SPOOLlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 514,884, dated February 13, 1894.

Application filed April 25, 1893- Serial No. 471,763. (No model.) I

To all whom it may concern:

Be it known that I, JOHN W. FOSTER, f Westfield, county of Hampden, State of Massachusetts, have invented an Improvement in Spool1 ng-Machines, of which the following descriptlon, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In textile manufacture threads of cotton, silk, and of other fibers in form of skeins have subsequently to be wound into more compact form in order that the thread may be used in different manufactures or machines, and most frequently this skein thread is wound on the cones to form conical masses of thread, the cones being used inquill-winding machines, and 1n knitting and other machines. These skeins of thread are commonly stretched over swlfts or reels and inpractice it has been customary in getting the thread into conical masses to first wind the thread upon a spool and then redraw or rewind the thread from the spool upon'a cone, thus requiring two handlings in order to get the thread into the form of a conical mass. This method has been practiced because heretofore it has been considered impracticable to satisfactorily and economically wind the thread directly from the skein upon a cone, and chiefly because of the differences in the diameter of the cone and the consequent variations in the amount of thread'required to reach around the cone at its large and at its small end. It will be obvious that different portions of the surface of a conical shell mounted on a journal rotating at a certain speed will run at different surface speeds according to the diameter of the conical shell, and inasmuch as the speed ofrotation of the swift or reel is determined by the strain of the rotating cone on the thread, the speed of rotation of the swift must consequently vary and a varying amount of thread will be let ofi. In my efforts to overcome this difficulty in cone winding so as to make it possible to wind thread, by which term,l mean to include any thread of any ma terial, directly from the skein upon a conical shell, I have devised What I shall call a take up or slack-thread controller, which I have so constructed as to enable it to take care of all Y the slack thread incident to the winding operation and due to variations in the diameter of the conical shell between its large and its small ends; and l have so devised said takeup or slack-thread controller that it will offectually care for and control the thread and insure the continuance of the Winding operation, and I have also devised said device that it through intermediate devices will release a drop whenever a tangle or knot occurs in the skein which would tend to break the thread or prevent the proper rotation of the swift or reel containing the skein. Q

My apparatus has also been so devised that it will act upon the occurrence of a knot of improper size and effect the stopping of the winding operation until the defect has been removed, and said device will also act in case the thread breaks.

While my invention is most important and valuable in cone winding, yet it has very material advantages when used t'or winding thread from the skein onto a cylindrical shell or tube, for in use, the thread, whatever the external shape of the shell, is wound after the manner designated under the term cross-winding so that large masses of thread put onto the shells may be drawn off the ends thereof without rotating the thread masses when such practice is desired.

Figure 1,in side elevation showsasufticient portion of a spooling machine with my improvements'added to enable my invention to be understood; Fig. 2, a portion of the grooved drum for rotating the winding roll or driving the mass of thread being wound. Fig. 3, is an enlarged detail of the track audits supporting frame, and the stop-trigger and slack trigger, viewing the same as in Fig. 1, but enlarged. Fig. 4, is a view of the devices in Fig. 3, looking from the left. Fig. 5,is a view looking at Fig. 3 from the rear side. Figs. 6 and 7, are details to be referred to, one showing the stop-trigger and the other the slacktrigger in plan view. Fig. 8, shows the remainder of the spindle carrier broken oif from Fig. 1. Fig. 9, is a top or plan View of the front end of the spindle carrier showing the spindle as adapted to hold a shell of conical shape; and Fig. 10, an enlarged detail showing thespindle shaped to receive a tubular shell.

The frame-work A is and may be as usual in spooling machines, it being of suitable shape to sustain the working parts.

The machine in practice will or may have at each side a suitable longitudinal shaft a, provided at suitable distances apart with like drums a, one for each thread mass to be wound, each drum having suitable crossing grooves e see Fig. 2, in which enters asuitable foot or shoe Z) of a suitable traverse guide I) adapted to slide back and forth on a guide bar 12 as the said drum is rotated.

