STOP-MOTION FOR SPOOLING- OR LIKE MACHINES.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed June 11, 1913. Serial No. 772,965. I

To all whom it may concern:

Be it known that I, JAMES H. OCoNNELL, a citizen of the United States, residing at Lawrence, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Stop-Motions for Spooling or like Machines, of which the following is a specification.

My invention relates to spooling or like machines and consists particularly of an improved stopping-mechanism therefor adapted to arrest the rotation of the spool or other yarn-holder after the latter has been filled with yarn or thread.

The object of my improvement is to provide a means for stopping the spool without undue friction on the yarn or other material being wound, and further to provide for adjusting the stopping-mechanism for different sizes of spools.

The invention is fully set forth in the following specification, illustrated by the accompanying drawings, in which like letters of reference designate like parts.

In the drawings :Figure l is an end elevation of a portion of a usual type of spooling-machine, showing my new device applied thereto; Fig. 2 is an enlarged view of the device shown in connection with the winding-spindle on which the spool is rotated; Fig. 3 is an elevation of one of the main elements of the device, being a sectional View taken on the line XX of Fig. 2, looking in the direction indicated by the arrow 00.

Referring to Fig. 1, A designates the end frame of a well known type of spooling-machine having a front rail A in which are bearings for the winding-spindles B. The spindles B are arranged along the rail A in multiple and are usually driven individually from a main driving-drum D, the latter being rotated with the shaft cl. As here shown, each spindle is provided with a grooved pulley or whirl 6 around which passes an endless belt 0 leading from the drum D. In some types of spoolers the spindles are arranged to be driven from a flat belt running parallel with the rail A and in such cases the belt contacts with a relatively broad-faced pulley b. The spindles here illustrated are provided with both types of pulleys b, b which are constructed in one piece, this construction adapting them for use on either style of machine. Referring to Fig. 2, the upper end of the pulley b is formed with an enlarged flange b which serves as a driving-means for the spool. The spool S or other yarn-carrier is mounted on the spindle B on top of the pulley b and is driven through the frictional contact of its head 8 with the upper face of the flange 6 The thread or yarn is traversed on the spool by means of the usual reciprocating guide-rail, not here shown as it has no relation to the present invention. The above named parts are all common to generallyused types of spoofing-machines and my new device is applied thereto as now described.

Extending along the front of the machine parallel with the rail A and in back of the spindles B I provide a horizontal rod E. The rod E may be supported in any suitable manner and as here shown is held in brackets e fastened to the end-frames A by means of screws 6. The individual stopping-devices for the separate spindles are mounted along the rod E and I have here shown only one as all the devices are alike in arrangement and operation. Positioned adjacent each spindle is an arm F formed with a hub f surrounding the rod E and secured in place by the set-screw f. The arm F has a slot f through which extends the flattened end of a stud G,the latter secured in position by binding its shoulder 9 against the arm by means of the washer g and nut Pivoted on the stud G is a bell-crank lever H which acts as the sizing-lever for the spool. The upper end of the upright arm h is turned down to receive a roller h which is held thereon by a cotter-pin if, or through any other suitable means. The roller it is preferably formed of wood, fiber or some other light material and has a smooth peripheral surface adapted to contact with the surface of the yarn wound on the spool S. Secured to the lower, depending end of the arm 72. is a stud K extending at rightangles thereto and forming the horizontal arm of the "bell crank. The stud K might be formed as a part of the arm h or can be fastened thereto in any convenient manner. As here illustrated the stud K has a reduced portion 70 extending through a hole It in the arm H and fastened in place by the setscrew If. The outer end of the stud K is also reduced in diameter at 70 to provide a bearing for an eccentric disk L, arranged in position under the head 8 of the spool S as shown in detail in Fig. 3. The

disk L has a transverse hole Z, bored slightly eccentric to its perimeter, by which it is mounted on the bearing and a cotter-pin k or any other suitable means serves to hold it in place. The periphery of the disk L is formed with a groove Z in which is secured a circumferential band Z of rough-' surfaced material such as leather or fiber. Driven into the side of the disk L is a pin Z which is adapted to contact with a pin 70 on the top of the stud K when the disk is rotated on its bearing is. The weight of the arm or stud K and disk L normally tends to tilt the upright arm it toward the spindle B as shown in Fig. 2, and movement of the arm in this direction is limited by a stoppin 7& adapted to strike against the under side of the supporting arm F.

