6' Claims.

Theobject of my invention is to provide a novel machine for winding spools of thread having single tapered ends, said machine comprising, generally, means whereby thread of varying sizes may be wound on a spool having a single tapered end, which spool and its laterally movable mandrel are mounted against longitudinal movement; means being provided for imparting a continuous endwise movement to the traverse mechanism in one direction as the spool is being wound.

My invention comprises, more specifically, a variable speed drive for continuously shifting the traverse mechanism endwise at the desired speed, according to the size of the thread being wound. I

My invention further comprises a suitable speed reduction unit for driving the traverse mechanism, manual means being employed for disconnecting the speed reduction unit from the traverse mechanism after the winding of the spool is completed, and means also being provided for automatically returning the traverse mechanism to its normal starting position when released from its speed reduction unit.

My invention still more specifically comprises a movable change speed reduction unit in which the final gear of the unit is normally in mesh with a longitudinally disposed rack carried by the traverse cam, said final gear being manually moved out of mesh with the rack after the winding of the spool has been completed, means being employed for automatically returning the final gear of the speed reduction unit into mesh with its rack when thespeed reduction unit is released reduction gear in its inoperative position.

The winding machine herein illustrated generally comprises a rotary traverse cam slidably interlocked with the rotary cam shaft 2 for endwise movement thereon. This traverse cam I reciprocates the traverse guide 3, said guide being carried by a guide bar 4 having a stud or roller 5 which travels in the cam groove 6 of the traverse cam I, said guide bar 4 having a reciproeating movement parallel to the spool mandrel l, on which mandrel is removably mounted the spool 8 having a single tapered end 9.

The spool mandrel has a rotary movement and also a lateral movement but is mounted against endwise movement, the means for accomplishing the rotary movement and the lateral movement of the mandrel being of the usual form and a general description thereof will only be included herein.

The spool mandrel l is journaled in a bracket is fast on aslide bar H. The'pulley l2 on the main drive shaft 53 is driven from any suitable source ofpower, not shown herein. A loose pulley M is mounted on the shaft l3 adjacent the drive pulley i2. A wide faced spur gear 55 is fast on the drive shaft is and it meshes with a spur gear iii rotatably mounted on the slide bar ,I I; This spur gear it has a bevel gear H which meshes with a bevel gear I 8 carried by the mandrel T. The cam shaft 2 is driven from the shaft [3 through the pulley E9, belt l$* and pulley'ii'fi, which pulley 25 is fast on a cross shaft 2 l which carries a bevel pinion 22 meshing with the bevel gear 23 fast on the cam shaft 2.

The mandrel l is yieldingly held at'the limit of its inward movement as, for instance, by, the usual weight 2 flexibly connected with the arm 25 of the tension device, which tension device is connected through the link 2:3 with the lever 26 which actuates the slide bar ll.

The rotary traverse cam l is yieldingly held at the limits of its endwise movement on the cam shaft 2, by means of a coil spring 2i interposed between the hub 28' of the traverse cam i and the hub 29 of the bevel gearifi.

The means whiclrI have shown for impart! inga continuous endwise movement, to the'ca'm shaft 8 in a direction against the tension of the spring 2? while the spool is being wound, is constructed arranged and operated as follows:

A longitudinally disposed rack 3% is carried by asleeve 3i which surrounds the rotary camshaft 2 and isslidably interlocked with the machine frame 3 2. The inner endof this'sleeve M is'connected to the hub 28 of the traverse cam l to move the cam endwise. In the present instance this sleeve 3i is provided with a head 33 seated within the hub 28, a plate 3% overlapping the head, which plate is secured to the end of the hub.

The change speed reduction unit has its casing 35 pivoted at 35 to the machine frame 32, to swing vertically into and out of its operative position. The final gear 3'! of this speed reduction unit projects through the casing 35 into mesh with the rack 39. A spring 38 extends between the machine frame and a lug 3% projects from the casing 35 and serves to hold the unit in its operative position, a stop 40 on the machine frame limiting the downward movement of the unit. A handle ll projects from the casing 35 in position to be used for rocking the unit upwardly to disconnect the final gear 3'5 from its raol: Bil when the winding of the spool has been completed.

The worm drive shaft 62 of the speed reduction unit may be adjusted laterally to bring its worm 33 into engagement with any one of a plurality of concentric rings of teeth Q4, 55 or 46 on the under face of the rotary disc ll.

This worm shaft 412 is rotatably mounted a casing member 38 which may be secured to the casing 35 in the several adjustments above re ferred to.

"The worm shaft 52 may be driven at difierent speeds from the cam shaft 2 by providing the cam shaft with a-stepped-down pulley 59 and the worm shaft 32 with a stepped-up pulley 5%, the two pulleys being connected by a belt 5i.

In operation: As the winding of the spool starts, the very slow endwise movement of the rotary traverse cam also starts in direction away from the free end of the spool and this slow endwise movement of the traverse cam continues until the spool is completely wound. This endwise movement of the rotary traverse cam compresses the spring 2?. The handle 45 of the change speed reduction unit is then grasped and the unit is rocked to move its final gear 31 out of mesh with the rack (it. As soon as the gear 3? is disconnected from the gear 36 the spring 27 will automatically return the rotary traverse cam to its normal starting position. It will be understood that as the spool is wound the'mandrel is automatically moved laterally, as is usual in this type of machine.

The variable speed drive for the speed reduction unit and the changeable speed for the reduction unit serve together to adjust endwise movement of the rotary traverse cam to the size of material being wound, between wide limits.

It is evident that various changes may be resorted to in the construction, form and arrangement oi the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the par- ,ticular embodiment herein shown and described.
