'THREAD-WINDINGLMACHINE.

SPECIFICATION forming part of Letters Patent No. 693,196, dated February 11, 1902.

Application filed March a, 1901. Serial No. 50,063. (No model.)

T0 ctZZ whom it may concern.-

Be it known that I, PET R J. WESTPHAL, a citizen of the United States of America, residing'at Holyoke, in the county of Ham pden and State of Massachusetts; have invented new and useful Improvementsin Thread-Winding Machines, of which the following is a specification. i

This invention relates'to improvements in thread-winding machines, and has especial reference to the improvement of devices for regulating the pressure which the cops are subjected to by the thread-guide and to'means for varying the tension placed upon the thread as it passes onto the cop, whereby said tension may be changed or regulated in proportion to the change in the diameter of the cops.

A further object of theinvention lies in the adaptation of a stop-motion operated by the movement of the thread-guide and means of adjustment for said stop-motion, whereby it may be operated by said guide to determine the diameter of a cop at any point during the upward movement of the guide.

The invention consists in the construction as hereinafter fully described,and'pointed out in the claim.

In the drawings, which consist of two figures, Figure 1 is aperspective view, partly broken away, howing one end of a threadwinding machine having my invention adapted thereto; and Fig. 2 is a longitudinal section through the thread -tension's,- showing the means employed whereby the degree of tension applied to the thread'may be varied according to the diameter of the cop being wound.

Referring to the drawings, a represents a part of the frame of a thread-winding ma,- chine in which is mounted the usual drivingshaft b, run by a belt 0 and geared by devices not shown in the drawings with the spindle (1, one end of which projects beyond its bearing, as shown, and which receives a cop-tube on which thecops e are wound. Threads from suitable bobbins pass around or partly around the disk tension devices f,

ing 2', in which it has a sliding movement. Nearthe lower end of said stem a postj is socured'thereto at right angles and projects from either side thereof. On one end of said post suitable weights it may be hung,whereby said guide-plate g may be made to bear with more or less pressure on the cops as they transverse slot 1) at that point where the arm Z passes through the slot m.

The upper end of the arm Z has pivoted thereto a shorter arm q, extending downwardly through the slot 'm in the arbor n, and the lower end of said arm g has a screw 1 passing therethrough, whose point rests against the arm 1, and the latter is Slotted and has a screw 3 passing through said slot and threaded into a hole in the arm q.' By means of the screws the arm q may be swung at a greater or less angle to the arm I, and the screw 1 is used as a set-screw for holding-it in the desired position. Thus the arm q, together with the upper end of the arm Z, forms a wedge, the arm Z, as shown in Fig. 2, bearing against the arm 0, and the arm q bearing against one end-0f the slot m in the arbor n. 1 When the guide-plate g rests upon the spindle d, theends of the arms q and Z at the point of their union will lie just within the said slot m, and

when in this position the maximum tension will be applied to the disks f by means of the spring t. v The operation of this tension device is as follows: The arloorn is loosely held in its sup port 0--that is to say, it is free to move endwise therein. The upper ends of the arms q and Z or some part thereof always occupy the slot m. A spring to, superior intensi'on to the spring 25, is applied to one end of the arbor n and constantly holds the end of the slot m againstthe'in clined face of the armq. Now'in adj usting the tension under which the threads .are to be. wound onto the cop the spring-tie by a suitable nut compressed more or less until the requisite resistance to separation of the disks f is attained. Now as the cops inro J crease in size the guide-plate g is raised and with it the stem'h and with the latter the arms Z and q and the inclined surface of the latter forced against the end of the slot m, the armZ finding its abutment against the arm 0. The arbor n is given a longitudinal movement in its support toward the spring 25, thus taking from the latter a certain degree of its compression or tension and proportionately permitting the more easy separation of the tension-disksf. It is thus seen that by means of the arm q, whose degree of inclination may be varied by means of the screws 7' and s, as described, any relaxation of the normal tension as the cops e are built up may be effected as desired.

