upon high speed, whereas if the cone belt breaks when the belt is between the middle and smaller end of the drive cone the clutch mechanism is thrown into engagement at low speed. The speeds are intended to be so arranged that when the drive clutches are thrown into engagement on high speed the shaft 21 will be driven substantially at the speed the lower cone is driven when the belt is half-way between the center point of the drive cone and its larger end; that is to say, at substantially one-third its travel from the larger to the smaller end, whereas ifthe cone belt breaks when the cone belt is between the middle and the smaller end of the drive cone, the low speed rotates the shaft 13 at substantially the speed of rotation when the belt is two-thirds its travel from the larger to the smaller end of the drive or upper cone. While the drive thus provided varies somewhat from the actual speed at which the shaft 13 would be driven by the cone drive, it corresponds sufficiently thereto to prevent snarling of the thread due to complete stopping of the winding apparatus, such winding apparatus being continued in motion at a speed nearly the equivalent of the cone drive until the whole machine can be brought to a stop by the automatic stop. In explanation of the gearing shown at Fig. 2, it may be pointed out that when the drive clutches are thrown into position the gears 26 and 29 are rigidly connected with the shafts 18 and 21 respectively. When the gears are in position for slow drive the sliding frame 53 is down and the clutch 56 in engagement with the clutch 58, but the clutch 57 is out of engagement with the clutch face The interengagement of the clutch 56 with the clutch 58 causes the gear 30 to rotate also with the shaft 18 and to drive the ear 29 which, by reason of the engagement of the clutch 27 with the clutch 28, drives the shaft 21, but the gear 30 being smaller than the gear 29 the shaft 21 is driven slower than the shaft 18. Suchdriving is permitted from the fact that the gear 31 is not now connected with the shaft 21 but is free to rotate thereon and although the gear 26 rotates with the shaft 18 it has no effect upon the gear 31 except to rotate it freely upon the shaft.

When the high speed is to be applied, the clutch 57 engages the clutch face 59, the clutch 56 58 being now out of engagement. The gear 26 being driven with the shaft 18 drives the gear 31 which, by reason of the clutch engagement, is rigidly connected with the shaft 21 so that the shaft 21 is driven from the large gear 26 upon the drive shaft, the small gear 31 upon the driven shaft, thereby rotating the shaft 21 to higher speed, this being permitted. from the fact that the gear is free to rotate with the shaft 21 since the gear 30 is free to rotate on shaft 18. As the sliding frame reciprocates at each reciprocation of the cone rack, it follows that the gear is in position to pick up at fast or slow speed according to the position of the cone belt whenever such cone belt breaks, and owing to the fact that the machinery is all in motion there is comparatively little strain upon the pick-up owing to such breakage.

I claim:

1. The combination with a speeder involving a cone drive, of clutch mechanism con nected ,with the opposite sides of such drive, means to shift the clutch mechanism from high to low speed at each reciprocation of the cone belt, and means to throw the clutch mechanism into operation when the lower cone drops.

2. The combination with a speeder involving a cone drive, of shafts intergeared with the upper and lower cone drive mechanism, gears carried by the shafts normally free to rotate upon such shafts, speed change mechanism, means to actuate the speed change mechanism from the reciprocation of the cone rack, clutches adapted to connect the gearing with the shafts, and means actuated when the lower cone drops to throw such last-named clutches into engagement.

8. The combination with a speeder involving a cone drive, of shafts intergeared with the top cone driving mechanism and with the mechanism driven by the bottom cone respectively, intergeared gearing carried by the shafts and normally free to rotate thereon, speed changing mechanism actuated from the cone rack, clutches adapted to connect the gearing w'th the shafts, a lever adapted to actuate the clutches, and means carried by the lower cone for actuating the lever when the cone drops.

l. The combination with a speeder involving a cone drive, of normally inactive gearing interposed between the cones, means to change the speed connection to correspond approximately with the speed change of the cone drive, and means to throw the normally inactive gearing into action to drive the mechanism when the cone belt breaks.

In testimony whereof I affix my signature.
