Application filed March 15, 1912. Serial No. 683,984.

To all whom it may concern Be it known that 1, GRANT Srrr, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Driving Mechanisms for Winding-Machines, of which the following is a specification.

This invention relates to winding machines of the kind in which horizontal thread-guide-carrying rails are reciprocated from levers arranged to oscillate in vertical planes parallel with the vertical planes of the rails from a suitable rotating cam whose axis is horizontal.

In the usual construction of this class of machines, the oscillating motion of the levers soon becomes very irregular, resulting not only in undue wear and tear on the parts but, what is of more importance, irregular conditions in the winding of the packages being produced. This is due principally to the fact that, however well the levers may be fitted at their fulcrum-bearings and regardless of all effort otherwise to prevent lost motion between any of the parts, the point of contact or bearing of each lever with the cam being offset relatively to its fulcrum-bearing a torsion of the lever is produced which results in unequal wear at the fulcrum bearing, on the cam and the cam-engaging portion of the lever, and elsewhere.

My object is to construct the traverserail operating mechanism of a machine of the kind indicated so as not only to eliminate the cause of the torsional displacement of the levers but so as to hold each lever positively against such displacement and otherwise kept true to the kind of movement it is intended to have.

A further object of the invention is to impart greater stability and rigidity to the framework or rigid part of such a mechanism.

In the accompanying drawings, Figure 1 is a side elevation of a part of a winding machine improved according to this invention; Fig. 2 an end elevation thereof; Fig. 3 a plan view, partly in section; and, Figs. 4: and 5 are sectional views on lines 03-40 and y of Fig. 1.

The spools a on which the winding is accomplished are suitablv journaled in the frame I), resting on and being thereby driven from wheels 0 on the shafts ol journaled in said frame, said shafts being suitably driven and one of them driving the gear 6, fixed on a sleeve 7 journaled on a shaft 5/ projecting from the frame 6, through gearing it, all in substantially the well known manner.

iis a cam of usual form, also fixed on said sleeve.

j j are the traverse rails sliding in the usual manner in the frame and each having a vertically slotted extension 70.

At a suitable distance below the cam two forked brackets Z Z project from the frame and on a pin m in each as a fulcrum-bearing is pivotally supported a lever 72.

Each lever has secured therein a stud 0 on which is ournaled a roller 0' received by and playing in the vertical slot of extension 70, the roller being retained on the stud by a cotter pin 0 each lever also carries a bolt 29 secured in place by a nut 39 and on which is ournaled a flanged roller 2) (held in place by a cotter-pin 39) between the flange of which and nut 79 the bracket la (receiving the roller in its horizontal slot 1*) is received rather snugly. The power is transmitted to each bracket is (and hence to rail j) from lever n at 0 the parts 17' and 79 serve to retain the bracket is parallel with the lever, so that the rail j is kept true in its guiding means.

The acting face of the cam is the one appearing in elevation in Fig. 2. Usually the levers are made to engage the cam through the medium of bearing-portions on the levers which project laterally (as seen in Fig. 2, for instance), toward each other, from the levers, and this, under the pressure of the usual spring 8 pulling the draft-bar t which loosely connects the levers toward the frame, produces the undesirable torsion already mentioned. Tn the present instance the bearing portion of the lever consists of a bracket to which is fixed to its narrow face (each lever being flattened in the usual way) on the side thereof adjacent the cam and carrying a roller 0 which bears against the cam. The lever being straight as seen in Fig. 2, this construction brings its bearing-portion into the plane in which the lever moves, so that torsional strain is eliminated.

Sidewise movement of the levers is pre vented by the brackets w, bolted to and projecting from the frame, the same having longitudinal slots 00 in which the levers move, 3 being a roller revoluble in each bracket u and serving as an anti-friction device affording lateral support for the lever against the side of the slot w. Thus, even though the cam should wear a groove in the roller 2) (as in time it does), no side- Wise movement being allowed, the cam runs continuously on the same part of the roller, occasionally rising to the high or unworn part thereof to vary the traverse of the rail at times and thus make the disposition of the windings irregular.

Rigidity and stability are imparted to the shaft 9 and the brackets w, and conse quently the moving parts which they sup- 'port and control are maintained in a constant relation to each other, by the triangular brace 2 which is rigidly secured by screws or otherwise to the extremities of said shaft and brackets.

By my construction lost-motion and undue wear of the moving parts are reduced to substantially such a condition that they are practically inconsiderable, with the very important consequence that the reciprocating motion of the thread-guide-carrying rails has that uniform character which is found indispensable in the regular and accurate placement of the windings.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent is 1. In a mechanism for reciprocating a pair of traverse rails, the combination of the frame, levers fulcrumed in said frame on a horizontal axis, a rotary cam, a shaft projecting from the frame at right angles to the fulcrum axis of said levers and affording a journal for the cam, said levers being held against the cam, a pair of brackets projecting from the frame and confining said levers to planes of movement each at right angles to the fulcrum axis of said levers, a brace tying the free ends of said shaft and brackets rigidly together, and means to rotate the cam, substantially as described.

2. In combination, the frame, a horizontal rail arranged to reciprocate therein longitudinally, a rotary cam journaled in the frame, a lever member operatively connected With the rail and fulcrumed in the frame on a horizontal axis at right angles to the rail, a bracket projecting from the frame and having a slot parallel with the rail and receiving the lever member, rollers arranged at right angles to each other and journaled in said lever member and one being received in and substantially fitting between the sides of the slot and the other bearing against the am, means to urge the lever member toward the cam and means to rotate the cam, substantially as described.

3. In combination, the frame, a horizontal rail arranged to reciprocate therein longitudinally, a rotary cam journaled in the frame, a lever operatively connected with the rail and fulcrmned in the frame on a horizontal axis at right angles to the rail, a bracket projecting from the frame and having a slot parallel with the rail and receiving the lever, a bracket u attached to the lever, rollers journaled in the bracket u at right angles to each other and one being received in and substantially fitting between the sides of said slot and the other bearing against the cam, means to urge the lever toward the cam, and means to rotate the cam, substantially as described.

4. In combination, the frame structure, a horizontal rail member arranged to reciprocate therein, a rotary cam journaled in the frame structure, an upright lever member fulcrumed in the frame structure at one end and movable in a plane parallel with the rail, means to urge the lever member toward the cam, means to rotate the cam, said structure including means to confine the free end of the lever member to said plane, and coupling means between the lever member and rail member confining the rail member to a plane parallel with the plane of movement of the lever member, said means including a vertical slot in one member and a stud on the other member penetrating said slot and a horizontal slot in one member and a stud on the other member penot 'ating the l'iorizontal slot, one slot being arranged above the other, substantially as described.

In testimony whereof I atllix my signature in presence of two witnesses.
