- tiple winding machines to wind tubes and cones .of lengths greater than heretofore possible. A further object is to improve the winding of multiple tubes and cones of the lengths now wound on such machines and also of tubes and cones of increased length. A still further object of the invention is the provision of means for facilitating the adjustment of the machine for different length tubes or cones. I I

For the attainment of these and such other objects as shall herein appear or be pointed out I have shown an embodiment of my invention in the accompanying drawing, wherein:

Fig. l isa front View of the winding mechanism, showing particularly, the traverse bar and associated parts;

Fig. 2 isa plan view thereof;

Fig. 3 is asection taken on the line 33 of Fig. 2; and

Fig. 4 is a plan view similar to Fig. 2 but showing the winding of a pair of cones, rather than tubes. I

The pair of tubes I and I are placed on the rotating spindle 2 and the'thread or yarn guided to wind properly on the rotating tubes, by a pair of porcelain guides, respectively, 3 and 3' provided at the upper ends of guide fingers 4 and 4' secured to the traverse bar 5 in a manner to be described more fully. The upper ends of the guide fingers, near the porcelain guide, are

provided with projecting tongues 4t whichride on the top edge of a presser or back plate 6, the tongues being bent over they top of the plate, as best seen in Fig. 3, to hold the fingersloosely to the plate.

Back plate B is secured, as by machine screws to a balance lever 1 pivoted to the frame of the machine at 10.; the other endof the lever 1 is balanced by a counterweight 1b. As a result of this construction, the counterweight urges the lever in a counterclockwise direction as viewed in Fig. 3, causing the back plate 6 to press theguide fingers, and the porcelain guides against the tubes, the lever and all the parts turning clockwise as thediameter of the tubes build up. The securement of the plate 6 and lever 1 is made so as to provide a slideway 8 for the traverse bar 5. The right end of the traverse bar is provided with a block!) from which depends a pin 9p receivable in the groove log of drum cam in, for the 5 purpose of rapidly reciprocating the traverse bar. As the traverse bar is reciprocated and the tubes, rotated, the two threads guided by the pair of porcelain guides 3 and 3 of the traverse bar,

are uniformly and simultaneously woundon both 104 tubes 1 and I. In multiple winding machines heretofore made, only tubes of a limited length could bewound in multiple (i. e., in double) tubes of a greater length would have to be wound on single machines, i. e., on machines having a single guide on the traverse bar. If it were attempted to wind longer tubes on a double machine, not only would the tubes beunsatisfactory but there would be caused frequent breakage of the machine, especially, the traverse bar. The back plate casting 6 is machined, 6m, on the side against which the guide fingers reciprocate. As

heretofore made, the guide fingers .4 and 4 were made of steel sufficiently thin so as to be capable -of adjustment relatively to the machine surface 6m of the back or presser plate 6 and the two tubes 4 and 4'. In spite of the accurate machining of the back plate and the adjustabilityof the guide fingers, it has not been practical to wind two tubes (or two cones) beyond a limited'length.

The traverse bar of this invention'is made in two separable parts, a rear portion I5 at the rear end of which is secured the pin block 9 and at the front of which is secured the guide finger 4', and a front portion l5, at the front end of which is sec'uredthe other guide finger 4. The two portions are joined by a long screw connection, as by forming a long screw thread l5ton the rear portion l5 and a long tapped hole. or socket I5s on the front portion i5,,into which the 40 threaded portion is screwed. The threaded screw and the tapped socket are cut so that the two fit easily. By this provision of a screw or threaded joint between the two guide fingers, an

angular adjustability is: provided to enable any of thetwo, guides is not subject toany possible inaccuracy of the plate, either of the part of the plate associated with that one of the'guides or the part of the plate associated with the other de I Y The screw thread serves not only to permit of this angular adjustability or compensation, but also is made sufiiciently long, i. e., with sufficient thread engaging surfaces, to serve'to fasten the two portions of the traverse bar together in a manner that will withstand the very considerable acceleration and deceleration forces caused by the rapid reciprocation of the traverse bar.

A further advantage of making the traverse bar in two parts is the facility airorded of adjusting the machine for difi'erent lengths of tubes. In multiple or double winding machines as heretofore made an entire new traverse bar is required for each length of tube to be wound. In a machine incorporating this invention, all that would be required in adjusting the machine for tubes of desired length would be to attach a front portion 15 of the prescribed length, it being underi stood that a set of such portions will be on hand each for a different tube length.

Both objects'angular adjustability and adjustment for length-are attained in machines for winding cones, as well as tubes (as illustrated in Figs. 1 and 2). The invention is applied in the same manner to cone winding, Fig. 4, in which cones 2| and 2| are being wound, the parts of the machine bearing the same reference characters as in Figs. 1 to 3, except that the back plate 6 is now provided with two machined surfaces 16m and Him inclined in a line parallel to that of the taper of the cones.

By reason of the. screw or threaded joint l5s--l5t, Fig. 4, between the front portion i5 of the traverse bar and the rear portion l5 thereof, the guide finger 4 may move along the machined guide surface [6m at an angle to the straight line in which the traverse bar itself reciprocates. Also, by reason of this joint and because the rear portion l5 of the traverse bar'may turn to a suflicient extent in its guideway 8, the guide finger 4' may move along the machined guide surface [6121' at an angle to the straight line in which the traverse bar-itself reciprocates. The angle made by machined surface Him/is substantially equal to that made by l6m, with the line of traverse bar travel. Moreover, because of the said joint, any difference in these angles will be compensated for.

While the drawing shows the application of the invention to two tubes (Figs. 1 and 2) and two cones (Fig. 4) it is evident that the invention may be applied to a machine in which three or more cones or tubes are simultaneously wound.

- In the case of three tubes (or cones) there would be two screw joints, one between each adjacent pair of tubes; in the case of four tubes, thre joints would be required, etc.