Each rotating drum a has resting directly upon it a winding roll 24: which is rotated by the drum so long as the roll contacts therewith. The winding roll acts to rotate a spindle marked din Figs. 1 to 9, it carrying, as supposed in said figures a conical shaped shell 1), preferably of paper, upon which the thread 3 being delivered from the skein is wound. The spindle d has journals or ends mounted in hearings in a suitable carrier 0 but partially represented in Fig. 1, the remaining part being, however, represented in Fig. 8, said carrier being so mounted as to be able to rise as the mass of thread wound on the shell increases in diameter. The journals of the winding roll rest in suitable bearings 25 at the upper ends of stands 26 attached to the stringer A.

The carrier 0 see Fig. 8, has a shank c which enters, as shown, a socket piece 0 pivoted at c on an upright erected on the lower frame-work, a suitable screw 0 permitting the yoke part of the carrier supporting the spindle d, to be tipped more or less, as when the spindle is to carry a conical shell, as b, best represented in Fig, 9, but as stated, while my apparatus is very essential for winding thread in conical masses, yet it may be used to great advantage to wind threads upon cylindrical paper tubes or shells, as represented in modification Fig. 10, wherein the cylindrical shell is marked t, the spindle being marked (1 it having cylindrical collars 25 rather than conical collars (Z as represented in Fig. 9.

9 represents a lever having at its inner end a lifting devicef, which, when moved vertically, as will be described, acts upon the journals of the winding roll 24 and lifts said roll from its bearings 25 so as to break the contact of the said roll with the drum, and thus stop the rotation of the roll and also the winding operation of the thread upon the shell carried by the spindle.

The stringer A? constituting a part of the frame-work has a stud A from which depends a leg 9 pivoted at 9 said leg having pivoted upon it at or near its lower end at g a leg lever 71, said leg lever having at its outer end a suitable projection, as 3, above which is suspended a eo-operating drop 7t, represented as a lever pivoted at 28. The lever g at its upper side between suitable projections, is provided with a cam face, and the lower end of the leg or a part carried thereby presses on said cam face during the vibrations of said leg, as will be described, about its pivot g. The inner end of the leg lever h when elevated or put into its abnormal position by the falling of the drop h will be struck by one of the projections m on a ratchet wheel connected with a shaft m having its journals mounted in suitable bearings of a stand m suitably attached to the frame-work, the said shaft in practice being rotated as provided for in United States Patent No. 40%,831, granted tome June 11, 1889.

Many of the parts thus far specifically referred to by letter, such as the drum, the winding roll, the spindle-carrier, the lever g and lifting device are substantially the same as represented in my United States Patent No. 499,668, granted June 13, 1893.

