CHEN-ILLE UNTWISTING- AND WINDING MACHINE.

LoUIs TIscH, a citizen of the United States,

and a resident of Elizabeth, in thecounty of Union and State of New Jersey, have invented a new and Improved Chenille Untwisting and Winding Machine, of which the following is a full, clear, and exact description.

' This invention relates to machines for untwisting chenille as it leaves the chenille forming machines, an object of the lnvent on being to provide an improved construction which will automatically untwist the chenille continuously.

Another object of the invention is to provide a machine timed to operate in proper step with the machine which forms the cluenille so that it may produce an untwistlng action as fast as the chenille is-manufactured, the arrangement being such that the mechanism for untwisting the chenille is comparatively small and, consequently, -requires but little space to properly untwist great lengths of chenille.

A still further object of the invention is to' Referring to the accompanying drawings by numerals, 1 indicates a base of any desired character provided with a frame 2 having suitable bearings to receive certain shafts hereinafter fully described.

. Heretofore, in the manufacture of chenille as it comes'from the. machine, it is moved over a table or platform where the full length of the chenille, as for instance, twenty or thirty yards, usually six strands are! manufactured at one time and moved simultaneously over a table. However, this re.- quires a large amount of space in the factory and in addition, after the chenille has been laid out lengthwise on the table, it has to be untwisted. Each strand of chenille is taken manually andconnected up with the Well-known apparatus which is manually rotwtsd an thu the various strips are manu- Speciflcation of Letters Patent.

ally untwisted. This operation not only requires a large amount of factory space, but 1s expensive by reason of the use of an extra number of assistants for the untwisting operation.

In the present invention the various strips or cords of chenille are fed directly into the untwisting machine shown in the drawing and are'untwisted at the same rate that they are manufactured, and as they are untwisted, they are wound on a drum 3. The drum 3 may be of any desired size and is slidably mounted upon a shaft 6. The shaft is carried by a bracket 7 bolted or otherwise rigidly secured to a sleeve 40 on which is rigidly mounted a pulley 19.

A section 8 of bracket 7 is hinged at 9, and a suitable catch 10 is provided at the upper end of section 8 so that the shaft 6 may be disengaged from bracket 7 at one end in order to allow the spool or drum 3 to be slid off of said shaft and a new one substituted at any time. The spool 3 is connected with a driving disk 11 by any desired means, as for instance, connecting screw 12 which rigidly clamps the disk 11 to the spool, but which may be unscrewed readily at any time.

A spring 13 is provided and positioned to act continually against the disk 11 forcing the same in acertain direction whereby the friction surface 14 of the disk Will be pressed against the cone 15. During the winding of the chenille on the spool 3, the cone 15 will be moved gradually away from shaft 6 and consequently, the spool 3 will be moved longitudinally of shaft 6 under the action of spring 13. This gradual movement of the cone 15 away from shaft 6 will continue until it reaches the position shown in Fig. 1 and then will automaticall move back unless prevented by stopping t e machine or from some other cause. As the surface 14: 'engages the conie 15 near its greatest periphery, the speed of spool 3 will be greatest and said speed will decrease relative to the movement of cone 15 as said cone moves to the position shown in Fig. 1. The parts are set so that this movement of cone 15 will be in proportion to the matter wound on spool 3. The speed of the spool 3 is slowest when the parts are arranged as shown in Fig. 1 but when the surface 14 of wheel 11 engages the cone 15 near the periphery, the speed of the spool 3 will be greatest in respect to cone 15. This will ause the chenille to be fed. in u stan i y equal quantities over the entire spool and at approximately the proper speed according to the speed'of the other parts.

The cone 15 is rigidl secured in any desired manner with a hollow shaft 16 earned by frame 2, said hollow shaft receiving the chenille 17 from the point where 1t s manufactured and guiding the same as 1t moves toward the spool 3. Inorder that the spool 3 and the dlsk 11 shall rotate, shaft 16 1s held stationary by means of the oppositely positioned pins 21 extending into the slots 22 of the bifurcated end 23 of lever 24. The .lever 24 is swung back and forth as hereinafter fully described and, consequently, reciprocates shaft '16 and cone 15 without rotating the same. In order that the chenille shall be untwisted, power is transmitted through pulley 19, through the cable or belt 18 from the chenille manufacturing machine or other suitable power, whereby the sleeve 40 is rotated, and, consequently, the bracket 7, disk 11, spool 3, and associated parts. This will cause the disk 11 to roll around the cone 15 and produce a rotary movement of the disk 11 and drum 3 for windin the chenille on the drum 3 as it is untwiste Thelever 24 is pivotally mounted on shaft 25 and has a laterally extending shaft or stud 27 projecting from the lower end thereof on which a link 28 is pivotally mounted. The link at its opposite end is pivotally connected at 29 to a disk 30 which is connected with a worm 31'by a suitable. shaft 32. In this way as the worm wheel 31 rotates, the lever 24 will be gradually swung in and out, moving the cone 15 toward and from shaft 6. The worm wheel 31 meshes continually with the worm 33 secured to the shaft 34.

The shaft is journaled in a suitable hearing box in frame 2 and carries a beveled gear.35 at one end. The gear 35 meshes with pinion 36 which is rigidly secured to shaft 37 carrying a sprocket wheel 38. This sprocket wheel receives power from a chain 39. The sprocket chain 39 preferably receives power from the same sourceas belt 18 and is timed to move with said belt so that the back and forth movement of cone 15 will be in proportion to its rotation, whereby the plane of. rotation of the bracket, a beveled disk connected with said drum and engaging said cone whereby as the bracket and disk are rotated, said disk will frictionally engage the cone and be rotated in a plane at right angles to the rotation of the bracket and thereby rotate said drum, and means causing said disk to press against said cone.

An untwisting machine for chenille comprising a drum, means for guiding chenille to the drum, a bracket carried bysaid drum, power mechanism. for rotating said bracket in one plane, said drum being mounted on said bracket to rotate on its own axis in a plane at right angles to the. firstmentioned plane, a friction disk carried by the bracket and engaging said drum for the purpose of rotating the drum on its own axis, a non-rotatable cone engaging said disk in such manner that as the disk is rotated with the bracket, the disk is also turned on its ownaxis, said drum turning on its own axis for the purpose of winding the chenille 'upon the drum, and mechanism for moving said cone toward and from said drum during the rotation of said drum in order to vary the speed of rotation of said drum."

4. A device of the character described comprising a drum upon which chenille is to be wound, a driving mechanism connected with said drum for the double purpose of turning said drum on its own axis and of spinning the drum in a plane at right angles to its own axis in order to untwistthe chenille as the latter is wound upon the upon the drum so as to distribute the chenille evenly upon the drum.

5. A' chenille untwisting machine comprising a drum, a tube for guiding chenille to the drum, means for conferring upon said drum a reciprocating motion relatively to said tube, a friction cone rigidly secured to said tube, means for preventing said tube and said friction drum from rotating, a bracket for supporting said drum, driving means for rotating said bracket, a disk connected With said drum and bearing against said friction cone for the purpose of turning the disk and the drum upon their own axes When said bracket is rotated, and spring mechanism connected with said disk for causing said disk to engage said friction cone independently of the position of said friction cone.

6.
