T0 aZZ whom it may concern:

Be it known that I, THORVALD HANSEN residing in Everett, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Thread -Winding Machines, of which the following description, in con specification, like letters and figures on the drawings representing like parts.

This invention relates to a winding machine or apparatus especially designed and adapted for winding thread, yarn, or like material upon a cop or cylinder, and has for its object to provide a simple, efficient, and rapid machine forthe purpose specified.

In accordance with this invention the machine is provided with a rotatable cop or cylinder upon which the thread is wound and with a rotary thread-guide which cooperates with the said cop and effects a traverse of the thread longitudinally of the cop in opposite directions to thereby wind or lay the thread thereon in successive layers. The rotary thread-guide is driven, preferably, by a mechanism, as will be described, which preferably includes a frictional speed-changing device, as will be described, whereby the speed of rotation of the rotary thread-guide may be varied according to the size of the thread to be wound. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a front elevation of a winding apparatus embodying this invention, the cop being shown in section; Fig. 2, a top or plan view of the apparatus shown in Fig. 1; Fig. 3, a'transverse section of the machine shown left; Fig. i, an end elevation of the machine shown in Fig. 1, looking toward the right; Fig. 5, a sectional detail to be referred to, the section being taken on the line 5 5, Fig. l; and Fig. 6, a sectional detail, to be referred to, on the line 6 6, Fig. 2, looking toward the left. Referring to Figs. 1 and 2, A represents a cop tube or cylinder upon which the thread is Wound, the said tube or cylinder being of any suitable or desired construction and which in the present instance is represented at the longitudinally-split end of a shaft a,

sum No. 565,835. (No model.)

the split end of the said shaft being made hollow for the reception of a threaded rod or expander a by means of which the end of the shaft a may be expanded and contracted to fit cop-tubes of varying diameters.

. The cop-shaft a is driven directly from a main shaft a as herein shown, by means of a gear a fast on the said cop-shaft, meshing with a gear a fast on the main shaft 0. the said cop-shaft being capable of an oscillatory movement, for a purpose as will be described, by means of'a rocking frame or arm a fast on a rock-shaft a and provided at its upper end with a bearing sleeve or hub of, through which the cop-shaft is extended.

Y In'accordance with this invention the copholder 01., secured to or forming part of the cop-shaft a, has cooperating with it a rotary thread-guide, preferably of the construction herein shown, and consisting of a cylinder or drum a fast on a shaft e and provided on its periphery with a cam-slot e into which the thread or other cord is placed and by which it isguided and carried longitudinally along the cop-tube in opposite directions to lay the thread on the said tube in successive layers. In the present instance the rotary thread-guide a is made fast on the shaft a by a set-screw (See Fig. 2.) The shaft e is driven from the main shaft a by gearing, as will now be described.

The main shaft a supported at its ends in suitable standards or uprights 0. a erected upon a base-plate a, has fast on it, substantially near one end, a pinion 01, (see Figs. 1,

2, and 3,) in mesh with an intermediate pinion a on a stud or shaft (1 having bearings in an upright a, (see Fig. 1,) the said intermediate pinion meshing with a gear e on the periphery of a hollow cylinder or drum c1 loosely mounted onthe shaft a, as will be described, the said drum having extended from one of its faces an elongated hub 04 having bearings in a suitable box 0. 5, supported by the upright 01., the opposite side or face a of the said drum being removable and provided with a hub a, the said removable as clearly shown in Fig. 5, and having its opposite end supported in a journal-box Q on the upright (1 The shaft a within the hollow drum a has fast on it a bevel-pinion c (see Fig. 5,) which meshes with a like pinion or gear 6632, (see Fig. 3,) fast on a shaft a located within the drum a and having bearings in arms or lugs a a secured to or forming part of the face 2 of the drum.

The shaft a is provided, as'shown, with a worm a, which meshes with a worm-gear a (see Fig. 3) on a stud or arbor having bearings in the face 2 of the drum, the said stud or arbor having fast on it a pinion a (see dotted lines, Fig. 3,) which meshes with a gear a, fast on the end of the shaft (L12. (See Figs. 3 and 5.)

The shaft a is also driven from the drumgear (1 preferably by a friction speed-changing device, as will now be described, by which the rotation of the thread-guide may be differentiated from that of the cop-shaft.

The drum-gear 0 meshes with an intermediate gear a, (see Fig. 3,) loose on a stud or arbor a, supported in an upright or standard (L43, located at what may be regarded as the rear side of the machine, the said intermediate gear meshing with a gear a, fast on the shaft 61 of a cone 0., the said cone-shaft having bearings in the uprights (e 61, The cone or cooperates with a cone G48 on the shaft a, located substantially above the shaft a, the cone a being extended in the opposite direction from the cone (1. and frictionally connected therewith, and in the present instance this frictional connection is effected by means of a friction roller or wheel C650, interposed between and making frictional contact with the said cones.

The friction wheel or roller (1 is frictionally driven by the cone a and in turn frictionally drives the cone a and is adjustable longitudinally on its shaft or supporting-rod C652 to vary the speed of rotation of the driven cone a and thereby vary the speed of the rotary thread-guide, as will be described.

The shaft (L52 is supported, as shown, in the upright a and in an upright a and the friction-wheel a may be secured on the said shaft or rod in any suitable manner, as by means of collars a a on opposite sides of the wheel, which are secured on the rod by set-screws a, only one of which is shown in Fig. 1. The main driving-shaft a may be driven in any suitable manner and is herein shown as provided with a pulley a, normally loose thereon and adapted to be rendered fast on the said shaft by engagement of the said loose pulley with a friction-disk a, keyed or otherwise secured to the shaft a to rotate therewith. This engagement of the loose pulley (1 with the friction-disk a may be effected in any suitable manner, and in the present instance it is effected by means of a spring C675, encircling the shaft a between a collar a fast thereon and the hub a of the loose pulley.

