JACK-SPOOLER.

To all whom it may concern:

Be it known that I, THOMAS H. N U'rn, a citizen of the United States, residing at East Providence, in the county of Providence, State of Rhode Island, haveinvented certain new and useful Improvements in J ack-Spoolers, of which the following is specification. 7

My invention relates to j ack-spoolers and consists of improvements in the traversemechanism' therefor. The object of my improvement is to provide a simplified attachment universally. applicable to practically all types of spoolers and adapted to be driven from a going part of the machine to operate the front and the back traverse at different speeds. VMy improved device consists essentially .of a self-contained, coordinated mechanism which can be attached to any type of spooler without alteration or adjustment in the main elements of the machine, and which may be driven therefrom to effect a quick traverse of the front guidebar and a vrelatively slow traverse of the rear bar.

The invention is fully described in the following specification, illustrated by the accompanying' drawings, in which like reference characters designate like parts. In the drawings Figure 1 is an end elevation of a usual type of j ack-spooler illustrating my improved traverse-mechanism applied thereto;

Referring first to Fig.1, B designates th 7 end frame of a conventional form of jackspooler to which my attachment may be applied and it is to be understood that the invention is also adaptable to various other types of machines of this class.

to use in connection with this well-knownmechanism of the jack-spooler as follows: To the side of the frame B, I attach a bracket K into which is screwed a headed stud 70 adapted to serve as a bearing for a rotatable traverse-cam L. The cam Lis of a usual typefo'rmed with a helicalgroove Z on its periphery as shown most clearly in Fig. 8; Secured to ormade integral with the cam L is a gear Z adapted to mesh with a similar gear J fast on'the end of the drumshaft d. Extending upwardly from the bracket K is an arm'k' carrying a stud k on which is pivoted a rockable traverse-arm or lever M. At its lower end the lever M carries a stud m on which isjournaled a L. Theupper arm of-the leverM is formed with a longitudinal slot m through which.

'rolljm engaging the groove Z in the cam erse-bar F. In order to render the traversing-mechanism interchangeably and universally attachable to all types ofspoolers, I provide a novel form of adjustable means for connecting it with the traverse-bar as follows:

A clamp-member N formed with a reotangular slot at is adapted to slip onto the end of the traverse-bar F, and projecting from its side is a horizontal arm or rod n. The clam-p N is secured to the bar F by means of a set-screw a to allow it to be adjusted in position longitudinally thereon and the arm n is adapted to receive the hub 0 of an arm 0 formed with a slot 0. The hub 0 is secured to the arm a of the clamp N by means of set-screws 0 0 which allow for lateral adjustment of the arm 0 to bring it into position adjacent the side of the traverselever M. The lever M is coupled to the arm 0 to impart reciprocating motion to the traverse-bar F through the means of a stud P adjustable in the slot 0. As shown in Fig. 2, the stud P passes through a collar or bushing 20 fitted to the slot m of the lever M and arranged with washers p, p on either side thereof. A thumb-nut p is screwed onto the stud P against a washer p to bind the latter and the washer 10 against the arm 0, while the bushing p is left free to slide in the slot m of the lever M. If preferred, the stud P might be formed with an enlarged head adapted to fit the slot m in the lever M and having its shoulder abutting the side of the arm 0 so thatthe washers could be dispensed with. By adjusting the stud P up or down in the slot 0 the range of action of the lever M may be altered to vary the length of traverse imparted to the bar F by the cam L.

Secured to the side of the frame B are two brackets R and U formed with bearings for a horizontal shaft R, see Fig. 1. Usually the bracket R and shaft R constitute standard elements of the machine as originally designed. Suitable collars r, '2" on the shaft R abut the ends of the bearing on the bracket R to hold the shaft from longitudinal movement, and at its forward end is keyed or otherwise secured a toothed gear V adapted to serve as a ratchet-wheel. Screwed into the lower end of the traverselever M on the opposite side from the rolls m is a stud m which serves as a bearing for a pawl V arranged with its ends adapted to engage the teeth on the ratchet-wheel V. Referring to Fig. 3, the bracket U is formed with a cylindrical pocket at in which is slidably mounted a plug U pressed outwardly by a helical spring M2. The end of the plug U is fiatted off at n and beveled on its opposite side at a to adapt it to engage the teeth on the ratchet-wheel V to act as an escapement or check-pawl for the latter. When the wheel V is turned in the direction indicated by the arroW a Fig. 3, through the action of the pawl V oscillated on the lever M, the check-pawl U will be forced back against the pressure of its spring a from the action of the teeth on the wheel V riding across the bevel a On the other hand, the pressure of the spring a maintains the pointed end of the pawl constantly in engagement with the teeth on the ratchet V to prevent backward rotation of the latter during the rearward movement of the actuating-pawl V.