I will now specifically describe the improvements which I have added to the parts thus briefly referred to. The frame-work has upon it at suitable intervals suitable uprights or stands A adapted to sustain asuitable swift or reel A to contain askein of thread, silk, or other material to be wound upon the shell of conical or other form. The frame-work has attached to it by suitable bolts suitable stands 19 constituting bearings for a rod or beam D to which I have secured by suitable screws 13 or otherwise the foot of a frame 14. The frame 14 supports a track 15, herein represented as a round rod held in a socket 16, the said track serving to guide a take-up or slackthread controller, shown as a carriage 17, having a suitable stud 18, preferably of vitreous material, under or partially about which passes the thread 1 on its way from the reel to the traverse b and the spindle (l or the shell thereon which is to receive the thread, the said shell used in Fig. 1,being supposed to be conical as represented in Fig. 9, the shell in Fig. 1 being partially filledwith thread so that itis not visible. The carriage 17 has a finger 19 which contacts, with the smooth guiding surface 20 of the track frame when the carriage is being moved up and down on the track for distances suitable to control such slack threads as will enable the machine, all other things being equal, to be run properly. The surface 20 near its upper end is, however, curved upwardly, as at 21, so as to let the said finger 19 pass about the portion 22 on the track frame, and following said surface, owing to the pull of the thread upon the stud 18 due to a knot or obstruction in the thread at the swift or reel, cause said finger to pass under the stop trigger 23 shown as a latch pivoted at 24 on apart of the track frame, said fingerin such position and under such circumstances acting to lift. the stop trigger into the dotted line position Fig. 5, and cause the shoulder 25 of the stop trigger to be lifted oif a toe 26 at the upper end of the drop it pivoted at 28 on the track frame thus releasingsaid drop enablingit to falland strike the pin 3 at the end of the leg lever It, thus lifting the inner or rear end thereof and putting it into the path of movement of one of the teeth mof the ratchet or stop wheel m said tooth in the further rotation of the wheel acting on one end of said leg lever to swing the leg to cause the same, or a part carrled by it, to act on the cam surface at the upper side of the lever g and turn it about its fulcrum g thus moving the lifting device f upwardly and causing it, acting against the winding roll 24, to lift it from contact with the rotating drum a, such break of contact immediately stopping the rotation of the spindle d. To enable the winding operation, however, to be stopped in case the thread breaks or becomes too slack, I have connected to the stoptrigger 23 a rod 30 which is extended through suitable guides 31, 32, said rod acting upon v one end of a slack-thread trigger 33 pivoted at 34: on the track frame, the opposite end of said lever being herein shown as entering a slot 35 in the track 15, said slot being convenient as it enables the lever to be so located as not to be strained laterally out of place, and so that it will always be Within the range of movement of the carriage 17. In case the thread breaks it no longer supports the carriage 17, and as a result, it drops and strikes the slack-trigger, turns it from its full into its dotted line position Fig. 5, and through the rod 30 lifts the stop trigger, releasing, as before, the drop lever 27. I prefer in practice to restrain in a measure the upward movement of the carriage 17 under the pull of the thread coming from the swift or reel, so that certainly a safe amount of strain may be put upon the thread, to thus aid in overcoming any adhesion of one layer of thread to another before the carriage will rise far enough to swing aboutthe track as described and lift the slack-trigger to effect the stopping of the winding mechanism, and to efiect this result, I have added a spring 36 which may be of india rubber. It will be understood that the traverse b' guides the thread y and that the said traverse, moved by the crossing grooves rather widely distributed, causes the thread to be laid in long spirals, one layer crossing another diagonally layer after layer. A cross wound mass of thread, such as herein provided for, may readily be delivered from the thread mass of whatever form without rotating the thread mass.

Prior to my invention I am not aware that thread has been wound directly from skeins into a conical mass or upon a conical shell, or, in fact, a shell ofany kind, and while I have shown one form of take-up or slack-thread controller which operates well to accommodate the maximum and minimum slack of the thread when winding the latter from the skeins upon different portions of the conical shell, yet this invention is not limited to the exact form of take-up or slack-thread controller shown, nor to the exact shape shown for the triggers, as it will be obvious to those skilled in the art that other forms of such devices might be employed to effect the same result without departingfrom the spirit and scope of my invention.

Instead of the particular drum herein shown, I may substitute as an equivalent the form of drum shown in my United States Patent No. 499,665, granted June 13, 1893, and so also the spindle and the cone or conical shell upon which the thread is wound may be substantially as in my United States Patent No. 499,667, granted June 13, 1893. I

This invention is not limited to the exact form of carrier shown for the cone, nor to the exact form of traverse mechanism for laying the thread from end to end of the cone in long spirals.

The lever g, the leg, the leg lever, the ratchet wheel, and the drop constitute what may,for brevity be designated as stop-motion devices, but instead of the particular devices shown, I may use any other usual or suitable stop .motion devices intermediate the stoptrigger and the devices for rotattng a shell of Whatever form, said stop motion devices, when acted upon by or through the take-up or slackthread controller stopping the winding of the thread on the drum.