The loose pulley a is automatically disengaged from the friction-disk a preferably as herein shown, the hub a of the said pulley having an annular groove a, provided with a beveled or inclined wall 4, with which 00- operates the end of a plunger or rod 00 movable vertically in a suitable socket in an upright post a secured to the bed-plate a" in any suitable manner, the said rod being acted upon by a spring a (see dotted lines, Fig. 6,) located in a socket in the post ct below the rod a when the said rod is free to move, as will be described. The rod a is normally held down in its socket by a lever a pivoted, as at a, to an arm a, extended from the post a, the said lever, as shown, having a slot (1 into which projects a rod, bar, or arm 0e secured to the plunger-rod a and extended through a vertical slot in the post at, the rod a being extended into the slot in the lever, so that when the lever is turned downward the plunger is forced down into its socket against the action of the spring therein. This downward movement of the lever and the plunger withdraws the latter from the groove in the hub a", thereby leaving the loose pulley free to be acted upon by the spring a, which throws it into engagement with the friction-disk (r and starts the machine in operation. The lever a is locked in its lowered position, as herein shown, by means of a latch or finger b on the end of a crank [or arm I) on a rock-shaft 12 having bearings in suitable lugs b erected upon the base-plate a", the said latch or finger being carried over a pin or projection b on the lever, when the arm (b carrying the cop-shaft, is rocked to bring the cop toward and preferably in contact with the rotary threadguide. The rocking of the shaft 12 from the shaft a is effected, as herein shown, by means of a crank or arm I), depending from the shaft a and having pivotally connected to it a link I)", provided with a slot b into which is extended a pin or projection, represented in Fig. 4 as a screw b carried by a crank h on the rock-shaft 6 The link I) is provided at its end, as shown, with an adj usting screw Z2 which is adapted to be brought into engagement with the screw 12 when the link 6 is moved in the direction of the arrow 20, Fig. 4:, which movement takes place as the diameter of the ball wound on the cop increases, for by reference to Figs. 1 and 2 it will be seen that as the ball increases in diameter the rocking support a for the cop-shaft is turned in the direction opposite to that indicated by the arrow '20, Fig. 4, by reason of the ball bearing against a substantially thin arm at, horizontally extended from an upright d secured to the base a", and the crank-arm b is moved in the direction of said arrow, which crank-arm carries the link I) in the same direction and IIO moves the stop 19 toward the screw b and when the said ball has attained the desired diameter the stop b at such time engages the screw 12 and rocks the shaft 12 in the direction indicated by the arrow 20 and withdraws the latch 12 from engagement with the pin b thereby permitting the plunger-rod 0. to be thrown upward into engagement with the beveled wall 4 of the groove a and thereby move the pulley a out of contact with the friction-disk a.

The apparatus may and preferably will be provided with a tension device of any suitable or desired construction to keep the thread supplied to the cop under proper or desired tension.

In operation the thread ,or other material to be wound on the cop tube or cylinder A is first secured on the cop-tube by winding it upon the same for one ortwo turns, and it is then placed in the cam or inclined slot 11 in the periphery of the rotary thread-guide a after which the machine is started in motion, the main shaft a rotating the gears or pinions a ct and the dru m-gear a. The drumgear (L22 rotates the gears or pinions (L a and thereby rotates the driving-cone a, which rotates the driven cone a and its shaft a through the friction wheel or roller (1 The driven-cone shaft a produces a differential rotation of the rotary thread-guide in the following manner, namely: The bevel-pinion a on the shaft 64 drives the bevel-gear 66 its shaft (r the worm ed, the worm-gear a, its shaft 04 the pinion a, the gear c0 and the shaft (Mon which the rotary threadguide is fast. The rotary thread-guide by means of the cam-slot 0, carries the thread along the rotary cop-tube longitudinallyin opposite directions and lays the said thread on the said holder in successive layers, thereby obtaining a close and firm wind, and owing to the fact that the thread-guide rotates the winding of the thread on the cop is very rapid and the ball is built up or wound to the desired diameter or size very quickly, thereby largely increasing the output of the machine in agiven time.

By adjusting the friction roll or wheel longitndinally on its shaft or rod the speed of the driven cone a, its shaft a, and the parts driven by it may be regulated according to the size of thread to be wound on the cop. With the present arrangement afast speed of the thread-guide may be obtained by moving the wheel to the right in Fig. lthat is, so as to engage it with the large diameter of the driving-cone a and with the small diameter of the driven cone a -and a slow speed of the thread-guide may be obtained by moving the said wheel into contact with the small diameter of the driving-cone and into contact with the large diameter of the driven cone.

I have herein shown one form of friction speed-changing mechanism for effecting a change in the speed of rotation of the rotary thread-guide; butI do not desire to limit my invention to the particular construction herein shown.

The cop tube and shaft are normally held toward the rotary thread-guide by means of a weight, (not shown,) which is fastened to the lower end of a rod, cord, or chain e, (see Fig. 4,) secured to a crank or arm 6, fast to the rock-shaft a The arm at is located in close proximity to the rotary thread-guide,

with its upper edge substantially in a horizontal line through the rotary thread-guide, which acts as a support for the thread in the cam-slot 61.