Secured to the shaft R at the opposite end from the ratchet-wheel V is an eccentric-disk XV which serves as a reciprocatingmeans for the rear traverse-bar G, see Fig. 4:. At the end of the bar G, I attach a clamp-member W similar in form to the front traverse-clamp N and provided with a depending arm w. The clamp-member W is adjusted in position and secured in place on the bar G by means of a set-screw w to adapt the arm w to bear against the periphery of the eccentric W. To maintain the arm to in operative relation to the eccentric V a cord or chain 2 is attached to it at a and leads over a rod 2 or other suitable support on the machine-frame, with a weight Z suspended at its end.

Having now described the construction and arrangement of my improved mechanism in detail, the method of operation of the complete machine will next be explained: It is to be understood that in practically all spoofing-machines of this type the main elements, such as the drivingdrum, the spool-supports and traverse bars, are of substantially the same construction and arrangement as here shown, except that they difi'er slightly in dimensions and detail of coordination. The eccentric-shaft R, as before mentioned, is also usually provided on the machine frame as an element of the back-traverse mechanism. My present improved attachment is applied to use in connection with these standard parts of the machine in such manner as to require a minimum of new elements and practically no alteration or rearrangement of the basic mechanism. The bracket K, the cam-gear LZ which it supports, and the connected traverse-lever M with its pawl V are the principal elements of my new mechanism, and together with the arm 0, bracket U and clamps N and WV constitute practically all the parts necessary to be added to the main machine. These elements are attached in place without the necessity of any machining or fitting except in some instances where holes must be provided for the bracket bolts. In any event, however, my new attachment can be applied to the spooler with very little labor and at very slight expense. After the parts are fixed in position as hereinbefore described the mechanism functions as follows: The yarns :2 lead across the guide-rod H and through the thread-eyes g in the rear traverse-bar G, thence under and around the tension-roller 'I", up under the pressureroller T, whence they are then drawn across the machine to the lease-rod EL, From the rod E they pass through the eyes or slots in the front traverse-bar F and thence lead tothe barrel of the spool S. IVhen the machine is started the driving-drum D rotates the spoolvS through contact with its barrel 5 and. the yarns y are thereby wound onto the barrel while the spool rises with the growth in diameter of the winding. Meanwhile, during the rotation of the spool, the gear J on the drum-shaft (Z drives the gear Z to rotate the cam L, and the latter imparts an oscillating motion to the traverse-lever M as the roll m travels in the groove Z. This rocking movement of the lever M is transmitted through the stud P to reciprocate the front traverse-bar F with a relatively quick movement, and the extent of traverse of the bar may be regulated as required by simply adjusting the stud P up or down in the slot 0. That is to say, the traverse of the bar F is adjusted in accordance with the number of strands or ends being wound onto the barrel 8 so that the yarn will completely fill the spool between its heads.

As the lever M oscillates under the action of the cam L the pawl V at its lower end acts on the ratchet-wheel V to rotate the shaft R. The rotation of the shaft R turns the cam or eccentric IV to cause it to act on the arm w of the clamp WV to reciprocate the rear traverse-bar G with a slow motion. This slow traverse of the bar G acts to shift the yarns 7 back and forth along the tensionrolls T, T, the object being to prevent them from wearing grooves in the surface of the rolls.

v winding.

I am aware that it is not broadly new in the art to apply front and back traverses to a ack-spooler with means for operating them from the main shaft of the machine. The object of my present improvement is to provide a more simple and eflicient attachment for all types of j ack-spoolers arranged to operate the traverse-bars insuch manner that while the rear traverse is relatively slow, the front traverse-bar is given a quick traverse. Through this improvement the yarn is laid on the spool with a cross-wind so that the individual ends build up in selfsustaining masses and therefore the yarn will deliver more freely and evenly in undown over the ends of the mass so that they will deliver with a 'more uniform tension 7 when the spool is unwound.

In other words, the cross-winch It will be seen that my improved device is particularly simple in construction and compact in arrangement while providing the maximum efiiciency for the purpose de-. scribed. The parts are few in number, easily attached tothe'machine, and in addition the brackets and clamps are adjustable to varying conditions so that they render the device universally applicable to practically all types of machines.

Various modifications might be. made in the form and construction of the parts of my improved device without departing from the spirit or scope of the invention; therefore, without limiting myself to the exact embodiment shown and described, what I claim is I '1.