The operation of the complete device is as follows: The empty spool S is placed on the spindle B and driven therefrom through contact of its lower head 8 with the driving flange 6 As the yarn mass 1 is wound up on the spool and approaches the full diameter its periphery comes into cont-act with the roller h on the arm h as illustrated by dash lines in Fig. 2. Now, as the diameter of the yarn increases the arm it will be carried to the right, away from the spindle B, until the edge of the eccentric disk L on the arm K comes into contact with the under side of the spool-head 8. Immediately this contact takes place the turning of the spool will act to rotate the disk L until the pin i strikes the pin 70, it being immaterial in which direction the spool is turning. As the disk L is turned on its bearing the eccentric relation of its periphery thereto will cause the spool S to be raised clear of the flange b and thereafter it will be held in the position illustrated by dotted lines in Fig. 2. Through this action the spool is removed from frictional contact with its driving-means and restrained from further rotation thereby after the yarn has been wound to the proper diameter to fill the spool. After the spool is filled it is removed by the operator and when the disk L is released it will be returned to its initial position through gravity, so that the whole device remains inoperative until the next spool is filled.

It will be seen that by adjusting the stud G in the slot f the roller it can be set at different distances from the spindle B to adapt the device for various sizes of spools and to regulate the amount of yarn to be wound thereon before the rotation of the spool is arrested. It will also be observed that the roller it has only a slight contact with the yarn on the spool and as the moving elements of the device are relatively light in weight very little pressure is exerted against the yarn. In devices heretofore employed for arresting the turning of the a certain diameter.

spool at the completion of the winding it has been the usual practice to hold the spool against the rotative action of the driving-means without carrying it away from contact therewith. The usual method of accomplishing this has been to provide a relatively broad rail or other friction-surface against which the yarn on the spool is brought to bear after the winding reaches This method of stopping the spool is open to serious objection, however, as it imposes undue pressure on the yarn besides causing an abrasive action on the surface thereof. It has been found that in many cases the yarn on th spool is badly crushed and matted together by this action of the stopping-means, and often the outer layers of winding will be roughed up and abraded to such an extent that a considerable yardage must be reeled off and discarded as waste. My present improvement eliminates all of these objectionable features by relieving the yarn of undue pressure or rubbing friction and provides a much more efiicient and reliable stoppingdevice for the spool. It can be applied to practically all types of spoofing-machines and is also adaptable for bobbin winders or other apparatus of like arrangement.

Various modifications might be made in the form and structure of my device, or in the method of applying it to use, without departing from the spirit or scope of the invention.

Therefore, without limiting myself to the exact embodiment here shown, what I claim 1s 1. In a stoppingmechanism for spoolers or like machines, the combination with a winding-spindle having a. flange adapted to engage the head of the spool to rotate the latter through frictional contact therewith, of a pivoted bell-crank lever adapted to be moved through contact with the yarn wound on the spool, and an eccentric disk mounted rotatably on one arm of the bell-crank lever and adapted to engage the head of the spool to be rotated therefrom to raise the spool from the driving-flange.

2. In a stopping-mechanism for spoolers or like machines, the combination with a windingspindle having means to engage the spool to rotate the latter through frictional contact therewith, of a pivoted bellcrank lever, a roller mounted rotatably on one arm of the bell-crank lever and adapted to engage the yarn on the spool, and a disk pivoted on the other arm of the bell-crank lever with its pivot eccentric to its periphery and adapted to be carried into engagement with the spool through movement of the bell-crank lever to be rotated thereby to move the spool away from the driving means.

3. In a stopping-mechanism for spoolers or like machines, the combination with a winding-spindle having means to frictionally engage the spool to rotate the latter, of a bell-crank lever adapted to be moved through engagement with the yarn on the spool when the mass reaches a predetermined diameter, a disk rotatably mounted on one arm of the bell-crank lever eccentric to its bearing and arranged with its periphery adapted to engage the spool when the bell-crank lever is moved, and means to limit the movement of the disk when the latter is rotated by contact with the spool to maintain the spool away from the driving-means.

4. In a stopping-mechanism for spoolers or like machines, the combination with a winding-spindle having means to frictionally engage the spool to drive the latter, of a fixed arm supported adjacent said spindle, a bearing adjustable on said arm, a rocka lole bell-crank lever having an arm pivoted on the bearing to adapt it to be moved through engagement with the yarn mass wound on the spool, a stud extending at right-angles from the pivoted arm, a disk eccentrically mounted on said stud with its periphery adapted to engage the head of the spool, and means to limit the rotative movement of the disk.

In testimony whereof I afiix my signature in presence of two witnesses.
