Application filed June 4. 1904. Serial No. 211,203.

2'9 (ZZZ whom it may concern.-

Be it known that I, SIMON W. WARDWELL, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Controlling Means for Winding-Machines,of which the followingis a specification.

My invention relates to winding-machines, and particularly to the means for controlling their operation.

The object of my invention is to provide improved devices for starting the machine and for stopping it automatically upon the breakage of the supply or at the finish of the cop. The invention is fully set forth in the following specification, illustrated by the accompanying drawings, in which Figure 1 is a front view of the winding-machine, showing the relation of the starting and stopping mechanism; Fig. 2, an enlarged detail view of the braking device; Fig. 3, a detail view of the stopping-lever; Fig. 4:, an enlarged sectional view on the line 1 1, Fig. 1; Fig. 5, a detail view of the threading-guide, showing its relation to the stopping-lever.

The machine in general is of a familiar type known to those versed in the art as the Universal winding-machine.

The main frame A supports bearings for the winding-spindle B and cam-shaft C, the latter carrying the cam (not shown) which reciprocates the thread-guide D. The thread-guide is carried in the traverse-frame E, the latter being pivoted on the cam-shaft C to swing to allow the guide to move away from the Winding-spindle as the cop is built up thereon. The devices shown at G and described in my pending application, Serial No. 135,768, filed December 18, 1902, serve to apply pressure on the traverse-frame E to resist the outward movement of the guide, and to prevent this pressure forcing the guide back toward the spindle a detent is provided on the frame E. I prefer to make this detent in the form shown and described in my pending application, Serial No. 211,204, filed June 4:, 1904:, in which an arm 9, operated by a spring-pressed finger-lever f, engages a V-shaped groove in the sector H through its wedge-shaped extremity e".

The sector H is pivoted at h on the main its spring.

frame A and besides serving as a track for the arm 6 to bear on performs the additional func tion of a detent for the starting-leverJ when the latter is thrown into position to start the machine. The lever J is mounted on a rockshaft j, the latter extending to the back of the machine and connected to engage the driving mechanism. For this latter any usual device may be used, preferably that shown and described in my pending application, Serial N 0. 211,205, filed June 4, 1904. With this arrangement the driving-pulley is thrown in and out of engagement with a suitable clutch on the spindle B by a rock-lever on the shaft j. The rock-shaft j is operated by any suitable spring arrangement to turn in the direction indicated by the arrow, Fig. 1, to release the driving-pulley from the clutch. For operating the rock-lever I have preferred to show a lever s, fastened to the rear end of the rockshaft 1' and connected by a coiled spring 2? to the machine frame. Another suitable arrangement would be to provide a coiled spring on the rock-shaft, held under torsion by having one end fast in the frame and the other socured to the shaft. To engage the drivingpulley with the clutch, the shaft is rocked in the opposite direction by means of the startinglever J, and the shaft is held in this position (see Fig. 1) by the arm Z, engaging the extension h of the sector H. The arm Z extends from the hub of the lever J and is formed at its lower extremity with a lug Z, engaging a shoulder 7& on the extension of the sector H. Beyond this shoulder is a bearing-surface /1 which rests on the lug Z when the latter has been released from the shoulder so that the sector H is always supported at its free end by the arm Z. The weight of the sector maintains the lug Z and shoulder k in engagement, and when it is desired to stop the machine it is only necessary to raise the free end of the sector-to release the arm Z and allow the shaft 1' to be rocked under the action of To cause immediate arrestment of the winding-spindle and of the cam-shaft connected therewith, I provide a braking device consisting of the brake m, adapted to engage a disk or collar 6 on the winding-spindle.

The brake m is pivoted on an arm extending grooves (see Fig. 2) adapted to pinch upon the correspondingly-shaped rim of the disk 5.

In order that the operation of the machine may be arrested upon the breaking or running out of the supply, I provide a stoppinglever K, adapted to release the detent of the starting-lever J. The lever. K for lightness is preferably formed of wire bent in triangular form and suspended at its apex on the free end of the sector H. One leg of the lever K is made heavier than the others by coiling the wire of the base-piece about it and is formed at its extremity with a bearingbar is for the thread, terminating in the curved hook 70 This bearing-bar it hangs adjacent the top of the tension device L and is adapted to be supported on the thread as it leads to the thread-guide. The other leg 10' is reinforced at its extremity by bending back the wire a short distance before carrying it across to the leg 76. The tension device is of the usual form, having two opposed plates with alternating parallel bars bearing on the thread to sinuate its course. One of the plates 0 is movable to adapt it to swing toward the other fixed plate, and both plates are supported by a rod P, passing through cars at their extremities, the fixed plate being held rigid by the screw q and the movable plate hinged on the rod. The rod P is bent at its upper extremity in a semicircular form (see Fig. 5) to form a guide for threading the supply under the bearing-bar 7c and terminates in a loop 19, passing around the bar Zr to serve as a limit to the movement of the latter.

The cam-shaft C carries a disk 0 at its outer end, the latter formed with a corrugated or fluted rim and rotating in the direction indicated by the arrow. When the lever K is supported by the thread, as shown in Fig. l, the leg Z0 of the lever hangs adjacent the face of the disk 0," but when the thread breaks or runs out the weight of the leg Z3 carries the extremity of the leg Ir into engagement withthe disk and the rotation of the latter moves the leverK bodily upward, raising the sector H and releasing the lever J.

In order that the relation of the lever K to the disk 0 may be such as to cause a quick and positive action of the stopping devices, I provide means for adjusting the fulcrum of the lever on the sector H. As shown in- Fig. 3, the lever K is supported on a pivot-pin i, screwed into the head z' of the stud t the stud screwing into the end of the sector H. The pivot-pin is arranged eccentric to the stud and the head of the latter is knurled to adapt it to be grasped by the fingers. When the stud is turned slightly, the pin is moved toward or away from the disk 0 to adjust the lever K in relation thereto. A check-nut i is provided to screw against the sector to secure the stud vin position.

In machines of this class it is desirable to have a stop to operate when the cop or package has reached its predetermined diameter. For this purpose I provide the member R, adjustable along the sector H and having a beveled under surface which is engaged by a portion of the traverseframe E to lift the sector and release the detent of the lever J. The member R is preferably formed of sheet metal bent in the form shown in Fig. 4, with a hooked extension reaching up in the groove of the sector H and bearing on the bottom. To secure the member in position on the sector, I provide the following novel means: A thumb-screw r engages the upper bent por tion of the member R and is bored to receive the plunger r. This latter is formed with a head r fitting the larger section of the bore of the screw 1", and with a shank extending through the smaller bore for a bearing and riveted at its end to prevent displacement.- Surroundingthe shank of the plunger is a coiled spring r bearing on the bottom of the bore and the head o and tending to force the plunger down on the sector H. The upper face of the sector is provided with a shallow groove 7t, and the end of the plunger 9" is of rectangular form to adapt it to fit the groove. The pressure of the spring r causes friction between the plunger and the sector H, and this slight resistance renders the member more susceptible to fine adjustment. The member R may be moved the slightest degree with utmost precision and owing to the frictional contact will remain stationary until set against the sector H. This is accomplished by screwing the screw 7" through the member, the lower end of the screw bearing on the shoulder formed by the rectangular end of the plunger and binding'the latter in the groove /t*.

The operation of the machine is as follows: The thread is drawn from the supply up through the tensions, carried over against the curved guide portion of the rod P, and bearing against the latter is directed under the bearing-bar 7c. Thence it is led up through the eye of the thread-guide and secured to the winding spindle, the traverse frame being placed in position for the guide to bear on the spindle. To start the winding, the lever J is swung in the opposite direction from that indicated by the arrow until the lug Z engages the shoulder [02, Fig. 1. The swinging of the lever J releases the brake from the disk 6 and through the arrangement at the back of the machine causes the driving-pulley to engage the spindle B to rotate the latter, which through suitable connections also drives the cam-shaft C. The lever K is supported in the position shown by the thread passing under the bar 7c; but when the thread breaks-or runs out the lever is released, allowing the extremity to engage the disk 0, which carries it upward to release the arm Z. 'When the arm Z is released,the spring connected to the shaft 1' rocks the latter to disengage the driving-pulley from its clutch, and the brake ITS ' with the main frame sired- Automatic stopping devices have before been designed to operate in connection with winding-machines, and I do not here claim the combination broadly; but what I do desire to secure protection for is the particular.