It has been found in practice that where cops are to be wound having comparatively large diameters if the same tension is maintained in winding from the center outward by the time the cop is completed the tension of the center thereof is so great as to have a tendency to not only crush the tube, but to throw said center part out of line, causing it to bulge, and it is to overcome this de-' feet that means are provided herein for decreasing gradually the tension on the thread as the cop increases in diameter. Furthermore, it is found that more or less pressure upon the cops by the guide-plate gives an improved finish to the cop, and to provide for this pressure weights may be hung on the post j on the stem of the guide-plate g. It has been found desirable also in practice to prevent the weight of the guide-plate and its attached parts from resting upon the cop-tube at the beginning of the winding operation. Therefore to relieve the cop of the weight of said plate and its parts during the first few courses a support for said plate is provided, which consists of an adjusting-screw v, supported in a post 10, screwed into the frame,

and the stem h of the guide-plate rests on the top of this screw when the cop-tube has no thread wound upon it and holds the guideplate just out of contact with said tube.

The successful operation of said winding machine requires that the machine shall stop automatically when the desired amount of thread has been wound on the cop. The stopmotion herein shown consists of a spring-actuated belt-shipper rod or and means for shifting it to stop and start the machine. When the belt a, which is engaged by a fork on the shipper-rod, is drawn onto the tight pulley, (indicated by y in the drawings,) a spring 2 is compressed by said movement of the shipper-rod. This spring is, as shown, wound around the rod and the rod and spring inclosed in a suitable tubular support 1. At the time the belt arrives fairly onto the tight pulley y a spring-actuated latch 2 snaps into a notch on said shipper rod and holds it against return movement. This latch 2 is pivoted at 3 to the frame of the machine, and its opposite end is connected by an endwise-adjustable connection lwith one end of a swinging Ushaped yoke, one arm 5 of which is pivotally connected with the connection 4.. Said yoke is pivotally supported in a bearing 6, the other arm 7 of said yoke reaching over into the path of the post j in a position substantially parallel with the arm 5. A spring 8 is connected with the end of the arm 5 and the frame of the machine, the function of said spring being to hold the latch 2 in engagement with the shipper-rod.

It will be readily seen by the foregoing description that as the diameter of the cop increases the stem 71. will rise, carrying with it the post j, which will when the cop has reached the desired diameter cause the arm 7 to be swung upward, whereby through the described connections with said arm the latch 2 will become disengaged from the shipperrod and the spring on the latter will ship the belt 0 from the tight to the loose pulley of the machine, arresting its motion. It is obvious, however, that owing to the fact that the guide-plate on certain sizes of cops will rise to a greater height than when smaller cops are to be wound it is necessary to provide adjusting means for said stop-motion, whereby the disengagement of the latch 2 with the shipper-rod may be effected when any desired diameter of cop has been attained. In other words, the stop-motion adjustment is such that it maybe caused to operate at any point during the upward movement of the guide-plate g. This range of adj ustability in the stop-motion is attained by means of the endwise-adjustable connection 4:. This connection is made in two parts united by a sleeve having a right and left hand thread,- into which the said two parts are screwed. B y shortening said connection 4 the stop-motion maybe adjusted to a cop of larger diameter, and by lengthening it it may be adjusted to arrest the motion of the machine upon the attainment of a smaller diameter. To adjust the stop-motion to operate at a given pointduring" the vertical movement of the guideplate, the latter may be raised manually to the desired height, representing the desired diameter of the cop, and the screw connection 4 be then manipulated to bring the latch 2 into the detent or notch of the shipper-rod and the arm 7 toa bearing upon the post j. WVhen the guide-plate reaches this point of its upward movement in the operation of winding the cop, the arm 7 will be struck by the post j and the latch 2 tripped, and the shipper-rod will then be moved to shift the belt onto the loose pulley of the machine.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

In a thread-winding machine, a spindle on which the thread is wound, a thread-guide bearing on the thread being wound, and

adapted to be raised vertically by the building up of the thread on said spindle; a tension device consisting of a series of disks held ment to said arbor to diminish the pressure whereby said disks are held together, substantially as described.

yieldingly together, an arbor on which said disks are supported, and a support for the arbor, there being a slot through the latter and said support; awe dge connected with said 5 thread-guide and entering said slots, whereby the movement of said guide vertically will move said wedge and impart endwise move- Witnesses:
