J., assignor to Sipp- Eastwood. Corporation, Paterson, N. 1., a'cor- 'jporation of New'Jersey AppHcation January 3'1, 1934, Serial No. 709,121 Q 2 claims; F 01. 74-54 (usually the lever) is equipped with a stud adjustable toward and from the levers fulcrum and engaging in a slot in the other of such parts, the stud being adjustable so that, without changing the throw of the lever, the throw of the rail and hence the extent of the traverse may most pronounced at each change from one to the other reciprocating direction, and this results in a motion of the rail which is lacking in smoothness, or jerky, and which therefore produces faulty winding, besides involving wear and tear on certain parts of the mechanism. Espe cially is this true where, as is commonly the case,

the rail is mounted toslide in guides which, as usual, are upwardly open, and it is of course accentuated when the stud is below the rail so that the effect is so to tilt the latter that its free end would rise.

According to this invention the rail, at the end portion thereof which is connected with the lever, is confined against shifting in the up and down direction; in the example this is accomplished by providing the supporting structure with a fixed guide extending parallel with the normal path of reciprocation of the rail and the rail with a head or extension having a cylindrical bore receiving and snugly fitting the shaft.

In the accompanying drawings a winding machine of the common duplex class constructed in accordance with this invention is shown,

Fig. 1 being a side elevation of the end portion of the machine;

ings 5 and having their spindle whirls 6 resting on the wheels; the thread-guiding or'traverse rails 7 extending and arranged to slide horizontally in open bearings 7a (and see also patent to Root No. 1,849,693); the levers'8 for reciprocating said rails and having their fulcra at 9 and oscillating in vertical planes toward and from said end frame; the slotted guides 10 projecting from said end frame and receiving in their slots the rollers 11 on the levers; and the means to oscillate said levers reversely to each other comprising a cam 12 against which a roller 13 on each lever bears and revolving around the fixed shaft 14 projecting from said end frame and having a gear 15 which is intergeared by the gearing 16 with one of the shafts 3, and also comprising the yoke 17 engaged with the levers and between them connected by a spring 18 with the frame and thus acting to hold the levers against the cam. There may also be, according to a'well known construction, a cam-gear 19 journaled on the shaft 14 (the projecting sleeve 19a of this gear affording a bearing for cam 12 and its gear) and by the gearing 16 driven at a different speed from that of gear 15, the same by its cam-hump 192) being adapted at intervals to engage a hump 15a on the gear 15 and shift the latter and hence said cam, the levers and rails to change the traversing position of the rail for a purpose well known in the art.

The connection between each traverse rail and rail rectilineally and horizontally as hereinbemeans of bolts 22 said end of the rail is clamped,

the sleeve being parallel with the rail. Aflixed by screws 200 to the fiat inner face of the projection is the arm 23a of a vertically elongated member 23 having a vertical slot 232) and a bottom This member is beside the horizontal slot 230. lever and, the latter being confined by the means 10-11 to an upright plane, the head formed by said sleeve and said member clamped thereto is confined to an upright plane and the rail thus kept from rocking transversely by a stud 24 on the lever penetrating slot 230 and being equipped with means 25, as a washer, lapping member 23 substantially as in my said patent. Also, as in my said patent, a stud 26 adjustable in a longitudinal slot 8a in the lever engages in the slot 231) of member 23 so that when the lever is oscillating traverse motion, of more or less extent according to the adjustment of said stud, Will be imparted to said member and hence to the rail. The sleeve and member 23 as indicated form in effect a two-part head or extension on the rail end by which the rail is connected to the lever and by which such head, and consequently the rail end, is confined to horizontal rectilineal movement by the sleeve having its bore fitting and being slidable on a horizontal guide which is here a stube-shaft 27 projecting from the end frame.

The two stub-shafts 2'7 and the shaft 14 are held in rigid relation to each-other by a triangular brace 28 having sockets fitted over these shafts and secured thereto by screws 29.

Since the guide formed by each sleeve 20 and forming part of the mentioned head or extension is confined against tilting by the guide formed by the corresponding horizontal rigid shaft 27 any tendency ofv the lever, acting through the device 23, to tilt the traverse rail is opposed by the latter guide regardless of the point at which stud 26 may impart the rail-reciprocating impulses, so that the rail having no other movement than its truly it and the rail are confined against tilting.

2. A winding machine including supporting structure having upwardly open bearing means, a rail slidable in the bearing means, a guide below 'oneend of the rail having means by which said rail is clamped thereto, means, engageable with the guide vertically out of alinement with the rail, to reciprocate the latter, and a fixed guide projecting from said structure parallel with the rail and along which the first guide is slidable and by which it and the rail are confined against tilting.
